ABSTRACT
Background/purpose:
Amoxicillin and clindamycin are the most effective decontaminants for intraoral bone grafts before their application in bone regeneration without cytotoxic effects on osteoblasts, but their effects on the gene expression of markers involved in osteoblast growth and differentiation remain unclear. The study objective was to determine the effects of amoxicillin and clindamycin on the gene expression of markers involved in osteoblast growth and differentiation. Materials andmethods:
Real-time polymerase chain reaction (RT-PCR) was performed to explore the effect of 150 µg/mL clindamycin or 400 µg/mL amoxicillin on the gene expression by primary human osteoblasts (HOBs) of runt-related transcription factor 2 (Runx-2), osterix (OSX), alkaline phosphatase (ALP), osteocalcin (OSC), osteoprotegerin (OPG), receptor activator for nuclear factor κ B ligand (RANKL), type I collagen (Col-I), bone morphogenetic proteins 2 and 7 (BMP-2 and BMP-7), TGF-ß1 and TGF-ß receptors (TGF-ßR1, TGF-ßR2, and TGF-ßR3), and vascular endothelial growth factor (VEGF).Results:
Treatment with 150 µg/mL clindamycin significantly increased the gene expression of TFG-ß1, TGF-ßR1, TGF-ßR2, TGF-ßR3, RUNX-2, Col-1, OSX, OSC, BMP-2, BMP-7, ALP, VEGF, and RANKL by HOBs. Treatment with 400 µg/mL amoxicillin significantly increased the gene expression of TGF-ß R1, Col-I, OSC, RANKL, and OPG alone.Conclusion:
These findings suggest that 150 µg/mL clindamycin is the decontaminant of choice to treat intraoral bone grafts before their application in bone regeneration. The osteogenic and antibacterial properties of clindamycin can favor and accelerate the integration of bone grafts in the oral cavity.
