We investigated 52 cases of 42 patients who were diagnosed as odontogenic keratocyst in the department of Oral and maxillofacial Surgery of Kyungpook National University from 2006 to 2008, and following results were obtained. 1. Among 52 cases of OKCs, all cases were parakeratinzied. 2. Among 52 cases of OKCs, 42 cases were type I, 9 cases were type II and 1 case was type V. 3. Among 52 cases of OKCs, there were bud-like proliferation of basal cell layer on connective tissue area on 10 cases, satellite cysts on overlying oral mucosa or connective tissue area on 6 cases and rests of epithelium on connective tissue area on 6 cases. 4. Among 52 cases of OKCs, there were focal inflammation on the epithelium of the OKCs on 6 cases and diffuse inflammation on 8 cases. 5. Among 52 cases of OKCs, cytokeratin-10 was expressioned on superficial and intermediate layer on all cases. Accordingly, the presence or absence of cytokeration-10 on the epithelium of the cyst will be good differential diagnosis of between OKC and dentigerous cyst.

The purpose of this study was to investigate the effects of “H” fermented food product of Bayo Co., Ltd., on human health and intestinal microflora, and their relationships. Waist size was measured for the 90 applicants from Seongsangu, Changwon before and after taking the “H” product for 15 days. They were also surveyed to identify the demographic, physical and personal characteristics, and health characteristics. Microbial community structures were analyzed by a pyrosequencing method for the stools collected for some representative applicants. The greatest waist size reduction of 3.3 cm observed in the 40s. Overall satisfaction for the formula food was above average. Especially relief of atopy symptoms was highest in the 20s, constipation relief in the 40s, and digestion promotion in the 60s. In addition, the beneficial enteric bacteria (Faecalibacterium sp., Bifidobacterium sp. and Alistipes sp.) appeared to increase overall after the ingestion by all these ages. The microbial community structure of the 60s was significantly different from those of the 20s and 40s. Ingestion of this fermented food appeared to cause beneficial microbial community structures that could maintain a good intestinal health. Development of various intestinal health indicators based on this study will greatly contribute to the development and utilization of customized functional fermented foods.

We sought to evaluate the relationship between the mandibular canal and impacted mandibular third molars by using dental cone beam computed tomograph(CBCT) for third molar surgery. A total of 111 patients(177 teeth) offered the images through CBCT and panoramic radiography for the extraction of the mandibular third molars. In CBCT, the accurate relationship between the third molar and the mandibular canal were evaluated. In panoramic radiographies, we evaluated the impacted level and superimposition sign of the mandibular third molar with the mandibular canal, and also, the radiopacity of the white line in the canal. Data were statistically analyzed and estimated by $X^2$-test. In CBCT finding, high prevalence of contact between the mandibular canal and roots occured in the deep impacted third molars, narrowing mandibular canals, bending mandibular canals and cases where the radiopacity of white line of canals were "absence" on panoramic images. It showed statistical significance (P<0.05). When evaluating the mandibular canal and the roots through the panoramic radiography for third molar extraction, it could be difficult to diagnosis accurately. Thus, it is required to have an accurate diagnostic approach through CBCT that could evaluated the location between mandibular canal and root.

This study aimed to verify the results of emotional analysis with respect to canine behavior as reported in the existing animal behavior field based on the dog vestibular emotional reflex (VER) principle, and to evaluate humans and animals based on empathy gained through true communication rather than human-centered interpretation. A total of 200 canines were divided into non-daily and daily situation groups (n=100 each). To assess the psychological and emotional state of each group, these changes were applied to the principle of VER, and six measurement values were selected: positive emotion (balance and energy), negative emotion (tension/anxiety and stress), and body condition (inhibition and neuroticism). The results showed a statistically significant difference (p<0.05) in positive emotions, negative emotions, and body conditions between the two groups. In addition, balance, energy, tension/anxiety, inhibition, and neuroticism were higher in the non-daily situation group than in the daily situation group, with an exception for stress. Compared with the canine daily situation groups, canine in the non-daily situation groups instinctively observed their surroundings to cope with possible threats, had decreased concentration, and elevated vitals due to high-intensity anxiety. This can be perceived as a state of immediate reaction to possible situations/threats. In conclusion, it was confirmed through Vibra Image technology that canine instability mainly affects three factors: positive emotion, negative emotion, and physical condition.
