title: Evaluation measure of 3d volumetry of masseter hypertrophy: association with modalities of imaging

description: Abstract Masseteric hypertrophy is a benign condition, asymptomatic and rare, characterized by the excessive development of the masseter muscle, which usually results in aesthetic complaints. The imaging exams for differential diagnosis of pathologies in the parotid-masseteric region is always recommended. This work aims the imaging characterization of masseteric hypertrophy through the report of two clinical cases combining different imaging modalities: panoramic radiography, magnetic resonance imaging, computed tomography, ultrasonography and 3D volumetry. Two male subjects with no family history of masseteric hypertrophy were referred to a diagnostic center in dentomaxillofacial radiology due to an increase in bilateral facial volume in the masseteric region. Images of the panoramic radiography showed an increase of the bilateral mandibular angle in both cases. Using computerized tomography, bilateral masseter muscle hypertrophy was demonstrated in the patients, and magnetic resonance scan and ultrasound examination were performed for better visualization and muscle measurement. 3D volumetry assessment of musculature showed as additional tool to evaluate the status of the masseter muscles in patients with Masseteric hypertrophy. Therefore, the association of imaging examinations allowed to perform the imaging characterization of masseteric hypertrophy with presence of bone exostosis.

title: Buccal bifurcation cyst as an incidental finding in cone beam computed tomography scans

description: ABSTRACT Buccal bifurcation cyst is an unusual inflammatory odontogenic cyst of unknown etiology which occurs at the buccal region of the permanent mandibular first molars in children and adolescents aged 6-15 years old. The aim of this manuscript is to present two clinical cases of buccal bifurcation cyst incidentally detected in adolescents referred for tomographic exams (CBCT) as part of the treatment planning for the management of impacted mandibular molars. The first case is very interesting due to the proximity of the lesion to the inferior alveolar canal. In the second case the inferior alveolar canal was not in close proximity to the lesion, but in contact with the mesiobuccal root of the second molar. The diagnosis of Buccal bifurcation cyst is of utmost importance in order to avoid complications during surgical procedures. In addition, the present case reports have highlighted the importance for dental practitioners to be aware of the possibility of a buccal bifurcation cyst being present as an incidental finding in CBCT images, especially in young patients.

title: Pediatric patient with diagnosis of extra osseous Ewing’s sarcoma of the tongue: case report

description: ABSTRACT Ewing’s sarcoma is a malignant tumor that arises mainly from bone tissue, so that its extra-osseous presentation is not very common and even more unusual, in the soft tissues of the oral cavity. The objective of this case was to describe the clinical characteristics of an extra-osseous Ewing’s Sarcoma of the tongue in a pediatric patient. An 11-year-old male school patient, who attended an oral medicine consultation referring a volume increase in the tongue. Intraorally, a tumoral lesion was observed on the left lateral edge of the tongue, indurated, with the same color of the mucosa with ulcerated areas, well defined edges and symptomatic on palpation, with an approximate size of 2.5 cm. A cervical and maxillofacial MRI was indicated, observing a partially delimited hyperintense and non-infiltrating lesion in the described area. An incisional biopsy was performed with histopathological diagnosis of malignant neoplasm of blue round cells, theCD99 marker was found to be positive in the immunohistochemical study and was key to the definitive diagnosis of this tumor. A thoraco-abdomino-pelvic tomography was requested by the Pediatric Oncology service, as well as biopsy and aspiration of bone marrow, in which no neoplastic infiltrations were evidenced. After four cycles of chemotherapy, total removal of the lesion was performed with a consecutive histopathological study of the surgical piece, indicating free edges of the lesion. Ewing’s sarcoma is a tumor with aggressive behavior, so this case represents a finding of clinical and epidemiological relevance, both due to its extra-osseous appearance and its unusual behavior.

title: Restorations with Bulk Fill restorative system: case report

description: ABSTRACT Bulk Fill Composite resins are restorative materials that present low tension and polymerization shrinkage, allowing them to be inserted in a single increment of up to 4 mm of thickness, in a restorative cavity. This paper aims to report a clinical case of restorations done on posterior teeth with Bulk Fill restorative system, using selective acid-etching with self-etch adhesive system. Patient, male, 24 years old, presented a carious lesion on the occlusal surface of dental element 37 and an occlusal unsatisfactory amalgam restoration, on element 36. A restorative treatment with Universal Bond 3M / ESPE and bulk fill composite resin (3M / ESPE) was done. According to the case described, it was possible to observe that the materials and techniques used restored the form and function of the teeth involved, preserving pulp vitality with a satisfactory aesthetic result. The bulk fill resins employed offer practicality and decrease clinical time, with satisfactory clinical applicability in the aesthetic and functional rehabilitation of posterior teeth.

title: Periodontal condition of adolescents and associated factors

description: ABSTRACT Objective: This study aimed to describe the periodontal condition of adolescents and identify its potential determinants. Methods: This is a cross-sectional population-based study (n=763) conducted in a city in Northern Minas Gerais. Multistage probability cluster sampling method was used. Trained and calibrated professionals carried out the intraoral examinations and the interviews at the participants’ homes. Logistic regression model was used to identify the factors associated with the periodontal condition. Results: It was found that around 30% of the adolescents presented periodontal changes, being gingival bleeding (14.1%) and dental calculus (14.0%) the most prevalent impairments. Periodontal changes were associated in adolescents who did not attend school (OR=1,9; p=0.031), attended public schools (OR=2,0; p=0.005), never went to the dentist (OR=1,7; p=0,047), used public/philanthropic services (OR=1,7; p=0,002), smoked (OR=1,6; p=0,003), consumed alcohol (OR=1,6; p=0,016) and self-perceived their oral health as too bad/bad (OR=2,4; p=0,032) and regular (OR=1,5; p=0,023). Conclusion: About one-third of adolescents have periodontal changes, which were associated with the type of school and type of dental service they attend, smoking, alcohol consumption and self-perception of oral health.

title: Sexual dimorphism of mandibular measures from computed tomographies

description: ABSTRACT Objetive: The objective of this study was to analyze mandibular measurements obtained from 225 computed tomography scans of the Osteological and CT Biobanks of Faculdade de Odontologia de Piracicaba Universidade Estadual de Campinas, aiming to verify the existence of a relationship between these measures and sexual dimorphism and ancestry. Methods: We sought to establish a mathematical model capable of estimating sex and ancestry. Of these scans, 126 were male, 94 were female and 5 were unidentified, aged 15 to 100 years, and ancestry known for the skin color phenotype (white, black, brown and yellow). Measurements were made between the following points: right lateral condylion and left lateral condylion; right lateral condylion and pogonion; left lateral condylion and pogonion; mesial border of right mental foramen and mesial border of left mental foramen. The area delimited by the triangle formed by the measurements between right lateral condylion and left lateral condylion was also analyzed; right lateral condylion and pogonion; and left lateral condylion and pogonion. Student t test for homogeneous variances showed that there was statistical difference in the means as a function of sex, except for the area measure, which was not used in the model. Results: It was possible to establish a mathematical model with accuracy of 69.2%. There was no statistical difference in the averages as a function of ancestry. Conclusion: It is concluded that the measures investigated help in the process of estimating sex, but were not adequate to estimate ancestry. The proposed methodology should be expanded to other population groups so that it can be improved.

title: Spatial distribution of decayed and restored teeth in an adult population

description: ABSTRACT Objective To analyze the spatial distribution of decayed and restored teeth in adults according to the Social Exclusion Index (SEI) and the proximity of public dental service. Methods: This ecological study used secondary data from an epidemiological survey of oral health and from the Piracicaba Research and Planning Institute (IPPLAP). The oral examinations of the DMFT index examined in households by a single examiner calibrated in 2011, by probability sampling, 248 adults (aged 20 to 64 years) representing the residents in Piracicaba-SP, Brazil. Data on social exclusion and health units with dental service were extracted from IPPLAP. We performed georeferencing of the census tracts selected by draw in the epidemiological survey and their respective districts, in addition to the health units with dental service in a radius of 500 m and 1000 m. Spearman’s rank correlation coefficient was analyzed (p&lt;0.05). Results: The smallest value of SEI, that is, the highest social exclusion, showed no correlation with decayed teeth (p=0.09), but had strong positive correlation with restored teeth (r=0.79; p&lt;0.0001). Presence of public dental service in the vicinity of 500 m and 1,000 m showed no correlation, respectively, with the average number of decayed (p=0.07 and p=0.58) and restored (p=0.26 and p=0.56) teeth. Conclusion: Although the correlation between social exclusion and caries in adults was not observed, its case management, namely, the restored teeth, showed correlation with social inequalities. Presence of public dental service showed no correlation with components of caries experience evaluated in this study.

title: Parents’ knowledge about the oral health care of oncological children

description: ABSTRACT Objective: identifying the parents/guardians’ knowledge about the oral health condition of oncological children assisted at the Pediatric Oncology Department of the Institute of Integral Medicine Professor Fernando Figueira. Methods: A cross-sectional study comprising a sample of 163 parents/guardians of children assisted at the Pediatric Oncology Department of the IIMP in the city of Recife, Pernambuco, applying a semi-structured form, tested with 10% of the sample in a pilot study. Results: Most of the parents/guardians were female subjects (87%) and patients’ mothers (81%), between 25 and 34 years of age (44.8%), with a family income of a minimum wage (47%), educational level until elementary school (51.6%) and from the countryside of the state of Pernambuco (56%). Most of the children were male subjects (58.9%) with average age of 7.57 years, who had attended or stopped primary school (54.6%) and had been diagnosed with Acute Lymphoblastic Leukemia (57.7%) and treated with chemotherapy (92.6%). All parents considered important to have dental surgeons in the oncology department assisting the children in their oral hygiene. More than half of these parents reported knowing about how to avoid caries (63%) and, almost half of the children had never had a consultation with a dentist before (41.1%). Conclusion: Parents/guardians have information about oral health care, but they do not put it into practice.
