Sensory Adapted Dental Environments to Enhance Oral Care for Children (SADE-2)

Sensory Adapted Dental Environments to Enhance Oral Care for Children (SADE-2)

The goal of this project is to examine the efficacy of a sensory adapted dental environment (SADE) for children who have difficulty tolerating oral care in the dental clinic. The investigators hypothesize that adapting the sensory environment in the dental office by modifying the sounds, sights,and tactile experiences will result in decreased anxiety, increased cooperation, and fewer behavior problems for children with Autism Spectrum Disorders (ASD). This has the potential to contribute to increased child comfort as well as safer, more efficient, and less costly treatment for a large population, as potentially more than one-fourth of all children may benefit from a sensory adapted dental environment.

Study Overview

• Status: Active, not recruiting
• Conditions: Autism
• Intervention / Treatment: Behavioral: Sensory Adapted Dental Environment

Detailed Description

This project, which builds upon the investigator's previous R34 National Institute of Dental and Craniofacial Research (NIDCR) Planning and Feasibility study, is designed to examine the efficacy of a sensory adapted dental environment (SADE) to enhance oral care for children with autism spectrum disorders (ASD). Children with ASD often exhibit sensory over-responsivity when confronted with experiential aspects of dental visits such as exposure to bright fluorescent lighting, touch in or around the mouth, or the texture and smell of various oral care products. This often results in increased anxiety and negative behavioral responses which hinder the dentist's ability to perform treatment. In the proposed project, the investigators test a SADE intervention designed to reduce children's anxiety and negative responses during oral care.

The SADE intervention includes adaptations such as dimmed lighting, moving projections on the ceiling (fish, bubbles), exposure to soothing music, and application of a butterfly vest with wings that wrap around the child to provide calming sensations.

The specific aims are to conduct a randomized clinical trial in order to:

1. Determine if SADE, relative to a regular dental environment (RDE), reduces physiological anxiety and negative responses (behavioral distress, perception of pain, sensory discomfort) during dental cleaning for children with ASD.
2. Identify whether physiological anxiety mediates the beneficial effects of the intervention and whether severity of ASD and communication ability, or dental anxiety, sensory over-responsivity, and age act as moderating variables.
3. Assess the quality of care and cost effectiveness/savings of the dental cleaning associated with SADE.

Research participants will be 220 ethnically diverse children aged 6-12 years. Using a randomized counterbalanced study design, each child will undergo two dental cleanings four months apart: one dental cleaning in RDE and one dental cleaning in SADE.

This project is significant because it is the first full-scale trial of an intervention designed to reduce oral care problems in children with ASD. It is theoretically important because it will elucidate the mechanisms that underlie the effects of the SADE intervention. Based on the study findings, the investigators will develop a model to transform the standard of pediatric dental care by modifying the sensory qualities of the dental environment. This model will have the potential to be utilized in dental clinics worldwide. As such, the project promises to have a major public health impact insofar as the potential gains in oral health, child comfort, and cost-savings will be dramatic, potentially applying to more than one-fourth of all children.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: Regular Dental Environment; There are two dental environments - the regular dental environment and the sensory dental environment; each child will be randomized to which is first. In the Regular dental environment no sensory characteristics of the dental environment are altered, the cleaning is conducted as per usual.
Experimental: Sensory Adapted Dental Environment; In the Sensory Adapted Dental Environment the sensory characteristics of the dental environment are altered (visual, auditory, tactile adaptations).	Behavioral: Sensory Adapted Dental Environment; The SADE intervention includes adaptations such as dimmed lighting, moving projections on the ceiling (fish, bubbles), exposure to soothing music, and application of a butterfly vest with wings that wrap around the child to provide calming sensations.; Other Names: SADE Intervention

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Electrodermal Activity (EDA)	Electrodermal activity (EDA) is a non-invasive measure of the ability of the skin to conduct an electrical current, which increases when the sympathetic "fight or flight" nervous system is activated during times of stress. EDA will be analyzed in two ways in this study to investigate physiological stress/anxiety: (1) tonic skin conductance level (SCL) and (2) frequency of non-specific skin conductance responses (NS-SCR).	Recorded continuously for three minutes prior to cleaning, through duration of cleaning (approximately 10-45 minutes), and for three minutes at end of cleaning for each dental cleaning.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Children's Dental Behavior Rating Scale (CDBRS)	The Children's Dental Behavioral Rating Scale (CDBRS) evaluates overt distress behaviors exhibited by children in the dental office. The child's behavior is videotaped during the dental cleaning; the first five minutes of prophylaxis are coded from the video data at a later date. Coding included marking the presence or absence of three distress behaviors (mouth movement, head movement, forehead movement) and the presence or absence and the severity of two distress behaviors (whimper/cry/scream, verbal stall or delay) during each one-minute interval of the five minute video. Significant inter-rater reliability by two trained raters on a sample of children with and without ASD was obtained. The raw score (0-45) was converted, via Rasch analysis, to a scale score of 1-100.	Videorecorded throughout dental cleaning (approximately 10-45 minutes); coded at a later time for the first five minutes of dental prophylaxis.
Anxiety and Cooperation Scale	The Anxiety and Cooperation Scale (A & C Scale) has been shown to assess children's anxiety, fear, and cooperation as rated by dentists, and has good established reliability and validity. Following a routine dental cleaning, the dentist rated overall patient behavior during treatment using a one-item Likert scale ranging from 0 (relaxed, smiling, demonstrates desired behavior, complies with demands) to 5 (out of control, loud crying, reverts to primitive flight responses, physical restraint required).	Completed at the end of each dental cleaning (approximately 1 minute)
Duration	The length of time to complete the dental cleaning. Used for cost-analysis of the intervention.	Time from beginning to end of dental cleaning (approximately 10-45 minutes); recorded for each visit
Number of hands used to restrain child	The maximum number of hands (at any one time) required to restrain the child during the dental cleaning experience was utilized as a measure of cost and also a measure of uncooperative behavior. This variable was recorded on researcher notes during the dental cleaning and was verified using the videotape of the dental cleaning. Scoring included presence/absence as well as the number of hands used for restraint purposes during the cleaning.	Recorded throughout the dental cleaning (approximately 10-45 minutes)
Faces Pain Scale - Revised	Faces Pain Scale is a valid tool comprised of six faces to assess perception and intensity of pain.	Completed at the end of each dental cleaning (approximately 1-2 minutes)
Dental Sensory Sensitivity Scale	Dental Sensory Sensitivity Scale describes the presence and magnitude of discomfort with different sensory stimuli in the dental environment.	Completed at the end of each dental cleaning (approximately 3 minutes)
Frankl Scale	The Frankl Scale was completed by the dentist following the dental cleaning. This one-item Likert Scale ranges from 1 (definitely negative) to 2 (negative) to 3 (positive) to 4 (definitely positive). This assessment has high inter-rater reliability and moderate validity and has been used to measure the behavior of children with ASD.	Completed at the end of each dental cleaning (approximately 1 minute)
