Abstract
ABSTRACT Introduction: Conservative caries removal is the corner stone of minimally invasive dentistry. Ceramic bur is a self-limiting technique for caries removal in pediatric dentistry. Objectives: The aim of the study is to evaluate microleakage of adhesive restorations (in vitro) using Ceramic bur to remove caries versus conventional drilling method. Materials and methods: forty exfoliated carious primary teeth were allocated at random into two groups according to method of caries removal. Group I (n=20) caries removal by Ceramic bur, Group II (n=20) caries removal by conventional tungsten carbide bur, followed by composite restorations of all prepared cavities. Teeth were thermo-cycled for 500 cycles between 5 Ć and 55 Ć, dwell time 10 seconds for 500 cycles and immersed into one percent methylene blue dye for 24h. Teeth were sectioned in a bucco-lingual direction longitudinally and then studied using stereomicroscope at x20 magnification for dye penetration assessment. Data were collected and subjected to Mann Whitney U test. Results: No significant difference was noted in median microleakage scores and distance of stain penetration in millimeters between the two groups (Ceramic bur) and (conventional tungsten carbide bur) at a p value (0.097) and (0.289) respectively. Conclusion: Microleakage of composite restoration is not adversely affected by caries removal using Ceramic bur.
