"Removal of dental calculus deposits is one of the basic parts of professional dental cleaning. Despite the popularity of power-driven scalers, several risks are associated with their use, mechanical damage of the enamel surface being one of the most important. The present study evaluated enamel damage caused by a sonic scaler in different work patterns to quantify the damage and allow a clear comparison. Seventy-five canine teeth were carefully extracted from twenty-three dogs. The scaler was used on a clean surface with several combinations of time (five to twenty seconds) and parts of the scaler (point vs. side of the tip). Subsequently, damaged surface topography was mapped using three-dimensional optical microscopy. The results revealed a high variance in defect depth which was influenced by both factors. Statistical assessment confirmed highly significant (P < 0.001) or at least significant (P < 0.05) differences in data acquired for each group. As expected, the shallowest defects were produced b"@en . "2"^^ . . "50485" . . "RIV/00216305:26210/14:PU112161!RIV15-MSM-26210___" . . "[19249848D6FA]" . .
