Evaluation of two conservative different treatment protocols for symptomatic proximal deep caries management in molar teeth; an 18-month clinical report

[摘要] Aim:  The primary aim of this clinical trial was to observe the clinical success in conservative management of symptomatic deep proximal caries in permanent molar teeth with two treatment pulpotomy with Biodentine and indirect pulp capping with calcium hydroxide. Materials and Methods:  A total of 71 patients who reported to department for the management of symptomatic proximal deep carious lesions in molar teeth participated in the trial. Posttreatment clinical success at 18 months was defined as asymptomatic teeth positively responding to cold pulp sensibility test (only in indirect pulp capping) and absence of periapical infection. Chi-squared test and Kaplan–Meier survival analysis were done. Results:  Chi-squared test revealed no significant association between pulp status and posttreatment follow-up in both the treatment groups. Kaplan–Meier survival analysis showed mean survival of pulpotomy procedure for moderate and ambiguous pulp as 66.16 and 67.77 weeks, respectively, with no significant difference for two different pulp statuses. In indirect pulp capping procedure, there was significant difference (P = 0.038) (Log-rank Mantel-Cox) between the two pulp status category with moderate pulpitis having mean survival period of 69.27 weeks and ambiguous pulp with 42.83 weeks. Conclusion:  Pulpotomy with Biodentine yielded better results than compared to indirect pulp capping.
