Comparative in-vitro microscopic evaluation of vertical marginal discrepancy, microhardness, and surface roughness of nickel-chromium in new and recast alloy.

Reusing of alloy has become a need of time due to the increasing demand, depletion of resources, and substantial increase in their price. The alloys used require a long-term stay in the oral cavity exposed to a wet environment, so they must have good wear resistance, biocompatibility, and mechanically good strength. In this study, the vertical marginal discrepancy, surface roughness, and microhardness of the new and recast nickel-chromium (base metal) alloys were evaluated.

Analysis of modified palatal surface for better speech in edentulous patients: A clinico-analytical study.

Background: Phonetics with mechanics and aesthetics are considered cardinal factors contributing to the success of complete dentures.

Objective: The aim of the current study was to evaluate the changes in speech in complete denture patients with and without palatal surface changes.

Methods: The data collected for the study involved completely edentulous Patients (n= 80).

The Association of Socioeconomic and Lifestyle Factors with the Oral Health Status in School-Age Children from Pakistan: A Cross-Sectional Study.

The data on how lifestyle factors of school-going children affect their oral health are not sufficient; therefore, there is a need to analyze the adverse effects of poor lifestyle habits and the role of mothers' education on oral health. The aim of this study was to analyze the association of socioeconomic and lifestyle factors with the oral health status of school-going children through a structured questionnaire and oral examination. Ninety-five (26.

Novel use of chloro-aluminum phthalocyanine assisted photodynamic therapy helps in periimplant healing among smoking patients.

Aims: To evaluate the clinical and biochemical peri‑implant parameters using chloro‑aluminum phthalocyanine-(CAP) mediated antimicrobial photodynamic therapy (PDT) as an adjunct to non-surgical mechanical debridement (NSD) in cigarette smokers (CS) and never-smokers (NS) with peri‑implantitis.

Materials And Methods: Thirty-two patients with peri‑implantitis [Group CS - 16 and Group NS - 16] were recruited for the trial. The study participants underwent two therapies: PDT + NSD and NSD alone.

The accuracy of gypsum casts obtained from the disinfected extended-pour alginate impressions through prolonged storage times.

Background: Manufacturers of the extended-pour alginates claimed their dimensional stability through prolonged storage. No data confirmed the ability of these materials to maintain their dimensions and the reproduced oral details following their chemical disinfection. Therefore, this study evaluated the dimensional stability and surface detail reproduction of gypsum casts obtained from disinfected extended-pour alginate impressions through different storage time intervals.

Predoctoral dental implant education techniques-students' perception and attitude.

Purpose: Dental implant (DI) therapy is in high demand and can only be rendered efficiently to graduating dentists by effective teaching methodologies. This study aimed to assess the perceptions and attitudes of dental graduates towards predoctoral DI education techniques and rehabilitation by DI.

Methods: A total of 26 well-structured questionnaires were distributed to 120 final-year students.
