An Unusual Allergic Reaction to Polyglactin 910 Suture Material Following Muco-gingival Surgery

The use of sutures is common following oral surgical procedures. The risk of developing an allergic reaction to a suture material is possible. This study presents a case of a 29-year-old male who suffered from Oral Contact Allergy (OCA) from a polyglactin910 suture material. The patient presented with gingival recession of the maxillary right canine, bicuspids and first molar requiring muco-gingival surgery to cover denuded root surfaces. After harvesting the sub-epithelial connective tissue graft from the palate, which was sutured using polyglactin910, the patient developed a significant allergic reaction to the suture material presenting as large palatal swelling and itching. The donor site - Hard palate – completely healed in few weeks’ time after suture removal.
