Resumen
Objectives: This retrospective cohort study evaluated the clinical success of pulpectomy in pediatric primary molars using iodoform/calcium hydroxide [iodoform/Ca(OH)2] paste, and examined procedural and tooth-related factors associated with treatment outcomes over time.
Method and materials: Records of pediatric patients treated with pulpectomy using iodoform/Ca(OH)2 paste were retrospectively reviewed. Of 1,831 screened records, 167 primary molars that met the inclusion criteria and had a minimum follow-up of 6 months were included in the final analysis. Clinical and radiographic outcomes were assessed longitudinally. Treatment success was analyzed using Kaplan–Meier survival analysis, and factors associated with failure were explored using Cox proportional hazards regression.
Results: Overall clinical success was high, with favorable short- to medium-term outcomes and a gradual decline in survival over time. Immediate placement of stainless-steel crowns was significantly associated with improved treatment survival (P = .046), as was tooth type, with second primary molars showing superior outcomes (P = .024). In contrast, obturation quality and preoperative clinical signs were not significantly associated with treatment failure (P > .05).
Conclusion: Pulpectomy of primary molars using iodoform/Ca(OH)2 paste demonstrates reliable clinical performance in pediatric patients. Procedural and restorative factors, particularly immediate full-coverage restoration, appear to have a greater influence on long-term outcomes than radiographic obturation characteristics, supporting the material’s continued use in pediatric endodontic practice.
