Objective: The surgical treatment of Eagle syndrome involves an intra- or extraoral approach. This systematic review set out to consolidate current knowledge on the prevalence of complications associated with intraoral and external approaches.

Methods: Seven main electronic and two gray literature databases were searched. Studies were blindly selected by two reviewers based on pre-defined eligibility criteria. Studies evaluating any type of complication in the treatment of Eagle syndrome were considered eligible. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for studies reporting prevalence data, case reports, and case series. The Comprehensive Meta-Analysis software (Software version 3.0 - Biostat, Englewood, NJ, USA) was used to perform all meta-analyses.

Results: Out of 1728 articles found on all databases, 36 were included for qualitative analysis. Twenty were included for quantitative analysis and meta-analysis.

Conclusion: In this study, the highest rate of complications was found in the intraoral approach.

Objective: This study proposes a cephalometric method to determine an individual radius of the curve of Spee in cases of occlusal prosthetic rehabilitation.

Methods: A retrospective study was conducted on 469 lateral cephalograms. Statistical analysis was performed. Correlations were computed using simple regression, Z tests, paired t-tests, and one-way repeated measures ANOVA.

Results: Regression calculations supported a link between the radius of the curve of Spee and occlusal plane inclination, Balkwill's angle, mandibular parameters (MP), with MP = corpus - ramus + Bonwill height. Based on MP, data that are accessible even in the absence of teeth, a regression formula can be proposed to provide an individualized estimation of the radius of the Spee curve (RCS): RCS = 0.624 * MP + 26.583.

Conclusion: This study proposes an individualized estimation of the RCS from only skeletal mandibular parameters: the length of the ramus, length of the corpus, and the Bonwill height.

Objective: To study the correlation between condylar morphology and clinical manifestations in patients with degenerative joint disease (DJD) of the temporomandibular joint (TMJ).

Methods: A total of 175 joints of 131 patients with DJD were included. Data on patients' basic information and symptoms were collected and analyzed. Condylar morphology was evaluated using cone beam computed tomography (CBCT). The correlation between the condylar morphology and clinical manifestations was analyzed.

Results: The prevalence of joint noises, clicks, and crepitus was 93/175 (53%), 73/175 (42%), and 20/175 (11%), respectively. Condylar anteroposterior diameter and condylar height were correlated with pain. There was a correlation between the shape of the condyle in the sagittal plane and joint noise.

Conclusion: Condylar morphology and clinical features of DJD were correlated to some extent.

Objective: To investigate the morphological and positional temporomandibular joint (TMJ) characteristics of different temporomandibular disorders (TMDs).

Methods: One hundred forty-three TMD patients were divided into three groups: Group 1: Myalgia (M), Group 2: Disc displacement with reduction (DDWR), and Group 3: Disc displacement without reduction (DDWOR). Three-dimensional positional and dimensional parameters of the TMJ, including mandibular fossa, condyle, and TMJ spaces were evaluated using cone beam computed tomography (CBCT). The significance level was p < 0.05.

Results: Mandibular condyles were significantly positioned in more vertical, posterior, and medial directions, with the reduced condylar width in the DD groups (p < 0.001). Anterior joint space was significantly higher in the DDWR group than the myalgia group; the superior joint spaces were more reduced in DD groups than the myalgia group.

Conclusion: Patients diagnosed with disc displacement showed significantly different condylar positions and joint spaces compared to the myalgia group in a skeletally comparable sample.

Objective: To evaluate the inter-examiner reliability of the Chinese version of the Axis I diagnoses of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and to compare the consistency between clinical diagnoses and magnetic resonance imaging (MRI).

Methods: Sixty-seven individuals were evaluated by three TMD specialists, and 49 underwent MRI examination. Cohen's Kappa coefficient (κ) was used to evaluate the inter-examiner reliability and the consistency between clinical diagnoses and MRI manifestations.

Results: Diagnostic agreement was good to excellent for pain and disc displacement with or without reduction (κ = 0.659-1.000). Agreement between clinical diagnoses and MRI findings was fair to good (κ = 0.400).

Conclusion: Inter-examiner diagnostic reliability using the Chinese version of the DC/TMD Axis I instruments was excellent, especially for arthrogenic TMDs.

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.

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 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: The aim of the study is to verify the impact of anxiety on temporomandibular disorders (TMD) by using specific questionnaires in a Turkish sample.

Methods: This survey was conducted on 292 patients with a mean age of 38.59 ± 10.38 using Helkimo index, Oral Health Impact Profile (OHIP-14), and State Trait Anxiety Inventory (STAI). Spearman Correlation and Fisher Freeman Halton analyses were used for the statistical analysis.

Results: There was no statistically significant difference between the Helkimo anamnestic dysfunction (HAD) levels in terms of OHIP-14 total scores or STAI state scores. There was, however, a statistically positive correlation between STAI state and OHIP-14 total values at 18.4%, a positive correlation between the STAI trait and OHIP-14 total values at 29.8%.

Conclusion: No significant correlation was observed between OHIP-14 total scores, STAI state scores, and HAD levels. Therefore, this study did not find a significant relationship between TMDs and anxiety.
