Background: Oral health as an integral part of general health. Rural population neglect oral health as they lack awareness on oral diseases and also due to inadequate availability of dental services. There is a very high prevalence of chronic inflammatory periodontal disease in the rural Indian population, which is left untreated.

Stem Cells and Their Application in Dentistry: A Review.

The use of the term "stem cells" dates back to the 1800s; however, the application of the same is still not completely understood. Recent advances have indicated the harvesting of postnatal stem cells from sources such as the dental pulp and fat. The pluripotent nature of these cells allows for use in various aspects of treatment and patient care such as organ and tissue transplantation, bony defects repair, distraction osteogenesis, cell therapies, gene therapy, and toxicology testing of new drugs.

Efficacy of Denture Cleansers on Impact Strength of Heat polymerized Acrylic Resins.

Purpose: The study was aimed to compare and evaluate the changes in the impact strength of heat cure denture base resins when treated using denture cleansers.

Methodology: Study was conducted with sample size of 40 and dimesion 65 mm length, 10 mm width, and 3 mm thickness as per the ISO 1567. Distilled water has been used as control group, in which 10 samples were immersed of 40 samples.

An Evaluation of the Effect of Various Gloves on Polymerization Inhibition of Elastomeric Impression Materials: An Study.

Background: Latex protective barriers such as gloves and rubber dam material have been used widely in restorative procedures for crown and bridge. However, the chemical used during latex glove fabrication is thought to inhibit the polymerization of elastomeric impression materials used for impression making which has a detrimental effect on the dimensional accuracy and surface definition of resultant casts used for restorative procedures. The objectives of the study were to examine the surface of different elastomeric impressions on contact with various gloves.

Marginal Accuracy of Castings Fabricated with Ringless Casting Investment System and Metal Ring Casting Investment System: A Comparative Study.

Background: The thermal expansion of the investment can be restricted by the metal casting ring because the thermal expansion of the ring is less than that of the investment. The ringless casting procedure is in use in clinical dentistry, though there is little scientific data to support its use in fixed partial dentures. In this study, marginal discrepancy of castings produced with the ringless casting technique and the conventional technique using the metal rings were compared.

Posturedontics: How does dentistry fit you?

Dentists are at high risk for musculoskeletal disorders (MSD's) due to their work. MSD's is an umbrella term for number of injuries affecting different parts of the body, including joints, muscles, tendons, nerves that can arise from sudden exertion or making the same motions repeatedly. These injuries can develop over time and can lead to long-term disability.
