Summary
This systematic review found no strong evidence for occlusion-based treatments for tooth attrition. Further research is needed to establish effective protocols for managing tooth wear and related occlusal factors.
Area of Science:
- Dental Science
- Biomaterials Science
- Clinical Dentistry
Background:
- Tooth attrition, a form of dental wear, is often associated with occlusal factors and masticatory function.
- Understanding the relationship between occlusion and attrition is crucial for developing effective treatment strategies.
Purpose of the Study:
- To systematically review existing literature on the relationship between tooth attrition, occlusal factors, and masticatory function.
- To identify evidence supporting occlusion-based treatment protocols for managing tooth attrition.
Main Methods:
- A comprehensive literature search was conducted in PubMed and the Cochrane Library (1980-2006) using keywords 'tooth' and 'wear'.
- Studies were systematically screened and selected based on predefined inclusion and exclusion criteria, focusing on in vivo studies related to occlusal factors, function/dysfunction, and attrition.
- Data extraction and correlation analysis were performed on 33 included studies, with inter-observer agreement assessed using Cohen's kappa.
Main Results:
- The systematic search yielded 1289 references, with 33 studies ultimately included after rigorous screening.
- Analysis of the included studies revealed a lack of robust evidence to support any specific occlusion-based treatment protocol for managing tooth attrition.
- Some correlations were noted between attrition and anterior spatial relationships, bruxism, and tooth loss, but evidence regarding temporomandibular disorders (TMD) and attrition was limited.
Conclusions:
- Current evidence does not support specific occlusion-based treatment protocols for tooth attrition.
- While attrition may coexist with bruxism and be influenced by tooth loss, its relationship with TMD signs and symptoms remains poorly understood.
- Further research is required to elucidate the complex interplay between occlusal factors, masticatory function, and tooth attrition to guide clinical management.
