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...

Root canal calcification is characterized by the deposit of mineralized tissue along the canal walls, it is usually asymptomatic and is detected incidentally during a radiographic examination. Teeth that suffer from this process may develop apical periodontitis over time and consequently require endodontic treatment. The pulp chamber and root canal space may be partially or completely obliterated, increasing the risk of procedural errors during root canal preparation. With the advent of cone beam computed tomography (HCCT), teeth can be visualized three-dimensionally, and the superimposition of anatomical structures is eliminated. This review aims to present the considerations for the diagnosis and management of calcified root canals. An electronic search was carried out in PubMed, SciELO, Google Scholar and Science Direct, using the keywords cone-beam computed tomography/endodontics /pu...

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...

Partial or total perforation of the articular disc is mainly observed in the final stage of temporomandibular disorder. Magnetic resonance imaging (MRI) is considered the gold standard for the diagnosis of joint pathologies; MRI arthrography consists of the infiltration of a contrast medium into a joint, being Gadolinium chelates the most employed medium, however, possible harmful effects have been associated with its use. The aim of this work was to evaluate a case of perforation of the articular disc of the temporomandibular joint by MRI arthrography using physiological solution (NaCl 0.9%) as contrast medium. MR images were obtained with a STIR (Short Tau Inversion Recovery) weighted pulse sequence in the sagittal and coronal planes at maximum mouth opening, after the injection of the physiological solution in the superior articular space. The communication of both articular spaces wa...

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...

Unilateral condylar hyperplasia is a non-neoplastic and self-limiting overgrowth of the mandibular condyle that usually begins during puberty, predominates in women and is considered an aberration of the normal growth mechanism of the condyle. This abnormal growth continues until the mid-20s and produces mandibular prognostism, facial and occlusal asymmetry with progressive displacement of the mandible to the contralateral side. The purpose of this report was to describe the cases of two female patients (23 and 25 years old) with unilateral condylar hyperplasia treated with high condylectomy and orthognathic surgery, with emphasis on clinical and imaging aspects and late post-surgical follow-up. Both patients presented satisfactory cosmetic results, without pain / noise related to the temporomandibular joint, mouth opening within the normal range, and class I canine and molar relationshi...

Introducción: La fotobiomodulación con láser diodo se ha aplicado como una técnica no invasiva para tratar los síntomas de la articulación temporomandibular (ATM), especialmente en el alivio de condiciones dolorosas agudas. Objetivo: Evaluar el efecto de la fotobiomodulación en el manejo del dolor agudo y la apertura bucal en pacientes con trastorno de la ATM. Metodología: Fueron incluidos 12 pacientes diagnosticados según los criterios de diagnóstico para los trastornos temporomandibulares (DC/TMD) para aplicaciones clínicas y de investigación de la Red del Consorcio Internacional RDC/TMD de la International Association for Dental Research y el Grupo de Interés Especial en Dolor Orofacial de la International Association for the Study of Pain, tras la firma del consentimiento informado. Todos los pacientes fueron irradiados usando un láser diodo dual Gemini EVO Ultradent®,...

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...
