About
The goal of this effectiveness trial is to investigate if an integrated dental habituation programme can enhance acceptance of a clinical dental examination in children (aged 5-8 years) with autism spectrum disorder (ASD).
The main questions it aims to answer are:
The study participants will be randomly assigned to either the habituation group (intervention) or the home preparation group (augmented control) to investigate the effectiveness in increasing acceptance and cooperation of a clinical dental examination.
Full description
BACKGROUND Autism Spectrum Disorder (ASD) is a developmental disorder characterized by deviations in language, communication, social interaction, and a restricted and repetitive pattern of activities and interests. Good oral health is crucial for life satisfaction and impacts general health, nutrition, appearance, and communication. Several studies have shown that children with ASD often face challenges during oral examinations and dental treatments. Increased stress and anxiety in these patients also make dental treatment challenging for caregivers and the dental team. Various studies have demonstrated that communication aids, such as visual tools (pictures, books, films), and familiarization techniques (e.g., tell-show-do), can reduce stress and increase cooperation during dental examinations. Studies indicate that knowledge about ASD among healthcare professionals is limited. Despite continuous improvements, there is significant variation in knowledge levels across different age groups and professional backgrounds. A lack of knowledge and confidence in their skills among healthcare professionals can result in poorer healthcare services for children with ASD. Sufficient knowledge and early intervention are essential for achieving positive outcomes for this patient group.
METHODS
Design and Procedures:
To address this challenge and enable more dental examinations at local clinics, the investigators have developed a training program for dental personnel. The course, developed by pediatric dentists, was presented to a resource group consisting of a psychologist, a dental hygienist, dentists, a researcher, and a parent of a child with ASD. Adaptations were made based on feedback from the resource group. The course includes both theoretical and practical content, focusing on ASD characteristics, communication techniques, and tools specific to this patient group to increase cooperation and the completion of clinical dental examinations. During the course, dental personnel will be trained in a habituation program to provide a gradual and structured approach to dental examinations, minimizing unwanted behavior and reducing perceived stress in the child, parent, and dental practitioner. To the effectiveness of the integrated habituation program will be evaluated in a randomized controlled trial. The intervention will last for 5 weeks, with one habituation session each week. The habituation sessions will be performed at selected dental clinics. Clinics will be selected based on geographical location, and on the affiliation of the dental hygienist participating in the study.
Participants will be recruited from two counties in western Norway (Rogaland and Vestland) and randomly assigned to either the intervention group or an augmented control group. The augmented control group will receive a toolbox with visual aids for home preparation before a dental appointment, similar to the intervention group. Participation will be based on written informed consent provided by the parents og caregivers of the children.
Measurements:
The effects of the habituation program will be assessed based on the successful completion of a clinical dental examination. Additionally, changes in cooperation (using the Frankl scale) during each session will be recorded. Parents will be asked to fill out a mapping form at baseline, and clinical data from patient journals will be collected. Child stress will be measured using the Wong Baker FACES® scale. In addition, following the intervention, both parents and dental hygieneists will be invited to an interview to share their experiences as part of the evaluation of the study.
Power and Sample Size:
The estimation of sample size is based on a binary logistic model with a random effect factor. 1000 Monte Carlo simulations indicate that 225 children are needed to provide satisfactory power, given that the difference in the probability of success is not less than 0.2. However, there is uncertainty associated with the calculations since previous studies, which formed the basis for this calculation, differ from this study in several ways (e.g., different age and setting, different steps in the habituation program). It was calculated that at least 6 dental hygienists are needed to participate in the study and perform the habituation program.
Data Analysis:
The statistical software package SPSS (IBM) will be used to analyze quantitative data such as questionaire data, Frankl scale data, and clinical data from patient journals. The analyses will include descriptive statistics and statistical tests to identify changes and differences in the study variables within and between the intervention and control groups (e.g., t-tests, mixed-effects models). It is hypothesized that the use of the habituation program will lead to increased cooperation and completion of clinical dental examinations, and a reduction in child and parental stress in this setting. Regression analysis will be employed to investigate associations between study variables while adjusting for potential covariates. NVivo (Alfasoft) will be used to analyze additional qualitative data from patient journals.
