Clinical and Radiographic Success Rates of Pulpotomies in Primary Molars Treated with Formocresol, BiodentineTM, and Endo Repair: A Randomized Clinical Trial

ABSTRACT

ABSTRACT Objective: To compare the clinical and radiographic success rates of formocresol, BiodentineTM, and Endo Repair agents in primary molars after 12 months. Material and Methods: This randomized double-blind clinical trial was conducted on healthy children referred to the Department of Pediatric Dentistry, Kerman, Iran, in 2018. One hundred twenty children (human primary molar teeth) aged 3-9 years were selected and randomly divided into three interventions (with pulpotomy medicament agents), including formocresol, BiodentineTM, and Endo Repair. All pulpotomized teeth were restored using stainless steel crowns and evaluated clinically and radiographically during a 12-month follow-up. Fisher exact test was used to determine the association of categorical variables and the data were analysed with SPSS 25. Results: All the available teeth in formocresol and BiodentineTM groups obtained clinical success, whereas 62.5% of the Endo Repair group was successful in this regard. Radiographic success rates of the formocresol, BiodentineTM, and Endo Repair groups were 94.7%, 70%, and 28.1% after a 12-month follow-up, respectively. Moreover, pulp canal obliteration was observed in 26.3%, 25%, and 12.5% of the formocresol, BiodentineTM, and Endo Repair groups. Conclusion: This study reported a high rate of clinical success using both BiodentineTM and formocresol pulpotomy techniques. However, the radiographic success rate of formocresol was higher than that of BiodentineTM, and Endo Repair was not considered a suitable pulpotomy medicament agent.
