Surgical excision of polymorphous adenocarcinoma in the left maxilla with mucocutaneous flap reconstruction
ABSTRACT Low-grade polymorphous adenocarcinoma is a malignant neoplasm of salivary glands with uncommon occurrence in the head and neck region, almost exclusively affecting minor salivary glands. While this condition has typical clinical pathological signs, it commonly presents low biological damage potential. The lesions occur more frequently among elderly females between the sixth and eighth decades of life, with a higher prevalence for the hard palate, soft palate and, most regularly, the upper lip and jugal mucosa. The clinical and histological differential diagnosis of this condition is between pleomorphic adenoma and...

Alveolodental ankylosis: biological bases and diagnostic criteria
ABSTRACT Alveolodental ankylosis is the fusion of cementum or root dentin with the alveolar bone in both deciduous and permanent teeth. This leads to important clinical and radiographic changes in the affected teeth. Moreover, knowledge of the biological principles involved allows adequate management of teeth affected by this phenomenon.RESUMO A anquilose alveolodent ária consiste na fusão do cemento ou dentina radicular com o osso alveolar tanto em dentes decíduos como nos dentes permanentes. Isto leva a uma série de alterações clínicas e radiográficas importantes para o diagnóstico. Além disso, o conhecimento d...

Microcephaly caused by the Zika virus: dental care
ABSTRACT Zika virus infection was declared a public health emergency at national and international levels due to the high incidence of the virus infection and its relationship with the birth of children with microcephaly. Patients with microcephaly present significant clinical neuropsychomotor disorders, therefore, dental surgeons should be prepared to treat such patients, observing the possible alterations associated with this condition, as well as the oral diseases. Thus, the purpose of this research study was to inform dental surgeons about the microcephaly associated with the Zika virus, as well as instructing them abo...

Sexual dimorphism of mandibular measures from computed tomographies
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.RESUMO Objetivo: Analisar medidas mandibulares obtidas de 225 tomografias computadorizadas do “ Biobanco Osteol ógico e Tomográfico da Faculdade de Odontologia de Piracicaba Universidade Estadual de Campinas ” , visando verificar a exist ência de relação entre essas medidas, o dimorfismo sexual e a ancestralidade. Métodos: Buscou-se estabelecer um modelo matemático capaz de ...

Spatial distribution of decayed and restored teeth in an adult population
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.RESUMO Objetivo: Analisar a distribui ção espacial dos dentes cariados e restaurados em adultos segundo o Índice de Exclusão Social (IEX) e a proximidade de serviço odontológico público.

Buccal bifurcation cyst as an incidental finding in cone beam computed tomography scans
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 clo...

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