“…Predisposing factors acting simultaneously can lead to severe tooth structure loss, requiring close monitoring and counselling, or complex management strategies [ 5 , 22 , 23 ]. This underscores the importance of diagnosing excessive tooth wear progression at an early stage to take preventive measures before more invasive interventions, such as crowns or extensive bite elevation with composite restorations, are required [ 15 , 24 , 25 ]. Preventive measures could include diet modification; removable splints, especially during sleep; cessation of harmful habits; or covering of tooth surfaces with composite resin to prevent further wear.…”

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 65.2% of teeth showing values greater than 1 mm3. Males, mandibular teeth, and first molars exhibited slightly greater wear levels than females (median, 2.57 and 2.21 mm3, respectively; p = 0.005), maxillary teeth, and first or second premolars, respectively. In all first premolars and in the mandibular second premolars, the buccal cusps were primarily affected with no other distinct patterns. There were weak to moderate correlations between tooth types, apart from certain strong correlations detected in males. Conclusions Posterior tooth wear was highly prevalent after a 13-year period starting at the onset of permanent dentition. The detected patterns are in accordance with the concept of canine guidance occlusion that is transforming into group synergy through function. Clinical relevance The widespread tooth wear occurrence and the high intra- and inter-individual variability underline the need for individual patient monitoring to identify high-risk patients at early stages.
