Effect of stress on acid dissolution of enamel

摘要

Objectives: This study was designed to measure the dissolution of buccal enamel of extracted teeth exposed to acid with or without simultaneous cyclic occlusal loading. Methods: Twenty mandibular premolars were mounted in pairs in a servohyaulic testing machineand immersed in 1/100 lactic acid (pH 4.5) or water. One tooth of each pair was subjected to cyclic loading (100 N at 2 Hz for 200,000 cycles), with the load applied at 45 deg. To the tooth axis on the buccal incline of the buccal cusp.
