[Introduction of a new technique of partial pulp amputation in permanent teeth in children after mechanical injuries....

The study material comprised 56 permanent teeth with traumatic pulp exposure complicated in 15 cases by partial tooth luxation in 52 children aged from 7 to 15 years. In each case routine clinical and radiological examinations were done. The time between trauma and procedure ranged from several hours to 70 days. In all teeth partial pulp amputation was done cutting off by the gentle technique a part of the coronal pulp and covering of the remaining pulp with calcium hydroxide, zinc oxide with eugenol or with Dycal, carboxyl cement and permanent filling. The analysis of the studied material showed that the greatest group comprised children aged 8-11 years (40 cases), and fractures of one-half of the crown prevailed (32 cases), point pulp exposure (32 cases), developmental stage Rc and A 1/2 of root (40 cases). The short-lasting follow-up made possible clinical and radiological control of only 39 teeth after 6 months, and 7 teeth after 12 months. After 6 months good results were obtained in 84.6% of cases.
