Oral Contact Allergy to Suture Material Resulting in Connective Tissue Graft Failure: A Case Report

Abstract

Introduction: Sutures are used on a daily basis for many dental surgical procedures. However, the risk of oral allergic reaction triggered by suture material cannot be excluded. This case describes possible oral allergic reaction to suture material following periodontal surgery. Case Presentation: The patient presented with gingival recession of the mandibular anterior sextant requiring root coverage procedure. The patient had a significant allergy history to multiple medications and materials. After harvesting the graft, tissue was sutured using poliglecaprone 25 sutures. The patient developed an allergic reaction to the suture material presenting as severe intraoral swelling and itching. The graft was devitalized and eventually failed. Conclusions: To the best of the author's knowledge, this is the first case of possible allergic reaction to suture material in dental surgery reported in the literature. It is important to evaluate patients for any allergy history, in addition to medical and medication history, before any dental surgery. Patients with a significant allergy history, as in this case, are at higher risk of developing allergic reaction to any of the dental materials used in periodontal surgical procedures. Awareness of allergic reactions and the necessary management and intervention are critical for patient safety.
