Objective: The goals of this study were to investigate the prevalence of probable bruxism in a group of patients seeking a periodontal care and the association between probable bruxism and periodontal status.
Background: The results of previous studies evaluating the relationship between bruxism and periodontitis are contradictory. In addition, the relationship between probable bruxism and periodontitis in adults has not been evaluated, yet. Therefore, new studies are required in this field to clarify the relationship between bruxism and periodontitis.
Methods: Patients seeking periodontal care at a university periodontology unit were considered in this study. Their periodontal diagnosis, number of missing teeth, presence of probable bruxism, and sociodemographic characteristics were recorded. The periodontal status of each study participant was defined according to the latest consensus of the American Association of Periodontology/European Federation of Periodontology, and the 2018 consensus report on the assessment of bruxism was used to evaluate probable bruxism. A multiple logistic regression analysis was performed to determine the effects of bruxism on periodontitis.
Results: A total of 541 patients (289 females and 252 males, mean age 42.1 ± 15.9 years) were enrolled in the present study. The prevalence of probable bruxism was 36.6%. Additionally, 40.9% of the study population was diagnosed with periodontitis. The probable bruxers were older (P < 0.001), had a higher number of missing teeth (P < 0.001), and had poor periodontal status (P < 0.001). The multivariate logistic regression analysis suggested that probable bruxism was associated with periodontitis, after adjusting relevant factors (odds ratio: 2.243, 95% CI: 1.465-3.434, P < 0.001).
Conclusions: It was observed that the prevalence of probable bruxism was 36.6% and probable bruxers showed higher odds of periodontitis. Future studies with prospective randomized design should be conducted to confirm these results among a larger study population.

Association between waking-state oral behaviors and health, anxiety, and distress in adolescents. A cross-sectional study.

Article Synopsis
- The study investigates the link between non-physiological oral behaviors and awake bruxism (teeth grinding) in adolescents, focusing on their association with mental health issues like depression and anxiety.
- Out of 100 adolescents studied in Medellín, Colombia, 79 completed assessments to measure these behaviors and mental health symptoms using specific questionnaires.
- Findings reveal that while depression isn't a key predictor of non-physiological oral behaviors, anxiety significantly increases the likelihood of both NPAOB and awake bruxism among adolescents.
Validity between signs and symptoms of sleep bruxism against a validated portable electromyographic device.

Background: Sleep bruxism is a major research area in dentistry today and needs valid clinical means of diagnosis against valid instrumental methods. Purpose: To assess the validity of the most commonly reported sleep bruxism (SB) signs and symptoms in the literature against a polysomnography (PSG) validated portable electromyographic (EMG) device (BiteStrip®).
Material And Methods: Fifty young adults (40 women & 10 men, 18-30 years old) volunteered for the sequential and simultaneous administration of the SB signs and symptoms questionnaire versus the BiteStrip®.
Evaluation of craniocervical posture after myofascial pain treatment in adults with bruxism: A randomized clinical trial.

Article Synopsis
- The study aims to examine the effects of botulinum toxin-A and occlusal appliances on craniocervical posture in adults experiencing myofascial pain related to bruxism.
- A total of 60 patients participated, but statistical analysis showed no significant changes in head posture or kyphosis angle after treatment.
- The findings suggest that treating bruxism pain may not improve craniofacial posture, indicating a need for alternative therapies to achieve better posture.
Occlusal splint or botulinum toxin-a for jaw muscle pain treatment in probable sleep bruxism: A randomized controlled trial.
J Dent

Radboud University Medical Center Nijmegen, Department of Dentistry, Nijmegen, the Netherlands. Electronic address:
Article Synopsis
- This study compared the effectiveness of occlusal splints (OS) and botulinum toxin-A (BTX-A) in reducing jaw muscle pain in patients with probable sleep bruxism.
- A total of 59 patients were assessed, showing both treatments significantly reduced pain over time, with no major differences in overall pain reduction between the two.
- However, OS outperformed BTX-A in improving certain jaw mobility parameters and functional outcomes, suggesting possible advantages in specific aspects of treatment for bruxism-related pain.
Genetic polymorphisms and bruxism: A scoping review.

Article Synopsis
- - The study explores bruxism's complex origins, noting that both genetic and non-genetic factors contribute to its development, but the role of genetic markers is still not well understood.
- - Researchers analyzed 21 reports, including 16 original studies, focusing on genetic associations with sleep bruxism (SB) and awake bruxism (AB), identifying 15 significant genetic polymorphisms across 11 genes.
- - Findings suggest specific genes associated with SB (like serotonergic and dopaminergic pathways) and AB (like ACTN3 and ANKK1), indicating potential genetic influences but highlighting the need for further research.
