- Brief Summary
This study will compare the effect of three different sealers on healing of teeth with apical periodontitis after primary root canal treatment.
- Detailed Description
Various sealers with different chemical composition and properties are available but it is yet not clear if one sealer is superior to other in terms of healing of apical periodontitis.
Three different groups of sealers will be used- a zinc oxide based sealer, an epoxy resin based sealer and a bioactive silicone based sealer. Mature mandibular permanent molar with the diagnosis of apical periodontitis (as confirmed clinically \& by periapical radiograph) will be chosen for the study. Primary non surgical root canal treatment will be performed. The sealer will be randomly selected just before obturation of root canals. The patient will be allotted to one of the three groups.
* Group I: Zinc oxide eugenol sealer group. The material will be mixed according to manufacturer instructions and applied to canals using a lentulospiral and the obturation will be performed.
* Group II: Epoxy resin based sealer group. The material will be mixed according to the manufacturer's instructions and obturation will be done.
* Group III: Bioactive silicone based sealer: The material will be used according to the manufacturer's instruction and obturation will be performed

- Primary Outcome Measures
Name Time Method Radiographic success 12 months Change in apical bone density will be measured by Periapical Index (PAI) score. PAI score equal to or less than 2 will be categorized as success.
Clinical success 12 months Absence of pain, sinus tract, swelling and mobility.
