過去8年間における顎骨内囊胞の臨床統計的観察

Abstract

Clinico-statistical observation was made in patients with jaw cysts referred to the Department of Oral and Maxillofacial Surgery in the last 8 years. Jaw cysts were classified into odontogenic cysts (475 cases, 81.5%) and non-odontogenic cysts (108 cases, 18.5%). Of odontogenic cysts, radicular cysts were seen in 318 (54.5%), residual cysts in 31 (5.3%), follicular cysts in 90 (15.4%), odontogenic keratocysts in 30 (5.1%), non-keratinized primordial cysts in 5 (0.9%) and calcifying odontogenic cysts in 1 (0.2%), respectively. Of non-odontogenic cysts, incisive canal cysts were seen in 5 (0.9%), globulomaxillary cysts in 4 (0.7%), median palatine cysts in 1 (0.2%), postoperative maxillary cysts in 88 (15.1%), traumatic bone cysts in 7 (1.2%) and static bone cavity in 3 (0.5%), respectively. In follicular cysts, the effect of root canal treatment of deciduous teeth on these cysts was made. Root canal treatment of deciduous teeth was involved in 22 cases (71%) out of 31 cases of follicular cysts. In 30 odontogenic keratocysts, dentigerous type was seen in 13 (43%) and primordial type in 17 (57%).
