It has been reported that the operative treatment for the preservation of tooth having periapical lesion has shown over ninety percent of success whereas in the case where calcified canal is severe, canal is perforated, ledge is formed, tooth restored by post and core and cases where symptoms still exist after treatment, endodontic treatment may not all be the solution in attaining a successful treatment. Thus Apicoectomy would generally be used to prevent the loss of tooth having periapical lesion where treatment prognosis is poorly evaluated by endodontic treatment. In case 1 and 2, endodontic treatment was applied due to unilocular radiolucent lesion in periapical area but the symptoms somehow did not show improvement and therefore operated apicoectomy, and as in case 1, favorable results were attained but as in case 2, yet more observation has to be done. The followings are the results we have concluded : 1. In the process of endodontic treatment, absolute canal obturation has great effect on attaining successful treatment. 2. In cases where endodontic treatment is not highly recommended, for example, tooth having dental pulp and periapical lesion, favorable results can be attained by applying apicoectomy.

Two case reports describing a new technique of creating a repositionable piezoelectric bony window osteotomy during apicoectomy in order to preserve bone and act as an autologous graft for the surgical site are described. Endodontic microsurgery of anterior teeth with an intact cortical plate and large periapical lesion generally involves removal of a significant amount of healthy bone in order to enucleate the diseased tissue and manage root ends. In the reported cases, apicoectomy was performed on the lateral incisors of two patients. A piezoelectric device was used to create and elevate a bony window at the surgical site, instead of drilling and destroying bone while making an osteotomy with conventional burs. Routine microsurgical procedures - lesion enucleation, root-end resection, and filling - were carried out through this window preparation. The bony window was repositioned to the original site and the soft tissue sutured. The cases were re-evaluated clinically and radiographically after a period of 12 - 24 months. At follow-up, radiographic healing was observed. No additional grafting material was needed despite the extent of the lesions. The indication for this procedure is when teeth present with an intact or near-intact buccal cortical plate and a large apical lesion to preserve the bone and use it as an autologous graft.

본 논문에서는 치조골의 흡수 유형에 따른 치근단 절제술의 수술적 평가를 수행하였다. 유한요소해석이 사용되었으며 CT 이미지를 통하여 동양 성인 여성의 상악 중절치의 3D 모델을 사용하였다. 연구에는 상악중절치의 정상저작하중조건이 적용되었다. 치조골 흡수 유형에 따른 치근 절제술의 평가를 위해 정상모델과 함께 치조골의 전체적 흡수 모델, 순측 흡수 모델 및 설측 흡수 모델을 비교하였다. 이에 따라 설측 치조골 흡수의 영향은 순측 치조골의 흡수에 비해 치아의 유지 안정성에 미치는 영향이 작음을 확인하고, 설측 치조골 흡수로 인해 치근이 노출된 환자를 대상으로 한 치근 절제술의 위험 가능성을 제시하였다.

A 10-year-old, female mixed breed dog and a 3-year-old, female chihuahua which had swelling below lower eyelid were refered to Veterinary Medical Teaching Hospital, Seoul National University. The plain maxillary oblique view revealed radiolucency at periapical area in maxillary fourth premolar. The 2 cases were diagnosed as periapical abscess by clinical sign and radiographs, and apicoectomies were performed for resetting the lesions and preserving the teeth. Under general anesthesia with isoflurane, periapical abscess was resected by burs and the defect was filled with zinc phosphate cement. Radiograph was perfomed at 1 week and 1 year after apicoectomy and there was no evidence of recurrence.

The apicoectomy is an operation in which the root apex is removed and the adjacent periapical pathologic tissue is curetted. In this operation, there are several factors that may lead to the surgical wound infection, such as, local, systemic, environmental, endogenous and surgical factor. The systemic medical and surgical factor that may compromise patients defense are more important cause of the wound infection. The postoperative infection is likely to occur owing to poor systemic condition(especially geriatric cancer patient with operation, radiotherapy and chemotherapy), postoperative accumulation of hematoma & seroma and other contaminated factors. So, the authors established the immediate rubber drainage into the sutured wound of dental apicoectomy for the prevention of postoperative infection. The results are more favorable without the wound infection in total 31 cases of the dentistry of Dong San Medical Center & Wonju Christian Hospital.

연구목적: 본 연구는 치근단절제술과 역충전을 시행한 환자를 대상으로 치근단미세수술의 결과에 대한 환자의 인식과 만족도를 조사하는 것을 목적으로 하였다. 연구 재료 및 방법: 연세대학교 치과보존과에서 치근단 수술 후 최소 3개월 이후 정기검진을 위해 내원한 환자를 대상으로 설문조사를 시행하였다. 응답자의 나이/성별간 응답의 차이가 있는지는 contingency table을 이용해서 분석하였다 (p=0.05). 결과: 응답자의 60% 정도가 이전에 치근단 수술에 대해서 들어본 적이 없었으며 치근단 수술을 결정한 이유는 63.3%에서 자연치를 보존하기 위해서라고 응답하였다. 이후 비슷한 상황이 생긴다면 대부분의 환자가 다시 치근단수술을 선택할 것이라고 하였으며 수술의 만족도는 전반적으로 높은 편이었다. 결론: 치근단수술은 대부분의 환자에서 만족스러운 치료로 인식되고 있다.
