White spot lesion formation (QLF: fluorescence loss, lesion area) · Orthodontic patients of any age with fixed braces (new DLs assessed at debond)
Indirect bonding with a flowable adhesive favored less QLF-measured demineralization, with certainty not graded.
1 finding from 1 review
The DB group exhibited significantly higher loss of fluorescence and degree of demineralization compared to the IB group between T0 and T1, with notable differences in specific quadrants (p <0.05 for ΔF and ΔF max).

Lightness/brightness change of white spot lesion (luminosity L*, T0 to T1) · Patients with post-orthodontic white spot lesions and permanent dentition
ICON resin infiltration showed no statistically significant change in lightness/brightness of post-orthodontic white spot lesions at 6 months (pooled Cohen's d/SMD -0.001, 95% CI -0.23 to 0.23; 3 studies, 330 teeth; I2=97%); not GRADE-rated.

Color change of white spot lesion (color difference, T0 to T1) · Patients with post-orthodontic white spot lesions and permanent dentition
ICON resin infiltration significantly improved the color of post-orthodontic white spot lesions at 6 months (pooled Cohen's d/SMD 1.36, 95% CI 1.14 to 1.59; 4 studies, 458 teeth), although heterogeneity was very high (I2=98%) with a heavy outlier (Kannan); not GRADE-rated.

Salivary flow rate (stimulated) · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population
Stimulated salivary flow rate was significantly lower in anorexia nervosa patients than controls, but only unstimulated flow was meta-analyzed; this outcome is ungraded.

Salivary flow rate (unstimulated) · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population
Anorexia nervosa probably reduces unstimulated salivary flow rate versus healthy controls (MD -0.27 ml/min, 95% CI -0.31 to -0.24; moderate certainty).
