In the treatment of chronic adult periodontitis, scaling and root planing have been generally performed prior to periodontal flap surgery. The purpose of this study was to evaluate the clinical significance of nonsurgical periodontal therapy prior to periodontal flap surgery in patients with chronic adult periodontitis. Fifty six molars showing bilateral bony defects and 4-6mm periodontal pocket in twelve patients with chronic adult periodontitis were selected. By randomized split-mouth design, in one side, flap operation was performed 4 weeks after scaling and root planing, in the other group, flap operation was only performed without scaling and root planing. Probing pocket depth, gingival recession, clinical attachment level, gingival index, plaque index, and tooth mobility were measured at baseline, before flap operation and post-operation

The purpose of this study was to an in estigate the antibiotic susceptibiliity of Actinoobacillus actinomycetemcomitans isolated from the subgingival plaque to adult periodontitis. Seven bacterial strains were tested for their susceptibility to 10 antimicrobial agents under disk diffusion method and broth dilution methold, Seven 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 and no history of dental treatment for 6 months before this study. The results were as follows : 1. For the antibiotic disk diffusion method, seven A. actinimycetemcomitans were tested with 10 antimicrobial agents which comprised penicillin, gentamycin, clindamycin, lincomycin, ampicillin, erythromycin, tetracycline, amikacin, chloramphenicol, and vancomycin. The sensitive antibiotics were tetracycline, vancomycin, and chloramphenicol and the resistant antibiotics were clindamycin, and 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 seven strains of the A. actinomycetemcomitans was $0.5-1.0{\mu}g/ml$, that of clindamycin was $32{\mu}g/ml$. These data suggest that tetracycline may be valuable drugs in the elimination of A. actinimycetemcomitans from the patients with adult periodontitis

Objectives: The purpose of the study is to investigate the relationship between body mass index(BMI) and periodontal disease in Korean adult from the data of the fifth Korea National Health and Nutrition Examination Survey(KNHANES). Methods: The subjects were 3,309 adults from 25 ro 45 years old in the fifth KNHANES. The subjects were divided into three BMI categories: normal weight 1,549(BMI ${\leq}22.9kg/m^2$), overweight 792(BMI $23.0-25.0kg/m^2$) and obesity 968(BMI ${\geq}25.0kg/m^2$). Periodontal disease was assessed by community periodontal index(CPI) and periodontitis was defined as ${\geq}$ code 3. Results: Increased BMI adults had no significantly higher prevalence of periodontitis than those having normal body weight after adjusting for variables; the odds ratio(OR) was 1.06 in overweight and 1.23 in obesity. BMI and periodontitis had no significant relation to increased age, but the age increase tended to have high odds ratio. Women had a higher OR than men. Conclusions: Through this study, it is necessary to analyze the relationship between the obesity index and periodontitis in the further study.

본 연구는 한국 성인 여성의 수면시간과 치주염과의 관련성을 확인하기 위해 국민건강영양조사 제 6기 2차년도(2014) 자료를 바탕으로, 만 19세 이상의 한국 성인 여성 총 3,292명을 대상으로 연구를 수행하였다. 대상자의 일반적 특성(연령, 교육수준, 소득수준, 당뇨, 고혈압, 비만)에 따라 치주염의 차이를 확인할 수 있었으며, 흡연과는 관련성이 없는 것으로 나타났다. 수면시간이 7시간 이상인 대상자에 비해 7시간 미만인 대상자의 치주염 위험도가 1.37배(crude OR, 1.37; 95% CI, 1.13~1.65) 높았다. 그러나 대상자의 일반적 특성(연령, 교육수준, 소득수준, 당뇨, 고혈압, 비만)을 보정한 후의 수면시간이 치주염에 미치는 영향력은 더 이상 유의하지 않았다. 따라서 후속연구에서는 두 요인의 직접적인 인과관계를 밝힐 수 있는 전향적 코호트 연구가 수행되어야 하며, 성인 여성의 적절한 수면습관을 도모하고 아울러 구강건강 증진을 위한 포괄적 건강증진 프로그램의 시행이 필요하다고 생각된다.

The purpose of this study was to observe histopathologically the influence of advanced periodontitis on pulp tissue, and to conclude the correlation between the results with clinical manifestations. The samples were teeth with over 7mm pocket depth and over 50% radiographic bone loss. These were diagnosed to have very poor prognosis and thus planned to be extracted. Those with any of following conditions were excluded from the samples, loss of vitality, periapical pathology, restoration or prosthesis, dental caries, and attrition or abrasion. It was because these conditions could affect pulp without any correlation with periodontal disease. For the experiment, 17 teeth from 11 patients were selected. Average age of patient was 47. Each tooth was examined for following categoris; pocket depth, gingival recession, electric pulp test, mobility, percussion test, sensitivity test. The extracted teeth were fixed buffered neutral formalin solution. It was decalcified using 4% nitric acid. Sliced histological samples observed using light microscope, for pulp status, and severeity of inflammation. 4 samples were excluded due to histologic sample discrepency. Thus 13 samples were subject to observation. 4 showed normal conditions. Focal reversable pulpitis was shown in 5 samples. Chronic pulpitis was observed 1 sample. Pulpal abscess was observed in 3 samples.

Objectives: This cross-sectional study evaluated the prevalence of apical periodontitis (AP) and the technical quality of root canal fillings in an adult Kuwaiti subpopulation using cone-beam computed tomography (CBCT) images. Materials and Methods: Two experienced examiners analyzed 250 CBCT images obtained from Kuwaiti patients aged 15-65 years who attended government dental specialist clinics between January 2019 and September 2020. The assessment followed the radiographic scoring criteria proposed by De Moor for periapical status and the technical quality of root canal filling. Chi-square and Fisher's exact tests were used for statistical analysis, with significance level set at p < 0.05. Results: Among the 2,762 examined teeth, 191 (6.91%) exhibited radiographic signs of AP, and 176 (6.37%) had undergone root canal filling. AP prevalence in root canal-treated teeth was 32.38%, with a significant difference between males and females. Most of the endodontically treated teeth exhibited adequate root canal filling (71.5%). Conclusions: The study demonstrated a comparable prevalence of AP and satisfactory execution of root canal treatment compared to similar studies in different countries.
