Objective: To study the curative effect of pulpotomy in the treatment of deciduous teeth with deep caries.
Methods: 45 deciduous molars with deep caries from 3 8 years old children were selected at random. Pulpotomy was performed on these treated teeth. Clinical examination and X-ray films for the treated teeth were taken to follow up all the teeth at 6 months, one year and two years respectively after treatment.
Results: At one year after treatment, 45 cases were followed up, the rate of success in clinical examination and in X-ray photographs both were 100%. While at two years after treatment, 42 cases were followed up and 3 cases were lost, the rate of success in clinical examination was 95% and the rate of success in X-ray photographs was 88%. The reasons of the failure were internal absorption and pulpitis followed by fracture and exfoliation of the obturators in the treated teeth.
Conclusion: Pulpotomy in deciduous teeth with deep caries was a reliable and effective method. It is necessary to follow up the treated teeth by X-ray at regular intervals after treatment.
