    Objetivo: A avaliação completa do seio maxilar (SM) é muito importante. A radiografia panorâmica é uma técnica de imagem acessível e bem estabelecida na prática odontológica; no entanto, imprecisões estão sempre presentes. Recentemente, a tomografia computadorizada de feixe cônico (TCFC) está emergindo como uma alternativa aceitável. Assim, o objetivo deste estudo foi comparar a precisão de diagnóstico proporcionada por imagens panorâmicas e imagens de TCFC para a avaliação de velamentos no seio maxilar. Métodos: Imagens panorâmicas e de TCFC de 51 pacientes foram selecionadas a partir de uma base de dados. As imagens foram aleatoriamente observadas por dois avaliadores calibrados em duas sessões de leitura para a presença ou ausência de velamentos no SM. Um terceiro radiologista oral avaliou as imagens fornecidas pela TCFC. Resultados: Dos 51 casos avaliados, 33 pacientes – 20 do sexo feminino e 13 do masculino – apresentaram velamentos no SM. Os resultados mostraram discordância significativa entre o diagnóstico dos avaliadores 1 e 2 e o do Avaliador 3 (76,5% e 60,8%), e também uma concordância razoável entre os avaliadores 1 e 2 (68,7%). Conclusões: As imagens tomográficas foram mais precisas na avaliação e localização de velamentos envolvendo o SM. As imagens panorâmicas foram capazes de identificar corretamente os velamentos, mas não localizá-los.Objective: Thorough assessment of the Maxillary Sinus (MS) is very important. Panoramic Radiography (PR) is an accessible and well-established imaging technique in dental practice, however, inherited inaccuracies are always present. Recently, cone beam computed tomography (CBCT) is emerging as an acceptable alternative. Thus, the aim of this study is to compare the diagnostic accuracy of panoramic and CBCT images for the evaluation of opacifications in the MS.Methods: Panoramic and CBCT images of 51 patients were selected from a data base. The images were randomly assessed by two calibrated evaluators in two reading sessions for the presence or absence of opacifications in the MS. A third oral radiologist evaluated the imaging findings provided by the CBCT and defined the gold standard.Results: Of the 51 evaluated cases, 33 patients, 20 females and 13 males, presented opacifications in the MS. The results showed significant disagreement between the diagnosis of the two evaluators and gold standard (76,5% and 60,8%) and also fair agreement between the evaluators (68,7%).Conclusions: CBCT images were more efficient to evaluate and locate opacifications involving the MS. Panoramic images were able to correctly identify but not to locate them

    Considering the role of epidemiological information in planning and effective interventions, the purpose of this study was to systematically review the epidemiology of squamous cell carcinoma in Brazil. We searched the PubMed, LILACS, BBO and Cochrane databases using keywords "oral squamous cell carcinoma", "oral squamous cell carcinoma", "oral squamous cell carcinoma" and their equivalents in English and Spanish, in combination with epidemiology, prevalence, frequency, and Brazil by 2018, excluding studies that did not address the epidemiology of this neoplasm or those conducted in other countries. The mean age of the patients was 56.6 years, with a higher prevalence in males 3.29: 1, mainly located in tongue, 42% and mouth floor 22%. Associated risk factors are tobacco (72.85%) and alcohol (66.65%). It was observed that 47% of patients present with regional metastases at the time of cancer discovery. According to the observed observational studies it can be concluded that the epidemiological data of Brazil are high in comparison to other countries, especially the number of metastases, indicating the late diagnosis of the diseas

    This study aimed to compare the periodontal condition between plaque and gingival indexes in 30 pairs of mother and child with mixed dentition, as well as to correlate the findings with some of their social and oral hygiene habits. Mother's and child's plaque and gingival indexes were recorded during clinical examination. Periapical and bitewing radiographs were taken in order to assess the presence of any pathologic bone loss. Questionnaires answered by the mothers were used to collect information regarding the mother's and the child's habits of tooth hygiene and the mother's job, instruction level and family income. The data collected from the mothers' group and from the children's group were statistically analyzed both separately and with the two groups together. From the statistical analyses (Pearson correlation test, student test and Covariance analysis), it was possible to conclude that there was a greater correlation between the plaque and gingival indexes in the mothers' group than in the children's group. No significant correlation between plaque and gingival indexes could be found between the pairs. Also, bone loss and plaque and gingival indexes in the children did not show any correlation. The mothers' plaque indexes increased with age and decreased when they flossed everyday and when they had a job. The children's plaque indexes were lower when they had their tooth hygiene done by their mothers, when the latter had declared that they flossed their children's teeth everyday, and also when the mothers had a job. Children's gingival indexes increased with age and decreased when they brushed their teeth more often, when their mothers had a job and when their mothers declared they are used to flossing every day.O objetivo deste estudo foi comparar a condição periodontal em 30 pares de mães e crianças com dentição mista, através dos índices de placa e gengival, bem como verificar sua correlação com alguns aspectos sociais e hábitos de higiene oral. No exame clínico foram registrados o índice de placa (IP) e índice gengival (IG) e, em seguida, foram realizadas tomadas radiográficas periapicais e interproximais que possibilitaram avaliar a possível presença de perdas ósseas em mães e crianças. Através de questionários, foram colhidas informações a respeito dos hábitos de higiene oral das mães e crianças, nível de escolaridade da mãe, se a mãe trabalhava fora e a renda familiar. Após análise estatística (Teste de Correlação de Pearson; test t de Student; Análise de Covariância), concluiu-se que houve maior correlação entre os índices de placa e gengival composto por adultos do que no grupo de crianças. Não foi encontrada correlação significante entre os índices de placa e gengival nos pares de mães e crianças. Não foi encontrada nenhuma correlação significante entre perda óssea e os índices de placa ou gengival dos pares. O índice de placa total das mães aumentou a idade e diminuiu quando a mãe utilizava fio dental diariamente e quando esta trabalhava fora. O índice gengival total das mães também foi reduzido quando elas trabalhavam fora. Houve redução no índice de placa total da criança quando a mãe a auxiliava durante a escovação, quando a mãe utilizava fio dental diariamente e quando esta trabalhava fora. O índice gengival total da criança foi maior com o aumento da idade e foi reduzido com aumento da sua freqüência de escovação, quando a mãe utilizava fio dental diariamente e quando a mãe trabalhava fora

    This study revisited three oral radiology centers (ORC) and screened the main clinical indications that justified the request for cone-beam computed tomography (CBCT) examination in Endodontics. The databases of three ORCs were searched for requests of CBCT exams taken for Endodontic purposes over the last two years. The extracted data consisted of the total number of CBCT exams, the clinical indication in the endodontic field that justified the CBCT exam, the outcome of each exam (from the report of Oral Radiologists), and demographic data of the patients. From the total CBCT exams (n = 4,583), nearly 13% (n = 611) were taken for Endodontic purposes. Most of the clinical indications were related to root fractures (65%) and periapical lesions/disease (24.1%). Radiologists’ reports hypothesized more often toward periapical lesion/disease (70.5%), root fracture (51.4%) and accidents/complications (25.2%). Some clinical indications significantly varied based on age. In particular, post-traumatic imaging and the investigation of root resorption were more common in young patients, while the prevalence of exams for the investigation of pulpal calcifications and root fractures increased with age. More interestingly, there was a significant disagreement between the clinical indication that justified the CBCT examinations and the outcomes retrieved from radiologists’ reports (p < 0.005). This study illustrates the broad spectrum of CBCT applications for the diagnosis, treatment planning and follow-up in Endodontics. Attention is necessary to the disagreements between clinical indications and imaging outcomes, especially because certain conditions in the routine Endodontics are only visible with the aid of advanced tools.Este estudio revisitó tres centros de radiología oral (CRO) y cribo las principales indicaciones clínicas que justificaron la solicitud de examen por tomografía computarizada de haz cónico (CBCT) en endodoncia. Se realizaron búsquedas en las bases de datos de tres CRO en busca de solicitudes de exámenes CBCT realizados con fines endodónticos durante los últimos dos años. Los datos extraídos consistieron en el número total de exámenes CBCT, la indicación clínica en el campo endodóntico que justificó el examen CBCT, el resultado de cada examen (del informe de los radiólogos orales) y los datos demográficos de los pacientes. Del total de exámenes CBCT (n = 4583), casi el 13% (n = 611) se tomaron con fines de endodoncia. La mayoría de las indicaciones clínicas se relacionaron con fracturas radiculares (65%) y lesiones / enfermedades periapicales (24,1%). Los informes de los radiólogos plantearon con mayor frecuencia la hipótesis de lesión / enfermedad periapical (70,5%), fractura de raíz (51,4%) y accidentes / complicaciones (25,2%). Algunas indicaciones clínicas variaron significativamente según la edad. En particular, las imágenes postraumáticas y la investigación de la reabsorción radicular fueron más comunes en pacientes jóvenes, mientras que la prevalencia de exámenes para la investigación de calcificaciones pulpares y fracturas radiculares aumentó con la edad. Más interesante aún, hubo un desacuerdo significativo entre la indicación clínica que justificaba los exámenes CBCT y los resultados obtenidos de los informes de los radiólogos (p <0,005). Este estudio ilustra el amplio espectro de CBCT para el diagnóstico, la planificación del tratamiento y el seguimiento en endodoncia. Es necesario prestar atención a los desacuerdos entre las indicaciones clínicas y los resultados de las imágenes, especialmente porque ciertas condiciones en la endodoncia de rutina solo son visibles con la ayuda de herramientas avanzadas.O presente estudo revisitou três centros de radiologia odontológica (ORC) e rastreou as principais indicações clínicas que justificaram a solicitação do exame de tomografia computadorizada de feixe cônico (TCFC) em Endodontia.

A maioria das indicações clínicas foi relacionada a fraturas radiculares (65%) e lesões / doenças periapicais (24,1%). Os laudos dos radiologistas levantaram a hipótese mais frequentemente de lesão / doença periapical (70,5%), fratura radicular (51,4%) e acidentes / complicações (25,2%). Algumas indicações clínicas variaram significativamente com base na idade. Em particular, a imagem pós-traumática e a investigação de reabsorção radicular foram mais comuns em pacientes jovens, enquanto a prevalência de exames para investigação de calcificações pulpares e fraturas radiculares aumentou com a idade. Mais curiosamente, houve uma discordância significativa entre a indicação clínica que justificou os exames de TCFC e os resultados obtidos dos relatórios dos radiologistas (p <0,005). Este estudo ilustra o amplo espectro de aplicações da TCFC para o diagnóstico, planejamento de tratamento e acompanhamento em Endodontia. É preciso atentar para as divergências entre as indicações clínicas e os desfechos de imagem, principalmente porque certas condições da rotina da Endodontia só são visíveis com o auxílio de ferramentas avançadas

    Exploring de association between feeding habits, non-nutritive sucking habits, and malocclusions in the deciduous dentition

    Get PDF
    Background: This study aimed to explore the association between feeding habits, non-nutritive sucking habits, and malocclusions in deciduous dentition. Methods: A cross-sectional observational survey was carried out in 275 children aged 3 to 6 years and included clinical evaluations of malocclusions and structured interviews. Statistical significance for the association between feeding habits and the development of malocclusion was determined using chi-square and Fisher's exact tests. In addition, odds ratio (OR) calculations were used for intergroup comparisons. Controlling for confounders was adjusted by excluding children with non-nutritive sucking habits. Results: The results indicated that there were no significant relationships between exclusive breastfeeding or bottlefeeding and the presence of any type of malocclusion (p>0.05). There was also no significant association between breastfeeding or bottlefeeding duration and malocclusion (p>0.05). In addition, it was observed that exclusive breastfeeding had a protective effect and diminished the risk of acquiring non-nutritive sucking habits (p=0.001). Conclusions: There was no association between feeding habits and malocclusions in the deciduous dentition in this sample of children. Exclusive breastfeeding reduced the risk of acquiring non-nutritive sucking habits

    Self‐medication and pain catastrophizing in patients with myofascial pain : are they related?

    Get PDF
    Evidence shows that acute symptoms of temporomandibular dysfunction (TMD) would eventually lead to chronicity and self‐medication would play a significant interfering role on such dynamics (Dias, Bastos, Alves, & Leite, 2019; Pastore, Goulart, Pastore, Prati, & de Moraes, 2018). Furthermore, some authors concluded that both propensity to catastrophize and depression contribute to the progression of chronic temporomandibular muscle and joint disorders (Velly et al., 2011). Hence, the aim of this study was to assess the relationship between the habit of self‐medicating and the propensity to catastrophize pain in a clinical population with myofascial pain (MP).© 2019 John Wiley & Sons A/S.

    Get PDF
    O objetivo foi o de avaliar, através da análise de radiografias panorâmicas, a ocorrência do pseudocisto antral na cidade de Volta Redonda, Rio de Janeiro, associando condições geográficas e poluição do ar. Duas mil e quatrocentas radiografias panorâmicas pertencentes ao arquivo do RADIOCENTRO - Centro Odontológico de Documentação Ortodôntica localizado na cidade de Volta Redonda, obtidas no período de janeiro a dezembro de 2008, foram analisadas em relação à presença de imagens radiográficas compatíveis com Pseudocisto Antral. Concluiu-se que a prevalência média encontrada (6,83%) está dentro dos índices relatados na literatura (variação de 1,4 e 9,6%), porém quando estudadas as condições geográficas do município e poluição do ar, verificou-se que a incidência nos bairros localizados na margem esquerda em relação ao Rio Paraíba do Sul (8,67% e 17,5%) esteve acima da média relatada na literatura, indicando a participação da poluição do ar na gênese do pseudocisto antral

    Methodologic quality and risk-of-bias in systematic reviews of healthcare interventions: a review of methods

    Get PDF
    OBJECTIVE: To compare the characteristics of systematic reviews of healthcare interventions that assessed or did not methodologic quality/risk-of-bias of included studies. Additionally, to analyze methodologic features of those assessing the methodologic quality/risk-of-bias. METHODS: PubMed database was searched. From 25,571 systematic reviews retrieved, a random sample of 1,025 was screened. Frequencies were used to describe outcomes. Unadjusted and adjusted logistic regressions were performed to test the associations with methodologic quality/risk-of-bias results assessment. In a second analysis, systematic reviews that assessed methodologic quality/risk of bias were dichotomized according to the design of included studies (randomized clinical trials-only versus non-randomized studies of intervention or a combination of both). RESULTS: 303 systematic reviews were fully analyzed. Methodologic quality/risk of bias was assessed by 278 (92%). Methodologic quality/risk-of-bias assessment was associated with a higher number of databases searched (>4, P= 0.008), the presence of meta-analysis (P= 0.005), and the design of included studies (randomized clinical trials-only, P= 0.042). The chance of using a suitable tool and a tool designed for risk-of-bias assessment rather than methodologic quality was higher for randomized clinical trials-only systematic reviews (P4). The most used tool was Cochrane’s RoB Tool, with no clearly defined rating system. Methodologic quality/risk-of-bias assessment methods description, results, and impacts on meta-analysis, the certainty of evidence, and systematic reviews’ results are still to be consistently addressed.
