A Comparative Analysis of Different Finishing and Polishing Devices on Nanofilled, Microfilled, and Hybrid Composite: A Scanning Electron Microscopy and Profilometric Study.

Unlabelled: The continuous development of esthetically acceptable adhesive restorative material has made a variety of tooth-colored materials available for clinical use. The advent of visible light polymerizing resin and the use of finer filler particles permit resin composites to be polished to higher degree. The effect of polishing systems on surface finish has been reported to be material-dependent, and the effectiveness of these systems was mostly product-dependent.

Anatomic and diagnostic challenges of C-shaped root canal system.

Successful root canal treatment depends on the thorough management of the canal anatomy. The use of periapical radiographs is essential to identify and monitor the canal's morphological variations. The C-shaped single canaled man-dibular 2nd molar probably requires a different regimen of treatment from the two rooted, three canaled version, as it is rare.

A survey report on effect of root canal fillings and coronal restorations on the periapical status of endodontically treated teeth in a selected group of population.

Aim: A cross-sectional radiographic orthopantomogram (OPG) survey was done to determine the prevalence of apical periodontitis (AP) in root canal-treated teeth in a selected population, and to evaluate the influence of the coronal restorations (CR) and root canal fillings on the periapical status.

Materials And Methods: A total of 250 OPGs were evaluated out of which root canal treatment (RCT) had been performed in 438 teeth which was taken as the sample size.

Statistical Analysis Used: Chi-square test, odds ratio and p-values were recorded.
