Assessing Mechanisms of Potential Local Adaptation Through a Seascape Genomic Approach in a Marine Gastropod, Littoraria flava.

Understanding the combined effects of environmental heterogeneity and evolutionary processes on marine populations is a primary goal of seascape genomic approaches. Here, we utilized genomic approaches to identify local adaptation signatures in Littoraria flava, a widely distributed marine gastropod in the tropical West Atlantic population. We also performed molecular evolution analyses to investigate potential selective signals across the genome.

Effect of the calcium silicate and sodium phosphate remineralizing products on bleached enamel.

Context And Aims: This study evaluated the effect of calcium silicate and sodium phosphate (CSSP) dentifrice and serum on the surface of enamel bleached with hydrogen peroxide (HO).

Materials And Methods: A total of 160 bovine enamel slabs were bleached with 35% HO and treated with sodium fluoride (NaF) dentifrice-GI, CSSP dentifrice-GII; CSSP dentifrice + CSSP serum-GIII, or NaF dentifrice + NaF gel-GIV. The dentifrices were applied using a brushing machine three times daily for 7 days.

Pomegranate extract on eroded dentin: antioxidant action, bond strength and morphology of the adhesive interface after aging.

Objectives: This study aimed to evaluate the effect of pomegranate solution () on eroded dentin through antioxidant action, shear bond strength (SBS) and interface morphology.

Materials And Methods: The 10% pomegranate peel extract was prepared by the lyophilization method. Punicalagin polyphenol was confirmed by high-performance liquid chromatography.

Physicochemical and mechanical properties of preheated composite resins for luting ceramic laminates.

This study analyzed and compared the physicochemical and mechanical properties of preheated resin composite with light-cured resin cement for luting indirect restorations. 210 specimens of resin cement/resin composite were prepared according to preheating treatment heated (Htd) or not (NHtd). Light-cured resin cement (Variolink Veneer, Ivoclar), and resin composite (Microhybrid-Z100, 3 M; Nanohybrid-Empress direct, Ivoclar; and Bulk fill-Filtek One, 3 M) were used (n = 10).

Clinical performance of sealants under different humidity control conditions: a split-mouth 1-year randomized trial.

Purpose: Sealants are an effective method of prevention and treatment for early caries lesions. This study analyzed the 1-year clinical performance of resin-based and ionomeric sealants applied to permanent teeth under different humidity conditions.

Methods: The investigation was a triple-blind randomized clinical trial (RCT) with a four arms split-mouth design, divided according to the sealant protocol: (1) Resin-based sealant applied with rubber dam isolation, (2) Resin-based sealant applied with cotton rolls isolation, (3) Ionomeric sealant applied with rubber dam isolation and (4) Ionomeric sealant applied with cotton rolls isolation.
