Intraoral tactile sensitivity in adults with diabetes.
Diabetes Care, 2004
rshinkai@pucrs.br OBJECTIVE: The intraoral tactile sensitivity (ITS) of diabetic and nondiabetic subjects was compared.
A total of 107 subjects (61.8 +/- 10.0 years; 48 women, 59 men) met American Diabetes Association diagnostic criteria for diabetes and 482 subjects (58.8 +/- 11.1 years; 274 women, 208 men) did not.
The dependent variable was the slope of the psychophysical function relating physical stimulus intensity (air pressure) and subjects' judgments of stimulus intensity.
Data were analyzed using ANOVA for repeated measures with between-subject factors of age, sex, ethnicity, and diabetes and the within-subject factor of intraoral site.
RESULTS: Diabetic and nondiabetic subjects showed no significant differences in ITS at any of the three test sites.
European Americans demonstrated greater soft-palate sensitivity (mean +/- SD 0.26 +/- 0.15) compared with Mexican Americans (0.24 +/- 0.16; P = 0.046).
The three intraoral test sites differed in tactile sensitivity (P < 0.001); posterior tongue (0.33 +/- 0.22) was most sensitive, followed by the soft palate (0.25 +/- 0.15) and the anterior tongue (0.23 +/- 0.13).
