Sleep bruxism (SB) is a common phenomenon defined as a masticatory muscle activity during sleep. Untreated severe SB can have significant dental and orofacial consequences. SB has often been linked with stress and maladaptive coping strategies. Therefore, in this study, a potential correlation between SB, perceived stress and coping strategies was evaluated. A total of 60 adults were enrolled into this study. Participants underwent a detailed intra- and extraoral exam focused on detecting bruxism symptoms. Additionally, the overnight Bruxism Index was recorded using the Bruxoff device. A total of 35 participants with symptoms of bruxism were assigned to the study group, whereas 25 asymptomatic participants were assigned to the control group. The Perceived Stress Scale (PSS-10) was used for stress assessment and Brief-COPE for coping strategies. Results showed that the higher the PSS-10 score, the higher the Bruxism Index was in the study group. Positive coping strategies were chosen most frequently in the control group, while maladaptive ones were chosen in the study group. It can be concluded that there is a relationship between perceived stress and sleep bruxism. Moreover, the type of coping strategies used by participants may have an impact on sleep bruxism, but the relationship should be further investigated.

Sleep bruxism (SB) is a masticatory muscle activity during sleep and a common phenomenon. Severe SB can have a serious impact on the success of dental treatment. Reliable methods of screening and diagnosing patients with SB are crucial. Therefore, in this study, a Bruxoff device as a potential screening and diagnostic method for sleep bruxism was evaluated. A total of 60 adults participated in this study: 35 patients with symptoms of bruxism (study group) and 25 asymptomatic patients (control group). Data were recorded using Bruxoff. All symptomatic patients participating in the study turned out to be bruxers, while not all asymptomatic patients turned out to be non-bruxers according to the Bruxoff device. Bruxoff is a simple screening device that can be safely used to evaluate masseter muscle activity during sleep. Since the device does not have a built-in microphone and/or video camera and, therefore, cannot record grinding sounds, the objective capabilities of Bruxoff as a single diagnostic device for sleep bruxism are limited.

Bruxism is one of the least known dysfunctions of the stomatognathic system. Bruxism decreases significantly the rate of success not only in a perspective prosthetic treatment, but also in restorative dentistry, periodontics or even surgical procedures. Presently, theories pertaining to bruxism evolve around the impulses coming from the central nervous system, which in turn cause a temporary nocturnal tachycardia, followed by a bilateral contraction of the masseter muscles. However, the multifactoral and complex aetiology of bruxism still requires further consideration and research.

Bruxism is referred to as grinding and clenching of the teeth. It is a disorder affecting an increasing number of patients. This disease causes severe ailments that negatively influencing the daily functioning and manifesting, among the others, as toothaches, masticatory muscle pain, headaches, and tooth hypersensitivity. The aim of the work is to analyse the contemporary treatment methods and methods of alleviating the effects of the disease. In addition, it evaluates the usefulness of these methods in daily dental practice. The article shows the contemporary view of treatment, including the multidisciplinary approach. The authors present treatment methods of bruxism, such as: splints, physiotherapy, psychotherapy, biofeedback, and pharmacological treatment. The variety of methods currently used and the lack of clear guidelines for treatment of bruxism should be emphasised. The article also draws attention to the need to modify the daily behaviour of the patient through relaxation exercises or biofeedback, in order to eliminate bruxism and not just alleviate its symptoms. A multidirectional approach and treatment of bruxism can produce satisfactory and lasting results.
