Evaluation with structural equation modeling of variables affecting health-seeking behaviors during the COVID-19 pandemic in İstanbul, Türkiye.

Background/aim: The relation between the demographic characteristics of individuals and their health-seeking behaviors was presented and the effects of health cognitions, healthy lifestyle behaviors, and coronavirus fear levels on health-seeking behaviors during the COVID-19 pandemic were examined.

Materials And Methods: This descriptive survey study was conducted in the Tuzla District of İstanbul, Türkiye, between March and June 2021.

Results: From analysis of the 391 participants, 60.

Accuracy of Color Determination by Intraoral Scanners in Bleached and Unbleached Teeth: A Clinical Study.

Purpose: This clinical study aimed to evaluate the color measurement ability of intraoral scanners (Trios 3, (3Shape, Copenhagen, Denmark) and Cerec Omnicam, (Dentsply Sirona, Charlotte, NC, USA) in comparison to VITA Classical and VITA 3D-Master shades obtained by a spectrophotometer (Easyshade V, VITA, Zahnfabrik, Bad Säckingen, Germany).

Methods: Four hundred eighty teeth from thirty patients were included in the study. Fifteen patients had never undergone bleaching, and the other fifteen had undergone professional bleaching within the last 6 months.

Combined Minimally Invasive Esthetic Rehabilitation of Dental Fluorosis-5-year Follow-up: Case Report.

Dental fluorosis (DF) is a specific esthetic issue characterized by a persistent condition in which there is a disruption in enamel development, leading to the formation of hypomineralized enamel. The resulting unusual appearance varies in intensity, presenting as mildly white and opaque to dark brown, and significantly impacts individuals' esthetic features and self-confidence. The objective of this case report was to assess the efficacy of microabrasion, dental whitening, and resin infiltration in terms of resolving lesions, tracking the sensitivity of teeth, and evaluating patient satisfaction over a period of time.

The Effects of MMP3 (rs679620) and VDR (rs731236) Gene Polymorphisms on Dental Caries: A Pilot Study.

Objective:  Caries formation is a process affected by various factors. Studies have shown that genetic factors also play a role in caries formation. The aim of our study is to examine the effects of matrix metalloproteinase ( (rs679620) and vitamin D receptor () (rs731236) gene polymorphisms on caries formation.

In-vitro evaluation of wear characteristics, microhardness and color stability of dental restorative CAD/CAM materials.

The aim of this study was to demonstrate the vertical and volumetric wear characteristics of CAD/CAM materials. The microhardness and color stability were evaluated. A polymer infiltrated ceramic network CAD/CAM block, resin nanoceramic CAD/CAM blocks, a resin composite, and enamel tissue were investigated.

Effect of Polymerization on the Color of Resin Composites.

Objectives: The initial shade of a resin-based restorative material should be the same as that after polymerization. In this study, the color changes of translucent and opaque composites from nine different brands were assessed after polymerization using a spectrophotometer and cross-polarization (CP) photography.

Methods And Materials: Thirteen nano-hybrid (Essentia LE, GC Corp; Ceram.

Effect of Modeling Resins on Microhardness of Resin Composites.

Objectives:  This study was aimed to determine the effects of modeling resins on the surface microhardness of composites.

Materials And Methods:  Six resin-based composites (Charisma Smart, Estellite Asteria, CeramX-One SphereTEC, Admira Fusion, Filtek Ultimate, and Clearfil Majesty Es-2) and three wetting agents (Modeling Liquid, Composite Primer, and Modeling Resin) were investigated. In all, 240 specimens were prepared, and wetting agents were applied prior to light curing in the experimental groups.

Effect of sodium ascorbate and delayed treatment on the shear bond strength of composite resin to enamel following bleaching.

Background: The effect of bleaching on enamel surfaces, as well as exploring methods of preventing the weakening of bond strength of two different adhesives to bleached enamel surfaces.

Objective: This study compared the shear bond strength (SBS) of two different adhesives on bleached enamel immediately after bleaching, with a 1-week delay, and following application of an antioxidizing agent after bleaching. Materilas and Method: The enamel surfaces of 140 incisors were divided into 14 groups.

Thermal, spectral, and surface properties of LED light-polymerized bulk fill resin composites.

The aim of this study was to evaluate the thermal, spectral, and surface properties of four different bulk fill materials – SureFil SDR (SDR, Dentsplay DETREY), QuixFil (QF, Dentsplay DETREY), X-tra base (XB, Voco) X-tra fil (XF, Voco) – polymerized by light-emitting diode (LED). Resin matrix, filler type, size and amount, and photoinitiator types influence the degree of conversion. LED-cured bulk fill composites achieved sufficient polymerization.

IPS Empress onlays luted with two dual-cured resin cements for endodontically treated teeth: a 3-year clinical evaluation.

The aim of this study was to evaluate the performance of IPS Empress ceramic onlays luted with two dual-cured adhesive resin cements for endodontically treated teeth. Twenty molar teeth were restored with all-ceramic restorations luted randomly with Maxcem or Clearfil Esthetic Cement and DC Bond Kit luting systems (n = 10 each) in 20 patients. The restorations were assessed using modified US Public Health Service criteria at baseline, 6 months, and 1, 2, and 3 years.
