Abstract
OBJECTIVE: Dental anatomy has been extensively described in numerous textbooks. Nevertheless, there are very few details about the value of the cusp radius of posterior teeth. This in vitro study used a laser profilometer to scan the occlusal surfaces of 21 molar teeth. MATERIALS AND METHODS: The images were analysed with µScan software and the approximate radius of curvature was measured. RESULTS: The values varied between 0.6-2.5 mm. The radius average value was 1.25 mm bucco-lingually and 1.61 mm mesio-distally. CONCLUSIONS: These findings might serve as a guide for different dental biomechanics studies and the conception, design and manufacturing of dental prosthetics.
