Description
Satimanon and four co-authors tracked how long treated baby molars survive in twenty twenty-six. Pulpectomy, a root canal for primary teeth, is used when infection reaches the tooth's tip. Long-term survival data for infected primary molars were scarce, so the team reviewed records at a Thai university clinic.
Three hundred twenty-six molars from two hundred forty-two children aged three to six were followed. About fourteen percent failed. Survival was perfect at one year and about ninety-five percent at two years, but fell to roughly fifty-two percent by four years. A preoperative sinus tract, a small drainage channel, was the most consistent failure predictor, raising risk about fivefold. Older age and advanced root resorption also raised risk in the main analysis. Treatment details like visit count or filling material did not matter.
