The aim of the present paper is to investigate the association between advanced stages of periodontitis (Stage III\/IV) and the intensity and duration of sleep bruxism events, measured as bruxism work index (BWI) and bruxism time index (BTI) through surface electromyography.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Subjects were selected from patients regularly attending the School of Dentistry of the University of Siena, Siena, Italy, with the aim of having a test group of patients with periodontitis and a control group without periodontitis. Two calibrated operators performed the periodontal assessment. The sleep\u2010time surface electromyographic activity of the left masseter muscle was registered through a portable device (dia\u2010BRUXO, Biotech\u2010Novations, Sanremo, Italy). Differences between cases and controls in the outcome variables concerning masseter activities were assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>No significant difference was found between the two groups for the sleep bruxism work index and bruxism time index.
