Filter by:Pathologic tooth migration (PTM) is a common complication of advanced periodontitis and often motivation for patients to seek orthodontic therapy. An interdisciplinary approach is required to control the periodontal infection, reconstruct the defects and realign the migrated teeth. The optimal timing of active orthodontics after regenerative therapy is a topic of ongoing debate. There are no data available from RCTs that have compared the effect of the timing of orthodontic tooth movement (early vs. late) on the outcomes of regenerative periodontal surgery in these patients. It is the aim of the present randomized clinical multicenter trial to compare 2 different treatment protocols of a combined perio-regenerative and orthodontic therapy in advanced periodontitis patients with intrabony defects and pathologic tooth migration in order to establish whether one treatment modality is superior to the other with regard to clinical outcomes. A total of 46 patients will be enrolled and randomized into 2 treatment groups that differ by the time point of initiation of orthodontic therapy (early: 4 weeks vs. late: 6 months following regenerative periodontal surgery). Primary outcome measure will be the change in clinical attachment level (CAL gain) at 12 months after regenerative therapy. Secondary outcomes will include changes in probing depth BOP, gingival recession, radiographic bone height and patient-centered outcomes.
200 patients took part in the questionnaire and were examined using the PSI. Thereafter the participants were divided into two groups, non-periodontitis persons (group 1; PSI 0-2) and periodontitis persons (group 2; PSI 3-4). The answers were evaluated using a point system ranging from 0 to 8, based on known periodontal risk factors and their assumed degree of influence. Receiver-operating characteristic (ROC) curve analyses were applied to examine the overall discriminatory power, sensitivity and specificity, and corresponding cut-off points of the self-reported periodontal disease scale.
The aim of this randomized clinical trial is to compare the antibacterial effects of 1% sodium hypochlorite (NaOCl) and 2% chlorhexidine gluconate (CHX) during retreatment of teeth with apical periodontitis (AP).
The aim of this study is to investigate the effects of non-surgical periodontal treatment on the metabolic control of type2 diabetes patients. Patients with type two diabetes mellitus patients and confirmed chronic periodontitis will be selected and randomly assign to two groups. The treatment group will receive immediate full-mouth scaling and root planing whereas the control group will be scheduled to receive periodontal treatment at the following 3-month visit. Plaque index, bleeding index, probing pocket depth, recessions and cervical attachment loss will be recorded at baseline, at six weeks and at three months. Glycated haemoglobin (HbA1c) and C-reactive protein (CRP) will be analysed at baseline and three months following enrolment.
The aim of this prospective interventional study is to verify the efficacy of smoking cessation on clinical and microbiological outcomes of non-surgical periodontal therapy of chronic periodontitis patients. Smokers willing to quit received periodontal treatment and concurrent smoking cessation therapy. Periodontal maintenance was performed every 3 months. A single calibrated examiner, blinded to smoking status, assessed periodontal clinical outcomes and applied a structured questionnaire in order to collect demographic and behavioural information. Further, expired carbon monoxide concentration were measured with a monoximeter. A pooled subgingival plaque sample was collected from the deepest periodontal pocket from each participant. The presence and quantification of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola were determined using (RT-PCR).
The purpose of this double-masked, randomized, controlled clinical trial was to evaluate the effects of subgingival delivery of boric acid gel as an adjunct to scaling and root planing (SRP) on clinical and radiographic parameters and compare this method with SRP plus placebo gel alone in patients with chronic periodontitis (CP).
The aim of this study was to compare the clinical and microbiological outcomes of different dosages of metronidazole (MTZ) and of the duration of the systemic administration of MTZ and amoxicillin as adjunct to scaling and root planing (SRP) in the treatment of generalized chronic periodontitis (GChP).
Chronic periodontitis (CP) is an infectious disease resulting in inflammation of the supporting structures of the teeth, progressive loss of bone loss and insertion. The aim of this study is to evaluate the effects of antimicrobial Photodynamic Therapy (aPDT) as adjuvant to periodontal surgery treatment (PST) in patients diagnosed with generalized severe chronic periodontitis (GSCP). Twenty patients with a clinical diagnosis of CP will be treated in a split-mouth design study to either aPDT associated with surgical access for scaling and root planning (SASRP) or SASRP only. aPDT will be performed by using a laser light source with 690 nm wavelength associated with a phenothiazine photosensitizer. The applications will occur in only one episodes. All patients will be monitored for 30 and 90 days after PST. Clinical assessment of plaque index, probing depth, clinical attachment level and bleeding on probing will be performed at baseline (pre-intervention period) and 30 and 90 days after the PST. Subgingival plaque samples will be collected (at baseline and 30 and 90 days after the PST) and the counts of 40 subgingival species will be determined using DNA-DNA checkerboard hybridization. Data obtained will be statistically analyzed.
Summary The aim of this study is to evaluate through clinical, microbiological and immunological parameters using PLGA microspheres (lactic-co-glycolic acid polyacid) containing doxycycline in periodontal therapy in smokers with chronic periodontitis. For this study, 40 patients will be selected, with an average age between 30 and 59 years old of both genders (male and female), who spontaneously seek the clinic graduate of the Piracicaba Dental School -FOP / UNICAMP, and exhibiting at least four bleeding sites, including 2 sites with a probing depth (PD) between 5 and 6 mm and two sites PS ≥7 mm in uniradiculares teeth. Patients should have a minimum of 20 teeth. Will be excluded from relevant systemic disease carriers or antibiotics used in the 6 months preceding the study. All patients will receive oral hygiene instruction and will undergo a pre-treatment, which will be held supragingival sweeps and removal of plaque retentive factors. Patients will be divided into 2 groups (DB + DOX: Debridement + Doxycycline, test group and DB: only debridement, control group) of 20 patients who will receive the following treatments: periodontal debridement ultrasound for 45 minutes associated with the local administration of 1 mg microspheres containing doxycycline, or just mechanical debridement, for each selected site. Will be assessed the following clinical parameters: gingival index (GI) Plaque Index (PI), Bleeding on Probing (BOP), Position of the gingival margin (PGM), Probing Depth (PD) and Relative Clinical Attachment Level (RCAL). The microbiological evaluation will be made by means of polymerase chain reaction - real time ( "real time" - PCR) to detect bacteria: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans and Prevotella intermedia. The enzyme immunoassay (LUMINEXMAGPIX) allow the detection of cytokine levels of GM-CSF, INF-γ, IL-10, IL-12, IL-13, IL-1β, IL-4, IL-6, IL-8 and TNF-α. The analysis of the proteolytic enzyme activity is accomplished by using zymography to assess MMP-8 and MMP-9. The described parameters will be evaluated at baseline, 45 and 90 days after the initial visit. The results are compared statistically by analysis of variance with repeated measures with 5% significance level.
The investigators primary objective in this clinical intervention study, therefore, was to explore the impact of omega-3 PUFAs in conjunction with scaling and root planing on salivary markers (in patients with chronic periodontitis.
