Abstract

Introduction: Taste buds are peripheral structures responsible for
sensing taste compounds in food and drink. Each taste bud contains a
number of specialized epithelial cells, including taste receptor cells for
recognizing sweet, bitter, umami, sour, and salty compounds. Some of
the subjective variability attributed to taste experience could be related
to wide variations of taste bud density. The aim of the present study
is to investigate histologic changes of taste buds in fungiform papillae
of geriatric age groups by histo morphometric study in Mysore based
population
Material and Method: Taste bud densities are quantified in this study
using trinocular research microscope and reconstructed two regions of
30 human cadaver tongues. Specimens were collected from male and
female cadavers representing geriatric adult age (65-80 years ).
Results: Mean wall length of fungiform papillae was 0.09 0.4
and 0.08 0.2 in males and females respectively. Taste bud density
(Mean/cm SD) was 102.2 1.2 in males and 111.2 2.3 in females.
Conclusion: Recent studies suggest that disruption or alteration of taste
bud homeostasis may contribute to taste dysfunction associated with
disease and aging. Differences in taste bud density that extend across
adult age groups probably confound some inferences about the effects
of aging on taste sensitivity that are derived from cross-sectional studies
of human populations.
