Abstract

Background: Conventional cavity preparation and caries removal methods use mechanical means mostly burs, these are often associated with pain and fear, especially among children. Moreover, these techniques present the risk of easily removing healthy dental tissues or damaging the pulp through temperature rise, this may be the origin of discomfort. Minimally invasive technology can be an improvement while addressing these tribulations, confines the use of dental drill, thus improving patient acceptance for treatment. The aim of the study is comparative evaluation of pain perception and behavior during carious dentin excavation using Smart burs and conventional carbide bur. Materials and Methods: Randomized controlled clinical study was performed on 30 children-aged 6–10 years, who presented with bilateral occlusal carious lesions on primary molars. Sixty primary molars were randomly divided into two groups (30 – Smart bur group/30 – carbide bur group) and caries excavation followed by glass-ionomer cement restoration was performed. Wong Baker Facial Pain Rating Scale was used to evaluate pain experience by the patients and Venham’s Behavior Rating Scale was used to evaluate the patient Behavior for both groups. Statistical analysis was done using Wilcoxon Signed-Rank Test. P < 0.05 was considered as significant. Results: The results revealed statistically significant differences between the Smart burs (Polymer burs) and conventional carbides burs with respect to patient behavior (P < 0.005) and the pain perception for caries removal (P < 0.005). Among both groups, smart bur proved more effective compared to conventional carbide bur. Conclusion: Smart bur is more efficacious in terms of improved patient behavior and reducing pain score compared to the carbide bur. Patient acceptance, comfort level, and Behavior was found to be improved with smart bur compared to conventional carbide bur. Combined use of chemomechanical method with conventional carbide bur method demonstrated higher rating of behavior and pain score compared to Smart bur.
