Integração da disciplina Promoção da Saúde Bucal 3 com a Clínica da Família e o território adscrito na formação em Odontologia / Integration of the Oral Health Promotion 3 discipline to the Family Clinic and the Dentistry training-associated domain

O relato dessa experiência tem como pressuposto a reorientação das práticas e dos cenários de ensino e aprendizagemna disciplina Promoção da Saúde Bucal 3 do curso de graduação em Odontologia do Centro Universitário São José para uma abordagem contextualizada ao território, integrada à Clínica da Família,orientada à promoção da saúde bucal e às necessidades da população.Temcomo objetivo estimular que os estudantes sejam formados numa perspectiva crítico-reflexiva, compreendendo saúde como produção social e reconhecendo os impactos dos determinantes sociais da Saúde no processo do cuidado em saúde bucal. A integraçãodas aulas da disciplina à rotina de atividades desenvolvidas pela Clínica da FamíliaArmando Palhares Aguinaga, na área programática 5.1, possibilitou uma troca de saberes e vivências entre alunos, pacientes (vistos como sujeitos), professora, agentes comunitários de saúde e profissionais da clínica, aproximando o processo de ensino das dinâmicas sociais e das necessidades do território (AU).

The report on the present experience is based on reorienting teaching and learning practices and scenarios in the discipline of Oral Health Promotion 3 of the undergraduate Dentistry course ofthe Centro Universitário São José (São José University Center), aimed at a contextualized approach to the domain, integrated to Family Clinic, and oriented toward oral health promotion and to the needs of the population. It aimed to encourage student trainees toward a critical-thinking perspective, encompassing health as social production, and acknowledging the impacts of the Social Determinants of Health on the oral health care process.By integrating the discipline into the routine of the activities developed by the Clínica da FamíliaArmando Palhares Aguinaga (Armando Palhares Aguinaga Family Clinic)in the 5.1 program, Dentistry training has enabled exchange of knowledge and experiences among students, patients (seen as subjects), teacher, outreach health workers, and professionals of the clinic, bringing the process of teachingsocial dynamics and the needs of the domain closer together (AU).

Caprine demineralized bone matrix (DBMc) in the repair of non-critical bone defects in rabbit tibias. A new bone xenograft.

PURPOSE: To evaluate the use of demineralized bone matrix of caprine origin in experimental bone defects of the tibia in New Zealand rabbits. METHODS: Fragments of the tibia diaphysis were collected aseptically from clinically healthy goats. The bones were sectioned into 1 cm fragments and stored at -20°C for subsequent hydrochloric acid (HCL) demineralization. A 70 mg portion of DBMc was used to fill the experimental bone defects. Twenty-four female adult New Zealand rabbits were divided into 2 groups: the MG (matrix group, left tibia) and CG (control group, right tibia). Additionally, they were separated into 4 groups with 6 animals, according to the period of analysis (15, 30, 60 and 90 days postoperatively). Using microCT, volumetric parameters were evaluated: bone volume, relationship between bone volume and total volume, bone surface area, relationship between bone surface area and total volume, number of trabeculae, trabecular thickness and trabecular separation. RESULTS: There was a statistically significant difference (P<0.05) between groups considering bone volume (BV) and bone:total volume (BV/TV), on 15, 30 and 90 days postoperatively. Control group showed a statistically significant superiority (P < 0.05) considering the mean of the variables bone surface (BS), number of trabeculae (Tb.N) and between bone surface and total volume (BS/TV) at 15 and 90 days. CONCLUSIONS: Caprine demineralized bone matrix was safe and tolerable. No signs of material rejection were seen macroscopically. It is an alternative for the treatment of bone defects when autologous graft is not available or in insufficient quantities.
