[Clinical and histological examination of young permanent teeth after vital amputation of the pulp]

Nowadays the vital pulpotomy is applied as the most biological therapy method in the therapy of complicated fractures of young permanent teeth. When the process of apexogenesis and apexification is completed, the extirpation of the radicular pulp is recommended, as there are doubts that degenerative and pathological changes might have occurred in the very pulp. The aim of this research was to histologically analyse the pulp of such teeth. To this purpose thirteen samples of human pulp, which were extirpated from clinically healthy teeth, were analysed; these teeth were successfully treated by means of vital amputation. The results showed that within these pulps there were no changes such as inflamed cells, calcification, changes in the number of cells and in the amount of collagen fibres, to a much greater extent than what would be found in intact teeth or in teeth treated conservatively. From the above we can draw conclusions, as well as use it as guidance in practical work: in cases of successful therapy of fractured young permanent teeth the vital extirpation of the pulp as preventive measure is not justified. Such a tooth has to be watched clinically and radiographically throughout a longer period of time.
