Primary dental health aide (PDHA) service-delivery models (PDHA program; PDHA + intensive staffing; PDHA + robust prevention) vs Baseline pre-intervention service-delivery scenario

Projected Significant Caries (SiC) index · Alaska Native children (below age 18)

A simulation projected a 50% drop in the Significant Caries index for children (12.3 to 6.1) under the PDHA model (certainty not graded).

DHAT-delivered dental care vs Dentist-delivered dental care

Technical performance / deficient restorations (DHATs vs dentists) · Alaska Native dental patients (children aged 6-17 and adults) and their caregivers

DHATs had a lower amalgam restoration deficiency rate than dentists (12% vs 22%; certainty not graded).

Hyperbaric oxygen vs No HBO therapy

Prosthetic failure (2 years) · Patients who have had radiotherapy and who have missing teeth that require replacement with osseointegrated dental implants

It is very uncertain whether hyperbaric oxygen (HBO) therapy changes prosthetic failure compared with no HBO therapy (very low certainty).
