Materials and Methods: A total of 60 subjects (33 males and 27 females) from age group 19 - 35 years, suffering from mild to moderate gingivitis were randomly divided into two groups. Group A (n = 30) participants were advised experimental (neem) gel and Group B (n = 30) participants were advised 0.2% chlorhexidine gel. All the clinical parameters (the gingival index by Loe and Silness [1], Plaque index by Silness and Loe [2] and sulcus bleeding index by Muhlemann H. R. and Sen S. [3]) were recorded at baseline, on the 14th day and 21st day by the same clinician in both groups. Results: on intragroup comparison the gingival index, plaque index and sulcus bleeding index decrease significantly in both the groups in all assessed periods. On intergroup comparison the indices did not differ significantly at baseline but after 2nd and 3rd week, the indices in Group B decrease more than the group A, which was statistically significant. Conclusion: Based on the observations of our study, it can be concluded that chlorhexidine gluconate as well as neem gel can be effectively used as an adjunct to mechanical plaque control in prevention of plaque and gingivitis. chlorhexidine gluconate gel has been found to be more effective when antiplaque and anti-inflammatory properties were considered. The effect of neem observed maybe because of its anti-inflammatory action. The antiplaque action of chlorhexidine gluconate is due to its substantivity. Substantivity of neem is required to be further studied.展开更多

A multi-center, randomized, double-blind, double-simulation, positive-controlled and parallel trial was conducted. A total of 136 patients exhibiting clinical symptoms of gingivitis were enrolled. The subjects were randomly assigned to two groups： test group （n=67）, in which rabdosia rubescens drop pill （960 mg） and 4 tablets of simulation agent of rabdosia rubescen were orally given to the subjects three times a day for 5 days; and control group （n=69）, in which the subjects were administered the tablets of rabdosia rubescens （1000 mg） and 24 drop pills of simulation agent of rabdosia rubescens thrice daily for 5 days. The experimental protocols and diagnostic criteria were established by expert panel prior to the experiment. The clinical symptoms were graded according to the severity of the disease and quantified. The total scores and scores for each clinical symptom of gingivitis were assessed at baseline and on the 6th day post-treatment. The therapeutic efficacy was compared between the two groups and in each group itself before and after the treatment. The results showed that in the two groups, the subjects who were given rabdosia rubescens, drop pill or tablet, had a decrease in total scores and scores for each clinical symptom when compared with those before treatment （P〈0.01）. There was significant difference in the therapeutic efficacy between the test group and the control group with the efficacy rate being 92.54% and 79.71% respectively （P〈0.05）. It was concluded that rabdosia rubescens showed great promise in treating gingivitis. And rabdosia rubescens drop pill was more efficacious than rabdosia rubescens tablet.展开更多

This inflammatory process is caused by several bacterial species inside the dental plaque. In vivo and in vitro experiments were set up. The patients of the in vivo group were divided into a noni and a control group. Both groups contained patients that suffered from gingivitis/periodontitis who were introduced to practice standardized, good oral hygiene. The patients in the noni group additionally used noni juice for mouth wash two times a day. The Papillae-Bleeding-Index (PBI) was evaluated comparing the status of inflammation in both groups. Bacterial probes were isolated from the patient’s gingival pouches for species identification and to carry out in vitro experiments for possible antimicrobial effects of noni juice. The Papillae-Bleeding-Index (PBI) in the noni group has “highly significantly” improved from an average of 2.25 at the beginning of the observation period (t0) to 1.01 after four weeks of noni treatment (t1), compared to a change from 2.11 at t0 to 1.95 at t1 inthe control group. A comparison of the differences of the PBI-values (t0-t1) between the noni and the control group was highly significant using a t-test on a level of p = 0.01. Only small inhibition zones were observed in the agar diffusion test on agar plates coated with aerobic, anaerobic and Candida cultures isolated from the patients gingival pouches after treatment with original or neutralized noni juice in different concentrations. Weak bacteriostatic effects occurred in the agar dilution experiments with noni juice in higher concentrations (native and neutralized noni juice). The present investigation has shown that the combination of good oral hygiene and the administration of noni juice was a promising treatment for gingivitis and periodontitis. The additional treatment with noni juice significantly mitigated the gingival inflammation.展开更多

Methods: A double-blind, randomized clinical trial was conducted in patients having chronic generalized gingivitis. Patients were randomly assigned to receive Nigella sativa oil(n=18) or chlorhexidine(n=19). The following assessments were made on day 0 and day 15: plaque index, gingival index, gingival IL-6 and IL-18 levels were measured using ELISA, plaque colony-forming units, and alpha-hemolytic Streptococcus strains. Data were analyzed using parametric and non-parametric tests and Fisher’s exact test.Results: Both interventions reduced plaque index and gingival index scores(P<0.000 1). The Nigella sativa oil group was better at lowering IL-6(P=0.007 6) than the chlorhexidine group(P=0.145), although there was no change in IL-18 levels(P>0.05). The post-intervention plaque index and gingival index scores and inflammatory cytokine levels between the two groups were not significantly different. Both interventions caused a significant reduction in the plaque colony-forming units(P<0.000 1), reducing pathogenic bacteria: Streptococcus mitis, Streptococcus oralis, Streptococcus sanguinis, and Streptococcus parasanguinis in the chlorhexidine group(50%)(P=0.103 1), and the Nigella sativa oil group(20%)(P=0.739 5). Conclusions: Nigella sativa oil had anti-inflammatory and antibacterial activities, reducing biofilm formation and disrupting the colonization of pathogenic bacteria essential for the progression of periodontal disease. Nigella sativa oil could offer an alternative therapy for treating gingivitis and may prevent associated systemic diseases and improve overall health outcomes.展开更多

[Methods]Gingival inflammation was established by LPS injection. Male SD rats were randomly divided into 7 groups: normal control group( no treatment group),solvent control group,model group( LPS injection),HLJD low dose group( 0. 25 g/kg),HLJD medium dose group( 0. 50 g/kg),HLJD high dose group( 1. 00 g/kg),and metronidazole and fenbufen capsule( MFC) group. Water intake and urine volume were observed through metabolic cage feeding; gingival tissue protein expressions were detected by LC-ESI-MS/MS method; oxidative stress-related molecules such as total superoxide dismutase( T-SOD) and hydrogen peroxidase catalase( CAT) were detected by the biochemical kit combined with a microplate reader; expressions of TSC related with energy metabolism-related signaling pathway were detected by western blotting. [Results]When rat gingivitis was injected by LPS,both water intake and urine volume were decreased,the levels of T-SOD and CAT were decreased,and the expressions of fructose-bisphosphate aldolase C,triosephosphate isomerase 1 and TSC2 were increased. Huanglian Jiedu Decoration can increase water intake and urine volume,increase the levels of T-SOD and CAT,reduce the expressions of fructose-bisphosphate aldolase C and triosephosphate isomerase 1,and inhibit the expression of energy metabolism-related pathway molecule TSC2. [Conclusions] Huanglian Jiedu Decoration can treat rat gingivitis through inhibiting energy metabolism and oxidative stress such as TSC signal pathway and glycolysis related molecules.展开更多

The disease is characterized by cutaneous, ocular, neurological and oral changes. Oral features in the form of early development of Squamous cell carcinoma, usually at the lower lip and tip of the tongue may be seen. The disorder is associated more commonly in populations where marriage of close blood relatives is common. Treatment of the disorder includes avoidance of Ultra violet radiation, topical application of 5 fluorouracil to treat actinic keratoses, and regular evaluation by an optholmologist, dermatologist, and neurologist. Genetic counseling is an important aspect as an increased incidence of consanguineous marriages have been reported with this disorder. Here, we report an interesting case of xeroderma pigmentosum in an 18 year old male patient who presented with characterstic desquamation of gingiva, fissured tongue and geoghraphic tongue.展开更多

文摘Objective: To assess the clinical anti-inflammatory and antimicrobial efficacy of Nigella sativa oil compared with chlorhexidine in patients with gingivitis. Methods: A double-blind, randomized clinical trial was conducted in patients having chronic generalized gingivitis. Patients were randomly assigned to receive Nigella sativa oil(n=18) or chlorhexidine(n=19). The following assessments were made on day 0 and day 15: plaque index, gingival index, gingival IL-6 and IL-18 levels were measured using ELISA, plaque colony-forming units, and alpha-hemolytic Streptococcus strains. Data were analyzed using parametric and non-parametric tests and Fisher’s exact test.Results: Both interventions reduced plaque index and gingival index scores(P<0.000 1). The Nigella sativa oil group was better at lowering IL-6(P=0.007 6) than the chlorhexidine group(P=0.145), although there was no change in IL-18 levels(P>0.05). The post-intervention plaque index and gingival index scores and inflammatory cytokine levels between the two groups were not significantly different. Both interventions caused a significant reduction in the plaque colony-forming units(P<0.000 1), reducing pathogenic bacteria: Streptococcus mitis, Streptococcus oralis, Streptococcus sanguinis, and Streptococcus parasanguinis in the chlorhexidine group(50%)(P=0.103 1), and the Nigella sativa oil group(20%)(P=0.739 5). Conclusions: Nigella sativa oil had anti-inflammatory and antibacterial activities, reducing biofilm formation and disrupting the colonization of pathogenic bacteria essential for the progression of periodontal disease. Nigella sativa oil could offer an alternative therapy for treating gingivitis and may prevent associated systemic diseases and improve overall health outcomes.

文摘[Objectives] To evaluate the effects of Huanglian Jiedu Decoration( HLJD) on the treatment of rat gingivitis with excess internal heat through injecting lipopolysaccharide( LPS) in tooth-supporting tissues. [Methods]Gingival inflammation was established by LPS injection. Male SD rats were randomly divided into 7 groups: normal control group( no treatment group),solvent control group,model group( LPS injection),HLJD low dose group( 0. 25 g/kg),HLJD medium dose group( 0. 50 g/kg),HLJD high dose group( 1. 00 g/kg),and metronidazole and fenbufen capsule( MFC) group. Water intake and urine volume were observed through metabolic cage feeding; gingival tissue protein expressions were detected by LC-ESI-MS/MS method; oxidative stress-related molecules such as total superoxide dismutase( T-SOD) and hydrogen peroxidase catalase( CAT) were detected by the biochemical kit combined with a microplate reader; expressions of TSC related with energy metabolism-related signaling pathway were detected by western blotting. [Results]When rat gingivitis was injected by LPS,both water intake and urine volume were decreased,the levels of T-SOD and CAT were decreased,and the expressions of fructose-bisphosphate aldolase C,triosephosphate isomerase 1 and TSC2 were increased. Huanglian Jiedu Decoration can increase water intake and urine volume,increase the levels of T-SOD and CAT,reduce the expressions of fructose-bisphosphate aldolase C and triosephosphate isomerase 1,and inhibit the expression of energy metabolism-related pathway molecule TSC2. [Conclusions] Huanglian Jiedu Decoration can treat rat gingivitis through inhibiting energy metabolism and oxidative stress such as TSC signal pathway and glycolysis related molecules.

Material and Methods: This study included 150 male participants. They were divided according to the levels into three equal groups: levels 5, 6, and 7 (group I), levels 8, 9, 10 (group II) and levels 11, 12, and interns (group III). This study consisted of questions related to age, gender, educational level, father’s education, mother’s education, home ownership, brushing teeth more than or twice a day, in addition to daily lifestyle habits that were daily smoking, daily use of sugary drinks, and daily use of sugary foods. Some clinical parameters of plaque-induced gingivitis and periodontitis and the percentage of radiographic bone loss were recorded. All data were collected and analyzed using Tukey’s test and Chi-square test. A P-value of less than 0.5 (p Results: One hundred fifty male dental students of different levels in the college of dentistry at King Khalid University participated in the study in three groups (I, II, and III). The mean age of group III is more than that of group II and group I, with highly statistically significant differences (p 30%) were more among the participants in group I than the participants in groups III and II. There was an increase in the percentage of affected participants with stages III and IV of clinical attachment loss (CAL), periodontal pocket depth (PPD), radiographic bone loss (%RBL), tooth mobility, as well as glycated hemoglobin (HbA1c) test values (>7%), and the number of cigarettes smoked per day (>10 cigs) in group III more than in group II and I. Conclusion: We conclude that the severity and grading of plaque-induced gingivitis were higher among the participants in group I, while the severity and grading of periodontitis were higher among the participants in group III due to the different impact of their daily lifestyle habits.
文摘In xeroderma pigmentosum, a rare genodermatosis, transmitted as an autosomal recessive disorder, excessive solar damage to the skin develops at an early age. The disease is characterized by cutaneous, ocular, neurological and oral changes. Oral features in the form of early development of Squamous cell carcinoma, usually at the lower lip and tip of the tongue may be seen. The disorder is associated more commonly in populations where marriage of close blood relatives is common. Treatment of the disorder includes avoidance of Ultra violet radiation, topical application of 5 fluorouracil to treat actinic keratoses, and regular evaluation by an optholmologist, dermatologist, and neurologist. Genetic counseling is an important aspect as an increased incidence of consanguineous marriages have been reported with this disorder. Here, we report an interesting case of xeroderma pigmentosum in an 18 year old male patient who presented with characterstic desquamation of gingiva, fissured tongue and geoghraphic tongue.

文摘Background:Observational studies have shown that inflammatory bowel disease(IBD),such as ulcerative colitis(UC)and Crohn disease(CD),is associated with gingivitis and periodontal disease(GP).This study aims to investigate whether there is a causal relationship between IBD and GP.Methods:This study assessed the causal relationship between IBD and GP through a two-sample Mendelian randomization(MR)study.The required data were obtained through the IEU OpenGWAS project.Instrumental variable screening and the MR and sensitivity analyses were performed using the“TwoSampleMR”R package.Results:IBD,UC,and CD may have a causal effect on GP(IBD,inverse variance weighting[IVW]OR=1.05,95%CI=1.00–1.10,P=0.03;UC,IVWOR=1.05,95%CI=1.00–1.11,P=0.03;CD,weighted median OR=1.06,95%CI=1.00–1.13,P=0.04;simple mode OR=1.15,95%CI=1.02–1.31,P=0.03).Scatterplots,forest plots,and funnel plots showed a significant relationship between IBD and GP and confirmed the robustness of the model.In sensitivity testing,no horizontal pleiotropy or heterogeneity was found in this study.Conclusions:This study found a possible causal relationship between IBD(UC and CD)and GP,which deserves to be considered in clinical practice.
文摘目的研究成纤维细胞生长因子18(FGF18)是否能诱导体外分离培养的人牙龈成纤维细胞(HGFs)向成骨样细胞分化,并探究其成骨机制。方法组织块法分离培养HGFs并鉴定。取第3代HGFs,分为实验组和对照组。实验组加入FGF18和L-DMEM、对照组加入L-DMEM。噻唑蓝(MTT)法检测不同浓度FGF18(0、0.01、0.02、0.04、0.06 mg/L)对HGFs增殖影响;碱性磷酸酶(ALP)和茜素红染色检测成骨能力和矿化能力;RT-PCR、免疫细胞化学染色及Western blot检测成骨相关基因、蛋白和BMP信号通路中BMP2基因和蛋白表达情况。结果与对照组比较,实验组培养3、5、7、9、11 d均可促进HGFs增殖(P<0.05);培养14、21 d ALP活性、矿物盐沉积均增高(P<0.05),ALP、OPN、OCN及BMP信号通路中BMP2 mRNA表达均明显增高(P<0.01)。培养21 d OPN、OCN及BMP2蛋白表达较培养14 d明显增高(P<0.01)。结论FGF18能促进HGFs增殖,诱导HGFs向功能性成骨样细胞分化,其成骨机制与上调BMP2有关。
