To evaluate the influence of pretreatments on microtensile bond strength (μTBS) to eroded dentin when using a universal adhesive in self-etch mode. Forty-eight human molars were randomly assigned six groups (G1–G6, n = 8) and ground down until exposure. G2–G6 with citric acid (pH 2.6) for 10 × 2 min (within 12 h) 5 consecutive days. G1 G2 served as uneroded controls not pretreated. G3 G4 pretre...

: The purpose of giving space maintainer in primary dentition is to prevent the migration adjacent teeth, thus holding dental arch for succedaneous tooth erupt. Molar band fundamental component maintainer. retention surface important ensure fixed appliance therapy. Several methods have been described improve mechanical retentive surfaces bands including sandblasting, burs, etc. Sandblasting met...

Counterion distributions at charged flexible membranes are studied using analytical and simulation methods in both Poisson-Boltzmann and strong-coupling limits. The softer the membrane, the more smeared out the counterion-density profile becomes and counterions penetrate through the mean-membrane surface location, in agreement with anomalous scattering results. Repulsion between membrane charge...

Abstract Ferroelectric polymer films offer strong advantages like mechanical flexibility, biocompatibility, optical transparency, and low‐cost processing. However, their dielectric or piezoelectric performance is often inferior to that of oxide ferroelectric materials. Key the semicrystalline polymers enhancement electric dipolar order naturally lower than in crystalline ferroelectrics. Here, r...

To explore the possibility of providing additional reinforcement to bio-cemented sand through fiber inclusions, a series sand-fiber mixtures were prepared by mixing with three types fibers (polypropylene fiber, basalt and carbon fiber) at different contents (0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 0.8% volume sand). Each mixture was subjected two cycles controlled microbial-induced calcite precipitatio...
