Detecção de microrganismos de infecções bucais: perspectivas e cuidados a serem seguidos

The diagnosis of head and neck infections constitutes relevant step in their treatment. However, in spite of the fact that most of diseases in head and neck region are infectious in nature, several reasons collaborated for dentists do not ask laboratory tests in order to help clinical diagnosis. By mean of this review literature, based on research articles about the newest and most reliable methods of diagnosis for clinical laboratories, the authors discuss the advantages and disadvantages of each selected method and the relevant aspects in transportation of the specimens to the laboratory. Saliva, biofilm, pus, and blood are the most frequent specimens for microbial diagnosis, being that the most used methods are culture and those based on detection of deoxyribonucleic acid by polymerase chain reaction method. Whereas, the culture depends on cellular viability, and has reduced sensitivity, as well as needs favorable conditions in the sample collection and transportation, PCR shows high sensitivity and specificity, but it does not allow the determination of antibiogram, what reduces its usefulness. In addition, few laboratories possess conditions to perform cultivation of obligate anaerobes or have experience in the molecular detection of these microorganisms.

Doença de Lyme na região de cabeça e pescoço: implicações para a odontologia

Lyme disease (LD) is a systemic inflammatory changes resulting from the direct action of the spirochete Borrelia burgdorferi on the host or indirect damage produced by immune response to this microorganism. This pathogen is transmitted by inoculation in the bloodstream by the tick genus Ixodes and is most commonly found in North America, Europe and Asia. In these regions, the dental community is aware about its commonest clinical symptoms, collaborating with the establishment of a diagnosis. However, in Brazil, the frequent facial or peripheral neurological manifestations, among them the Bell's palsy, ocular disorders, disorders in the temporomandibular joint, as well as paresthesia of upper and lower alveolar nerves are observed. In our country, the diagnosis of Lyme disease is primarily based on clinical symptomatology, but most of cases remain without diagnosis and treatment. Then, the detection of the early manifestations of Lyme disease by health professionals is essential for the proper antibiotic treatment, preventing the progression of the disease, and allowing the establishment of favorable prognostic.

Halitose bucal: importância da saburra lingual e periodontite na sua etiologia

In general the human breath doesn't have smell or it is so only lightly perceptible to the surrounding ones, varying of pleasant the unpleasant, being taken in consideration the sensibility of the person. Halitosis or bad breath doesn't truly represent a disease, being present in a considerable portion of the population. Ethiologically exist several involved factors, could make an appointment breathing, gastric intestinal, organic and psychic disturbances and mainly oral factors, being the microbial colonization of the tongue the most common, beside the pathological situations involving periodontitis, as necrotizing ulcerative gengivitis. For representing a true obstacle biopsicossocial, the halitosis it influences directally in the family life, work, the patients' atmosphere social, being its diagnosis specific, demanding in certain occasions treatment multidisciplinar. In that sense, the present study if report to a literary revision of the theme, approaching the main aspects of the development of the halitosis, as well as its biological origin and its clinical implications.

Atividade inibitória de extratos de plantas da savana brasileira sobre microrganismos superinfectantes e oportunistas

A utilização de compostos naturais na medicina de populações tradicionais é uma realidade em todo o mundo e o cerrado brasileiro apresenta grande diversidade de vegetais com uso potencial no tratamento de infecções por microrganismos oportunistas. Esse estudo avaliou a atividade antimicrobiana dos extratos vegetais do cerrado brasileiro sobre microrganismos oportunistas e superinfectantes. Nos testes foram preparados extratos hidroalcoólicos e aquosos de 22 espécies de plantas utilizadas nas regiões Norte, Nordeste e Centro-Oeste como parte da medicina popular. Esses extratos foram testados sobre Enterococcus faecalis ATCC 19433 e Pseudomonas aeruginosa ATCC 10145 e dez isolados clínicos de cada uma dessas espécies microbianas. Inicialmente foi realizada uma triagem para se determinar a atividade antimicrobiana dos extratos. Em seguida, foram realizados testes para avaliar a maior diluição inibitória dos extratos por meio do método de diluição em caldo e testes de atividade inibitória em biofilme. Os resultados demonstraram que embora aproximadamente 20% de todos os extratos mostraram atividade inibitória sobre algum dos microrganismos alvo, os mais ativos foram os extratos aquosos e hidroalcoólicos de araçá e aroeira, se mostrando ativos frente a todos os microrganismos.

Chronic osteomyelitis of the maxilla and mandible: microbiological and clinical aspects

Osteomyelitis of the mandible and maxilla are common in developing countries and their treatment may be long-standing and difficult. Thus, the aim of this study was to discuss the main biological aspects of the chronic osteomyelitis of the jaws of especial interest for dental team. These infections are associated with a complex microbiota composed mainly by anaerobic bacteria, sometimes associated with microorganisms originated from the skin and digestive tract. These data suggest that chronic osteomyelitis of the mandible and maxilla should be treated as anaerobic infections in most cases. In addition, local surgical treatments are relevant in the therapy outcome, associated to the use of antimicrobial agents, and the failure to accomplish them is a major cause of treatment failure.

Protocolos de saúde geral e bucal de enfermagem em radioterapia de câncer de cabeça e pescoço: uma revisão comentada

O câncer é um problema de saúde pública mundial, com destaque para a incidência do câncer de cabeça e pescoço, em função da biologia das lesões, custo do tratamento, acompanhamento e ônus social. Seus tratamentos mais utilizados como a cirurgia e radioterapia, apresentam sérios efeitos colaterais de curto e longo prazo, cujo é são complexo. As principais orientações e cuidados no tratamento do câncer de cabeça e pescoço foram obtidos através de revisão de literatura sistemática em bases de dados públicas. O objetivo desta revisão de literatura foi mostrar os principais cuidados na prevenção e tratamento das sequelas da radioterapia desse tipo de câncer. Nesse particular, observa-se a necessidade de um protocolo de enfermagem-odontologia, visto a complexidade e a falta de direcionamento das normas do Sistema Único de Saúde, além da responsabilidade dos cuidados desses pacientes, que ficam a cargo da equipe de saúde, atendendo as suas reais necessidades, tanto pessoais, psicológicas e fisiológicas.

Severidade da mucosite bucal em pacientes com câncer de cabeça e pescoço submetidos à raditoerapia

Radioterapia é uma das modalidades terapêuticas mais utilizadas no tratamento de neoplasias de cabeça e pescoço. Contudo apresenta severos efeitos colaterais, dentre os quais a mucosite é uma das mais prevalentes e sérias, ocasionando áreas ulceradas com extremo desconforto para alimentação e possibilidades de infecções secundárias, muitas delas por microrganismos oportunistas. Esse estudo objetivou investigar a ocorrência e grau de severidade da mucosite oral em pacientes com lesões malignas de cabeça e pescoço submetidos à radioterapia, bem como relacionar com a interrupção do tratamento. 50 pacientes foram avaliados clinicamente e por meio de questionário, durante e após o tratamento, no Centro de Radioterapia de Megavoltagem em São José do Rio Preto-SP utilizando-se os critérios de mucosite da OMS. Pode-se verificar que a maioria dos pacientes apresentou algum grau de mucosite durante o tratamento e persiste em alguns pacientes mesmo após a interrupção da radioterapia. A má higiene bucal e tratamentos odontológicos prévios são fatores associados aos graus mais severos das lesões.

Condutas terapêuticas para caninos inclusos

Normally, the last teeth to erupt are the ones which remain impacted or semi-impacted, and that is the case of the canines. This study aimed to report a few options of treatment, aiming at esthetic and functional maintenance of the affected area before a impacted canine, discussing its indications, contraindications, advantages and disadvantages. This study also aims to emphasize the accessibility the patient would have in case his/her option were one of the approached ways of treatment. In order to identify the studies included or analyzed in this review, a detailed search strategy was performed for the database used: Pubmed, Bireme, Scielo, Cochrane, and Dentistry Oral Science up to 2011. We used non-erupted teeth, canine, and therapeutics as descriptors. The criteria of inclusion were clinical and review articles that approached the theme. Through this review, it was found that the surgeon dentist’s lack of technical and scientific knowledge and the financial impossibility of most population are some hindrances for the establishment of the right planning for the impacted canine.

Lichenoid reaction: case report

Lichenoid lesions are mucocutaneous disease of chronic inflammatory origin. Can produce side effects to drugs, dental materials, affecting 0.5 to 1% of the world population mainly in women in the fourth decade of life. The history and meticulous clinical servation may clarify the reactive nature, but the clinical diagnosis will only be conclusive when associated with tests such as histopathology. Therefore the objective of the study is to report a case of a woman of 55 years old, complaining of "white spots sore". Reported being allergic to metals, chocolate, acidic foods and certain types of clothes. From accurate intraoral clinical examination, white plaques were found in the dorsum of the tongue, hard palate and buccal mucosa, inaccurate and rough limits, and ulcerations throughout the labial edge and upper palate. Histopathology revealed a lichenoid reaction. Was instituted as pharmacological treatment, the use of systemic corticosteroids. Clinical follow-up of one year showed reduction of clinical symptoms, allowing to conclude that the clinical follow-up of this disease is necessary since its dubious malignant potential and diagnostic difficulty. Thus, early recognition of this disease allows instituting appropriate treatment with relief of anxiety of the patient and their family.

Efeitos da radioterapia sobre as condições bucais de pacientes oncológicos

This study evaluated the oral conditions of 50 cancer patients undergoing head and neck radiotherapy (RT). Clinical examinations were performed before treatment, immediately after 30 days after RT and 6 months after conclusion of RT. Periodontal conditions were evaluated using the criteria of the Periodontal Screening and Recording (SRP) and the need for dental treatment were determined. The presence of xerostomia, mucositis and other side effects of RT were also evaluated. Soon after the beginning of RT, the irradiated patients of radiotherapy developed severe mucositis, dermatitis, dysgeusia, xerostomia and, to a lesser extent, candidosis. After completion of radiotherapy, 68% of patients had level III or IV mucositis. It was found that the development of mucositis hinders oral hygiene and these factors contribute to exacerbate inflammation of periodontal tissues. The data from this study evidenced that the main cause of desertion of RT and of severity of sequelae of RT depends on the oral conditions of patients before starting treatment and the absence of previous dental treatment prior RT.

Implicações clínicas da doença de Lyme em região facial: revisão da literatura

Lyme disease (LD) is a systemic infl ammatory changes resulting from direct action and the immune response to the spirochete Borrelia burgdoferi transmitted by inoculation of the fl ow of the genus Ixodes tick and is most commonly found in North America, Europe and Asia. This disease can lead to facial and peripheral neurological manifestations, such as Bell’s palsy, eye changes, disorders in the temporo-mandibular joint in addition to paresthesia of superior and inferior alveolar nerves. In Brazil, the diagnosis of LD is primarily based on clinical presentation, the erythema migrans skin, and epidemiological information of the patient. Recognition of the onset of the DL by health professionals is essential for the correct antibiotic treatment preventing the progression of the disease, and also relevant preventive guidelines for those living or working in endemic areas.
