简要总结
The study compares the prognosis of cases of Separated Instruments in Canals With Type II Vertucci's Classification treated with conservative approach
详细描述
Teeth with Type II Vertucci root canal configuration are having more incidence of instruments separation due the presence of an S-type (Double curve). The aim of this study is to compare the outcome of minimally invasive approach (MIA), retaining the separated in one root canal, cleaning and shaping of portals of entry of the two canals and portal of exit of both canals through the other patent canal, in comparison to the outcome of retrieval of the broken instrument by ultrasonics retrieval techniques (URT)

结局指标
主要结局
monitoring of periapical index
时间窗: 2 years
The peri-radicular condition was evaluated using the Periapical Index (PAI) created by Ørstavik et al. (1986). The PAI includes five grades represented on an ordinal scale as follows: (1) normal periapical structures; (2) small changes in the periapical bone or bone structure; (3) changes in the periapical bone structure with mineral loss, characteristic of apical periodontitis; (4) demineralization of the periapical bone within a well-defined radiolucent area; and (5) demineralization of the periapical bone with exacerbations and expansion in bone structure.
