BACKGROUND There are different mouthwashes containing chlorhexidine in different concentrations, as well as various excipients. Chlorhexidine induce stains or discoloration in teeth and mucous membranes. The aim of this work was to design a model to reproduce in vitro staining associated with the use of different mouthwashes containing chlorhexidine. MATERIAL AND METHODS We used as substrates...

INTRODUCTION White mineral trioxide aggregate (WMTA) has been reported to cause dental discoloration. A previous study on the color stability of 5 calcium silicate-based materials investigated the color stability of Biodentine (Septodont, Saint-Maur-des-Fossés, France) in different experimental environments; however, no data are available on the color stability of teeth restored with Biodentine...

Introduction: Tooth discoloration is a change in color that occurs on the enamel and dentin surfaces of tooth due to habit drinking tea. Some fruits are used as natural teeth whitening ingredients, such Manalagi Apple (Malus sylvestris), which contains malic acid. Method: This study was an experimental with pre-and post-test control group design involving 27 samples divided into three groups, C...

A two-year, 2-month old girl with Ehlers-Danlos syndrome Type VII is described. The patient presented with bleeding after tooth brushing, and exhibited microdontia and yellow discoloration of teeth. She had carious teeth, but did not exhibit periodontal disease, poor wound healing after extraction, radiographic evidences of pulp stones, or malformed roots. Microscopic examination of a decalcifi...

The impact of blood leakage due to microinjury to the oral cavity on the measurement of salivary hormones was examined. Saliva samples were collected before, immediately after, and then every 15 min for 1 h following vigorous tooth brushing. Blood in saliva was quantified by visual inspection of discoloration, Hemastix reagent strips to detect hemoglobin, and an immunoassay for transferrin. The...

The aim of this article is to report a rare anatomic case and the contribution of new technologies in best resolving it. Fusion is defined as the union of two separate tooth germs at any stage of tooth development. Planning treatment for this condition can be difficult and requires all diagnostic means available. A 45-year-old female patient presenting with a fused second and third molar underw...

UNLABELLED Older people who remain reasonably well may wish to maintain or enhance their dental and oral appearance, preferably at minimal biologic and financial costs. Bleaching and bonding represents a very good treatment option and a sensible strategy for this group. Bleaching addresses the discoloration, while direct composite bonding can improve the shape of worn, or otherwise unaesthetic,...
