Evidence of an effect of statins on lesions originating from dental infection. A retrospective clinical investigation

Abstract

Background

Apical periodontitis (AP) is an inflammatory dental disease caused by bacterial infections of the endodontic system. The correlation between AP and cardiovascular diseases. (CVD) has been consistently investigated. Statins are a class of drugs that are used to treat hypercholesterolemia and prevent atherosclerotic vascular diseases. They have other beneficial pleiotropic effects such as anti-inflammatory, antithrombotic, and antioxidant activities. The aim of this study was to evaluate the oral health status and prevalence of AP in patients treated with statins (Group S) in comparison with untreated patients (Group C) to understand whether the anti-inflammatory action of these drugs can influence the prevalence of AP.

Methods

The records of seventy-nine patients (43 men and 36 women, mean age 68 ± 11 years, 1716 teeth) treated with statins and referred to the University clinic for dental evaluation were reviewed. Seventy patients free from systemic diseases and without therapy (39 men and 31 women, mean age 62 ± 9 years, 1720 teeth) constituted the control group. All subjects underwent complete oral, dental, and radiographic examinations to determine the presence and severity of AP. Periapical index (PAI) and decayed, missed, and filled teeth (DMFT) scores were obtained.

Results

AP was significantly less common in Group S (22,8%) than in Group C (50%) (P < 0.05). Furthermore, the mean value of the qualitative rank of the severity of AP (PAI score) was higher in Group C than in Group S (P ≤ 0.05).

Conclusions

Our results suggest that statins can attenuate the prevalence of AP, which is associated to CVD.
