Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Experimental: Toothpaste detergents with Eosinophilic Esophagitis Testing
Subjects will complete an esophageal string test prior to and after completing a high resolution esophageal manometry then brushing their teeth using Colgate toothpaste.
Diagnostic Test: - Esophageal String Test (EST)
Non-invasive, FDA-registered sampling method to evaluate eosinophilic inflammation in the esophagus. The EST is performed by having an individual swallow a capsule attached to a string which captures secretions from the esophagus. The end of the string is taped to the cheek and the capsule is swallowed with water. After 1 hour, the EST will be removed, and the string will be processed for laboratory analysis.
Other: - Colgate
2 grams of toothpaste (pea sized amount) for 2 minutes
Diagnostic Test: - High Resolution Esophageal Manometry (HREM)
Thin flexible tube with sensors placed in the nose and swallowed for esophagus placement to conduct reading regarding the lining of the esophagus taken for approximately 10 minutes
