Fig. 3. Distribution of mass size (mm), stratified by sex, of complex and compound odontomas, where the masses were determined from panoramic radiographs. Data are illustrated by density line (A) and boxplot (B), in which the horizontal line and the black square (▮) correspond to the median and mean values, respectively. P-values are derived from the bootstrap method using median values (*) or the t-test (†) for 2-sample comparisons. CpOD: compound odontoma; CxOD: complex odontoma.
