Study summary

Correlation Between Posterior Crossbite and Risk of Obstructive Sleep Apnea

Read the detailed description

Understanding the correlation between posterior crossbite and OSA risk is essential for early detection and prevention. Pediatric dentists and orthodontists are uniquely positioned to identify craniofacial risk factors and initiate early intervention.

Screening tools such as OSA-18 can help identify children at risk and facilitate timely referral for multidisciplinary management. Furthermore, evaluating this association will contribute to improving clinical decision-making and patient outcomes.

Aim of study:

To assess the correlation between posterior crossbite and the risk of obstructive sleep apnea in children using the OSA-18 questionnaire.
