Antimicrobial study of cast post and its surface modification with nanoparticle.

A cast post is a one-piece unit that is custom fabricated for the tooth at the dental laboratory. Traditional extracts such as neem and green tea have good antimicrobial and antioxidant activity against pathogens. The empty canal space may provide a suitable environment for promoting bacterial growth.

Evaluation of Microbial Leakage at Implant Abutment Interfact for Different Implant Systems: An In Vitro Study.

Two-stage implant systems result in gaps and cavities between implant and abutment that can act as a trap for bacteria and thus possibly cause inflammatory reactions in the peri-implant soft tissues. These gaps between the components are inevitable, and their clinical significance has so far been mostly neglected by both manufacturers and clinicians. This study is thus intended to evaluate microbial leakage at implant abutment interface in different implant systems.

Polyether ether ketone - As an alternative biomaterial for Metal Richmond crown-3-dimensional finite element analysis.

Aim: This study was aimed to analyze the stress generation and distribution for "polyether ether ketone (PEEK)" and metal cobalt-chromium (Co-Cr) at different locations of the tooth using finite element analysis (FEA), when they are casted-off as "Richmond crowns."

Materials And Methods: The model of the tooth was designed using "computer-aided design/computer-aided manufacturing" followed by generating the "Mesh" of the tooth to analyze the stress caused by applying vertical and oblique loads of 100N and 40N, respectively, in cubical nodes for both PEEK and metal endodontic post-based Richmond crown. The "3-dimensional von Mises criteria" was used to compare stresses of both elements using FEA.

Three-dimensional-Printed Malo Bridge: Digital Fixed Prosthesis for the Partially Edentulous Maxilla.

Screw-retained implant restorations have an advantage of predictable retention, retrievability, and lack of potentially retained subgingival cement. However, a few disadvantages exist such as need for precise placement of the implant for optimal and esthetic location of the screw access hole and obtaining passive fit. Malo bridge with customization of abutment can establish a precise patient's gingival architecture.

Attitudes of students and teachers on cheating behaviors: descriptive cross-sectional study at six dental colleges in India.

Cheating behavior has been a serious problem in dental institutions across the globe. Attitudes of dental students have an impact on the quality of health care provided to their patients. This descriptive cross-sectional study had the following objectives: to assess and compare the attitudes of dental students and teachers about cheating behaviors, to assess students' opinions of various justifications for their cheating, and to assess teachers' attitudes towards various punishment options for cheating behaviors.
