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 ofmethacrylate resin bars (BISGMA/TEGDMA, 50/50%). 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 × 3 mm) 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.
