Objective: To examine the SCUBE1 level, a biomarker in vascular biology that could determine the prognosis of cardiovascular events during OSA treatment.

Methods: In total, 129 patients were included in the study. Thirty were diagnosed with simple snoring and 99 with OSA.

Results: In males, significant correlation was determined between SCUBE1 non-REM AHI, hypopnea index, total apnea index, mean SO₂, minimum SO₂, and < 90% saturation duration.

Conclusion: Serum SCUBE1 levels increased more in male patients with severe OSA compared to other OSA levels, and high serum SCUBE1 levels were found to be associated with lower oxygen levels in OSA patients. The SCUBE1 biomarker can correlate with severe OSA in males. There was a statistically significant difference between OSA groups in terms of SCUBE1 score for male patients (p = 0.002) but not for females (p = 0.498). It is important that future SCUBE1 studies evaluate males vs. females.

Background: The opinion on whether a patient with an anterior open bite should be treated surgically or not is controversial. These patients generally suffer from associated discomfort due to their occlusal instability and musculoskeletal pain.

Clinical presentation: A 60-year-old woman visited the clinic with dental mobility of her upper central incisors as her chief complaint. She had a severe anterior open bite, with a history of continuous grinding and multiple dental restorations in poor condition. Additionally, she suffered neck pain with movement restrictions.

Conclusion: Dentists can evaluate and treat patients with an anterior open bite using this integrative model (physical therapy/dentistry) as a possible alternative as part of the treatment for anterior open bite patients.

Objective: To explore the relationship between the size of temporomandibular joint (TMJ) condyle and the sagittal disc-condyle position and the relationship between the condylar size and craniofacial structure.

Methods: Seventy-four subjects (23.82 ± 3.77 years) underwent cone beam computed tomography (CBCT) and lateral cephalograms for orthodontics and volunteered to undergo magnetic resonance imaging (MRI). Mimics was used to calculate the volume and surface area of the condyle. MRI was used to evaluate the sagittal disc-condyle position. The lateral cephalograms were analyzed by Jarabak analysis.

Results: The condylar volume and surface area were negatively correlated with the sagittal disc-condyle position. The condylar volume and surface area were positively correlated with Ar-Go, S-Go, and S-Go/N-Me*100% (p < 0.05) and negatively correlated with ∠Ar-Go-Me and ∠N-Go-Me (p < 0.05).

Conclusion: Condylar size was negatively correlated with the sagittal disc-condyle position. The condylar size was correlated with the vertical skeletal pattern.

Objective: To determine the prevalence of self-reported bruxism, awareness of bruxism's adverse effects, and bruxism management among Thai undergraduate dental students.

Methods: An online self-reported questionnaire was designed and tested for validity and reliability and then distributed to dental students at 12 universities in Thailand from September 2020 to January 2021.

Results: There were 464 respondents (338 females and 126 males) with an average age of 21.42 ± 2.06 years. The prevalence of self-reported awake and sleep bruxism was 35.78% and 37.28%, respectively, and 19.40% had both awake and sleep bruxism. Awareness scores were higher for dentists than for patients (p< 0.001). Only 12.14% of sleep bruxers still wear an occlusal splint for bruxism management.

Conclusion: The prevalence of self-reported awake and sleep bruxism was high among Thai dental students. They are well aware of the adverse effects of bruxism with inappropriate management of the condition.

Objective: To assess the impact of the university context of different academic fields and class times and the sociodemographic context on the symptoms of temporomandibular disorder (TMD).

Methods: A total of 2912 university students, divided into 26 undergraduate courses distributed in the fields of biology and exact and human sciences in the day and night participated in this study. The symptoms of orofacial pain and TMD were assessed using a self-explanatory questionnaire for screening, as recommended by the American Academy of Orofacial Pain. The data were analyzed using frequency distribution tables and multiple logistic regression at a 5% significance level.

Results: There was a significant association between the female sex and the attended class time. Women and undergraduates of night courses were 1.60 times more likely to present symptoms related to TMD compared to women studying during the day.

Conclusion: It was concluded that, within the university context, women and undergraduate students enrolled in night courses were more likely to present with TMD symptoms.

Objective: To assess the efficacy of microcurrent electrical nerve stimulation (MENS) therapy in treating myofascial pain of the masticatory muscles.

Methods: In this systematic review and meta-analysis, the efficacy of MENS was evaluated, with the primary outcome being the reduction in pain on palpation of the masticatory muscles.

Results: Four independent comparisons based on three studies were included in the meta-analysis (n = 140). In comparison to placebo and other therapies, treatment with MENS showed an improved mean reduction in pain of -0.57 points (CI: -0.91 to -0.23 points, I² = 83.7%).

Conclusion: Evidence from this meta-analysis shows that MENS is an effective non-invasive treatment that can be used to reduce pain in patients with myofascial pain of the masticatory muscle; however, the study was limited by the small number of articles relevant to the research question as well as variability between the selected studies.

Objective: To assess the repeatability and kinematic data of Modjaw® recordings from a group of asymptomatic patients.

Methods: Modjaw® mandibular kinematic data were recorded for 22 asymptomatic volunteers (DC/TMD questionnaire). Sagittal (SCI at 3 and 5 mm) and transversal (TCI at 4 mm) condylar inclination values of the instantaneous center of rotation were measured over two recording sessions. The repeatability of recordings was determined from the intraclass correlation coefficient (ICC), which is based on a one-way random-effects ANOVA.

Results: The repeatability of recordings was found to be good to excellent. The mean TCI in mediotrusion was 7.1° ± 5.1, and the mean SCI in protrusion was 51.07° ± 9.43.

Conclusion: The Modjaw® device reliably records the patient's real hinge axis kinematics during functional mandibular movements. Data can be transferred with the patient's personal reference plane and digital casts to the CAD/CAM software.

Objective: To estimate the prevalence of temporomandibular dysfunction in scleroderma patients according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and to correlate it with disease variables.

Methods: Temporomandibular dysfunction was evaluated in 75 scleroderma patients and 74 healthy controls using DC/TMD. Gastrointestinal symptoms were evaluated through the University of California Los Angeles (UCLA) score in scleroderma patients.

Results: There was no difference of prevalence in temporomandibular dysfunction [30 (40%) vs 30 (40.5%); p > 00.05] between scleroderma patients and healthy controls. Scleroderma patients had a significant reduction in all oral movements compared to healthy controls. Scleroderma patients with temporomandibular dysfunction had a statistically higher score in the UCLA distention/bloating item [1.75 (0.5-2.38) vs 0.75 (0.25-1.75); p < 0.05] than scleroderma patients without temporomandibular dysfunction.

Discussion: Temporomandibular dysfunction prevalence between scleroderma patients and healthy controls is similar. In scleroderma patients, temporomandibular dysfunction reduces oral mobility and opening, which worsens distension/bloating.

Objective: To evaluate radiological characteristics of the temporomandibular joint.

Methods: Retrospective study of images of 20-80 year-old patients. Two independent clinicians analyzed the images, and a radiological score was obtained, considering sclerosis, osteophites, cysts, and erosion.

Results: Seventy eight percent of the joints belonged to females. The main complaints were pain and headache (54.5%) and reduced motion (21.2%). The most common diagnoses were disc dislocation with reduction (35.9%), myofascial pain (20.7%), and osteoarthritis (15.2%). The majority of the joints (96.5%) showed degeneration, with an average radiological score of 3.86 ± 1.47 (0-8). Non-parametric tests showed that females had significantly higher radiological scores (p = 0.014), and TMD-joint patients had higher scores than TMD-muscle patients (p = 0.013). No statistically significant association between radiological scores and chief complaint.

Conclusion: There were differences among the radiological findings between genders and joint/ muscle TMD, as well as across diagnoses, as expected.
