This study evaluated the influence of silane heat treatment and glass fiber fabrication type, industrially treated (I) or pure (P), on flexural and compressive strength of methacrylate resin bars (BISGMA/TEGDMA, 50/50%). Six groups were created: I-sil: I/silanated; P-sil: P-silanated; I-sil/heat: I/silanated heated to 100°; P-sil/heat: P/silanated heated to 100°; (I: I/not silanated; and P: P/not silanated. Specimens were prepared for flexural strength and for compressive strength ) and tested at 0.5 mm/min. Statistical analysis demonstrated the following for flexural strength : I-sil: ; P-sil: ; I-sil/heat: ; P-sil/heat: ; I: . For compressive strength, the following are demonstrated: I-sil: ; P-sil: ; I-sil/heat: ; P-sil/heat: ; and I: . Due to the impossibility of incorporating the stipulated amount of fiber, P group was excluded. Glass fiber treatment with heated silane enhanced flexural and compressive strength of a reinforced dental methacrylate.
