The Effect Force Orientations on Dental Enamel Attrition
Objectives: We ought to analyze the enamel’s attritional behavior under forces applied in different directions
Methods: Thirty-two teeth were set in a custom-made dental attritional device and subjected to force applied in four different directions, and two magnitudes (high/low). force was monitored continuously using a pressure transducer.
Enamel tissue loss was measured using a high-resolution confocal disc scanning measuring system through surface profiles analysis.
Results: Calculation of enamel surface loss material revealed that, in both the low and high force groups, the highest wear was produced by the occlusal-cervical direction (817.8 μm and 10051 μm) and the lowest in the cervical-occlusal direction (177.1 μm and 821.7 μm), while in other horizontal directions (right/left) the attrition values were in between; 383.3 & 308.9 μm for the low force group, and 2721 &1161 μm for the high force group. Statistical significance was found between the occlusal-cervical direction and the other three in both force groups (p=0.003).
Conclusions: The findings of the study emphasize the anisotropic quality of dental enamel.
Since the tooth hard tissue is unrenewable and irreversibly lost, the findings of the study are utterly important in that they shed light on an undervalued factor of dental attrition. While the force directions in mouth aren’t controlled naturally, in many situations, clinicians are well aware of the abrasional procedure fashion they perform, hence, it is advisable to consider the study findings.
