Atraumatic Restorative Treatments in Australian Aboriginal Communities: A Cluster-randomized Trial

Area of Science:

• Public Health
• Pediatric Dentistry
• Indigenous Health

Background:

• Early Childhood Caries (ECC) presents significant management challenges, particularly in remote settings.
• Existing dental care models often struggle to reach or effectively serve vulnerable populations like Aboriginal children in remote Australia.

Purpose of the Study:

• To evaluate a novel care model, the Atraumatic Restorative Treatment and Hall Technique (ART-HT), for managing ECC in remote Aboriginal communities.
• To compare the effectiveness of the ART-HT intervention against standard care options for early childhood caries.

Main Methods:

• A cluster-randomized trial involving 25 remote Aboriginal communities in Western Australia.
• Children received either early intervention (ART-HT) or delayed intervention (standard care) for ECC management.
• Assessments at baseline and 11-month follow-up included caries experience, with multivariate analysis using generalized estimating equations (GEE).

Main Results:

• The ART-HT intervention group showed significantly more filled teeth (1.2 vs. 0.2) and fewer decayed teeth compared to the control group at follow-up.
• Multivariate analysis indicated increased rates of untreated decayed teeth (RR=1.4) and decreased filled teeth (RR=0.2) in the control group.
• The study achieved 68% retention, with 231 children examined at follow-up.

Conclusions:

• A minimally invasive, atraumatic care model (ART-HT) effectively improved oral health outcomes for young children (<6 years) in remote Aboriginal communities.
• The ART-HT approach resulted in increased dental care delivery and better oral health compared to standard care.
• This model demonstrates potential for integration into mainstream dental service delivery programs.
