Formocresol pulpotomy in primary molars: a long-term radiographic evaluation.

Of 137 pulpotomies with Tempophore, 13 percent failed. In comparison with pulpotomies using Ca(OH)2, in which higher failure rates occurred (Magnusson, Schröder), we can conclude that the pulpotomy with Tempophore, as well as with Buckley's formocresol, can be considered a clinically successful therapy. These therapies permit the preservation of even extensively carious primary molars, until their normal exfoliation time. The preservation of these teeth prevents the appearance of functional as well as orthodontic problems, because the arch-length is not adversely affected. The mesial tipping or drifting of the permanent molars is, furthermore, prevented.
