Oral Health Interventions to Improve Access in Rural Areas of High-Income Countries: A Mixed Methods Systematic...

Area of Science:

• Public Health
• Health Services Research
• Rural Health

Background:

• Access to dental services in rural areas of high-income countries is a persistent challenge.
• Existing oral health interventions often focus on small-scale initiatives with limited evaluation.

Purpose of the Study:

• To identify oral health interventions in rural, high-income settings.
• To synthesize evidence on how these interventions address access to dental care.

Main Methods:

• A mixed methods systematic review of studies published since 2000.
• Searches across multiple databases (Cochrane, CINAHL, PubMed, etc.).
• Thematic synthesis guided by the Penchansky and Thomas model of access.

Main Results:

• 73 articles were included, reporting mostly small-scale interventions by dental and primary health providers.
• Fluoride varnish, treatments, and health promotion were common; telehealth and low-cost options addressed access barriers.
• Few studies evaluated community acceptability or addressed all dimensions of access; study quality varied significantly.

Conclusions:

• A lack of robust, well-evaluated studies hinders progress in rural oral health.
• Future interventions must prioritize equity, community engagement, prevention, and integrated care.
• Ensuring access to quality oral healthcare is a fundamental human rights and equity issue for rural populations.
