Efficacy of Pediatric Rotary File System Versus Hand Instrumentation for Root Canal Preparation in Primary Teeth: An In Vivo and In Vitro Study
Abstract
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.
Conditions: Pulpitis.
Primary outcome: Spontaneous Pain; Sensitivity to percussion; Tooth mobility; Changes in mucobuccal folds (swelling, abscess or…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 40 participants or records.
