Prosthetic abutment influences bone biomechanical behavior of immediately loaded implants

Braz. oral res. (Online); 30 (1), 2016
Abstract This study aimed to evaluate the influence of the type of prosthetic abutment associated to different implant connection on bone biomechanical behavior of immediately and delayed loaded implants. Computed tomography-based finite element models comprising a mandible with a single molar implant we...

Shaping ability of rotatory or reciprocating instruments in curved canals: a micro-computed tomographic study

Braz. oral res. (Online); 30 (1), 2016
Abstract This study aimed to compare apical transportation, centering ratio, and working time during root canal preparation with Wizard Navigator (WN), WaveOne (WO), or ProTaper Universal (PT) and to describe deformation and fracture of these instruments. Thirty-six mesiobuccal roots from maxillary molar...

Survival analysis of banding and bonding molar tubes in adult patients over a 12-month period: a split-mouth randomized clinical trial

Braz. oral res. (Online); 30 (1), 2016
Abstract: This split-mouth randomized clinical trial aimed to compare the survival rate of bonding and banding molar tubes in adult orthodontic patients. Eligibility criteria included adults (aged >18 years), no active caries, restorations, or fractures in the upper and lower molars. The main outcome ...

Validation of cone-beam computed tomography as a predictor of osteoporosis using the Klemetti classification

Braz. oral res. (Online); 30 (1), 2016
Abstract This study aimed at evaluating the validity of cone-beam computed tomography (CBCT) for assessing mandibular bone quality using the Klemetti classification. The morphology of the endosteal mandibular cortex of 30 (60 hemi-mandibles) postmenopausal women between the ages of 45 and 80 years was ev...

Effects of alveolar bone displacement with segmental osteotomy: micro-CT and histomorphometric analysis in rats

Braz. oral res. (Online); 30 (1), 2016
Abstract The purpose of this study was to evaluate the effects of segmental osteotomy on the blood vessels and osteoclasts in rats using micro-computed tomography (micro-CT) and histomorphometric analysis. After segmental osteotomy was performed around the maxillary first molars of 36 male Sprague-Dawley...

Tissue characterization following revascularization of immature dog teeth using different disinfection pastes

Braz. oral res. (Online); 30 (1), 2016
Abstract Revascularization of immature teeth with necrotic pulps traditionally involves the use of triple antibiotic paste, which may sometimes lead to undesirable complications. The objective of this study was to assess tissue repair in immature dog teeth with apical periodontitis subjected to revascula...

Chitosan-collagen biomembrane embedded with calcium-aluminate enhances dentinogenic potential of pulp cells

Braz. oral res. (Online); 30 (1), 2016
Abstract The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded w...

Antiseptics and microcosm biofilm formation on titanium surfaces

Braz. oral res. (Online); 30 (1), 2016
Abstract Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the main complication of oral...

Abstract Insomnia is becoming increasingly prevalent in the world general population. Therapies used by patients include over-the-counter therapies, herbal and dietary supplements, and pharmacological or nonpharmacological treatments. Among these, zolpidem is a pharmacological treatment popularly used fo...

Accuracy of clinical diagnosis for the identification of potentially malignant disorders and malignant lip lesions

Braz. oral res. (Online); 30 (1), 2016
Abstract: The aim of this study was to assess the accuracy of clinical diagnosis for lip lesions based on sensitivity and specificity. The retrospective analysis focused on the detection of lesions caused by potentially malignant disorders (PMDs) and malignant lesions (n = 1195). All cases were classifie...
