OCT aspects of dental hard tissues changes induced by excessive occlusal forces

摘要

The purpose of the study was to highlight changes in the hard tissues of a tooth with dental wear as a consequence of excessive occlusal forces using OCT. Methods: a central incisor extracted for periodontal reason was cleaned and it was embedded in a black acrylic resin block. The block was sectioned along the longitudinal axis of the tooth and prepared for OCT analysis. Results: The OCT signal showed differences between the labial and palatal dental hard tissue structures, even in areas without excessive occlusal solicitations. Conclusion: The OCT signal highlights changes of dental hard tissues structures due to excessive occlusal solicitations areas.
