Exploring the bio-mechanical behavior of PEEK and CFR-PEEK materials for dental implant applications using finite element analysis.

Purpose: This study explored the bio-mechanical properties of polyether ether ketone (PEEK) and carbon fiber reinforced-PEEK (CFR-PEEK) as potential alternatives to traditional dental implant materials, such as titanium (Ti) and zirconia (ZrO). Conventional implant materials often exhibit stress shielding leading to peri-implant bone loss and implant failure.

Study Selection: Finite element analysis using a three-dimensional computer-aided-design (3D CAD) model of the jawbone with various implant materials (titanium, zirconia, PEEK, and CFR-PEEK) incorporated was implemented to assess the effectiveness of PEEK and CFR-PEEK.

Comparative evaluation of enamel wear against monolithic zirconia and layered zirconia after polishing and glazing: An study.

Aim: The aim of this study was to compare the wear behavior of human tooth enamel opposing monolithic zirconia and layered zirconia after glazing and polishing by a two-body wear mechanism using a wear simulator.

Settings And Design: This In-vitro study was done in Department of Prosthodontics, Sri Sai College of Dental Research, Vikarabad.

Materials And Methods: Zirconia specimens were divided into four groups (n = 15), Group monolithic glazed zirconia (MG), Group monolithic polished zirconia (MP), Group zirconia layered with E.

Effectiveness of denture cleansers on flexible denture base resins in the removal of stains colored by food colorant solution: An study.

Aim: The aim of the study was to compare the efficiency of three denture cleansers (Valclean, Polident and Clinsodent) in removal of turmeric stains from flexible denture base resins.

Settings And Design: In vitro - comparative study.

Materials And Methods: A total of 45 specimens of flexible denture base resins were fabricated and subjected to baseline colour measurements using spectrophotometer.

Groove Pancreatitis: A Case Report and Review of a Hidden Type of Chronic Pancreatitis.

Groove pancreatitis is a chronic type of segmental or focal pancreatitis seen to affect the groove, which is the region between the head of the pancreas, the duodenum, and the common bile duct. Despite its incidence remaining unknown, it accounts for 2.7% to 24.

Insight from nanomaterials and nanotechnology towards COVID-19.

The pandemic coronavirus disease 2019 (COVID-19) becomes one of the most dreadful disease in the history of mankind in the entire world. The covid-19 outbreak started from Wuhan city of China and then rapidly transmitted throughout the world causing mass destruction and seldom. This sporadical disease has taken many lives due to sudden outbreak and no particular vaccines were available at the early wave.

Evaluation of flexural strength of Zirconia using three different connector designs: An study.

Aim: The aim of this study is to evaluate the flexural strength of zirconia using three different connector designs under vertical and oblique loads.

Setting And Design: Invitro - analytical study.

Materials And Methods: For simulating zirconia fixed partial prosthesis, a specimen with three octagonal cylinders connected with each other was designed.

Silver oxide nanoparticles embedded silk fibroin spuns: Microwave mediated preparation, characterization and their synergistic wound healing and anti-bacterial activity.

The synergistic wound healing and antibacterial activity of silver oxide nanoparticles embedded silk fibroin (AgO-SF) spuns is reported here. UV-Vis spectro photometric analysis of these spuns showed the surface plasmon resonance (SPR) confirming the formation of the silver oxide nanoparticles (AgO NPs) on the surface of the silk fibroin (SF). Scanning electron microscope (SEM) and Differential scanning calorimetry (DSC) also confirmed the presence of AgO NPs on surface of SF.

Green synthesis and characterization of silver nanoparticles using alcoholic flower extract of Nyctanthes arbortristis and in vitro investigation of their antibacterial and cytotoxic activities.

Here we report the synthesis of silver nanoparticles using ethanolic flower extract of Nyctanthes arbortristis, UVvisible spectra and TEM indicated the successful formation of silver nanoparticles. Crystalline nature of the silver nanoparticles was confirmed by X-ray diffraction. Fourier Transform Infra-Red Spectroscopy analysis established the capping of the synthesized silver nanoparticles with phytochemicals naturally occurring in the ethanolic flower extract of N.

Effect of various chemicals on the bond strength of acrylic tooth and denture base -An Invitro comparative study.

Background: Debonding of acrylic teeth from the denture base is a common problem. Certain clinical conditions like ridge prominence leads to excess trimming of acrylic teeth and base, resulting in a weak interface. The denture base polymer debonds adhesively in the region of the highly cross -linked matrix of the teeth.

Influence of quercetin on the pharmacokinetics of ranolazine in rats and in vitro models.

The aim of our study was to enhance the bioavailability of ranolazine by using herbal-bioenhancer quercetin in rats and to study the role of P-glycoprotein (P-gp) in vitro models. In single dose study (SDS), rats were divided into four groups, Group I was treated with 0.5% sodium carboxy methyl cellulose (SCMC), Group II was treated with ranolazine (14 mg/kg), Group III was treated with quercetin (20 mg/kg) and Group IV was treated with both ranolazine and quercetin.

Occlusion of primary dentition in preschool children of Chennai and Hyderabad: A comparative study.

Objective: To provide information on the state of occlusion and the spaces available after complete eruption of the primary dentition and to compare the characteristic features of the primary dentition in Chennai and Hyderabad, two of the metropolitan cities in South India.

Materials And Methods: Children in the age range between 3 and 5 years were selected from different schools of both Chennai and Hyderabad, with a complete set of primary dentition. Study casts were obtained and assessment of spacing in the primary dentition and the primary molar relationship were recorded in centric occlusion.

Trauma from occlusion - An orthodontist's perspective.

Orthodontic therapy has a big role in the treatment and prevention of malpositions. The signs and symptoms experienced by patients with occlusal trauma are mobility of teeth, temperomandibular joint pain, pain on mastication and periodontal disease. Early diagnosis, proper treatment plan and correction of malocclusion can lead to a successful outcome.
