Desenvolvido pela Universidade Estadual de Ponta Grossa (UEPG), em parceria com a Secretaria Municipal de Saúde e o Ministério da Saúde, o Programa de Reorientação da Formação Profissional em Saúde (PRÓ/Saúde), associado ao Programa de Educação pelo Trabalho para a Saúde (PET-Saúde), tem oportunizado a realização de estágios-vivência em equipes multiprofissionais, com a iniciativa de consolidar a integração ensino-serviço-comunidade. Em relação à Odontologia, os acadêmicos petianos têm tido a oportunidade de conviver com colegas de outros cursos de graduação e de vislumbrar a integralidade do cuidado e demais princípios do SUS na prática. Uma das atividades dos grupos PET-Saúde são as visitas domiciliares na comunidade assistida pela Estratégia Saúde da Família (ESF) local. Tais visitas têm propiciado o exercício das competências preconizadas    pelas    Diretrizes    Curriculares Nacionais para os acadêmicos de odontologia. Este trabalho apresenta a vivência dos acadêmicos nas visitas domiciliares e relata como dois casos clínicos singulares permitiram aos  acadêmicos  envolvidos o exercício do perfil generalista e humanista e a capacitação de atuar multiprofissionalmente. Reconhecendo a realidade social dos pacientes, buscou-se explicar a importância do tratamento e os procedimentos que seriam realizados, obtendo-se sucesso nas intervenções. As visitas domiciliares como uma das estratégias de trabalho do PRO/PET-Saúde na UEPG permitiram a convivência com situações socioeconômicas distintas, o entendimento do contexto social vivido pelas famílias e a aplicação prática do conhecimento teórico adquirido no curso. Os programas PRO/PET-Saúde na UEPG têm se mostrado como importantes ferramentas para o desenvolvimento de competências e habilidades e estímulo para a inserção futura dos egressos no Sistema Único de Saúde.

The limited options for bone repair have led to an extensive research of the field and the development of alloplastic and xenogeneic grafts. The purpose of this study was to evaluate bone repair with two bone substitutes: deproteinized bovine bone (DBB) and biphasic calcium phosphate ceramic (BCP) in critical-size defect. A total of 8-mm defects were made in the parietal bones of rabbits (n=12). The animals were divided into three experimental groups: sham (defect filled with a blood clot), DBB (defect filled with DBB), and BCP (defect filled with BCP). After the experimental periods of 15 and 45 days, the animals were euthanized and submitted to histomorphometric analysis. The total defect area, mineralized tissue area, biomaterial area, and soft tissue area were evaluated. A greater amount of immature bone tissue and biomaterial particles were observed in the BCP group compared to DBB and sham at 45 days (p<0.05). There was no difference in the qualitative pattern of bone deposition between DBB and BCP. However, the sham group did not show osteoid islands along with the defect, presenting a greater amount of collagen fibers as well in relation to the DBB and BCP groups. There was a greater number of inflammatory cells in the DBB at 45 days compared to BCP and sham groups. In conclusion, BCP and DBB are options for optimizing the use of bone grafts for maxillofacial rehabilitation. Bone defects treated with BCP showed greater deposition of bone tissue at 45 days.

Background Several drugs are capable of promoting changes in bone metabolism. The aim of this study was to evaluate the effect of long-term low-dose aspirin (LDA) therapy on implant osseointegration. Methods Male Wistar rats were divided into 4 groups (n = 8/group) according to oral gavage solution received prior (42 days) to the implant surgery on the tibia. The control group was treated with saline solution for 7 (CG-7) and 28 (CG-28) days. The use of low-dose aspirin was performed in AG groups (6.75 mg/kg of aspirin) for 7 (AG-7) and 28 (AG-28) days. After experimental periods, histomorphometric evaluation of bone-to-implant contact (BIC) and the bone area between threads (BABT) was performed. Results Reduced BIC values were detected in AG-7 (62.8% ± 17.1) group compared to AG-28 (91.9% ± 5.4), CG-7 (82.7% ± 15.2), and CG-28 (89.9% ± 9.7). BABT evaluation revealed lower values in AG-7 (70.9% ± 15.2) compared to AG-28 (95.4% ± 3.7) and CG-28 (87.1% ± 10.2) groups. Conclusions The treatment with low doses of aspirin promoted a discrete inhibitory effect in the early stages (7 days) of repair after implant placement, specifically in the bone deposition. However, these effects were not detected in the late stages (28 days), considering BIC and BABT parameters.

This case report showed an AOT in a 12-year-old female patient referred for orthodontic-surgical of both impacted right mandibular canine and lateral incisor. Cone beam computed tomography revealed a well-defined mixed hyperdense/hypodense lesion, involving the crown of the mandibular lateral incisor. The surgery consisted in surgical exposure of the mandibular right canine and lateral incisor, bonding of the lateral incisor for orthodontic traction and curettage of the mandibular lesion. Histopathological examination revealed several columnar epithelial cells with minimal stromal connective tissue, lobular pattern and rosettes and duct-like structures, confirming the diagnosis of AOT. After, the patient was referred for orthodontic traction of the impacted teeth. At 1 and 3-year postoperatively, follow-ups examinations showed extensive bone repair, resolution of the tooth-retention and absence of recurrence. Although AOT is an uncommon lesion in the mandible, it should be considered in the differential diagnosis of the mixed profile lesions in this region.
