Purpose: The attachment level is strongly associated with tooth loss and provides useful information on patterns of destruction of the periodontium. The presence of horizontal attachment loss would not be detected in clinical measurement. Therefore, the purpose of the present study was to estimate the patterns of periodontal destruction based on the attachment area and horizontal attachment loss in extracted teeth due to severe periodontitis. Materials and Methods: 307 teeth satisfied the criteria for assessment. An indirect method, based on digital images obtained from a digital camera and an image analysis program, was used to calculate the area of root surface and attachment loss and the extent of horizontal attachment loss. The data were analysed using SPSS. Results: No statistically significant differences among root surfaces were observed in anterior teeth on the loss of attachment area. However, in posterior teeth statistically significant differences in palatal surfaces of maxillary and mandibular premolar and molar surfaces compared with buccal surfaces were observed. Horizontal attachment loss was observed in 21.5% of the teeth examined. Frequency of horizontal attachment loss was highest in the maxillary first premolar (34.8%), followed by the maxillary second premolar (27.3%) and maxillary canine (25%). The mean length of horizontal attachment loss was 1.5mm. Conclusion: More meticulous examination will be needed of the palatal surfaces of maxillary and mandibular premolar and molar teeth. The percentage of teeth with horizontal attachment loss greater than 2.1 mm was 5.2%. Considering the length of curette blades, about 5.2% of teeth were not properly debrided. Therefore, Additional supportive therapy such as local drug delivery has to be considered in treatment of the first maxillary, second premolar and canine due to the high prevalence of horizontal attachment loss.

Purpose : Preservation of the periodontal health of the treated patient requires supportive periodontal therapy for the elimination of periodontal disease. After Phase I therapy is completed, patients are placed on a schedule of periodic recall visits for maintenance care to prevent recurrence of the disease. The amount of tooth loss would be the most relevant criterion in an evaluation of the effect of periodontal treatment, but this would require studies with extremely long follow-up periods. Thus the most commonly used outcome criteria in clinical research have been clinical attachment level change, reduction of pocket depth and bleeding frequency. The purpose of this case study is to identify the effect of supportive periodontal therapy after periodontal flap surgery. Materials & Methods : Following routine hygienic phase of treatment, patients with chronic periodontitis received surgical periodontal treatment. Bleeding on probing, pocket depth and clinical attachment level were measured at baseline, pre-operation and 1 year follow up. All procedures were performed by one operator. Results : One year a total of 28 patients (58sites) to recheck remained, when conducted maintenance program after periodontal flap surgery was observed reduction of bleeding frequency, pocket depth and improvement of clinical attachment level. Conclusion : The results from this study indicate that supportive periodontal therapy after periodontal flap surgery is effective for reduction of bleeding frequency, pocket depth and gain of clinical attachment level.

The ultimate goal of periodontal treatment is to regenerate the lost periodontal apparatus. Many studies were performed in developing an ideal bone substitute. Anorganic bovine-derived xenograft is one of the bone substitute, which were studied and have been shown successful for decades. The aim of this study is to evaluate the effect anorganic bovine-derived xenograft. Total of 20 patients, with 10 patients receiving only modified widman flap, and the other 10 receiving anorganic bovine-derived xenograft and flap surgery, were included in the study. Clinical parameters were recorded before surgery and after 6 months. The results are as follows: 1. The test group treated with anorganic bovine-derived xenograft showed reduction in periodontal pocket depth and clinical attachment level with statistically significance(p<0.001) after 6 months. The control group treated with only modified Widman flap showed reduction only in periodontal pocket depth with statistically significance(p<0.001) after 6 months. 2. Although periodontal probing depth change during 6 months did not show any significant differences between the test group and the control group, clinical attachment level gain and re-cession change showed significant differences between the two groups(p<0.05). On the basis of these results, anorganic bovine-derived xenograft improves probing depth and clinical attachment level in periodontal intrabony defects. Anorganic bovine-derived xenograft could be a predictable bone substitute in clinical use.

The purpose of this investigation was to examine the pattern of progression of periodontitis and the change in the extent and severity of the periodontal condition in young adults. Fourteen subjects with periodontitis, 11 males and 3 females in the age range 22-26, participated in the study. Following a baseline examination, the subjects were monitored for gingival index, probing pocket depth, gingival recession, probing attachment level and radiogrphic crestal bone height for 24 months without therapy. Re-examination were performed after 12 and 24 months. Gingival index, probing pocket depth, gingival recession and probing attachment level were assesed at 6 locations per tooth, and crestal bone height was assessed by subtraction radiography. The results from the follow-up examination revealed that the subjects underwent minor changes with respect to a series of different clinical parameters. The mean values of gingival index was improved, however, the mean values of probing pocket depth, gingival recession, probing attchment level and crestal bone height showed no significant change between baseline and the re-examination after 1 and 2 years.

Periodontal disease is one of the most common chronic diseases. Even though scaling and root planing are helpful for preventing periodontal disease, most people overlook it. So, the purpose of this study was to investigate oral care habits and the prevalence of periodontal disease to improve disease prevention and oral healthcare. This study was based on subpopulation of Donggu, Gwangju, Korea, for people older than 50, where oral examination and panoramic radiography were performed. Oral examination included O`Leary index, BOP (Bleeding on Probing), PD (Probing Depth), and CAL (Clinical Attatchment level). The subjects were 4025 people who responded to a oral health questionnaire. The prevalence of periodontal disease in the subjects were 10.3%, 56.1%, and 33.6% for slight, moderate, and severe periodontitis, respectively. The prevalence of periodontal disease was higher in men and older aged people in general. With respect to oral care habits, when subjects visited a dental center regularly and used oral hygiene devices, the ratio of the O`Leary Index was over 75%, the BOP was less than 25%, and severe PD and CAL (≥7 mm), and the prevalence of periodontal disease was less. Since the prevalence of periodontal disease was higher in male and increased with age, self-motivation about oral care habits, regular dental visits and oral care, such as scaling, root planning, and tooth brushing, are required for these groups. In addition, use of oral hygiene devices, such as dental floss and interdental brushes, is also.

Objectives: The main cause of periodontal disease is due to anaerobic bacteria existing around periodontal tissue. Methods: A group of 36 people who visited the periodontal prevention center of G Dental Hospital in Changwon-si, Gyeongsangnam-do, and who performed 4 times of professional periodontal prophylaxis, was finally selected and entered into a self-filling ceremony from April 25, 2019 to September 20, 2019. Data were analyzed using the statistical package SPSS (ver 25) a chi-square test and frequency analysis were performed. Results: P. gingivalis showed a significant difference in CAL, probing depth and tongue index were not significant among the clinical periodontal indices. T.Forsythus and T.denticola showed significant differences in Probing Depth, CAL, and tongue index. P. gingivalis, T. forsythus, T. denticola all decreased before and after expert periodontal prophylaxis, but T. denticola showed a significant difference. (p<0.05) Conclusions: The results of this study implied that the professional periodontal preventative care greatly reduced the number of periodontal bacteria, not exterminate the periodontal bacteria.

Periodontitis is the most prevalent noncontagious disease. Periodontal probing for measuring probing depth (PD) and clinical attachment level (CAL) has been an important diagnostic tool to determine the presence and severity of periodontal diseases. For probing reproducibility, adroit probe handling with constant force is required.

Periodontal regeneration is the type of wound healing occurring after periodontal therapy, which constructs new connective tissue attachment and new alveolar bone. Enamel matrix derivative (EMD) is obtained from developing porcine embryonal enamel and is composed of hydrophobic enamel matrix protein. Enamel matrix has an ability to induce acellular cemental regeneration in periodontal defects. Among various indications for EMD application reported in literature, EMD has been used as one of regenerative treatment options for intrabony defects which showed reduction of probing pocket depth (PPD) and gain of clinical attachment level (CAL). Moreover, EMD was reported to have no complications in clinical trials. This case report is to explore the short-term outcomes of EMD applied in three-wall vertical bone defects and to discuss the efficacy of EMD in the treatment of intrabony defects.

tachment level was changed from $8.67{\pm}1.72mm$ to $7.00{\pm}1.60mm$ (control); from $8.93{\pm}2.23mm$ to $6.00{\pm}1.92mm$ (test); and bone probing depth was decreased from $10.20{\pm}1.90mm$ to $9.07{\pm}1.95mm$ (control); from $10.14{\pm}2.14mm$ to $7.43{\pm}2.06mm$ (test). This study indicates that treatment of periodontal intrabony defects with EMD is clinically superior to treatment without EMD (OFD alone) in every parameter evaluated. Within the limits of this study, the application of EMD in intrabony defects resulted in clinically significant gain of clinical attachment level and decrease of bone probing depth. And further controlled clinical studies are required to confirm the effectiveness of the EMD in the treatment of various osseous defects.
