Active clinical trials for "Periodontitis"

Clinical evaluation of local subgingival application of injectable platelet-rich fibrin ( i-PRF ) for chronic periodntitis as adjunctive to non surgical therapy and compare it with hyaluronic acid. 120 periodontal patients will receive a scaling and root planing ( non surgical periodontal therapy). Equal number of patients will receive subgingival application of i-PRF, hyaluronic acid or placebo gel as the adjunction to non surgical therapy.

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).

The study was designed to assess the effectiveness of conservation ridge preservation (horizontal and vertical dimension) after tooth extraction with and without combination of bone substitutes based on synthetic (calcium sulfate mixed with phosphate.

The study is designed to test the hypothesis that there is a difference in healing kinetics and healing rate between teeth treated by conventional endodontic procedure alone and those in which such procedure was supplemented with the Apexum Ablator protocol

This study is to determine whether scaling and root planing (SRP) followed by photodynamic disinfection results in improved outcomes that persist over time in adults with chronic periodontitis when compared with subjects with SRP alone.

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.

The aim of this study is to determine the efficacy of application of Lactobacillus Reuteri probiotics therapy on clinical improvement and on microbial shift in Chinese periodontitis patients.

Endodontic post-treatment pain management is one of the most challenging problems in the clinical practice of endodontics. Although this pain is decreased after root canal treatment, there may be residual symptoms due to inflammation. It has been reported that up to 80% of patients with preoperative pain, will report pain after endodontic treatment, which might range from mild to severe. Management of endodontic pain should involve all steps of treatment including preoperative pain control through accurate diagnosis and reduction of anxiety, intraoperative pain control through effective and profound local anesthetic, operative techniques and that can be achieved through a variety of pharmacologic agents. Many mechanisms have been proposed to explain the reason for postoperative pain including the sensitization of nociceptors by inflammatory mediators. Among these chemical inflammatory mediators are the prostaglandins which is the terminal product of arachidonic acid metabolism, through the cyclooxygenase (COX) pathway. Endodontic treatment can cause the release of inflammatory mediators (e.g. prostaglandins, leukotrienes, bradykinin, platelet- activating factor and substance P) into the surrounding periapical tissues, causing pain fibers to be directly stimulated (by bradykinin for instance) or sensitized (by prostaglandins). In addition, the vascular dilation and increased permeability as a consequence of periradicular inflammation, cause edema and increased interstitial tissue response. Single-visit root canal treatment is common in some endodontic practices. However, one of the main concerns with this approach has been the fear of post- operative pain. Mechanical, chemical and microbiological injuries to the peri- radicular tissues during root canal treatment have been suggested as possible causes of post-operative pain. The role of irrigating solutions used during root canal treatment to help control post-operative pain is unclear. While certain studies have observed a reduction in post-operative pain with particular types and concentrations of irrigating solutions, other studies have reported no difference in post-operative pain with the different irrigating solutions .

The presence of periodontitis has been hypothesized as a risk factor for several systemic outcomes, including chronic kidney disease (CKD). Therefore, the aim of this study is to evaluate the impact of non-surgical periodontal treatment on CRP levels and quality of life of patients with chronic kidney disease undergoing hemodialysis (HD) in Santa Maria-RS.
