ABSTRACT Objective To address the following PICOS question: Can single‐shade resin composites achieve a color match comparable to multi‐shade in tooth restoration? Materials and Methods A comprehensive search was conducted across multiple electronic databases identify vitro clinical studies evaluating restoration, terms of CIELAB (Δ E ab ) and/or CIEDE2000 00 differences metrics, using composites. The risk bias assessed Quality Assessment Tool For In Vitro Studies (QUIN Tool), while revised Cochrane Collaboration's tool (RoB 2) employed for randomized controlled trials (RCTs). Meta‐analyses were performed RevMan compare Δ values between ( p < 0.05). Results After initial screening, 15 4 RCTs met inclusion criteria qualitative synthesis, with 8 selected quantitative analysis. majority classified as medium bias, ranked low bias. on revealed that exhibited statistically significant higher surrounding structure compared composites, both However, usually reported promising outcomes materials. Conclusions This systematic review concluded provide more accurate direct restoration than materials when evaluated by instrumental analysis laboratory settings.

Given the increasing prevalence of individuals using charcoal-based dentifrices over extended periods without professional oversight, concerns have emerged regarding their potential effects.

The adhesive-resin composite pair has been the cornerstone of direct restorations in dentistry for many years. Resin composites are traditionally classified three ways based on their inorganic structure, organic composition and viscosity. While these classifications have long associated with optical, mechanical, clinical properties resin composites, recent studies indicate that this classification is not always valid. In years, a significant expansion range families occurred, each varying degrees validation through vitro studies. As result, new distinct structures, viscosities, indications emerged. Despite progress, formal features all still lacking, leading to terminological inconsistencies research potential confusion among clinicians. This brief review, supported by an exhaustive search dental literature, proposes system key help clinicians researchers easily identify characteristics formulations. modular classification, encompassing eight main 14 characteristics, particularly suited future developments, as current trends aim simplify procedures integrating multiple formulations into single products.

This study aimed to enhance the performance of dental resin composites (DRCs) by increasing content inorganic fillers while addressing potential health risks associated with Bisphenol A (BPA). To achieve this, BPA-based monomer Bis-GMA was replaced BPA-free Bis-EFMA. The then explored impact varying filler contents on physiochemical properties Bis-EFMA-based bulk-fill (BF-DRCs). Four distinct BF-DRCs were formulated, each different ranging from 70 wt% 76 wt%. tested depth cure (DOC), double-bond conversion (DC), water sorption (WS), solubility (SL), and cytotoxicity system. It notably investigated effects mechanical through flexural strength (FS), modulus (FM), Vickers microhardness (VHN), wear resistance, as well polymerization shrinkage, including volumetric shrinkage (VS) stress (SS). assess commercial application BF-DRC, research used commercially available BF-DRC Filtek Bulk-Fill Posterior (FBF) a control. results indicated that higher did not affect DOC BF-DRCs.
