Occlusal trauma is associated with periodontitis: A retrospective case-control study.

Background: Excessive occlusal forces and occlusal trauma have been implicated as co-destructive factors for periodontitis in animal models. The objective of this study was to assess the association between occlusal trauma and periodontitis.

Methods: A total of 167 cases and 205 controls were included for analysis.

Association between traumatic occlusal forces and periodontitis: A systematic review.

Objective: Occlusal adjustment is commonly recommended for patients with periodontitis and traumatic occlusion. The objective of this systematic review was to analyze available evidence for the association between traumatic occlusal forces and periodontitis.

Methods: Two focused questions were proposed: What is the effect of traumatic occlusal forces on periodontal parameters in patients with and without periodontitis? And what is the effect of occlusal interventions on periodontal parameters in patients with periodontitis? A systematic review of clinical and observational studies was performed and presented in narrative form.
