Abstract
|
|
|
When a permanent tooth with underdeveloped root undergoes pathologic changes in the pulp, calcium hydroxide apexogenesis or apexification might be the choice of treatment depending on the condition of pulpal vitality. As a rule, when the pulp is vital, calcium hydroxide apexogenesis can be performed, while the pulp is non-vital, apexification is the choice. However, the choice between two different treatment modality should be decided judicially. Because the results obtained from the two treatment procedures are absolutely different. With a calcium hydroxide pulpotomy, the underdeveloped root will proceed a physiologic root formation and therefore an elongation of root length can be achieved. On the other hand, with the calcium hydroxide apexification, the root will develop a cementum-like hard tissue at the site, thereafter the length of root can not be increased.
Two cases, those were erupted too early without root formation, suffered from acute pulpitis due to retrograde infection, and also represented severe mobility and pain. Calcium hydroxide pexogenesis was performed on these cases, and the results were turned out to be encouraging. The results were as follows: 1. HERS(Hertwig's Epithelial Root Sheath) of prematurely erupted permanant tooth with under-developed root formation may still maintain a vital activity, even though the vitality of the pulp tissue has gone through a necrotic changes due to retrograde infection. 2. Calcium hydroxide apexogenesis, that can bring a physiologic root formation, might be the choice of treatment.
