Impact of ICON on the Adhesive Microleakage Underneath Orthodontic Bracket A. Soares e Lucas Abstract- Objectives: The aims was to assess the changes in tooth orthodontic bracket interface micro-leakage after applying a caries resin penetrated to the sound enamel tooth surface. Materials and Methods: Sixty human maxillary first premolars were collected, randomly separation of the teeth into two groups. The experimental one (treated with ICON) was categorized in to three subgroups (n= 10 each) (ICON in distal water, ICON in cow milk, ICON in Coca cola) while control group was classified three subgroups (n=10) (control in distal water, control in cow milk, control in Coca Cola) incubation time persisted three weeks in total. Results: A one-way analysis of variance (ANOVA) produced a significant difference between all experimental groups (ICON in distal water, ICON in milk, ICON in Coca Cola drink) and control subgroups (control in distal water, control in Cow milk, Control in Coca Cola). According to the results of the Mann- Whitney U test, ICON pretreatment tooth samples had significantly lower mean values of microleakage than non- ICON tooth samples. The control group in the energy drink subgroup had the highest mean microleakage value when compared to the other subgroups, whereas the resin infiltrated group in distal water had the lowest mean value. Conclusions: Orthodontic adhesive (control group) revealed that a resin penetrate on a sound enamel surface prior to orthodontic bracket bonding reduced bracket tooth interface microleakage in all examined groups. The ICON-infiltrated surface was discovered to provide a secondary preventive strategy against white spot lesion development and reducing micro-leakage under orthodontic brackets .

It is a loss of marginal integrity that permits white lesions to grow around and under the bracket, potentially resulting in reduction the bracket bonding strengths. (1) White spot lesions are clinical and cosmetic issues characterized by enamel demineralization, tooth discoloration, corrosion, and bond strength deterioration. (2) Since orthodontic braces, bands, ligatures, and other orthodontic accessories are difficult to clean and increase bacterial biofilm accumulation on tooth surfaces, white spots develop around them.(3, 4) White spot lesions have become more predominant with fixed Author: e-mail: alucastunes@gmail.com orthodontic appliances.(5, 6) Oral hygiene, sex, orthodontic treatment time, wheat consumption, and diet all have an influence on the appearance of white spots lesions.(7,8) To avoid additional demineralization and cavitation, these lesions should be recognized early.(9) restorations, crowns, and veneers, which necessitate enamel reduction beyond the demineralized area, possibly even to the dentin (10), are among the options for treating white spot lesions. To remineralize these lesions on the surface, casein phosphopeptide amorphous calcium phosphate (CPP-ACP) products as MI Paste and MI Paste plus, as well as fluoride dentifrice, mouthwash, gels, varnish, and gels, can be utilized. A resin infiltration material (ICON), have recently been encouraged. (11,12) which is a substance with a low viscosity (13). The primary knowledge of resin infiltration is to use capillary forces to enter and encloses the porosity volume of underlying imperfections, replenishing missing minerals, enclosing hydroxyapatite crystals, and micromechanically linking the residual enamel prisms. (14,15) The current research was deliberate in order to evaluate the variations in tooth orthodontic bracket interface microleakage after smearing a caries resin penetrated to the sound enamel tooth surface. II. M aterials and M ethods Ethical approval The ethical approval was attained by the REC of the University of XXX. a) Study sample design Sixty human maxillary first premolars extracted for orthodontic purposes were used in the study. In order to avoid microbial growth, teeth were maintained at room temperature in a glass container in a solution of normal saline (Panther, USA) containing 0.1 percent thymol (Sigma, USA) that was altered daily. (16,17) The study excluded teeth having caries, enamel abnormalities, abrasions, attrition, fractures, or any other developmental problems. (18) Buccal surfaces were scrubbed and polished for 15 seconds with a slow speed handpiece and non-fluoridated pumice and a rubber polishing cup, then rinsed and dried with oil-free air steam for another 15 sec.
