Background: Bruxism is a multifactorial biopsychosocial condition involving repetitive jaw muscle activity, influenced by psychological stress, anxiety, and maladaptive coping strategies. Methods: In this cross-sectional observational study, 111 health sciences students (mean age 22.29 ± 3.10 years; 66.6% women) underwent standardized DC/TMD clinical evaluation and completed the GAD-7, COPE Inventory, and a 105-item Stroop Test. Results: Bruxism prevalence was 63.96% (71/111). Students with bruxism had higher GAD-7 scores (10.63 ± 5.78 vs. 5.80 ± 3.66; mean difference 4.83, 95% CI 2.88–6.78; p < 0.001, g = 0.94), with clinically relevant anxiety nearly three times more frequent (55.4% vs. 19.6%; RR = 2.83, 95% CI 1.68–4.76). Stroop interference times were slower in the bruxism group (42.19 ± 16.87 s vs. 34.57 ± 16.25 s; mean difference 7.63 s, 95% CI 0.90–14.35; p = 0.027, g = 0.46), though accuracy was similar. COPE results showed a shift toward emotion-focused and avoidance strategies with increasing muscle pain. Conclusions: Bruxism is strongly linked to elevated anxiety, maladaptive coping strategies, and reduced inhibitory control speed. Integrating psychological screening tools such as GAD-7 and COPE into dental and medical practice could enable early identification and referral, supporting comprehensive management that combines dental treatment with psychological interventions to prevent chronic pain and long-term complications.

Awake Bruxism (AB) is defined as masticatory muscle activity during wakefulness, characterized by repetitive or sustained tooth contact and/or the bracing or thrusting of the mandible. AB remains less understood than Sleep Bruxism (SB), and its identification remains a methodological challenge. The aim of this study was to introduce the Awake Bruxism Identification Tool (ABIT), developed for children and adolescents aged 8 to 12 years, to facilitate the identification of AB. The tool integrates data from self-reports, clinical examinations, and the Ecological Momentary Assessment (EMA). It comprises questionnaires using a five-point Likert scale, an analog EMA component involving color-based responses, and a clinical inspection. The tool adopts the concept of an “AB Spectrum”, as it generates individualized scores based on the combined outcomes of these multiple assessment components. The ABIT was piloted with ten families to evaluate its comprehensibility, applicability, and reliability. The results demonstrated that the participants found the questions understandable, that the tool had a minimal impact on daily family routines, and that it required approximately 5–10 min to complete. Additionally, the test–retest reliability indicated temporal stability. In terms of identification, four children were classified within the “AB identified by report and self-report,” while three were identified through the “report, self-report, and EMA.” Based on participant feedback, adjustments were made to the instrument, including the addition of an item addressing Sleep Bruxism. Although the ABIT is being applied for the first time in a research setting, it presents a promising, clinically relevant approach grounded in the self-perception of children and their caregivers.

Introduction: Sleep is a fundamental biological function critical for physical and mental health. Chronic sleep disturbances can significantly impair cognitive, emotional, and social functioning, leading to deficits in attention, alertness, and executive function, alongside increased irritability, anxiety, and depression. For pediatric patients, such disturbances pose additional concerns, potentially disrupting developmental processes and quality of life for both children and their families. Objectives: Emerging evidence suggests a correlation between neurofibromatosis type 1 (NF1) and an increased prevalence of sleep disorders in children. NF1, a genetic condition affecting multiple body systems, including the nervous system, may predispose children to sleep disturbances due to its neurodevelopmental and behavioral impacts. This observational case–control study aimed to explore the association between NF1 and sleep disorders in pediatric patients, comparing the prevalence and patterns of sleep disturbances between NF1 patients and healthy controls. Patients and Methods: The study included 100 children aged 2–12 years, divided into two groups: 50 with NF1 (case group) and 50 children belonging to the control group. NF1 patients were recruited from the Unit of Rare Diseases of the Nervous System in Childhood at the Policlinico “G. Rodolico—San Marco” University Hospital in Catania. Data were collected using a questionnaire completed by parents, assessing parasomnias, breathing-related sleep disorders, and other behavioral and physiological disturbances; these data were compared to a sleep assessment performed using an Apple Watch Ultra. Results: NF1 patients exhibited a significantly higher prevalence of sleep disorders than controls. Notable differences included increased nocturnal hyperhidrosis (48% vs. 10%), bruxism (48% vs. 28%), restless legs syndrome (22% vs. 4%), frequent nighttime awakenings (22% vs. 8%), and sleep paralysis (12% vs. 0%). A finding of poorer sleep quality also emerged from the results of sleep analysis using an Apple Watch Ultra. Conclusions: These findings confirm an elevated risk of sleep disorders in children with NF1, emphasizing the importance of early identification and management to improve quality of life and mitigate cognitive and behavioral impacts. Further research is essential to understand the mechanisms underlying these associations and develop targeted interventions for this population. Full article

Background: Obstructive sleep apnea (OSA) is a prevalent sleep disorder characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep. While the systemic implications of OSA are well documented, the dental consequences are less frequently discussed yet equally significant. This review aims to elucidate the oral health impacts of OSA, emphasizing the importance of interdisciplinary care. Methods: A comprehensive literature search was conducted across several databases to identify studies examining the relationship between OSA and various oral health parameters. The review included observational studies, clinical trials, and systematic reviews published in English up to January 2024. Results: OSA was significantly associated with heightened risks of bruxism, dry mouth, periodontal disease, temporomandibular joint disorders, palatal and dental changes, and alterations in taste sensation. Mouth breathing associated with OSA was a critical factor in exacerbating xerostomia and dental caries. Furthermore, the systemic inflammation induced by OSA appeared to correlate with the severity of periodontal disease. Patients using oral appliance therapy for OSA also showed notable changes in dental occlusion and required ongoing dental monitoring. Conclusions: The findings underscore the bidirectional relationship between OSA and oral health, highlighting the need for dental professionals to be integral participants in the management of OSA. Early dental evaluation and intervention can contribute to the overall health and quality of life of individuals with OSA. The review advocates for the development of clinical guidelines to facilitate the early identification and management of OSA-related oral health issues within dental practice and encourages a collaborative approach to patient care.

Intraoral devices for bite-force sensing have several applications in odontology and maxillofacial surgery, as bite-force measurements provide additional information to help understand the characteristics of bruxism disorders and can also be of help for the evaluation of post-surgical evolution and for comparison of alternative treatments. A new system for measuring human bite forces is proposed in this work. This system has future applications for the monitoring of bruxism events and as a complement for its conventional diagnosis. Bruxism is a pathology consisting of grinding or tight clenching of the upper and lower teeth, which leads to several problems such as lesions to the teeth, headaches, orofacial pain and important disorders of the temporomandibular joint. The prototype uses a magnetic field communication scheme similar to low-frequency radio frequency identification (RFID) technology (NFC). The reader generates a low-frequency magnetic field that is used as the information carrier and powers the sensor. The system is notable because it uses an intra-mouth passive sensor and an external interrogator, which remotely records and processes information regarding a patient’s dental activity. This permits a quantitative assessment of bite-force, without requiring intra-mouth batteries, and can provide supplementary information to polysomnographic recordings, current most adequate early diagnostic method, so as to initiate corrective actions before irreversible dental wear appears. In addition to describing the system’s operational principles and the manufacture of personalized prototypes, this report will also demonstrate the feasibility of the system and results from the first in vitro and in vivo trials.
