This in vitro study aimed to evaluate surface microhardness, roughness, color, gloss and topography of low-cost Brazilian resin composites, compared with an international one. All 120 samples (8mm ø x 2mm height) were prepared divided into 5 groups: Ultrafill (Biodinâmica), Llis (FGM), Fill Magic (Coltene), Applic (Makira), Filtek Z250XT (3M Oral Care). Surface microhardness (KHN) (n=10) was an...

Anaesthetic agents and doses used can significantly impact cerebrocortical responsiveness as assessed by electroencephalography (EEG). The objective of this study was to evaluate the effect three different halothane concentrations on EEG Rock Doves using measures frequency distribution burst suppression. Eight healthy (Columba livia) were anaesthetized with in oxygen, their tracheas intubated l...

background: a few studies have investigated the effect of the activation mode of adhesive systems on bond strength of fi ber posts to root canal dentin. this study investigated the push-out bond strengths of a glass fi ber post to different root canal regions with the use of two adhesives with light- and dual-cure polymerization modes. materials and methods: in this in vitro study, 40 maxillary...

background: the aim of this study was to determine phenolic acid composi­tion and anti-parasitic effects of peucedanum caucasicum, p. palimbioides, p. longibracteola­tum and p. chryseum on entamoeba histolytica . methods: methanol extracts of the plant species were prepared by soxhlet extrac­tion. phenolic acid compositions were determined by hplc. anti-prolifera­tive effect of extracts on trop...

We show that the one-way ANOVA and Tukey–Kramer (TK) tests agree on any sample with two groups. This result is based a simple identity connecting Fisher–Snedecor studentized probabilistic distributions proven without additional assumptions; in particular, standard assumptions (independence, normality, homoscedasticity (INAH)) are not needed. In contrast, it known for k>2 groups of observatio...

Objectives: To evaluate the microhardness and flexural strength of printed conventionally produced denture base acrylic resins. Methods: A total 32 parallelepiped specimens (64×10×3.3 mm) were manufactured using two light-cured resins suitable for 3D printing (V-Print Dentbase Denture 3D+) heat-cured conventional production (Probase Hot Villacryl Rapid) (n=8). After 24-h storage in water, Knoop...

PURPOSE The purpose of this study was to determine if vital tooth whitening affects oral health-related quality of life (OHRQOL) in adults age 50 years and older, and if tooth whitening causes increased participation in social activities. METHODS Using a 2 group, single blind, randomized, pre-test, multiple post-test design, 62 participants were enrolled. The experimental group used a whiten...

AIM To compare the attitudes and practices of a sample of veterinarians in New Zealand, Australia and the United Kingdom (UK) towards pre-pubertal gonadectomy of cats. METHODS Respondents' demographics were gathered using an electronic questionnaire distributed via professional veterinary associations in the target countries, as were minimum age at gonadectomy and typical age of puberty. Desi...
