Taste evaluation in adolescents and pediatric patients with benign migratory glossitis.

OBJECTIVE

Benign migratory glossitis (BMG) is a disease that affects the tongue and is considered an inflammatory disorder well recognized. It is characterized by the appearance of erosive areas on the dorsum and lateral border of the tongue that can be isolated or multiple. The aim of this study was to assess whether the perception of taste to the four basic tastes is altered due to the presence of BMG.

METHODS

Forty individuals of both sexes with a mean age of 12.1 years were divided into two groups (20 BMG patients and 20 healthy controls) and had their taste function assessed in relation to four basic tastes: bitter, sour, sweet, and salty.

RESULTS

All participants in the case group exhibited lesions over the dorsum, edges and tip of the tongue with a possible extension to the surface below. No statistic difference was observed between BMG patients and controls for the taste scores (Mann-Whitney U test: P=0.0955). The percentage of correctly identified taste strips for the highest concentrations was 100% for all tastes. For the lowest concentrations it was 85% for sweet, 50% for sour, 95% for salty, and 95% for bitter. Three patients with BMG and three control subjects showed hypogeusia.

CONCLUSION

This study revealed that BMG is not able to change the perception of taste for salty, sweet, sour and bitter.
