This study was conducted as part of a series of studies to introduce the Convolutional Neural Network(CNN) into the diagnostic field of osteoporosis. The purpose of this study was to compare the results when testing Digital Radiography(DR) and Computed Radiography(CR) panoramic radiographs by CNN that were trained by DR panoramic radiographs. The digital panoramic radiographs of females who visited for the purpose of diagnosis and treatment at Chonnam National University Dental Hospital were taken. Two Oral and Maxillofacial Radiologists were selected for the study to compare the panoramic radiographs with normal and osteoporosis images. Among them, 1068 panoramic radiographs of females{Mean [± standard deviation] age: 49.19 ± 21.91 years} obtained by DR method were used for training of CNN. 200 panoramic radiographs of females{Mean [± standard deviation] age: 63.95 ± 6.45 years} obtained by DR method and 202 panoramic radiographs of females{Mean [± standard deviation] age: 62.00 ± 6.86 years} obtained by CR method were used for testing of CNN. When the DR panoramic radiographs were tested, the Accuracy was 92.5%. When the CR panoramic radiographs were tested, the Accuracy was 76.2%. It can be seen that the CNN trained by DR panoramic radiographs is suitable to be tested with the same DR panoramic radiographs.

Histiocytic necrotizing lymphadenitis (Kikuchi-Fujimoto disease, KFD) is a benign self-limiting lesion that can self-heal when no severe symptoms are present. KFD resembles tuberculous lymphadenitis and malignant lymphoma. Thus, early differential diagnosis will minimize unnecessary evaluation and treatment. Histological examination of a lymph node biopsy or fine needle aspiration could be a reliable method for KFD diagnosis. This study reports a case of histiocytic necrotizing lymphadenitis of the right cervical lymph node in a 52-year-old female patient. According to the fine needle aspiration biopsy result, the patient was diagnosed with Kikuchi-Fujimoto disease and treated with prednisolone (15 mg/day). After treatment, there was no recurrence or adverse event.

Squamous odontogenic tumor (SOT) is a relatively rare, benign, small (rarely > 1.5 cm in diameter), but locally infiltrative and occasionally aggressive odontogenic epithelial lesion that appears to have harmatomous and neoplastic characteristics [1]. SOT is often asymptomatic, although it can present with mildly painful gingival swelling or tooth mobility. Radiographically, SOT is usually visualized as an irregularly or triangularly shaped unilocular radiolucency associated with the lateral roots of teeth. We report a case of the squamous odontogenic tumor occurring in a 60-year-old female in the right posterior maxilla with unusual radiographic and clinical appearances.

Sialadenoma papilliferum (SP) is a rare tumor that develops from salivary glands. First described by Abrams and Finck, the tumor shows a papillary form. The most frequent location of this tumor is the palate. In this case, we report a 63 year old man with a lesion located at the right retromolar of the mandible which might have caused bone resorption. Among with this case report, this paper discuss the feature of this rare tumor. The cases were searched from the pubmed website (https://www.ncbi.nlm.nih.gov/pubmed/) using the keyword ‘sialadenoma papilliferum’. Out of total 65 cases 41 patients were male and 19 patients were female. 4 patients were under the age of 20, 4 patients were between 21 and 40, 25 patients were between 41 and 60, 23 patients were between 61 and 80 and 4 patients were over 81 years old. The number of patients with the size of the lesion less than 1cm were 23, 16 patients had the size of 1cm to 2cm and 8 patients lesion were larger than 2cm. 22 lesions were located at the hard palate, 2 were at the soft palate, 6 were at the junction of hard and soft palate, 8 were at the buccal mucosa, 1 was at the upper lip mucosa, 3 were at the retromolar pad, 2 were at the tongue, 4 were at the parotid gland, 2 were at the floor of mouth, 1 was at the faucial pillar, 3 were at the bronchus, 1 was at the esophagus, 2 were at the nasopharynx, 1 was at the nasal septum, 1 was at the lung, 1was at the nasal cavity. In this case the lesion was found at an unusual location and although SP is known to be a benign tumor it may present bone resorption and have malignant characteristics.

Ameloblastoma is an odontogenic tumor characterized by various sites of metastasis, malignant transformation, and a high recurrence rate over time. Ameloblastic carcinoma(AC) is the term reserved for an ameloblastoma with histologic evidence of malignancy in the primary tumor. AC is classified into two types: most ACs occur de novo, and only few cases of malignant transformation of ameloblastoma become apparent. Here, we report a case of AC, arising from recurrent acanthomatous ameloblastoma on the maxillary sinus, in a 60-year-old male patient. The mass was first diagnosed as acanthomatous ameloblastoma; subsequently, surgical curettage was performed thrice while partial maxillectomy was performed twice. On the fifth recurrence, the tumor was identified as AC.

Intravascular papillary endothelial hyperplasia (IPEH) is an unusual reactive benign lesion of vascular origin caused by endothelial cell proliferation, which rarely occurs in oral cavity. IPEH appears in various forms because it has non-specific clinical presentation, so it can be misdiagnosed as a malignant lesion.Therefore, it is important to make a differential diagnosis by understanding the characteristics of this lesion.We report a case of IPEH in a 22-year-old Korean female patient, discussing about differential diagnosis and treatment. This report presents review of literature and describes a case of IPEH.
