NESI, Humberto; OLIVEIRA, Marcelo Tomás de    MOLINA, Gustavo Otoboni. Comparison of the use of membranes in conjunctive infiltration in alveoli freshly extracted teeth. Rev. Bras. Odontol. []. 2013, 70, 2, pp. 136-141. ISSN 1984-3747.

The aim of this study was to evaluate the behavior of new membrane comparing to others trademarks available in the market as for decrease conjunctive tissue infiltration in the rat's alveoli after extractions. 36 rats were randomly divided in four groups (control - GC, Teflon membrane (Gore-tex) -GT, polypropylene membrane (bone heal) - GP, Test membrane (cellulose impregnated doxycycline - GCD). Anova test showed no statistic difference between groups (p value = 0,0852). Despite no statistical difference all the membranes showed similar behavior and was possible noticed that have been reduced the depth of tissue infiltration.
