Management of Displaced Teeth Due to Unusual Dentigerous Cyst: A Case Report

因不尋常齒源性囊腫而移位之牙齒的處置:病例報告

摘要


The dentigerous cyst arises from the dental follicle of an unerupted tooth. It is the second most common odontogenic cyst after the radicular cyst. A dentigerous cyst often involved mandibular third molars, maxillary canines, maxillary third molars and mandibular second premolars. They are most frequently in patients between 10 and 30 years old. It may cause tooth impaction or migration. This report presented a case of seven-year-old boy who had a swelling of maxillary right primary molar area combined with apical abscess. The radiograph showed migration of the developing premolars. The primary molars were extracted and marsupialization was performed which resulted in a complete resolution of clinical symptoms, spontaneous eruption of premolars and no sign of recurrence. This case demonstrated that marsupialization therapy can be used in preserving a cyst-associated tooth and promoting spontaneous eruption of the involved tooth. It can be considered as a treatment option in similar cases.

含齒囊腫源自於未萌發牙齒的齒囊,是僅次於根尖囊腫最常見的齒源性囊腫,最好發的區域包含上顎及下顎第三大臼齒、上顎犬齒及下顎小臼齒區域,好發年齡為十歲至三十歲,若發生於混合齒列的孩子可能造成牙齒阻生或移位。本案例為一位七歲男童,右上乳臼齒區域齒槽骨膨大合併有根尖膿腫等症狀,X光片顯示小臼齒移位,拔除乳臼齒後以造袋術進行治療,除臨床症狀消除之外,小臼齒順利萌發且沒有囊腫復發之跡象,此案例顯示造袋術可使用於牙齒仍有自動萌發潛力的患者並達到良好成效,可作為類似案例之治療選擇。
