Abstract

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.
