Características clínicas da associação entre o bruxismo do sono e o refluxo gastroesofágico merecem atenção profissional

Introduction: Bruxism has been defined as an oral parafunctional activity that includes clenching and/or grinding the teeth while asleep or awake. In addition to sleep bruxism (SB), various other orofacial movements sporadically occur during sleep. Occasional regurgitation and heartburn due to gastroesophageal reflux (GER) are frequent in the general population. GER refers to the presence of symptoms that are secondary to the reflux of gastric content through the esophagus with or without signs of esophageal mucosal lesions. Dentists are often the first health care professionals to diagnose GER through observation of its oral manifestation. Objective: The aim of the present case reports was to discuss the diagnosis and clinical procedures followed in two patients with SB and GER, thereby contributing to the dissemination of knowledge about these two entities. We therefore recommend dentists to be alert to identifying the first signs of GER that appear in the oral cavity. Conclusion: At this point, we highlight the importance of treating the patient as a whole, in an endeavor to identify other sources of the problems that could contribute as factors aggravating these conditions.

O Papel do cirurgião-dentista nas desordens alimentares: uma revisão de literatura

As desordens alimentares são um grupo de desordens psicopatológicas, nas quais o paciente relaciona os alimentos ingeridos com seu próprio corpo e, podem ameaçar a vida, como a anorexia e bulimia nervosa. Durante a progressão das desordens alimentares, pode ocorrer uma série de manifestações orais, as quais exercem um papel fundamental no diagnóstico, caracterização e prognóstico dessas desordens. O cirurgião dentista é, na maioria das vezes, o primeiro profissional da saúde a observar os sintomas clínicos de uma desordem alimentar. O objetivo deste trabalho foi realizar uma revisão de literatura sobre a etiologia, características, manifestações orais, e tratamento das lesões orais decorrentes das desordens alimentares. A pesquisa foi realizada nas bases de dados PubMed, SciELO, Bireme, durante o período de 1987 a 2013. Verifica-se assim que os primeiros sinais desenvolvidos em pacientes com desordens alimentares aparecem na cavidade oral, cabendo ao cirurgião dentista identificar esses sinais e relacioná-los às desordens.

Aplicação do enxerto conjuntivo subepitelial para recobrimento de recessões em dentes inferiores

Some regions of the oral cavity present anatomical conditions that seem to hinder the result of gingival recessions coverage. Thus, the aim of this case report was to present two surgeries for gingival recessions coverage in the mandibular teeth performed on the same patient with the follow-up of 24 months. Patient RP, 35 years old, male, Caucasian, nonsmoker, systemically healthy, sought care at the clinic of specialization course in Periodontics from the Araraquara Dental School (Foar-Unesp). His main complaint was the gingival recessions within the lower teeth 33, 34, 35, 43, 44 and 45. Besides the aesthetic nuisance, the patient reported occasional dentin sensitivity. For resolution of the case was referred to the technique of subepithelial connective tissue graft associated with a coronally advanced flap. After 2 years of surgery, it was observed an excellent root guards with significant aesthetic improvement of the case. It can be concluded that the subepithelial connective tissue graft technique was effective in covering of type class I gingival recessions of Miller, even in a region that provides a difficult procedure.

Tumores de cabeça e pescoço: epidemiologia, fatores de risco, diagnóstico e tratamento

Neoplasias of the head and neck correspond to the fifth most common cancer in the world, with high mortality and morbidity. The aim of this study was to show, through a literature review, a little about the epidemiology, risk factors, diagnosis and therapy of the most common malignant tumors of each anatomical region of the head and neck. The research of the articles was made in MEDLINE data base, with a total of 52 articles used. In this review, we analyze the main aspects related to the tumors of oral cavity, pharynx, larynx and salivary glands. Almost all cancers of the head and neck affecting the mucosa of the upper aerodigestive tract are derived from squamous cells. Therefore, the risk factors between the various types of tumors are similar, with alcohol and tobacco being the main ones. To be composed of several distinct structures, the head and neck tumors deserve a diagnostic and therapeutic approach individualized for each anatomical region. Controllingthe risk factors and doing the right approach, it is expected that the incidence of cancers of the head and neck decreases, thereby reducing mortality from malignant neoplasms worldwide

Halitose na geriatria: diagnóstico, causas e prevalência

Halitosis is the unpleasant odor of exhaust air through the mouth and lungs. There are over 50 causes, and approximately 90% of cases, is of oral origin. May have physiological origin (stress, breath of morning, fasting, and inappropriate diets), local reasons (bad oral hygiene, bacterial plaque retained on the tongue and/or tonsils, lower production of saliva, gum disease) or systemic reasons (diabetes, kidney or liver problems, constipation, etc.). In the Third Age, this problem tends to increase significantly. Thus, the aim of this study was to detect the presence of halitosis in the geriatric group attended in the dental clinic of UNIRP, identifying their incidence and principal causes. The sample consisted of 48 volunteer patients aged 60 years or older and included more than 90% of patients treated in this age group. It was performed a anamnesis and physical examination. The intra-oral halitosis was detected using a breath meter (halimeter). In the group studied, approximately 54.16% had halitosis, 84.61% of these were users of the prosthesis. The tongue coating was present in 80.76% of individuals with halitosis. After brushing the tongue, 88.46% of patients with halitosis have had the initial index oral malodor decreased. Based on the results of this study it was concluded that factors as dental prostheses and tongue coating are critical factors in causing halitosis.

Ectopic third molar as a cause of sinusitis

Ectopic third molar teeth are those that are impacted in unusual positions, or that have been displaced and are at a distance from their normal anatomic location. Ectopic eruption of a tooth within the oral cavity is common, but rare in other sites. Ectopic eruption can be associated with developmental disturbances, pathologic processes or iatrogenic activity. Male, 19- years old, with an upper left ectopic third molar located in the maxillary sinus-infraorbital region. The patient reported a bad taste and recurrent sinusitis that had been resistant to treatment. Surgical excision was carried out of the third molar tooth using the Caldwell-Luc approach.

Estudo da resistência à corrosão de ligas Ni-Cr-Mo-Ta E Ni-Cr-Mo-W em solução NaF 0,08 mol/L, pH 4,7 para aplicações odontológicas

A large number of metal alloys are used in Dentistry for the manufacture of fixed and removable dentures. In the oral cavity, these structures are exposed to a chemically aggressive medium, like saliva and mechanical efforts, like mastication. In addition, acidic solutions containing fluoride ions are also frequently used in dental treatments to prevent dental plates and decays development. In this context, it was considered important to investigate the influence that a fourth element could exert when added to the ternary alloy Ni-Cr-Mo, largely used in Brazil. Therefore, electrochemical tests were done to evaluate the resistance to corrosion of quaternary alloy 65Ni-25Cr-5Mo-5Ta and 65Ni-25Cr-5Mo-5W in NaF solution 0,08mol / L, pH = 4.7. For greater understanding the microstructure and morphology of alloys were studied, through metallographic analysis, using optics microscopy and electron microscopy scanning. For the electrochemical tests were applied techniques traditionally used in corrosion researches, such as: potential measures in open circuit (OCP) and cyclic polarization (CP). It was found that both quaternary alloys showed very similar results. Comparing these quaternary alloys with the ternary 65Ni-25Cr-10Mo, it was found that the quaternary alloys exhibit greater resistance to corrosion, in other words, less passivation current density than the ternary alloy, showing that it is advantageous to add a fourth element in the alloy
