Purpose: This narrative review aims to elucidate the anatomical features of sleep‐disordered breathing (SDB) in children. By identifying key structures and intervening proactively, we seek to alter craniofacial growth patterns and improve functional outcomes for SDB children.Methods: The literature on pediatric sleep‐disordered breathing (PSDB), pediatric obstructive sleep apnea (OSA), anatomical predispositions, and the relationship between skeletal deformity and PSDB was examined using PubMed and Google Scholar databases, covering studies from 2006 to 2024.Results: Forty relevant articles were reviewed, focusing on craniofacial characteristics associated with PSDB. The etiology of PSDB is multifactorial, with adenoid and palatal tonsil enlargement being the most common cause. While adenotonsillectomy is recommended as the primary treatment, residual SDB may result in craniofacial skeletal deformities contributing to upper airway constriction. Typical craniofacial phenotypes of SDB include excessive vertical growth and constriction of the maxilla, a retruded mandible, and posterior rotation, known as a Class II hyperdivergent pattern. Conversely, Class III with an underdeveloped maxilla shows a relatively lower risk for SDB due to reduced nasal cavity and nasopharyngeal airway volumes. Transverse maxillary constriction with a high, deep palatal vault is a significant risk factor. Additionally, nasal obstruction and low tongue posture, with or without a short lingual frenulum, are identified as craniofacial risk factors for SDB development in children.Conclusion: Early diagnosis and intervention are critical in managing PSDB. Dentists, through screening and early treatment, can significantly influence craniofacial growth and health outcomes. A multidisciplinary approach is essential for effective management, improving the quality of life and long‐term health of affected children.

The aim of this preliminary study was to evaluate the short-term changes of occlusal contacts and muscle activity after orthodontic treatment during the use of a multi-layer clear retainer. Evaluation was done with the T-scan and BioEMG systems. A total of 18 subjects were included, who were evaluated at three time intervals—T0 at debonding, T1 at one month after retainer delivery, and T2 at four months after retainer delivery. The T-scan and electromyography (EMG) data were recorded simultaneously. The T-scan system recorded the occlusion time, disclusion time and force distribution. The EMG waves were quantified by calculating the asymmetry index and activity index. The time variables changed but not significantly. Occlusal force decreased in the anterior dentition and increased in the posterior dentition during T0–T2. There was no clear evidence of a relationship between unbalanced occlusal forces and muscle activity. In most subjects, the temporalis anterior muscle was more dominant than the masseter muscle. From this preliminary computerized study, there were no significant changes in the state of the occlusion or muscle activity during the short-term retention period.
