Oral cyclophosphamide vs prednisone or placebo

Adverse events: hypertension with seizures · idiopathic steroid‐resistant nephrotic syndrome in children

It is very uncertain whether oral cyclophosphamide changes adverse events: hypertension with seizures compared with prednisone or placebo (very low certainty).

Behaviour change / oral health promotion interventions delivered by non-dental professionals and health workers (nurses, midwives, health visitors, community health workers) vs control (no intervention/usual care/isotonic exercise)

Caries experience at the surface level (dmfs/defs) · Children (mean age newborn to ~5.2 years) and their parents/carers

Behaviour change interventions delivered by non-dental health workers produced a small, statistically significant reduction in caries experience at the surface level (dmfs SMD -0.15, 95% CI -0.25 to -0.04; 12 studies); the review judged the overall evidence to be of low quality (not GRADE-rated).

Behaviour change / oral health promotion interventions delivered by non-dental professionals and health workers (nurses, midwives, health visitors, community health workers) vs control (no intervention/usual care/isotonic exercise)

Caries experience · Children (mean age newborn to ~5.2 years) and their parents/carers

Behaviour change interventions delivered by non-dental health workers produced a small-to-moderate, statistically significant reduction in caries experience at the tooth level (dmft SMD -0.34, 95% CI -0.54 to -0.13; 6 studies); the review judged the overall evidence to be of low quality (not GRADE-rated).

Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement) vs usual practice

Dental caries · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

Among children aged 6-8 years, DMFT scores were significantly reduced (SMD -0.11); subgroup not separately GRADE-rated.

Annual increment in DMFS (D3) · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

Oral-health-education interventions significantly reduced net increment in DMFS (SMD -1.05); no significant subgroup difference vs other interventions (P=0.74).

Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement) vs usual practice

Dental caries prevalence measured by dmft or DMFT/S score greater than one · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

School-based interventions may reduce the prevalence of dental caries (RR 0.70, favouring intervention), but the certainty of evidence is very low.
