Abstract

The tongue plays an important role in oral functions. Reduced tongue strength is often noted among children with mouth-breathing behaviour. The purposes of this study were to measure the tongue pressure in children with mouth-breathing behaviour, to compare these values to those of children with nasal-breathing behaviour and to analyse the relationship between age and tongue pressure in children with a mouth-breathing pattern and in children with a nasal-breathing pattern. In this cross-sectional analytical observational study, we enroled 40 children aged 5-12 years who either exhibited mouth-breathing behaviour (n = 20) or nasal-breathing behaviour (gender- and age-matched [±2 years] controls; n = 20). Tongue pressure was evaluated using the Iowa Oral Performance Instrument; 3 measurements were recorded for each participant, with a 30-seconds rest interval. The average tongue pressure in the mouth-breathing group was lower than that in the nasal-breathing group. There was no difference in tongue pressure between genders. There was a strong and direct correlation between tongue pressure and age in the nasal-breathing group. The breathing pattern impacts tongue pressure development.
