The recent hypothesis on the etiology of SB supports the role of the central and autonomic nervous systems. Therefore, in this study, we aimed to assess the intensity of SB in patients with arterial hypertension. A total of 70 adults participated in this study: 35 patients with hypertension (study group) and 35 normotensive subjects (control group). Data were recorded using home portable cardiorespiratory polygraphy. The bruxism episode index (BEI) in the study group was found to be significantly higher compared to the control group (3.4 \u00b1 3.25 vs. 2.35 \u00b1 2.29, p = 0.04). Hypertension, higher body mass index (BMI), lower values of mean oxygen saturation (SpO2), and a higher percentage of SpO2 &lt; 90% constituted independent risk factors for increased BEI. These results suggest the need for special oral care in hypertensive patients, patients with higher BMI, lower values of SpO2 and a higher percentage of SpO2 &lt; 90%.<\/jats:p>","DOI":"10.3390\/jcm7100327","type":"journal-article","created":{"date-parts":[[2018,10,5]],"date-time":"2018-10-05T12:16:44Z","timestamp":1538741804000},"page":"327","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Evaluation of Intensity of Sleep Bruxism in Arterial Hypertension"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1283-8460","authenticated-orcid":false,"given":"Helena","family":"Martynowicz","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, 213 Borowska St., 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawel","family":"Dymczyk","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, 213 Borowska St., 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8943-0549","authenticated-orcid":false,"given":"Marzena","family":"Dominiak","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Wroclaw Medical University, 26 Krakowska St., 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Klaudia","family":"Kazubowska","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Wroclaw Medical University, 26 Krakowska St., 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Skomro","sequence":"additional","affiliation":[{"name":"Division of Respiratory, Critical Care and Sleep Medicine, University of Saskatchewan, 107 Wiggins Road, SK S7N 5E5 Saskatoon, Saskatchewan, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafal","family":"Poreba","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, 213 Borowska St., 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8366-0239","authenticated-orcid":false,"given":"Pawe\u0142","family":"Gac","sequence":"additional","affiliation":[{"name":"Department of Hygiene, Wroclaw Medical University, 7 Mikulicza-Radeckiego St., 50-345 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Wojakowska","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, 213 Borowska St., 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grzegorz","family":"Mazur","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, 213 Borowska St., 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4953-7143","authenticated-orcid":false,"given":"Mieszko","family":"Wieckiewicz","sequence":"additional","affiliation":[{"name":"Department of Experimental Dentistry, Wroclaw Medical University, 26 Krakowska St., 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,5]]},"reference":[{"key":"ref_1","unstructured":"American Academy of Sleep Medicine (2014).
