ABSTRACT

Objective: The objective of this study was comparative evaluation of the cutting efficiency and longevity of differently manufactured dental diamond points with repeated cutting cycles. Methods: Two differently manufactured dental diamond points were scrutinized using a high-speed air-turbine hand piece. Group A were manufactured by proprietary brazing system (PBS) and group B by electroplating method. Variations in the cutting efficiency and longevity of dental diamond points on ceramic blocks were evaluated after repeated cutting cycles. Statistical analysis was done using dependent and independent t-test. Results: The mean total cutting efficiency after 10 cutting cycles in the 2 groups were in the following order: Group A ? Group B. The decrease in the cutting efficiency was found to be greatest after the end of first cutting cycle. Conclusion: Cutting efficiency of dental diamond point manufactured by PBS method was higher and also longevity was greater than dental diamond point manufactured by electroplating method.
