The $Papillon-Lef\`{e}vre$ Syndrome(PLS), a disease with autosomal recessive inheritance, is characterized by diffuse hyperkeratosis of the palms and soles, mostly prepubertal periodontitis and premature loss of primary and permanent dentition. The etiology of the destruction of periodontal tissues has not been completely clarified. In recent years, two main factors are suggested to be responsible for tooth loss ; firstly, the presence of gram negative microorganisms in the periodontal pockets of the patients. The other factor suggested is cellular deficiency in chemotaxic and phagocytic function of neutrophylic granulocytes. Resent data suggestes that mechanical debridement in conjunction with antibiotic therapy may be successful in periodontal management of $Papillon-Lef\`{e}vre$ Syndrome, particularly if administered early. In this study, a $Papillon-Lef\`{e}vre$ Syndrome patient was studied clinically, radiologically, histopathologically and microbiologically. 5 years female patient with gingival swelling and destruction of periodontal structure on the whole dentition were examined and palmar and plantar hyperkeratosis were can be seen. On microbiological analysis, Actinobacillus actino-mycetemcomitans was performed. Concurrently, the children recieved extraction of maxillary anterior teeth and construction of removable prosthetis. The combination of professional oral hygiene care and antibiotic therapy improved the dermatologic and periodontal condition.

Objectives: The purpose of this study was to compare the dental treatment needs of workers depending on their shifts and working patterns. Methods: Only workers aged 15 or older according to the $6^{th}$ Korea National Health and Nutrition Examination Survey (2013-2015) were considered eligible. A total of 9,092 people who responded to health surveys and completed oral examinations and interviews were selected for the study. Statistical analysis was carried out by the complex samples general linear model. Results: As the daytime workers' age increased, the requirement for restorative treatment decreased. In contrast, the requirement for tooth extraction caused by dental caries and periodontal disease increased. As the evening shift workers' age increased, the requirement for restorative treatment decreased. In the case of shift workers, the requirement for restorative treatment was lowest in those aged 50-64 years and highest in those aged 30-49 years. In the case of smokers; the daytime workers required a higher amount of restorative treatment, pulpal treatment, and tooth extraction due to dental caries and periodontal disease; the night shift workers required a higher amount of restorative treatment; and the shift workers required a higher amount of tooth extraction caused by periodontal disease. The results of comparing the dental treatment needs depending on working patterns were: the need for restorative treatment was higher in night shift workers (0.377) than in shift workers (0.245); the requirement for pulpal and restorative treatment was higher in daytime workers (0.055) than in night shift workers (0.010); requirement for tooth extraction due to periodontal disease was higher in night shift workers (0.060) than in evening shift workers (0.012). Conclusions: There are differences in dental treatment needs depending on the workers' working patterns. Collective oral health care is needed at workplaces to promote the workers' oral health.

Purpose: Systemic health has a profound effect on dental treatment. The aim of this study was to evaluate peri-implant bone loss and health screening data to discover factors that may influence peri-implant diseases. Methods: This study analyzed the panoramic X-rays of patients undergoing health screenings at the Health Promotion Center at Seoul St. Mary's Hospital in 2018, to investigate the relationship between laboratory test results and dental data. The patients' physical data, such as height, weight, blood pressure, hematological and urine analysis data, smoking habits, number of remaining teeth, alveolar bone level, number of implants, and degree of bone loss around the implant, were analyzed for correlations. Their associations with glycated hemoglobin, glucose, blood urea nitrogen (BUN), creatinine, and severity of periodontitis were evaluated using univariate and multivariate regression analysis. Results: In total, 2,264 patients opted in for dental health examinations, of whom 752 (33.2%) had undergone dental implant treatment. These 752 patients had a total of 2,658 implants, and 129 (17.1%) had 1 or more implants with peri-implant bone loss of 2 mm or more. The number of these implants was 204 (7%). Body mass index and smoking were not correlated with peri-implant bone loss. Stepwise multivariate regression analysis revealed that the severity of periodontal bone loss (moderate bone loss: odds ratio [OR], 3.154; 95% confidence interval [CI], 1.175-8.475 and severe bone loss: OR, 7.751; 95% CI, 3.003-20) and BUN (OR, 1.082; 95% CI, 1.027-1.141) showed statistically significant predictive value. The severity of periodontitis showed greater predictive value than the biochemical parameters of blood glucose, renal function, and liver function. Conclusions: The results of this study showed that periodontal bone loss was a predictor of peri-implant bone loss, suggesting that periodontal disease should be controlled before dental treatment. Diligent maintenance care is recommended for patients with moderate to severe periodontal bone loss.

The long term success of periodontal treatment is dependent upon the effectiveness of the main-tenance care program after active treatment. The purpose of this study was to evaluate whether nutraceutical containing PRF-K2 as natural product from plant and seaweed has beneficial effects on clinical parameters, gingival crevicular fluid (GCF) volume and GCF cytokine levels during main- tenance phase after periodontal treatment. Among the generally healthy and non-smoking. moderate to severe chronic periodontitis patients during maintenance phase in Department of Periodontics, Chonnam National University Hospital, twenty eight patients took nutraceutical containing PRF-K2 (Oscotec Inc. Cheonan, Korea) for 3 months as experimental group and sixteen patients received only maintenance care as control group. Clinical examination and GCF collection were performed at baseline, 1, 2 and 3 months of experiment. Total amounts and concentrations of GCF IL-1{\beta}, IL-1ra and $PGE_2$ were evaluated using ELISA kit. In probing pocket depth, experimental group showed the tendency of more reduction than control group after 3 months of experiment. Sulcus bleeding index (SBI) and GCF volume were significantly decreased in experimental group(p<0.05), whereas they were increased in control group. GCF IL-1{\beta} level tended to decrease in both experimental and control group and IL-1ra concentration tended to increase in experimental group and to decrease in control group. IL-1ra/IL-1{\beta} ratio tended to increase in experimental group and to decrease in control group during experimental period. GCF $PGE_2$ amount did not show any change in experimental group and tended to increase in control group. These results suggest that nutraceutical supplement which contain PRF-K2 could improve perio-dontal condition during maintenance phase after periodontal therapy.

Objectives: This study was conducted to assess dental health states of disabled people and analyze association between perception and awareness toward dental health and dental health status. Methods: The survey was performed from June 25 through October 30, 2004. A total of 548 disabled people participated in the study with details of 419 living in eight residential care centers located in Gyeongsangbuk-do and 129 children from a special school and two day-care centers. All subjects underwent oral examination and surveyed through a questionnaire. Parents of 129 children with disabilities were also surveyed through a separate questionnaire. Results: The dental caries experience rate was 82.1% of total 548 subjects. By age, those in their 20s experienced a high rate of dental caries with 87.5%. By educational level, those with a middle school education experienced a high dental caries rate with 91.8% (p<0.05). Of total subjects who experienced dental caries, 78.9% had experience in dental caries treatment. By age, those in their 10s showed a high rate of dental caries treatment with 87.4%(p<0.05). By educational level, those with a high school education showed a high rate of dental caries treatment with 87.7%(p<0.05). Those in residential care centers had a high rate of dental caries treatment with 82.1%, which is significantly higher than 68.8% of those who used day-care centers. A tooth extraction rate was 38.0% of total subjects. Those in their 40s had a higher rate of tooth extraction(p<0.01). Those in residental care centers had a significantly higher rate of extraction with 43.4%, compared with 20.2% of those in day-care centers. Of total subjects, 61.5% had plaque. A high rate of plaque formation was observed in those in their 40s(92.0%), those with a high school education(84.0%) and those with multiple disabilities(77.8%)(p<0.01). Among total subjects, 47.6% maintained healthy periodontal tissue. Those in their 40s and those with multiple disabilities had diseased periodontal tissue(p<0.01). Of 129 disabled children, 43.8% had plaque with parents who were not oral health-conscious while 18.6% had plaque with parents who were oral health-conscious, showing a significant difference(p<0.05) Conclusion: The results of the study suggest the need for educating parents with disabled children about oral health and strengthening programs for oral health for teachers working at special schools and day-care centers.

과학기술이 발전함에 따라 치주과학 영역에서도 1960년 이후 1980년대에 걸쳐 괄목할 만한 학문적 발전이 이루어졌으며 1990년에는 이에 의거한 치주질환의 예방 및 조절방법이 개발되어 사용되고 있다. 미래의 치주처치전략은 대상 지역의 특성과 보건환경에 따라 달라지므로 여기에서는 한국내 치주치료요구도와 치주치료 담당 일반치과의와 치주전문의의 수, 처치 내용에 대해 점검하고 현재의 치주처치 추세를 검토한 후 향후의 치료전략에 대해 언급하고자 한다. 1980년도 역학조사에 의하면 전체 인구의 82%가 치주질환(치은염+치주염), 35세 성인 인구의 30-40%가량이 치주염에 이환되어 있고 15세 청소년 인구중 0.1%가 유년형치주염에 이환되고 있다. 평균 수명이 증가하면서 65세 이상의 노년층도 전인구의 6%(성인 50%), 2000년도에는 6.9%(성인 52%)로 증가하고 치아보유율도 증가하므로 치주질환 치료요구도는 상승하리라 전망된다. 현재 한국내 치주전공 과정을 거친 치과의사는 약 780인 정도이다, 1996년 류의 연구에 의하면 이들도 대부분 일반치과의(개원의, 공증보건의 포함)로서 진료하고 있으며 의료보험하에서의 치주치료의 비중은 매우 낮다(4.66%). 포괄적 치주적 검사도 보편적이지 않고 대학병원급의 극히 일부에서만 이행되고 있는 실정이다. 향후의 치주질환이 처치전략에는 의료보험 운용시 치주적 배려와 간편한 치주검사과정을 통한 조기진단 및 조기치료, 진행기질환 및 난치성질환자의 치주전문으로의 의뢰가 포함될 것이며 각 환자에게는 개별적이며 임상시험 결과에 근거하는 evidence-based approach에 의한 치료선정 과정이 활용되리라 전망한다.

Objectives : The aim of the trial was to study the effect of plaque control(tooth brushing instruction) for oral health improvement on periodontitis patients. Methods : 30 patients(35~65 years) with advanced periodontal disease were subjected to a baseline examination including assessment of oral hygiene status(O'leary index), gingival condition(bleeding). the assessment were repeated after 2, 4, 6 weeks. cognitive, behavioral and clinical outcomes were assessed in the primary care setting by questionnaire and clinical oral examination. Results : The oral hygiene status expressed as the individual mean percentage of tooth surfaces with plaque 59.3% at baseline and 21.2% after 6 weeks(p<0.001). The gingival bleeding status expressed as the individual mean point of interdental papilla 3.8 at baseline and 1.9 after 6 weeks(p<0.001). Also, the patients self-assessment about correct tooth brushing behavior was 3.9(5-point likert scales), satisfaction of plan practices 4.1(5-point likert scales), efficacy of tooth brushing instruction 8.7(10-point likert scales). Patients wanted to continuous participation. Conclusions : A verification of effect after individualized oral health instruction and repeated dental plaque control represented to significance on plaque control score, oral care practice and oral health recognition. The important oral care step against periodontal disease is to establish good oral health habits. Also, oral health behavior recognition is more important for the practice of oral health. Therefore professional plaque control and tooth brushing instruction absolutely need in improving oral health.
