Interaction of Erosion and Attrition on Enamel Wear in vitro

Objectives: The aim of the study was to measure the interaction between attrition and erosion of bovine enamel using several different solutions.

Methods: Thirty six bovine mandibular incisors were mounted in self-curing resin and the facial enamel surfaces were wet ground with #1200 silicon carbide paper. Solutions of acidic beverages (Coca-Cola pH2.5, Sunkist Orange pH2.7, White wine pH3.2) and a mouthwash (ConCol F pH5.6) were used as three-body wear test. Opposing stainless steel antagonist and enamel specimens were worn in impacting-sliding wear machines under a load of 0.228MPa. Different wear behavior of enamel was determined by 3D-laser scanning microscopy, knop hardness measurement and scanning electron microscopy. One-way ANOVAs followed by Tukey HSD test at a level of 0.05 were done.

Results: The mean ± SD were:

Conclusions: Enamel wear tendencies in acidic conditions were significantly when compared to those of neutral conditions (p<0.05), apparently due to an adhesion delamination on wear mechanism.
