Objective: Morphometric and morphological evaluation of the mandibular condyle in adults and to identify its correlation with skeletal malocclusion patterns. Methods: Cone-beam computed tomography scans of 135 adult patients were used in this study and classified into groups according to four criteria: (1) sex (male and female); (2) sagittal skeletal discrepancy (Class I, Class II, and Class III); (3) vertical skeletal discrepancy (hyperdivergent, normodivergent, and hypodivergent); and age (group 1 ≤ 20 years, 21 ≤ group 2 < 30, and group 3 ≥ 30 years). The morphometrical variables were mandibular condyle height and width, and the morphological variable was the mandibular condyle shape in coronal and sagittal sections. Three-dimensional standard tessellation language files were created using itk-snap (open-source software), and measurements were performed using Meshmixer (open-source software). Results: The mandibular condyle height was significantly greater (p < 0.05) in patients with class III malocclusion than in those with class I or II malocclusion; the mandibular condyle width was not significantly different among different sexes, age groups, and sagittal and vertical malocclusions. There were no statistical associations between various mandibular condyle shapes and the sexes, age groups, and skeletal malocclusions. Conclusions: The condylar height was greatest in patients with class III malocclusion. The condylar height and width were greater among males than in females. The mandibular condyle shapes observed in sagittal and coronal sections did not affect the skeletal malocclusion patterns.

Background: The establishment of a strategy for the reduction and prevention of oral disease, a global pervasive disease, is considered one of the important national health policy strategies. In Korea, the 5th Comprehensive National Health Promotion Plan is currently in progress, but there is insufficient research on the transition process or improvement direction in the field of oral health. Methods: Changes in Comprehensive National Health Promotion Plan's Oral health sector in three countries were compared, and the direction of the three countries (Korea, the United States, and Canada) in accordance with the recent Oral health paradigm was confirmed. In this study, we reviewed the existing literature using the narrative review method to draw implications for strategies and directions for oral health promotion in Korea. Results: In Korea, the oral health promotion strategy is included in the 5th Comprehensive National Health Promotion Plan, and the project is being led by the government. The United States prepared a national-led oral health promotion strategy and suggested multi-disciplinary cooperation to improve overall oral health and reduce the oral health inequality. For more active intervention, Canada established an oral health-related department and assigned experts, while emphasizing cooperation between the government and the private sector. Conclusion: As a result of this study, Korea is also making efforts to improve oral health, but more active government intervention is needed to reduce the inequality in oral health by population group. To this end, it is necessary to establish a strong multi-sectoral cooperation system and prepare a strategy for implementation.

The purpose of this study was to assess the level of awareness regarding the relationship between systemic diseases and oral health and the importance of education related to this association among dental patients, as well as to identify factors that affect the awareness of the relationship and the perceived need for education. This study was conducted from June 2016 to February 2017. Subjects of this study included outpatients (20-60 years old) from a dental clinic, and only patients who agreed to the survey were included. A total of 110 subjects were included, but the final analysis was based on 92 questionnaires, excluding questionnaires that were inaccurate. Survey questionnaires were completed by self-report and face-to-face interviews with a dental hygienist. The questionnaires covered basic information, awareness of the association between general and oral health, and experience with, and need for education related to, this association. Among the subjects, 48.9% were aware of the association between systemic diseases and oral health. A total of 39.1% of subjects had received education regarding the relationship between systemic diseases and oral health. Subjects who visited dental clinics regularly were 3.94 times (95% confidence intervals [CI]: 1.21-12.84) more likely to be aware of the association between oral health and disease compared with subjects who made only irregular visits to dental clinics. In addition, experience or education was significantly associated with awareness of the relationship between oral health and disease (odds ratio [OR]: 4.64, 95% CI: 1.54-13.93) and the need for education (OR: 3.98, 95% CI: 1.20-13.12). Thus, the dental professionals should provide education on the relationship between oral health and systemic disease in dental clinics to improve patients' awareness and oral health behaviors. These results can be used to strengthen education in the dental clinic.

Objectives : Targeting Korean adults, the food pattern are grasped. And, its correlation with oral disease is analyzed. In order to offer basic data to developing the nutritional policy and nutritional program for the future prevention from oral disease, a research was conducted by utilizing the Korean National Health and Nutrition Examination Survey 2005(the 3rd term). Methods : The subjects in this study were 6,526 adults in more than fully 19 years among 9,047 persons who participated in the food intake survey out of those who completed the health interview survey. The statistical analysis was analyzed by using SPSS 12.0 program. Results : 1. As a result of Group Analyzing was indicated to dangerous-type food pattern and protection-type food pattern. 2. As a result of analyzing the answers for having dental caries in the annually personal recognition was indicated to be high in the dangerous-type food pattern, and had not the statistically significant difference. 3. As a result of analyzing the answers for having periodontal disease in the annually personal recognition was indicated to be high in the dangerous-type food pattern, and had the statistically significant difference(p<0.05). 4. As a result of analyzing the food pattern factors that have influence upon both major oral illnesses in the annually personal recognition, the person, who has the dangerous-type food pattern, had high risk level of the periodontal disease in the annually personal recognition. Conclusions : In the above results, as a result of surveying and analyzing importance of the food pattern in the incidence of both major oral illnesses, it is considered that there will be necessity of continuing to research into developing the nutritional policy and nutritional program in order to prevent oral illness in the future.

Objectives : The purpose of this study was to analyze the status of oral health in relation to the acknowledgement of oral health trouble and oral health habits. Methods : This study was conducted after IRB was received, on 273 patients who had received health screenings between October-1, 2014 and January-31, 2015 at a general hospital in Busan. Results : Regarding the status of oral health in relation to the acknowledgement of oral health trouble, the rates of dental caries and periodontal disease were higher when the patients knew the reasons for trouble about the oral hygiene. With regard to oral health habits, our results showed that the more frequently the patients ate sugary snacks per day, the probability of experiencing periodontal disease was higher than for the patients who did not eat sugary snacks. Our results also, showed that the occurrence of dental caries is very much dependent upon whether a patient had experienced education on toothbrushing. Conclusions : Patients need to become more aware of their oral health through education. A program that emphasizes the importance of preventive oral health behaviors and the maintenance of correct oral health behavior should be developed.

Cemento-osseous dysplasia occurs in the tooth bearing areas of the jaws and is probably the most common fibro-osseous manifestation. They are usually classified into three main groups according to their extent and radiographic appearance: periapical (surrounds the periapical region of teeth and are bilateral), focal (single lesion) and florid (scleroticsymmetrical masses) cemental-osseous dysplasias. Florid cemento-osseous dysplasia clearly appears to be a form of bone and cemental dysplasia that is limited to the jaws. Patients do not have laboratory or radiologic evidence of bone disease in other parts of the skeleton. For asymptomatic patients, the best management consists of regular recall examinations with prophylaxis and the reinforcement of good home hygiene care to control periodontal disease and prevent tooth loss. The treatment of symptomatic patients is more difficult. At this stage, there is an inflammatory component caused by the disease and the process is basically a chronic osteomyelitis involving dysplastic bone and cementum. Antibiotics might be suggested, but are not always effective. Two cases of florid cemento-osseous dysplasia diagnosed in two Korean females are reported with a review of the relevant literature.

Leukemia is a malignant disease characterized by uncontrolled clonal proliferation of white blood cells. It is classified depending on clinical course of disease (acute or chronic) and the primary hematopoietic cell line affected (myeloid or lymphoid). Leukemia is often associated with orofacial manifestations, such as oral bleeding, petechiae, oral ulceration, gingival enlargement, mucosal pallor and mental nerve neuropathy. However, trismus has been rarely reported as a sign of leukemia. We present a case of trismus caused by acute lymphoblastic leukemia and emphasize the importance of orofacial manifestations in the early diagnosis of leukemia.

Leukemia is a hematological malignant disease with various clinical symptoms. Due to the fatal nature of the disease, early detection is important. Oral manifestations include ulcers and gingival enlargement with bleeding. Moreover, myeloid sarcoma or opportunistic infections may also occur. This report introduces a 31-year-old male presenting with generalized gingival enlargement with bleeding and another 81-year-old female with neoplasm on the left retromolar area. Both were diagnosed as acute monocytic leukemia. These cases implicate that gingival enlargement or mucosal lesion in the oral cavity may represent underlying systemic diseases. Related to this, it has to be reminded that making timely diagnosis and referral according to the clinical findings is crucial.
