Correlation between joint effusion and morphology of the articular disc within the temporomandibular joint as viewed in the sagittal plane in patients with chronic disc displacement with reduction: A retrospective analytical study from magnetic resonance imaging.

Objective: To evaluate the presence of joint effusion and morphology of the articular disc (AD) viewed in the sagittal plane in patients with disc displacement with reduction (DDWR) and to correlate the results with clinical findings.Methods: The sample consisted of 116 patients with DDWR who were evaluated clinically and with magnetic resonance imaging. The AD's morphology was assessed from the sagittal view with the mouth both open and closed. The statistical analysis demonstrated a significance level of 5%.Results: With a mean age of 35 years, 79 patients (68.10%) showed joint effusion, and the female gender was most prevalent (p < 0.05). The results showed a relationship between joint effusion and DDWR in both sides (p < 0.05).Conclusion: Clinically, the present study can infer that DDWR is associated with joint effusion, and females are the most affected. It can be suggested that the pain may be associated with joint effusion.

Correlation between age, gender, and the number of diagnoses of temporomandibular disorders through magnetic resonance imaging: A retrospective observational study.

OBJECTIVE: The aim of this study was to evaluate the correlation among age, gender and the number of temporomandibular disorder (TMD) findings. METHODS: The records from 228 patients with TMD were analyzed for the presence of these findings: morphological changes, disc displacement with reduction (DDWR) and without reduction (DDWOR), bone edema, effusion, and avascular necrosis. Statistical analyses were conducted using multinomial regression with a 5% significance level. RESULTS: DDWR was the most frequent finding. Group 1 was composed of 94 patients (41.22%), Group 2, of 67 patients (29.38%), and Group 3, of 67 patients (29.38%). Men were significantly less likely to belong to Group 3 than women (p = 0.5517). Older patients were slightly more likely to fall in Groups 2 and 3 than in Group 1. DISCUSSION: Women were shown to be more susceptible to developing a higher number of concomitant conditions than men, and the number of findings tended to increase with age.

Correlation between clinical variables and magnetic resonance imaging findings in symptomatic patients with chronic temporomandibular articular disc displacement with reduction: A retrospective analytical study.

Objective: To correlate the clinical aspects of symptomatic patients with chronic articular disc displacement with reduction with alterations in the articular disc (AD) morphology and sagittal position. Methods: Records from 109 patients were selected that included data on AD morphology and sagittal position as determined by MRI. According to the MRI results, the sagittal position and AD morphology with opened and closed mouth were correlated with many clinical variables. Results: More than half of the patients studied were female, and the biconcave and hemiconvex morphologies were most common. Thirty-four patients (31.3%) presented with restricted maximum interincisal distance (MID). The biplanar morphology was associated with eccentric bruxism and MID (p < 0.05). Visual analog scale (VAS) scores between 2 and 7 were shown to be risk factors (p < 0.05). Conclusion: The mouth position can influence AD morphology and eccentric bruxism. VAS scores and unknown etiology were risk factors.

Exuberant manifestation of neurofibromatosis type 1 affecting 3 generations: delayed diagnosis and the importance of the multidisciplinary approach

Neurofibromatosis type 1 (NF1) is an autosomal dominant inherited disorder caused by mutations of chromosome 17. The NF1 clinical diagnosis is based on pre-established criteria, including the presence of cutaneous neurofibromas, café au lait spots, and iris (Lisch) nodules. Early detection and a multidisciplinary approach are essential for the prevention of complications, including problems of function, aesthetics, and self-esteem, as well as the occurrence of malignant transformation. This study reports a case of an exuberant NF1 manifestation diagnosed by a dental surgeon, whose investigation of a family led to the diagnosis of NF1, with different expressivities, in 3 generations(AU).

Accuracy of two-dimensional pharyngeal airway space prediction for bimaxillary orthognathic surgery.

PURPOSE: The aim of this retrospective study was to evaluate the accuracy of two-dimensional (2D) virtual surgical planning (VSP) of pharyngeal airway space (PAS) in patients submitted to bimaxillary orthognathic surgery. METHODS: This study was conducted with lateral cephalograms acquired through cone-beam computed tomography records of 33 patients, divided into group 1-patients submitted to maxillary advancement and mandibular setback (n = 17) and group 2-patients submitted to maxillomandibular advancement (n = 16). Records were taken 1 to 2 months prior to surgery, which was used to perform the 2D VSP (Tp), and 6 to 8 months after surgery (T1). In Dolphin Imaging software, the anteroposterior size of the PAS was calculated at the level of four craniometric points: A, occlusal plane (Mx), B, and pogonion (Pog). Two previously calibrated examiners performed these measurements. Statistical analyses were conducted using Kendall and t tests at a 5% level of significance. RESULTS: There was a concordance between the two examiners at all points and times. In group 1, points A and B have statistically significant differences between the PAS measurements performed in Tp and T1, while in group 2, none of the PAS points showed statistically significant differences when comparing Tp to T1. CONCLUSIONS: 2D computer-based cephalometric prediction in Dolphin Imaging software offers a good orientation to professionals during the surgical procedure of bimaxillary surgeries since its use is considered clinically relevant in daily practice.
