简要总结
The aim of study was to evaluate the effect of dental operating microscope use on the healing outcome of non surgical endodontic treatment of maxillary molars.
详细描述
Prior to treatment a thorough clinical and radiological examination was carried out. A thorough history was taken from each patient and written informed consent was taken after explaining the procedure, risks and benefits. Mature maxillary first permanent molar with diagnosis of periapical periodontitis (as confirmed clinically & by periapical radiograph) was chosen for the study. Fifty participants were randomly assigned to either the dental operating microscope group or to control group (without using dental operating microscope) for the treatment.
After administration of local anesthesia and rubber dam isolation of the involved tooth ; access cavity was prepared using carbide bur and refined using ultrasonic tip in both groups. In both the groups similar protocol for irrigation, obturation and post operative restorations was followed. Immediate post-operative radiograph was taken using preset exposure parameters and follow up clinical and radiographic examination was carried at 12th month.

结局指标
主要结局
Clinical and radiographic success
时间窗: 12 months
long term clinical and radiographic success measured in terms of reduction in size of periapical radiolucency on radiograph from baseline to 12 months using PAI score 1,2 as healing and more than 2 as non healing
次要结局
- Number of canals located in MB root(12 months)
