Pulpectomy success with iodoform/calcium hydroxide in pediatric primary molars: a retrospective survival analysis.

This article focuses on the clinical success and survival of pulpectomy in pediatric primary molars using iodoform/calcium hydroxide [iodoform/Ca(OH)₂] paste, analyzed through a retrospective cohort study with time-to-event methodology. Reviewing 167 primary molars with at least six months of follow-up, the study found high short- to medium-term success rates that gradually declined over time, with immediate placement of stainless-steel crowns and treatment of second primary molars—especially mandibular second molars—being significantly associated with improved survival. In contrast, obturation quality and preoperative clinical or radiographic signs showed no significant impact on treatment outcomes. The findings support the use of iodoform/Ca(OH)₂ paste as a viable obturating material in pediatric pulpectomy when combined with appropriate restorative protocols, while emphasizing the importance of procedural and tooth-related factors over radiographic obturation characteristics.
