Background: Clinically, data on the association of early-life secondhand smoke (SHS) exposure with sleep bruxism and dental problems are scarce.

Objective: To examine whether the relationship between early-life SHS exposure with sleep problems, sleep bruxism, and dental problems in children.

Methods: Within the scope of this study, questionnaires were applied to the volunteer parents of 710 children, aged 5-12 years old. The questionnaire applied in this study named as Children's Sleep Habits Questionnaire (CSHQ) and consists of seven subscales and a total of 33 items. The questionnaire was completed retrospectively by any parent, and the presence of sleep bruxism was questioned during the anamnesis. Afterward, the presence of dental decay and tooth wear was evaluated during intraoral and radiographic examinations. Dental decay and tooth wear were scored with the DMFT/deft index and tooth wear index of Smith & Knight, respectively.

Results: The presence of sleep bruxism was significantly higher in children with parasomnia (p = 0.01; p < 0.05). The presence of tooth wear in children with sleep bruxism was found to be statistically significant (p = 0.032; p < 0.05). It was observed that the presence of sleep bruxism was higher in the children of individuals who smoked at home (p = 0.027; p < 0.05).

Conclusion: Sleep bruxism, untreated dental decay and exposure to early-life secondhand smoke may have a negative impact on children's sleep habits and characteristics.

Background: Intra-oesophageal acid stimulation increases masseter muscle activity. However, the infusion speeds used in previous studies are significantly slow, with minimal acid volume (30 mL over 30 min). Additionally, it is unclear how masseter muscle activity, symptoms of discomfort, stress levels and saliva quantity change over time.

Objectives: The time course of masseter muscle activity, heartburn and discomfort symptoms, salivary cortisol concentration to assess stress, autonomic nervous system (ANS) activity and saliva quantity under the influence of intra-oesophageal acid infusion were evaluated at a faster injection rate and larger volume than in previous studies.

Methods: Ten healthy adults underwent polygraphic monitoring, consisting of electromyography of the masseter muscle and electrocardiography during intra-oesophageal acid infusion (10 mL/min, 10 min). Symptoms of heartburn and discomfort were assessed using the visual analogue scale (VAS), and saliva quantity was measured. Friedman's test was used for multiple comparisons.

Results: Masseter muscle activity, VAS scores for heartburn and discomfort, as well as saliva quantity during the 10-min acid infusion, increased significantly compared with that before acid infusion (p < 0.001, 0.001, 0.019 and 0.047, respectively) and decreased 10 and 20 min after acid infusion (p = 0.004, 0.004 and 0.007, respectively). No significant changes were observed in the salivary cortisol concentration or ANS activity.

Conclusion: Intra-oesophageal acid infusion stimulated symptoms of heartburn and discomfort and increased masseter muscle activity and saliva production, which may not be related to psychological stress.

Objectives: To analyse temporomandibular disorders (TMD), bruxism and well-being in patients with fibromyalgia and compare these outcomes with a control group.

Method: Diagnostic criteria for the assessment of TMD, bruxism and well-being were used in a clinic context including patients with fibromyalgia (n = 71) and a control group of healthy subjects (n = 151). Participants completed an online questionnaire measuring temporomandibular pain, headache attributed to TMD, jaw locking, joint sounds, headache to bruxism, potential sleep bruxism, potential awake bruxism, jaw functional limitation scale 8 (JFLS-8), generalised anxiety disorder scale 7, oral health impact profile scale 14, World Health Organization well-being index (WHO-5) and Pittsburgh sleep quality index (PSQI).

Results: TMD and bruxism were significantly associated with the type of population (χ² = 8.77-57.62; p < 0.05; ES = 0.20-0.51). Fibromyalgia patients showed higher prevalence (% values) than control group in temporomandibular pain, headache attributed to TMD, jaw locking, headache attributed to potential bruxism, sleep bruxism and awake bruxism. However, there was a greater prevalence of joint sounds in the control group compared to the fibromyalgia group. Also, fibromyalgia patients scored significantly higher (p < 0.001) on JFLS-8, GAD-7, OHIP-14 and PSQI with a large effect size (ES = 0.51-0.73), while WHO-5 scores were significantly lower (ES = 0.58).

Conclusion: Patients with fibromyalgia had greater prevalence than the control group in TMJ pain, headache attributed to TMD, jaw locking, headache attributed to bruxism, sleep bruxism and awake bruxism. Another main finding was that patients with fibromyalgia had greater jaw functional limitation, generalised anxiety and impact of oral health on an individual's life. In addition, fibromyalgia patients showed lower sleep quality and well-being index.

Objective: The aim of this investigation was to compare the self-reported frequency of awake bruxism (AB) behaviours by means of a validated single-observation point questionnaire (i.e., Oral Behaviour Checklist [OBC]) with the frequency reported in real-time with an Ecological Momentary Assessment (EMA) over 1 week.

Materials and methods: One hundred healthy young adults took part in the study. The frequency of some activities belonging to the spectrum of AB behaviours (i.e., teeth contact, mandible bracing, teeth clenching, teeth grinding) was evaluated using the EMA approach with smartphone technology support over 1 week. The OBC questionnaire was used to evaluate the self-reported frequency of the same AB behaviours. Spearman's rank correlation coefficient was adopted to test the correlation between the average score of each OBC question considered (i.e., teeth contact, mandible bracing, teeth clenching, teeth grinding) and the average frequency of the corresponding EMA item.

Results: Statistical analysis showed a weak-to-moderate level of correlation between the two different AB assessment methods. Mandible bracing showed the highest level of correlation, while teeth grinding had the lowest one.

Conclusions: While the OBC represents a valid and easy-to-administer screening tool for evaluating bruxism behaviours, the EMA approach provides a more detailed real-time report on AB behaviours.

Background: Current research relates jaw clenching to athletic performance, in terms of force and agility. However, the impact of jaw clenching on sports accuracy is unclear.

Objectives: To analyse the impact of jaw position and chewing type on free-throw accuracy and electromyographic (EMG) activity of masticatory muscles during free-throws.

Methods: Cross-sectional study with 25 female basketball players aged 18-44. Each participant executed 18 free-throws under three different jaw conditions: mandibular rest, maximum intercuspation, and with interdental cotton rolls, in randomised order.

Results: Chewing type and jaw position were not associated with shooting accuracy (p = 0.106; p = 0.778). There was a positive correlation between EMG activity of the right masseter and free-throw accuracy at maximum intercuspation (r_s = 0.402; p = 0.046). In contrast, negative correlations were found with other muscles when the occlusal vertical dimension was altered (r_s = -0.619, p = 0.001; r_s = -0.490; p = 0.013; r_s = -0.534; p = 0.006). The chewing type affected the EMG of the left masseter in the altered occlusal vertical dimension (H = 6.969; p = 0.031). Significant differences in EMG recordings were observed across different mandibular positions during free-throws (p < 0.001).

Conclusions: While jaw positioning and chewing type do not impact free-throw accuracy in amateur female basketball players, the EMG activity of masticatory muscles is linked to shooting performance. This highlights the need for further research on motor behaviour of masticatory muscles in precision sports, especially for athletes using intraoral devices.

Background: Post-stroke dysphagia can lead to serious complications and appropriate rehabilitation can significantly improve swallowing function. However, the best rehabilitation method for post-stroke dysphagia patients is not clear at the present stage, so it is necessary to conduct a comprehensive network meta-analysis and systematic review of different interventions for dysphagia.

Objective: To compare the effectiveness and ranking of different interventions for improving swallowing function, and feeding and daily function in patients with post-stroke dysphagia.

Methods: Seven databases were searched from the date of inception to September 1, 2022. Two investigators independently conducted literature searches, selected randomized controlled trials on dysphagia interventions, and assessed study quality. Network meta-analysis was conducted by using Stata software.

Results: A total of 33 studies involving 1,341 patients were included. According to the ranking probabilities, acupuncture was rated as the most effective of all interventions to enhance patients' swallowing function (surface under cumulative ranking curve values [SUCRCV]: 99.0%, standardized mean difference [SMD]: -2.40, 95% confidence interval [CI]: -3.38 to -1.43), followed by the chin tuck against resistance exercise (CTAR, SUCRA: 89.9%, SMD: -1.83, 95% CI: -2.69 to -0.97). Among all the interventions, acupuncture was the most effective for feeding and daily function (SUCRCV: 88.4%, SMD: -1.62, 95% CI: -2.94 to -0.30).

Conclusions: The results showed that acupuncture was the most effective in the rehabilitation of patients with post-stroke dysphagia, followed by CTAR. Considering that CTAR is a low-cost and highly feasible intervention, we suggest that CTAR should be selected as a rehabilitation measure for patients with post-stroke dysphagia to improve their swallowing function.

Background: Condylar erosion (CE) may indicate an active progressive stage of temporomandibular joint osteoarthritis (TMJOA), but no studies have analysed the characteristics of this population.

Objective: This cross-sectional study analysed the characteristics of TMJOA patients with CE.

Methods: A total of 267 patients were included. The severity of CE of all joints was evaluated using cone beam computed tomography (CBCT) and scored using a four-point rating scale (0-III). Patients were categorised into mild (grade I), moderate (grade II) and severe (grade III) groups. Demographic and clinical characteristics were summarised and stratified by age and erosion severity. Univariate and multivariate logistic regression analyses were performed based on the assignment of the variables.

Results: The proportion of patients under 30 years old is much higher than other age groups. Compared to adults (≥ 20 years old), a higher proportion of adolescent patients (10-19 years old) choose orthodontics department for their first consultation (p < 0.01). And adolescent patients have a higher proportion of temporomandibular joint (TMJ) noise (p < 0.05) and a lower proportion of arthralgia (p < 0.001). Significant differences exist in CE severity between adolescents and adults (p < 0.001). The severe group had the youngest patients (p < 0.05) and the highest proportion of mandibular deviation and abnormal postural habits.

Conclusions: Patients under 30 years of age constitute a significant proportion of TMJOA cases with CE. Compared to adults, adolescent patients have more severe CE and less arthralgia. Due to obvious dental and maxillofacial deformities and milder TMJ symptoms, adolescent patients may not be aware that they have TMJ disease, potentially leading to delayed treatment.

Background: Paediatric dysphagia refers to any feeding and/or swallowing problem that affects nutritional or liquid intake safety or adequacy. There is a prominent lack of available evidence-based effective therapeutic tools to facilitate the rehabilitation of feeding and/or swallowing disorders in children.

Objective: The purpose of this study was to assess the effectiveness of focal vibration therapy-Novafon as an assistive therapeutic intervention for children with feeding and swallowing difficulties.

Methods: The study involved 122 children with dysphagia who were divided into two groups: (1) 61 children who received conventional dysphagia therapy (cCDTh) and (2) 61 children who received conventional dysphagia therapy in combination with Novafon therapy (cCDTh+NTh). All children were evaluated for pre-, mid- and post-dysphagia therapy with the Gugging Swallowing Screen (GUSS) and Pediatric Eating Assessment Tool-10 (PEDI-EAT-10) in different Cypriot school and health settings.

Results: PEDI-EAT-10 total scores for both groups observed that the cCDTh+NTh group had a significant decrease in the overall median between pre- and post-dysphagia therapy total score (Median = 3.00) compared to the cTDTh score (Median = 7.00). GUSS total scores between the two groups showed an increase in overall medians but the cCDTh+NTh group (Median of pre-therapy = 16.50, mid-therapy = 19.00 and post-therapy = 20.00) noted a higher increase in medians compared to the cCDTh group (Median of pre-therapy = 15.00, mid-therapy = 16.00 and post-therapy = 17.00).

Conclusion: The present study highlights that focal vibration therapy using Novafon may serve as an effective and supportive approach within conventional dysphagia therapy for children. Further research is necessary to enhance the evidence-based literature on the use of Novafon in paediatric dysphagia.

Objectives: Oral behaviours (OB) are some oral overuse behaviours which could be observed in patients with temporomandibular disorders (TMD). This study aims to investigate the association between TMD-related quality of life and OB to enhance understanding of these behaviours.

Methods: A total of 319 participants diagnosed with TMD were included in this research. According to the diagnostic criteria for TMD, patients were divided into three subgroups: pain-related TMD (PT, n = 71), intra-articular TMD (IT, n = 91) and combined TMD (CT, n = 157). Participants completed the oral behaviour checklist (OBC), the oral health impact profile for TMD (OHIP-TMD), the generalised anxiety disorder 7-item (GAD-7) and the patient health questionnaire 9-item (PHQ-9), and demographic characteristics were collected from medical records.

Results: TMD patients with high OBC scores (25-84 points) had higher scores in six of the seven OHIP-TMD domains (all p < 0.05). Logistic regression analysis indicated that OHIP-TMD scores (OR = 1.03), younger age (OR = 0.95), education (OR = 2.80-3.10), and PHQ-9 scores (OR = 1.14) were significantly positively correlated with OBC scores (p < 0.05). After adjusting for confounding factors, the psychological discomfort (OR = 1.09) and psychological disability (OR = 1.10) domains of the OHIP-TMD were identified as independent factors associated with higher OBC scores.

Conclusions: Patients with more frequent OB exhibited a lower quality of life across nearly all OHIP-TMD domains. Higher OHIP-TMD scores and specific psychological domains were independently associated with a higher frequency of OB. The causal relationship between quality of life and OB in TMD patients requires further investigation.
