Estudo comparativo do desempenho de diferentes membranas oclusivas de Látex Natural no reparo ósseo

Introduction: In dentistry, alveolar bone resorption is a limiting factor in the well being of individuals directly interfering in the stomatognathic system, causing problems in the context of overall health. Aiming to promote biological methods that can stimulate bone regeneration, several biomimetic strategies have been developed by the use of diverse materials possible to the bone matrix, culminating in the development of techniques that promote such repair. Objective: This work is a comparative study of the performance of films made with latex as occlusive membrane for Guided Bone Regeneration (GBR) procedure in three preparations: Latex preserved in ammonia, produced by Latex rubber clones IAN873 and PR255 polymerized immediately after collection and without use ammonia as a preservative. Methods: Sixty Wistar rats were randomly divided into 4 groups of 15 animals in which bone defects of critical size (8mm diameter) were made surgically in the skull. Group A was treated by GBR through the membrane latex preserved with ammonia, Group B received the membrane made of latex from IAN873, Group C, the membrane clone PR255 and group D was not treated by GBR. After a period of 7, 15 and 50 days, 5 animals from each group were euthanized, and specimens containing bone defect collected for microscopic examination (descriptive histology and histomorphometry). Results: The results showed that after 50 days there was bone formation in higher proportions in group D (p <0.05, ANOVA followed by Tukey), suggesting that further experiments should be conducted to conclude about the presence of ammonia and the influence of kind of rubber. Conclusion: GOR is a procedure proven effective in the treatment of bone defects. Therefore, further experiments should be conducted to reach a conclusion regarding the presence of ammonia in the latex composition for the manufacture of membranes, as well as the difference induced by the species of rubber.

Eficácia de produtos químicos no controle do fungo manchador botryodiplodia theobromae em madeira de hevea brasiliensis

In Brazil, the exploration and use of the Hevea brasiliensis Mull Arg. wood at the end of the latex production cycle from 30 to 35 years, is practically unknown. However, one of the most significant problems with its use relates to the high susceptibility of this species wood to the fungus Botryodiplodia theobromae attack, especially during the primary wood processing phase. The present study evaluated the efficacy of four chemicals to control juvenile and adult Hevea brasiliensis wood from the attack of the fungus stainer Botryodiplodia theobromae following the ASTM 4445 (2003) standard. The results showed that the active ingredients separately tested and evaluated in the laboratory; (Quinolinolato Copper - 8 and Carbendazim (T1); Tribromofenol 2-4-6 (T2); Extract-Based Vegetable Tannin (T3); Carbendazim and Prochloraz (T4)) do not totally prevent the contamination of Botryodiplodia theobromae in 5% level of significance
