Molhabilidade de material reembasador: efeito dos agentes químicos de limpeza

Risk of mechanical injuries contraindicate brushing and elect chemical agents as appropriate for daily cleaning of dentures relined with resilient materials. It was evaluated the effect of denture cleansers on the wettability of denture relining material (Dentusoft, Dental Medrano). We used 20 discs of acrylic resin thermoactivated VipiCril ® with 30mm diameter and 4mm thick, covered by 2mm Dentusoft ®. Divided into 4grupos were stored in artificial saliva at 37 +1 º C for 30 days, immersed daily for 15minutes in distilled water (GI), Corega ® Tabs (GII), a solution of sodium bicarbonate (GIII) or solution of sodium hypochlorite (GIV) after which, on the soft liner were poured 2 ml of type IV gypsum (Durone IV, Dentsply). Reached the final setting of the gypsum specimens were sectioned vertically and medially, settled water with sandpaper No. 400 and mounted on suitable device for reading (in the right and left) of the contact angle Carl Zeiss microscope (precision, 001). The results were submitted to analysis, showed non-normal distribution, opting for non-parametric test. Kruskal Wallis test performed at 5% significance, there was statistical difference between the groups with lower average contact angle for GII. It was concluded that the chemical cleaning Corega Tabs ® allowed a better adaptation of relining the gypsum studied.

Efeito do ácido tranexâmico associado à cola de fibrina sobre o reparo ósseo: estudo histológico em ratos

The bone repair process is controlled by complex molecular mechanisms that involve systemic and local factors. Fibrin glue is derived from human plasma and mimics the final pathway of coagulation network. Tranexamic acid inhibits fibrinolysis and prevents or decreases the formation of degradation products of fibrin and fibrinogen. The purpose of this study was to evaluate histologically in rats the effect of tranexamic acid associated with the fibrin glue on bone healing. The experiment used 60 (n = 5) male rats in: GI: Control, GII: fibrin glue, GIII tranexamic acid and GIV /fibrin glue/tranexamic acid. Bone defect (2.5mm diameter) was created in right tibia. The animals were euthanized at 7,14 and 30 days postoperatively, and the pieces were processed with hematoxylin and eosin. The results showed at 7 days post-operative surgical cavity filled with dense connective tissue rich in fibroblasts, permeated by delicate neoformed bone trabeculae in percentage of 70-80% for GI, GII and GIII and GIV to 94.8%. At 14 days post-operative newly formed bone was found between 75-85% for GI, GII and GIII and percentage above 95% for GIV. At 30 days postoperative GI and GIV showed 95-100% of mature bone tissue; GII and GIII in percentage close to 80-90%. Based on the results and methodology is concluded that fibrin / tranexamic acid glue association has positive action on bone repair.

Relação entre a presença da equipe de saúde bucal na estratégia saúde da família com o nível de conhecimento dos agentes comunitários de saúde

Objective: to identify the relation between the level of knowledge of community health workers on oral health and the presence of the Oral Health Team in the Family Health Strategy. Methods: we performed a survey with 173 community health workers allocated in public health services of five municipalities in the northwest of São Paulo, Brazil, through a self-administered and structured instrument. The survey instrument contemplated questions related to the presence of the Oral Health Team in the Family Health Strategy and questions regarding oral health. Results: the majority of community health workers was inserted in strategies with the presence of Oral Health Teams (60.1%). We found that the oral health knowledge of most participants was good (48%). Conclusion: there is relation between the level of knowledge of community health workers and the presence of the Oral Health Team in the Family Health Strategy.

Ética e atuação profissional: percepção de agentes comunitários de saúde

The perceptions of the Community Health Agent (CHA) referred to ethics in their work have been evaluated in this study. A questionnaire with social and ethical issues was applied in 61 ACS. 90% reported having received information about ethics, and “training courses” was the most cited source (68.9%). On a scale from 1 (least) to 5 (maximum), 67% claimed to have knowledge about ethics among 4 or 5 and 88.5% reported that this topic has an importance of 5 in their work. Ethical conflicts exposed had an average of 75% of respondents in agreement with the reference sources, and the two items involving “information privacy” showed the greatest disagreement. Ethics was considered important by the professional performance of subjects who had a good perception about the issue; however the topic about privacy of information generated controversy.

Chronic osteomyelitis of the maxilla and mandible: microbiological and clinical aspects

Osteomyelitis of the mandible and maxilla are common in developing countries and their treatment may be long-standing and difficult. Thus, the aim of this study was to discuss the main biological aspects of the chronic osteomyelitis of the jaws of especial interest for dental team. These infections are associated with a complex microbiota composed mainly by anaerobic bacteria, sometimes associated with microorganisms originated from the skin and digestive tract. These data suggest that chronic osteomyelitis of the mandible and maxilla should be treated as anaerobic infections in most cases. In addition, local surgical treatments are relevant in the therapy outcome, associated to the use of antimicrobial agents, and the failure to accomplish them is a major cause of treatment failure.
