Environmental concern and eco-entrepreneurial intention: the mediating effects of nature-based solutions and self-efficacy.

Environmental responsibility is crucial in both consumption and production processes. Increasing environmental concerns of societies require eco-innovative and nature-based solutions (NBS) for entrepreneurs. Young people's intentions as potential innovators and entrepreneurs on eco-entrepreneurship with mediating effects have not been investigated, which is a shortcoming in the literature.

Relationship Between Third Mandibular Molar Angulation and Distal Cervical Caries in the Second Molar.

Third lower molar partially erupted is commonly encountered in dental practice. This situation challenges clinicians with the dilemma whether to remove or to monitor it, because this molar can cause pathology of the adjacent second molar. The aim of this retrospective study is to evaluate the relationship between third mandibular molar and distal cervical caries in second molar.

Evaluation of five CAD/CAM materials by microstructural characterization and mechanical tests: a comparative in vitro study.

Background: Polymer infiltrated ceramics and nano-ceramic resins are the new restorative materials which have been developed in order to enhance the adverse properties of glass-matrix ceramics and resin composites. The aim of the present in vitro study was to evaluate the characteristics of various CAD/CAM materials through mechanical, microstructural, and SEM analysis.

Methods: Five test groups (n = 22) were formed by using the indicated CAD/CAM blocks: VITA Enamic (VITA Zahnfabrik), Lava Ultimate (3 M ESPE), IPS e.

Clinical evaluation of the stability of implants placed at different supracrestal levels.

Purpose: The aim of this study was to evaluate the stability during healing and before loading of implants placed at two different supracrestal levels according to their collar texture.

Materials And Methods: This retrospective study included patients who received posterior implants with the same macro design. Implants with a machined collar were placed 0.

Does the Laser-Microtextured Short Implant Collar Design Reduce Marginal Bone Loss in Comparison with a Machined Collar?

. To compare marginal bone loss between subgingivally placed short-collar implants with machined collars and those with machined and laser-microtextured collars. .

Curing efficiency of dual-cure resin cement under zirconia with two different light curing units.

Purpose: Adequate polymerization is a crucial factor in obtaining optimal physical properties and a satisfying clinical performance from composite resin materials. The aim of this study was to evaluate the polymerization efficiency of dual-cure resin cement cured with two different light curing units under zirconia structures having differing thicknesses.

Materials And Methods: 4 zirconia discs framework in 4 mm diameter and in 0.

Polymerization efficiency of two dual-cure cements through dental ceramics.

Purpose: The aim of this study was to evaluate the effect of thickness of zirconia on curing efficiency of resin cements.

Materials And Methods: Four discs with 4.0 mm in diameter were prepared from non-HIP translucent zirconia blocks using a CAD/CAM system and feldspathic ceramic was layered onto discs.

Clinical evaluation of marginal bone loss and stability in two types of submerged dental implants.

Purpose: The aim of this prospective clinical trial was to compare the three-dimensional marginal bone level, implant stability, and peri-implant health of two types of submerged dental implants that were restored with matching or platform-switched abutments.

Materials And Methods: Twenty-five subjects were recruited (test group: 43 implants with internal conical connection and back-tapered collar carrying a platform-switched abutment; control group: 50 implants carrying a matched-platform abutment). Implant uncovering and conventional loading were performed after 3 months of healing, and the total observation time was 15 months.

Cement selection for implant-supported crowns fabricated with different luting space settings.

Purpose: To measure and compare the retentive strength of cements specifically formulated for luting restorations onto implant abutments and to investigate the effect of varying cement gap on retention strength of implant-supported crowns.

Materials And Methods: Standard titanium abutments were scanned by means of a 3D digital laser scanner. One hundred and sixty standard metal copings were designed by a Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) system with two cement gap values (20 and 40 μm).
