Resumo: | Abstract Introduction: Soft tissues modify radiation absorption and increase dispersion. It can also influence the density and the contrast of the film, and therefore, the diagnosis accuracy. In order to estimate the relative risk of cancer associated with induction by radiation, it is important to measure radiation doses at organs and tissues. Objective: to evaluate salivary glands entrance dose, with two digital devices in a head and neck phantom. Methodology: Periapical incidences simulations of incisors were conducted and compared with two digital periapical radiological equipment (Kodak® 2200 Intraoral X-ray System) which have similar characteristics. A dry bone skull prototype and an equivalent human tissue material with wax were used. To measure the organ entrance dose: parotid gland and sublingual glands, it was used a solid-state sensor from Radcal®, Accu-Gold® for diagnostic radiology and an ionization chamber from Radcal®, Accu-Gold®, where effective doses were measured in the equipment and in the sensor and then compared. Results: in parotid glands were 0.033 mSv and in sublingual 0.388 mSv. Conclusion: It is important to highlight from the results the importance of using low doses of radiation and the appropriate equipment positioning in order to perform periapical radiological incidences in maxillary and mandibular regions. If the beam it is not corrected positioned, an increase in the radiation dose to organs can occur near to the area of study. Keywords: Radiography, dental. Radiation dosage. Salivary glands |

Salivary glandsIntrodução: Os tecidos moles alteram a absorção de radiação e aumentam a dispersão, e podem influenciar o contraste e a densidade do filme e, em consequência, a precisão do diagnóstico. A medida da dose de radiação sobre órgãos e tecidos é essencial para a estimativa do risco relativo de câncer associado à indução por radiação. Objetivo: avaliar dose de entrada em glândulas salivares, com dois equipamentos digitais em um fantoma de cabeça e pescoço. Metodologia: Realizou-se a simulação de incidências periapicais de dentes incisivos, comparando-se dois equipamentos radiológicos periapicais digitais da marca Kodak® 2200 Intraoral X-ray System de características similares. Utilizou-se um protótipo de crânio contendo osso seco e material equivalente a tecido humano com parafina. Para a medição das doses de entrada em órgão: glândulas parótidas e glândula sublingual utilizou-se um sensor de estado sólido marca Radcal® Accu-Gold® para radiodiagnóstico e uma câmara de ionização marca Radcal® Accu-Gold®, onde foram medidas as doses efetivas e comparadas as indicadas no equipamento com as capturadas no sensor. Resultados: em glândulas parótidas foram 0,033 mSv e 0.388 mSv em sublingual. Conclusão: Dos resultados obtidos e analisados, destaca-se a importância da utilização de doses baixas de radiação e do adequado posicionamento do equipamento para realizar as incidências radiológicas de exames periapicais em região maxilar e mandibular, uma vez que, não estando o feixe na posição exata indicada para essas incidências, pode ocorrer um aumento de dose de radiação nos órgãos próximos à região estudada.Submitted by ROBERTO PAULO CORREIA DE ARAÚJO (ppgorgsistem@ufba.br) on 2017-06-20T13:22:57Z No. of bitstreams: 1 4_v.13_3.pdf: 1390287 bytes, checksum: 75de73d52225f0820cf81b91305cac58 (MD5)Made available in DSpace on 2017-06-20T13:22:57Z (GMT).
