Unlabelled: Several studies have evaluated the parameters of normality of the sella turcica (ST), which is important to face different craniofacial syndromes that may affect this structure. Therefore, this research summarized the scientific evidence on the role of ST in the sex estimation of non-syndromic individuals. The research protocol was registered (Prospective International Registry of Systematic Reviews # CRD42021256469), followed by an electronic search in six databases (PubMed, LILACS, Web of Science, Scopus, EMBASE, and LIVIVO) and gray literature (Google Scholar and OpenGrey).

The oral mucositis is a mucosal alteration that usually arises from oncological treatments, such as chemotherapy, and it is characterized as an inflammatory process. The aim of this study is to demonstrate the chromatographic constitution of Andiroba oil, comparing and evaluating Andiroba oil and laser scarring efficiency in treatments of oral mucositis in hamsters. These animals were submitted to 5-Fluorouracil.

This systematic review aimed to answer the question, "Are paranasal measurements obtained with multislice computed tomography able to accurately estimate sex?" This PROSPERO-registered systematic review included six databases and gray literature. Meta-analysis of linear and volumetric data was performed using a random-effects model, mean differences (MDs), and inverse variance. The QUADAS-2 tool-related risk of bias (RoB) and certainty evidence (GRADE approach) were assessed.

Objectives: To evaluate the accuracy of the measurements of the maxillary sinus (MS) and frontal sinus (FS) in sex estimation among Brazilian adults using multislice computed tomography (MCT) and to develop and cross-validate a new formula for sex estimation.
Methods: The present cross-sectional research was conducted in two phases: (1) development of a formula on the basis of the measurements of both the sinuses (50 males and 50 females); and (2) validation study (20 males and 20 females). The linear measurements (height, width and diameter) were assessed using the RadiAnt DICOM software.

Ethno-pharmacological Relevance: The Carapa guianensis Aubl, popularly known as andiroba, is a large tree of the Meliaceae family, commonly found in the Amazon region. The oil extracted from its seeds is recognized in traditional medicine and has high anti-inflammatory and analgesic potential, which are the basic prerequisites for a therapeutic agent that can be used in the treatment of oral mucositis (OM). Moreover, the aforementioned oil has antimicrobial, antiallergic, and parasiticidal actions and is effective in the management of cutaneous and muscular dysfunctions.

Computed tomography facial scans of the 25 patients submitted for Le Fort I were divided into two groups: Group 1-S53P4 group and Group 2-without grafting. CT scans were analyzed in the immediate postoperative period (T1) and 6 months later (T2), for linear bone gap measurements, tomographic radiodensity and behavior of the maxillary sinus.

It has high rates of metastasis and recurrence and is associated with significant morbidity. During the progression of ACC, the oxygen concentration is reduced in specific areas of the tumour microenvironment, leading to intratumoural hypoxia.

Cone beam computerized tomography (CBCT) is an excellent tool in the examination of these structures. The present study aimed to evaluate the maxillary, frontal and sphenoidal sinuses through a discriminant analysis to determine the sex correlations with foramen magnum measurements were also assessed.

Cancer can have a number of causes, such the activation of oncogenes, the inactivation of tumor-suppressing genes, mutagenesis provoked by external factors, and epigenetic modifications. The development of diagnostic tools and treatments using a molecular biological approach permits the use of sensitive, low-cost, noninvasive tests for cancer patients.

Objectives: The aim of this study was to investigate the healing activity of andiroba (Carapa guianensis Aubl.) against oral mucositis (OM) induced by 5-fluorouracil in golden Syrian hamsters.
Materials And Methods: A total of 122 animals were randomized and divided into six groups: andiroba oil 100%, andiroba oil 10%, andiroba oil 10% refined, no treatment group, all n = 28; and negative control (NC) and cyclophosphamide (CPA) groups, both n = 5.

Introduction: The objective of this study was to establish the anatomical relation between nasal septum deviation (NSD) and oropharynx volume in different facial patterns using cone beam computed tomography (CBCT).
Methods: Ninety CBCT examinations were analyzed. InVivoDental software was used to evaluate cephalometric image reconstructions in terms of facial type, determined from cephalometric measurements indicative of growth direction; the presence of NSD was also evaluated.
Purpose: Computed tomograms of the mandibles of 285 patients with indications for dental implants were evaluated at a private clinic.
Materials And Methods: This study involved the evaluation of 285 cone-beam computed tomograms of patients 50 to 75 years of age who were referred to the clinic for the evaluation for implant placement images with visible C3 and C5 vertebrae that were obtained using the same I-Cat tomographic device (Imaging Sciences-Kavo, Hatfield, PA). Atheromas in the carotid space were visualized using paraxial images.
Panoramic radiographs are a relatively simple technique that is commonly used in all dental specialties. In panoramic radiographs, in addition to the formation of real images of metal objects, ghost images may also form, and these ghost images can hinder an accurate diagnosis and interfere with the accuracy of radiology reports. Dentists must understand the formation of these images in order to avoid making incorrect radiographic diagnoses.

Methodology: A total of 100 cone beam computed tomography (CBCT) examinations were collected from the files of a dental clinic in the Municipality of Belém, Pará, Brazil, and analyzed to identify the site of bifurcation, the diameter of CS right after such bifurcation and in its terminal portion as well as the direction of its course and the distance to the alveolar bone crest region. The anatomical views were evaluated using InVivoDental software on sagittal, axial, and coronal sections, and the results were submitted to Fisher's exact test, Kendall correlation coefficients, Mann-Whitney tests, and T tests.
Hutchinson-Gilford progeria syndrome (HGPS) is a rare dysmorphic syndrome characterized by several features of premature aging with clinical involvement of the skin, bones, and cardiovascular system. HGPS has an estimated incidence of one in four million to one in eight million births. The main clinical features of HGPS include short stature, craniofacial dimorphism, alopecia, bone fragility, and cardiovascular disorders.

Objective: This study investigated the prevalence of calcified carotid artery atheromas (CCAAs) in panoramic radiographs of HIV-positive patients.
Study Design: A retrospective cross-sectional study was performed to evaluate the presence of CCAA in 300 panoramic radiographs. Qualitative variables were compared using the χ(2) test or Fisher exact test, as needed.
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare condition that occurs normally in the anterior maxilla of infants aged <1 year. The use of clinical and imaging tools for MNTI is extremely important to prevent problems with function as well as the aesthetic features in a breastfeeding child. Brazil is a multiethnic country with a poor epidemiological policy and little data to track the incidence of certain diseases, including MNTI.
