Drilling strategies for (a) serial and (b) bulk tooth samples.
Photos are taken with a reference ruler (cm) as a scale. (a) Serial samples of LACM HC 3805-L-12 are taken perpendicular to the growth axis and measure from the occlusal most point of the measured plate. (b) A bulk sample of ORR 11 is taken parallel to the growth axis.
