Clinical observation of vital pulpotomy in primary teeth with different pulp capping materials

Objective To observe the effectiveness of vital pulpotomy with mineral trioxide aggregate(MTA) and glutaraldehyde during the treatment of primary teeth.Methods 80 deciduous molars with deep caries from 4-8 year-old children were selected.All selected teeth were randomly divided into control group(using glutaraldehyde pulpotomy) and experimental group(using MTA pulpotomy).Patients were recalled for clinical and radiographic evaluation in 6-month,one-year and two-years periods.Results 6 months after the treatment,the rates of success in both groups were close,but after one year and two years,the rate of success in experimental group was higher than that in control group.There was statistically significant difference in the success rate of teeth treated with MTA pulpotomy in comparison to those treated with glutaraldehyde pulpotomy﹙P0.05﹚.Conclusions The clinical effectiveness of vital pulpotomy in primary teeth with MTA is better than that with glutaraldehyde.
