RESUMEN
This retrospective chart review study investigates the long-term clinical outcome of Biodentine® (Tricalcium silicate) as a medicament for pulpotomy in primary molars. Data in this retrospective study was collected from the dental records of all patients that had at least one primary molar receive pulpotomy treatment (CDT code: D3221) between 01 July 2012 and 01 July 2015. This data includes child's age, medical history, dental history, dental radiographs, pulpotomy procedure details and follow-up clinical notes. Kaplan-Meier Estimate was used to measure the fraction of successful pulpotomy procedures for up to 24 months. A total of 1758 pulpotomy procedures were performed on 1032 patients in our institute in the three-year period and 21.4% of them (N = 376) had follow-up dental records that qualified for the study. Eleven teeth out of 376 teeth were excluded from the statistical analysis due to loss of/broken stainless steel crowns (3.1%). Seventeen pulpotomy failures were identified out of the remaining 365 procedures. The survival probablity of using Biodentine® as a pulpotomy medicament is 96.3% for 18-month follow-up and 95.4% for 24-month follow-up. Biodentine®, a tricalcium silicate formulation, used as a pulpotomy medicament demonstrates a high clinical success rate (95.4%) over a 24-month peroid in primary molars.
