Halitosis, defined as an unpleasant oral odor, is a commonly experienced condition with a variety of etiological factors and may cause a significant social or psychological handicap to those suffering from it, In most cases, halitosis originates within the oral cavity itself and patients with periodontal disease often suffer from oral malodor, The most common cause of this disease is related to microbiota which reside on the tongue and in the periodontal pocket, This study was undertaken to examine the effect of full mouth disinfection including tongue scraping on oral malodor in a group of patients with chronic periodontitis, The relationship between halitosis and oral health status was also investigated, The volatile sulfur compounds (VSC) scores were significantly correlated with Plaque Index, Bleeding Index, pocket depth, and tongue coating score, The organoleptic ratings were significantly associated with Plaque Index, Bleeding Index. and tongue coating score, The VSC scores and organoleptic ratings correlated strongly with each other. Full mouth disinfection resulted in a significant reduction in the VSC scores. organoleptic ratings, and self-perception of malodor up to 12 weeks, This study indicates that in patients with chronic periodontitis. a full mouth disinfection including tongue scraping has a significant effect in the treatment of oral malodor.

Objectives: Chronic periodontitis is a common inflammatory disease of the oral cavity that causes destruction of periodontal tissues and bone around the teeth. Sclerostin is a protein encoded by the SOST gene. In this study, gingival crevicular fluid (GCF) levels of sclerostin in patients with chronic periodontitis were compared with those of healthy subjects. Materials and Methods: In this case-control study, a total of 40 subjects were enrolled and divided into the healthy group (n=23) and chronic periodontitis group (n=17). GCF samples were collected, and the concentration of sclerostin was evaluated using enzyme-linked immunosorbent assay. Comparison of significance between groups was assessed using Mann-Whitney U test. Results: Sclerostin concentration was significantly higher in the chronic periodontitis group compared with the healthy group (P<0.005). Conclusion: Despite the limitations of this study, sclerostin can be a possible marker for assessment of periodontal health status.

Korean society is experiencing rapid growth due to industrialization and urbanization, and the aging of population is emerging. Degradation of the masticatory muscle due to aging and reduction of the number of mastications causes dry mouth syndrome with decreased saliva in the elderly. Changes in the amount and composition of saliva cause various oral diseases, especially, periodontal disease is closely related to the microorganisms that form the plaque. In the elderly education, stimulation saliva was collected at the first visit and the last visit to observe changes in microorganisms in the oral cavity. For the collection of the probes, the paraffin wax was chewed for 5 minutes. The samples were immediately refrigerated in a 50 cc plastic tube and then stored at $-20^{\circ}C$ until the next use. The subjects of this study were the elderly people aged 65 years or older, and the study was conducted on 16 persons, 3 males and 13 females. The distribution of saliva microorganisms according to rolling brushing method showed significant difference in all three groups (Aa & Red complex, Orange complex and Green complex) before and after the education. In the group who answered that they had dentures, it was confirmed that the amount of microorganisms before and after education was significantly reduced in all three groups. There was a significant decrease in the amount of microorganisms in the Aa & Red complex and Orange complex group in the case of hypertension related to systemic disease. In conclusion, the higher the interest of oral health and general health of the subjects, the more effective the education.

Background: Oral cavity cancers, the second most common type in India, are responsible for 10% of the overall cancer burden. With a recurrence rate of 30% to 40% and a 5-year survival rate of 50%, these malignancies account for substantial morbidity and mortality. Despite advances in treatment modalities, survival rates following treatment completion have not improved significantly. The present study aimed to establish specific epidemiological and pathological factors responsible for recurrence after treatment completion in buccal mucosa cancers. Methods: A retrospective analysis of the data of 116 patients treated for biopsy-proven cancers of the buccal mucosa was undertaken 1 year after treatment completion. Factors such as age, sex, education, lymphovascular invasion, extranodal extension (ENE), perineural invasion, depth of invasion, and pathological margin status were compared between patients who presented with recurrence and those who did not. Statistical significance was set at p< 0.05. Results: Of the 116 patients, 40 (34.5%) developed a recurrent disease within 1 year. The mean age of the study population was 43.3 years, and males constituted 91.4% of the included patients. Ipsilateral buccal mucosa was the commonest site of disease recurrence. Neck node metastasis, ENE, and margins of resection < 5 mm were significantly related to the recurrence of disease. However, surprisingly, lymphovascular invasion, perineural invasion, and depth of invasion > 10 mm did not show statistically significant associations. Conclusion: Neck node metastasis, ENE, and margins of resection < 5 mm were the histopathological factors associated with recurrence in cancers of the buccal mucosa.

The purpose of this study was to examine the actual dental hygiene status of workers in cement industry in an effort to serve as a basis for enhancing their dental hygiene. The subjects in this study were 420 laborers from the cities of Curi, Donghae and Samcheok who handled cement. As a result of conducting a survey, the following findings were given : l. The workers investigated found their working environment satisfactory, getting a mean score of 323. They also expressed a high job satisfaction with a mean score of 333. 2. They didn't have a big interest in oral health. By age group, those who were aged between 36 and 40, or who cared less about health management, showed a higher interest in oral health. Besides, the laborers who kept smoking for a longer period, or who drunk more, expressed greater interest. 3. The toothbrushing method was considered most important for periodontal health, by 45.0% of the workers, and the next most crucial one was regular dental examination, followed by refraining from smoking and staying away from sweet food in the order named. 4. Concerning daily mean toothbrushing frequency, 455% brushed their teeth three times a day on the average. More than half them didn't pay enough attention to toothbrushing. 5. Regarding scaling, the large number of the workers, 42.4%, had no experience to get their teeth scaled, 37.6%, the greatest percentage, didn't have their teeth scaled because it seemed to make their teeth painful or cold. 6. As fororal health education experience, 67.6%, the great number of them, had no experience to receive dental health education. The above-mentioned findings suggest that the cement-related workers generally neglected dental health management. They should be encouraged to correct their wrong oral health knowledge or habit to make their oral cavity more healthy. To make it happen, it's required to provide oral health education and promote organized dental health projects.

Purpose: This article tried to find the relations between periodontal diseases, body mass index and clinical level for Korean adults over the age of 19, utilizing data of the 6th national nutrition survey. Methods: In the collected data, 14,940 adults aged 19 years or older were included in the study to determine the relationship between the general health status of Korean adults and periodontal disease. Results: As the result, 28.6% of Korean adults had periodontal diseases, there were significant differences depending on gender, age, smoking, residential aria, education level, body mass index, HDL-cholesterol, leukocyte value and fasting blood sugar. When general factors were controlled for multiple logistic regression analysis, there was significance as BMI cross rate was 1.029(95% C1, 1.007-1.051). HDL-cholesterol cross rate was 0.989(95% C1, 0.980-0.999), leukocyte cross rate was 1.086(95% C1, 1.040-1.134) and fasting bloody sugar cross rate was 1.006(95% C1, 1.003-1.009), so there were significance. In conclusion, there was a significance relation between periodontal diseases, body mass index, HDL-cholesterol and fasting bloody sugar. Conclusion: Based on the results of this study, oral health education should be used to manage and maintain healthy oral cavity by improving periodontal disease management and awareness. In addition, it will be necessary to develop periodic oral examinations and age - specific oral health education programs, and it can be used as a basic data for public oral health plan.

본 연구팀이 개발한 신개념 강내형 치과 진단 장치에서 촬영한 X선 치아영상으로부터 치아 우식증을 조기 단계에서 판별하고 치과의사의 정확한 진단을 돕기 위해서 병변진단 보조시스템인 치아 와동 자동 검출 프로그램을 개발하고자 하였다. 치아 와동 자동 검출 시스템을 구성하고 있는 기본 알고리즘은 치아 와동과 정상 치아를 구분 할 수 있는 영상분별 알고리즘과 치아 영상의 고유 특성 정보를 분석하고 이를 병변 검출에 적용할 수 있는 알고리즘으로 나눌 수가 있는데, 본 연구에서는 먼저, DRLSE 방법을 적용하여 병변과 정상치아 사이의 윤곽선 분할 성능을 테스트 하였다. 개발된 알고리즘의 와식 판별 성능을 테스트하기 위해서 다양한 형태의 와식을 포함하는 전치, 견치, 소구치 등의 7개의 치아팬텀을 제작하고 치아 와식 분별을 실시하였다. 총 14 개의 와식 중에 와식의 경계를 부분적으로 식별한 2개를 제외하고는 12개 와식의 경계를 정확하게 구별하여 개발된 자동 치아 병변 알고리즘의 가능성을 입증하였다. 그러나 실제 치아 와식의 형태는 개개인마다 다르고 복잡하기 때문에 무작위로 선택된 실제 치아에 적용하기 위해서는 보강된 알고리즘이 필요하다. 향후에는 치아에 대한 사전정보를 처리하고 적용하는 패턴 인식 혹은 기계학습 알고리즘을 추가하여 보다 효과적이고 정확한 병변 알고리즘으로 개선할 예정이다.

상악 중절치는 저작시 음식물을 찢거나 자르는 기능 외에도 심미적으로 중요한 기능을 하며 상악 악궁의 형태 및 얼굴의 형태와도 관계가 있다고 알려져 있다. 그리고 발음을 하는데 있어서도 전치부는 매우 중요한 역할을 한다. 예후가 불량한 치아의 일반적인 치료는 발거 후 공간 유지장치를 하는 것이다. 그러나 혼합치열기에 있어 상악 영구 중절치의 발거는 치조골의 흡수, 불량한 심미성, 발음과 저작의 문제 등 여러 가지 합병증을 일으킬 수 있다. 이러한 이유로 상악 전치부의 치료는 보존적으로 행해져야 한다. 예후가 불량한 상악 전치부의 치료시 고려해야 할 사항으로는 환아의 나이, 성장 잠재력, 교합 관계, 구강 위생상태, 경제력 그리고 환아의 치료에 대한 협조도 등이 있다. 본 증례는 짧은 치근으로 인해 치아의 동요도가 있어 상악 좌측 중절치의 예후가 불안정함에도 불구하고 치아를 발거하지 않고 치료를 통해 상악 좌측 중절치를 정상 위치로 배열하고 보존하였다. 짧은 치근과 치아 회전으로 인한 추가적인 치근 흡수와 치아 동요도 증가 등 예후가 불안정하였지만 환아의 심리적 안정성, 나이, 심미성 등을 고려하여 보존적인 치료 후 양호한 결과를 얻었기에 이를 보고하는 바이다.
