“…Similar to Kilic's study, Tortarolo et al observed a condylar asymmetry index (CAI) in children with a high value in unilateral reverse occlusion, but these studies only investigated unilateral posterior crossbite compared to the control group with normal occlusion [49]. The novelty of our study comes from the fact that classification was made by classes of malocclusions, including in the study, in addition to UPC, the malocclusions from Angle's classification: Class I, Class II/1, Class II/2 and Class III.…”

This study is intended to focus on the evaluation of posterior vertical mandibular asymmetry by calculating the mandibular asymmetry index on the panoramic radiography in different types of malocclusions, considering the sexual dimorphism in children and adolescent patients and performing a comparative analysis between these groups. In this context, a cross-sectional study was conducted for a group of 214 patients (134 females and 80 males with a mean age of 9.5 ± 2 years). The asymmetry index was calculated for each patient according to the Habets method. The results were analyzed by using the independent Student t-test, ANOVA and Mann–Whitney U-test at the 95% confidence level (p < 0.05). The results of the analyses showed a statistically significant difference between males and females at the level of the condylar index (p = 0.023) and a significant difference in the unilateral posterior crossbite in the Mann–Whitney U test (p = 0.01). No statistically significant differences were found between males and females in the index of the mandibular ramus and condyle-plus-ramus. The highest value of the asymmetry index was recorded at the level of the condyle. We found higher values of asymmetry in Angle Class I malocclusions in all groups and in Class II/1 in the group of females.

“…Prolongation of posterior crossbite can cause permanent changes in bony support, and possibly in the growth center at the TMJ, showing that malocclusions, especially transverse anomalies, have a marked effect on mandibular condyle morphology [ 23 , 24 ]. Patients with bilateral posterior crossbite have asymmetrical condyles that might be at risk for the development of future skeletal mandibular asymmetries [ 25 – 28 ].…”

Objective Unilateral posterior scissors-bite (uPSB) malocclusion is common clinically. This study aimed to investigate the condylar morphological alterations and condyle-fossa relationship in patients with uPSB, through cone beam computed tomography (CBCT) and three-dimensional reconstructive imaging technique. Methods A retrospective study was designed to comparatively analyze 95 patients with uPSB between July 2016 and December 2021. They were divided into three subgroups: 12 to 20, 21 to 30, and ≥ 31 years, according the age distribution. The morphological parameters regarding condyle, fossa, and joint space after three-dimensional reconstruction were measured and analyzed by a series of digital software. SPSS 26.0 software package was performed for statistical analysis on data sets, using paired t–test, one–way analysis of variance, Wilcoxon signed–rank sun test, Kruskal–Wallis H test, and Bonferroni correction. Results The condylar volume (CV) of scissors-bite side was greater than that of the non-scissors-bite side (CVA = 1740.68 ± 559.80 mm3 > CVN = 1662.25 ± 524.88 mm3, P = 0.027). So was the condylar superficial area (CSA) (CSAA = 818.71 ± 186.82 mm2 > CSAN = 792.63 ± 173.44 mm2, P = 0.030), and the superior joint space (SJS) [SJSA = 2.46 (1.61, 3.68) mm) > SJSN = 2.01 (1.55, 2.87) mm), P = 0.018], and the anterior joint space (AJS) (AJSA = 3.94 ± 1.46 mm > AJSN = 3.57 ± 1.30 mm, P = 0.017). The constituent ratios of the different parts of the bilateral condyles were 23% on the posterior slope, 21% on the top, 20% on the anterior slope, 19% on the lateral slope and 17% on the medial slope, respectively. Conclusion Due to long-term abnormal occlusion of uPSB, the pathological bite force in temporomandibular joint would cause changes in the shape of the condyle. Among them, CV, CSA, SJS and AJS had significant changes in the scissors-bite status, which has the greatest damage to the posterior slope of the condyloid process.

“…In this regard, it is important to underline the results of recent research on the cranial structure and condylar asymmetry checked on panoramic X-rays. In patients with RA, compared to a healthy adult control group, the condyles showed a bilateral asymmetry in RA patients due to the high turnover of this joint reacting to severe systemic inflammation [33]. So, it is pivotal to diagnose TMJ early and monitor it in conditions of arthritis, not only assessing the signs and symptoms revealed by patients but also evaluating predictors through additional serological and instrumental exams.…”

Background: Rheumatoid Arthritis (RA) is a systemic and chronic autoimmune disease with inflammation at the synovial joints. The purposes of this study were to evaluate the correlation between serological variables and temporomandibular disorders (TMDs) in patients diagnosed with RA, evaluated through diagnostic criteria for temporomandibular disorders (DC/TMD), and to check the influence of comorbidities on the different TMD signs and symptoms, or any serological variables. Methods: This observational cohort research study included seventeen patients affected by RA. The comorbidities and some variables from the initial serological analyses were collected from the clinical rheumatological charts. Then, the presence of any of the following TMD signs/symptoms, temporal myalgia, temporomandibular joint arthralgia, click or crepitus, was evaluated through the symptom questionnaire of the DC/TMD during clinical evaluation following the DC/TMD examination form. Results: Rheumatoid factor (RF), anticitrullinated protein antibodies (ACPA), and anti-nuclear antibody (ANA) positivity were present in 82.4%, 52.9%, and 41.2% of patients, respectively. Indicators of tissue inflammation were evaluated with median values of 21 mm/h for erythrocyte sedimentation rate (ESR) and 0.50 mg/dL for C-reactive protein (CRP). The RA patients presented comorbidities such as hypertension in 70.6% and diabetes in 23.5%. Negative ACPA had a significant association with myalgia (p = 0.03), and positive ANA was significantly associated with crepitus (p = 0.05). Conclusion: ANA and ACPA evaluation can be considered predictive serological tests associated with specific TMDs. Conversely, no influence of any comorbidities was found between different TMD signs and symptoms, or any serological variables.
