A Comparative Evaluation Of the effect ofvarious root canal sealers viz Bioceramic sealer ,Calcium hydroxide based sealer andResin based sealer on healing rate and post obturation pain after single visit endodontictreatment in asymptomatic infected root canal-A randomized Clinical Study.

AIM of study is to

1. To evaluate healing rate and post obturation pain in single visit root canal treatment using Bioceramic sealer (Bioroot RCS Septodont) as a root canal sealer.

2. To evaluate healing rate and post obturation pain in single visit root canal treatment using Calcium hydroxide based sealer (Sealapex Kerr Sybronendo) as a root canal sealer

3. To evaluate healing rate and post obturation pain in single visit root canal treatment using Resin based sealer (AH plus Dentsply DeTrey) as a root canal sealer.

4. To compare healing rate and post obturation pain in single visit root canal treatment with Bioceramic sealer (Bioroot RCS), Calcium hydroxide based sealer (sealapex) and Resin based sealer (AH plus) as a root canal sealer.

Scope:

In endodontic practice, the success of root canal therapy mainly depend on achieving a compact fluid tight seal of the apical end of the root canal, so as to prevent the ingress and accumulation of irritants causing biological breakdown of attachment apparatus leading to failure. Root canal sealers along with solid core material play a major role in achieving the fluid tight seal. Several types of root canal sealers are used in endodontic practice with each one having own merits and demerits. Sealers are basically selected based on their sealing ability, adhesive properties, biocompatibility & antimicrobial efficacy. Therefore ,with advent of new techniques and knowledge it becomes imperative that the use of advanced materials be used to increase the success rate of root canal treatment in single visit whenever possible. This study might help us to devise an advanced treatment modality directed at enhancing the success rate of root canal treatment and increasing tooth longevity.

Method:1

The case will be allocated into three different groups of 20 in each based on sealer used. Initially access cavity will be made under rubber dam isolation using a high speed air motor with water coolant. After shaping and cleaning of canal using 5.25% sodium hypochlorite, 17% EDTA and 2% chlorhexidine as root canal irrigants, each group will be sonic activated and then the canal will be obturated with gutta-percha cones using sealer: in Group 1 bioroot RCS used as a sealer ,in group 2 sealapex used as a sealer and in group 3 AH plus used as sealer by Cold lateral condensation technique followed by GIC restoration . Teeth will then be reviewed clinically and radiographically at 1months,3 months,6 months and 12 months. An intraoral radiograph will be taken as baseline record.
