The Survey Study of the Incidence their Analysis in the Success Rate.

根管治疗的概念是近二、三十年来在生物学研究的科学背景下建立起来的。然而，根管治疗学在诊断、病例选择、根管延长的评价、根管间隙的成败及随访研究等方面，在新旧两个学科中存在着一些混乱，本研究的目的是建立一个标准的概念，以解决这些问题。(l)通过X线不透射线的存在进行随访研究。(2)根管病变的发病率与年龄和牙位的关系。(3)活髓切断术合并根尖周病变病例的长期随访研究。(4)根管治疗个体的细菌学和免疫学检查。(5)根管延长的临床分析及随访研究。(6)防腐剂和氢氧化钙根管药物的临床评价。(7)根管充填的成功与失败与根管间隙的关系。(8)钙化根管与未开放根管的随访研究。(9)根管治疗与根管手术的比较研究。(10)根管治疗的禁忌症及其原因分析。(11)全科医生和专科医生在根管治疗中的成功率。

The concept of endodontic therapy is established duaring last two to three decade baced on scientific background of biological studies. However, there are some confusion in the old and new aspect of endodontic discipline, such as in diagnosis, case selections, the evaluation of root canal exdate, the success or failure by canal space, and their follow up studies.The porpose of this study is to establish the standard concepts to solve thies problems by a groupe of endodontic 17 authorities in each sub-titled following different special field charged. (l) Follow up study by the presence of X-ray radiopaque. (2) Incidence of endodontic lesion by the age and the tooth location. (3) Long term follow up study of the case of pulpotomy and periapical lesion. (4) Bacteriological and immunological examination of root canal individuals. (5) Analysis of the root canal exdate and its follow up study. (6) Clinical evaluation of antiseptics and calcium hydrooxide for rooot canal medicament. (7) Sucsess and failure of root canal fiuings by their canal space. (8) The follow up study of calcifide and not patend root canal. (9) Comparative study between intra canal treatment and endodontic surgery. (10) Contra indications of the endodontic treatment and their cause analysis. (11) Sucsess rate of GP and specialist in endodontic therapy.
