Results of nose breathing evaluation during orthodontic treatment in children

Abstract

Relevance. In the modern practice of an orthodontist, distal occlusion caused by respiratory dysfunction is increasingly more common. It is especially evident in early mixed dentition, i.e., in 6-8-year-old children with diagnosed pathology of ENT organs, namely, adenoids.Objective. The study aimed to evaluate the relationship between respiratory dysfunction and distal occlusion in children with early mixed dentition.Materials and methods. The study performed conventional anterior and posterior rhinoscopy, endoscopic examination of ENT organs, anterior active rhinomanometry, and masticatory muscles’ electromyography. The orthodontic examination included an oral examination, impression-taking, occlusion assessment, morphometric analysis of the jaw models and lateral cephalometric image measurements.Conclusion. In modern medical practice, the pathology of ENT organs and maxillofacial anomalies are closely related. Therefore, the collaboration between an orthodontist and an ENT specialist is the key to the effective treatment of distal occlusion in early mixed dentition.
