Effects of different beverages on the color stability and fluorescence of resin composites: in situ study.

Objective: To evaluate the color change (ΔE) and fluorescence (FL) of resin composites after the consumption of beverages.

Materials And Methods: One hundred and sixty disc-shaped specimens (6 × 2 mm) of Filtek Z350 XT (FZX) and Forma (FOR) resin composites were randomized for use in devices by five volunteers who ingested 100 ml daily of red wine (RW), beer (BE), energy drink (ED) and water (WT) over 15 days. The data were collected from digital photographs and analyzed using the CIE-Lab and RGB scales to obtain ΔE and FL and statistics via two-way ANOVA (for ΔE) and ANOVA for repeated measures (for FL), α = 0.

Psychiatric medication use among pregnant and breastfeeding mothers who used cannabis for mental health concerns: A cross-sectional survey study.

Background: Use of cannabis during pregnancy and breastfeeding is increasing. Mental health concerns are reported as common reasons for maternal cannabis use, but little is known about the use of psychiatric medications in this population.

Objectives: This study aimed to describe psychiatric medication use among pregnant and breastfeeding mothers who used cannabis for mental health concerns.

Effect of hydroelectrolytic and energy beverages on the color stability and fluorescence of composite resins.

The objective of the present study was to assess the influence of energy and hydroelectrolytic beverages on the color stability and fluorescence of composite resins. Three composite resins (Amelogen, Filtek Z350 XT, and Filtek Bulk Fill) were analyzed at 4 different time periods: at baseline (T0) and after 1 (T1), 2 (T2), and 3 (T3) months of storage. Thirty specimens of each material were prepared and divided into subgroups (n = 10) based on the type of solution in which they were immersed for 1 hour a day at 37°C: distilled water (control), Red Bull, and Gatorade.

Effect of whitening dentifrices on the surface roughness of a nanohybrid composite resin.

Objectives: The present study verified the influence of whitening dentifrices on the surface roughness of a nanohybrid composite resin.

Materials And Methods: Thirty-two specimens were prepared with Filtek™ Z350 XT (3M/ESPE) and randomly divided into four groups (n = 08) that were subjected to brushing simulation equivalent to the period of 1 month. The groups assessed were a control group with distilled water (G1), Colgate Total 12 Professional Clean (G2), Sensodyne Extra Whitener Extra Fresh (G3), and Colgate Luminous White (G4).

A new methodology for fluorescence analysis of composite resins used in anterior direct restorations.

The aim of this study was to use a new methodology to evaluate the fluorescence of composite resins for direct restorations. Microhybrid (group 1, Amelogen; group 2, Opallis; group 3, Filtek Z250) and nanohybrid (group 4, Filtek Z350 XT; group 5, Brilliant NG; group 6, Evolu-X) composite resins were analyzed in this study. A prefabricated matrix was used to prepare 60 specimens of 7.
