Mean SSPT width was 4 mm (range 2.5-6) in G1,
3.7 mm (range 2-5) in G2 and 3.7 mm (range 2.5-5.5) in G3.
Mean SSPT length was 43.4 mm (range 32.5-55.5) in G1,
44.3 mm (range 36-58.5) in G2 and 46.7mm (range 37-57.5) in G3.
Mean SSCT width was 3.7 mm (range 3-5) in G1, 3.7 mm (range 2-5) in G2 and 3.8 mm (range 2.5-5) in G3.
Mean SSCT length was 49 mm (range 38.5-61) in G1,
49.1 mm (range 40-59) in G2 and 54.1 mm (range 46-66.5) in G3.
Mean ISPT width was 3.5 mm (range 2.5-6) in G1,
3.5 mm (range 2-5) in G2 and 3.7 mm (range 2.5-5) in G3.
Mean ISPT length was 50.2 mm (range 26-62.5) in G1,
48.3 mm (range 39-61) in G2 and 52 mm (range 39.5-68.5) in G3.
There was a statistically significant difference between the different age groups in terms of SSP thickness (P=0.02) and length (P<0.0001); ISP thickness (P=0.04) and length (P=0.003); and SSC length (P<0.0001).
No significant difference between the groups was found in terms of SSC thickness (P>0.05).
No significant difference was found between the measures obtained by the first and the second operator.
