Outcome Measures

Primary Outcomes (9)

  • Mean Heart Rate during Dental Exam

    Beats per minute during dental exam. Heart rate measured using wrist-worn Shimmer heart rate tracking device.

    During dental exam, approximately 2- 5 minutes.

  • Mean Heart Rate during Dental Cleaning

    Beats per minute during dental cleaning. Heart rate measured using wrist-worn Shimmer heart rate tracking device.

    During dental cleaning, approximately 2- 5 minutes.

  • Mean Heart Rate during Dental Radiograph Simulation

    Beats per minute during dental radiograph simulation. Heart rate measured using wrist-worn Shimmer heart rate tracking device.

    During dental radiograph simulation, approximately 2- 5 minutes.

  • Salivary Cortisol during Dental Exam

    To measure stress levels salivette swab will be placed in child's cheek to absorb saliva. Swabs are spun down for extraction and saliva sample will undergo ELISA assay to measure cortisol level.

    During dental exam, approximately 1-2 minutes.

  • Salivary Cortisol during Dental Cleaning

    To measure stress levels salivette swab will be placed in child's cheek to absorb saliva. Swabs are spun down for extraction and saliva sample will undergo ELISA assay to measure cortisol level.

    During dental cleaning, approximately 1-2 minutes.

  • Salivary Cortisol during Dental Radiograph Simulation

    To measure stress levels salivette swab will be placed in child's cheek to absorb saliva. Swabs are spun down for extraction and saliva sample will undergo ELISA assay to measure cortisol level.

    During dental radiograph simulation, approximately 1-2 minutes.

  • Salivary Amylase during Dental Exam

    To measure stress levels salivette swab will be placed in child's cheek to absorb saliva. Swabs are spun down for extraction and saliva sample will undergo ELISA assay to measure cortisol level.

    During dental exam, approximately 1-2 minutes.

  • Salivary Amylase during Dental Cleaning

    To measure stress levels salivette swab will be placed in child's cheek to absorb saliva. Swabs are spun down for extraction and saliva sample will undergo ELISA assay to measure cortisol level.

    During dental cleaning, approximately 1-2 minutes.

  • Salivary Amylase during Dental Radiograph Simulation

    To measure stress levels salivette swab will be placed in child's cheek to absorb saliva. Swabs are spun down for extraction and saliva sample will undergo ELISA assay to measure cortisol level.

    During dental radiograph simulation, approximately 1-2 minutes.

Study Arms (3)

+Short AAT

EXPERIMENTAL

Children aged 4-8 y.o. willing to receive an oral exam, a toothbrush cleaning, simulated radiographs and be a study participant - 75 experimental patients who will be interacting with the dog prior to their oral exam.

Behavioral: +Short AAT

+Long AAT

EXPERIMENTAL

Children aged 4-8 y.o. willing to receive an oral exam, a toothbrush cleaning, simulated radiographs and be a study participant - 75 experimental patients who will be interacting with the dog throughout their entire visit.

Behavioral: +Long AAT

Active control; NO dog

ACTIVE COMPARATOR

Children aged 4-8 y.o. willing to receive an oral exam, a toothbrush cleaning, simulated radiographs and be a study participant - 75 control patients who will not be interacting with the dog during their visit and will color a dog picture for 3 minutes instead.

Behavioral: Active control; NO dog

Interventions

+Short AATBEHAVIORAL

Interaction with therapy dog prior to dental exam, cleaning, and simulated radiographs.

+Short AAT
+Long AATBEHAVIORAL

Interaction with therapy dog throughout dental exam, cleaning, and simulated radiographs.

+Long AAT

Color dog picture for 3 minutes prior to dental exam, cleaning, and simulated radiographs.

Active control; NO dog

Eligibility Criteria

Age4 Years - 8 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • 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

You may not qualify if:

  • 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
