A study aimed at the determination of the microbial flora in the gingival fluid and carries and paradontal bursal fluid. 30 persons in Dinh Dong commune, Thanh Tri district Hanoi classified as age, gender participated the study. The results have shown that there was a balance of the microbial flora in the mouth and gingival fluid and carries and paradontal bursal fluid. The imbalance occurred when gingivitis or periodontitis appeared. The highest increased microbials were anaerobic microbial and spirillum.

The aim of this investigation was to study the effect of orthodontic force on the flow of gingival crevicular fluid and activities of arylsulfatase and brta-glucuronidase in crevicular fluid. The material consisted of 12 persons between the ages of 13 years and 22 years and all were categorized Class I, 4-4 extraction cases Crevicular fluids were sampled from distal crevis of each canine before treatment (phase 1), after bracketing (phase 2), after application of force (phase 3) and after run out of orthodontic force (phase 4). Crevicular fluid flow did not show any significant changes during the period of treatment. The activities of arylsulfatase increased significantly after setting of orthodontic appliance without application of force, but did not show any significant difference after application of force. The activities of beta-glucuronidase increased significantly after application of orthodontic force and decreased with force deminished. These indicated that beta-glucuronidase was good indicator of bone remodelling resulted from initial orthodontic force.

OBJECTIVEGingival crevicular fluid (GCF) analysis of various inflammatory mediators has been investigated as a means of providing objective criteria of peri-implant tissue health. In this report, the crevicular fluid levels of interleukin-8 (IL-8), GCF volume and clinical parameters were studied.

METHODSGCF was sampled from 35 healthy and 35 inflamed sites of implantation patients. IL-8 levels were analysed using ABC-ELISA. Clinical parameters were measured, and data analysis was performed using the software package SPSS10.0.

RESULTSSignificant difference was observed between healthy implant sites and peri-implantitis sites. GCF volume was positively correlated with PD, PI, GI and MOB. The total amount of IL-8 was positively correlated with PD and GI.

CONCLUSIONThis investigation suggested that GCF volume and IL-8 cytokine may be of value as a diagnostic and prognostic marker for peri-implantitis.

ABSTRACT Root resorption is a shortening of root dentine which occurs physiologically in deciduous teeth. The present study aimed to quantify dentine sialophosphoprotein (DSPP), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in gingival crevicular fluid (GCF) during the physiological process of root resorption of deciduous teeth. A cross-sectional study was conducted with 25 children aged between 4 and 10 years old. GCF was collected from the gingival sulcus using periopaper strips from the upper first deciduous molar (n = 45). The samples were divided equally into three groups, no resorption (R0), moderate resorption (RM) and severe resorption (RS), based on the existing radiographs taken. The GCF samples were then analysed using an enzyme-linked immunosorbent assay (ELISA) kit to determine the DSPP concentration levels and BioAssays System kit for AST and LDH. One-way ANOVA was used to determine the statistical differences between the means of the DSPP, AST and LDH concentration level in the three groups. A difference was considered significant when p < 0.05. High concentration levels of DSPP were significantly noted in RS (p < 0.05), compared to RM and R0. AST also portrayed significant high activity level (p < 0.05) similar to DSPP but LDH showed no significant changes between groups (p > 0.05). The high quantification of DSPP and AST levels in the severe and moderately resorbed roots indicated the potential use of this protein as a biomarker for detecting moderate-severe stages of root resorption.

PURPOSE: In this study, we compared low-power CO2 laser treatment to ultrasonic scaling, which is generally approved as a power-driven mechanical instrumentation, and evaluated both of these treatments regarding their clinical effectiveness and change in the volume of in GCF. MATERIAL AND METHODS: 20 patients who had gingivitis were selected. all of patients has no systemic problems. Randomly selected, one quadrant received ultrasonic scaling only, another quadrant received ultrasonic scaling and CO2 laser irradiation, the other quadrant received CO2 laser irradiation only. Clinical parameters measured at baseline, 1 weeks, 2weeks, 4weeks and 8weeks RESULT: Pocket probing depth and clinical attachment level were not changed during study period. Gingival index of all group were improved after treatment. At 1 weeks after treatment, Gingival index of ultrasonic scaling group was only significantly different compared to control group. At 2 weeks after treatment, gingival index of all experimental group were significantly different compared to control group. At 4 and 8 weeks after treatment, gingival index of all group were increased, but experimental group were lower than control group. Sulcus bleeding index was similar to the results of gingival index. At 1 weeks after treatment, all experimental group were significantly different compared to control group and it maintained during study. At 2 weeks after treatment, sulcus bleeding index of all group were lowest during study. Gingival crevicular fluid were measured with Periotron(R) 8000(Oraflow(R) , Inc. USA). At baseline, all group were showed moderately severe condition. At 1 week after treatment, laser treatment only group was reduced quantity of gingival crevicular fluid mostly, and all group were reduced quantity of gingival crevicular fluid. At 2 weeks after treatment, all group were healty state. At 4 and 8 weeks after treament, all group were showed recurrent of inflammation, and control group was the most significantly increased. CONCLUSION: This study showed that the effects of CO2 laser treatment were similar to conventional ultrasonic scaling and this result remained longer than plaque control only. These results suggest possibility of CO2 laser treatment for altered periodontal therapy.

PURPOSE: The present split mouth study evaluates the effect of nonsurgical periodontal treatment on the gingival crevicular fluid (GCF) leptin level in chronic periodontitis. METHODS: Ninety sites from 30 nonobese chronic periodontitis patients were selected and divided as follows: group I, 30 healthy sites receiving no treatment; group II, 30 periodontitis sites receiving scaling and root planing (SRP); and group III, 30 periodontitis sites receiving SRP with tetracycline local drug delivery. At baseline, after GCF sampling and clinical parameter recording, the assigned treatment was performed for the study groups. During recall visits, GCF sampling followed by clinical parameter recording was done for groups II and III. RESULTS: Reductions in the probing depth and the clinical attachment level (CAL) were highly significant at different time intervals (except between day 0 and 45) in both groups II and III. Upon comparison, group III showed significant gain in CAL between day 0 and 15 and between day 0 and 45. After treatment, the reduction in the GCF leptin level was more significant in group III than in group II at day 15 but re-elevated almost to the pretreatment levels at day 45. CONCLUSIONS: Nonsurgical periodontal therapies were not effective in maintaining stable reduction in the GCF leptin level during the study period.

OBJECTIVES: The aim of this study was to examine the effect of a Polycan-calcium gluconate complex on gingival health. METHODS: Forty-one subjects with mild periodontitis (> or =40 years) were divided into two groups: the placebo and test product (Polycan-calcium gluconate complex twice a day for 4 weeks) groups. Oral examination was performed and gingival crevicular fluid (GCF) was collected from each subject at baseline and after 4 weeks. Interleukin (IL)-1beta level in the GCF was determined using enzyme-linked immunosorbent assay. RESULTS: Pocket depth and plaque index were significantly decreased in the test group at 4 weeks. The level of IL-1beta and plaque index of the treatment group was significantly lower than of the placebo group. CONCLUSIONS: Based on the above results, Polycan-calcium gluconate complex may inhibit plaque accumulation in the mouth and may have a negative correlation with the level of inflammatory biomarkers. Consequently, gingival health was significantly improved by polycan-calcium gluconate complex.
