Gingivectomy has been utilized as a therapeutic method to remove diseased periodontal pocket wall in order to aid in root planing. Although chemical agents and electrosurgery has been used in addition to the conventional method of using surgical blades, difficulties in controling the depth of chemical penetration and effectively regenerating the gingival tissue as well as the slow wound healing has been pointed out as shortcomings of these methods. This study was designed to assess the effect of Aloe vera on wound healing of gingivectomy sites created by $CO_2$ laser on palatal gingiva of maxillary molar region of white rats. Those sites treated by surgical blades were designated as control, by $CO_2$ laser as Experimental group I, by surgical blades in addition to topical application of Aloe vera as Experimental group II, and by $CO_2$ laser and Aloe vera application as Experimental group III. Animals were sacrificed at 2 days, 3 days, 1 week, 2 weeks and 3 weeks postoperatively, and the specimens were histologically analyzed. The results were as follows : 1. Resorption of blood clots were observed in the control at 3rd day, followed by the rest of the experimental groups at 1 week postoperatively. 2. Persistent inflammation was observed up to 1 week in the control and Experimental group II and III, and until the 2nd week in Experimental group I. 3. Granulation tissue was observed up to 1 week in the control, and 2 weeks in the rest of the groups. 4. Epithelization started on the 2nd day. The control showed the most rapid epithelization, and the process was completed by the 2nd week in all groups. 5. Experimental group II and III, which were treated with Aloe vera, showed similar healing patterns to the control and Experimental group I.

Objectives: Photodynamic therapy has been proven to promote additional clinical and microbiological benefits in the treatment of chronic periodontitis and aggressive periodontitis. The purpose of this study is to assess the effectiveness of the photodynamic therapy for patient with periodontitis. Methods: We searched the eight Korean databases and Ovid-MEDLINE, Ovid-EMBASE, Cochrane Library. Total 300 studies were searched and 13 studies were included in the final assessment. Each of the stages from literature search and extraction of data were carried out independently by 2 researchers. We used tools of Scottish Intercollegiate Guidelines Networks for assessment of the quality of studies. Results: The safety of the photodynamic therapy was assessed by bleeding. The effectiveness of the photodynamic therapy was assessed by the reduction of Probing pocket depth (PPD) and the gain of Clinical attachment level (CAL). The mean difference of PPD was 0.46(95% CI 0.09~0.82), (p=.01).). The mean difference of CAL was ?0.49(95% CI ?1.12~0.14), (p=.13). Conclusion: The additional use of $^{\circ}{\infty}$Antimicrobial Photodynamic Therapy for Periodontitis$^{\circ}{\pm}$ caused hemorrhage to similar extents to conventional treatment modalities, where scaling and root planing are solely performed, in patients with periodontitis who are expected to have a lower degree of treatment response to non-surgical or surgical periodontal therapies (implant or refractory periodontitis) and those where there is a concern for the possible occurrence of antimicrobial side effects or resistance. This indicates that there are no problems with its safety. But there were no consistent reports about the effects of the additional use of photodynamic therapy. This led to a decision that the safety and efficacy of the current technology deserve further studies (Recommendation rating of A, Classification of technology II-a).

Purpose: The purpose of this randomized single-blind controlled trial was to elucidate the clinical and antimicrobial effects of daily phototherapy (PT) as an adjunct to scaling and root planing (SRP) in patients with chronic periodontitis. Methods: The study was conducted from December 2013 to May 2014 at Ewha Womans University Mokdong Hospital, Seoul, Korea. Forty-one patients with mild to moderate chronic periodontitis were randomly divided into two therapeutic groups in a 1:1 ratio: SRP+PT and SRP (control) groups. All participants underwent full-mouth SRP. PT was performed thrice a day for a month by using electric toothbrushes with embedded light-emitting diodes. Plaque index, gingival index, probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing were assessed before (baseline) and four weeks after (follow-up) the treatment. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia, Fusobacterium nucleatum, Parvimonas micra, Campylobacter rectus, Eikenella corrodens, Streptococcus mutans, and Streptococcus sobrinus levels were detected by a real-time polymerase chain reaction at the same points in time. Results: The clinical parameters improved in both the groups. At the follow-up assessment, PPD was significantly decreased in the SRP+PT group (P=0.00). Further, PPD and CAL showed significantly greater changes in the SRP+PT group than in the SRP group (PPD, P=0.03; CAL, P=0.04). P. gingivalis and T. forsythia levels decreased in this group, but no significant intergroup differences were noted. Conclusions: Adjunctive PT seems to have clinical benefits, but evidence of its antimicrobial effects is not sufficient. Long-term studies are necessary to develop the most effective PT protocol and compare the effectiveness of PT with and without exogenous photosensitizers.

Purpose: Peripheral artery disease (PAD) is a form of arteriosclerosis that occurs in the extremities and involves ischemia. Previous studies have reported that patients with periodontitis are at high risk for PAD. However, the relationship between these 2 diseases has not yet been fully elucidated. In this cross-sectional study, we investigated this relationship by comparing patients with PAD to those with arrhythmia (ARR) as a control group. Methods: A large-scale survey was conducted of patients with cardiovascular disease who visited Tokyo Medical and Dental University Hospital. We investigated their oral condition and dental clinical measurements, including probing pocket depth, bleeding on probing, clinical attachment level, and number of missing teeth; we also collected salivary and subgingival plaque samples and peripheral blood samples. All patients with PAD were extracted from the whole population (n=25), and a matching number of patients with ARR were extracted (n=25). Simultaneously, ARR patients were matched to PAD patients in terms of age, gender, prevalence of diabetes, hypertension, dyslipidemia, obesity, and the smoking rate (n=25 in both groups). Real-time polymerase chain reaction was performed to measure the bacterial counts, while the enzyme-linked immunosorbent assay method was used to measure anti-bacterial antibody titers and proinflammatory cytokine levels in serum. Results: PAD patients had more missing teeth ($18.4{\pm}2.0$) and higher serum levels of C-reactive protein ($1.57{\pm}0.85mg/dL$) and tumor necrosis factor-alpha ($70.3{\pm}5.7pg/mL$) than ARR patients ($12.0{\pm}1.7$, $0.38{\pm}0.21mg/dL$, and $39.3{\pm}4.5pg/mL$, respectively). Meanwhile, no statistically significant differences were found in other dental clinical measurements, bacterial antibody titers, or bacterial counts between the 2 groups. Conclusions: Our findings suggested that PAD patients had poorer oral and periodontal state with enhanced systemic inflammation.

성숙된 치근을 갖는 제3대구치를 이용한 자가치아이식술은 효과적이며, 장기간 높은 성공률 보여주는 것으로 알려져 있다. 자가이식술 이후 생착 여부에 대해 경과 관찰하는 기간동안 치아가 심한 동요도를 보이는 경우, 이를 실패로 간주하고 발치를 하는 것이 일반적이다. 하지만, 이번 증례에서는, 자가치아 이식술 후 치아가 고정이 되지 않아, 구강 외로 탈락되었으나, 시기 적절히 재식을 시도하여 다시 생착을 획득하였고, 1년 이후까지도 성공적인 임상 결과를 보였다. 재식하였지만, 치근 흡수나 골소실도 보이지 않았다. 자가치아이식 후 교합적 문제로 고정을 보이지 않으나, 염증소견이 없는 치아라면 치조와에 재식하는 것이 발치에 앞선 대안이 될 수 있다.

Recently many researches on plaque removal effect and therapeutic effect of toothpaste containing natural medicines are being studied in early periodontal diseases. The purpose of this study is to examine the clinical and microbiological effect of toothpaste containing natural medicines such as camomile, rhatany, myrrh，sage oil, glycyrrhetinic acid and vitamin E. Sixty three subjects with gingivitis were divided into an experimental group which performed normal oral hygiene procedure with toothpaste containing natural medicines and vitamine E and a control group which also performed normal oral hygiene procedure with Syrinmed? toothpaste without containing herbal extracts and vitamine E. At the baseline, 2 weeks, and 4 weeks, subjects were analyzed for clinical study and microbiological study. After 2 weeks and 4 weeks use of their respective toothpastes, statistically significant decreases of gingival index, plaque index, and bleeding index were shown in both the control and the experimental group. The degree of decrease was more significant in the experimental group than the control group. A statistically significant decrease of pocket depth, and gingival crevicular fluid were shown in both the control and lie experimental group. A statistically significant increase of cocci was shown in both the control and the experimental group, the degree of increase was more significant in the experimental group than control group. A statistically significant decrease ofnon-motile rods, and motile rods were shown in both the control and the experimental group, the degree of decrease was more significant in the experimental group than the control group. Spirochetes increased weakly in both the control and the experimental group but a statistic significance was not shown. A statistically significant decrease of anaerobic bacteria, aerobic bacteria, and black pigmented Bacteroides were shown in both the control and the experimental group. These results indicate that the use of toothpaste containing natural medicines is effective in the prevention and the treatment of periodontal diseases.
