The description of the Bednar's ulcer is uncommon in the current literature. It has been associated with the traumatic effect of the bottle's nipple and/or no orthodontic soothers while breastfeeding. We present a newborn of 20 days of life attended at the emergency room for irritability, with the only finding on physical examination of two oral ulcers. We describe the clinical presentation, evolution and treatment. The normality of the diagnostic test, clinical characteristics and evolution lead to the diagnosis of Bednar´s ulcer...

AIMS: The goal was to determine the influence of different geometric parameters of the tooth on the initial tooth mobility and the position of the center of resistance employing numerical models based on scaled X-ray images and plaster casts. METHODS: The dimensions of tooth 21 were measured in 21 patients, using radiographs and dental casts. Length and mesiodistal width of the tooth were obtained from the X-ray image and the orovestibular diameter from the plaster cast...

Orthodontic tooth movement results from the response of the periodontal tissue to orthodontic force, which leads to modeling and remodeling of the surrounding alveolar bone. The response is considered to occur through the activation of specific signaling pathways, many of which are known, all acting to ultimately result in tooth movement. Much is known about the actions of these two cells, and the signaling pathways that affect them, both in bone and orthodontic literature, however, to date, little work has been carried out to examine the effect of the insulin-like growth factor binding proteins (IGFBP) in orthodontics...

AIM: The aim of this in vitro study was to evaluate the influence of the Dental chair light on the bond strength of light cured composite resin. MATERIALS AND METHODS: Sixty therapeutically extracted human premolar teeth were randomly allocated to two groups of 30 specimens each. In both groups light cured composite resin (Transbond XT) and MBT premolar metal brackets (3M Unitek) was used to bond brackets. In group I and II light curing was done using Light-emitting diode light curing units without and with the dental chair light respectively...

Objectives: The aim of this study was to explore the effect of capsaicin on expression patterns of calcitonin gene-related peptide (CGRP) in the trigeminal ganglion (TG) and trigeminal subnucleus caudalis (Vc) following experimental tooth movement. Material and Methods: Male Sprague-Dawley rats were used in this study and divided into small-dose capsaicin+force group, large-dose capsaicin+force group, saline+force group, and no force group. Closed coil springs were used to mimic orthodontic forces in all groups except for the no force group, in which springs were inactivated...

Material and Methods: The sample comprised 730 longitudinal orthodontic records from children (448 females and 282 males) with an initial mean age of 8.3 years (SD=1.36). The dental anomaly group (DA) included 263 records of patients with at least one dental anomaly identified in the initial or middle mixed dentition. The non-dental anomaly group (NDA) was composed of 467 records of patients with no dental anomalies...

It was the aim of the present investigation to examine whether the stimulating effect of parathyroid hormone (PTH) on human periodontal ligament (hPDL) cell proliferation and differentiation would be enhanced by hPDL/T-cell interaction involving Wnt10b signaling as a mediating pathway. hPDL cells were cultured from healthy premolar tissues of three adolescent orthodontic patients and exposed to PTH(1-34) in monocultures or co-cultures with CD8(+) T cells. At harvest, proliferation, alkaline phosphatase-specific activity (ALP), and osteocalcin production were determined by immunofluorescence cytochemistry, real-time PCR, biochemical assay, and ELISA...

This case study reports the successful outcome of horizontal root fractures of two different patients, which took place in permanent incisors. Report 1 describes a case of a 29-year-old patient who suffered a mandibular trauma affecting mainly the lower central incisors, caused by a car accident. A panoramic radiograph was taken right after the accident and showed a horizontal root fracture in the middle third of tooth 42, which went untreated. Report 2 illustrates a case of a 17-year-old male patient who searched for orthodontic therapy and the periapical radiograph showed horizontal root fracture in tooth 11 caused by a previous trauma, which went untreated as well...

An intricate balance between the periodontal tissues and the forces of occlusion, tongue, and lips helps to maintain a tooth in its physiologic position within the dental arch. Disturbances in the equilibrium can cause a tooth to migrate pathologically, often requiring multidisciplinary treatment approaches. The present case demonstrates, for the first time, the use of autologous platelet-rich plasma to aid in tooth repositioning after pathologic tooth migration. A 25-year-old woman presented with extrusion and labial migration of the maxillary left central incisor, a diastema of 3 mm, and grade II mobility...

BACKGROUND: The initial placement of orthodontic elastomeric separators can be uncomfortable and painful. Therefore, it is important to relieve this disturbing sensation to create a discomfort or pain-free orthodontic visit. The purpose of this study was to investigate the effect of a lidocaine/prilocaine topical anesthetic on pain and discomfort associated with the placement of orthodontic elastomeric separators. METHODS: Fifty subjects aging between 20-35 years were included in this study...

PURPOSE: We evaluated the long term effectiveness of maxillomandibular advancement (MMA) for OSAS treatment patients. This retrospective study reviewed the patients treated by MMA for OSAS between 1995 and 2009. They were evaluated by complete polysomnography, cephalometry and quality of life questionnaire. The minimum follow up was 3 years. Success rate was defined by an IAH <10 with at least a 50% reduction. MATERIAL AND METHODS: 88 patients had MMA during this period...
