RANDOMISED CLINICAL TRIAL TO COMPARE THE EFFICACY OF DENTAL WHITENING WITH 37.5% HYDROGEN PEROXIDE GEL AND 6% HYDROGEN PEROXIDE WHITENING STRIPS.: clinical study to compare the efficacy of dental whitening with 6% hydrogen peroxide whitening strips.

Objective: to evaluate the efficacy and chromatic stability after 4weeks, in all three thirds of the central incisor of two whitening treatments: in-office 37.5% hydrogen peroxide (HP) treatment alone, and 37.5% in-office HP followed by use of 6% HP whitening strips (WS).

Isolation of a Novel Caprine Strain (GC) in Canary Islands and Analysis of Parasitological, Clinical, and Pathological Findings on Experimentally Infected Goat Kids.

is considered among the most pathogenic species in goats. The aim of this study was to isolate an strain and to assess its infectivity, pathogenicity, and ability to develop a protective immune response. After previous collection of -positive faeces, purification of oocysts, and amplification in donor animals, an experimental infection was carried out.

VIRTUAL ENVIRONMENTS AND HUMAN ANATOMY LEARNING ACHIEVEMENTS IN UNIVERSITY STUDENTS.

Introduction: Virtual learning is characterized by the fact that the sender and the receiver are not present in the development of the learning sessions or in the same physical space; it can be synchronous or asynchronous. In certain subjects such as Human Anatomy, the teaching was face-to-face, which is why the question arose whether the virtual teaching of human anatomy was effective or ineffective.

Objective: To determine the relationship between virtual environments and learning achievements in the subject of human anatomy in students of a Peruvian university during the COVID-19 pandemic.
