Abstract

Preserving the pulp is important in the treatment of carious pulp exposure in young permanent teeth. Pulpotomy is a vital pulp therapy in which a portion of the coronal pulp tissue is surgically removed, and the remaining radicular tissue is covered with suitable material that protects the pulp from further injury and permits and promotes healing. It is important to develop biocompatible treatment directed at maintaining pulp vitality and increasing tooth longevity. Platelet-rich fibrin (PRF) has been referred to as a second-generation platelet concentrate. Two clinical cases in which PRF was applied as a medicament after pulpotomy of an immature permanent tooth are presented. After isolation, caries removal and pulpotomy with PRF was performed. A layer of mineral trioxide aggregate (MTA) was placed over the PRF, and the final restoration was performed. Postoperatively, the patient had no pain or discomfort, and follow-up radiographs revealed normal periodontal ligament space and trabecular bone pattern.

심한 우식을 보이는 미성숙 영구치 치료에 있어서 치수생활력을 보존하는 것은 중요하다. 치수절단술을 시행 시 생체적합성이 있는 재료를 이용하여 치료함으로써 남아있는 생활력이 있는 치수를 보호하며 미성숙 영구치의 치근 성장을 도모할 수 있다. 혈소판 농축 섬유소는 환자의 혈액을 직접 채취하여 적용하기 때문에 생체적합성이 뛰어나며 다양한 성장인자를 함유하고 있어 치수생활력을 유지하고 미성숙 영구치의 치근 발육을 촉진시킬 수 있다. 본 증례에서는 심한 치아 우식증을 보이는 미성숙 영구치에서 치수절단술 시행 후 남아 있는 치수 상부에 혈소판 농축 섬유소를 적용하였다. 정기적인 검진 결과 미성숙 영구치의 치근 성장 및 정상적인 치아 주위 조직들이 관찰되었다. 향후 장기간의 임상적 관찰이 필요할 것이며 더 많은 임상 증례를 바탕으로 한 연구가 필요할 것이다.
