Background: Erythema multiforme is an acute inflammatory hypersensitivity reaction triggered by different infections and drugs characterised clinically by typical target or iris lesions. It is clinically classified into EM minor, EM major depending on the severity and serious complications like Steven Johnsons syndrome and Toxic Epidermal Necrolysis may be seen. Treatment involves identifying the triggering factor followed by corticosteroid and anitihistamines in mild cases and anitiviral therapy like prescribing acyclovir in herpes associated erythema multiforme.

Background: The temporomandibular joint (TMJ) is considered a complex joint. Temporomandibular disorders (TMDs) are a common cause of musculoskeletal pain. At least one TMD symptom is seen in 33% of the population and 3.6% to 7.0% of the population shows significant severity warranting treatment. Magnetic resonance imaging (MRI) is better for the evaluation of disc and adjacent soft-tissue structures compared to cone beam computed tomography. MRI allows articular disc assessment in open and closed mouth positions. MRI has 95% accuracy in the assessment of disc disorders and 93% accuracy for osseous changes. Materials and Methods: A cross-sectional study was performed with a sample size of 21 patients as per inclusion and exclusion criteria. MRI findings were noted and compared with clinical findings. Results: As per our study, the most common age group is between 20 and 35 years. Of 42 TMJ, 41 joints show disc displacement changes and one TMJ was normal. Disc displacement with reduction is less than disc displacement without reduction. Left TMJ is more affected as disc displacement without reduction, as compared to the right side. Two TMJ were with posterior DD. Four TMJ shows anteromedial and 4 TMJ shows anterolateral DD. Six joints have a subluxation. Conclusion: In our study, we found that MRI in TMDs is more reliable and accurate for the diagnosis of DD.

Background: The stomatognathic system (SS) is a functional unit of the body formed by the orofacial structures, together with peripheral sensory and motor neuronal connections to perform different functions like mastication, speech, and deglutition. Stomatognathic system consists of skeletal components (maxilla and mandible), dental both maxillary and mandibular arches, soft tissue (salivary glands, their nervous and vascular supplies), and temporomandibular system, that is, temporomandibular joints (TMJ; which connects the mandible to the base of the skull), muscles of mastication and their ligaments and nerves (III, IV, V, XI) which regulates and co-ordinates all its structures. The stomatognathic system also plays an important role in postural control. In balance of imbalance stomatognathic system components such as occlusion may cause temporomandibular joint disorder (TMD), TMDs may affect neck and back muscles. Aims and Objectives: To evaluate the dentition status and TMDs in patients with chronic neck and/or back pain and to correlate dentition status and TMDs in both neck and back pain patients. Material and Methods: A cross-sectional study was carried out on 300 patients. Patients were selected according to inclusion and exclusion criteria. Findings were noted in specialized case history proforma. Results: Out of 300 patients, 116 (38.67%) were males and 184 (61.33) were females. The mean age of patients referred for the study was 38.09 years. The most common dental finding in both chronic neck and/or back pain patients was flat curve of Wilson's (90%) whereas the least finding found was Grade III tooth mobility (0.04 ± 0.31 teeth). In TMDs most common finding was deviation of jaw (79.3% in neck and 100% in back pain) whereas the least finding found was deflection of jaw (50% in neck and 48.2% in back pain). Statistical analysis: The result was found highly significant (p-value <0.05). Conclusion: There was an association between disturbed dentition status, temporomandibular joint disorders, chronic neck and back pain.
