Six groups (n=10) 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 (10×2×1mm) and for compressive strength 9.5×5.5×3mm) and tested at 0.5 mm/min. Statistical analysis demonstrated the following for flexural strength (P< 0.05 ): I-sil: 155.89±45.27BC; P-sil: 155.89±45.27BC; I-sil/heat: 130.20±22.11C; P-sil/heat: 169.86±50.29AB; I: 131.87±15.86C. For compressive strength, the following are demonstrated: I-sil: 1367.25±188.77ab; P-sil: 867.61±102.76d; I-sil/heat: 1162.98±222.07c; P-sil/heat: 1499.35±339.06a; and I: 1245.78±211.16bc. 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.
