(PR02) Outcome of Vital Pulp Therapy Using Calcium Silicate-Based Materials in Immature Permenent Teeth: A Retrospective Cohort Study

Abstract:

Introduction: The purpose of vital pulp therapy is to maintain pulp viability by eliminating bacteria from the dentin-pulp complex and to establish an environment in which apexogenesis can occur. The aim of this retrospective cohort study was to evaluate the clinical and radiographic outcomes of vital pulp therapy on immature permanent teeth using different calcium silicate-based materials.

Methods: This study was carried out in the Virginia Commonwealth University Graduate Endodontics department in Richmond, Virginia. Vital pulp therapy cases performed by graduate endodontic residents were retrospectively searched and charts were reviewed to determine inclusion into this study. All cases selected for this study were vital pulp therapy treatments performed on immature permanent teeth using a calcium silicate-based material. The treatment outcomes were assessed clinically and radiographically at a minimum of 6 months post-treatment. Three endodontists and 3 endodontic residents were selected to assess the pre- and post-treatment radiographs. The examiners were calibrated and used Ortavik’s PAI to assess periapical healing.

Results: One hundred fifty charts met the inclusion criteria and were included in this study. The study showed a survival rate of 99% and a success rate of 94%. Dental sensitivity to cold reported by patients reduced over time, radiographic outcomes showed an increase in apical dentin deposition, and all immature teeth showed continued root formation.

Conclusions: Vital pulp therapy on immature permanent teeth using calcium silicate-based materials is a viable treatment option for treating teeth affected by traumatic or carious exposures of a vital pulp.
