The impact of postoperative intracoronal bleaching on the microtensile bond strength at the composite-dentin interface.

The study evaluated the effects of postoperative bleaching with HP and CP on microtensile bond strength (μTBS) and nanoleakage of composite restorations using total-/self-etch protocols. Sixty incisors with Black V cavities were restored using a multimode adhesive in total-/self-etch mode and resin composite. Samples were divided into five groups: control, CP×2, CP×5, HP×2, HP×5.

Home-use agents in the treatment of dentin hypersensitivity: clinical effectiveness evaluation with different measurement methods.

Objectives: This study aimed to evaluate the effectiveness of home-use desensitizing agents over an 8-week period by comparing them using different measurement methods.

Methods: A randomized, controlled clinical trial was conducted with 180 individuals aged between 18 and 70 who clinically diagnosed dentin hypersensitivity (DH) in two or more non-adjacent teeth. Subjects who met the inclusion criteria (n = 164) were randomly allocated into five test groups-using Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), Arginine, Novamin, Propolis, and Potassium nitrate-and a control group using standard fluoride toothpaste.

Cross-cultural adaptation of the Turkish version of the dentin hypersensitivity experience questionnaire short form (DHEQ-15).

Background: The short form of the Dentin Hypersensitivity Experience Questionnaire (DHEQ-15) is a valid and reliable tool for Oral Health-Related Quality of Life (OHRQoL) studies. The aim of this study was cross-culturally adapt and validate the English version of DHEQ-15 for the Turkish language.

Methods: The Turkish version of the DHEQ-15 was developed using the forward-backward translation method.

Evaluating the accuracy of Chat Generative Pre-trained Transformer version 4 (ChatGPT-4) responses to United States Food and Drug Administration (FDA) frequently asked questions about dental amalgam.

Background: The use of artificial intelligence in the field of health sciences is becoming widespread. It is known that patients benefit from artificial intelligence applications on various health issues, especially after the pandemic period. One of the most important issues in this regard is the accuracy of the information provided by artificial intelligence applications.

In-vivo evaluation of the effects of short-term dehydration and rehydration on the color differences of immature permanent incisor teeth.

Objective: It is aimed to evaluate the color changes of upper central incisor teeth with different root maturation levels after 15 min of dehydration and rehydration.

Materials And Methods: Using the Cvek classification, 60 participants were divided into five groups. A spectrophotometer, equipped with a specially designed jig, was utilized for color measurements.

Microhardness of glass carbomer and high-viscous glass Ionomer cement in different thickness and thermo-light curing durations after thermocycling aging.

Background: The objective of our study was to compare the upper and lower surface microhardness and surface changes of Glass Carbomer Cement (GCP) and EQUIA Forte (EF) in different thickness after thermo-light curing durations and aging.

Methods: A total of 504 samples (5 mm-diameter) were prepared by using GCP-252 (GCP Dental, and Vianen, Netherlands) and EF-252 (EQUIA Forte, GC, Tokyo, Japan). Three different thickness samples (2, 4, and 6 mm) were prepared with 84 samples in each subgroup.

Effects of Novel Finishing and Polishing Systems on Surface Roughness and Morphology of Nanocomposites.

Objectives: The purpose of this in vitro study was to evaluate the effects of different finishing/polishing techniques on the surface roughness of nanocomposites after thermocycling aging.

Materials And Methods: Five contemporary resin-based composites (Clearfil Majesty ES-2, Filtek Z550, Estelite∑Quick, Zenit, Filtek Z250) were tested. For each resin-based composite, 50 disc-shaped specimens were prepared and groups were divided into five subgroups according to the finishing/polishing methods (n = 10): control, finishing/polishing brush, finishing/polishing disc, and two different finishing/polishing wheels.
