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

Area of Science:

• Dental science
• Periodontology
• Oral health research

Background:

• Animal models suggest occlusal forces and trauma co-destruct with periodontitis.
• Understanding the human association between occlusal trauma and periodontitis is crucial.

Purpose of the Study:

• To investigate the association between occlusal trauma and periodontitis in a human cohort.
• To identify risk factors contributing to periodontitis.

Main Methods:

• Case-control study with 167 cases and 205 controls.
• Occlusal trauma and other clinical variables were assessed.
• Logistic regression analysis adjusted for confounders was employed.

Main Results:

• Occlusal trauma, pathogenic occlusion, and amalgam restorations were more prevalent in periodontitis cases.
• Cigarette smoking, systemic conditions, amalgam restorations, pathogenic occlusion, and occlusal trauma showed significant associations with periodontitis.
• Amalgam restorations and occlusal trauma remained strongly associated with periodontitis after adjustment for confounders.

Conclusions:

• Occlusal trauma is a significant factor associated with periodontitis.
• Further prospective studies are needed to elucidate the long-term impact of occlusal conditions on periodontitis.
