Methods and materials
The study was performed in two parts.
In the first part the measurements were done on an intraoral dental x-ray unit.
The dose area product (DAP) was measured using an external DAP meter that was placed directly under the position indicating device (PID).
Measurements were performed according to exposure parameters that are used daily in the clinical environment for each separate image.
The exposure parameters used were 60 kVp and 7 mA with different exposure times for separate imaging part which are described in the table 1.
In the second part the DAP values for 180 adult patients that were referred to panoramic imaging were collated.
Shapiro Wilk test was used to determine the normal distribution of the variable and One-Sample Wilcoxon Signed Rank Test was used to determine the dose differences between panoramic and full mouth series.
