Abstract: ［Abstract］〓Objective〖HTSS〗〓To investigate the application effect of bioceramic iroot bp PLUS on patients with localized acute pulpitis undergoing vital pulp preservation.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 192 offending teeth of 110 patients with pulpitis were selected. According to the simple random method, they were divided into observation group and control group, 96 in each group. The control group was coated with calcium hydroxide paste, and the observation group was treated with bioceramic iroot bp PLUS for coronary resection.The efficacy, the restoration of the affected tooth and satisfaction of the two groups were observed and compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The clinical efficacy of the observation group was better than that of the control group on the first day and the seventh day(P＜005). There was no significant difference in the clinical efficacy between the two groups at 3 months(P＞005).The pain level of further consultation of the observation group was significantly better than that of the control group(P＜005). The gingival condition, secondary caries and tooth fracture in the observation group were better than in the control group(P＜005). There was no significant difference in edge staining, marginal integrity and prosthesis fracture between the two groups(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The bioceramic iroot bp PLUS has better filling effect in patients with localized acute pulpitis who undergoing pulp preservation, and the tooth defect can achieve satisfactory repair effect and the pain recovery is better, which is worthy of clinical promotion.
