The effects of a therapy dog intervention on dental fear and anxiety in adult patients undergoing dental procedures: a pilot study.

Dental anxiety poses challenges for providing effective oral healthcare. While therapy dogs have shown promise in various medical and mental health contexts, their use for alleviating dental anxiety in adults remains underexplored. This study aimed to investigate the emotional and physiologic effects of therapy dogs on self-reported dental anxiety. Adults with dental anxiety were randomly assigned to an intervention group (DOG; n = 19) or a standard care group (SC; n = 14). Standard self-report measures were used to assess dental anxiety (Index of Dental Anxiety and Fear [IDAF-4C+]), depression (Patient Health Questionnaire 9), and generalized anxiety (Generalized Anxiety Disorder 7) prior to the intervention. Participants in the DOG group received a 10-minute therapy dog intervention before dental procedures in sessions 1 and 2, while participants in the SC group rested quietly for 10 minutes before their procedure. The SC participants received the 10-minute therapy dog intervention before dental procedures in the third and final session, while patients in the DOG group received no intervention prior to their third procedure. After the dental procedures, patients completed a questionnaire about their satisfaction with the dog therapy (Therapy Satisfaction Scale) and recorded their anxiety and comfort levels on visual analog scales. Continuous electrocardiographic recording measured heart rate variability during the intervention and dental procedure. Prior to the intervention, most participants (90.9%) met the IDAF-4C+ criteria for dental anxiety, with 7 (21.2%) meeting the criteria for dental phobia. The DOG group participants expressed high satisfaction with the therapy dog intervention. No significant differences in heart rate variability were observed between the groups during dental procedures. Therapy dogs can effectively manage dental anxiety in adults with mild to moderate dental anxiety, offering potential benefits for oral healthcare.
