# Evaluation of iRoot BP Plus for Pulpotomy in Permanent Anterior Teeth With Complicated Crown Fractures in Pediatric Patients: A Prospective Cohort Study

## TL;DR

This study shows that pulpotomy with iRoot BP Plus is highly effective for treating fractured permanent front teeth in children.

## Contribution

The study provides new clinical evidence on the long-term success of iRoot BP Plus for pulpotomy in pediatric dental trauma.

## Key findings

- Success rates were 95.2% at 6 months and 90.9% at 12 months.
- The 2-year survival rate was estimated at 94.7%.
- Success was not affected by factors like root maturation or tooth mobility.

## Abstract

This study aims to assess the effectiveness of pulpotomy in treating permanent anterior teeth with complicated crown fractures in children. Additionally, it seeks to analyze the long-term outcomes to inform clinical practices for dental trauma across a wider age spectrum.

A total of 126 permanent incisors in 107 patients, aged 7–15 years, diagnosed with complicated crown fractures, were treated with pulpotomy using iRoot BP Plus as the pulp capping agent. The treated teeth underwent clinical assessments at 6–8 weeks, 3 months, 6 months, and 1 year post-treatment, followed by routine oral examinations. Outcomes were determined based on clinical and radiographic criteria assessed by calibrated examiners. Clinical examinations included assessment of root apex formation, mobility, crown color, pulp vitality test, and the presence of abscesses and fistulas. Radiographic examinations included evaluation of periodontal ligament continuity, periapical translucency, dentin bridge formation, and calcification of the pulp chamber and root canal.

With an average follow-up of 14.1 ± 12.6 months, success rates of 95.2% at 6 months and 90.9% at 12 months were observed. The estimated 2-year survival rate was 94.7% ± 2.7%. Success was independent of factors like gender, root maturation, pulpotomy type, pulp exposure time, and tooth mobility. Seven failures were noted, primarily due to periapical periodontitis. One case of pulp canal obliteration was observed.

Pulpotomy using iRoot BP Plus shows a high success rate in children with nondisplaced complicated crown fractures in permanent teeth. The prognosis is unaffected by root apex formation or tooth mobility.
