ited in terms of availability of materials and may result. in donor site morbidity [1]. Using allografts may be. more desirable in some cases, but the possible immune. reaction and infection transmission limit their applica-. To overcome these limitations, various synthetic. bone substitutes made of me tal, ceramics, polymers,.

and various composite structures have been introduced. to accelerate and improve the process of bone regen-. eration; though their safety, effectiveness and efficacy.

remain uncertain [2]. Recently, by increasing the rate of. invasive surgical procedures especially in the fields of. orthopedics and dentistry, the bone repair techniques.

using new materials are getting more popular. The new. materials which are used should help us reduce the op-. eration time, scar size, post-operation pain, and also. improve patient recovery [3,4].

One of the best materi-. als which fulfill these requirements is chitosan []. Recently a special attention has been made toward. using the materials which are derived from nature. Such materials would have some advantages over syn-.

thetic ones. Most notably, they have been shown to. Ezoddini-Ardakan et al. yield faster healing with less incompatibility in human. Chitosan is a chitin derived polymer which is pro-. duced by deacetylation of chitin. Chitin is mainly found.

in exoskeleton of crustaceans and also in some fungi. These shells which were simply regarded as g arbage in. the past times are now seen as a valuable source of chi-. tin [9]. Many biomedical applications have been identi-. fied for chitosan including wound healing, bandage,.

skin grafting, homeostasis, hemodialysis, drug delivery,. preventing d ental p laqu e, h yperten sion contro l, calciu m. absorption, bilirubin absorption, and cholesterol control. Several desirable properties have been described for. chitosan including high osteoinductivity, osteointegra-.

tability, easy application and gradual biodegradability. that makes it a good candidate for bone regeneration. Some researchers have studied the effects of chitosan. compounds on animal bone repair [].

the characteristics of chitosan as a biomaterial for bone. repair, in this study, investigation was made to see the. effects of chitosan on dental socket repair after tooth. In this study, we recruited 12 female orthodontic pa-. tients with the age of 16 to 24 years old.

They were un-. dergoing extraction of first premolar teeth as part of. their orthodontic treatment and were qualified as ASA. class I category. After extraction of the teeth, dental. socket on the right jaw was filled with chitosan powder. and duly sutured. The cavities on the opposite side got. sutured without filling by any excessive material.

san powder was procured from capsules made by Spring. Leaf Co. Each capsule contains mg of chitosan powder. The contents of 20 capsules were. removed to special plastic bags and sterilized by gamma.

After anesthetizing the patient by injecting 1½ car-. rou Pakhsh Pharma. Tehran, Iran , an intra-. sulcular incision was made to raise a distal papilla and. marginal gingival.

This exposed the marginal bone to. allow visualization of the alveolar bon level. of all the first premolars was done at one setting for each. patient using a straight elevator and forceps. After ex-.

traction of all the premolar teeth, 2cc of fresh blood was. collected from the extracted tooth socket and mixed with. the chitosan powder for producing a thick pasty material. with which each socket on the right side was filled, and.

the socket on the left side was left unfilled to be used as. None of the sockets were covered with a barrier. membrane or mucoperiosteal flap. The distobuccal, me-. siobuccal and palatal papilla with attached gingival at.

the extraction sites were stabilized with two interrupted. suture to reduce the opening of the socket and also the. amount of exposed material. All the patients were pre-.

scribed a course of prophylactic antibiotic therapy and. pain medication with post operative instructions for 7. days, at which point the suture was removed. The dress-.

ing of all wounds was performed by the same nurse. The patients were recalled 10 weeks after surgery for. periapical dental radiography. Periapical radiographs of.

the extraction sites were obtained using Planmeca. Proline X-ray unit Planmeca Co. to 10 KVP, 8 mA and 0. The radiographs were. taken by the same technician under the same conditions. The films were processed by Velopex dental x-ray film. processors Medivance Inst ruments Ltd. at 27 ˚ C for 4 minutes Figure 1.

The radiographs were digitized by a scanner with DPI resolution and the densitometry was done using. Adobe Photoshop software Adobe Systems Incorpo-. rated, San Jose, CA on a personal co mputer.

Each socket. was vertically divided into 3 equal zones: coronal, mid-. dle, and apical. Regenerated bone density was assessed. Figure 1. Periapical radiography of mandibular first premo-. lar in case a and control b ; and maxillary first premolar in. case c and control d. in each zone, in both intervention and control cavities.

The density of normal adjacent bone to each cavity was. also assessed to be compared with rege nerated bone. Data were analyzed by SPSS ver. cago, USA using Paired t-test and Wilcoxon signed rank. P-values less than 0. After explaining the research protocol, an informed. consent was obtained from each subject.

The proposal of. this study got approved by the Ethics Co mmittee of Sha-. A total o f 2 4 dental so ckets in 12 ortho dontics p atien ts. were studied. The sockets were either in upper or lower. After ten weeks of tooth extraction, the density of re-.

The mean density of regenerated bone in each. zone of repaired tooth socket for the case and control. groups is presented in Table 1. The mean density of regenerated bone was signifi-. cantly higher in middle and apical zones of case group. compared to control group, whereas this difference was.

not considerable between the coronal zones of the two. As the normal bone density differs from one person to. another, the density of regenerated bone in each patient. is compared with the maximum bone density of the same. The mean bone density of the mandibles of the.

participants was For each person, the ratio of regenerated bone density to. the maximum mandibular bone density in both groups of. sockets was calculated. These figures and their statistical. analysis results and the differences between the two.

groups are summarized in Table 2. In this study, an investigated was made on the bone. healing effects of chitosan on 12 patients who referred. for premolar teeth extracti on for orthodontic purposes.

sand drawbacks []. Moreover, this method is asso-. nological reactions [9,10]. Chitosan has been reported as. a biodegradable and biocompatible substance [20], and.

according to numerous studies it is effective in restoring. bone defects []. Chitosan can be used as a bio-. compatible coating for orthop edic and craniofacial im-.

plants [14]. Minimal inflammatory reactions have been. observed in tissues which have been in contact with the. chitosan co ated pins; while the healing sequence of bone.

remains typical. So, chitosan coatings have shown to be. able to develop suitable osseointegration of dental and. orthopedic implants [27]. Chitosan microparticles can. also improve drug delivery to localized areas which. leads to increased and accel erated bone growth [28]. Several studies have investigated various effects of.

chitosan on bone healing and raised some hypotheses on. its mechanisms []. For instance, according to a. study by Chevrier and co-workers, chitosan increases the.

vascularization of blood vessels and stimulates budding. tissue tissue comprising of budding capillaries and fi-. Park and co-workers [33] reported that spongy chito-. san activates osteoblasts and could increase osteogenesis. Klokkevold [34] also reported that chitosan increases the.

activity of osteoblasts and helps bone formation. Lee and. co-workers [35] reported that spongy chitosan supports. the proliferatio n of osteoblasti c cells. Considerin g the rate.

of bone formation and the speed of bone regeneration in. the dental cavities see Tables 1 and 2 , results of this. study are in agreement of the above mentioned studies. Kim and co-workers [36] studied chitosan and its de-. rivatives and their applicati ons in tissue engineering,.

such as the formation of skin, bone, cartilage, liver,. nerves, and blood vessels. In the present study, chitosan. powder is u sed to see its effect on bone r egener ation. was interestingly found that after a period of 10 weeks,. the bone density in the apical zone of the sockets treated.

surgeries and implants. This new formulation can be. used in improving the macroporosity of apatitie frame-. works, in order to help reduce the stress shielding in an.

implant-bone complex, also implant longetivity. In our. study, higher speed of bone formation in the apical and. middle zones of the dental sockets filled with chitosan. can be justified by an increase in scaffold and position-. ing of the bone forming cells in this framework.

Xu and. co-workers [38] used CPC for repair of teeth and cra-. niofacial tissue. In their study, CPC was used for repair. of periodontal bony tissue and loose teeth following. They used tetra-calcium phosphate and chito-.

san in order to make non-rigid and strong calcium phos-. phate cement, which they believe is more useful in repair. of periodontal tissue and bone surrounding an implant. Chitosan has been used also for producing fast-setting.

CPC and makes it resistant to washout [38]. can solve the problem of handling the particulate form of. calcium hydroxyapatite as it can stabilize the p articles in.

It also helps bone formation and. makes orthopedic procedures and craniofacial implants. In the present study, the chitosan powder was.

mixed with blood of each person and filled in the dental. socket, and it was found that bone tissue regeneration. will be faster in chitosan-filled socket than untreated. Ma and co-workers [40] studied the heat sensitive ef-. fects of chitosan hydrogel on periodontal bone healing.

Pabale, Supreet. Shirolkar, Subir. Sarkar, Somen. Roychowdhury In the quest for discovering ideal dental materials, biomaterials or those derived from biological sources play a special role because of their varied usages and inherent biocompatibility.

Introduction After cellulose, chitin is the most abundant biopolymer found in the natural world. Source Citation. Gale Document Number: GALE A Related Subjects Metronidazole EDTA Biological products. The possibilities of application of chitosan are so huge and fascinating as well as not quite discovered.

Proprieties of chitosan like biocompatibility, anti inflammatory and others could give promising results in periodontal care or wound healing after teeth extractions. The aim of this work is to review possible applications of chitosan in dentistry area. Keywords: chitosan, biomedical, bioengineering materials, biodegrability, selective permeability, polyelectrolyte action, natural polysaccharide.

Biomaterials are those non-living materials used in the medical, biomedical and other fields, aiming to interact with the biological system. One of the most important fields of applications of natural compounds it is medicine. Such materials would have some advantages over synthetic ones.

Materials derived from the nature, have been shown to yield faster healing with less incompatibility in human beings. The new materials which are used should help to reduce the operation time and improve patient recovery.

The development of reconstructive surgery, cardiac surgery, transplantation and dentistry would not have been possible without progress in the field of material science, chemistry and technology polymers for biomedical and bioengineering materials. One of the new and promising biomaterials being used in dentistry is chitosan.

Chitosan and its derivatives have excellent biocompatibility, non-toxicity to human beings, biodegrability, reactivity of the deacetylated amino groups, selective permeability, polyelectrolyte action, antimicrobial activity, ability to form gel, film and sponge, absorptive capacity, anti-inflammatory and wound healing.

The use of biopolymers in the treatment of diseased tissues was started in the area of dentistry. The scientific and technological advances in the area of biomaterials and medical devices have allowed a considerable evolution in this area, in particular, focusing on new biomacromolecules and biocompatible materials for clinical use.

Chitin Figure 1 is a natural polysaccharide from crustacean shells, insect cuticles, and on fungal cell walls is the second most abundant polymerized carbon found in nature. This copolymer obtained is biodegradable, consisting of D-glucosamine units containing a free amino group.

Chitosan can be used in a large number of industrial applications, among which the following stand out: biocompatibility, biodegradability, antibactericidal, emulsifying and chelating properties.

Figure 1 Schematic representation of the primary structures of a chitin and b chitosan. The purpose of this study is to investigate the potential of Chitosan, based on promising properties and reliable biological functionalities emphasizing the dental area.

Look for new methods and applications due to their excellent biocompatibility. The discovery of chitosan was in by Rouget when the chitin was subjected to a treatment with hot potassium hydroxide solution.

In the period of , Gilson confirmed the presence of glucosamine in chitin and in the same period was named chitosan by Hopper-Seyler. Chitosan is a straight chain, cationic polysaccharide that occurs naturally or can be obtained by deacetylation of chitin.

The average degree of acetylation of chitosan is a measure of the average number of 2-acetamidedexosi-D-glucopyranose and 2-aminodeoxy-D-glucopyranose units. The relative percentage of these units has a direct influence on the solubility of chitosan and is an important parameter to determine the average degree of acetylation or indirectly the average degree of deacetylation, which in this way represents the concentration of amino groups, besides exerting a great influence on the physical properties, chemical and biological.

The amino groups of chitosan are more reactive with respect to the acetamido groups of chitin. The free electron pair of nitrogen in the amino groups is responsible for the adsorption of metallic cations. The average degree of deacetylation determines the fraction of amino groups that are available for interaction with metals.

The protonation of amino groups in acid solutions is responsible for the electrostatic attraction of anions. Unlike chitin, chitosan is soluble in dilute acid medium forming a cationic polymer that confers special properties differentiated with respect to the vegetal fibers.

However, the solubility is dependent on several parameters, such as the degree of deacetylation, molar mass, concentration of acid and biopolymer and ionic strength. Chitosan, for the most part, consists of 2-aminodeoxy-D-glucose units linked by β- linkage.

In addition to the flexible structure of the polymer chain, chitosan has potentially reactive functional groups: amino -NH2 groups, several primary and secondary hydroxyl groups at the C-2, C-3 and C-6 positions, respectively, which have strong affinity with water.

Due to its characteristics of biodegradability, biocompatibility, hydrophilicity, antibacterial properties, bioactivity and to be processed in different forms solutions, blends, sponges, membranes, gels, pastes, tablets, microspheres and micro granules, among others chitosan is widely used.

Also because it comes from natural and renewable resources. Properties of chitosan that are perhaps the most important to dentistry are bioactivity, anti-inflammatory, wound healing, hemostasy and bone repair. To use of chitosan appears to be very promising recent introduction in the design of new materials.

Associations between chitosan and calcium-phosphate mineral maintain a high degree of bioactivity, which appears to be favored by the functional and structural versatility of chitosan.

For example, in the field of ceramic materials, which are widely used in dentistry, a common characteristic of bioactive glass-ionomer cements is that of determining the formation of a biologically active layer of carbonate-hydroxyapatite that bonds to the collagen fibers of the tissue with which it interfaces.

In dental material can be many challenges of antibacterial agents. Concentration of the agent must be sufficiently adequate to inhibit or reduce the formation of bio-film but does not exceed the level of cytotoxicity.

Effect should not be limited in time and mechanical, chemical and aesthetic properties of material may not deteriorate. Chitosan as a natural carbohydrated biopolymer with a unique structure and properties, may fulfill the criteria described above. Chitin and chitosan have been investigated as antimicrobial agents against a broad range of target microorganisms such as algae, bacteria, yeasts and fungi in vivo and in vitro experiments involving chitosan in various forms solutions, films and composites.

gingivali s. This can lead to changes in permeability and barrier properties causing leakage of cell contents. Such antibacterial action has demonstrated by chitosan against oral bacteria. There are many tests for use chitosan as antimicrobial agent in composites, dental materials and oral hygiene products.

According to Kong et al. The antimicrobial activity of chitosan for gram-negative and gram-positive bacteria, ranges from up to , mg and up to 1,mg , respectively. To date there is enough evidence to support that chitosan molecular mass can influence the solubility and its antibacterial activity.

During invasive dental treatments can occur bleeding disorders and dentists must be ready for it. To get the most effective way to control bleeding and wound healing, the best and popular solution is to use hemostatic agent.

They have been carried out the study, which aimed to evaluate the effectiveness of chitosan on wound healing and hemostasis after teeth extraction. For this purpose was used Hemcon Dental Dressing HDD. In US, military is manufactured Hem Con Bandage HB forms of freeze dried chitosan.

HDD is oral hemostatic wound dressing delivered from HB. Dressing reduces pain and recovery time by creating a physical barrier to protect the wound surface.

The results proved that HDD without the need of additional hemostatic measures was effective to stop bleeding after dental extraction. This can explain that specific cells, which are involved in the process of wound healing are affected by chitosan.

Before and after surgery it is important to the efficient operation of the immune system. Immunomodulators act as regulators of the body resistance to various kinds of infections. Chitosan has immunomodulators property and stimulate macrophages to release IL-1 which in turn stimulates fibroblast proliferation and collagen influence the structure.

Chitosan in general release - acetylglucosaminidase N like a product of hidrolitic and enzymatic degradation, increase biosintesis of hyaluronic acid and extra cellular components related with scarring formation. After applying chitosan wounds were characterized by an increased number of collagen and osteopontin and a heavy infiltration of polymorphonuclear leucocytes PMN.

The cicatrizing capacity depends upon degree of deacetylation DD of chitin and chitosan. Chitosan has higher DD than chitin which results in the appearance of a more active fibroblasts and greater resistance to bursting wounds. The natural defense answer of our body caused by damaging factors of chemical, physical or biological is inflammation.

In dentistry we are often faced with certain periodontal diseases that cause this condition. Studies have shown that chitosan and its derivatives are able to influence this process in many different ways. It is associated with the presence of N-acetyl-D-glucosamine, which stimulates inflammatory cells such as macrophages, fibroblasts and PMN neutrophils.

However there is a question mark, whether equally good results will be achieved in tests in vivo. Therefore, further studies are required in this direction.

There are many serious diseases that cause damage to the bone and which constitute a great challenge. These include for example, tumor resection and osteolysis due to dental and bone lesions or periodentium tissue disorders.

By increasing the number of invasive surgical treatments, in fields such as dentistry and orthopedics, it is extremely important improvement and the search for new materials for bone repair techniques.

These materials should help in the shortened time treatments, reducing the size of scars and pain after surgery, as well as a faster recovery of the patient. Features such as chitosan biodegrability and biocompatibility enable application of this biomaterial for hard tissue repair process.

It works on the principle of temporary scaffolding in a bone substitute, pending resorption of the implant and replacement by natural bone. Many researches have been made, confirming that properties of chitosan has incredible impact on bone regeneration and healing. Some studies have shown that chitosan in the form of sponge activates osteoblasts and could increase osteogenesis.

Regarding the properties of chitosan as a biomaterial for bone repair, research was carried out to see the effects of chitosan on dental socket repair after tooth extraction.

After 10 weeks, found very interesting results. The bone density in middle and apical section of the sockets treated was significantly more. In each patient, the bone density in epical and middle sections was increase The results confirm that in chitosan-filled socket bone tissue regeneration will be faster than untreated dental socket.

Rapid development of civilization and technology involve a number of advantages and also many consequences. More often we are turn to the nature in search for materials and solutions that will be friendly to us and our environment.

Chitin and chitosan are one of those products. Properties of chitosan such as biocompatibility, biodegrability, non-toxicity, antibacterial opens many possibilities of application. The main of them are: water and waste treatment, agriculture, food and beverages, paper industry, cosmetics and toiletries, biopharmaceutical and the major one is biomedical area.

Table 1 Chitosan application in dentistry area Application of chitosan in dentistry is the subject of research for decades. Thanks to its characteristics and possibility to create a complex for what may be in various forms.

Chitosan in the form of gel and hydrogels applies to the treatment of chronic periodontitis and canker sores. Toothpastes, mouthwashes and chewing gums based on chitosan and herbs fullness functions antimicrobial effect on oral bio film and reduction of the number of S. mutans in the oral cavity.

Endodontic cements based on chitosan reduces inflammation and support bone regeneration. Chitosan has been studied due to the superior properties of this biopolymer and along of the years comes incentivating new researches at the tissue engineering area.

Chitosan offers great opportunities for a bright future, we are focused to bring new possibilities to the chitosan-based products. It is proved that this biopolymer has enough capability to be used as substitute skin, blood anticoagulation, antimicrobial, anti-inflammatory, bone healing and regeneration as such an infinity of others fantastic applications.

The potential of Chitosan shown in this article focused manly in dentistry area. This is an open access article distributed under the terms of the, which permits unrestricted use, distribution, and build upon your work non-commercially.

Share this:	This material is also biocompatible and biodegradable. It is positively charged and combines with the bacterial cell wall and membrane with bacteriostatic and bactericidal results [15,16]. Muzzarelli, et al. This is especially important since S. mutans is known to be the principal etiological factor of dental caries [18]. The aim of the investigation is to further develop and evaluate a versatile designed chitosan based bio-active materials for the prevention of demineralization around the orthodontic brackets, chitosan mouth gels as alternative materials and compare the performance of the Clinpro and Tooth Mousse as commercially available protective agents via the Adhesive Remnant Index ARI and failure site assessment was completed immediately after each shear bond strength de-bonding under x 20 magnification. Preparation of bracket cements modified with chitosan hydro gels: general protocol. The bio-active containing gel was prepared by dispersion of 0. Extracted non-carious, intact, human premolars stored in water containing a few crystals of thymolat 4°C were used within two months. Samples were checked before use for any damage caused by their removal. The teeth were fixed in self-curing acrylic resin placed in flexible molds with the roots embedded in the acrylic and the crown exposed and oriented perpendicularly to the bottom of the mold. Premolar stainless steel brackets Equilibrium 2 Roth prescription, 0. slot size, Dentaurum Orthodontics, Ispringen, Germany were used. The buccal surface of each tooth was cleaned with non-fluoride oil-free pumice paste using a nylon brush attached to a slow-speed hand piece for 5 s, and then the tooth was rinsed with water for 10 s and dried with an oil-free air spray. Brackets were bonded to the teeth according to the manufacturer 'sin-structions for the adhesive system and stored in distilled water at 37°C until testing. Bracket debonding was performed 72 h after bonding in a material testing unit Instron with an occluso-gingival load applied to the bracket base. The shearing rod was adjusted each time so the shearing blade is parallel to the base of the bracket contacting it in a reproducible way each test. The crosshead speed was 2. The Adhesive Remnant Index ARI and failure site assessment was completed immediately after each shear bond strength de-bonding under x 20 magnification [26]. Descriptive statistics, including mean, standard deviation, and minimum and maximum values of the shear bond strength, were calculated for each of the adhesive systems tested. A Kruskal-Wallis test was used in conjunction with a Bonferonni test to compare the differences in the ARI scores between the groups. Statistics were carried out using Prism 6 Statistical Package. Two types of commercially available enamel protective agents were used in the current study: Tooth mousse GC Corp. All materials were used according to the manufacturers' instructions. Each group was divided into two subgroups; in the first one, orthodontic brackets were bonded with self-etching adhesive system and in the second one, a conventional adhesive system was used. The SEM images were obtained to characterize the microstructure of the freeze-dried propolis containing bioactive chitosan gels and are presented in Figure 1. It could be seen that the gels displayed a homogeneously pore structure. It was thought that the micro-porous structure of the gels could lead to high internal surface areas with low diffusional resistance in the gels. The surfaces of the gels were also presented Figure 1. Figure 2 gives the shear bond strength values MPa after 72 hours of storage of samples in artificial saliva using conventional. In general there was an increase in bond strength of the enamel treated with the chitosan containing hydrogels containing bio-actives compared to the bond strength of the conventionally bonded teeth. An increase in the shear bond strength was also previously reported [19] for chitosan containing hydrogels [20]. The additional advantage of the system may suggest that, chitosan: bioactive interaction with crystalline hydroxyapatite structure of the enamel layer increases the enamel bond strength observed especially in the case of the direct bonding between the hydrogel and the enamel surface interface. The increase of the bond strength is also attributed to the unique capacity of chitosan as well as biological properties of bio-actives such as propolis, copaibaoil and oblepicha oil to influence bioadhesion of the hydrogels and promote the formation of the reparative hydroxyapatite interface and therefore starting all important hydroxyapatite regeneration process making these type of designer bioactive hydrogels as important prototypes in development of bioactive restorative materials. The results of the Kruskal-Wallis test showed that the ARI scores, Figure 3, were significantly different between the groups. Results of one-way ANOVA showed also that the type of preventive agent used on the enamel significantly influenced the ARI scores distribution; there was a significant difference depending on whether it was chitosan: bioactive hydrogels containing propolis, copaiba oil or oblepicha oil or Clinpro that was used before bonding with self etching primer or with phosphoric acid etching. The lowest shear bond strength was recorded with the samples treated with Clinpro or Tooth Mouse before bonding. Figure 2: Shear bond strength of hydrogels after 72 hours of bonding to orthodontic brackets to enamel. Figure 3: Frequencies of the ARI scores for the groups of interest. the orthodontic brackets especially using self etching adhesive system; the shear bond strength in this group was significantly lower than the shear bond strength in the other groups. In case of Clipro as a protective agent, the loss in shear bond strength could be attributed to the resistance effect that the outer enamel layer acquires from the fluoride content of the Clinpro which may be of significant effect especially when using self-etching primers in bonding due to their more superficial etching effect compared with the etching of the conventionally used phosphoric acid. Previous studies [] with Scanning Electron Microscope SEM indicated that although self-etch priming agents have the potential to etch the enamel surface, the etching pattern is less deep compared to the etching pattern of phosphoric acid. A chemical bonding capacity through the interaction between some functional monomers and the calcium of residual hydroxyapatite may contribute favorably to the bonding effectiveness [ 29] but, fluoride affects the enamel surface rendering it more resistant to demineralization. Fluoride in low concentrations favors the formation of fluoro-hydroxyapatite, which is less susceptible to acidic solubility than hydroxyapatite [34,35]. Therefore, it is recommended to use these preventive agents after bonding the brackets when self-etch adhesive systems are used. The shear bond strengths recorded in this study were sufficient for clinical use in all the groups presenting different combinations of adhesive systems and enamel protective agents as well as control groups. The average range of bond strength was suggested by Reynolds [35] to be 5. In-vitro and in-vivo studies of SBS are both needed; in-vitro measurements of shear bond strength provide useful information about the bonding efficiency of different types of materials, but the actual performance of these materials can only be evaluated in the environment where they were intended to function [39]. In the case of lower shear bond strength, upon pretreatment of the enamel surface with the Tooth Mousse especially upon using self etching adhesive system, the results are in line with previously reported study that calcium phosphate in the form of CPP-ACP added to a Tooth Mousse can enhance the level of re-mineralization of enamel subsurface lesions when the product is used in situ [40]. The distribution of the ARI scores was assessed in this study under x 20 magnifications [36]. Although, different quantitative and qualitative methods have been used to assess the ARI scores after orthodontic bracket debonding and quantitative methods were found preferable. If accurate evaluation of the adhesive remnant is required [37]. ARI score evaluation system has proved to be of value in the studies of orthodontic adhesive systems. ARI score system is a quick and simple method that needs no special equipment. Although SEM evaluation might be more accurate than evaluation under x 10 or x 20 magnifications, it is harder to be reflected in clinical applications [38]. The distribution of the ARI scores was found different between the major groups under investigation such as Clinpro, Tooth Mousse and Bioactive hydrogels containing chitosan derivatives. In the Clinpro and control groups, both self-etching and conventional etching subgroups, less adhesive remnant tended to be seen left on the enamel surface after debonding. This could be attributed to the chemical bond between the resin infiltration and the adhesive resin. Based on the above findings, we conclude the following: Significantly lower shear bond strength was recorded when Clinpro was used before bonding using the selfetching adhesive system. The adhesive remnant was not different between the self-etching and the conventional etching subgroups. References Top. Gorton J, Featherstone JDB.
