Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Review question
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | Trials that recruited participants (80% aged <= 16 years) receiving orthodontic treatment to correct deep bite and retroclined upper front teeth. Excluded trials of participants with a cleft lip or palate, or both, or other craniofacial deformity/syndrome, and trials in which participants had received surgical treatment for their Class II malocclusion. | None (no eligible studies included) |
| Intervention | Active interventions: orthodontic braces (removable, fixed, functional) or head braces with or without extraction of permanent teeth. | None (no eligible studies included) |
| Comparison | No treatment or delayed treatment (for objective 1); orthodontic treatment involving extraction of permanent teeth (comparator for objective 2). | None (no eligible studies included) |
| Outcomes | Primary: dento-occlusal results of treatment, measured with the PAR index. Secondary: number of visits required to complete treatment and the duration of treatment (for objective 2); cephalometric measurements (ANB change and front teeth inclination changes); participant discomfort; gingival and TMJ symptoms; side effects; quality of life. | None (no eligible studies included) |
| Study designs | Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) | None (no eligible studies included) |
| Timing | Where appropriate, outcome data were to be grouped into those measured post-phase I (growth modification phase) and post-phase II (fixed brace phase), with post-retention outcomes recorded where available. | None (no eligible studies included) |
