Introduction: Natural fibres such as kenaf fibres have enormous potential
in replacing synthetic fibre used for composite reinforcement.
Objectives: This study aimed to investigate the mechanical properties of rice
husk nano hybrid dental composite after addition of kenaf cellulose nano
crystals treated with silane hybridization.
Methodology: Kenaf cellulose nanocrystals (CNCs) were treated with
silane hybridization using tetraethyl orthosilicate (TEOS) sol gel and
γ-Methacryloxypropyltrimethoxysilane (γ-MPS) with different ratio of TEOS:
γ-MPS (0:1, 1:1, 1:2 and 1:3) which was later incorporated into composite resin
mixture. Six samples from each group were prepared for compressive and
flexural tests. Data was analysed using one-way ANOVA test.
Results: The means compressive and flexural strength of composite
reinforced with treated kenaf CNCs were increased compared to non-
reinforced composite even though the means strength were lower than the
commercial composite tested.
Conclusion: With further modifications, the addition of treated kenaf CNCs
via silane hybridization has potential to improve the mechanical strength of
rice husk nano hybrid dental composite.
