Summary
Orthodontic treatment may affect upper airway space, but the link between decreased dental arch length and airway changes is not definitively proven. Clinicians must carefully manage treatments to avoid potential airway modifications.
Area of Science:
- Orthodontics
- Sleep Medicine
- Craniofacial Development
Background:
- Obstructive sleep apnea syndrome may be linked to reduced upper airway space.
- Understanding the impact of orthodontic treatment on the upper airway is crucial.
Purpose of the Study:
- To review current knowledge on upper airway development and factors causing dental arch length reduction.
- To assess the influence of decreased dental arch length on upper airway development.
Main Methods:
- Literature review on normal upper airway development.
- Analysis of factors leading to dental arch length reduction during orthodontic treatment (e.g., extractions, agenesis, malpositions).
- Investigation of the resulting effects on the upper airway.
Main Results:
- Conflicting findings exist regarding upper airway space reduction after premolar extractions.
- Some studies show no airway space reduction after incisor retraction post-extraction.
- Reduced maxillary diameter and nasal cavity may be associated with missing permanent teeth.
Conclusions:
- Scientific evidence definitively linking decreased dental arch length during orthodontic treatment to upper airway development changes is lacking.
- Vigilance and individualized treatment approaches are necessary to prevent potential upper airway modifications.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
