The aim of this systematic review was to evaluate clinical and microbiological outcomes with the use of azithromycin as an adjunct to non-surgical subgingival professional mechanical plaque removal (PMPR) in the treatment of grade C periodontitis. Online database searches using high-level MeSH terms in a PICO structure were conducted along with hand-searching of relevant periodontal journals. Titles and abstracts of identified studies were independently reviewed by both authors and the full texts of studies meeting the inclusion criteria were independently reviewed. In total, 122 studies were identified through searches, of which 6 were included in the qualitative analysis and 4 in the meta-analysis. Three studies included in the meta-analysis were deemed at low risk of bias and 1 at serious risk. There were conflicting results on whether azithromycin reduced the number of subgingival pathogens or detectable subgingival Aggregatibacter actinomycetemcomitans between the included studies. The meta-analysis revealed a statistically significant probing depth reduction difference in favour of azithromycin compared to the control at 3 months (weighted mean difference [WMD]=-0.39 mm; 95% confidence interval [CI], -0.66 to -0.13 mm; I2=0%) and 12 months (WMD=-1.32 mm; 95% CI, -1.71 to -0.93 mm; I2=0%). The clinical attachment level change was also statistically significant in favour of azithromycin compared to the control at 3 months (WMD=-0.61 mm; 95% CI, -1.13 to -0.10 mm; I2=71%) and 12 months (WMD=-0.88 mm; 95% CI, -1.32 to -0.44 mm; I2=0%). Based upon these results, azithromycin offers additional improvements in some clinical parameters when used in conjunction with subgingival PMPR in patients with aggressive periodontitis over control groups. These improvements appear to be maintained for up to 12 months after treatment completion. However, due to a lack of well-designed studies, the conclusions that can be drawn from the available evidence are limited.
To educate the technique performing oral health care by oneself, four times individualized oral instruction was introduced to patients and control marks of plaque on sex, age, occupation, monthly average income, academic career were measured respectively. Through analysis of it's results and evaluation of oral health care grade on patients, this study arranged for basic data about individualized oral instruction to improve public oral health. 1. As individualized oral instruction was processed, control mark of dentalplaque improved greatly. 2. Control mark of dentalplaque on sex, female's control mark was higher than male's it. But, a gap of control mark was small. 3. Control mark of dentalplaque on age, control mark of patients in their 50s to 59s and 30s to 39s was higher than average of the whole. 4. Control mark of dentalplaque on occupation, control mark of inoccupation and professional was highly appeared. 5. Control mark of dentalplaque on monthly average income, control mark of patients whose monthly average income was below 2.5 million was highly appeared. 6. Control mark of dentalplaque on academic career, control mark of patients who graduated of university was highly appeared at first and second evaluation. On the other hand, control mark of patients who graduated of college or dropped out of university was highly appeared at third and fourth evaluation. According to the above statements, to effectively take care of oral health, our felt keenly the necessity of the individualized repeated instruction.
The purpose of this study was to assess the clinical and microbiological effect of chlorhexidine rinse following scaling and root planing on periodontits. 10 patients with periodontal disease were selected for the study. They had not taken antibiotics for months and no history of dental treatment for 6 months before the study. They were good in general health. Patients received a scaling and root planing under local infiltration anesthesia, chlorhexidine rise group were subjected to twice a day 0.1% chlorhexidine rinse for a period 2 week. After initial clinical(plaque index, gingival index, probing pocket depth), microbiological and BANA tests were determined, each subject received a single session of scaling and root planing but no oral hygiene instructions. Clinical indices were measured, microbial parameters and BANA test were reassessed 1, 2 and 4 weeks after treatment. The results were as follows : 1. Plaque index, gingival index and pocket depth in chlorhexidine rinse group and control group were not significantly reduce during all weeks when compared chlorhexidine rinse group with control groups. Plaque index in chlorhexidine rinse group and control group were siginificantly reduced at 1, 2, 4weeks(P<0.05), gingival index and pocket depth wee ignificantly reduced at 2, 4weeks in both groups(P<0.05). 2. Perecntage of cocci and motile rods was significantly changed at 1, 2, 4weeks in chlorhexidine rinse group(P<0.05), control group was significantly changed at 4weeks in control group(P<0.05), intergroup difference was significantly at 2weeks in cocci and 4weeks in motile rods(P<0.05). 3. Percentage of non-motile rods in all group were not significantly changed when compared with those of baseline. 4. Percentage of spirochetes was significantly reduced at 4 week(P<0.05), control group was not significantly reduced during all weeks. 5. BANA test scores was significantly reduced during all weeks in chlorhexidine rinse group(P<0.05), control group was not significantly reduced during all weeks. The result showed that clinical and microbiological effect following scaling, root palning and chlorhexidine on periodontal disease.
This study aims to investigate the effect of four-week oral health promotion program operated through the cooperation between professionals and teachers of community child centers by reflecting characteristics of the centers and to suggest oral health promotion program applicable to community child centers. 4 community child centers has an enrollment of 119. 53 (44.5%) children completing the first and the second questionnaire survey were analyzed in this study. When dental plaque scores of 41 participants joining all of the first- to the fourth- week program and undergoing the dental plaque examination were compared before and after the oral health promotion program for community child center, the plaque control score was improved after the repeated education(p<0.05). Oral health knowledge and awareness of children in community child center were positive improved by oral health promotion program(p<0.05). And number of tooth-brushing a day improved by oral health promotion program. These findings suggest that there was a need for various oral health promotion program development in the community.
The authors observed the long term effects of chlorhexidine varnish treatment on microbial change of dental plaque in orthodontic patients with fixed appliances. The initial sample was 100 patients who were arranged to be treated with fixed orthodontic appliances. The final sample consisted of 21 patients who could be traced for 32 weeks after application of fixed orthodontic appliances. They were classified into the experimental group (12 patients) and the control group (9 patients). The experimental group was treated with chlorhexidine varnish once a week for 4 weeks before application of fixed orthodontic appliance. The control group was not treated with chlorhexidine varnish before application of fixed orthodontic appliance. The experimental group was treated once more after 20 weeks. The microbial changes of dental plaque were analysed by indirect immunofluorescence technique at pre-treatment, post-treatment 4, 8, 20, and 32 weeks. The results were as follows. 1. In the experimental group, streptococus mutans was significantly suppressed during experimental period. (p<0.01) But, in the control group, streptococcus mutans was significantly increased after placement of fixed orthodontic appliances during experiment period. (p<0.05) 2. Streptococcus sanguis, Streptococcus mitis, Actinomyces viscosus, md Actinomyces naeslundii did not show significant change between the experimental and the control group during experiment period. So, if we treat the orthodontic patients with chlorhexidine varnish before application of fixed appliances, we may suppress the major cariogenic bacteria, Streptococcus mutans, selectively for long period.
This study was performed to estimate the effect of plaque control on the progress of the repair pattern of the alveolar bone surface after bone surgery. In this experiment six mongrel dogs were used, four of them were as experimental group and others were as control. In the case of experimental group, dental floss ligature was tied over the neck of crown for permiting of plaque accumulation during one week before surgery and oral hygiene procedures were not performed. In control group, all the surgical intervention was done as same procedure with experimental except oral hygiene program. After surgery plaque was controlled during one week with using the chlorhexidine brushing. Animals were sacrificed at 1,2,4,6 weeks after osseous surgery. The results were as follows : 1. The alveolar bone defects were covered with regenerated epithelium at one week, matrix change of granulation tissue on subcutaneous area was observed, and new bone formation was initiated from the surface of the bone defects. 2. The connective tissue arrangement revealed more dense, new bone formation by osteoblasts was active at 2 weeks and proliferation of gingival epithelium and alveolar bone tissue were evident at 4 weeks, and almostly recovered to normal condition at 6 weeks. 3. In experimental group, inflammatory reaction was persistent in early stage and bone repair was delayed compared to control group. 4. In control group, matrix change of granulation tissue was initiated from one week, regeneration of gingival epithelium and maturation of subcutaneous conective tissue and new bone formation were evident at 2 weeks, so almost normal bone regeneration was observed at 4,6 weeks.

Previous studies have shown that Magnoliae cortex and Ginkgo biloba extracts were showed on the antimicrobial and anti-inflammatory action, in vitro. The purpose of this study was to evaluate on the effect of antimicrobial and anti-inflammatory activity of Magnoliae cortex and Ginkgo biloba extracts containing dentifrice in gingivitis. 70 subjects with gingivitis were divided into an experimental group which performed normal oral hygiene procedure with Magnoliae cortex and Ginkgo biloba extracts containing dentifrice and a control group which also performed normal oral hygiene procedure with the same dentifrice without the natural extracts and completed a doubleblind, cross-over study. At baseline and 3 weeks, subjects were assayed for clinical study by plaque index, gingival index, pocket depth, GCF rate, and microbiological study by subgingival dental plaque bacterial morphotypes by phase contrast microscopy, total anaerobes, total aerobes, Black pigmented bacteroides, A.actionomycetemcomitans, A.viscosus, C.rectus, Ssenguis; P.gingivalis, P.intennedia by bacterial culture and immunofluorescence microscopy. After 3 weeks using their respective dentifrices, reductions in the clinical indices of subjects were similar between the experimental dentifrice group and a control dentifrice group except for statistically significant much reductions in PI, GI, and GCF rate in the experimental dentifrice group as compared to control dentifrice group. Also statistically significant reductions in the motile rods and Spirochetes were found in both experimental group to compare with control group, however statistically much reduction in total anaerobes, Black pigmented bacteroides, and P.gingivalis, P.intennedia were found in the experimental dentifrice group as compared to control dentifrice group. This results indicates that Magnoliae cortex and Ginkgo biloba extracts containing dentifrice might be useful for elimination of gingival inflammation.
Purpose: The goal of this study was to evaluate the clinical anitplaque and antigingivitis effects of a mouthrinse containing cetylpyridinium chloride (CPC), triclosan and dipotassium glycyrrhizinate (DPZ) in patients with gingivitis and mild periodontitis. Methods: Thirty-two subjects were randomized into 2 groups. The test group used a mouthrinse containing 0.05% CPC, 0.02% triclosan and 0.02% DPZ, while the control group used a placebo mouthrinse. At baseline, 2 weeks and 4 weeks, the papillary bleeding index (PBI), Turesky-Quigley-Hein plaque index (PI) and L$\ddot{o}$e-Silness gingival index (GI) were assessed. During the experimental period, the patients used the mouthrinse for 30 seconds, 4 to 5 times/day (10 mL/time) within 30 minutes after toothbrushing. Results: No adverse effects appeared in either the experimental or the control group. Regarding PBI, PI and GI values, statistical significance was detected between values at baseline and 2 weeks for both groups (P<0.05). In the experimental group, statistically significantly lower values were detected at 4 weeks compared to at 2 weeks. However, in the control group, no statistically significant difference was detected between the values at 2 weeks and 4 weeks. Additionally, the mean value after 4 weeks for the control group was slightly higher than the mean value after 2 weeks for the control group. Conclusions: This study for 4 weeks demonstrated that mouthrinses containing CPC, triclosan and DPZ may contribute to the reduction of supragingival plaque and gingivitis.
The purpose of this study was to evaluate the effectiveness of chlorhexidine varnish treatment in the prevention of dental caries in orthodontic patients by observing microbial change in dental plaque after varnish treatment. The sample consisted of 26 patients who were classified into an experimental group and a control group, 13 patients each. The experimental group was treated with chlorhexidine varnish once a week for 4 weeks. The control group was treated with placebo varnish using the same procedure, The microbial change was analysed by indirect immunofluorescene technique before treatment and 4 weeks, 8 weeks after treatment. The results were as follows. 1. Streptococcus mutans were strongly suppressed until 8 weeks after chlorhexidine varnish treatment(p<0.01). 2 The proportion of Streptococcus sanguis increased temporarily 4 weeks after chlorhexidine varnish treatment(p<0.05), decreased to original level after 8 weeks. 3. Streptococcus mitts, Actinomyces viscosus, Actinomyces naeslundii did not show significant change after chlorhexidine varnish treatment.
This study was conducted to investigate the effects of professional oral healthcare program in eldery residents long-term care facilities. Ninety-four elderly residents from 5 different facilities in Asan participated in this study. The subjects were divided into 3 groups, with 32 in experimental group I, 30 in experimental group II, and 32 in the control group. Subjects in experimental group I were treated by a dental hygienist with professional oral healthcare and received daily oral care from caregivers who had completed elderly oral healthcare course. Subjects in experimental group II received daily oral care from caregivers who had completed elderly oral healthcare course. Control group received daily oral care from caregivers. These 3 groups were tested for dental plaque, halitosis, tongue coating, and salivary flow at baseline, and after 4 and 12 weeks of treatment. There were significant differences in the dental plaque index between the groups, mediate times, and mediate methods, in halitosis between the mediate methods, and in tongue coating between the mediate times, as well as the mediate methods. Finally, salivary flow was significantly different with regard to mediate methods between experimental group II and the control group. Therefore, to improve the oral health condition of elderly residents, involvement of a part-time dentist and scheduled professional oral healthcare are necessary. Furthermore, elderly oral healthcare education for nursing staff, including managers, should be provided.
