“…Oral ulceration with bone sequestration (OUBS) designates a site‐specific oral ulcer that covers exposed, non‐vital bone in patients lacking any etiological factor known to induce osteonecrosis (Gadiwalla & Patel, ; Khan, Morrison, Ruggiero, et al, ; Palla, Burian, Klecker, Fliefel, & Otto, ). It has been reported in the literature under various descriptive names (Otto et al, ; Palla et al, ), including lingual mucosal ulceration with mandibular sequestration (Dhanrajani, ; Jackson & Malden, ), lingual mucosal ulceration with bone necrosis (Alkabouli, Kokovic, & Emad, ), lingual mandibular bone sequestration (Gündüz, Özden, Kurt, Bulut, & Günhan, ), lingual mandibular sequestration and ulceration (Peters, Lovas, & Wysocki, ), lingual mandibular sequestration with ulceration (Kessler, ), lingual mandibular osteonecrosis (Cerruto, Ugolini, & Cozzani, ), oral ulceration with mandibular necrosis (Villa & Gohel, ), oral ulceration with bone sequestration (Carrard, Sieck, Chaves, Filho, & Rados, ; Farah & Savage, ; Palla et al, ), mandibular bone exposure and osteonecrosis (Kharazmi et al, ), bone sequestration (Friel & Macintyre, ), bony necrosis and sequestration in the mandible (Fisher, ), spontaneous alveolar bone sequestration (Danesh‐Meyer, ), idiopathic exposure and sequestration of alveolar bone (Sonnier & Horning, ), oral ulceration (Scully, ), or osteonecrosis (Almazrooa, Chen, Nascimben, Woo, & Treister, ; Gabric, Seiwerth, Baraba, Vucicevic & Boras, 2017; Kharazmi, Nilsson, & Hallberg, ).…”
