摘要/Abstract

摘要： 目的观察对唇颊面深龋采用化学-机械法去龋时选择不同去龋止点的效果,为深龋治疗方法和适应证的选择提供参考。方法选择诊断为深龋且接受选择性去龋治疗的患牙41例,根据研究标准进行化学-机械去龋,去龋至韧化牙本质（SRFD组）和去龋至软化牙本质（SRSD组）并记录,行一步法充填。术后随访6个月,观察分析患牙牙髓活力、继发龋、充填物边缘完整性、表面状态、边缘变色情况及冷诊反应。结果两组患者术后6个月充填物边缘完整性、边缘变色情况、表面状态、继发龋情况、冷诊反应、牙髓活力差异无统计学意义（P>0.05）。SRSD组术后3个月与术后6个月的牙髓冷诊反应有显著差异（P<0.05）。结论深龋患牙采用化学-机械法去龋,不同去腐止点的窝洞,术后6个月治疗效果无显著差异。术后6个月,牙体与修复体相邻处指标无显著差异,去腐止点对牙髓电活力值影响无显著差异,去龋达软化牙本质对牙髓冷诊反应的影响可能在6个月及以上发生。

Abstract: PURPOSE: To observe the effect of different endpoints in chemical-mechanical caries removal for deep caries on the labial-buccal surface, and to provide reference for the selection of treatment methods and indications. METHODS: A total of 41 teeth diagnosed with deep caries and undergoing selective caries removal treatment were selected. According to the study criteria, chemical- mechanical decayed dentin, decayed dentin to toughened dentin (SRFD group) and decayed dentin to softened dentin(SRSD group) were recorded, and one-step filling was performed. The pulp activity, secondary caries, edge integrity, surface status, edge discoloration and cold irritation response of the affected tooth were observed and analyzed after 6 months. RESULTS: There was no significant difference between the two groups in the edge integrity, edge discolorimetry, surface status, secondary caries, cold irritation response and pulp activity 6 months after surgery(P>0.05). There was significant difference between 3 months and 6 months after operation in the SRSD group (P<0.05). CONCLUSIONS: There is no significant difference in the therapeutic effect of deep caries teeth treated by chemical-mechanical caries removal at different caries removal endpoints after 6 months of treatment, and there is no significant difference in the effect of decay endpoints on pulp electrical activity values. The effect of softening dentin by caries removal on pulp cold irritation response may occur at 6 months or more.
