Objective. The aim of this study was to quantitatively evaluate the salivary tumor necrosis factor-alpha (TNF-α) level in oral lichen planus patients and to compare the levels of TNF-α between saliva and serum of OLP and controls. Methods. Serum and whole saliva from 30 patients with active lesions of oral lichen planus (OLP) and 30 healthy persons were investigated for the presence of TNF-α by enzyme immunoassay. Student's independent t-test and two-sample binomial proportion test were used to calculate significance of the mean values of TNF-alpha in serum and saliva and to determine the proportions of the detected and nondetected samples in both groups. Results. Proportion of detection and the mean of detectability between saliva and serum of Group B show an almost equal value, which suggests that saliva can be a good alternate to serum to analyze TNF-α in oral lichen planus patients.

Psoriatic arthritis (PsA) is a chronic inflammatory condition affecting psoriatic patients. Its clinical manifestations in patients can vary over time, advancing from one joint to the next with an intermittent pattern of exacerbation and remission. The condition shares similar manifestations with rheumatoid arthritis (RA), ankylosing spondylitis, and reactive arthritis; hence, a comprehensive examination is required for a proper diagnosis and management. It is associated with an increased risk of comorbidities affecting patients' well-being. There have been few incidences of involvement extending to the temporomandibular joint (TMJ), but a proper record needs to be maintained to evaluate its part in PsA. In this report, we present a case of PsA in which the patient complained of ear pain and was discovered to have early alterations in the TMJ.

Oral potentially malignant disorders (OPMD) are diverse lesions associated with an increased likelihood for malignant transformation to oral cancer. The most frequently encountered OPMD in clinical practice are Oral Leukoplakia and oral submucous fibrosis (OSMF). The use of tobacco is consistently linked with leukoplakia and areca/betel nut with OSMF. Histopathological features of oral epithelial dysplasia, its varying grades are of immense clinical significance to evaluate its ability for malignant transformation. We report a case of homogenous leukoplakia and OSMF, two oral potentially malignant disorders occurring at the same site with high-grade dysplasia and its management using lasers.
