(PR80) Evaluation of Vital Pulp Therapy Using Bioactive Endodontic Cements in Immature Permanent Teeth: A Retrospective Study

Abstract:

Introduction: Apexogenesis of immature permanent teeth with a pulpal pathosis allows for the maintenance of vital pulp in order for root development to continue and ultimately result in apical closure. This study aims to compare the outcomes of using calcium silicate-based, bioactive root canal cements, namely ProRoot MTA (Dentsplly Tulsa Dental Specialties, Johnson City, TN, USA), Biodentine (Septodont, Saint-Maur-des-Fosses Cedex, France), and EndoSequence BC RRM-Fast Set Putty (Brasseler, Savannah, GA, USA) as well as calcium hydroxide in vital pulp therapy for the purpose of apexogenesis.

Methods: This retrospective study used data that was collected from electronic health records of patients of Rutgers School of Dental Medicine who were treated with direct pulp caps and pulpotomies between 07/01/2015 to 07/01/2021 and returned for recall appointments between 3 and 64 months afterwards (n=66). The success of treatment, as determined by the lack of clinical signs and symptoms and lack of radiographic interpretation of periapical pathosis, as well as the continued development of dentin were assessed.

Results: The overall clinical success of vital pulp therapy was 66.7% and the continued dentin development using all four materials was 78.8%. The difference in the type of material placed, including calcium hydroxide, was found not to be statistically significant (p <.05).

Conclusions: Vital pulp therapy is a viable procedure for the purpose of apexogenesis for further development of the root apex in immature permanent teeth with all materials studied. Further research is necessary to determine its long-term success.
