Evaluation of clinical efficacy of partial pulp cutting for caries exposed young permanent teeth with mineral trioxide aggregate.

Objective To investigate the clinical effect of partial pulp cutting for caries exposed young permanent teeth with mineral trioxide aggregate(MTA).Methods Eighty young permanent teeth partial pulpotomy patients admitted to the Foshan First People's Hospital from January 2019 to January 2021were prospectively selected as the research objects,and divided into observation group(MTA pulp capping)and the control group(Dycal calcium hydroxide)in the two groups according to the random number method,40 cases in each group.Six months of observation,treatment-related indicators of the two groups of patients were compared,changes in inflammatory factor levels were detected,the length of tooth root,the success rate of treatment and the incidence of postoperative complications were followed up before and 3 and 6 months after operation.Results The average number of times and average period of treatment in the observation group were(3.05±0.64)times and(0.65±0.15)months,which were shorter than those in the control group[(3.05±0.64)times,(4.26±1.16)months],and the differences were statistically significant(P<0.05).Before operation,there was no significant difference in the levels of inflammation indexes between the two groups of patients(P>0.05);after the operation,the levels of interleukin(IL)-1β,IL-6,tumor necrosis factor alpha(TNF-α)in the observation group were(13.25±2.54),(1.02±0.25),(2.37±0.44)μg/L,which were significantly lower than those in the control group[(17.29±2.15),(1.54±0.32),(3.66±0.54)μg/L],the differences were statistically significant(P<0.05).There was no significant difference in root length between the two groups before operation(P>0.05);3 and 6 months after operation,the root length of the observation group was(15.45±1.63)and(16.12±0.42)mm,which were significantly longer than those of the control group[(14.54±1.40),(15.21±0.27)mm],the difference was statistically significant(P<0.05).The treatment success rate(95.0%)of the observation group at 6 months after operation was significantly higher than that of the control group(75.0%),and the difference was statistically significant(P<0.05);the observation group's complication rate(5.0%)was significantly lower than that of the control group(20.0%),the difference was statistically significant(P<0.05).Conclusion MTA in caries exposed young permanent teeth partial pulp incision,is beneficial to reduce inflammation,improve root length,treatment times and cycles,reliable effect,fewer complications,worthy of clinical application.
