简要总结

The teeth were randomly allocated in two equal groups :

Control group (A):- included 20 mandibular primary molars in which pulpectomy were performed by hand instrumentation system using K- File from size 15 to size 35.

Experimental Group (B):- included 20 mandibular primary molars in which pulpectomy were performed by rotary system using Kedo-SG rotary file system according to manufacturer's instructions

Methods of Evaluation

Stage I :- During and after canal preparation:- The following parameters were evaluated for all cases in both groups:- A- The instrumentation and canal filling time were recorded for both groups using stopwatch. B- Radiographic assessment for filling were done immediately postoperative to record :-

  1. Distance between the apex to filling level of the mesial and distal roots .
  2. Obturation form

Stage II : Follow up :

The follow up were carried out by clinical and radiographic evaluation for all cases in both groups:-

The clinical evaluation were carried out at (0 base line = after 7 days ) then after 1 , 3 , 6 and 12 months .

Radiographic evaluation were performed immediately postoperative as (0 baseline ) after cementation of stainless steel crowns for assessment of filling quality. Radiographs will be used for comparison for consequent radiographs . Follow ups were performed after 6 and 12 months.

详细描述

The planned study is a randomized clinical controlled trial including apparently healthy children who were selected from the patients attending the Out- Patient Clinic , Pediatric Dentistry Department, Faculty of Dentistry, Suez Canal University. Informed written consent were obtained from parents or guardians of the children after full explanation of clinical procedures and detailed treatment plan.

The teeth were randomly allocated in two equal groups :

Control group (A):- included 20 mandibular primary molars in which pulpectomy were performed by hand instrumentation system using K- File from size 15 to size 35.

Experimental Group (B):- included 20 mandibular primary molars in which pulpectomy were performed by rotary system using Kedo-SG rotary file system according to manufacturer's instructions
