About this study

The SB and OSAS are sleep disorders with great importance for dentistry. The OSAS is characterized by partial or total obstruction of the upper airways. SB is defined as a repetitive activity of the mandibular musculature characterized by the tightening or grinding of the teeth and/or by the retrusion or propulsion of the mandible. This study retrospective observational will be evaluation to investigate the association between OSAS and SB. Data from PSG and medical records (n=640) will be collected from January 2012 to July 2018 at "Instituto do Sono de Pelotas (ISP)".

Treatment and study plan

Primary outcomes

Tabulation of polysomnographic report related to sleep efficiency

Time frame: The deadline is until May 2020 to have all data collected

These data are provided from the medical report generated in the polysomnography examination in%. Values above 85% will be classified as good sleep efficiency, and values below 85% will be classified as poor sleep efficiency. These polysomnographic exams were performed at the "Sleep Institute of Pelotas (ISP)" from January 2012 to July 2018.
Tabulation of polysomnographic report related to sleep bruxism

Time frame: The deadline is until May 2020 to have all data collected

These data are provided from the medical report generated in the polysomnography examination in the presence or absence of sleep bruxism. These polysomnographic exams were performed at the "Sleep Institute of Pelotas (ISP)" from January 2012 to July 2018.
Tabulation of polysomnographic report related to obstructive sleep apnea syndrome (SAOS)

Time frame: The deadline is until May 2020 to have all data collected

OSAS is classified according to its severity, which varies according to the number of apnea and hypopnea indexes per hour (AHI), 15; moderate of 16-30, and recorded the first upper 31 episodes. These data are provided from the medical report generated in the polysomnography. These polysomnographic exams were performed at the "Sleep Institute of Pelotas (ISP)" from January 2012 to July 2018.
