O assentamento passivo é um dos pré-requisitos mais importantes na reabilitação oral sobre implantes com carga imediata e na manutenção da osseointegração. Devido à importância da obtenção de passividade no sucesso de reabilitações protéticas sobre implantes, da não observância de consen...
O objetivo deste trabalho foi avaliar o desempenho de sistemas de diagnóstico óptico para detecção de lesões de cárie. No estudo in vitro, a viabilidade da transiluminação com laser infravermelho próximo (TI-NIR) para o diagnóstico de lesões iniciais de cárie foi avaliada. Dois examinadores a...
A necessidade de superar o desafio criado pelos biofilmes resistentes aos tratamentos antimicrobianos convencionais tem levado à busca por tratamentos alternativos, como terapia fotodinâmica antimicrobiana (aPDT). Este estudo avaliou in vitro a eficácia da aPDT na inativação de biofilmes de Staphylo...
In order for the pharmacological action of a topical dermal drug product to occur, the drug must first be released from the vehicle to be available to penetrate the skin layers and reach the site of action. Drug release is mainly dependent on the characteristics of the formulation. Currently, to register...
The antimicrobial activity of 13 total extracts was evaluated, 10 soft extracts (B) and 3 blended extracts (E) prepared from dry and fresh leaves of Petiveria alliacea L. Various solvents were used for their preparation: hydroalcoholic solution at 30%, 80% and isopropyl alcohol. The antimicrobial effect ...
Nanotechnology applies to diverse sectors of science. In cosmetic area, investments have strengthened the idea that nanoproducts provide innumerable benefits to consumers.

The purpose of this research study was to develop 5-fluorouracil compression coated tablets by using biodegradable polysaccharide polymer locust bean gum (LBG) and hydroxyl propyl methyl cellulose (HPMC) as coating materials. The fast disintegrating core tablets containing 50 mg of 5-fluorouracil were co...
Mycophenolate mofetil (MMF) and mycophenolate sodium (MPS) are an ester and a salt of mycophenolic acid. They have different kinetic in vivo characteristics due to differences in molecular structures, physicochemical properties and formulations administered. In this study, dissolution profiles of referen...
The aim of this study was to develop and validate a method for evaluating the release and skin permeation from transdermal nicotine patches using the vertical diffusion cell (VDC). The VDC is an experimental apparatus employed in research, development, and the pharmaceutical field because it can simulate...
The demand for fast dissolving tablets has been growing during the last decade, especially for elderly and children who have swallowing difficulties. In the present work, fast dissolving tablets of metoprolol tartrate, were prepared using sodium starch glycolate, sodium croscarmellose and crospovidone as...
