Management of dental care of patients on immunosuppressive drugs for chronic immune-related inflammatory diseases: a survey of French dentists' practices.

Objectives: The aim of the study was to provide an overview of the practices of French general dentists (GDs) and specialists (SDs) concerning the management of patients with inflammatory bowel diseases (IBDs), rheumatic inflammatory diseases (IRDs), and vasculitis on biologic disease-modifying antirheumatic drugs (bDMARDs), conventional DMARDs, or immunosuppressants (ISs).

Materials And Methods: An online national cross-sectional survey with 53 questions was developed by a multidisciplinary team including rheumatologists, gastroenterologists and dentists based on their clinical experience. It was refined following a test with nine dentists in private practice and in hospital before being disseminated to the members of French scientific societies and colleges of dentistry teachers over 3 months. Responses of general dentists versus specialists were compared with respect to their experience in managing patients with IRDs or IBDs, knowledge/training, type of invasive procedure performed, management of medical treatment, perioperative oral-care protocols, and frequency of postoperative complications after invasive dental care procedures.

Result: In total, 105 practitioners fully completed the survey (participation rate 11.1%). SDs more frequently performed invasive surgical procedures and were more aware of the recommendations of learned societies than GDs. They encountered more post-operative complications for patients on bDMARDs. For both SDs and GDs, most patients were managed without stopping treatment and pre- and postoperative antibiotics were prescribed to more than 75% of patients. When medical treatment was stopped, the decision was made by the prescribing physician.

Conclusion: Complications were reported more frequently by SDs when highly invasive procedures were performed on patients under active drug therapy. Certain common procedures, such as scaling and root planing, appear to be safe, regardless of treatment management. However, adapted guidelines for the practice of dentistry are needed to standardize the management of patients on bDMARDS, conventional DMARDs, or ISs.

Clinical Relevance: French dentists perform a wide range of oral procedures on patients on bDMARDS, conventional DMARDs, or ISs under antibiotic coverage and antiseptic mouthwashes. SDs reported more postoperative complications after extensive invasive procedures for patients under active drug therapy, despite their greater knowledge of recommendations on how to manage such patients.
