ACCURACY OF CONE-BEAM COMPUTERIZED TOMOGRAPHY IN DETERMINING THE THICKNESS OF THE PALATAL MASTICATORY MUCOSA

BACKGROUND: The aim was to compare the thickness of the palatal masticatory mucosa as determined on a cone-beam computerized (CBCT) scan versus thickness determined via bone-sounding. METHODS: A total of twenty patients requiring palatal surgery participated. Thickness of the palatal tissue was measured at various points radiographically and clinically. The two techniques were compared to determine the agreement of the two measurement modalities. RESULTS: Analysis of variance determined that there was no significant difference between the two methods. A small bias of the radiographic measurement being larger was found to be statistically significant (0.09 ± 0.69mm; p <0.0001). Moreover, the tissue thickness was shown to increase as the distance from the gingival margin increased and the tissue over the molars was thinner than the tissue over the premolars. CONCLUSIONS: CBCT can be used to accurately determine the soft tissue thickness of the palatal masticatory mucosa with minimal bias.
