Geriatric oral health and its impact on eating.
OBJECTIVE: Adequate food and fluid intake and nutritional health are requisites for sustaining life. The oral-pharyngeal region has evolved multiple, highly regulated processes to ensure that the intake, chewing, and swallowing of foods and beverages is maintained. The objective of this paper is to identify the independent and collective roles of oral health on eating in older people. DESIGN: Research reports from peer-reviewed scientific journals. Hypothesis-driven research that objectively examined taste, smell, dental and oral mucosal health, dental prostheses, chewing, and swallowing in the context of aging. DATA EXTRACTION AND SYNTHESIS: Data results were extracted independently by multiple observers. A qualitative synthesis of data results from independent studies was made in order to form conclusions regarding the role of oral health on eating in older people. CONCLUSIONS: Many oral functions remain intact in healthy older adults. However, significant alterations arise from oral and systemic diseases and their treatments, and these may have a profound effect on eating, drinking, and the nutritional status of older individuals. The care of older persons with smell, taste, dental/alveolar, oral mucosal, chewing, and swallowing problems requires a multidisciplinary team of health care providers. Recognition of the interrelationship between oral, pharyngeal, and systemic physiological processes will help practitioners identify the etiology of these disorders and implement appropriate therapy.

Oral capsaicin provides temporary relief for oral mucositis pain secondary to chemotherapy/radiation therapy.
Pain from oral mucositis afflicts from 40% to 70% of patients receiving chemotherapy or radiation therapy. Current methods of clinical pain management (for example, topical anesthetics, systemic analgesics) have limited success. In a pilot study, we examined the ability of oral capsaicin to provide temporary relief of oral mucositis pain. Capsaicin, the active ingredient in chili peppers, desensitizes some neurons and has provided moderate pain relief when applied to the skin surface. Oral capsaicin in a candy (taffy) vehicle produced substantial pain reduction in 11 patients with oral mucositis pain from cancer therapy. However, this pain relief was not complete for most patients and was only temporary. Additional research is needed to fully utilize the properties of capsaicin desensitization and thus optimize analgesia.

Propylthiouracil tasting: determination of underlying threshold distributions using maximum likelihood.
The ability to taste low concentrations of propylthiouracil (PROP) and related bitter compounds is heritable. The current analysis determines whether the distribution of PROP taste thresholds is consistent with an additive or a dominant mode of Mendelian transmission. To that end, the lowest concentration of PROP detectable was determined for 1015 subjects and models of bi- or tri-modal distributions of PROP taste thresholds were tested. The model with the greatest likelihood had three distributions and followed an additive model of PROP taste sensitivity if the variances associated with the distributions were assumed to be equal. However, if the taste thresholds were transformed to remove skewness, or if the variances were unequal, then three- or two-distribution models were equally likely. Resolution of the mode of inheritance for bitter taste perception awaits additional family studies and the characterization of the molecular basis of taste perception for these bitter compounds.
