Prevalence of carotid artery calcifications among 2,500 digital panoramic radiographs of an adult Brazilian population
2018
Background The aim of the present study was to analyze the epidemiological data of digital panoramic radiographs revealing suggestive images of carotid artery calcifications (CAC) from a Northeast Brazilian population. Material and Methods A cross-sectional retrospective study was conducted with 2,500 digital panoramic radiographs obtained from a single imaging reference center in Northeast Brazil. Images from individuals of both sexes and older than 18 years were included and those that did not cover the region of cervical vertebrae or presented low radiographic quality were excluded. Data were analyzed regarding prevalence, location (bilateral, right or left), sex, and age using the Chi-s…
Effect of different cryosurgical protocols using liquid nitrogen on bone tissue: a histomorphological analyze
2011
The aim of the present experimental study was to evaluate the morphological effects of different liquid nitrogen cryosurgery protocols on bone tissue. The femoral diaphyses of 42 Wistar rats were exposed to three local and sequential applications of liquid nitrogen for 1 or 2 min, intercalated with periods of 5 min of passive thawing. The animals were sacrificed after 1, 2, 4 and 12 weeks and the specimens obtained were processed and analyzed histomorphologically. Histologically, an increase in bone necrosis was observed for the two protocols in the second week after cryotherapy. A significant osteogenic phase was observed after 4 weeks. Moreover, complete remodeling process was encountered…
Gingival calcifying epithelial odontogenic tumor: case report and review of the literature comprising a period of 44 years
2011
Calcifying epithelial odontogenic tumors are rare odontogenic neoplasms that account for approximately 1% of all odontogenic tumors. The extraosseous variant is extremely rare, with only few cases being described in the literature. To our knowledge, only 22 cases have been reported over a period of 44 years. Therefore, the aim of this study was to present a critical literature review comprising the period from 1966 to 2010. In addition, we discuss the clinical presentation, diagnosis, and subsequent treatment of a patient with a gingival calcifying epithelial odontogenic tumor in the anterior mandible. This study shows that even though being an extremely rare neoplasm the gingival calcifyin…
Compositional and microhardness findings in tooth affected by X-linked hypophosphatemic rickets
2020
Background This study aimed to evaluate the X-linked hypophosphatemic rickets (XLHR)-related compositional and microhardness tooth aspects. Material and Methods One affected and one non-affected teeth by XLHR were sectioned transversely, and each section was separated for Micro-Raman spectroscopy, Knoop microhardness and scanning electron microscopy with energy dispersive x-ray microanalysis (SEM-EDS). The outcomes of these analyses were assessed. Results Outcomes of Raman analysis of inorganic/organic components (~958/~1250+~1450 cm−1) and carbonate/phosphate (~1070/~958 cm−1) ratios showed areas of altered enamel and dentin (interglobular dentin, calcospherites, and mantle dentin) with an…
Dental status, salivary flow, and sociodemographic aspects in Sheehan Syndrome patients
2018
Background Sheehan’s syndrome (SS) is one of the leading causes of hypopituitarism in developing countries. It occurs after postpartum necrosis of the pituitary gland, and it is considered a significant public health problem. This paper, apparently unpublished, aimed to perform an analysis on oral aspects in patients with SS. Material and Methods A cross-sectional study was performed with 23 women diagnosed with SS at the Division of Endocrinology and Diabetes (Walter Cantídio University Hospital, Fortaleza, Brazil). Results Data on sociodemographic, dental and salivary flow aspects were collected through a clinical approach and a panoramic radiograph request. The mean age was 64 ± 11.5 yea…
Oral granular cell tumor: a study of twelve cases in a Brazilian population
2010
Objectives: Analyze clinic and epidemiological aspects of all Oral Granular cell tumor (GCT) during a 5-year period in a Brazilian population. Study design: clinical and treatment outcome data of patients with oral GCT seen at the Division of Stomatology, School of Dentistry, Federal University of Ceara, Brazil, between January 2001 and December 2005 were reviewed. Results: during the analyzed period, 6231 oral lesions were collected from files of different anatomo-pathology laboratories situated in the state of Ceara, Brazil. Of all cases, only 12 of GCT were diagnosed. The lesion was more common in female patients, with a mean age of 40.8 years, occurring mainly in tongue. Conclusion: Ora…
Maxillofacial and dental-related injuries from a Brazilian forensic science institute : victims and perpetrators characteristics and associated risk …
2020
Background Trauma due to external causes represents one of the greatest challenges for public health services in different regions around the world. This study aimed to determine the prevalence of facial trauma, associated risk factors, and classification of body injuries in individuals who underwent forensic examination in a Brazilian center. Material and Methods Data were collected at the Ceará State Forensic Medicine unit in a 12-year period. Sociodemographic data related to the etiological agent and lesions resulting from the bodily injury were recorded. Results Among 1,031 physical injury exams, physical aggression (p<0.001), male victims aged between 21 and 30 years (p<0.001), salarie…
Sensitive nerve function measurement in facial trauma : an observational study
2020
Background Facial trauma is responsible for various types of health damage and may be functional or aesthetic. Depending on the degree of energy released in this type of trauma, sometimes an irreversibility degree is obtained. This study aimed to perform an objective evaluation of traumatic peripheral nerve injuries resulting from mandibular fractures and midface, using silicon monofilaments. Material and Methods This was an observational, cross-sectional study. All patients with maxillofacial fractures, who were hospitalized by the department of Oral and Maxillofacial Surgery of Instituto Dr. José Frota Hospital, were randomly recruited and screened for inclusion in the present study.
