A split-mouth randomized controlled trial evaluated partial versus full pulpotomy using mineral trioxide aggregate in children aged 4–8 years with deeply carious primary molars requiring pulpotomy. The study enrolled 60 pair-matched molars in 27 children, with clinical and radiographic assessments over 12 months. Clinical success rates were 96.6% with partial pulpotomy and 93.1% with full pulpotomy, while radiographic success rates were 89.7% and 86.2%, respectively.

Neither comparison showed a statistically significant difference (P>.05). In the partial pulpotomy group, second primary molars had a significantly higher success rate than first primary molars (100% vs 72.7%; P=.045).Partial pulpotomy is a minimally invasive approach that may support pulpal healing and repair, offering a more conservative option for vital pulp therapy in primary teeth. Partial pulpotomy using mineral…
