Mechanical Vs Chemomechanical Method For Calcium Hydroxide Removal

Study Overview
=================
Brief Summary
-----------------
Type of study: Randomised Clinical trial To compare the effectiveness of Mechanical and Chemomechanical methods in the removal of Water-based Calcium hydroxide medicament from endodontic system. Participants allocated in group A and B should be appointed for Endodontic treatment of Single rooted teeth diagnosed with Necrotic Pulp and Chronic Apical Periodontitis. In group A, Calcium hydroxide medicament will be removed by using Mechanical method while in group B, Calcium hydroxide will be removed by using Chemomechanical method.

Detailed Description
-----------------
This study is aimed at comparing the effectiveness of Mechanical and Chemomechanical methods for removal of Intracanal medication. Water-based Calcium hydroxide is used as an Intracanal medicament in this study. Participants aged 18 years and above presenting to the Outpatient department of Operative dentistry and Endodontics, School of Dentistry, Shaheed Zulfiqar Ali Bhutto Medical University, Islamabad diagnosed with Necrotic Pulp with Chronic Apical Periodontitis will be randomly allocated in two groups A and B. On first visit, Root canal treatment will be initiated under rubber dam isolation. After locating canals, periapical radiograph for the working length will be taken. After working length has been confirmed, canal preparation will be done using Rotary file system. After canal has been prepared till working length, intracanal medicament is placed using Lentulospiral. Patient is recalled after 2 weeks. On next visit, Calcium hydroxide medicament will be removed by Mechanical method from group A. Mechanical method involves the use of Rotary file system for removal of medicament. In group B, Calcium hydroxide will be removed by using Chemomechanical method. Chemomechanical method involves the use of Sonic or Ultrasonic activation of irrigants for removal of medicament. After the removal of intracanal medicament, Periodical radiograph will be taken. Data will be taken on proforma and evaluation will be done for the effective removal of calcium hydroxide using a 4- point scoring system.
