Oral breathing and dental malocclusions.

摘要: Aim of the present study was to evaluate existing correlations between oral breathing and dental malocclusions. Methods The conducted on a paediatric group 71 breathers selected at Allergology Paediatric Immunology Department Umberto I General Hospital, University Rome "La Sapienza" (Italy). children were based inclusion/exclusion criteria. Children aged 6 12 years with no history craniofacial malformations or orthodontic treatment included. results compared control composed patient nasal breathing. After their medical recorded, all patients underwent orthodontic/otolaryngological clinical examinations. following diagnostic procedures then performed: latero-lateral projection teleradiography, orthopantomogram, impressions, anterior rhinomanometry before after administering local vasoconstrictor, nocturnal home pulse oximetry (NHPO) recording, spirometry test, skin prick cast evaluation cephalometric analysis Tweed's principles. intraoral examination assessed: class type, overbite, overjet, midlines, crossbite, presence parafunctional habits such as atypical swallowing, labial incompetence, finger sucking inner lip. Evaluation casts involved arch perimeter transpalatal width assessment, space analysis. Results showed strong correlation malocclusions, which manifests itself both dentoskeletal functional alterations, leading dysfunctional malocclusive pattern. Conclusion According authors' results, pattern makes it clear that association malocclusions represents self-perpetuating vicious circle in is difficult establish if primary alteration respiratory maxillofacial. Regardless, problem needs be addressed solved through close interaction paediatrician, otorhinolaryngologist, allergologist orthodontist.
