Summary
This summary is machine-generated.

Weak evidence suggests Frankel's function regulator-4 (FR-4) with lip-seal training and palatal crib with high-pull chincup can correct anterior open bite in children. Further randomized controlled trials (RCTs) are needed due to potential bias.

Area of Science:

  • Orthodontics and Pediatric Dentistry
  • Evidence-Based Dentistry

Background:

  • Anterior open bite in children requires effective orthodontic or orthopedic interventions.
  • Systematic review of randomized controlled trials (RCTs) to assess treatment efficacy.

Discussion:

  • Limited to three RCTs, with one excluded due to side effects.
  • Two interventions, Frankel's function regulator-4 (FR-4) with lip-seal training and palatal crib with high-pull chincup, showed potential in correcting anterior open bite.
  • Significant methodological limitations including lack of randomization description, sample size calculation, and blinding were noted.

Key Insights:

  • FR-4 with lip-seal training demonstrated a significant effect (RR, 0.02; 95% CI, 0.00-0.38).
  • Palatal crib with high-pull chincup also showed effectiveness (RR, 0.23; 95% CI, 0.11-0.48).

  • Evidence quality is weak, necessitating cautious interpretation.

    • Outlook:

    • Current evidence is insufficient to guide clinical practice for anterior open bite treatment.
    • High-quality RCTs are essential to confirm the efficacy and safety of orthodontic interventions.
    • Further research should focus on robust methodologies to minimize bias and provide reliable data.
