Clinical examination with 24-month recall vs Clinical examination with 6-month recall

Dental caries · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with 24-month recall showed no clear difference in dental caries: number of tooth surfaces with any caries (ICDAS 1-6) compared with clinical examination with 6-month recall (moderate certainty).

High-volume evacuation (HVE) vs Conventional dental suction (low-volume evacuator / saliva ejector)

Reduction in level of contamination in aerosols (CFU) during ultrasonic scaling at 40 cm from mouth · People undergoing aerosol-generating procedures (AGPs) in a dental setting

It is very uncertain whether high-volume evacuation (HVE) changes reduction in level of contamination in aerosols (CFU) during… compared with conventional dental suction (low-volume evacuator / saliva ejector) (very low certainty).

Clinical examination with 24-month recall vs Clinical examination with 6-month recall

Cost (patient perspective): total cost per patient (GBP) · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with 24-month recall led to lower cost (patient perspective): total cost per patient (GBP) compared with clinical examination with 6-month recall; GRADE not reported.

Younger children's age (3-5 years) vs Older children (>5 years)

Poor oral health-related quality of life (OHRQoL) · Children aged 3-12 years

Children aged 3 years had higher odds of poor OHRQoL than older children (OR 2.00, 95% CI 1.42-2.57; 2 studies; ungraded).
