“…In typical psoriasis, it is not affected by any lesions, while in the arthritic form, although rarely, an inflammation can occur and, consequently degenerative changes such as erosion and resorption of condylar processes bone, the deposition of calcium deposits in the joint space, and ankylosis. [40][41][42] Changes are usually unilateral. 41 Apart from the changes visible in x-ray pictures, the patients with psoriasis, especially those with psoriatic arthritis, more often than healthy controls, present symptoms and dysfunctions of TMJ such as acoustic symptoms, pain, and bruxism.…”

Psoriasis is one of the most frequent skin diseases. The cause of psoriasis is not fully expained as there are many factors (infectious, traumatic, hormonal, and chemical) that may play a role in the manifestation of its symptoms. One of the factors that may contribute to the appearance of psoriatic lesions may be the lesions in the oral cavity. The occurrence of lesions in the oral cavity is defined as rare, what can be explained by their nonspecific clinical image, and also by the possibility of being overlooked. Most characteristic symptoms of psoriasis occurring in the oral cavity are the geographic tongue and fissured tongue. It is also believed that there is a correlation between psoriasis and oral health‐ the periodontal and teeth condition as well as changes in saliva secretion. The psoriasis arthritis changes can also affect temporomandibular joint and impair the function of stomatognathic system. Because of these reports, cooperation of dermatologists and dentists in psoriasis care seems to be necessary.

“…Barrera-Mora [9] conducted a comprehensive study suggesting that unilateral scissor bite should be regarded as a risk factor for TMD. In a scissor bite relationship, the abnormal buccolingual position of the posterior teeth hinders the transmission of occlusal forces along their long axes [10] .…”

Objective The objective of this study was to measure and analyze the joint space, condylar morphology, and thickness of the roof of the glenoid fossa (RGF) in patients with unilateral second molar scissor bite using cone beam CT (CBCT). Methods A total of 80 patients were included in this study. Forty patients with a normal posterior occlusal relationship, who attended the Department of Orthodontics at the First Hospital of Shanxi Medical University from December 2021 to August 2023, were selected as the control group. The experimental group consisted of 40 patients with unilateral second molar scissor bite during the same period. All patients underwent CBCT scanning, and the resulting images were analyzed using the NNT viewer software in multiplanar reconstruction (MPR). Axial, coronal, and sagittal adjustments were made for each patient. Results In the control group, the right and left joint spaces (PS, SS, AS), the height of the upper part of the condyle, and the depth of the glenoid fossa did not show statistically significant differences (P > 0.05). When comparing bilateral condylar morphology and joint space in the experimental group, it was found that the posterior joint space on the scissor bite side was greater than that on the normal occlusion side, while the anterior joint space on the scissor bite side was smaller than that on the normal occlusal side. Additionally, the height of the upper condyle and the depth of the joint fossa on the scissor bite side were greater than that on the normal occlusal side, with statistically significant differences (P < 0.05). However, there were no statistically significant differences in SS, internal and external joint diameter, as well as anterior and posterior diameters (P > 0.05). The comparison of the minimum thickness of the roof of the glenoid fossa in both the sagittal and coronal directions between the patients in the experimental group and the control group showed no statistically significant difference (P > 0.05). Furthermore, the asymmetry index of the supracondylar height in the control group was significantly smaller than that in the experimental group, displaying a statistically significant difference (P < 0.05). The differences in the asymmetry indices of the anterior and posterior diameters of the condyle, as well as the inner and outer diameters, were not statistically significant (P > 0.05). When analyzing the position of the condyle in the sagittal direction of the glenoid fossa in the patients of the control group, it was observed that the majority were in the anterior and medial positions, with only 10% and 5% being in the posterior position. However, the analysis of the condyle position in the sagittal direction of the articular fossa in the experimental group revealed statistically significant differences (P < 0.05), with the condyle position on the scissor bite side being more anterior. Conclusion Unilateral second molar scissor bite can result in anterior displacement of the condyle, greater height of the condyle superiorly as well as the depth of the glenoid fossa, and the above changes can result in a patient being more susceptible to temporomandibular joint disorder.

“…More recent studies concluded that there is no scientific evidence proving that orthodontic treatment will prevent the development of future TMD, or cure an existing disorder. (5) There are not many studies done to co-relate orthodontic treatment and TMD in this part of the world. This study is aimed to determine the prevalence of TMJD in patients during or after fixed orthodontics treatment and identify the inter-relationship between different aspects of orthodontic treatment and TMD in Qassim region of Saudi Arabia.…”

Introduction:-TMD is the main cause of pain of non-dental origin in the oro-facial region and is multifactorial in nature. Orthodontic treatment has been linked to TMD since 1980s, which started a series of studies to find out any co-relation between orthodontic treatment and TMD. Objective:-To determine the prevalence of TMJD in patients during or after fixed orthodontic treatment in Qassim Area. Materials and Methods:-It was a cross sectional study done on 232 orthodontic patients. Data collection was done by self-administrated questionnaire. Result:-Data analysis was done by SPSS version 22.Results showed there was no significant co-relation between TMD and orthodontic treatment. Conclusion:-Orthodontic treatment is not a cause of TMD.
