Study population: 200 children, 100 previously diagnosed with oronasal breath (51 females and 49 males) who participated in the study group and 100 nasal breathers (54 females and 46 males) which were the control group.

Brief summary: Purpose: To examine whether nasal breathing influences the perception of sound causing trade between hard and soft consonants in the writing of children in school age and the incidence of trade.

Detailed description: To achieve the above goal explained, it was used:

Methods: The sample was consisted of 200 children, 100 previously diagnosed with oronasal breath (51 females and 49 males) who participated in the study group and 100 nasal breathers (54 females and 46 males) which were the control group. 36 words were dictated as minimal pairs to be written. Then a story was submitted in sequence of six figures from which the subjects produced a text.
