본 연구는 국민건강영양조사 제4기 자료를 이용하여 한국 성인에서 비타민 섭취와 치주염과의 관련성을 구명하고자 하였다. 국민건강영양조사 원시자료에서 건강조사와 구강검진 및 식이조사에 모두 참여한 19세 이상 성인 6,245명의 자료를 추출한 후 복합표본설계를 반영하기 위하여 가중치를 고려한 통계분석을 실시하였다. 대상자의 인구사회학적 특성, 전신건강상태와 행태, 구강건강상태와 행태 및 비타민 섭취 5분위에 따른 치주염 유병률의 차이를 ${\chi}^2$-검정을 이용하여 분석하였으며, 로지스틱 회귀분석을 이용하여 인구사회학적 특성, 전신건강상태와 행태 및 구강건강상태와 행태를 보정한 비타민 섭취와 치주염과의 관련성을 분석하였다. 치주염 유병률은 성별, 나이, 결혼상태, 교육, 수입에 따라 통계적으로 유의한 차이가 있었으며(p<0.05), 주관적 건강상태, 심혈관질환 여부, 당뇨 여부, 음주행태, 흡연상태, 및 BMI에 따른 차이도 통계적으로 유의하였고(p<0.05), 칫솔질 횟수, 주관적 구강건강상태, 구강위생용품 사용여부에 따른 차이도 통계적으로 유의하였다(p<0.05). 한편 고려된 비타민 중 비타민 A와 레티놀 및 비타민 B2 섭취가 적을수록 치주염 유병위험이 통계적으로 유의하게 높았고, 인구사회학적 특성과 전신건강상태와 행태 및 구강건강상태와 행태를 보정한 후에는 비타민 B2에서만 통계적으로 유의한 관련성이 있었다(OR: Q1=1.00, Q2=0.72, Q3=0.73, Q4=0.76, Q5=0.84). 따라서 적절한 비타민 B2의 섭취는 치주염 유병위험을 감소시킴으로써 한국 성인 인구의 지속적인 치주건강을 유지하는 데 도움이 될 수 있을 것으로 생각된다.

This case report describes the treatment of an adult female patient with a history of periodontal disease, Class I malocclusion with extrusion, dental spaces, and pathologic tooth migration. The patient was treated with clear aligners, which effectively controlled the strength and direction of orthodontic forces after 3 months of systematic periodontal treatment. The Peer Assessment Rating (PAR) index was calculated from study models before and after treatment. The pretreatment PAR score was 24, and the posttreatment PAR score was 4. The PAR score for this patient changed by 83%. Satisfactory appearance and good function were achieved for this patient.

The purpose of this study was to an in estimate the antibiotic susceptibility of P. gingivalis and P. interrnedia isolate from the subgingival plaque to adult periodontitis. Six P. gingivalis and five P. intermedia bacterial strains were tested for their susceptibility to 10 antimicrobial agents under disc diffusion method and broth dilution method. Ten patients with deep pocket(6mm) were selected for this study. They had not taken antibiotics for 6 months and no history of dental treatment for 6 months before this study. The result were as follow : 1. For antibiotic disc diffusion method, six P. gingivalis and five P. interrnedia were tested with 10 antimicrobial agents which comprised penicillin, gentamycin, clindamycin, lincomycin, ampicillin, erythromycin, tetracycline, amikacin, chloramphenicol, vancomycin. The sensitive antibiotics were tetracycline, penicillin, ampicillin, vancomycin, chloramphenicol and resisitent antibiotics were lincomycin. The other antimicrobial agents were less active. 2. From the study of determination on the minimal inhibitory concentration(MIC) by broth dilution method, the MIC of tetracycline to P. gingivalis and P. intermedia were $0.5-1.0{\mu}g/ml$, $0.5{\mu}g/ml$, that of ampicillin were $1-8{\mu}g/ml$, that of clindamycin were $1-32{\mu]g/ml$, $8-16{\mu}g/ml$, that of lincomycin were $16-32{\mu}g/ml$, $2-32{\mu}g/ml$. These data suggest that tetracycline and ampicillin may be valuable drug in the elemination of P. gingivalis and P. interrnedia from the patients with adult periodontitis.

The present study was performed to evaluate the relationship between the serotype or the genotype of Actnobacillus actinomycetemcomitans (A. a.) and the severity of periodontal disease. Total 64 A. a. clinical isolates were sampled from 46 sites of 20 subjects classified into the group I (1 periodontally healthy subject, 2 gingivitis patients, 5 ealry adult periodontitis patients), group II (3 moderatelly adult periodontitis patients) and group III (1 advanced adult periodontitis patient, 8 RPP patients). Southern bolt hybridization (fingerprinting) patterns of the five reference strains, A. a. strain ATCC 29523 (serotype a), ATCC 29522 (Serotype b), ATCC 43719 (serotype c), IDH 781 (serotype d) and IDH 1705 (serotype e), were used as the five basic genotypic patterns (A, B, C, D, E). NT type was designated as one which did dnot represent any of those five basic types. The serotypes were determined by ELISA technique with the serum samples from pre-immunized rabbit. Based on subject-based analysis, it was noted that genotypes A and C, NT, and B, D, E were significantly related to the disease groups I, II, and III, respectively. It was also noted that both the serotypes a and c were significantly related to the disease group I and II, while serotypes were significantly related bm), and serotypes b and nd were frequently found in sites with severe attachment loss (LA>6mm). The results indicated that the significant relationship can be delineated beteen the genotypes and the serotypes of Acinobacillus actinomycetemcomitans and the periodontal disease severity. The results also indicated that genotyping can provide more detailed information on its relationship with the disease severity based on both the patient-based and the site-based analyses.

The 16S rRNA analyzing method is a bacterial identification method that is useful in identifying bacteria which is difficult to do by other means. The following 7 types of bacteria which are Treponema, A. actinomycetemcomitans, P. gingivalis, Fusobacterium, B. forsythus, P. intermedia, P. micros were evaluated in order to study their distribution among patients with adult periodontitis. The 16S rRNA analyzing method was used to compare bacterial distribution among 3 groups. Subgingival plaque acquired from the affected sites(pocket depth ${\geq}6mm$) of 29 patients with adult periodontitis were grouped as the experimental group while plaque from the non-affected sites(pocket depth ${\leq}3mm$) were grouped as control 2 and finally plaque acquired from students with healthy periodontal tissues were grouped as control 1. The results are as follows ; 1. The distribution of Treponema was 12.5% for control 1, 21.4% for control 2 and 75.4% for the experimental group. For A. actinomycetemcomitans the distribution was 0.5%, 19.0%, 44.4% in respect to the order of groups mentioned above. P.gingivalis showed 10.5%, 43.1%, 94.0% distribution, Fusobacterium 33.0%, 48.3%, 81.0% distribution, B. forsythus 9.5%, 17.2%, 65.9% distribution, P. intermedia 1.0%, 12.1%, 26.3% distribution and finally P. micros 5.0%, 19.0%, 48.7% respectively. In all 7 types of bacteria, the experimental group showed higher bacterial distribution compared to the other two groups with statistically significant difference. 2. In the case of Treponema, A. actinomycetemcomitans, gingivalis,Fusobacterium, B. forsythus, P. intermedia, P. micros showed significant difference between control 1 and 2. These results suggest that the 16S rRNA analyzing method which was applied on Koreans for the first time could be utilized and useful in finding potential pathogens of periodontal disease.

Purpose: The pathology of peri-implantitis is still not fully understood and there have been recent challenges to the consensus on its aetiology and pathology, especially in comparison with periodontitis. The assessment of biomarkers allows a comparison of the pathology of these diseases. The aim of this systematic review was to answer the research question: "Is there a difference in the biomarkers associated with peri-implantitis compared with periodontitis in adult humans?" Methods: Electronic databases were searched and screened, and a manual search was also undertaken. The inclusion criteria were adults with peri-implantitis who had been compared to adults with periodontitis with the outcome of biomarkers assessed via biopsies or crevicular fluid samples in primary or secondary care settings, as recorded in case-control, case series and retrospective, prospective and cross-sectional observational studies. Two reviewers independently screened titles and abstracts and assessed full text articles for eligibility and inclusion. Both reviewers independently extracted data and assessed risk of bias. Differences in biomarker levels were the primary outcome and a narrative review was undertaken due to the heterogeneity of studies. Results: In total, 2,374 articles were identified in the search, of which 111 full-text articles were assessed for eligibility and 13 were included in the qualitative synthesis. Five of the 13 included studies were deemed to be at high risk of bias, with the others having moderate risk. All studies were cross-sectional and performed at university hospitals. Nine of the 13 included studies found significant differences in the levels of biomarkers or their ratios between periimplantitis and periodontitis. Four of the studies found no significant differences. Conclusions: Within the limitations of the included studies, it appears that there may be a difference in biomarker levels and ratios between peri-implantitis and periodontitis, suggesting that these disease processes are somewhat distinct.
