ABSTRACT
Treatment of mechanical exposure of the pulp during caries excavation presents a clinical challenge. In this case series of 15 patients, with a follow-up period of over a year, the outcome of direct pulp capping with Biodentine (septodont) after mechanical pulp exposure was assessed. Aim of Study: The aim of this study is to evaluate the outcome of direct pulp capping with Biodentine in deeply carious teeth when pulp was mechanically exposed during caries excavation and cavity preparation. Vital pulps exposed during caries excavation in molar teeth were treated with 3% sodium hypochlorite for 2 min. If adequate hemostasis was achieved, the pulp tissue was capped with Biodentine, which covered the entire pulpal floor. This was followed by the placement of a layer of resin-modified glass ionomer cement and a final layer of composite resin (Filtek Z350-3M) to complete the restoration. The patients were recalled periodically and evaluated for any evidence of pulpal/periapical pathology. Results: In the follow-up period that ranged from 12 to 24 months, all teeth were asymptomatic. Conclusion: Biodentine appears to be a suitable material for direct pulp capping under clinical conditions. However, long-term follow-up studies and controlled trials involving a large sample size are warranted.
ABSTRACT
Introduction: Periapical lesions generally develop as a sequel to pulpal infection. When there is a large periapical tendency visible on the radiograph, clinicians tend to have a surgical approach towards treatment. However a non- surgical approach with appropriate use of intracanal medicaments should be attempted to salvage teeth. This paper demonstrates healing of large periapical lesions in two cases by non – surgical Endodontic treatment Case Presentation: This report describes Endodontic treatment of a mandibular first molar and maxillary incisors. Calcium hydroxide in an aqueous vehicle was placed as intracanal medicament, the dressing changed every fifteen days for a period of three months. Continued follow ups demonstrated radiographic healing and the patients were asymptomatic. Conclusion: The case reports presented in this article showed healing of large periapical lesions following endodontic treatment. Isolation with rubber dam, thorough chemo mechanical debridement of the root canal space with use of calcium hydroxide as intracanal medicament is emphasized.
ABSTRACT
Aims: The purpose of this study was to compare the effect of various irrigation regiments on the push out bond strength of MTA Fillapex sealer to dentin. Study Design: Cross-sectional study. Place and Duration of Study: Department of Conservative dentistry and Endodontics, Hitkarni Dental College and Hospital (HDCH), between November 2014 and December 2014. Methodology: Thirty single-rooted premolar teeth were taken. Roots were divided into 3 groups according to the irrigation regiment used and instrumented using 5% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) irrigants as chemical auxiliary substances and 17% Ethylenediaminetetraacetic acid (EDTA) or 50% citric acid for smear layer removal. Finally, CHX solution was used as the final irrigant in one group. Root canals were filled with gutta-percha and MTA fillapex (Angelus, Londrina, PR, Brazil),a resin-based sealer. Bond strength was measured by the push-out test. Data were statistically analyzed by Kruskal-Wallis and Mann-Whitney U tests. Results: In the present study, specimens in G1 (NaOCl + EDTA + Distilled Water) & G2 (CHX + EDTA+ Distilled Water) group show lower push out bond strength values than G3 (NaOCl+ EDTA + Citric Acid +CHX) group. Conclusion: Thus, within the limitations of this study, we conclude that the different irrigation regiments did affect the push out bond strength of MTA Fillapex sealer to dentin. However the significant changes were not found between the various groups.
