In dental practice, the use of imaging has increased over the years, generating an increase in the radiation dose for the dental patient. One factor under discussion is the amount of dose used in patients, men, women and children, at different stages of their life, due to the scientific evidence of the harmful effects of ionizing radiation. This review of the literature analyzed the characteristics of radiation and its effects in relation to the doses administered, and its equivalences in dental practice in panoramic periapical radiographs and cone beam tomographies. A search of the literature was carried out in the main information sources such as Medline (via PubMed), SEVIER, SCIELO, and LILACS, using the search terms with a date limitation of the last 10 years. The selected articles had to include information regarding the keywords used, including "Dental Offices, Radiation Dose, X-Rays, Ambulatory Care."
Imaging studies used as aid in the diagnosis of cleidocranial dysplasia. A review
(2021) Laura A. Granado-Abasto; Jhoana Mercedes Llaguno-Rubio; Gustavo Adolfo Fiori-Chíncaro; Paola Elena Medina Ocampo
Cleidocranial dysplasia (CCD), also known as Marie-Sainton syndrome, is a rare disorder of autosomal dominant type that presents specific characteristics at the skeletal and dental level. The diagnosis of CCD is based on clinical and radiographic findings. Panoramic, cephalometric and anterior poster radiographs have been used for its diagnosis in dentistry. However, these radiological techniques have limitations, and advances in technology with new imaging studies such as magnetic resonance imaging (MRI) and ultrasound have emerged, contributing to the diagnosis of CCD. Therefore, the aim of this review was to identify and describe current imaging studies that contribute to both the diagnosis and adequate and efficient treatment planning of CCD, and describe the clinical and radiographic characteristics of patients with this syndrome.
Los restos de Malassez, vida y destino en los tejidos odontogénicos. Una revisión de la literatura
(2020) Paola Elena Medina Ocampo; Gustavo Adolfo Fiori-Chíncaro
Los restos epiteliales de Malassez son células que se encuentran alrededor de las raíces de las piezas dentarias y forman parte de los tejidos del ligamento periodontal, donde se disponen en forma de red. Las funciones que desempeñan no son muy específicas; sin embargo, se demostró su participación en el mantenimiento del espacio del ligamento periodontal, la regeneración del tejido periodontal, la regeneración del cemento, entre otros. Además, tienen capacidad de diferenciarse en otros linajes celulares, lo que demuestra su capacidad como células madres, y el papel más conocido que tienen es su participacipación y proliferación en la formación de diversas patologías, como quistes y tumores odontogénicos.
Uso de herramientas de imagenología actual para el estudio del mixoma odontogénico. Una revisión de la literatura
(2022) Rocío Vidales-Miranda; Gustavo Adolfo Fiori-Chíncaro; Ana María Agudelo-Botero; Jhoana Mercedes Llaguno-Rubio
Odontogenic myxoma (OM) is currently classified as a benign tumor of ectomesenchymal origin, observed between the second and fourth decade of age, with a predilection in women and predominance in the mandibular region, composed of rounded and angular cells embedded in an abundant myxoid stroma, of aggressive biological behavior, having the characteristic of being locally infiltrative. Tumor cells spread in the intratrabecular space beyond the bone limit, making it difficult to determine the edge of the tumor, even without cortical continuity, presenting intermittent direct contact with soft tissue; the appearance can be unilocular (small lesions), or commonly the typical image is that of a destructive lesion with poorly defined borders with a multilocular growth pattern, for which the use of advanced medical images such as Cone Beam Computed Tomography (CTHC), Computed Tomography (CT), Magnetic Resonance Imaging (MRI), are useful to establish an adequate diagnosis with the ability to point out the characteristics of OM with precision and three-dimensional perspective. This review presents a systematic analysis of the types of imaging tools currently used for the study of OM.
