Introduction:

Sleep disorders can significantly affect the quality of life of children.

Objective:

To determine the frequency of respiratory sleep disorders in children who come to the orthodontic office.

Methods:

To perform this cross-sectional study, section A of the Pediatric Sleep Questionnaire was applied consecutively to parents of children who attended the orthodontic clinic at the Institute of Advanced Dentistry in 2018. For qualitative and quantitative variables measurements , absolute and relative frequency measurements were used with the EPI Info ™ 7 (CDC) program.

Results:

We included 52 patients (28 girls, 24 boys) with an average age of 13 years (PD: 2.23). In the results it was observed that 12 children (23%) presented some type of respiratory disease being the allergy (58.3%) the most reported; and the most commonly used medication (antiallergics, bronchodilators, etc.) in aerosol presentation (40%) and only 4 cases (7.6%) were subjected to some surgery of the respiratory tract, mainly in the adenoids. The snoring was recorded in 30 individuals (57.69%) of whom 18 (58%) belong to the female sex and 13 (42%) to the male sex, without having any association by age or sex. The hours of sleep in the week were on average 9h. (DS = 1.78).

Conclusion:

The high frequency of snoring among the respiratory disorders detected in patients who sought orthodontic treatment in the IOA, indicates that the application of a questionnaire was an adequate tool for the detection of SDB and allows children at risk to be identified and referred to a specialist.
