Brief Summary

This observational cross-sectional study evaluated the impact of sagittal skeletal malocclusions on sleep quality in children without orofacial functional disorders. A total of 164 children aged 7-13 years were assessed. Sleep quality was measured using the Children's Sleep Habits Questionnaire (CSHQ), and participants were classified as skeletal Class I, II, or III based on cephalometric analyses. Comparisons were made between skeletal groups regarding CSHQ scores, mandibular and vertical skeletal measurements, and upper airway dimensions. The aim was to determine whether skeletal discrepancies independently influence pediatric sleep quality in the absence of functional impairments.

Outcome Measures

Primary Outcomes (1)

• Sleep Quality (CSHQ Score)

  Sleep quality was assessed using the Children's Sleep Habits Questionnaire (CSHQ), a validated parent-reported tool. Higher total scores indicate poorer sleep quality.

  At baseline (single assessment)

Study Arms (3)

Group 1: Skeletal Class I

Participants with skeletal Class I malocclusion based on ANB angle.

Other: Observational assessment

Group 2: Skeletal Class II

Participants with skeletal Class II malocclusion based on ANB angle.

Other: Observational assessment

Group 3: Skeletal Class III

Participants with skeletal Class III malocclusion based on ANB angle.

Other: Observational assessment

Interventions

Observational assessment OTHER

Evaluation of sleep quality using the Children's Sleep Habits Questionnaire (CSHQ) and cephalometric analysis of mandibular position (SNB), vertical dimensions (SNGoGn, FMA), and upper airway measurements. No active intervention was performed.

Group 1: Skeletal Class I; Group 2: Skeletal Class II; Group 3: Skeletal Class III

Study Population

The study population consisted of children aged 7-13 years presenting with skeletal Class I, II, or III malocclusion. Only patients without systemic diseases, orofacial functional disorders, previous orthodontic treatment, or craniofacial anomalies were included

You may qualify if:

• Children aged 7-13 years
• Presence of skeletal Class I, II, or III malocclusion (based on ANB angle)
• Written informed parental consent

You may not qualify if:

• Presence of systemic diseases
• Current use of medications such as anticonvulsants, immunosuppressants, or calcium channel blockers
• Exposure to stressful life events within the past month
• Presence of deleterious oral habits (e.g., thumb sucking, mouth breathing, infantile swallowing)
• Signs of tonsillar hypertrophy, nasal deviation, nasal polyps, or adenoid vegetation
• Diagnosis of sleep-disordered breathing (SDB)
• History of orofacial surgery or orthodontic treatment
• Presence of craniofacial anomalies (e.g., cleft lip/palate, syndromes)
