Background: Successful adhesion in restorative dentistry depends greatly on effective enamel surface conditioning. Conventional phosphoric acid etching has long been considered the gold standard for creating micro-retentive enamel surfaces. However, simplified adhesive approaches such as self-adhesive systems have been developed to reduce clinical steps and technique sensitivity. Despite their convenience, concerns remain regarding their ability to produce adequate enamel surface alterations for optimal bonding. Mechanical pretreatment methods, such as rotary brush conditioning, may enhance enamel surface roughness and improve the interaction between enamel and adhesive systems.
Aim: To assess enamel surface morphological alterations after rotary brush conditioning when used in conjunction with self-adhesive systems.
Materials and Methods: This in vitro experimental study included 100 extracted human premolars with intact enamel surfaces. The samples were randomly divided into four groups (n=25 each): Group I – control (no treatment), Group II – rotary brush conditioning, Group III – self-adhesive system, and Group IV – rotary brush conditioning followed by self-adhesive system application. Standardized enamel areas were prepared on the buccal surfaces of the teeth. Rotary brush conditioning was performed using a low-speed handpiece with pumice slurry. Enamel surface morphology was evaluated using scanning electron microscopy (SEM). The degree of surface roughness, microporosity formation, and etching patterns were assessed. Statistical analysis was performed using STATA software, and intergroup comparisons were conducted using one-way ANOVA.
Results: The combination of rotary brush conditioning and self-adhesive systems produced the highest degree of enamel surface alterations, including increased surface roughness and greater microporosity formation. Significant differences were observed among the groups (p < 0.001).
Conclusion: Rotary brush conditioning enhances enamel surface modification and may improve the effectiveness of self-adhesive systems by promoting favorable morphological changes in the enamel surface.
