For each tooth position listed in the first column, the number of missing teeth in females (F), males (M) and their sum is reported, followed by the percentage. Percentages were analyzed with chi-squared test within each quadrant, significance below 0.001 is reported in the last column (Comparisons). Different letters mark different percentages within each quadrant, the same letter identifies percentages that are not significantly different.
