Prevalence, satisfaction and preference of tooth shades and their correlation with age, gender and skin color : A cross sectional study.

Unlabelled: Shade selection is a crucial factor influencing patient satisfaction with dental prostheses and the overall success of treatment. Conventional visual methods of shade selection are inherently subjective, regardless of the availability of dental records or photographs. This study aims to assess the prevalence, satisfaction, and preference of tooth shades in a cross-section of the local Indian population and to evaluate their correlation with age, gender, and skin color in a diverse sample of 120 participants visiting the outpatient department of this Institution.

An In Vitro Comparison of the Influence of Air Abrasion, G-Multiprimer, and Salivary Contamination on the Shear Bond Strength and Surface Characteristics of Opaque Zirconia Ceramics.

Novel Techniques to Manage Temporomandibular Disorders - A Multidisciplinary Approach.

Temporomandibular joint is a compound, bilateral, ginglymoarthroidal joint articulating the condyle to temporal glenoid fossa. TMDs often project a constellation of signs and symptoms. Therefore, the treatment plan for TMD's should be more holistic.

Effectiveness of Two Wavelengths of Diode Laser and Amorphous Calcium Phosphate-Casein Phosphopeptide Mousse in the Treatment of Dentinal Hypersensitivity: A Randomized Clinical Study.

In office methods for immediate relief of dentinal hypersensitivity (DH) has long been an area of research. This study compared the efficacy of 660 nm diode laser, 980 nm diode laser, and amorphous calcium phosphate-casein phosphopeptide (ACP-CPP) agent in the treatment of DH. A total of 39 patients with minimum three hypersensitive teeth in at least one quadrant were selected and randomly divided into three groups; Group A, B, and C patients were treated by 660 nm diode laser, 980 nm diode laser, and ACP-CPP agent, respectively.

Osseointegrative and antimicrobial properties of graphene oxide nano coated dental implants: A systematic review.

Introduction: Osseointegration stands as a pivotal concept within the realm of dental implants, signifying the intricate process through which a dental implant integrates with the adjoining bone tissue. Graphene oxide (GO) has been shown to promote osseointegration, the process by which the implant fuses with the surrounding bone. The objective of this study was to assess the osseointegrative and antimicrobial properties of GO nano coated dental implants.

Cytotoxicity of dental cement on soft tissue associated with dental implants at different time intervals.

Background: To investigate and compare the effect of four commercially used dental cement at 24 hours, 48 hours,72 hours (h) and 6 days on the cellular response of human gingival fibroblast (HGF).

Methods: 3 cement pellet samples were made for each 4-test cement (n=12). The cement used for this study were zinc phosphate (ZP), zinc oxide non-eugenol (ZOE), RelyX U200 (RU200), and glass ionomer cement (GIC).

A Nonlinear Three-Dimensional Finite Element Analysis of Stress Distribution and Microstrain Evaluation in Short Dental Implants with Three Different Implant-Abutment Connections in Single and Splinted Conditions in the Posterior Mandible.

Background: Stress distribution plays a vital role in the longevity and success of implant-supported prosthesis. This study evaluated the von Mises stress and microstrain in the peri-implant bone and the implant-abutment junction of short dental implants with three different implant-abutment connections in splinted and unsplinted conditions using finite element analysis (FEA).

Materials And Methods: In this experimental study, nine transversely isotropic finite element models were developed, and randomly divided into three equal groups (n = 3): control, (Group AC) single-standard 4.

Cancer vaccines: An unkept promise?

Two decades ago, cancer vaccines were hailed as a prominent breakthrough for the treatment of cancer. However, the vaccines failed to show any improvement in median survival time in various clinical trials, even though they stimulated the immune response and showed exceptional safety profiles. The resistance of cancer cells to the immune response was revealed as a significant hurdle.
