Abstract

Aim: To seal with Mineral trioxide aggragate(MTA) and make a sizeable communication between the root canal system and the periradicular tissue and provide a barrier because of lack of apical constriction.Summary: A 9 year old girl who had met with trauma about six years ago, before she visited department of Paediatric Dentistry , Update Dental College,Dhaka,Bangladesh for the treatment of mandibular right lateral incisor. The case was diagnosed as necrosis of pulp with open apex. After proper isolation access opening and biomechanical preparation was performed with 1mm short of the radiographic apex and calcium hydroxideused as intra canal medicament. After 15 days MTA was placed in the canal till a barrier of 4mm was achieved. Later obturation was done using lateral condensation technique.Size of the periapical lesion was almost decreased after one year of follow up. Followup was done after 1 month, 6 months and 1 year later.Update Dent. Coll. j: 2015; 5 (1): 21-25

Highlights

The primary objective in endodontic therapy is the complete obturation of the root canal space to prevent re-infection

Calcium hydroxide has been extensively used to accomplish apical closure due to its ability to induce hard tissue formation, but it is more time consuming,which may between 3 and 21 months[17,18,25,26].Mineral Trioxide Aggregate (MTA) was used in immature premolars of dogs and was concluded that it induced apical plug more often with less inflammation.[19]

Summary

Introduction

The primary objective in endodontic therapy is the complete obturation of the root canal space to prevent re-infection. The aim is to seal a sizeable communication between the root canal system and the periradicular tissue and provide a barrier against which obturation material can be compacted.Because of the lack of an apical constriction, an alternative to standard root canal treatment, apexification or root end closure has been advocated.1,2Three. 1) Placement of a large gutta-percha filling or customized gutta-percha cone with sealer at the apex. These techniques did not gain popularity since there was no physical apical barrier to facilitate obturation. Two other techniques were reported which aimed to provide an apical barrier.[3]
