Abstract

Aim: The aim of the study is to compare the apical microleakage of two Bioceramic sealers Ceraseal, MTA Fillapex and an Epoxy resin sealer (AH Plus) with two different obturation techniques single cone and thermoplastic obturation techniques using dye extraction method. Materials and Methods: 80 mandibular single rooted premolars were decoronated, & biomechanically prepared. The samples were randomly divided into eight groups with ten samples (n=10). Group (A1) contained roots samples obturated with Ceraseal sealer and a single cone Gutta percha. Group (A2) constituted samples obturated using Ceraseal sealer and thermoplastic obturation. Group (B1) samples were obturated with MTA Fillapex sealer with a single cone. Group (B2) contained roots which were obturated using MTA Fillapex sealer with a thermoplastic obturation. Group (C1) contained roots samples obturated using AH Plus sealer with a single cone. Group (C2) samples were obturated using AH Plus sealer with thermoplastic obturation. Group D and Group E served as positive and negative control. Apical leakage was assessed using dye extraction method. Results: Warm or cold obtuartion technique using sealers with different composition does not totally eliminate apical microleakage.   Keywords: AH plus, Ceraseal, Sealing ability, Single cone, MTA Fillapex, Thermoplastic obturation

Abstract

Effective and successful endodontic treatment requires dentists to have adequate information on the clinical variations in root canal anatomy. Maxillary premolars exhibit anatomical variations in the numbers of roots and canals, which pose a challenge during root canal therapy these variations must be considered for successful endodontic therapy. Herein, we illustrate the diagnosis and clinical management of previously endodontically treated three rooted maxillary premolars using Cone Beam Computed Tomography (CBCT).   Keywords: Anatomical variations, Endodontics, Three­Rooted Maxillary premolars, CBCT, Retreatment

Abstract

Aim & Objective: The objective of this in-vitro study is evaluation of remineralization potential of three remineralization agents- Tricalcium phosphate flouride(TCP-F), Calcium sucrose phosphate(CaSP), Casein phosphopeptide- amorphous calcium phosphate(CPP-ACP) in artificial enamel lesion using laser fluorescence based DIAGNOdent(KaVo). Materials and Methods: 30 single rooted premolars were selected. Samples were randomly divided into 3 groups with 10 samples each. Baseline values were recorded before any intervention. A 4mmx4mm window was prepared on the buccal surface which was then subjected to demineralization for 96 hr at 37°C. DIAGNOdent values were recorded after demineralization. Remineralization was done using Group I TCP-F, Group II CaSP, Group III CPP-ACP remineralizing agents. The samples were subjected to DIAGNOdent analysis after 72hrs, 7days, 14 days. Statistical analysis: The data was analyzed with analysis of variance (ANOVA) and Post Hoc test. Results: All three groups showed significant difference in DIAGNOdent values at baseline, post demineralization and post remineralization. TCP-F group showed maximum remineralization followed by CaSP and CPP-ACP groups. Conclusion: DIAGNOdent is a reliable non-invasive caries detecting device to measure early demineralization. TCP-F, CaSP, CPP-ACP are proven to possess remineralization properties.   Keywords: Calcium sucrose phosphate (TCP-F), Casein Phospho peptide- amorphous calcium phosphate (CPP-ACP), DIAGNOdent, Tricalcium phosphate fluoride (CaSP)
