Introduction: Recently, the use of long-term systemic medications, including biologicals, to manage various chronic systemic diseases has increased. The association between these medications and the pathogenesis or healing of endodontic diseases remains poorly understood. This systematic review aimed to evaluate the relationship between the long-term use of systemic medications and the incidence, prevalence, and/or healing of endodontic diseases and conditions.
Methods: A comprehensive literature review was conducted using the electronic MEDLINE Ovid, Scopus, Embase, Cochrane, and PubMed databases followed by manual searching and citation mining for all articles eligible per the inclusion criteria.
Results: A total of 2470 citations were screened, and 12 articles met the inclusion criteria and were included in this review. The selected studies included 9 cohort or cross-sectional studies and 3 case-control studies with a low to moderate overall risk of bias mostly. Some medications were associated with either an increased or decreased prevalence of apical periodontitis, whereas other medications were associated with an incidence of pulp calcification or cervical root resorption.
Conclusions: Systemic medications may be associated with the incidence, prevalence, or healing of endodontic diseases and conditions, but the level of evidence is low. This warrants more well-designed longitudinal clinical studies on the role of chronic systemic medications as well as controlling for medications when the systemic diseases are studied.
