Effects of Different Self-Adhesive Resin Cements and Curing Through Zirconia on Gingival Fibroblasts.

Introduction: Self-adhesive resin cements (SARCs) are widely used for fixed prostheses. These cements and their eluted products may affect periodontal tissues. This study aimed to investigate the response of human gingival fibroblasts (HGFs) to eluates from SARCs in vitro, simulating clinical conditions after prosthesis fixation, to gain insights into their potential effects on gingival health.

MMP inhibition, marginal integrity and cytotoxicity of zinc-releasing GIC.

Objectives: The degradation of the restorative-dentin interface due to endogenous dentin enzymes, such as matrix metalloproteinases (MMPs), is a significant issue that accelerates the deterioration of the dentin matrix and leads to the failure of restorative treatments. Caredyne Restore (CR), a novel glass ionomer cement (GIC) with zinc ions in its formulation, represents the latest effort to mitigate this issue. This investigation aimed to evaluate the MMPs inhibitory effect, marginal integrity, and cytotoxicity of CR compared to a conventional GIC, Fuji IX (FIX).

Clinical evaluation of direct composite versus zirconia resin-bonded fixed dental prostheses for a single missing anterior tooth: A short-term multicenter retrospective study.

Objectives: This study aimed to compare the outcome of a simplified direct composite resin-bonded fixed dental prostheses without reinforcing fibers (CR-RBFDP) and resin-bonded fixed dental prostheses using zirconia (Zr-RBFDP).

Methods: The clinical records of five private practice dental clinics and one university hospital were analyzed. Failure was defined as a RBFDP that was removed or remade for any reason.

Salivary proteomic signatures in severe dental fluorosis.

The relationship between dental fluorosis and alterations in the salivary proteome remains inadequately elucidated. This study aimed to investigate the salivary proteome and fluoride concentrations in urine and drinking water among Thai individuals afflicted with severe dental fluorosis. Thirty-seven Thai schoolchildren, aged 6-16, were stratified based on Thylstrup and Fejerskov fluorosis index scores: 10 with scores ranging from 5 to 9 (SF) and 27 with a score of 0 (NF).

Effect of Grinding and Polishing Protocols on Surface Roughness, Flexural Strength, and Phase Transformation of High-Translucent 5 mol% Yttria-Partially Stabilized Zirconia.

Objectives:  This study evaluated surface roughness, biaxial flexural strength, and phase transformation of 5Y-PSZ after grinding and polishing with different protocols.

Material And Methods:  Two commercial 5Y-PSZ, Lava Esthetic (L) and Cercon xt (C), were used and divided into 3 groups: LC and CC represented unpolished control groups; LE and CE were polished with protocol I (EVE DIASYNT® PLUS HP following with EVE DIACERA RA); and LJ and CJ were polished with protocol II (Superfine diamond bur following with Jota ZIR Gloss polishing kit). Surface roughness was evaluated after polishing step-by-step with a contact-type profilometer.
