Gene expression analysis at 14 days after surgery. Comparative geneexpression analysis between drilling (Drill) and piezosurgey (Piezo) of 21genes involved with BMP signaling, Wnt signaling, inflammation, apoptosis andosteogenenis 14 days after surgery. * indicates statistically significantdifference (p < 0.05), Nd (not detectable) indicates lack ofdetectable expression (n = 5).
