Objetivo: El objetivo de este estudio fue comparar las características morfológicas de la articulación temporo mandibular (ATM) y relacionarla con pacientes de clase I versus clase II esquelética. Materiales y métodos: Se realizó un estudio retrospectivo, transversal y descriptivo en una muestra de 188 tomografías computarizadas de haz cónico (TCHC) y sus radiografías cefalométricas de pacientes clase I y II esquelética, de ambos sexos, entre 15 a 65 años. Se analizaron variables de forma, altura, ancho del cuello y dimensiones en sentido medio-lateral, y antero-posterior del cóndilo, mediante análisis de regresión lineal múltiple, Test de U de Mann Whitney y la prueba de Chi cuadrado. Resultados: Para las variables edad, relación esquelética (ANB y Wits) entre la clase I y clase II, se encontraron diferencias estadísticamente significativas (p<0.05). Para las variable...

In medicine, ultrasound is especially useful to evaluate intrauterine development, cyst behavior, and internal organs, but the use of ultrasound in dentistry has only recently been explored and used in the daily routine diagnostic methods in clinical dental practice. The growing interest in the useof ultrasound as a diagnostic and therapeutic method in dentistry has led to studies investigating its benefits in relation to accessibility, cost and innocuousness to health. This review describes the current use of ultrasound in different dental specialties and compares it with other diagnosticmethods.

Osteomas are benign osteogenic lesions derived from compact or spongy bone. They are characterized by their slow growth and appear more frequently between 20 and 50 years of age, with a higher prevalence in men than in women. These lesions are clinically asymptomatic and canbe found in the craniofacial region, particularly in the paranasal sinuses and the mandible, and may have a central, peripheral or extraosseous presentation. Multiple osteomas are related to Gardner's Syndrome. Treatment of osteoma is surgical when complications develop. Imaging studies such as panoramic radiography and cone beam computed tomography are the modalities most widely used to determine the location, extent, and anatomical relationships of the lesion. Imaging features may present as a bony excretion of compact, spongy, or mixed bone. Adequate knowledge of these lesions allows adequate diagnosis and better t...

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), ELSEVIER, 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...
