Abstract
Titanium and its alloys are commonly used in dentistry for implants due to their strength, lightweight nature, durability, corrosion resistance, and biocompatibility. These implants can osseointegrate after surface treatments such as SLA, plasma-spray, and nanotubes, providing a stable foundation for prostheses. However, Candida albicans, an opportunistic fungal pathogen, can threaten the success of titanium dental implants, causing oral infections in vulnerable individuals. A dual novel silane blend of 3-acryloxypropyltrimethoxysilane (ACPS) and bis-1,2-(triethoxysilyl)ethane (BTSE) has been shown to improve the shear bond strength in resin cement bonds with titanium and ceramics. This study evaluated the effects of Candida albicans colonization on blended silane-coated SLA-Ti surfaces compared to non-coated SLA-Ti (positive control) and flat titanium (negative control). Candida albicans biofilms were cultured on all surfaces, and it was found that silane-coated SLA-Ti had significantly lower CFU counts than non-coated SLA-Ti. However, no significant differences were observed in the RT-PCR results. In conclusion, a combination of 1.0 vol% ACPS and 0.3 vol% BTSE shows promise as a silane coupling agent with potential antifungal properties for inhibiting Candida albicans proliferation.
