Filter by:Intrinsic apoptosis pathway plays a critical role in the host immune defense and inflammation and its dysregulation is involved in various chronic diseases. Bcl-2 protein family primarly mediates this mitochondrial pathway. This study aimed to investigate the pro-apoptotic Bax and anti-apoptotic Bcl-xl levels and their association with interleukin-22 (IL-22) and transforming growth factor-beta 1 (TGF-β1) in gingival crevicular fluid (GCF) of patients with periodontitis. In total 75 systemically healthy and non-smoker individuals consisting of stage III periodontitis (n=23), gingivitis (n=26), periodontally healthy (n=26) were enrolled. Whole-mouth clinical periodontal measurements were recorded. Bax, Bcl-xl, IL-22 and TGF-β1 levels in GCF were determined by ELISA. Data were analyzed using non-parametric statistical tests.
The present study aimed to determine the effect of non-surgical periodontal treatment on serum and salivary SIRT-1, MMP-9, and T-SOD levels in periodontitis stage III grade B (P-III-B) and C (P-III-C) patients. 17 periodontally healthy, 16 P-III-B and 16 P-III-C subjects were enrolled. At baseline, serum and saliva samples were collected and the whole mouth clinical periodontal parameters were recorded. Periodontitis patients received non-surgical periodontal treatment. Clinical parameters were re-measured and samples were re-collected at 3 months after treatment. Serum and salivary SIRT-1, MMP-9, and T-SOD levels were analyzed by ELISA. Data were analyzed using appropriate statistical tests.
Activin-A belongs to the transforming growth factor-beta superfamily and is a multifunctional cytokine that plays a role in inflammation, immune response, tissue repair and regeneration. Proinflammatory cytokine interleukin-1beta (IL-1β) can increase Activin-A expression in various cell types. This study aims to evaluate gingival crevicular fluid (GCF) and salivary Activin-A and IL-β levels in stage III periodontitis. Seventy-five systemically healthy and non-smoker volunteers consisting of 23 stage III periodontitis, 26 gingivitis and 26 periodontally healthy were enrolled. Full-mouth clinical periodontal indices were recorded, unstimulated whole saliva and GCF samples were obtained, Activin-A and IL-1β total amounts were determined by enzyme-linked immunosorbent assay. Statistical comparisons were performed using non-parametric tests.
Mothers usually have the primary role in bringing up children and developing health-related behaviors. The aim of this study was to determine the effect of mothers' dental anxiety and oral hygiene on the dental anxiety and periodontal health of their children. The study included 280 randomly selected children, aged 4-12 years, who came to the dentist for the first time and their mothers. Demographic and oral hygiene information of the mothers was collected through a questionaire. Dental anxiety of the mothers and children was assessed using the Modified Dental Anxiety Scale (MDAS) and the Venham Picture Test (VPT), respectively.
The present study aimed to assess the effect of non-surgical periodontal treatment on gingival crevicular fluid (GCF), saliva, and serum IL-26, IL-6, and IL-10 levels in stage III grade B periodontitis (SIII-GB-P) and C periodontitis (SIII-GC-P) patients. 25 periodontally healthy, 25 SIII-GB-P, and 25 SIII-GC-P participants were enrolled. At baseline, GCF, saliva, and serum samples were collected and the whole mouth clinical periodontal parameters were recorded. Periodontitis patients received non-surgical periodontal treatment (NSPT). Clinical parameters and samples were re-collected at 1 and 3 months after NSPT. GCF, saliva, and serum IL-26, IL-6, and IL-10 were analyzed by ELISA. Data were analyzed using appropriate statistical tests.
The present study aimed to assess the effect of non-surgical periodontal treatment on serum and salivary MMP-8, MAF, MIP-1α, M-CSF, and IL34 levels in periodontitis stage III grade B (P-III-B) and C (P-III-C) patients. 20 periodontally healthy, 20 P-III-B and 25 P-III-C participants were enrolled. At baseline, serum and saliva samples were collected and the whole mouth clinical periodontal parameters were recorded. Periodontitis patients received non-surgical periodontal treatment. Clinical parameters were re-measured and samples were re-collected at 1 and 3 months after treatment. Serum and salivary MMP-8, MAF, MIP-1α, M-CSF, and IL34 levels were analyzed by ELISA. Data were analyzed using appropriate statistical tests.
Hypoxia-inducible angiogenic pathway involving hypoxia inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF) and tumour necrosis factor- alpha (TNF-α) may regulate the several biological processes related to inflammation. Generalized aggressive periodontitis (G-AgP) is a rare but highly destructive form of inflammatory periodontal disease. The present study aimed to assess the effect of non-surgical periodontal treatment on gingival crevicular fluid (GCF) HIF-1α, VEGF and TNF-α levels in G-AgP patients. 20 G-AgP and 20 periodontally healthy subjects were enrolled. At baseline, GCF samples were collected and whole mouth clinical periodontal parameters were recorded. G-AgP patients received non-surgical periodontal treatment. Clinical parameters and GCF cytokines were re-measured at 1 and 3 months after treatment. GCF HIF-1α, VEGF and TNF-α levels were analyzed by ELISA. Data were analyzed using appropriate statistical tests.
This study investigates the salivary LL-37 in passive smoking-exposed and unexposed children and the association between salivary LL-37 levels and periodontal clinical parameters in these children.Unstimulated salivary samples were collected from 180 children (90 passive smoking-exposed and 90 passive smoking-unexposed)
Participants will be recruited for inclusion at a routine adjustment appointment prior to planned removal of the appliances. Following removal of the appliances, consenting participants will be randomly allocated to one of two groups by computer-generated random allocation. Allocation will be concealed from the treating clinician using of an opaque sealed envelope system. Standard stone model records will be available for all participants following removal of the appliances (T0). Participants in both groups will have follow-up scheduled for 3 (T1), 6 (T2) and 12 (T3) months following removal of the braces. All participants will be instructed to wear standard clear, plastic (Essix-type) retainers on a full-time basis for 6 months, followed by night-time wear for a further 6 months. A micro-electronic timer will be integrated within the upper Essix-type retainer. All participants will be given standard advice at each recall visit. Participants in the intervention group will receive tailored electronic reminders in the form of a mobile application. The frequency and content of the reminders will be informed by qualitative interviews involving participants from an allied trial, and from posts related to orthodontic retainers shared on social media. Instructions on the necessary duration of retention, maintenance of retainers, departmental details, allied to advice on appropriate management for appliance breakages, and delineation of the implication of suboptimal retainer wear will be included. Also, information related the debond visit and maintenance of optimal oral hygiene levels will be incorporated in the mobile application. Participants in the control group will not receive additional reminders. Treating clinicians will be kept blind to the study group. All patients failing an appointment will be sent another. Those wishing to withdraw from the trial may do so at any point without affecting continuing care with records taken at the point of withdrawal from the study with data analysis on an intention to treat basis. Thereafter, patient experiences with electronic reminders will be evaluated on a subset of participants using one-to-one interviews.
Some probiotics have been shown to have preventive effects on infectious diseases and allergies. Because their long-term enhancement of the immune responses of children, they have been recommended for infants in some countries. The most promising ones seem to be the combination of Bifidobacterium lactis BB-12 and Lactobacillus rhamnosus GG. Probiotic microbes are mainly ingested orally and the gastrointestinal tract is thus the primary target organ for them. However, the mouth is the first part of the gastrointestinal tract. Most probiotics are in theory cariogenic, thus their effects on oral health should be known. Several probiotics decrease levels of salivary mutans streptococci (MS), but in other respects very little is known about their effects on the oral microbiota. Also effects of probiotics on dental plaque should be studied. This study aims to find out the effects of the combination of BB-12 and LGG, delivered with a lozenge (4 weeks, twice a day) with a mixture of them on the amount of plaque and gingival health
