Consumption of xylitol chewing gum by women (mothers) vs no intervention

Change in Mutans streptococci (MS) count in saliva · healthy people

Xylitol significantly reduced Mutans streptococci in saliva compared with no intervention (SMD -1.47, 95% CI -1.94 to -0.99; 3 trials), though heterogeneity was very high (I2=98%); not GRADE-rated.

PDHA program with robust prevention vs PDHA program or PDHA program with intensive staffing

Tooth decay-free children · Alaska children aged 5 to 18 years

The robust prevention PDHA model was projected to yield more than 50% tooth decay-free children versus 8% with other PDHA models, without a GRADE rating.

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).

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

Projected proportion of caries-free children (5-18 years) · Alaska Native children (below age 18)

A simulation projected 0% of children aged 5-18 would be caries-free under the baseline scenario (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).
