Sensory Adaptations to Improve Physiological and Behavioral Distress During Dental Visits in Autistic Children: A Randomized Crossover Trial.

Importance: Autistic children have poorer oral health and greater oral care challenges, which are often associated with sensory overresponsivity, than neurotypical peers. It is important to identify innovative solutions enabling dentists to successfully perform standard clinic-based procedures for this population. Objective: To determine whether a sensory-adapted dental environment (SADE) reduces physiological and behavioral distress in autistic children undergoing dental cleanings, compared with a regular dental environment (RDE). Design, Setting, and Participants: This randomized crossover trial was conducted at a pediatric dentistry clinic in a large urban children's hospital between May 2016 and April 2022. Coders were blinded to study condition for physiological but not behavioral measurements. Autistic children aged 6 to 12 years were identified and invited to participate. Interested families were enrolled consecutively; after confirmation of autism diagnosis, children were randomized. Analysis for this per-protocol study were conducted from April to October 2022. Intervention: Each child underwent 1 RDE and 1 SADE dental cleaning, administered in randomized and counterbalanced order approximately 6 months apart. SADE included modified visual, auditory, and tactile stimuli. Main Outcomes and Measures: The primary outcome was physiological stress, assessed by electrodermal activity. The secondary outcome was behavioral distress measured from video recordings. Results: Among 452 families invited to participate, 220 children were enrolled, and 162 children (mean [SD] age, 9.16 [1.99] years; 136 [84.0%] male) with confirmed autism were randomized, with 83 children receiving RDE first and 80 children receiving SADE first. Most children (94 children [58.0%]) had moderate autism severity. Children had significantly lower physiological stress during dental care in SADE compared with RDE (mean difference in skin conductance level, -1.22 [95% CI, -2.17 to -0.27] µS), suggesting decreased sympathetic activity and increased relaxation during SADE dental care. No significant differences were found in nonspecific skin conductance responses (mean difference, -0.30 [95% CI, -0.86 to 0.25] per min). Video-coded frequency and duration of behavioral distress (but not questionnaire) measures were significantly lower in SADE vs RDE (Cohen d = -0.84 to -1.19). Physiological stress was associated with behavioral distress during the dental cleaning (eg, nonspecific skin conductance responses associated with the Frankl Scale: ß = -0.29; 95% CI, -0.39 to -0.19); age, IQ, and expressive communication moderated the intervention's success. No participants withdrew due to adverse effects. Conclusions and Relevance: In this randomized crossover trial of autistic children, using SADE was safe and efficacious in decreasing physiological and behavioral distress during dental care. This is important because enhancing oral care is critical for autistic children; this intervention may also be beneficial for populations beyond autism.

Oral Health Barriers for African American Caregivers of Autistic Children.

The most persistent oral health disparities in the United States impact children from racial and ethnic minoritized groups and children diagnosed as autistic. This paper aims to describe barriers to oral care as depicted by Black/African American (B/AA) parents of autistic children to further explore how and why oral health disparities persist in this population. A purposeful sample of eleven caregivers of autistic children, ages 4 to 14 years, who identified as B/AA were interviewed twice for approximately 60-90 min each. Thematic analysis utilizing a narrative approach was employed. Three themes emerged from the data concerning the barriers that affect oral health experiences: (a) difficulty in maintaining good oral health practices, (b) challenges with access to care and resources, and (c) poor patient-provider relationships. Due to the limited research that examines the intersection of autism, B/AA culture, and oral health practices, this study provides a rich picture of the barriers families face when obtaining oral care. Many families raised issues that other parents of autistic children also identified. B/AA caregivers have demonstrated that despite their own negative dental experiences, they understand the value of good oral care practices and are willing to pursue oral care for their children.

Oral Care Knowledge, Attitudes, and Practices of Black/African American Caregivers of Autistic Children and Non-Autistic Children.

Oral health is a vital component of overall health. Children from underserved, minoritized populations (i.e., Black/African Americans, autistic children) are at even greater risk for experiencing oral health disparities. This study aims to illuminate the oral health knowledge, attitudes, and practices of Black/African American caregivers of autistic and non-autistic children. Black/African American caregivers of children (4-to-14 years) on the autism spectrum (n = 65) or not on the autism spectrum (n = 60), participated in a survey, with input from literature reviews, interviews, previous research, and reviews by experts. Caregivers demonstrated basic knowledge of oral health with significantly lower scores for caregivers of autistic children. Caregivers care about oral health and would like to increase their knowledge. Significant differences in oral care practices were found between the autistic and non-autistic groups. Caregivers reported they can access dental services with relative ease, including finding their child a dentist, scheduling a dental appointment, and accessing transportation (personal or public) to attend the visit. Black/African American caregivers of autistic children and children without autism seem to have foundational knowledge about oral health and basic practices; however, they are interested in learning more. Therefore, tailored oral health education programs may help mitigate oral health disparities for Black/African American families.
