Abstract:

Objective: To assess the curative effect of preserving normal pulp vitality of the non-focused teeth after the treatment of jaw cysts by fenestration manipulation. Methods: A total of 16 patients with large jaw cysts in our department from 2017 to 2018 were selected. We assessed the pulp vitality of the non-focused teeth within the cysts before operation, and then performed fenestration for the treatment. Patients were followed up within 2 weeks to 12 months to assess the pulp vitality of the non-focused teeth in the cyst. As soon as the cyst cavity became decreased, the curettage of cyst cavity was performed. Pulp vitality was tested again after curettage operation. Results: Sixteen patients with large jaw cysts included 68 non-focused teeth. 60 teeth remained the pulp vitality after the operation. Eight necrotic pulp teeth were restored and protected with porcelain crowns after thorough root canal treatment. Conclusion: Fenestration is used to treat large jaw cysts, which not only brings less damage, but also less risk of causing jaw fractures. Moreover, it has obvious curative effect on the protection of pulp vitality of the non-focused teeth within the cyst.

Key words: cyst of jaw, fenestration, pulp vitality

摘要：

目的：评价用开窗术治疗颌骨囊肿时保留非病灶牙正常牙髓活力的疗效分析。方法：选取2017—2018年于我科就诊的大型颌骨囊肿16例。术前评估囊肿内非病灶牙的牙髓活力，予以开窗引流术治疗，开窗术后2周~12个月对患者进行随访，评估囊肿内非病灶牙的牙髓活力；待囊肿变小后行刮治术，术后再次评估非病灶牙的牙髓活力。结果：16例颌骨大型囊肿涉及非病灶牙68颗，术后牙髓活力保留的牙为60颗，对8例牙髓坏死的牙进行完善根管治疗后行烤瓷冠修复。结论：开窗引流术治疗大型颌骨囊肿，损伤小，发生颌骨骨折的可能性低，而且对囊肿涉及非病灶牙的牙髓保护有明显疗效。
