Aim To ascertain and illustrate specific clinical dento-craniofacial characteristics associated with sleep-disordered breathing (SDB) in non-syndromic children. Methods Narrative review of literature on SDB, dental occlusion and craniofacial morphology retrieved through online literature database search for these terms. The review focused on clinical examples and graphical illustrations in order to ascertain the association between dento-craniofacial characteristics and SDB. Only publications concerning healthy non-syndromic children without any somatic or psychological diagnosis were included. Results Dento-craniofacial characteristics such as anterior open bite, large overjet, cross bite and facial appearance such as convex profile due to mandibular retrognathia and inclination, narrow and high palate can predispose to SDB in non-syndromic children. Furthermore, extended head posture, mouth breathing and general adenoidal face may be symptoms or predisposing factors to SDB in non-syndromic children. Conclusion Dento-craniofacial characteristics as anterior open bite, large overjet due to mandibular retrognathia, cross bite, and narrow and high palate can predispose to SDB in non-syndromic children. Facial characteristics predisposing to SDB can be a convex facial profile, extended head posture, mouth breathing and general adenoidal face. Interdisciplinary collaboration between medical doctors and dentists can prove valuable in diagnostics, prevention and treatment of SDB in non-syndromic children.
