Mucopolysaccharidosis: radiographic findings in a series of 16 cases.

OBJECTIVES To investigate the radiographic findings of mucopolysaccharidoses (MPS) on panoramic radiographs in a series of 16 patients. STUDY DESIGN This retrospective cross-sectional study included panoramic radiographs of 16 patients with cytogenetically diagnosed MPS. Two blinded, previously calibrated observers evaluate the presence or absence of the following features: type of dentition; stage of dental age in comparison with chronologic age; delayed exfoliation of deciduous teeth; supernumerary teeth; teeth impaction; enlarged, cyst-like dental crypt; hypercementosis; taurodontism; generalized enamel hypoplasia; enlargement of the bone marrow spaces; thinning of cortical bone; unusual morphology of condyles; and flattening of the condylar head. RESULTS The final sample was composed of 8 MPS IV, 7 MPS VI, and 1 MPS I cases. All patients presented unusual morphology of condyles. Cyst-like dental crypt (75%), taurodontism, and teeth impaction (68.75% each) were also overall common findings. Generalized enamel hypoplasia was exclusively identified in patients with MPS IV (75% of those patients). CONCLUSIONS Radiographic features of oral and maxillofacial manifestations in patients with MPS frequently encountered by dentists may help recognize the disorder. However, because of sample size limitations, it was not possible to infer any statistical relationship between the radiographic features and the types of MPS.

Epidemiological Profile of Facial Fractures and Their Relationship With Clinical-Epidemiological Variables.

AbstractThe objective of this study was to identify the epidemiological profile of facial fractures and to associate with clinical–epidemiological variables. An epidemiological survey was conducted in which data retrieved from the records of patients with facial fractures were analyzed. Pearson &khgr;2 test, Student t-test, one-way analysis of variance, Bonferroni post-hoc test, and logistic regression were used for statistical analysis, adopting a level of significance of 5%. The sample consisted of 718 patients ranging in age from 21 to 30 years (56.4%), including 480 (66.9%) men. Traffic accidents were the main etiological agent (62.7%) and the nasal bones were the most affected (41.8%). An association was observed between age and etiology (P < 0.001), fractured bone (P < 0.001), type of treatment (P < 0.001), hospital length of stay (P < 0.001), and complications (P = 0.001). Patients with traffic accident [odds ratio (OR) = 3.08, P < 0.001] and fall (OR = 2.50, P = 0.049) as etiology had more risk of complications. The type of fractured bone was associated with etiology (P < 0.001), type of treatment (P < 0.001), hospital length of stay (P < 0.001), and complications (maxilla—OR = 1.90, P = 0.004). In conclusion, facial fractures predominantly affect men aged 21 to 30 years. Traffic accidents are the main etiology and the nasal bone is the site most affected. It was observed that the older the patient, the greater the susceptibility to falls, surgical treatment, hospital stay, and complications. Patients with maxillary or mandibular fractures remain hospitalized for longer periods of time. Fractures by traffic accident and fall had more risk of complications. The risk of complications was also higher in patients with maxilla fracture.

Florid cemento-osseous dysplasia and peripheral giant cell granuloma in a patient with neurofibromatosis 1

We report a 35-year-old mulatto female patient with neurofibromatosis Type 1 who presented with facial asymmetry. The patient had two lesions: florid cemento-osseous dysplasia associated with peripheral giant cell granuloma. She was referred for surgical treatment of the peripheral giant cell granuloma and the florid cemento-osseous dysplasia was treated conservatively by a multidisciplinary team. So far, no changes have been observed in the patients clinical status. We observed no recurrence of peripheral giant cell granuloma. To the best of our knowledge, the present case is the first report of a patient with neurofibromatosis Type 1 associated with a giant cell lesion and florid cemento-osseous dysplasia.

Socioeconomic profile and academic performance of students on Campus VIII of the State University of Paraíba, Araruna, Brazil, 2013.

Aims: The aim of the present study was to analyze the socioeconomic profile and academic performance of students of three courses on Campus VIII of the State University of Paraiba. Study Design: A quantitative, descriptive, cross-sectional study with an inductive approach was carried out involving students in the courses of dentistry, civil engineering and natural science on Campus VIII of the State University of Paraiba (northeastern Brazil) in 2013. Methodology: A total of 321 students were enrolled, and the sample was made up of 238 participants who answered a semi-structured questionnaire addressing socioeconomic

Accuracy of Two Cephalometric Analyses in the Treatment of Patients with Skeletal Class III Malocclusion

The aim of the present study was to compare the treatment plan outlined from the diagnosis obtained by two different cephalometric analyses with the clinical decision made for surgical treatment of patients with skeletal Class III malocclusion. For this purpose, 82 skeletal Class III patients were evaluated, divided into three groups according to the surgical procedure performed for dentofacial deformity correction. Their preoperative cephalometric radiographs were submitted to McNamara and Steiner cephalometric analyses. The association of variables was evaluated by Kappa correlation (α=5%). The agreement between indication of surgical procedures performed based on clinical decision and surgical treatment indicated based on the evaluation of McNamara and Steiner cephalometric analyses were not significant (p=0.609 and p=0.544, respectively). McNamara and Steiner analyses showed reasonable agreement with each other as to the diagnosis, but did not agree with the clinical decision to treat skeletal CIII patients. Both tests were equally inaccurate in the indication of the surgical treatment.
