简要总结
Aim: To evaluate and compare the outcome of primary endodontic treatment following use of different instrumentation techniques.
Materials and methods: Study subjects were recruited from the pool of patients referred for the non-surgical root canal treatment in the Department of Conservative Dentistry & Endodontics at PGIDS, Rohtak (Haryana).
The study population comprised of patients requiring primary root canal treatment following the diagnosis of pulpal necrosis with chronic apical periodontitis in mature mandibular first and second molars.
Subjects were allocated to one of the three study groups: manual instrumentation, ProTaper instrumentation and Hybrid instrumentation.
详细描述
AIMS AND OBJECTIVES
The present study has been designed with the following aims and objective:
- To evaluate the effect of manual / rotary/hybrid instrumentation techniques on success of primary non surgical root canal treatment in teeth with apical periodontitis.
- To assess the incidence of postoperative pain in teeth treated with and without rotary instrumentation.
- To compare manual, rotary and hybrid instrumentation techniques in terms of periapical healing in teeth with apical periodontitis.
METHODOLOGY
Prior to treatment a thorough clinical and radiological examination was carried out. A thorough history was taken from each patient. Prior informed consent was taken after explaining the procedure, risks and benefits.

结局指标
主要结局
Radiographic success
时间窗: till 12 month period
Periapical radiolucency was graded as Periapical Index (PAI) and scores less than 3 were grded as success
Clinical success
时间窗: 12 months
Absence of pain tenderness sinus or swelling was graded as clinical success
次要结局
- Pain intensity(every 24 hours for 7 days)
