Association Between Obstructive Sleep Apnea and Bruxism

Association Between Obstructive Sleep Apnea and Bruxism: A Retrospective Study

The objective of this retrospective observational study will be to investigate the between the Obstructive Sleep Apnea Syndrome (OSAS) and Sleep Bruxism (SB), in individuals diagnosed through polysomnography (PSG).

Study Overview

• Status: Completed
• Conditions: Obstructive Sleep Apnea; Bruxism, Sleep

Detailed Description

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)".

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Tabulation of polysomnographic report related to sleep efficiency	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.	The deadline is until May 2020 to have all data collected
Tabulation of polysomnographic report related to sleep bruxism	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.	The deadline is until May 2020 to have all data collected
Tabulation of polysomnographic report related to obstructive sleep apnea syndrome (SAOS)	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.	The deadline is until May 2020 to have all data collected
