To present a case of cervical root resorption affecting all teeth and resulting in multiple tooth loss.
A healthy 33-year-old Chinese male, with no contributory medical or family/social history, presented with generalized cervical root resorption. Lesions varied in severity amongst teeth and even involved an impacted third molar. All cervical root surfaces were affected and lesions often extended coronally, undermining enamel. CBCT demonstrated that the lesions were more extensive and more widely distributed than was seen using conventional radiography. Bone extended into many resorptive defects but without clinical evidence of ankylosis. Periodontal probing, pulp testing, percussion sound and mobility were within normal limits. Key learning points • Aetiology of the generalized idiopathic cervical root resorption is uncertain. • Management is complex, and options have included surgical exposure and restoration of affected sites, extraction and submergence of affected roots. • A staged approach involving early intervention with restoration of resorptive defects, followed by progressive extraction and replacement with implant-supported prostheses is recommended.
报告一例累及所有牙齿的颈椎根吸收病例,导致多颗牙齿缺失。
一名 33 岁的健康中国男性,无任何相关的医学、家族/社会病史,表现为广泛的颈椎根吸收。病变在牙齿之间的严重程度各不相同,甚至累及埋伏的第三磨牙。所有颈椎根面均受累,病变常向冠方延伸,破坏牙釉质。CBCT 显示病变比常规放射学检查更广泛、更广泛地分布。骨延伸到许多吸收缺陷中,但没有临床证据表明有粘连。牙周探诊、牙髓测试、叩诊音和活动性均在正常范围内。
广泛特发性颈椎根吸收的病因尚不确定。
治疗方法复杂,包括手术暴露和受累部位修复、受累根的拔除和埋藏。
建议采用分阶段方法,早期进行吸收缺陷的修复,然后逐步拔除并植入种植体支持的修复体。
