Effect of tooth isolation on laser Doppler readings

The mean PBF with regular blood flow conditions was significantly different between single tooth isolation [5.53 PU (SD±2.98)] and multiple tooth isolation [2.85 PU (SD±2.13)] (P<0.01). When local anesthesia was administered (LI), the PBF was significantly different between single tooth isolation [2.95 PU (SD±2.48)] and multiple tooth isolation [1.32 PU (SD±0.70)] (P <0.05). Significant differences in PBF also existed between single tooth isolation under regular blood flow conditions and with local anesthesia (P <0.01), between single tooth isolation under regular blood flow conditions and multiple tooth isolation with local anesthesia (P <0.01), and between multiple tooth isolation under regular blood flow conditions and with local anesthesia (P <0.05).
