Clinical Trial Summary

Pediatric dentists frequently encounter deeply carious young permanent first molars (PFM) with Molar Incisor Hypomineralisation (MIH). Pulpal status of affected PFM was found to be different from that of unaffected PFMs which consequently might influence the pulpal response after vital pulp therapy.

The aim of this study is to evaluate the clinical and radiographic effectiveness of partial removal of pulp in deeply carious symptomatic PFM affected with MIH over 24 months.

Description:

Pediatric dentists frequently encounter deeply carious young permanent first molars (PFM) with Molar Incisor Hypomineralisation (MIH). Pulpal status of affected PFM was found to be different from that of unaffected PFMs which consequently might influence the pulpal response after vital pulp therapy. The aim of this study is to evaluate the clinical and radiographic effectiveness of partial removal of pulp in deeply carious symptomatic PFM affected with MIH over 24 months. In this prospective randomized controlled clinical trial, a randomized assigned sample of 96 children each with a deeply carious young PFM, Group I (n=48) diagnosed with MIH and irreversible pulpitis and Group II (n=48) diagnosed with irreversible pulpitis but not affected with MIH. Group I will be randomly equally allocated into Group II A (n=24): partial pulpotomy (PP) and Group I B (n=24): full pulpotomy (FP). Group II will also be randomly equally allocated into Group II A (n=24): PP and Group II B (n=24): FP. If pulpal bleeding cannot be controlled within 6 minutes using cotton pellets soaked in 3% sodium hypochlorite, the allocated procedure will be abandoned. The pulpotomy agent to be used will be mineral trioxide aggregate (MTA) and teeth will be restored using a resin modified glass ionomer restoration (RMGIC). Teeth will be followed up clinically and radiographically using periapical x-rays for 24 months. Cone beam computed tomographic scans will be taken initially and at 24 months. Pain levels will be scored preoperatively before local anesthetic administration and postoperatively every 24 hours for 7 days using visual analogue scale. All data will be statistically analyzed and discussed considering the results obtained.

• No pulp exposure after caries excavation.

Intervention

Procedure:
• Vital Pulp Therapy
The pulp is accessed after caries removal then the inflamed part of the pulp is excavated. After haemostasis is achieved, a pulpootmy medicament is used to coronally seal the remaining pulp tissue. In partial pulpotomy only part of the pulp chamber is excavated while in full pulpotomy the whole pulp chamber is excavated.
