Objective: To three-dimensionally evaluate the position and morphology of the TMJ in skeletal Class I with variable degrees of overbite and overjet in comparison with normal peers.

Methods: Pretreatment CBCT scans of 126 adults were retrieved. Based on the severity of overjet and overbite, the sample was divided into three main groups and six subgroups (18 patients each): the first group with a normal overbite and variable overjet degree and the second group with normal overjet and variable overbite degree. These six subgroups were compared with a third control group of normal overjet and overbite.

Results: There were significant differences in vertical condylar position, vertical and anteroposterior condylar inclinations, condylar height, and significant posterior condylar positioning in severe deep overbite, compared with the control group.

Conclusion: There were significant changes in the TMJ components in severe deep overbite cases. Therefore, sever deep overbite could be considered a predisposing factor for temporomandibular disorders.

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.

This study was conducted to achieve an understanding of the potential applications of Kinesio Taping® (KT) in the craniomaxillofacial region. A comprehensive search of pertinent literature was performed through PubMed, Medline, Google Scholar, ProQuest, and ScienceDirect. The focused question that was addressed was, "What are the potential applications of KT in the craniomaxillofacial region?". The preliminary search identified 52 studies. Once duplicates were removed, the remaining 43 titles/abstracts were screened, where 9 studies were excluded and the remaining 34 were assessed. Three additional studies were obtained through reference review of the retrieved articles. KT is being used for the management of various conditions, including temporomandibular joint disorders, side effects associated with maxillofacial surgeries, various neurological conditions, etc. KT has not been proven as a reliable independent treatment option; however, it is considered to be useful as a complementary option to improve treatment outcomes for various conditions.

Objective: To identify profiles of demographic, clinical, and oral health impact characteristics of individuals with temporomandibular disorder (TMD).

Methods: Four hundred ninety-six TMD patients (260 females) and 30 young controls were included. Sociodemographic, clinical, and Oral Health Impact Profile (OHIP-14) data were gathered and analyzed by Cluster, ANOVA, and regression analyses.

Results: Three clusters were identified: "Pain and depression symptoms" with participants with higher pain, depression, and OHIP-14 scores (59% females); "Chronic diseases" included older participants with current chronic diseases and medical treatment; "Healthier individuals" included younger individuals with lower chronic diseases, pain, and depression frequencies, whose OHIP-14 scores did not differ from controls (p = 0.079). OHIP-14 scores were predicted by age, pain, and depression.

Conclusion: Distinct profiles of individuals with TMD were identified, emphasizing the complex interactions between coping ability, general health, and psychosocial aspects that must be monitored.

Objective: This study aimed to investigate the potential genetic link between sleep traits and periodontitis.

Methods: A two-sample bidirectional Mendelian randomization (MR) analysis was conducted using publicly available genome-wide association studies data on chronotype, daytime sleepiness, daytime napping frequency, insomnia, sleep duration, snoring, and the apnea-hypopnea index (AHI), along with a separate dataset on periodontitis.

Results: Chronotype (OR = 0.929, 95% CI = 0.788-1.095), daytime sleepiness (OR = 0.492, 95% CI = 0.186-1.306), daytime napping frequency (OR = 1.178, 95% CI = 0.745-1.863), sleep duration (OR = 0.868, 95% CI = 0.644-1.169), AHI (OR = 1.124, 95% CI = 0.980-1.289), insomnia (OR = 0.832, 95% CI = 0.440-1.573), and snoring (OR = 0.641, 95% CI = 0.198-2.075) had no effect on periodontitis. Similarly, periodontitis demonstrated no significant effect on sleep traits.

Conclusions: There is no evidence of a bidirectional genetic relationship between sleep traits and the risk of periodontitis.
