“…Our overview drew similar conclusions to other recent umbrella reviews regarding the effects of different intervention options for pain reduction in SB. 6,24,25 The benefits of occlusal devices have also been reported, as well as the absence of evidence to recommend any other treatment such as BTX-A, medication, biofeedback and psychological interventions.…”

Bruxism, specifically sleep bruxism (SB), is a worldwide discussed topic in the literature; however, there is insufficient evidence to define and support a standard approach for the treatment of SB. The purpose of this overview was to map the evidence from systematic reviews (SR), examining the effects of interventions to improve chronic pain related to bruxism. The methodological quality of SRs was assessed using the AMSTAR-2 tool. We conducted a comprehensive literature search in April 2020, in the following databases: Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, LILACS, BBO, and Epistemonikos. Nine SRs with critically low to high methodological quality were included. Considering the main findings, botulinum toxin type A (BTX-A) showed a significant pain and sleep bruxism frequency reduction when compared to placebo or conventional treatment (behavioral therapy, occlusal splints, and drugs), after 6 and 12 months. Occlusal splints combined to muscle massage showed some benefit in pain reduction. There was no difference in pain and bruxism frequency between biofeedback therapy and an inactive control group. Regarding drug therapy, there is no difference when amitriptyline, bromocriptine, clonidine, propranolol, and levodopa were compared to placebo. In conclusion, there is some evidence to support the use of occlusal splints plus massage, and BTX-A to reduce chronic pain related to SB. No evidence was provided to support the recommendation of biofeedback therapy and drug therapy. There is still a need for more methodologically rigorous randomized clinical trials (RCT) to be conducted on the efficacy and safety of different therapies for SB.

“…The etiology of this phenomenon is complex and unclear. It is believed that genetic (especially regarding neurotransmitters and arousals), psychological (personality traits, stress sensitivity and anxiety) and exogenous factors (nicotine, caffeine, alcohol and drug use) may play a role in bruxism occurrence and severity [5,21,26].…”

A B S T R AC TSleep bruxism (SB) is a common and complex phenomenon that can result in serious clinical consequences concerning the stomatognathic system including damage to dental hard tissues, especially tooth wear, damage to prosthetic restorations, damage to the periodontium and oral mucosa, and a spectrum of symptoms affecting masticatory muscles. However, there are other conditions with similar clinical manifestations that may resemble or even in some cases mimic SB. The aim of this study was to evaluate the most common sleep-related conditions that can cause clinical implications similar to SB and to emphasize the methods of carrying out a proper differential diagnosis. PubMed, Web of Science, and Scopus databases were searched for current literature on the manifestation of selected sleep disorders in the stomatognathic system. Forty-one articles were finally included in this review. Conditions such as oromandibular myoclonus, dystonia, Parkinson's disease and parkinsonism, epileptic and non-epileptic motor phenomena were included in this review as potentially mimicking the symptoms of sleep bruxism. Included studies indicate that the combination of accurate medical history interview, thorough clinical examination and video-polysomnography seems to be the key to proper differential diagnostics between SB and other medical conditions that can occur during sleep and present similar clinical symptoms affecting the stomatognathic system.

“…A recent systematic review reports that the prevalence of SB in children is between 3.5 and 40.6%, decreasing with age and without gender differences [3]. Also, higher prevalence rates were found in children and adolescents (3-49%) than in adults (1-15%) [4]. Despite the high variability, which could depend on the adoption of parental report strategies to evaluate tooth grinding in children and makes it hard to define an actual prevalence value, the phenomenon is surely of clinical interest.…”

Purpose. A possible relationship between sleep bruxism (SB) and several sleep disorders has been suggested in children, which could influence sleep quality and quality of life. This study aims to assess such correlations in a large sample of school children. Methods. Parents of 741 consecutive children aged between 8 and 12 years filled the Sleep Disturbance Scale for Children (SDSC). It evaluated 45 items grouped in 8 components: duration of night-time sleep, sleep latency, bedtime problems, sleep quality, night awakenings, nocturnal symptoms, morning symptoms, and daytime sleepiness. An item evaluating parental-reported tooth grinding was also included. Correlation analysis was performed between parental-reported tooth grinding and all the other items. Results. A significant correlation between parental-reported tooth grinding and several sleep disorders concerning bedtime problems, night awakenings, nocturnal symptoms, and morning symptoms has been found. In general, correlation strength of significant pairs was low, ranging from 0.092 (sleep apnea) to 0.234 (movement while falling asleep). Conclusions. Parental-reported tooth grinding in children is correlated, even if weakly, with some sleep disorders concerning the sphere of bedtime problems, night awakenings, nocturnal symptoms, breathing symptoms, and morning symptoms. Further studies are needed to confirm these findings, with particular regard to the consistency of correlation outcomes between the parental reports and the sleep laboratory measures.
