Conventional caries removal method using burs may result in excessive loss of sound tooth structure and often induces pain and discomfort to the child. In the era of minimally invasive dentistry, conventional cavity preparation methods are outdated. Several alternative methods are available nowadays. Among the most commonly accepted method is chemo mechanical caries removal. Chemo-mechanical caries removal has so far been a promising method in pediatric dentistry, especially for anxious or medically compromised patients, it helps to reduce the patient’s stress and allows the more selective removal of carious tooth structure. But these alternative methods shouldn’t compromise the quality of restoration. AIM: To find out the Effect of different caries removal techniques on the Shear bond strength of composite resin to dentin. Materials and Methods: 20 deciduous teeth divided into 2 groups. Group A: conventional group, caries removal done using tungsten carbide bur, Group B: Chemo mechanical group caries removal is done using Brix 3000 and restored with composite. Thermocycling was done and shear bond strength was evaluated. Result: No significant difference in shear bond strength of composite restoration following tungsten carbide and Brix 3000. Conclusion: Caries excavation with a CMCR agent does not negatively affect bonding performance to residual affected dentin.
