Radiologic images in dentistry are essential to perform the diagnosis, treatment, and tracking process of prognosis, thus the ability of accurate evaluation in the diagnostic images is requested for dental clinician. Radiologic interpretation means recognition of a normality and an abnormality and to report the possible diagnosis and differential diagnosis list. Therefore, dental clinicians should be familiar with the basic principle of interpretation of intraoral and extraoral radiographic images primarily used in dental clinics. Recently, dental cone beam CT is widely used for diagnositc process, thus understanding the three dimensional images is requested. The objective of this manuscript is to help the dental clinicians to interpret accurately the diagnostic images by introducing the basic principles of the step by step analytic process in the appearance of a lesion.

Internal derangement of the temporomandibular joint (TMJ) is condition in which articular disc has become displaced from its normal functional relationship with the mandibular condyle and the articular portion of the temporal bone. Common types of internal derangement include disc displacement with reduction (with or without intermittent locking), and disc displacement without reduction (with or without limited opening) classified according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Treatment varies depending on diagnosis. Therefore, differential diagnosis should be made for appropriate treatment.

Sjogren syndrome is a chronic systemic autoimmune disorder that chiefly involves the salivary gland and the lacrimal gland, resulting in xerostomia and xerophthalmia. Although the exact cause of the disease is not early diagnosis, treatment and observation must be emphasized because of its poor prognosis, such as the high occurrence of malignant lymphoma and other autoimmune disease that may be accompanied. In the present case, a twenty-year-old woman whose chief complaint was multiple dental hard tissue loss and xerostomia, which was misdiagnosed as iron deficiency anemia at first, but through re-evaluation and differential diagnosis it was Sjogren syndrome. the diagnosis approach was discussed in this report, suggesting that Sjogren syndrome should be considered as a differential diagnosis in a with xerostomia.

Pemphigus vulgaris (PV) is a chronic autoimmune bullous disease caused by autoantibodies to proteins in the oral mucosa and skin. It is a rare disease with an annual incidence of 2.059 per million in South Korea. In many patients with PV, oral mucosal lesions precede other lesions elsewhere, and oral lesions can be the only manifestation. Early diagnosis is important because the disease has a high mortality rate if untreated appropriately in the early stages, and rapid treatment initiation is associated with rapid disease control. Oral PV lesions are clinically variable. In this study, we describe oral PV lesions in a 60-year-old woman, a 75-year-old man, and a 60-year-old man presenting with various clinical presentations. Oral PV lesions can affect any part of the oral mucosa, including the buccal mucosa, gingiva, tongue, palate, and free mucosa, and can vary in appearance from desquamative gingivitis, painful ulcers, and erosions to aphthous-like stomatitis. Clinicians should be aware of the difficulty of early diagnosis in PV, particularly when oral lesions are the only manifestation, and should consider many factors, including the patient's age, to make an accurate diagnosis and manage oral lesions to improve the patient's quality of life and avoid delayed diagnosis.

Most dental pain is caused by an organic problem such as dental caries, periodontitis, pulpitis, or trauma. Diagnosis and treatment of these symptoms are relatively straightforward. However, patients often also complain of abnormal dental pain that has a non-dental origin, whose diagnosis is challenging. Such abnormal dental pain can be categorized on the basis of its cause as referred pain, neuromodulatory pain, and neuropathic pain. When it is difficult to diagnose a patient's dental pain, these potential alternate causes should be considered. In this clinical review, we have presented a case of referred pain from the digastric muscle (Patient 1), of pulpectomized (Patient 2), and of pulpectomized pain (Patient 3) to illustrate referred, neuromodulatory, and neuropathic pain, respectively. The Patient 1 was advised muscle stretching and gentle massage of the trigger points, as well as pain relief using a nonsteroidal anti-inflammatory and the tricyclic antidepressant amitriptyline. The pain in Patient 2 was relieved completely by the tricyclic antidepressant amitriptyline. In Patient 3, the pain was controlled using either a continuous drip infusion of adenosine triphosphate or intravenous Mg2+ and lidocaine administered every 2 weeks. In each case of abnormal dental pain, the patient's diagnostic chart was used (Fig.2 and 3). Pain was satisfactorily relieved in all cases.

Burning mouth syndrome(BMS) is a burning sensation in the oral mucosa and $doesn^{\circ}$Øt have any identifiable oral lesion and organic etiology. Diagnosis of BMS is mainly based on clinical features and serial exclusion of other possible causes. There is no specific examination for BMS and that could embarrasse the dentist. In this study, the characteristics, differential diagnosis and several treatments of BMS are presented so that dentists can better diagnose BMS to maintain a good relationship with the patients.

Benign fibro-osseous lesions occur when normal bone is replaced by cellular fibrous connective tissue and mineralized structures. One rare type of these lesions is the ossifying fibroma (OF). The aim of this study is to report an unusual case of OF in a 57-year-old female. Physical examination showed facial asymmetry without any tenderness, fluctuation, ocular pain, or ophthalmoplegia. Imaging exams revealed a solid mass involving the left maxilla and orbital floor. Surgical resection was performed without any complications or sequelae, and the histopathological results confirmed OF. Although recurrence is rare in this condition, the patient remains under follow-up.
