Abstract：Objective To analyze the clinical effect and safety of the treatment of pulp necrosis(PN)with the retentive superinlays.Methods A total of 80 patients with PN who received treatment in Fujian Medical University Affiliated Mindong Hospital from January 2020 to June 2023 were selected and divided into a control group(cast porcelain crown repair treatment)and an observation group(pulp cavity retention superinset repair treatment)according to the treatment plan,with 40 cases in each group.The repair effect and safety of the two groups were compared.Results At 7 d and 10 months after treatment,the excellent and good repair rates in the observation group were 95.00%and 92.50%,respectively,while those in the control group were 92.50%and 75.00%,respectively,and the differences were statistically significant(P<0.05).After 10 months of treatment,the incidence of adverse prognosis was 7.50%in the observation group and 25.00%in the control group,the difference was statistically significant(P<0.05).Compared with the control group,the gingival index and plaque index of the observation group were lower at 7 d and 10 months after repair,and the score of repair effect was higher,with statistical significance(P<0.05).Conclusion The treatment of PN by selecting the medullary cavity retention superinput repair scheme can ensure the repair effect,maintain the periodontal health,maintain the long-term effect and avoid the occurrence of adverse prognosis.
