Influence of the Operator`s Experience, Working Time, and Working Position on the Quality of the Margin Width: In Vitro Study

Medicina, 2023
Background and Objectives: Appropriate tooth preparation is mandatory to obtain a perfect marginal fit of fixed restorations. The heavy chamfer is the most commonly used finish line, especially for minimally invasive tooth preparation.

A Blood‐Derived Double‐Network Hydrogel with Robust Wet Adhesion for Keratinized Mucosa Regeneration via Neutrophil Phenotype Reprogramming and Mechanophysical Niche Modulation

Advanced Science, EarlyView.
The iPRF‐MA/Alg‐NHS/Lut@EGCG (PGAE) double‐network hydrogel achieves durable wet adhesion in the oral environment. It simultaneously reprograms neutrophils from NETosis to phagocytosis for biofilm clearance, and activates the FAK‐RhoA‐YAP mechanotransduction pathway in gingival fibroblasts to drive extracellular matrix remodeling, thereby promoting ...

Beyond Potency: Emerging Determinants and Optimization Strategies Enhancing Therapeutic Efficacy of Adult Stem Cells

Advanced Science, EarlyView.
Adult stem cell therapy requires more than high in vitro potency. This review proposes a systems framework in which cell‐intrinsic programs, instructive microenvironmental cues, and pre‐/post‐delivery engineering are co‐designed under standardized translational rules.

Effectiveness of Using Analytical Grading Method for Crown Preparation Performed by Dental Students - An In-Vitro Study

Indian Journal of Dental Research
Introduction: Tooth preparations have traditionally been graded using a visual system that either subjectively assigns a single mark (global grading) or objectively divides the grade into several smaller categories.

Light‐Activated Ruthenium Nanoclusters Reprogram the Metabolic‐Quorum Sensing Axis for Precision Periodontitis Therapy

Advanced Science, EarlyView.
Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.

Tooth spray with active ingredients casein phosphopeptide – amorphous calcium phosphate (CPP – ACP) and ethanolic extract propolis (EEP) to inhibit tooth demineralization

Communications in Science and Technology, 2016
Dental caries is a disease caused by the microbial infection that produces localized damage to the tissue classification. The process begins by demineralization in hard tissue followed by damage to the organic material.

Over-reduction in tooth preparation

International Journal Of Community Medicine And Public Health, 2022
The treatment of carious lesions is the primary objective of tooth preparation and carious tissue excision. All carious lesions were previously treated invasively, or with cutting or drilling, and restoratively, or with the installation of restorative material following preparation and the elimination of carious lesion.
