Long-term occlusal tooth wear at the onset of permanent dentition.

ABSTRACT:

Objectives

This study quantified the long-term occlusal wear in the natural posterior teeth and the associations per tooth type within the dentition.

Methods

The sample included 70 orthodontically treated subjects (52 females and 18 males; median age, 14.3 years), followed for a 12.7-year period. They were consecutively selected with no tooth wear-related criteria. Post-treatment (T1) and follow-up dental casts (T2) were scanned and superimposed through three-dimensional methods. Occlusal wear volume of posterior teeth and tooth wear patterns were investigated through non-parametric statistics and analysis of covariance.

Results

There were no significant differences between contralateral teeth. The average occlusal wear per posterior tooth was 2.3 mm³, with
