Étude rétrospective sur l’efficacité du peroxyde d’hydrogène dans les pulpotomies de molaires primaires
Purpose: The objective of this retrospective study was to evaluate the clinical and radiological success of 3% hydrogen peroxide in primary molar pulpotomies and compare them to pulpotomies made with a 1:5 dilution of Buckley’s formocresol formula.  Methods: Clinical and radiographic data of 401 pulpotomized primary molars with a minimum follow-up of 24 months, except in cases of failure, were obtained from the records of 216 children.  Results: No statistically significant difference was observed between the results of formocresol and hydrogen peroxide pulpotomies clinically (p = 0.435) and radiologically (p = 0.2447). The cumulative probability of clinical survival was greater than or equal to 98% for molars treated with formocresol and 99% for those treated with hydrogen peroxide at all follow-up periods, ranging from 19 to 106 months. Radiologically, the cumulative probability of survival at 24 months was 81% for formocresol and 91% hydrogen peroxide.  Conclusion: Hydrogen peroxide has demonstrated clinical and radiological success rates comparable to those of formocresol in primary molar pulpotomies
