Taste Testing: Purpose, Procedure, Interpretation

Several factors can contribute to adult taste and smell disorders, including metabolic and endocrine abnormalities, neurological disorders, inflammatory conditions of the nasal passages and paranasal sinuses, head trauma and surgery, infections, chemical exposures, medications, and normal aging. Flavor perception can be significantly impacted by problems with taste and smell, which can lower quality of life and make it difficult to obtain enough nourishment. Many things that people think are flavor flaws are, in fact, the result of a problem with their sense of smell. The flavor is a multisensory experience originating from the food’s aroma, taste, texture, and warmth. When food is introduced to the mouth, it stimulates several different taste buds. Disorders of the oral cavity and mucosa, such as infections, inflammation, and radiation-induced mucositis, can diminish the ability to taste. Since taste buds are typically considered radioresistant, the microvilli of the taste buds are likely to be the site of harm during irradiation. Hypogeusia and cacogeusia are often the result of neglectful dental care. Secondary taste bud involvement is a potential cause of taste abnormalities caused by infections with viruses, bacteria, fungi, and parasites.
