Lameness of front limbs or hind limbs was occurred in German Shepherd dogs firm one brood bitch between 5 and 6 months of age. Physic81 examinations revealed pain associated with deep palpation of the affected area(u1nar, humerus, tibia, etc). But, no significant result was found for the clinical test including complete blood test and so oa Radiographic examination showed an increased radiopacity in the region of the nutrient foremen. Panosteitis was diagnosed on the basis of breed age, clinical signs and radiographic signs.

The system of Oral and Maxillofacial Radiology education, radiographic equipments and oral health care were evaluated in Korea. The objectives, the length, curriculum guidelines, instructional method and teaching means for undergraduate, and postgraduate education in 9 dental college were described. To investigate the radiographic ewuipments, surveys were received from 6 Dental College Hospitals(DCH), 23 Dental Hospitals(DH) and 373 Dental Clinics(DC). And the results of oral health care were obtained from the surveys of Kyunghee Dental College Hospital(KDCH), 14 Dental Hospital Hospitals and 52 Dental Clinics.

Traumatic bone cyst is known as a symptomless, radiolucent bony les ion incidentally found during routine radiographic examinations. The main characters of traumatic bone cyst are asymptomatic and unicystic radiolucent bony lesion with vital tooth. This case is a confusing case of a traumatic bone cyst with sudden gingival swelling and appearance like a periapical abscess. After surgical exploration and drainage, clinical and radiographic examination showed bony healing with pulpal vitality preserved after 7 months postoperatively.

The aim of this study was to investigate the effect of third molar extraction on the periodontal status of the adjacent second molar. A total of 61 second molars in 31 adult periodontitis patients were examined. Among them, 27 second molars without adjacent third molars were included in the test group, and 34 second molars with third molar were included in the control group. Clinical parameters including plaque index, gingival index, and pocket depth and radiographic bone loss were measured around the second molar both in test and control group. The result showed that: (1) the mean plaque index and gingival index of control group were higher than these of the test group but the difference was not statistically significant, (2) the mean pocket depth of the control group was higher than the test group significantly at distal and buccal surface, (3) radiographic hone loss was greater in control group than test group significantly, (4) in Pearson correlation analysis between the age of extraction and radiographic bone loss in the test group, a positive relationship was shown(p<0.01). Within limitation of this study, it may be concluded that third molar extraction in periodontitis patients showed an improvement in periodontal status in contrast the patients group having third molar, therefore earlier a removal of third molar may minimize radiographic hone loss of the adjacent second molar.

Purpose: To investigate the relationship between classification based on simple radiographic findings and arthroscopic findings of the cartilage lesions in medial degenerative arthritis of the ankle joint. Materials and Methods: We studied 41 ankles of 36 patients with asymmetrical narrowing of the medial joint space. Degenerative arthritis following fracture and those with generalized arthritic disease were excluded, but those with a history of ankle sprain were included. Standing radiographs of all patients were graded according to the Takakura classification and the Kellgren-Lawrence (K/L) classification. Arthroscopic findings were classified according to the depth, width, and anteroposterior dimension of articular cartilage damage. Results: According to the Takakura classification, 29 ankles were classified as stage II, 7 cases as stage IIIA and 2 cases as stage IIIB. According to our classification of arthroscopic findings of 29 ankles in stage II, 1 ankle was graded as Grade I, 3 ankles as grade II, 10 ankles as grade III, and 15 ankles as grade IV. Spearman correlation coefficient between Takakura classification and arthroscopic classification was 0.342 (P=0.028), and coefficient between K/L classification and arthroscopic classification was 0.480 (P=0.001). Conclusion: Degenerative changes of the articular cartilage are more advanced than radiographic findings in many patients with ankle degenerative arthritis with asymmetrical narrowing of medial joint space. Therefore, we conclude that more aggressive effort should be made for correct diagnosis and treatment of degenerative arthritis.
