Introduction: Sleep bruxism (SB) presents as repetitive bracing or thrusting movements of the mandible, encompassing teeth clenching or grinding, which affects oral health. Obstructive sleep apnea (OSA) is a respiratory disorder during which total or partial airway obstructions appear during sleep, leading to arousals in response to respiratory effort. In the highly prevalent nowadays obstructive sleep apnea syndrome (OSAS) patients suffer from repeated airway collapses. This can cause various disorders: daytime sleepiness and drowsiness, cognitive disorders, problems with the cardiovascular and metabolic systems.Aim: The present study aims to investigate the influence of SB and OSAS on dental health.Materials and Methods: For the period January 2020–March 2021, in the available databases (PubMed, BioMedCentral, ScienceDirect, Scopus, Web of Science), a systematic analysis of scientific publications has been conducted examining the influence of SB and OSAS on dental health.Results: Obstructive sleep apnea syndrome is a clinical risk factor for SB. It can lead to tooth attrition and abrasion, fractures, hypersensitivity, periodontal diseases, dysfunction in the temporomandibular joint or muscles of mastication (including hypertrophy), headaches and poor quality of sleep. Malocclusions are connected to SB. Authors report that symptoms of apnea and clenching are more frequent in OSAS patients.Conclusion: Obstructive sleep apnea syndrome and SB lead to dental health problems, which are encountered in the dental office
