Active clinical trials for "Periodontitis"

Papillae tunneling techniques (PTT) are a new approach toward regeneration of isolated intrabony defects. Compared to regular papillae preservation techniques, PTT rely on complete preservation of involved interdental papillae, providing optimal healing environment for periodontal wound. Surgical access is therefore gained either by vertical incision in vestibulum, or by short releasing incision on adjacent tooth. Interdental tissue is then carefully raised in a full thickness manner by tunneling instruments, root surface thoroughly cleaned by the ultrasound scaler or Gracey curettes and defect filled with the biomaterial of choice. While the success and aesthetic results of non-incised papillae techniques are well documented, no paper so far compared clinical results of papillae preservation techniques with different biomaterials. Therefore, the aim of our study is to compare gain of clinical attachment level (defined by sum of pocket probing depth and recession) to regular papillae preservation techniques, and to prove non-inferiority of Gel 40® (collagen matrix, loaded with micronized heterologous bone) to Gen-Os® (granulated cortico-cancellous heterologous bone mix). Secondary objectives include analysis of aesthetic parameters - differences in recession and tip of the papillae location before and after the treatment.

Using local delivery drugs as adjunctive to scaling and root planing and evaluating gingival crevicular fluid (GCF) biological molecular markers (MMP-8).

Treatment of chronic medium-severe periodontitis with mesenchymal stem cells and mesenchymal stem cells predifferentiated in osteogenic direction

The study included 70 systemically healthy individuals, as a test group of 35 patients with Stage 3, Grade A periodontitis and a control group of 35 individuals with no periodontal disease. Blood samples were taken for the examination of DNI, white blood cells (WBC), immature granulocytes (IG), procalcitonin, C-reactive protein (CRP), lymphocyte count and neutrophil count. For the patients with periodontitis, blood sample assays were repeated 3 months after NSPT.

Regenerative endodontic procedures have been used to successfully treat human mature permanent teeth with necrotic pulps and apical periodontitis. Many researchers have begun to apply regenerative endodontic procedures to mature teeth in adult patients. Several clinical case reports have shown complete resolution of signs and symptoms of pulp necrosis in mature teeth, even those with large periapical lesions, as well as signs of pulp canal obliteration. The aim of this study is to assess the regenerative potential of mature permanent teethwith necrotic pulps after disinfecting the root canal using diode laser andcompare it with dynamic agitation of xp-endo finisher and conventionaltriple antibiotic paste

RESEARCH QUESTION: Will there be a difference in periodontal health of two groups of periodontally compromised orthodontic patients with early and delayed start of orthodontic treatment after periodontal surgery? Population: Adult orthodontic patients with periodontally compromised dentition requiring periodontal surgical management Intervention: Fixed orthodontic treatment started 10 days after periodontal surgery Control group: Fixed orthodontic treatment started 3 months after periodontal surgery Outcomes: changes in osseous (Alveolar bone level) and non-osseous (PI, GI, BOP, PD, CAL) periodontal parameters of the teeth involved in periodontal surgery. Time frame: One year and four months Study Design: Prospective, randomized controlled clinical trial. Specific: Yes Measurable: Yes Achievable: Yes Relevant: Yes Time: One year and four months Feasible: Trained staff, infrastructure, time, study design Interesting: A new treatment protocol will be investigated. Novel: No study comparing these waiting time intervals after periodontal surgery before starting orthodontic treatment. Ethical: Yes Relevant: As there is no clarity on waiting period after periodontally surgery in periodontally compromised adult patients, this study will be of great help in establishing treatment management protocol of such patients.

Healing rate after single visit or multiple visit endodontic treatment using triple paste intracanal medicament will be assessed both clinically and radio-graphically for follow-up period up to one year

Aim: The aim of this study was to evaluate the relationship between initial probing depth (IPD) and changes in clinical parameters following non-surgical periodontal treatment (NPT) in chronic periodontitis patients. Material and Methods: A total of 1672 periodontal pockets having 3 mm≤IPD≤9 mm in 15 chronic periodontitis patients were included. NPT consisting of oral hygiene instructions, scaling and root planing was applied in two sessions. Probing depth (PD), clinical attachment level, gingival recession (GR) were measured before and eight weeks after treatment. Pocket sites were grouped according to their IPD and root number of teeth as single- or multi-rooted.

The aim of this in vivo study is to evaluate the influence of apical periodontitis (AP) on the accuracy of Dentaport ZX, Raypex 5, and i-Root electronic root canal length measurement devices.

Aim of the present study is evaluate the use of erythritol powder with/without the adjunct of local metronidazole in the treatment of periodontal pockets. 20 consecutive adult periodontal patients, requiring cause-related therapy as phase 1 of their treatment plan, and presenting ≥4 sites with probing pocket depth ≥4mm will be enrolled. For each patients four sites will be considered for the study, and two sites will be allocated in the test group and two sites will be allocated in the control group. In the test group, ultrasonic debridement of the pocket will be performed using a piezoceramic ultrasonic device with the a tip connected to the handpiece for 5 minutes/pocket. Then, it will be followed by the subgingival use of erythritol powder 2x5 seconds/pocket. At this time the subgingival delivery of metronidazole gel will be provided. In the control group, the same protocol will be used except for the use of a placebo instead of metronidazole. After instrumentation, patients will rinse with chlorhexidine 0.20% 3 times/day for 2 weeks. At baseline, 1 month, 3 months and 6 months the following parameters will be evaluated: Probing Pocket depth (PPD), Bleeding on Probing (BoP), Clinical Attachment Level (CAL).
