Gingival necrosis due to the ill-fitting denture.

We present a case of an 80-year-old male who was referred to the Department of Oral Medicine, School of Dental Medicine University of Zagreb, Croatia due to gingival ulcer which was present for eight days. Clinical examination has revealed exposed bone on the toothless alveolar ridge in the lower molar region on the right side of 0.8 cm in diameter. Otherwise, the patient was taking doxazosin due to urinary problems and ipatropium bromide due to respiratory problems. The patient wore a 6-year-old partial lower denture. He was initially treated with periodontal bandage (Resopack, HagenWerken, Germany) for the first three days and was instructed not to wear the denture; however, no benefit could be seen. Therefore, we added a local corticosteroid (betamethasone) and am oral antiseptic (chlorhexidine digluconate) applied three times a day. After 3 weeks the lesion healed. A list of possible causative factors regarding gingival ulcers is included.
