Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

Interdisciplinary Medicine, EarlyView.
Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.

Evaluation of 6‐Month Knowledge Retention and Satisfaction After Pedagogical Escape Games in Dentistry

Journal of Dental Education, EarlyView.
ABSTRACT Purpose To evaluate 6‐month knowledge retention and long‐term satisfaction after two pedagogical escape games (PEGs) addressing foundational (3D printing) and clinical (pediatric dentistry) content in a dental curriculum. Methods In this monocentric serial cross‐sectional study, immediate post‑PEG knowledge was assessed in fifth‑year dental ...

Experimental studies on the pH levels that affect demineralization and remineralization of human tooth enamel.

Erbil Dental Journal, 2022
Background and Objective: It is thought that demineralization of enamel occurs below pH 5.5. We hypothesize that it also happens at higher levels. Furthermore, the effective pH levels for demineralization and remineralization differ from person to ...

Demineralized bone allograft fibers versus particulate in sinus augmentation: A double‐arm randomized controlled and histomorphometric study

Journal of Periodontology, EarlyView.
Abstract Background The primary aim of this study was to evaluate histologic wound healing of demineralized freeze‐dried bone allograft (DFDBA), in particulate (P) or fiber (F) form, in combination with deproteinized bovine bone mineral (DBBM) for maxillary sinus floor augmentation.

Protective Effects of Er:YAG Laser and PRG Pro‐Care Gel on Enamel Demineralization

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Bioactive surface pre‐reacted glass‐ionomer (S‐PRG) technology and high‐power laser irradiation have been investigated as promising preventive approaches. S‐PRG particles exhibit multifunctional bioactive glass properties, with the ability to release and recharge ions.

Remineralization and protection from demineralization: effects of a hydroxyapatite-containing, a fluoride-containing and a fluoride- and hydroxyapatite-free toothpaste on human enamel in vitro

Head & Face Medicine, 2022
Background The aim was to evaluate the remineralization potential as well as the extent of protection against renewed demineralization of enamel by hydroxyapatite-containing toothpaste (Karex) in comparison to fluoride-containing (Elmex) and fluoride ...

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

Macromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...

Demineralization Depth Using QLF and a Novel Image Processing Software

International Journal of Dentistry, 2010
Quantitative Light-Induced fluorescence (QLF) has been widely used to detect tooth demineralization indicated by fluorescence loss with respect to surrounding sound enamel. The correlation between fluorescence loss and demineralization depth is not fully
