Resumo Objetivo: Estudar, através do exame histopatológico, os depósitos de cálcio na córnea e suas diferentes formas de apresentação. Metodos: Estudo observacional, transversal, retrospectivo e descritivo de botões corneanos provenientes de ceratoplastia penetrante no período de 2006 a 2015. ...
SUMMARY: The quantitative morphology contributes to making the studies less subjective and reproducible. Quantitative results are analyzed with statistics and should be based on a well-defined sample. Quantitative variables can be 'continuous' or 'discrete.' In this text, the term 'morphometry' is used t...
ABSTRACT Purpose: To investigate the effects of pterygium on corneal endothelial cell density in patients with unilateral pterygium. Methods: We performed a cross-sectional analysis of data from patients with unilateral pterygium who were selected from September 1, 2015 to July 31, 2016 at Hospital de ...

ABSTRACT Purpose: Administration of eye drops containing antihistamines or sodium cromoglycate and its derivatives for the treatment of allergic keratoconjunctivitis is often insufficient and usually requires the addition of corticosteroids. However, the risk of complications, such as glaucoma and catar...

A fratura de instrumento durante a terapia endodôntica é uma complicação indesejável, que pode levar ao insucesso do tratamento. Quando isso acontece, exige-se novo planejamento do caso, visando uma mudança de conduta, com o intuito de remover ou ultrapassar o instrumento. É importante, nesse mome...
Collagen is the most abundant structural protein found in organs and is responsible for providing tissues with structure and function. In order to investigate in canine uteri the potential effect of medroxyprogesterone acetate (MPA) on the changes in collagen deposition were grouped as nulliparous (n=11)...
Sistemas de Secreção Tipo IV (T4SSs), normalmente compostos por 12 proteínas (VirB1-VirB11 e VirD4) são tipicamente associados às funções de conjugação bacteriana e transferência de fatores de patogenicidade para células hospedeiras. Mas também, muitas espécies da ordem Xanthomonadales possu...
ABSTRACT Objective: This study aimed to evaluate the effectiveness of two methods of visual magnification (operating microscope and light head magnifying glass) for removal of composite flash around orthodontic metal brackets. Material and Methods: Brackets were bonded in the center of the clinical c...
