Comparison of diagnostic effects of infrared imaging, visual inspection, and bitewing radiography in primary occlusal caries of permanent teeth.

Background: This study compared the diagnostic efficacy of VistaCam iX infrared camera, visual inspection, and bitewing-radiographs for the detection of primary occlusal caries of permanent teeth.

Materials And Methods: In this experimental study, 80 extracted human premolars were evaluated. The occlusal surfaces of these teeth were demineralized by immersion in a demineralizing agent.

Inhalational exposure to formaldehyde, carcinogenic, and non-carcinogenic risk assessment: A systematic review.

Formaldehyde is one of the most widely used substances in a variety of industries, although it was classified as a human carcinogen by the International Agency for Research on Cancer (IARC). The present systematic review was conducted to retrieve studies related to occupational exposure to formaldehyde until November 2, 2022. Aims of the study were to identify workplaces exposed to formaldehyde, to investigate the formaldehyde concentrations in various occupations and to evaluate carcinogenic and non-carcinogenic risks caused by respiratory exposure to this chemical among workers.

Different scoring methods of the VARK questionnaire to evaluate dentistry Students' learning styles.

Introduction: The way students process and organise information to facilitate learning is known as learning style. Knowing one's learning style can improve learning and help teachers choose their teaching methods more effectively. This study was conducted to investigate different scoring methods of the VARK questionnaire and compare different learning styles in different stages of dental school.

Characterization of the 3YSZ/CNT/HAP coating on the Ti6Al4V alloy by electrophoretic deposition.

In this article, the effects of the simultaneous addition of the 3 mol % yttria-stabilized zirconia (3YSZ) and carbon nanotubes (CNTs) reinforcements on different properties of the natural hydroxyapatite (HAP) coating were studied. The electrophoretic deposition (EPD) process was implemented to prepare thin coatings on the Ti6Al4V substrate. The coatings were then sintered at 1000 ° C under vacuum for 2 hr and the mechanical properties of them were studied by the nano-indentation method.

Synthesis and evaluation of the bioactivity of fluorapatite-45S5 bioactive glass nanocomposite.

This research study concerns the evaluations of nano-biocomposite ceramics' characteristics and biocompatibility. A nanocomposite with 45S5 bioactive glass base has been synthesized by sol-gel method. The synthesized nanocomposites were characterized with the help of different techniques, using field-emission scanning electron microscope, X-ray powder diffraction, energy-dispersive X-ray spectroscopy to evaluate the crystal structure, microstructure, and the morphology of the nanocomposite.
