Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will be consented, enrolled, and randomly assigned to a control group (no dog) or to an experimental group with dog present only before their dental visit for 3 minutes (+ Short AAT) or to an experimental group with dog present throughout their entire visit (+ Long AAT). Control (no dog) patients will have an active control where they color for 3 minutes before their dental exam, cleaning, and simulated radiographs, without a dog present. Biometric data will be collected with a small wireless wrist device (Shimmer 3) which measures heart rate and sweat response (skin galvanic response). Salivary samples will be taken before and after the dental visit to measure salivary cortisol and amylase, as a metric of physiological stress. Finally, a video feed of body movements during the dental visit will be collected for observational coding. Pre-visit and post-visit surveys will be given to all the patients on their experiences regarding pain, anxiety, and perceptions of the dental experience.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

4 years to 8 years (Child)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria: Subjects must meet all of the following inclusion criteria to be eligible for enrollment in the study:

  • 4-8 years of age
  • English speaking
  • Qualifies for a dental exam and prophylaxis (cleaning) by having not received a dental prophylaxis or oral exam in the past 3 months
  • Stable physical health, decided at the discretion of the study coordinator and PI
  • Able to comprehend and follow the requirements of the study (including availability on scheduled visit dates) based on research site personnel's assessment
  • Evidence of a personally signed and dated informed assent form from the child and legal guardian's consent document indicating the subject (or legally acceptable representative) has been informed of all pertinent aspects of the trial and all of their questions have been answered

Exclusion Criteria: Subjects presenting with any of the following will not be included in the study:

  • Patients <4yo and >8yo
  • Non-English speakers
  • Patients unwilling to assent/participate or parental/guardian consent was not given
  • Self-report or parental report of patient suffering current dental pain
  • Known allergies or significant adverse reactions following exposure to dogs or the use of oral hygiene products (toothpastes, mouth rinses), and all ingredients in prophy paste
  • Children who are afraid of dogs or had a prior negative experience with dogs as reported by the parent or child
  • Severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with trial participation or may interfere with the interpretation of trial results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this trial
  • Developmental/cognitive disability such that patient cannot self-assent, comprehend and follow the requirements of the study based on research site personnel's assessment
