Background The temporomandibular joint (TMJ) is one of the most complex joints in the body. Temporomandibular disorders (TMD) are among the most troublesome disorders for patients, as they can cause pain, affect oral functions and disturb dentists on the level of diagnosis and treatment. The most common symptoms of temporomandibular joint disorders are articulated sounds (such as clicking or TMJ crepitation), joint pain in comfort and function situations (jaw movements), pain or strain in masseter and jaw muscles and or restricted mandibular movements. One of the most modern biocompatible substances used to treat joint disorders, including the TMJ, is platelet-rich plasma (PRP) and injectable platelet-rich fibrin (I-PRF). This study aims to evaluate the efficacy of platelet-rich fibrin (I-PRF) intra-articular injections in managing internal derangements of temporomandibular. Methods Twenty patients suffering from a unilateral click due to temporomandibular disorders were individually injected with 1 mL of (I-PRF) twice 1 week apart into the superior joint space of the TMJ with the internal disorder. Data were recorded and evaluated by the Helkimo index. This evaluation was conducted three times; 1 week after the first injection, 1 week after the second injection, and 6 months after the first injection. Results The clicking disappeared entirely in 14 out of 20 patients after 1 week of getting the first injection, and in all patients after 1 week of getting the second injection, and returned to two of them after a six-month since the first injection. Conclusion Preliminary results showed the efficacy of the Injectable Platelet-Rich Fibrin (I-PRF) in managing articular clicking in patients with internal disorders of the temporomandibular joint. Injectable Platelet Rich Fibrin has significant clinical efficacy in treating the articular clicking resulting from internal temporomandibular joint disorders.

BACKGROUND A patient-centred perspective has been connected to humanity. Medical practitioners should respect patients' independence, values, and aspirations. They should involve them in treatment decision-making, and communicate with them. Patient care supported by an evidence-based conceptual framework to evaluate and promote the concept and values of humanity in medical curricula within universities, particularly Syrian universities affected by a terrible crisis that necessitated the establishment of curricula based on humanity and the evaluation of students' humanity. OBJECTIVE This study aims to design a humanity scale for medical, dental and pharmacy students. METHODS The study was conducted in a methodological design to study the reliability and validity of the Syrian Humane Scale. The study included students in the Faculties of Medicine, Dentistry or Pharmacy. A Medical Humanity Scale includes 27 items that analyse human values: patient-oriented, respect, empathy, ethics, altruism and compassion. Simplicity, clearness and orientation are the factors that were considered while the items were formed to decrease the wrong interpretation of the results. The 7-Point Likert has been implemented. The Delphi technique and factors analysis was used. Then, validity and reliability were analysis. RESULTS The factors analysis appears that the percentage of variables between the first and second factors is greater than 10%, and this confirms that the scale is only one group. Cronbach's alpha for the overall scale was (0.735>0.700). Thus, the scale has acceptable reliability and validity. CONCLUSIONS The Medical Humanity Scale is a reliable and valid scale for measuring the human aspect of medical college students.
