ABSTRACT Introduction: N-Butyl-cyanoacrylate is a tissue-synthesis material. It offers countless advantages: short application time, easy execution, as well as possessing hemostatic character. This material is bacteriostatic, biodegradable, and exhibits suitable tensile strength. Objective: The objective of the present paper was the histological evaluation of n-butyl-cyanoacrylate biocompatibility on rats dorsum (spine), compared to braided black silk and Polyglactin 910. Materials and Methods: Thirty six Wixtar albino rats were used for the procedure. They were randomly divided into four groups (A, B, C, D) related to the time of sacrifice (3rd, 7th, 14th and 21st day) respectively. On the rats' spine, three 2 cm long incisions were performed. Histological parameters were as follows: polymorphonuclear cell inflammatory infiltrate, young fibroblasts and epidermis thickening. Results: N-b...

Oralantral comunication is a surgical complication that manifests itself with the connection of the oral cavity and the maxillary sinus . Its etiology is related multiple factors. For its diagnosis and treatment it is necessary evaluate clinical caracteristics like the symtoms associated with the oralantral communication, onset and the size it manifests itself. If the oralantral comunication is not corrected , inflamatory and infectuos conditions can occur in the maxillary sinus .
