Filter by:Inflammatory process begins around root apex as a result of bacterial infection of pulp cavity in chronic apical periodontitis. Bone destruction can begin in apical region after immunological reactions at the end of inflammatory process, and radiolucent periapical lesion seems in this way. If bone destruction around apical region is in the rate of 30%, we can notice this difference eventually. Histological manifestations of periapical inflammation can be observed in the result of pulp necrosis and inflammation around apical region. Mocelular methods can determine the type of therapy in various diseases. Each region and tissue reserve specific host factors. Vast majority of pulpal inflammation was trigerred by microorganisms. Certain bacterial virulence factors may damage host tissue directly, other virulence factors can stimulate prolonged non-specific immune response causing tissue damage. In the last phase of infection, immunopathological destruction of pulp tissue is observed due to humoral response. IL-17 is an important inflammatory cytokine released from T cells of the immune system. TNF-alpha and RANKL are also mediators responsible for bone destruction metabolism. TNF is a cytokine mediating immunologic changes during periodontal disease. TNF induction stimulate secondary mediators taking part as chemotactic cytokines. TNF has two different types; TNF-alpha and TNF-beta. TNF-alpha is a polypeptide cytokine produced by macrophages and monocytes. TNF-alpha stimulates bone resorption . There has been limited researches analyzing GCF, blood and tissue of pulp, dentin-derived fluid and periapical fluid for molecular diagnosis so far. GCF is a fluid derived from gingival groove. This fluid contains a lot of host factors such as anticor, bacterial antigen, protein and cytokines. GCF sampling is a non-invasive method, it can be used to provide diagnostic information in all clinical cases. In this study, we will evaluate the levels of IL-17, TNF-alpha and RANKL in the gingival crevicular fluid of teeth with periapical lesion diagnosed with chronic apical periodontitis. Thus, it will be evaluated whether these markers can be used for diagnosis and follow-up of the disease in teeth with periapical lesions.
Vegetables, mainly green leafy ones and some others like beets, are a rich source of nitrate. Nitrate metabolism has shown benefits to the body and there are recent studies that agree that the consumption of nitrates from vegetables can modify the oral microbiota by increasing species with nitrate-reducing capacity, which are also bacteria that are associated with oral health.
Chronic Periodontitis is an inflammatory condition and a common disease worldwide. Honey has been used in dentistry for its beneficial properties. It has been used in many oral conditions like gingivitis and periodontal diseases for its antibacterial and healing properties, on the other hand, aloe vera gel is known for its anti-inflammatory aspects, and it has been used in dentistry for its potential advantages. Objective The main objective of the study was to find out the effects of gingival massage with aloe-vera gel and sidr honey as adjunct to non surgical therapy after one month in patients with Chronic periodontitis and to find out whether there is a difference in the efficacy of aloe-vera gel and sidr honey in reducing plaque index, gingival index, pocket depth and bleeding on probing after one month of gingival massage when used as adjunct to non-surgical therapy. Method 105 patients with chronic periodontitis were selected in this single-blinded Randomized control clinical trial. At recruitment non-surgical therapy i-e scaling and root debridement was performed. At baseline all clinical parameters, gingival index, plaque index, bleeding on probing and pocket depths were recorded. All the participants were then randomly divided in three groups, Group A: SRD & Gingival massage with Aloe-vera gel, Group B: SRD & Gingival massage with Sidr honey and Group C SRD only. On 30th day of trial all the patients were re-examined for all the clinical parameters. Statistical Analysis SPSS version 21 was used for data entry and analysis with significance level set at Ƥ <0.05. Median, median difference and Inter Quartile ranges were reported for plaque index, gingival index, probing depth and percentages were reported for bleeding on probing. Wilcoxon Signed rank test was used for pre and post comparison. Mann Whitney test was applied for comparison between groups.
Evaluate the 10-year stability clinical, radiographic outcomes obtained with the application of the modified minimally invasive surgery to deep pockets associated with intrabony defects.
1. Primary objective To measure the gingival crevicular levels of A.actinomycetemcomitans and P.gingivalis after intra-pocket application of diode laser in severe periodontitis (stage 3 grade C) patients. 2. Secondary objective To compare the levels of the same microorganisms as in cases of diode laser therapy to those after conventional treatment with systemic antibiotic administration in severe periodontitis (stage 3 grade C) patients. 3. to measure clinical parameters probing depth,attachment loss and mobility grade
The aim of this prospective cohort observational study is: (i) to assess the endodontic treatment outcome in a private specialist endodontic office in Slovenia; (ii) to estimate the effect of various pre-, intra- and postoperative factors onto endodontic treatment outcome.
The Er:YAG laser possesses specific characteristics allowing to be used in non-surgical periodontal treatment. The aim of the resent study was to evaluate the long-term clinical effectiveness of Er:YAG laser monotherapy in the treatment of moderate chronic periodontitis and to compare it with conventional hand instrumentation. MATERIALS AND METHODS: 451 teeth (1,099 periodontal pockets) from 30 patients with moderate chronic periodontitis (initial probing pocket depth 4 to 6 mm) were allocated for subgingival scaling and root planing in two groups - hand instrumentation (control) and Er:YAG laser instrumentation with 100mJ/15Hz (test). Using a computerized periodontal probe, patients were examined for probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL), bleeding on probing (BOP), plaque presence (FMPS) at baseline, one, three, six and 12 months after instrumentation.
The aim of the research will be to compare periodontal status and level of antioxidants in unstimulated saliva of systemic sclerosis patients with periodontitis and systemically healthy periodontitis patients. Twenty systemic sclerosis patients with periodontitis (SS group) and twenty systemically healthy periodontitis patients (P group) will be enrolled in the present study. The results may indicate higher periodontal destruction and antioxidant perturbations in unstimulated saliva of systemic sclerosis patients with periodontitis compared to systemically healthy periodontitis patients.
Aims are to assess periodontal health and salivary stress/ immunity responses in COVID-19 survivors
This is a pilot diagnostic accuracy study to assess the ability to discriminate in a screening context Stage IV periodontitis from other stages of periodontitis. The index test is the assessment of masticatory dysfunction performed with a questionnaire and a chewing gum test. The reference standard is a full periodontal and functional assessment performed by a trained and calibrated specialist.
