“…Assessed on panoramic radiographs, MCI is widely advocated as appropriate for detecting osteoporotic alterations. 18,20,[34][35][36] BMI 24,37 and age are strongly correlated with BMD status, 23,38,39 although other factors may still influence BMD, such as sunlight exposure, sedentary lifestyle, body type or excessive coffee intake. 40 Actively studied in the literature, these main points were highlighted to assess Brazilian postmenopausal women with different ethnicities.…”

“…The information provided by a simple HU measurement can be valuable to detection of patients who need DXA examination referral. 8 In Dentistry, many researchers advocate that dental radiographs are useful to osteoporosis screening 2,9,10 as morphologic alterations in jaws are observed. 11 Considering CT, the correlation between the BMD of the cervical vertebrae and the lumbar vertebrae, also between the BMD of the cervical vertebra and mandible, has already been stablished.…”

| Objectives: to evaluate the correlation of the bone mineral density (BMD) from maxilla and mandible with that of the cervical vertebrae, using Hounsfield units (HU) and multislice computed tomography (CT) to verify whether CT could be a useful osteoporosis screening tool. Methods: 79 multislice CT examinations from patients who underwent CT examinations of maxilla, mandible and cervical vertebrae simultaneously were included. The following left and right anatomical regions were assessed: mandible ramus; mandible head; the area below the inferior first molar and the area below the upper cuspids. HU were measured in each area using a 0.1 cm region of interest (ROI) positioned in the center of the slice. Results: a significant correlation between the cervical spine and the posterior region of the mandible was found, as well as a significant correlation between the anterior maxilla and the cervical spine. However, no correlation was found between the cervical spine and other parts of the mandible, such as ramus and head of mandible. Conclusions: As anterior maxillary bone and posterior mandible bone HU values correlate with cervical bone HU values, this examination may be applied as osteoporosis screening tool.

Métodos: 79 exames de tomografia computadorizada multislice de pacientes que foram submetidos a CTs de maxila, mandíbula e vértebras cervicais simultaneamente foram incluídos. As seguintes regiões anatômicas esquerda e direita foram avaliadas: ramo da mandíbula; cabeça mandibular; a área abaixo do primeiro molar inferior e a área abaixo das cúspides superiores. HU foram medidos em cada área usando uma região de interesse (ROI) de 0.1cm posicionada no centro do corte tomográfico. Resultados: Foi encontrada uma correlação significativa entre a coluna cervical e a região posterior da mandíbula, bem como uma correlação significativa entre a região anterior da maxila e a coluna cervical. No entanto, nenhuma correlação foi encontrada entre a coluna cervical e outros locais da mandíbula, como o ramo mandibular e a cabeça. Conclusões: Como os valores de HU do osso anterior e posterior da mandíbula se correlacionam com os valores de HU do osso cervical, este exame pode ser aplicado a ferramentas de rastreio da osteoporose.

“…Many researchers advocate its use for screening for osteoporosis [4,8,[15][16][17][18][19][20][21][22][23][24] by the fact that the mandibular cortical bone may reflect changes in bone architecture of other sites from skeleton [4,12,15].…”

OBJECTIVE: To compare assessment of panoramic radiographs using Mandibular Cortical Index (MCI) by a radiologist with experience and two dentists with no experience in this index using original radiograph images and inverted images. METHODS: 64 panoramic radiographs were analyzed by three observers: a radiologist with previous experience in MCI and two trained dentists with no previous experience. First, the original images were assessed by the radiologist and defined as the gold standard. Then, dentists received training in the MCI. Assessment results obtained from the three observers were analyzed. RESULTS: When compared results from the experienced radiologist to positive and inverted images, no statistical significant difference was found. When considering the two trained observers, we found that inverted images had a lower agreement between the gold standard original images. CONCLUSION: We concluded that, within the limitations of this study, inverted radiographs are not recommended for MCI assessment.Key words: Osteoporosis; Panoramic radiography; Dental digital radiography; Software tools O uso de radiografias panorâmicas modificadas por um software de acesso gratuito na determinação do Índice da Cortical Mandibular RESUMO OBJETIVO: Comparar a avaliação de radiografias panorâmicas usando o Índice Cortical Mandibular (ICM) por um radiologista com experiência e dois cirurgiões dentistas sem experiência neste índice usando imagens de radiografia originais e imagens invertidas. METODOLOGIA: 64 radiografias panorâmicas foram analisadas por três observadores: um radiologista com experiência prévia com o ICM e dois dentistas treinados sem experiência prévia. Inicialmente, as imagens originais foram avaliadas pelo radiologista e definidas como padrão-ouro. Então, os dentistas receberam treinamento para aplicar o ICM. Os resultados da avaliação obtidos dos três observadores foram analisados. RESULTADOS: Qquando comparados os resultados do radiologista experiente em imagens positivas e invertidas, não foi encontrada diferença estatística significante. Ao considerar os dois observadores treinados, descobrimos que as imagens invertidas apresentaram menor concordância com o padrão ouro. CONCLUSÃO: Concluímos que, dentro das limitações deste estudo, as radiografias invertidas não são recomendadas para a avaliação do ICM.Palavras-chave: Osteoporose; Radiografia panorâmica; Radiografia dentária; Software 84Rev Odonto Cienc 2017;32(2):83-87Open access software and Mandibular Cortical Index | Munhoz et al.
