Active clinical trials for "Periodontitis"

Aim: The aim of this study was to examine post-operative pain (PP) severity after conventional irrigation and sonic activation methods, with and without laser disinfection in mandibular molar teeth diagnosed with symptomatic apical periodontitis. Methods: In total, 80 patients with symptomatic apical periodontitis were included in this randomized clinical study. There were four different irrigation and disinfection groups. In group 1, conventional irrigation only was applied. In group 2, EDDY (VDW, Munich, Germany), a sonic irrigation activation system, was applied. In groups 3 and 4, irradiation with a 980-nm diode laser was performed, following irrigation with the conventional method (needle irrigation) and EDDY (VDW) irrigation system, respectively. PP was assessed using a visual analogue scale (VAS). The patients were instructed to record their PP using this scale 8, 24, 48 hours and 7 days post-procedure, in addition to their analgesic intake. A chi-square test, Fisher's exact chi-square test and Fisher-Freeman-Halton exact test were used to assess qualitative data. Inter-group and intra-group parameters were assessed using the Kruskal-Wallis test and Wilcoxon's test at a significance level of p < 0.05 (for both).

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.

It is the aim of the study to evaluate the efficiency of "One stage full mouth disinfection" according to the original protocol (Quirynen et al. 1995) in comparison to other approaches considering different scaling strategies and different disinfection concepts. Therefore, a multicenter randomized control treatment will be performed. In total, 204 patients with chronic periodontitis shall be allocated to the following treatment concepts. Group A: quadrant scaling with weekly intervals (Q-SRP; N = 51); Group B: full mouth scaling (FMS; N = 51); Group C: full mouth disinfection (FMD; N = 51); Group D: full mouth disinfection with subgingival glycine air polishing using erythritol powder (FMDP; N = 51). Evaluation of periodontopathic parameters and periodontal pathogens at baseline, 3 months and 6 months shall give evidence about the benefits of concept and the single components of FMD.

Periodontitis is a multifactorial disease that can lead to the destruction of supporting tissues of the teeth resulting in pocket formation, recession or both. Since the primary etiological factors for periodontal disease are bacteria in supra and sub gingival biofilm, efforts for disease prevention and treatment are mainly focused on pathogen reduction and strengthening of epithelial barrier, thus contributing to decreased susceptibility to infection. Due to emergence of antibiotic resistance and frequent recolonization of treated sites with pathogenic bacteria, there was need for a new treatment paradigm to be introduced to periodontal disease. The need was fulfilled by the introduction of Probiotics and Bacterial Replacement Therapy. The term probiotic is derived from the Greek, meaning "for life" are microorganisms proven to exert health promoting influences in humans and animals. Food and Agriculture Organization and WHO have stated that there is potential for probiotic foods to provide health benefits and that specific strains are safe for human use.

In a clinical trial of 19 patients, 44 single-rooted teeth will be randomly assigned to one of four groups for: 1) no treatment, 2) manual root planing with curettes; 3) root planing with piezoelectric ultrasonic scraper [PU]; or 4) root planing with vertically oscillating ultrasonic device [VOU]. Post-treatment, the teeth will be extracted and their topography analyzed in 124 observations with white light confocal microscopy, measuring the roughness parameters Rp, Rv, Rt, Ra, Rq, Rku, and Rsk.

The relationship between diabetes mellitus (DM) and periodontal disease is bidirectional. DM is a predisposing and modifying factor of periodontitis, which, in turn, worsens glycemic control and increases proteins found in the acute phase of inflammation. The gold standard for the treatment of periodontal disease is oral hygiene orientation, scaling and planing. Moreover, systemic antibiotic therapy may be employed in some cases. In an effort to minimize the prescription of antibiotics, photodynamic therapy (PDT) has been studied as an antimicrobial technique and has demonstrated promising results. The aim of the proposed study is to determine whether PDT as a complement to periodontal therapy (PT) is helpful in the metabolic control of individuals with type 2 diabetes and the reduction of acute phase inflammatory markers. The patients will be randomized using a proper software program into two groups: 1) PT + placebo PDT or 2) PT + active PDT. All patients will first be examined by a specialist, followed by PT performed by two other healthcare professionals. At the end of each session, PDT (active or sham) will be administered by a fourth healthcare professional. The following will be the PDT parameters: diode laser (660 nm); power output = 110 mW; exposure time = 90 seconds per point (9 J/point); and energy density = 22 J/cm2. The photosensitizer will be methylene blue (50 µg/mL). The patients will be re-evaluated 15, 30, 90 and 180 days after treatment. Serological exams with complete blood count, fasting glucose, glycated hemoglobin and crevicular fluid exams to screen for tumor necrosis factor alpha, interleukin 1, interleukin 6, osteocalcin, osteoprotegerin/RANKL will be performed at each evaluation. At baseline and 180 day periapical radiographs will be performed to evaluate the alveolar bone crest level. The data will be statistically evaluated using the most appropriate tests.

Periodontal disease is a major cause of tooth loss in humans and is one of the most prevalent diseases associated with bone loss. Following bacterial colonization, the gingiva becomes inflamed leading, in some cases, to the destruction of the alveolar bone. Periodontitis has two distinct but interconnected etiologic components, periodontopathic bacteria and host-mediated connective tissue-destructive responses to the causative bacteria and their metabolic products. A few studies have revealed that probiotic Lactobacillus strains were useful in reducing gingival inflammation and the number of black-pigmented rods, including Porphyromonas gingivalis (Pg), in the saliva and sub-gingival plaque. Concerning periodontal conditions, its shown that application of beneficial bacteria, as an adjunct to scaling and root planing (SRP), can inhibit re-colonization of pathogens in periodontal pockets and reduce bleeding on probing. The aim of the present study is to evaluate the improvement of periodontal health with probiotic (Inersan) lozenges, used as an adjunct to scaling and root planing [SRP].

The investigators wish to assess whether intensive periodontal therapy will reduce the burden of chronic periodontal disease and will cause regression or prevent progression of atherosclerosis assessed by a surrogate end-point (carotid intima-media thickness) at 24 months compared to control periodontal therapy.

In this clinical study, it was aimed to evaluate whether there is a decrease in patient anxiety by applying virtual reality glasses, which are the product of new technology, during scaling and root planing treatment. Patients who required scaling and root planing treatment and also scored 9 or above according to the Dental Anxiety Scale were included in our study. Scaling and root planing was performed in a randomly selected intraoral quadrant of the patients, in the same way, with or without the use of virtual reality glasses. In the virtual reality glasses application, a video consisting of images of nature landscapes developed for patient rehabilitation was projected onto the screen in front of the patient's eyes. The Dental Anxiety Scale was reapplied after the completion of the treatment. In the intraoral quadrant where virtual reality glasses were used, it is expected that lower Corah Dental Anxiety Scale scores may be obtained after the treatment is completed, compared to the intraoral quadrant where the treatment is performed without glasses, thus reducing anxiety.

the aim of our study is to enhance the dissolution and subsequently the local penetration of the drug through the sulcus in addition to controlling the drug release so that, the drug could be potentially absorbed.
