The aim of this study was to compare the outcomes of pulpotomy treatment using calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA) in carious-exposed vital immature permanent first molars.
Participants (n=51, 1 tooth per patient) with immature molars with clinical carious exposure with symptomatic/asymptomatic pulpitis were randomised to undergo pulpotomy using either CEM (n=26) cement or MTA (n=25). After performing pulpotomy and covering the radicular pulps with the biomaterials, all teeth were permanently restored. Clinical and radiographic evaluations were performed at 6 and 12 months after operation for signs of success or failure. Radiographs being evaluated for complete/partial apical closure.
The patients were aged between 6- 10 years old. ( mean = 8.30). 49 participants were available for assessment a 12 months.
- No significant difference at the baseline between the two groups.
- All 49 teeth showed pulp survival and signs of continuous root development after 12 months.
- No statistical difference in terms of radiographic outcomes between two groups.
- Complete apical closure (apexogenesis) occurred in 76.8% of the CEM group and 73.8% of MTA group.
The authors concluded
Calcium-enriched mixture cement and MTA showed similar performance in pulpotomy of immature caries-exposed permanent molars.
