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

牙髓治疗的概念是近二三十年来在生物学研究的科学背景下形成的。然而，新旧牙髓学科在诊断、病例选择、根管流出物的评价、根管间隙的成败及其随访研究等方面存在一些混乱。本研究的目的是建立一个标准概念，由17个牙髓学权威机构在每个子标题下按照不同的特殊领域收费。(L)在X线不透明的情况下进行随访研究。(2)不同年龄、不同牙位的牙髓病变发生率。(3)牙髓切断术及根尖周病的远期随访研究。(4)根管标本的细菌学和免疫学检查。(5)根管出液分析及随访研究。(6)防腐剂和氢氧化钙作为根管药物的临床评价。(7)根管间隙对根管充填成败的影响。(8)钙化物根管未打补术的随访研究。(9)根管内治疗与根管外科治疗的对比研究。(10)根管治疗的禁忌症及其原因分析。(11)全科医生和牙髓治疗专科医生的成功率。

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.
