Condition or Disease	Intervention/Treatment	Phase
Bruxism, Sleep Obstructive Sleep Apnea

Outcome Measures

Primary Outcome Measures

Tabulation of polysomnographic report related to sleep efficiency [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 [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) [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.
