Active clinical trials for "Periodontal Diseases"

The study will cover 80 patients under 70 years of age. Initially they will be assigned to three groups: patients generally healthy with periodontitis (P), patients after myocardial infarction with periodontitis (CP) and patients generally healthy with a healthy periodontium (H). Periodontal examination will be performed before treatment, 2 weeks and 3 months after the treatment with a Williams probe calibrated at intervals 1-2-3-5-7-8-9-10mm. Pocket depth (PD), clinical loss of the attachment (CAL) bleeding on probing (BOP), plaque control record (PCR) measurements will be performed. Clinical data will be collected at six sites per tooth (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, and distolingual) of the designated study teeth. PD will be measured in millimeters from the free gingival margin to the base of the probable pocket using a periodontal probe. The presence of BOP will be determined as being present or absent (+/-) within 30 seconds after probing. CAL will be defined as the distance from the cementoenamel junction to t the base of the probable pocket . Patients within CP and P groups will be randomly assigned to one of the two groups (study group and control group) and an later visit will be scheduled. Before treatment, teeth will be rinsed and the study areas will be isolated with cotton rolls and dried gently. Supragingival plaque will then be removed with a sterile curret without coming into contact with the gingiva. GCF samples will be collected from the deepest single root tooth pockets previously identified. The sample will be collected from the deepest pocket using the Periopaper strips (OraflowInc., USA). Before collecting the material, the teeth will be insulated with cotton swabs. The teeth will then be dried with air. The strips will be placed in pockets until a slight resistance is perceived, and they will be left in place for 30 seconds and then transferred to Periotron 8000 (OraflowInc., USA) for the determination of fluid volume. Strips contaminated by bleeding will be discarded. Next, each strip will be inserted into the Eppendorff tube and sent to the laboratory at the Medical Analytics Department of PUM in Szczecin for further analysis. The volume of the gingival fluid will be given in μl, in accordance with the conversion of values displayed as a reading on the device. The microbiological examination (via Real-PCR method) for the presence of pathogenic bacteria for periodontium will be performed using commercial standard sets PET-MIP deluxe ® (MIP Pharma). Samples will be taken from the patient's deepest periodontal pocket. After isolation of the examined tooth from the access of saliva, sterile paper will be placed inside the pocket for 10 seconds following transfer to the transport containers included in the PET-Mip deluxe ® kits and sent to the MIP-Pharma laboratory in St. Ingbert in Germany. In the control and study group, supra and subgingival scaling and root smoothing with Gracey currets will be performed. Individual oral hygiene instructions will also be given to each patient. In addition laser therapy of the pockets with a 980nm diode laser will be carried out in the study group. The levels of TC, LDL, HDL, TG, hsCRP, leukocytes, fibrinogen, OB, IL-6, AST, ALT in the peripheral blood will be marked three times (before treatment, 2 weeks and 3 months post treatment). For this purpose, the blood will be taken from the superficial veins of the forearm and sent for further analysis at the Medical Analytics Department of PUM in Szczecin.

The purpose of this study is to investigate the effect that obesity may have on the nonsurgical treatment (with and without the adjunct use of metronidazole) of destructive periodontal diseases (chronic periodontitis).

Hypothesis: Women who use Actonel (risedronate) for osteopenia will show beneficial periodontal effects.

Periodontitis is common in patients with cirrhosis and may lead to systemic sepsis. 1 Grønkjær et al demonstrated that severe periodontitis predicted higher mortality in patients with cirrhosis. 2 In India, the wide use of oral tobacco, smoking and poor dental hygiene fosters a dual hit to the outcomes of liver disease especially in the setting of liver transplantation. However, a causal relationship between the oral microbiome and liver disease and outcomes is a matter of conjecture. Oral bacterial diseases, such as caries and periodontitis are caused by a consortium of bacteria rather than a single species. These constitute opportunistic infections that occur under the proper circumstances and conditions, e.g., diet, host immune response, complicating systemic or genetic disorders, pH, poor oral hygiene and lifestyle. It is well known that specific bacterial taxa that colonize the oral cavity are associated with oral health and oral diseases or afflictions, such as dental caries, periodontal diseases, endodontic lesions, dry socket, halitosis, and odontogenic infections. Bajaj et al have demonstrated systematic periodontal therapy in cirrhotic outpatients improved endotoxemia, as well as systemic and local inflammation, and modulated salivary and stool microbial dysbiosis over 30 days. Bajaj et al performed another study on comparison of oral and gut microbiota in patients with and without hepatic encephalopathy. There were differences in salivary microbiota composition and inflammatory markers between controls and cirrhotics. The association between periodontitis, oral dysbiosis and the prognosis of cirrhosis remains crucial with relevance to situations like acute-on-chronic liver failure and other inflammation-related adverse events.

To evaluate the effect of adjunctive systemic administration of melatonin to mechanical non- surgical periodontal therapy in obese patients with periodontitis.

Literature shows the potential effectiveness of L. reuteri as an adjunct to non-surgical periodontal therapy in initial treatment of periodontitis, but also underlines the limits of the conclusions, and the heterogeneity and limited sample size of the available studies. Therefore, there is a need for longer-term, randomized, controlled studies. Moreover, only one study addresses the use of this probiotic during the supportive therapy, in particular in patients with severe forms of periodontitis, and only few patients were included. Patients meeting the criteria of periodontitis stage III and IV, grade C are considered to be affected by severe and advanced forms of periodontitis with a rapid rate of progression. This group of patients could particularly benefit from supplements for the maintenance of periodontal health. The hypothesis of the present randomized controlled trial is that the adjunctive use of probiotic treatment can bring clinical and microbiological advantages during the supportive therapy of periodontal disease, and reduce the number of residual pockets. To test this hypothesis, the patients, upon initial evaluation, will be divided in 2 study groups and, after a session of professional oral hygiene, will be prescribed one of the therapies below: PLACEBO: The patients of the control group will receive control lozenges without live bacteria; TEST: The patients of the probiotic group will receive probiotic lozenges containing Lactobacillus reuteri DSM 17938 and Lactobacillus reuteri ATCC PTA 5289 (a minimum of 2 × 108 colony-forming units L. reuteri Prodentis/lozenge, BioGaia AB). The probiotic and control lozenges will be identical in taste, texture and appearance. The lozenges will be given to all patients to consume at home. The patients will be instructed to dissolve them on their tongue twice a day, preferably after brushing, for 3 weeks. Periodontal and microbiological parameters will be evaluated at 3 and 6 months after the initial therapy, and compared between the two groups.

Periodontal disease is a gum infection caused by plaque on teeth containing both bacteria and calculus (hard) deposits. These need to be removed on a regular basis to maintain gum health and to prevent teeth weakening. A routine cleaning procedure, scaling/root planing, is accompanied with post-operative soft tissue tenderness and teeth sensitivity making oral hygiene maintenance difficult during wound healing. The need for novel therapeutic approaches, such as cyanoacrylate adhesives, has been identified. It has been hypothesized that its application may provide comfort and assist patients with their daily oral self-care procedures following teeth cleaning.

This study is to verify the efficacy of tobacco cessation in patients with oral diseases; periodontitis, dental implant and oral mucosal diseases by a multicenter prospective trial. Tobacco cessation intervention is implemented for 12 weeks. During the tobacco cessation intervention for the subjects, attending doctors implement standard treatments for their oral diseases. Improvement of each disease is evaluated between smoking cessation intervention group and non-cessation intervention group.

The purpose of this study is to learn if a chair-side testing device will accurately measure levels of a salivary biomarker and thus indicate if a patient has periodontal health, gingivitis or periodontal disease.
