Active clinical trials for "Periodontitis"

The purpose of the present study was to evaluate the effects of subgingival delivery of boric acid gel as an adjunct to scaling and root planing in chronic periodontitis (CP) patients.

In this study, the researchers will investigate the effect of single-file reciprocating versus single-file rotational file systems on the postoperative pain in adult patients who have necrotic pulp and apical periodontitis. The participants will be assigned by chance to separate groups that compare 2 different treatments, reciprocating single-file system (Reciproc Blue) and rotational single-file system (OneShape). As a reference, Mtwo multi-file (full-sequence) will be used.

The aim of this study was to formulate a mucoadhesive gel of grapes seed extract (GSE) followed by short-term clinical study for the effectiveness of this gel onto the pocket depth (PD), plaque index (PI), gingival index (GI), and bleeding on probing (BOP) when applied in periodontal pockets as an adjunct treatment for chronic periodontitis.

The aim of study was to evaluate the effect of dental operating microscope use on the healing outcome of non surgical endodontic treatment of maxillary molars.

The main purpose of the study is to quantify of Leptin hormone in patients with normal weight, class I obesity, class II obesity and periodontitis, before and after scaling and root planning (SRP) and correlate the Body mass index (BMI) with Leptin levels. A double-blind, controlled, clinical trial was conducted. The sampling method was probabilistic stratified and the sample size 27 subjects in total, divided in 3 groups of: 9 normal weight patients, 9 class I Obesity patients and 9 class II Obesity patients and history of Generalized Periodontitis Stage II,III or IV, Grade B or C, who met the inclusion and exclusion criteria and signed an informed consent. All patients received SRP and clinical monitoring at baseline and 3 months post-therapy by the same examiner.Probing depth (PD), Clinical Attachment Level (CAL), Biofilm Index (BI) and Bleeding on Probing (BoP), Tooth Mobility and Suppuration were evaluated as clinical variables. Serum levels of leptin were evaluated by enzyme-linked immunosorbent assay (ELISA) at baseline and 3 months post SRP.

Aim: This study aims to assess the effect of root canal disinfection with a 980 µm diode laser following chemomechanical root canal preparation on the severity of pain after root canal treatment (RCT). Materials and Methods: In present study, asymptomatic, single-rooted teeth with periapical index (PAI) score 3 or 4 were included. All patients were treated with two visits of root canal treatment including dressing with calcium hydroxide. Patients were randomly divided into two groups (n: 28). 'Control (no laser)': The final irrigation was performed using 5ml 2.5% NaOCI, followed by 5 ml 17% EDTA and 5 ml distilled water. 'Laser Disinfection (LD)': Root canals were irradiated with 980 µm diode laser after final irrigation at both visits. The pain levels were evaluated using visual analog scale (VAS) after 8, 24, 48 hours and 7 days. In addition, analgesic intake and time intervals were recorded by patients. The collected data were statistically analyzed with the Chi-square and Mann-Whitney U test (p<0.05).

Background: To effectively disrupt microbial biofilm and remove dental calculus with minimal damage to the root surface and soft tissues with limited patient discomfort constitute a significant tenet of periodontal therapy. The aim of the present prospective 12-month study was to compare clinical and microbiological effects following an erythritol air-polishing vs. conventional mechanical debridement of furcation defects in a cohort of periodontal maintenance patients. Methods: Twenty patients with grade II mandibular molar furcation defects volunteered to enroll in this study. In a split-mouth design, two furcation sites in each patient were randomly assigned to either receive subgingival debridement using erythritol air-polishing (test) or conventional ultrasonic/curette debridement (control) at baseline, and at 3, 6, 9 and 12 months. Probing depth, clinical attachment level and bleeding on probing were recorded at 3-month intervals. Subgingival microbiological samples obtained at baseline, 6 and 12 months were analyzed using checkerboard DNA-DNA hybridization. Discomfort from treatment was scored at 12 months using a visual analogue scale.

Aim To evaluate the clinical and microbiological effects of a hyaluronan (HY) as adjunct to scaling and root planning of residual pockets during supportive periodontal therapy. Material and Methods Sixty-six chronic periodontitis, that have completed the active phase of treatment and are enrolled in a supportive periodontal therapy scheme, with 4 to 8 interproximal sites with PD ≥ 5 mm < 8 mm and presence of BoP at the revaluation examination will be randomly assigned to the test (HY containing gel) or control group. Immediately after debridement of the residual pockets the test gel (GUM® Afta Clear Gel, Sunstar) will be applied into the experimental sites by the operator. Further, the participants will be instructed to apply at the experimental sites the test gel supragingivally with an interdental brush (TePe, Malmö, Sweden), once per day after tooth brushing for the first 3 months. Subgingival gel application will be repeated at the 3-month control in persistent pockets (i.e. PD ≥ 5mm + BoP). CAL, PD, BoP, and presence of plaque will be evaluated at baseline and thereafter every 3 months (i.e., after 3, 6, 9, and 12 months). Further, subgingival microbiological samples will be collected from the 4 experimental sites at baseline, 3, 6, and 12 months. Nine periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia, Parvimonas micra, Campylobacter rectus, Eikenella corrodens), total bacterial load, and amount of Candida albicans will be determined quantitatively by real-time PCR.

The aim of the study is to evaluate in patients with history of periodontitis the clinical, microbiological and radiological outcomes of implants with a modified implant design consisting on a machined surface in the coronal third of the implant. In this 12-month, parallel-arm, randomized controlled trial, patients with history of treated periodontitis and in need of dental implants for single-unit or short edentulous spaces (i.e. two implants) will be randomly assigned to a test group (implants with a hybrid surface, presenting a machined coronal third; HS) or a control group (conventional moderately rough implants; RS). Implants will be restored 3 months later with fixed implant supported reconstructions. Radiological, clinical, microbiological and patient-related outcome measures (PROMs) will be assessed 3, 6 and 12 months after the prosthetic installation.

With poorly controlled diabetes, periodontal status often worsens, and with severe periodontal conditions there is often poorer glycemic control. There are few published reports investigating the efficacy of periodontal therapy in diabetics and fewer that include evaluation of the oral microbial profiles (the microbiome). The investigators will examine systemic changes in diabetes status and microbiome influences on clinical response to periodontal therapy in a randomized clinical trial of participants with and without diabetes and with periodontal disease. Two different treatments will be used: Scaling and root planning (SRP) alone, or SRP and supportive periodontal therapy (SPT), the use of chlorhexidine gluconate rinse (Paroex®) and a rubber interdental bristle cleaner (Soft-Picks) The main goal of this clinical trial is to evaluate the effects of SRP alone versus SRP+SPT on clinical, microbiological and immunological status in participants. A clearer understanding of how periodontal therapy affects diabetes status could lead to the development of new therapies for periodontal disease and diabetes.
