AI Article Synopsis
- The study evaluated the color stability of three types of resin cements (Choice 2, Panavia F2, and Panavia V5) after exposure to xenon radiation to assess any color changes over time.
- Fifteen specimens were tested, and their color changes (ΔE) were measured immediately after curing and again after 122 hours of radiation.
- Results showed that while all cements remained clinically acceptable in color change, Panavia F2 experienced the greatest change, whereas Panavia V5 had the least change after accelerated aging.
Article Abstract
Purpose: This study aimed to assess the color stability of resin cements subjected to xenon radiation and evaluate their color change (ΔE) during time.
Materials And Methods: In this experimental study, 15 specimens (8 mm in diameter and 2 mm in height) were made from a light-cured resin cement (Choice 2, Bisco, USA) and two dual-cured resin cements (Panavia F2 and V5, Kuraray Co, Ltd, Osaka, Japan). For assessment of color change, ΔE parameters were measured immediately (ΔE) and 24 h (ΔE) after polymerization using XRiteCi64 spectrophotometer. Next, they were subjected to xenon lamp radiation (122 h at 35C° and 22% humidity in off mode and 95% in light mode). Then, their color change was measured again (ΔE). The mean ΔE and standard deviation of all specimens were calculated, and data analysis was done using analysis of variance and Tukey's honestly significant difference.
Results: L* values had a tendency to decrease and Panavia F2 and Choice 2 had the highest change after accelerated aging. The comparison of Δa and Δb showed no significant difference between cements except Δa in Panavia F2. All the values were clinically acceptable (ΔE >3.3). The lowest Δ E1 was for Panavia V5 and the highest Δ E1 was measured for Panavia F2. After accelerated aging, there was no significant difference between Panavia V5 and choice 2 ( > 0/05).
Conclusions: Following polymerization and under xenon radiation, ΔE of all the specimens was clinically acceptable.

Dermatitis

Department of Dermatology, Park Nicollet Contact Dermatitis Clinic, Minneapolis, Minnesota, USA.
Colophony is a solid form of resin derived from coniferous trees that has both adhesive and water-resistant properties. For these reasons, this allergen is incorporated into many personal care products, medications, and occupational materials, and is thus commonly implicated in allergic contact dermatitis. Dedicated "dental" allergen series often include colophony, but dermatologists are likely not well-versed on its use in a dental setting.

Statement Of Problem: The optimal zirconia pretreatment, contingent upon the type of cement used, warrants further research.
Purpose: The purpose of this investigation was to evaluate the influence of various surface pretreatments on the bonding efficacy of cement to zirconia.
Material And Methods: A comprehensive search was conducted across the PubMed, Embase, Scopus, and Web of Science databases for in vitro studies related to bonding with zirconia up to April 2024, supplemented by a manual search.

The aim of this study was to assess the effect of a chlorhexidine digluconate solution (CHX) applied as an antiproteolytic agent for controlling erosive tooth wear or as part of the adhesive treatment on long-term bond strength to eroded dentin. Dentin specimens were abraded with a 600-grit silicon carbide (SiC) paper for 1 min (sound dentin - S), subsequently treated with 2% CHX for 1 min (with excess removed, followed by a 6-hour rest), and eroded by exposure to Coca-Cola for 5 min, three times a day, for 5 days (CHX-treated and eroded dentin - CHXE), or only eroded (eroded dentin - E). The specimens were acid-etched (15 s), rinsed (30 s), dried (15 s), and rehydrated with 1.

Background: This study aimed to assess the influence of different pretreatment protocols and antioxidants application on the shear bond strength (SBS) of universal adhesive to sound (SoD) and caries-induced dentin (CID).
Methods: One hundred and twenty posterior teeth had their occlusal enamel removed, then the specimens were divided into two main groups according to dentin substrates; SoD and CID, three subgroups according to pretreatments protocols control (no pretreatment), NaOCl-treated, and Er, Cr:YSGG-treated and two divisions according to antioxidant application (with and without sodium ascorbate (SA) application). All-Bond Universal (ABU) universal adhesives was applied in self-etch (SE) mode then resin composite discs were built.
