Clinical and radiographic comparison of primary molars after formocresol and electrosurgical pulpotomy: a randomized clinical trial.
BACKGROUND
Vital pulpotomy is a single-stage procedure defined as the surgical amputation of the coronal portion of exposed vital pulp, usually as a means of preserving the vitality and function of the remaining radicular portion.


OBJECTIVE
The aim of this study was to compare the clinical and radiographic success rates for electrosurgical vs formocresol pulpotomy in human primary molar teeth.


METHODS
This was a prospective, randomized clinical trial.


METHODS
In this randomized clinical trial, pulpotomies were performed on 70 primary molars in children aged 5-10 years. The teeth were treated using either a conventional formocresol (35 teeth) or electrosurgical technique (35 teeth). Following the pulpotomy procedure, the teeth were evaluated for clinical and radiographic success for three, six and nine months. The teeth were evaluated for the presence of pain, abscess, fistula, mobility, internal and external resorption, and radiolucency.


METHODS
The data were assessed with Fishers' Exact test.


RESULTS
After nine months of follow-up, the clinical and radiographic success rates were 96 and 84% respectively in the electrosurgical group and 100 and 96.8% respectively in the formocresol group. There was no statistically significant difference between the success rates in the two groups ( P > 0.05).


CONCLUSIONS
Our results showed the failure rates for electrosurgical pulpotomy to be equal to those for formocresol pulpotomy. Although electrosurgical pulpotomy is a nonpharmacological technique giving favorable results, it is still a preservative technique. Further studies using larger samples and longer evaluation periods are recommended.
