Analyzing the Bioactivity of a Novel Bone Cement: An In Vitro Study.

Aim: To analyze the effect of bioactive bone cement (BBC) placed in a phosphate buffer saline solution in comparison to mineral trioxide aggregate (MTA).

Methodology: Ten samples each of BBC (group 1) and MTA (group 2) were prepared and stored in a phosphate buffer saline solution. After three days of storage, white precipitates were formed on the surface of the samples.

Influence of home bleaching regimen on microhardness and flexural strength of two contemporary composite resins - an in vitro evaluation.

Purpose: This study was to compare and evaluate the effect of home bleaching on the microhardness and flexural strength of microhybrid and nanohybrid composite resins.

Materials And Methods: The study samples were prepared using a custom-made silicon rubber mold. For microhardness evaluation, 40 disc-shaped specimens (4mm*2mm) were prepared and divided into 4 groups: GROUP A (n=10): microhybrid (GC Solaire X, GC Corporation) control group, GROUP B (n=10) nanohybrid (Tetric N Ceram, Ivoclar Vivadent) control group, GROUP C (n=10): microhybrid bleaching group, GROUP D (n=10) nanohybrid bleaching group.

Clinical Outcome of Nonsurgical Root Canal Treatment Using a Matched Single-Cone Obturation Technique with a Calcium Hydroxide-based Sealer: A Retrospective Analysis.

Introduction: The aim of this retrospective study was to estimate the outcome of nonsurgical root canal treatment using matched single-cones with a calcium hydroxide-based sealer and to identify the various prognostic factors influencing the outcome.

Methods: This was a retrospective study that enrolled 272 patients who underwent routine endodontic therapy and were obturated with matched single-cones and Sealapex as sealer. This study involved 223 patients with 261 teeth meeting the selection criteria and recalled between 24 and 84 months.

Evaluation of the correlation between dental caries and periodontitis - A clinico- immunological analysis.

Background: To study the correlation between dental caries and periodontitis.

Aim: The aim of the study was to evaluate the correlation between dental caries and periodontitis based on the clinical and immunological analysis. The null hypothesis was that there is no clinical and immunological correlation between dental caries and periodontitis.

Comparison of sealing ability of bioactive bone cement, mineral trioxide aggregate and Super EBA as furcation repair materials: A dye extraction study.

Context: Sealing ability of furcation repair material.

Aims: To evaluate the sealing ability of bioactive bone cement, mineral trioxide aggregate (MTA) and Super Ethoxybenzoic Acid (EBA) as furcation repair materials in mandibular molars using a dye extraction leakage model.

Settings And Design: In vitro, dye extraction study.
