  • We have conducted a retrospective study of 224 patients with the diagnosis of oral and maxillofacial infection who had been treated between 1988 and 1999 at Gyeong-Sang National University Hospital. This study was aimed to furnish the data of oral and maxillofacial infection and to aid diagnosis and treatment. The most common fascial space involved, as determined by clinical, radiologic, and operative findings, were the submandibular space(39.4%). The most frequent cause of oral and maxillofacial infection was odontogenic 68.8%. In the odontogenic cause, dental caries was the most common cause. Two-hundred three patients required surgical drainage of the abscess. Seventeen patients needed tracheostomy for airway control. The overall mortality was 0.9% despite aggressive anti-microbial therapy and early surgical intervention. All other patients had an uneventful recovery without major complication except osteomyelitis case(6.0%). The combination of early radiologic diagnosis, effective antimicrobial therapy, and intensive surgical management contributed to the good prognosis.

  • Dental plaque is a film of microorganisms on the tooth surface that plays an important part in the development of caries and periodontal diseases. Streptococcus mutans (S. mutans) is present in almost all types of dental plaque. Teeth and their supporting structure, the gums (gingiva) are subjected to infection by S. mutans that causes cavities and pyorrhea which, if left untreated, can eventually lead to gingivitis. Various chemical agents have been evaluated over the years with respect to their antimicrobial effects in the oral cavity; however, all are associated with side effects that prohibit regular long-term use. The present study was designed to investigate the effect of Aralia continentalis (Araliaceae) extracts on the growth, acid production, adhesion, and insoluble glucan synthesis of S. mutans. The methanol extract of A. continentalis showed concentration dependent inhibitory activity against the growth and acid production of S. mutans, and produced significant inhibition at the concentration of 0.25, 0.5, 1, 2 and 4 mg/ml compared to the control group. The extracts markedly inhibited S. mutans adherence to HA treated with saliva, and cell adherence was repressed by more than 60% at the concentration of 0.25 mg/ml and complete inhibition was observed at the concentration of 4 mg/ml. On the activity of glucosyltransferase which synthesizes water insoluble glucan from sucrose, methanol extract of A. continentalis showed more than 10% inhibition over the concentration of 0.25 mg/ml. The synthesis of insoluble glucan was decreased in the presence of 0.25 - 4 mg/ml of the methanol extract of A. continentalis. Hence, we conclude that A. continentalis might be a candidate of anticaries agent.

  • The purpose of this study was to investigate the prevalence of dental caries, periodontal status, and self-perceived oral health status of students in juvenile protection education institutions. The subjects of this study were 342 adolescents aged 13-20 years detained in two juvenile protection education institutions located in Gyeonggi Province. The study involved an oral examination to record decayed, missing, filled teeth and index teeth with bleeding, calculus, or periodontal pocket, combined with a questionnaire to investigate self-perceived oral health status. The main findings are as follows. 1. When compared with the result of National oral health survey, the students detained had more decayed teeth, DMFT, and teeth with bleeding, calculus, and shallow pocket than general population of the same age. 2. Female students showed more DMFT, more teeth with healthy periodontium, and fewer teeth with shallow pocket than male students (p<0.05). 3. Female students perceived their health to be poorer than male students (p<0.05). A majority(79.2%) of detainee valued their oral health in their life. 4. A majority(71.5%) of detainee reported their dental anxiety, and more female adolescents showed dental anxiety than male adolescents(p<0.05).

  • Cow's milk and dairy products are elements of the human diet that could play an important role in improving human health. The macronutrients and micronutrients found in milk could supply the nutrients required to maintain human health. Among them, milk-derived bioactive peptides have been identified as potential ingredients found in health promoting functional foods. These bioactive peptides target diet-related chronic diseases, particularly non-communicable ones such as cardiovascular disease, diabetes and obesity. Additionally probiotics such as lactic acid bacteria (LAB) are can be considered live microorganisms that confer health benefits for the host-, when administered in adequate amounts. Further, the calcium, vitamin D, and protein content of milk and dairy products could play a role in proving bone health. The effect of milk and calcium on bone mineral density could prevent against fracture, osteoporosis and rickets. Furthermore, milk and dairy products also contain which factors that, which protect against dental caries (anti-cariogenic properties). This paper reviews the various nutritional functions of milk and dairy products in improving human health.

  • Objectives : Fluoridation of drinking water is known to decrease dental caries, particularly in children. However, the effects of fluoridated water on bone over several decades are still in controversy. To assess the risk of hip fracture related to water fluoridation, we evaluated the hip fracture-related hospitalizations of the elderly between a fluoridated city and non-fluoridated cities in Korea. Methods : Cheongju as a fluoridated area and Chungju, Chuncheon, Suwon, Wonju as non-fluoridated areas were chosen for the study. We established a database of hip fracture hospitalization episode based on the claims data submitted to the Health Insurance Review Agency from January 1995 to December 2002. The hip fracture hospitalization episodes that satisfied the conditions were those that occurred in patients over 65 years old, the injuries had a hip fracture code (ICD-9 820, ICD-10 S72) and the patients were hospitalized for at least 7days. A total of 80,558 cases of hip fracture hospitalization episodes were analyzed. Results : The admission rates for hip fracture increased with the age of the men and women in both a fluoridated city and the non-fluoridated cities (p<0.01). The relative risk of hip fracture increased significantly both for men and women as their age increased. However, any difference in the hip fracture admission rates was not consistently observed between the fluoridated city and the non-fluoridated cities. Conclusions : We cannot conclude that fluoridation of drinking water increases the risk of hip fracture in the elderly.

  • Osteomyelitis is an exhaustive disease whose main feature is an inflammation of inner part of bone, bone marrow. In oral and maxillofacial area, we have maxillary and mandibular osteomyelitis and the latter is dominant because of its impaired blood supply. The main cause of osteomyelitis is a bacterial infection and the ways of infections are by periapical odontogenic infection, fracture, post-operative complication, and periodontal disease. The predominant etiologic factor is periapical odontogenic infection mostly caused by advanced dental caries. It is generally believed that periodontal disease could be a cause of osteomyelitis. But periodontal disease is usually confined to the alveolar bone area and not extends to the underlying bone marrow. Accordingly periodontal infection per se rarely cause produce oseomyelitis. Even though osteomyeltis could be occurred by periodontal disease, its virulence of infection is milder than periapical odontogenic infection. So it usually provokes sclerosing or hyperplastic osteomyelitis rather than suppurative type. We had a case of suppurative osteomyelitis caused by periodontal disease and treated it with periodontal and oral and maxillofacial surgical method.

  • Background: This study aimed to investigate allergic rhinitis and the relationship between allergic diseases, such as asthma and allergic rhinitis, and dental caries and periodontal disease using the raw data from third year of the 6th Korean National Health and Nutrition Examination Survey. Methods: A total of 3,729 subjects aged over 30 years who underwent examination for allergic diseases and an oral health checkup were selected. The data were analyzed using SPSS IBM SPSS ver. 25.0 (IBM Corp., USA). Composite sample cross correlation and composite sample logistic regression analyses were performed using the composite sample general linear model. Results: On examining the socioeconomic characteristics of the subjects suffering from allergic disease and the relationship between allergic disease and oral health, allergic rhinitis was more frequently found in younger subjects with a higher level of education. Periodontal disease and dental caries were more frequent among female, older age groups, lower income earners, and subjects with a lower level of education (p<0.05). On examining the relationship between the oral health characteristics of the subject and allergic diseases and oral health, allergic rhinitis was more common in subjects with a good oral health status perception than those who answered "bad" to the oral health status question. The community periodontal index of treatment needs (CPITN) score was higher in subjects who answered "poor" to the oral health status question, lower frequency of brushing, and higher in subjects using secondary oral hygiene products; the decayed, missing and filled teeth (DMFT) index was higher in subjects with a perception of poor oral health status (p<0.05). The DMFT index was high in the asthma group, and the CPITN score was high in the group who answered "no" to allergic rhinitis. Conclusion: There is a relationship between asthma and allergic rhinitis and the DFMT index and CPITN score. Corresponding oral programs for allergic patients need to be developed.

  • When a tooth adjacent to implant has coronal damages caused by severe dental caries or fracture, the clinical crown lengthening by forced eruption makes it possible to get esthetic restoration due to the prevention of alveolar crestal bone resorption and loss of interdental papilla. A 54-years-old male patient wanted prosthetic treatment because his anterior 3 unit bridges had fallen out. A right maxillary central incisor showed mild dental caries but a right maxillary canine lost most clinical crowns. Forced eruption combined with a gingival fiberotomy of a right maxillary canine was performed for 1 month after the dental implant had been simultaneously placed with bone grafts on a right maxillary lateral incisor. About 5 months after implant placement, 2nd surgical operation was performed. The provisional restorations were adjusted to make esthetic gingival contour for 8 weeks. The porcelain fused gold restorations were fabricated and set. The patient was satisfied with the final restorations in esthetic and functional aspect.
