Abstract
In cases of fractured young permanent incisors after acute trauma, it seems important to allow physiologic root formation to continue. Pulpotomy with calcium hydroxide is considered to be one of the first choises in such cases. Therefore we observed the prognosis of 40 teeth which were treated with pulpotomy due to the clinical conditions and root development stages.
The results are summarized as follows.
1) According to our criteria,33 teeth were evaluated“good”,7 teeth“poor”at each final recall time. Poor cases were found mostly in periods of observation under 2 years.
2) Dentin bridges were observed in 24 cases, all of them being considered good cases.
3) The longer were the period between tooth fracture and treatment time, especially after 3 days, the higher were the percentage of poor cases.
4) There was little correlation between the condition of tooth fracture and its prognosis.
5) We observed root elongation or completion in over half of the cases, and estimated that this procedure had achieved its original purpose.
