Missing teeth and pediatric obstructive sleep apnea.

Area of Science:

• Pediatric Dentistry
• Sleep Medicine
• Orthodontics

Background:

• Missing teeth in early childhood can alter facial development and narrow the upper airway.
• The study investigates the link between dental agenesis/early extractions and obstructive sleep apnea (OSA).

Purpose of the Study:

• To explore the association between missing teeth (dental agenesis or early extraction) and obstructive sleep apnea (OSA) in children.
• To compare children with missing teeth to those with tonsilloadenoid hypertrophy and OSA symptoms.

Main Methods:

• Reviewed clinical data, polysomnographic sleep studies, and orthodontic imaging for children with dental agenesis (32) or early tooth extraction (11).
• Compared findings to a control group (64) with normal teeth but tonsilloadenoid hypertrophy and OSA symptoms.

Main Results:

• Children with missing teeth (n=43) exhibited clinical signs suggestive of OSA.
• A significant difference in apnea-hypopnea indices (AHI) was observed across groups (p < 0.001).
• In children with missing teeth, increasing age correlated with higher AHI (R²=0.71, p < 0.0001).

Conclusions:

• Congenital dental agenesis or early tooth extraction can lead to a smaller oral cavity, increasing OSA risk.
• OSA in these children may be diagnosed later due to subtle initial symptoms, potentially worsening over time.
• Isolated dental agenesis, not part of a syndrome, was observed in the study group.
