This cross-sectional study was conducted to assess i) the prevalence of probable bruxism ii) the association between probable bruxism and periodontal status.The age, gender, education level, tooth loss, presence of probable bruxism and periodontal status of patients were evaluated. Periodontal statuses of the participants were defined according to the American Association of Periodontology/European Federation of Periodontology, 2017 consensus and assessment of probable bruxism was performed according to the 2018 consensus report on the assessment of bruxism.

This cross-sectional study was conducted to assess i) the prevalence of probable bruxism ii) the association between probable bruxism and periodontal status dental examination, all participants completed a standardized questionnaire. Sociodemographic findings comprised age, gender and educational level. Periodontal statuses of the participants were defined according to the American Association of Periodontology/European Federation of Periodontology, 2017 consensus. Participants were diagnosed with periodontitis if interdental clinical attachment loss (AL) was detected at ≥2 non-adjacent teeth, or buccal or oral AL was ≥3 mm with probing depth >3 mm was detected at ≥2 teeth. 12 In addition number of missing teeth is recorded.Assessment of probable bruxism was performed according to the 2018 consensus report on the assessment of bruxism.Presence of masticatory muscle hypertrophy, temporomandibular joint pain, indentations on the tongue or lip and/or a linea alba on the inner cheek, damage to the dental hard tissues (eg, cracked teeth), mechanical wear of the teeth (ie, attrition), repetive failures of restorative work/prosthodontics constructions were examined in clinical evaluation.
