Long-term follow-up evaluations of pulpectomy in primary teeth have revealed retention of ZOE filling particles in the periapical area even after root resorption.
This paper reports a case of a child submitted to pulpectomy with ZOE paste in primary teeth. After 28 months, the filling particles remained, having migrated to the alveolar bone from the gingival vestibular mucosa during permanent dentition eruption. Aesthetics required periodontal surgical removal of the paste particles. Primary teeth submitted to pulpectomy should be evaluated carefully both clinically and radiographically to verify radicular and ZOE filling paste resorption. The consequences of retained particles during permanent dentition eruption are unknown.
对乳牙牙髓切除术的长期随访评估显示,即使在牙根吸收后,根尖区域仍有 ZOE 填充颗粒留存。
本文报告了一例儿童接受乳牙牙髓切除术并用 ZOE 糊剂填充的病例。28 个月后,填充物颗粒仍然存在,在恒牙萌出期间从龈侧前庭黏膜迁移到牙槽骨。为了美观,需要进行牙周手术切除糊剂颗粒。接受牙髓切除术的乳牙应在临床和放射学上进行仔细评估,以验证根尖和 ZOE 填充糊剂的吸收情况。在恒牙萌出期间,残留颗粒的后果尚不清楚。
