The Use of Functional Confections in Promoting Oral Health
A Pilot Phase I Study of the Use of Functional Confections in Promoting Oral Health in Men and Women
In areas of the world where populations are undernourished poor oral health is prevalent. Diets rich in fruit and vegetables are thought to have many health benefits including reducing the risk of oral cancer or gum disease. In particular fruits such as strawberries contain many different compounds which may be responsible for these proposed health benefits.
From this study, the researchers hope to gain information about how the tissues in the mouth absorb strawberry gummies in a population of habitually smoking and never smoking men and women. The researchers will measure inflammation hormones in your saliva and urine and the genes in your mouth and blood. Two different strawberry gummies will be tested in this study. The strawberry gummies were developed at OSU in the Department of Food Science and Technology. One type of strawberry gummy will contain freeze-dried whole strawberries while the other type will have no fruit. In total the eight pieces of strawberry gummies that you will consume in one day will be at most equal to 1 cup of whole strawberries. The research team believes the two strawberry gummies may be digested and absorbed differently and that components in the strawberry gummies may be helpful for oral health.

Detailed Description
Polyphenols (plant chemicals, some produce purple and red color in fruits) found in strawberries have been associated with reducing the risk of gum disease. However, much of these chemicals are susceptible to degradation during food processing and digestion. Minimally degraded in the mouth, polyphenols when consumed as fresh fruits are retained only for brief periods. Therefore, exposure of fresh fruit polyphenols to oral tissues may not be adequate for a biologic effect to occur. At OSU, food scientists have developed a 6 gram strawberry gummy containing 3 grams of freeze-dried strawberries designed to dissolve relatively slow in the mouth.
The investigators will investigate the effects of strawberry gummy consumption on oral health in 36 habitually smoking and non-smoking healthy adults (men and women). At the enrollment visit (Day-14), subjects will visit the OSU Clinical Research Center (CRC) for an oral brushing; submit a 24-hour urine collection, and a saliva sample. Subjects will then start an anthocyanin-free (avoid purple and red fruits and vegetables) diet which they will maintain for 6 weeks of this study. After 2 weeks, subjects will have their first "washout" visit at the CRC. This visit will be one of two "washout visits" where subjects will again submit samples (fasting blood, urine, saliva, and oral brushing). At this visit, smokers will be block randomized (random assignment using computer software) into one of two groups (strawberry or placebo gummies) with a matching non-smoker having the same gender and age group. A salivary pharmacokinetic (sPK) study will follow and involves collection of saliva at these time points: 5 minutes before gummy placed in the mouth, and at 5,10,15,20,25, and 30 minutes after gummies have been in the mouth. Subjects will be instructed to consume 2 pieces of strawberry, or placebo gummy 4 times a day for 7 days. After 7 days subjects return to the CRC for a "treatment visit" to submit fasting blood, urine, saliva and oral brushing samples. Subjects will repeat the two-week anthocyanin-free diet and return to the CRC for another "washout visit" before crossing over to the other study gummy. After 7 days of gummy consumption, subjects will return for their second treatment visit and submit fasting blood, oral brushing, saliva, and 24 hour urine collection.

Description
Inclusion Criteria:
- Submit to a 24 hour urine cotinine test which will be used to determine smoking status.
- Meet one of the following smoking criteria
Non-smoker
- Does not currently smoke or has no history of smoking or using tobacco related products (cigarettes, cigars, pipe, snuff, or chewing tobacco) or smoking any non-tobacco related products and urine cotinine (less than 100 ng/mL

- Abstain from the use of ANY mouth washes (commercial or home remedies)during 6 week study period
Exclusion Criteria
- Have a known allergy to strawberries, corn, and wheat products or those who have never consumed any of these products.
- Have active metabolic or digestive illnesses such as malabsorptive disorders (Crohn's, ileus, IBS), renal insufficiency, hepatic insufficiency, hyper- or hypothyroidism, cachexia, morbid obesity, or short bowel syndrome.
- Have a history of pituitary hormone diseases that currently require supplemental hormonal administration (thyroid hormones, ACTH, growth hormone, insulin) or other endocrine disorders requiring hormone administration.
- Have significant loss of gastrointestinal organs due to surgery, except for appendix.
- Have altered immunity such as chronic inflammatory disease, autoimmune disorders, cancer, anemia, hemophilia, and blood dyscrasias.
