Table 2. Noise values of each region as a function of the spatial orientation of the head, dental implant condition, metal artifact reduction (MAR) activation, and tube current (mA).

^*: P<0.05 compared to “standard orientation,” ^†: P<0.05 compared to “without dental implant,” ^‡: P<0.05 compared to “without MAR.” Different letters indicate a significant difference between tube current levels within the same conditions of orientation, dental implant, and MAR (P<0.05)
