Patients with congenitally missing maxillary lateral incisors may seek treatment from an orthodontist for several reasons; unpleasant smile, dental arch disharmony, and midline deviations are among the most frequent complaints. Orthodontists and prosthodontists have raised important questions about the esthetics, occlusion, periodontal health, and(More)
OBJECTIVE To test the hypothesis that there is no difference in the cephalometric pattern between mouth breathing children with primary dentition and mixed dentition. METHODS Cephalometric measurements of 126 mouth breathing children (MB) were compared to 126 nasal breathing controls (NB). Both groups were divided into deciduous dentition (mean age 4(More)
OBJECTIVE To test the null hypothesis that enamel deproteinization with 10% papain gel does not increase the shear bond strength of orthodontic brackets bonded with resin-modified glass ionomer cement (RMGIC). MATERIALS AND METHODS One hundred and twenty bovine incisors were used and divided into eight groups: 1) Transbond XT according to the(More)
OBJECTIVE To investigate the effect of Lithothamnium sp (LTT) supplement, a calcium-rich alga widely used for mineral reposition, on strain-induced (orthodontic tooth movement [OTM]) and infection-induced bone resorption (periodontal disease [PD]) in mice. MATERIALS AND METHODS Mice were divided into two bone resorption models: one with an orthodontic(More)
INTRODUCTION The purpose of this study was to evaluate the skeletal and dental changes in the maxillae of patients with clefts treated with 3 expanders: hyrax, fan-type, and inverted mini-hyrax supported on the first premolars. METHODS Thirty patients with unilateral cleft lip and palate with transverse maxillary deficiency were divided into 3 groups,(More)
The objective of this study was to test the effects of enamel deproteinization on bracket bonding with conventional and resin-modified glass ionomer cement (RMGIC). One hundred premolars, extracted for orthodontic reasons, were divided into five groups (n = 20). Group 1 (control): enamel was etched with 35 per cent phosphoric acid, a thin layer of adhesive(More)
Introduction: The systematic search for increased efficiency in orthodontic treatment is shared by several areas of orthodontics. Performing alveolar corticotomies shortly before the application of orthodontic forces has been suggested as a method to enhance tooth movement and, consequently, orthodontic treatment as a whole. Objective: This article reviews(More)
This paper is the first to describe dental findings and orthodontic characteristics of a young adult patient with Lowe syndrome. This syndrome is a rare genetic disorder inherited by a sex-linked pattern, involving primarily the kidneys, eyes and nervous system, which also present oral manifestations. This paper also present the results of careful extra and(More)
OBJECTIVE To assess the color stability of five types of ceramic brackets after immersion in potentially staining solutions. METHODS Ninety brackets were divided into 5 groups (n = 18) according to brackets commercial brands and the solutions in which they were immersed (coffee, red wine, coke and artificial saliva). The brackets assessed were Transcend(More)
