Impact of Therapy Dogs on Child Anxiety and Behavior During Local Anesthesia for Dental Procedures
What this study is about
Therapy dogs in dental offices might help anxious children during dental care. Therapy dogs might help children during injection of local anesthetic, when we inject numbing medication before working on the teeth. The goal of this study is to learn if having a therapy dog with a child during the injection of numbing medication helps children to be more comfortable at the dentist's office.
View original scientific description
Therapy dogs in dental offices might help anxious children during dental care. Therapy dogs might help children during injection of local anesthetic, when we inject numbing medication before working on the teeth. The goal of this study is to learn if having a therapy dog with a child during the injection of numbing medication helps children to be more comfortable at the dentist's office. This study is of children who need dental care using local anesthesia. Study participant's behavioral reactions and heart rate during injection of local anesthetic with and without having a therapy dog present will be recorded and children and their guardians will be asked a few short questions about the injection and therapy dog after injection.
Interventions
BEHAVIORAL
Therapy dog presence
A trained therapy dog will be present during the child's dental appointment. The dog will be in the operatory as the child enters the room and will lie on the child during injection of local anesthesia.
BEHAVIORAL
Standard-of-care basic behavior guidance
Basic behavior guidance as defined by the American Academy of Pediatric Dentistry includes strategies to help children cope through potentially stressful dental procedures. These strategies include tell-show-do, positive reinforcement, parental presence, and nitrous oxide/oxygen analgesia, among others.
Primary outcome measures
Behavior (Face, Legs, Activity, Cry, and Consolability scale)
Time frame: Every 30 seconds from entry into the operatory through one-minute following injection of local anesthesia
The subject's behavior from entry into the operatory through one minute following administration of local anesthesia will be evaluated and recorded using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale, with each category scored from 0 to 2. The higher the total score, which ranges from 0 to 10, indicates more distress.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- Verbal assent from potential subjects age 4-9 years; written assent for children age 10-12 years
Exclusion criteria
- Allergies: children with known allergies to dogs or animal dander
- Children with a fear or phobia of dogs
- Children with a behavioral disorder which may negatively impact response to the presence of a therapy dog
- Previous exposure: children who have previously undergone dental procedures with local anesthesia in the presence of a therapy dog
- Medical conditions: children with medical conditions that might affect their vital signs independently of the dental procedure (e.g., heart conditions)
- Parental discomfort: cases where parents are uncomfortable with the presence of a therapy dog during the procedure

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
