Active clinical trials for "Periodontal Diseases"

The aim of this study is to determine the concentrations of Visfatin, Fetuin-A and Sirtuin 1 in the gingival crevicular fluid and clinical periodontal parameters in diabetic and systemically healthy individuals and to determine whether non-surgical periodontal treatment had any effect on these biomarkers and periodontal clinical parameters at the end of a 3-month follow-up period. The hypothesis of our study is that gingival crevicular fluid Visfatin, Fetuin-A and Sirtuin 1 concentrations will change with non-surgical periodontal treatment in type 2 diabetic and systemically healthy individuals and that this change will be associated with diabetes and clinical parameters.

Objective: The objective of this research was to compare the effect of a single session supragingival scaling in a group of pregnant women with periodontal disease with a group that received supra and subgingival scaling. Methods: The investigators included 34 pregnant women between 15 and 43 who had at least 4 teeth with probing depth ≥ 4 mm or clinical attachment loss ≥ 3 mm, with bleeding on probing in the same place. Women were divided into two groups, the group 1 received supra and subgingival scaling associated with oral hygiene orientation (OHO) and the group 2 received only supragingival scaling with OHO too.

The primary objective of this study is to assess the short-term immune response of type-2 diabetics with generalized chronic periodontitis (GCP) to nonsurgical periodontal treatment. The investigators hypothesize that type-2 diabetes exacerbates the disruption of DC (dendritic cells)-mediated immune homeostasis associated with periodontitis.

The purpose of this study is to determine the effect of gum infection on parameters of cardio-vascular disease.

The purposes of this study are to: compare the clinical effectiveness of a traditional and a medical model of periodontal therapy; and determine the value of the two approaches to periodontal therapy.

In Phase II trials, treatment with ketorolac tromethamine oral rinse has been shown to block periodontal disease progression even in the absence of standard clinical intervention such as scaling and root planing which is routinely done to reduce the periodontal pathogen load that is driving the local destructive host inflammatory response. Resolution of periodontal disease has a favorable effect on normalizing the cellular and biochemical indices of inflammation as reflected by histological changes as well as the levels of prostaglandin E2 (PGE2) and interleukin I beta (IL-1beta). In this trial, we will prospectively evaluate if eliminating the inflammatory process (via inhibition of PGE2 biosynthesis) in the oral cavity has a favorable impact on reversing oropharyngeal leukoplakia. To test this hypothesis, up to 57 prospectively identified individuals with objective findings of oropharyngeal leukoplakia will be randomized to receive either a mouth rinse containing ketorolac or placebo. Ketorolac is a 7-fold selective inhibitor of cyclooxygenase-2 (Cox-2), which has been designed for local delivery to maximize the drug exposure to critical oral target tissues while minimizing gastric and systemic exposure to the drug. All responses will be determined at the three month completion of trial using the response criteria developed at MD Anderson Cancer Center. The drug will be given for three months and then all the patients will be followed for one additional month off all oral treatment to observe for late side effects. Based on the analysis of oral exam and photographically documented change in the pretreatment area of leukoplakia, the response of all patients will be determined. The evaluation of the outcome will include a measurable secondary endpoint consisting of an assessment of histological change as determined by serial punch biopsies of the oral cavity. In addition, a panel of carcinogenesis and inflammatory markers will be serially measured at baseline, at one month follow up or at study conclusion. In the residual tissue, other bioassays will be evaluated to determine their suitability as intermediate endpoint markers. The purpose of this study is a preliminary evaluation of the effectiveness of ketorolac as a potential chemoprevention agent for oropharyngeal cancer. If ketorolac administration in this preliminary Phase IIB trial is associated with reversal of leukoplakia, then a definitive Phase III chemoprevention trial with a cancer reduction endpoint (most likely in a cooperative group-type setting) may be the next validation step.

The primary objective of this controlled clinical trial is to evaluate the clinical effect of systemic amoxicillin plus metronidazole therapy in conjunction with initial non-surgical treatment of peri-implantitis. The secondary objective is to assess the microbiological effectiveness of this peri-implantitis treatment approach. The present study is a single-blind, randomized controlled clinical trial. Adult patients with at least one endosseous implant in the oral cavity with clinical and radiographical evidence of periimplantitis will be included in this study. Patients with implants affected by peri-implantitis will receive initial periodontal treatment existing of oral hygiene instructions and mechanical cleansing of both implants and remaining dentition. Immediately after initial periodontal therapy patients will be instructed to rinse their mouth with 0.12% chlorhexidine + 0.05% cetylpyridinium chloride without alcohol twice daily during 30 seconds for 2 weeks. Additionally patients will receive a recipe for medication consisting of 500 mg amoxicillin and 500 mg metronidazole to be taken every 8 hours for the following 7 days or no recipe. The main study parameter is the mean peri-implant bleeding score.

This study compares the efficacy of root coverage achieved by the Pinhole Surgical Technique (PST) technique and the Connective Tissue Graft (CTG) technique in the treatment of Miller class I and II gingival recession defects. All patients will receive PST in one quadrant and CTG in another quadrant. The hypothesis being tested is: Pinhole Surgical Technique outcomes are not inferior to those of the Connective Tissue Graft surgical technique.

The aim of this study is to compare quadrant scaling and root planing (Q-SRP) versus full-mouth treatment (FM-SRP) in terms of acute-phase responses following no surgical periodontal treatment in obese patients affected by periodontitis.

Unfavorable systemic conditions condition a low resistance of the host to the virulence of the aggressive agent, causing in a periodontal disease and may lead to difficulties in the therapeutic response. The longer the duration of diabetes, it is suggested that greater severity of periodontal disease and loss of insertion. The objective of the present study will be to evaluate the clinical, microbial and immunological characteristics in diabetic subjects with chronic periodontitis submitted to non-surgical periodontal treatment. Will be 120 individuals with chronic periodontitis, including 60 type 2 diabetic subjects and 60 healthy should receive and have access to the informed consent form. Medical and dental clinical examination should be performed and evaluation microbial and immunological properties of gingival fluid and saliva respectively. Non-surgical periodontal therapy with subgingival scaling should be performed in all individuals who will be evaluated at two times: at the beginning and after 90 days of the periodontal therapy with new performing clinical exams and collecting oral samples, oral hygiene instructions will be addressed in two sessions. The data will be subjected to appropriate statistical tests and shall provide a comparison between the times. There seems to be a relationship between type 2 diabetes and periodontal disease and studies that provide the implementation of therapy are essential for clarifying the relationship.
