Objective: tomography (MCT). Materials and methods: This was a descriptive, retrospective cross-sectional study. The sample was made up of 238 MCT studies performed in patients of both sexes between 20 to 87 years of age, with indication of tomography of the craniofacial complex. The length of the SHC was measured in lateral views of 3D volumetric reconstructions. The distribution of these cases was obtained according to age, sex, laterality, type, and the reason for the examination. Results: The mean length of the SHC was 30.66 ± 10.58 mm. Of the total sample, 127 (53.4%) individuals showed an elongated SHC; of these, 63.8% were women and 64.6% of the patients presented a bilateral compromise of the complex. Most of the subjects with an elongated SHC were between 30 and 59 years old. The type of ossification most frequently found was type I (continuous elongation). Regarding the reason...

Hyperplasia of the coronoid process is a rare alteration that is characterized by the exaggerated and progressive development of said process over periods of months or years, both in height and volume, which finally causes mandibular hypomobility. It is important to highlight the importance of imaging for the correct diagnosis and treatment of said entity, taking into consideration the great variety of differential diagnoses that can occur. In this sense, conventional radiographs constitute a basic and indispensable tool for approaching the diagnosis. However, it is actually the CT scan that offers the greatest precision. The case of a 14-year-old male patient is presented, with no contributing medical history, who was referred for presenting progressive opening limitation since childhood, for which, after clinical and imaging evaluation, he was treated with total bilateral coronoidectom...

Unicystic Ameloblastoma (UA) accounts for approximately 6% of all ameloblastomas. They are often observed during the second decade of life, without a predilection for gender, with 90% of the lesions occurring in the jaw and related to an unerupted tooth. Unicystic ameloblastoma shows clinical and radiographic features similar to maxillary cysts but histologically evidences ameloblastic epithelium. The lesion has a less aggressive biological behavior than solid ameloblastoma, with a lower recurrence rate compared with conservative treatment, however, a radical therapeutic is recommended for the intramural variant. The aim of the present work was to describe a case of UA located in the maxilla of a 26-year-old male patient, who showed an increase in volume in the right hemiface of five months of evolution. The histopathological examination of the specimen obtained by the incisional biopsy ...

El ameloblastoma uniquístico (AU) representa aproximadamente el 6% de todos los ameloblastomas y es frecuentemente encontrado durante la segunda década de la vida, sin predilección por sexo, se localiza en la mandíbula en relación a un diente no erupcionado, demuestra características clínicas y radiográficas similares a los quistes maxilares, pero evidencia histológicamente epitelio ameloblástico. Aunque el AU tiene un comportamiento menos agresivo que el ameloblastoma sólido, se recomienda un tratamiento radical para la variante intramural debido a su naturaleza infiltrativa, lo que tiende a potenciarse cuando se localiza en el maxilar superior. El objetivo del presente trabajo fue describir un caso de ameloblastoma uniquístico intramural localizado en el maxilar superior de un paciente masculino de 26 años de edad, quien presentaba un aumento de volumen indoloro en hemicar...

Objective: To evaluate the influence of age, sex and dental status on radio-morphometric indexes of the mandible, obtained from panoramic radiographs of a Venezuelan adults. Methods: The sample consisted of 156 digital panoramic radiographs of individuals of both sexes (78 men and 78 women), with ages between 20 and 81 years old, where the following indexes were measured by ImageJ software: MC=thickness of the mandibular cortex, MRH= mental region height, ARR=degree of alveolar ridge reabsorption, PMI=panoramic mandibular index, AGI=antegonial index, GI=gonial index, MRH=- maximum height of the ramus, GA=gonial angle. Descriptive statistics, Spearman correlations and differences in means were obtained using the Mann-Whitney test. Results: There was a tendency to measurement values reduction for the indices obtained from age groups, for both sexes, as well as statistically significant dif...

The Stafne bone cavity (SC) has been described as an oval radiolucence, with defined and corticalized edges located below the jaw duct between the first molar and the angle of the jaw. Atypical cases of presentation of the cavity in lobed form with irregular, sclerotic or incomplete margins, as well as an unusual location require the use of imaging methods that make possible a differential diagnosis, avoiding an invasive procedure. The purpose of this work was to describe a case of SC in a 74-year-old male patient, with a history of prostate cancer. Cone beam computed tomography images showed an open cavity toward the lingual table below the mandibular canal. Magnetic resonance imaging and multi-cut computerized tomography allowed identifying the defect content, found adipose tissue. The radiographic examination of an atypical SC should be complemented with tomographic and magn...

Peri-implantitis (PI) is the inflammatory reaction of the peri-implant mucosa, accompanied by the progressive loss of supporting bone around the implant, which can compromise its stability, function and aesthetics. It is diagnosed by radiographic measurement of the alveolar bone level, with or without clinical symptoms of inflammation and a probing depth greater than 4 mm. The objective of this work was to review the scientific evidence on the prevalence, etiology, predisposing factors, clinical behavior and imaging characteristics of PI. An electronic search was carried out in Google Scholar, PubMed and Scielo, considering the period between 2010-2022, and a total of 40 articles were selected. It is concluded that the main etiological agent of PI is the biofilm, however, its appearance and severity may be associated with the presence of predisposing factors such as Diabetes Mellitus, sm...

The coronavirus disease 2019 caused by SARS-CoV-2, was declared a pandemic by the World Health Organization on March 11, 2020. Direct transmission occurs by respiratory route, while indirect transmission requires contact with the buccal, nasal or ocular mucosa with contaminated surfaces. In the presence of asymptomatic carriers that transmit the virus, all patients should be treated as possible sources of infection. In dental care, close contact with the patient and saliva puts staff at high risk for cross infection; The practice of dentomaxillofacial radiology in radiological centers or in the dental clinic is not exempt from this risk. The objective of the present literature review was to develop biosafety recommendations for the practice of dentomaxillofacial radiology. The recommendations related to areas and equipment indicate the importance of keeping these areas ventilated, with t...

Cone Beam Computed Tomography offers highly precise 3D images ideal for diagnosis and case planning, although this imaging method involves the use of high doses of radiation. When considering the optimization principle, radiation dose reduction methods aim to modify the technical parameters of the equipment to obtain an ideal combination between dose and image quality. This is important in the pediatric patient because the highest levels of risk are associated with X-ray exposure in this age group. We present the case of an 11-year-old female patient is presented, in which a low-resolution protocol is used to locate the maxillary retained canines. The advantages and practical application of this imaging study method are analyzed by performing variations in exposure parameters. Supported by tomographic images, the surgical procedure is carried out to subsequently a guided eruption, achiev...
