Time Efficiency and Obturation Quality of Rotary Versus Manual in Primary Teeth

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the quality of obturation and the time efficiency of rotary versus manual instrumentation in roots of deciduous molars clinically where the: Primary objective Is to evaluate the time efficiency Secondary objective Is to evaluate the quality of obturation Clinical and radiographical follow up will be performed for 18 months to investigate the clinical and the radiographic success for the Conventional and Rotary groups.

Detailed Description
-----------------
The study will be conducted in two parts as follows: In-vitro part as a training part to practice, test the speed of the rotary system, followed by application clinically. Obturation will be done using two different filling techniques: Incremental filling Technique Disposable syringe Technique. Then the instrumentation time and the quality of obturation will be recorded. The study will be conducted by recruiting patients from the Outpatient clinic of The Pediatric Dentistry and Dental Public Health department, Faculty of Dentistry, Ain Shams University:

Eligibility Criteria
-----------------
Inclusion Criteria: - Children included in the study should conform to the following criteria: Patients between ages 4-7 years old with at least one mandibular vital or non-vital primary molar indicated for pulpectomy will be selected. Absence of periapical or interadicular radiolucencies, inflammatory root resorption, sinus tract or gingival abscess. No physiological root resorption.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Is to evaluate the time efficiency of the rotary mm files versus manual stainless steel k files in the pulpectomy of lower second primary molars affecting the positive behavior of the child | Time efficiency of instrumentation using rotary mm files specially designed for primary teeth versus manual stainless steel K-files in the pulpectomy of mandibular second primary molars, by clinical and radiographic evaluation for 18 months. | up to 18 months | 
| Is to evaluate and compare the quality of obturation using two different obturation techniques following instrumentation by rotary mm files and manual stainless steel k files instrumentation in another group | The quality of obturation using ZOE will be performed with either the incremental technique or the modified disposable syringe technique, following instrumentation by rotary and manual files, where the grading will be as : 1: overfilled, 2: underfilled 3: optimum filling. | up to 18 months |
