Active clinical trials for "Periodontitis"

Treatment of periodontal diseases is influenced by several risk factors. Psychological stress is considered as one of them. Aim of this study is to assess if stress influences results of non surgical periodontal treatment in severe chronic forms of periodontitis.

Periodontitis is a widely prevalent disease worldwide that has serious public health consequences. Its prognosis includes tooth loss and edentulism, a condition that negatively affects chewing causing functional disability; and esthetics causing social impairment. Consequently, periodontitis may end up causing marked impairment of the quality of life of the affected patients, impairment of general health and increasing the dental care costs significantly. Changes in the oral mucosa arise by primary products resulting from tissue breakdown due to gingivitis. It then triggers the host cells to produce proteinases that mediate loss of marginal periodontal ligaments, apical migration of the junctional epithelium and apical spread of bacterial biofilm. Therefore, this research aims to identify the risk of smoking to both periodontitis and oral cancer, and the risk of periodontitis to oral cancer.

To compare the diagnostic accuracy of extra-oral x-rays with intra-oral x-rays, in contrast to clinically observed measurements, for the detection of calculus and bone loss of either the suprabony or infrabony types in patients undergoing periodontal surgery.

Rheumatoid arthritis and periodontitis are two inflammatory diseases that share many pathophysiological similarities as some inflammatory mediators like TNF-alpha, IL-1, Il-6, Il-17, Il-12 et Il-17, RANK-L, or OPG The most severe or progressive forms of rheumatoid arthritis require in 10-30% of cases, the use of biotherapies such as anti-TNF-alpha, anti CD-20 and anti-lL-6. All these treatments results in, among other things, an increased risk of infection, both viral and bacterial. These new biotherapies could have an impact on periodontal status either by favouring sub gingival colonization of root surfaces by periodontal pathogenic bacteria and initiate periodontitis or exacerbate pre-existing periodontitis, or a positive modulation of the host response by inhibiting bone resorption of the alveolar process. To date, very few studies have been conducted on this subject which is really a translational research, involving several medical specialties.

The main objective of this study is to assess whether Periodontal Disease is more prevalent in adult patients diagnosed with Alzheimer's Disease compared to adult patients without Alzheimer's Disease. The secondary objective is to describe and characterize the microbiological and biochemical profile of adult patients diagnosed with Alzheimer's Disease and compare with adult patients without Alzheimer's Disease.

Patients diagnosed with stage III or IV periodontitis during routine visits at the department of periodontology will undergo a validated questionnaire to understand the impact of the disease on their quality of life.

Due to the phenomenon of bacterial resistance, photodynamic therapy (PDT) has been studied as an alternative to the use of antibiotics on the periodontal treatment. However, the studies show several discrepancies between the parameters adopted for PDT, which makes it difficult to compare the results and measure their efficacy. The objective of this research was to investigate the tissue dosimetric parameters used in PDT for the treatment of periodontal disease. In order to achieve this objective, the scattering pattern of light in periodontal tissue, the concentration of methylene blue in the periodontal pockets and the number of viable microorganisms were evaluated. This clinical trial included 30 patients with chronic periodontitis according to the eligibility criteria. The patients were in periodontal treatment at the Dental Clinic at the University of Nove de Julho, where the research was carried out. Three incisors from each patient were selected for the experimental procedures. The pattern of light scattering was observed through intraoral photographs. A laser with emission of radiation with wavelength of 660 nm and 100 mW of power was used. The concentration of the photosensitizer (PS) in the periodontal pockets was evaluated by spectrometer before irradiation. Methylene blue was used as PS at the concentration of 100 μM in two different formulation and vehicles to evaluate the drug dimerization. Then, the procedures of irradiation of the PDT were carried out, with 3 irradiation times of 1, 3 and 5 min. The microbiological evaluation was performed from subgengival biofilms of the periodontal pockets of the experimental sites, before and immediately after the irradiation procedures.

The aim of our study is to determine the interleukin-1βeta (IL-1β), interleukin-8 (IL-8) and tumor necrosis factor-αlfa (Tnf-α) levels in gingival crevicular fluid (GCF) and clinical periodontal parameters following the treatment with Erbium,Chromium:Yttrium-Scandium-Gallium-Garnet (Er,Cr:YSGG) and diode lasers in adjunct to scaling and root planing (SRP) in patients with generalized aggressive periodontitis (GAgP). Twenty-six patients with GAgP (n=26) were enrolled in the study. The study was designed as a "split-mouth" study. In each patient, three quadrants were randomly determined as SRP-control, SRP+Er,Cr:YSGG and SRP+Diode laser. Clinical periodontal measurements were recorded at the baseline and third month after the treatment. Cytokines levels in GCF were determined by enzyme-linked immunosorbent assay (ELISA).

Aim: This study compared the effectiveness of three different mouthrinses (alcohol and non-alcohol chlorhexidine, alkyl dimethyl glycine / alkyl dimethyl amine oxide - C31G) in plaque control and early wound healing, postoperatively. Materials and Methods: In this, randomized, double-blind, controlled clinical trial 42 patients were allocated to three groups assigned to two weeks rinsing after periodontal surgery with C31G (group A), alcohol-free chlorhexidine 0.12% (group B) or alcohol-based chlorhexidine 0.12% (group C). At weeks 1 and 2, plaque and early wound healing indices were recorded. At day 14, total bacterial counts were estimated utilizing real - time qPCR. Statistics included linear and generalized linear mixed models.

The present study was done to evaluate the effect of clarithromycin as an adjunct to scaling and root planning at baseline, three months and six months intervals . Clinical, microbiological and immunological parameters were taken. Clinical parameters include gingival index , probing depth and clinical attachment level. In the present study, improved clinical and microbiological outcomes were attained using adjunctive clarithromycin, including GI, PD reduction, CAL gain and reductions in the frequency of detection of C-reactive protein, Pg, Aa. These results together with the recommended easy dosage and limited side effects make the use of this antibiotic in the treatment of periodontitis patients but only for a shorter period of time.
