Dentoalveolar Malocclusions in Primary and Mixed Dentition in Children with Chronic Mouth Breathing // Зъбно-челюстни деформации във временно и смесено съзъбие при деца със затруднено носово дишане

Difficult nasal breathing is the condition where there is a partial or full, temporary or permanent obstruction of the airway and the processes of inhalation and exhalation are carried out through the mouth. Where there is no morphological or anatomical reason for the occurrence of mouth breathing, it is defined as bad habit. Mouth breathers are those people who breathe through the mouth even during times of rest and relaxation. They should be distinguished from nose breathers who breathe through their mouth during intensive physical activities, but during rest – through their nose. The aim of this dissertation to establish the relationship between the severity of the difficult nasal breathing and the frequency of deviation in the development of the dental arches and the occlusion in children in primary or mixed dentition. From the study of children with difficult nasal breathing, bad habit of staying and sleeping with open mouth; and a control group of nasal breathing children, we can draw the following conclusions: 1. We found that difficult nasal breathing is found in 24.70% оf all the studied children. 2. We found that the main cause of the occurrence of mouth breathing in deciduous dentition is allergic rhinitis (54.50%), in early mixed dentition is the adenoid hypertrophy (40.90%), and in late mixed dentition – it is the bad habit of sleeping with an open mouth (64.70%). 3. We found that in mouth breathing children there is the presence of occlusion class II, overjet and open bite in varying degrees.
