Table 2.

The mean and standard deviation of the intra-oral surface area (in cm²) for the cadavers, stratified according to gender

Surface area in cm2	Total (N = 20)	Female (N = 8)	Male (N = 5)	P-value difference female vs male	ICC
Palate	20.0 ± 2.88	20.0 ± 1.78	19.4 ± 4.05	0.748	0.77
Tongue	35.2 ± 5.16	35.0 ± 3.26	34.0 ± 3.67	0.633	0.90
Hard tissue	21.5 ± 11.06	26.4 ± 10.32	15.6 ± 9.76	0.087	0.95
Mucosa	96.6 ± 12.10	94.8 ± 14.55	96.9 ± 12.6	0.792	0.95
Total area	173.3 ± 19.3	176.1 ± 18.6	165.9 ± 18.2	0.353	0.99

N indicates the number of cadavers. The P-value of the ANOVA one-way test is shown. The ICC indicates the degree of agreements between the different researchers for the oral surface areas. For 7 cadavers the gender was unknown, for this reason they are not included in the ANOVA comparison
