Clinical, radiological evaluation of the regenerative surgical method and the GBT non-surgical therapy in solitaire deep intrabony periodontal defect.
NCT07230522
The goal of this clinical trial is to learn whether hyaluronic acid (HyaDent® BG) provides similar benefits to Emdogain® when both are used with Bio-Oss® Collagen during periodontal surgery in adults with periodontal (intrabony) defects. The main questions it aims to answer are: Does the treatment reduce probing pocket depth? Does the treatment increase clinical attachment level? Does the treatment increase radiographic bone fill? Does the treatment change the gingival margin position? Researchers will compare Bio-Oss Collagen + HyaDent BG with Bio-Oss Collagen + Emdogain to see whether HyaDent BG achieves similar improvements in clinical and radiographic outcomes as Emdogain. Participants will: Undergo periodontal surgery to treat the vertical bone defect(s), with either Bio-Oss Collagen + HyaDent BG or Bio-Oss Collagen + Emdogain. Attend follow-up visits for periodontal measurements and radiographs.
NCT07119307
The present three-arm study compared the clinical and tomographic efficacy of the Entire Papilla Preservation Surgical Technique (EPPT) alone and combined with enamel matrix derivative (EMD) plus bone mineral derivedxenograph (BMDX), in the treatment of isolated, inter-dental intra-bony defects.
NCT07146776
The use of injectable platelet-rich fibrin (i-PRF) in both surgical and non-surgical dental treatments has become increasingly widespread. Hard tissue grafts can produce "sticky bone," and bone gain can have a positive effect on intrabony defects frequently seen in periodontal disease, compared to grafts alone. This study aims to clinically and radiographically evaluate the effectiveness of using bovine-derived xenogenic bone grafts in combination with i-PRF and bovine-derived xenogeneic bone grafts alone in patients with intrabony defects and stage III periodontitis.
NCT06633640
Periodontal diseases are one of the most prevalent chronic diseases involving a spectrum of inflammatory conditions. Intrabony defects, also known "vertical defects," are specific osseous and morphological defects and one of the consequences and end result of periodontitis. Intrabony defects are particularly associated with periodontal progression however certain patient-related factors play important role in its management such as plaque management, smoking, medical history, tooth mobility and endodontic condition. Periodontal repair is aimed to gain periodontal attachment using various modalities in severely compromised teeth, decrease pocket depth, and stabilize gingival recession. Different types of biomaterial substitutes and bone graft materials are available, but the choice of suitable "golden" type or technique is difficult and dependent on various factors particularly anatomical variations, cost effective, clinical situations, the systemic general condition, operation site, socioeconomic conditions and the surgeon choice. The current therapeutic options mainly focus on minimize symptoms and prevent disease progression but are not able to fully restore damaged bone and periodontal supporting tissues. Many of these regenerative approaches, (e.g. bone grafts) provided variable and unpredictable clinical outcomes. Therefore, it is imperative to develop alternative regenerative strategies. There is necessity to introduce novel and alternative materials of natural and synthetic origins for bone grafting use in dental field. This requires well performed clinical trials on humans to understand the effects of such materials (e.g the marine algae-based substitutes and biodegradable (absorbable) materials) either as a single or combined formula. The aim of the current clinical study is to evaluate the clinical efficacy of an algae-based biphasic bone graft material (AlgOss 20/80) and collagen membrane in the treatment of patient with intrabony periodontal defects.
NCT06347263
The goal of this Clinical trial is to evaluate the clinical and radiographic outcomes of using entire papilla preservation technique with and without autogenous bone and injectable platelet rich fibrin in treatment of isolated Intrabony defects in patients with stage III periodontitis.
NCT06041854
Periodontal intrabony defects represent a major challenge for the clinician in periodontal therapy. If left untreated, these defects represent a risk factor for disease progression and additional attachment and bone loss. All patients will receive full mouth scaling and root planing and be re-evaluated to assess patient cooperation and maintaining good oral hygiene. Subjects who showed persistent PPD ≥ 5 mm with radiographic evidence of periodontal intrabony defect presence will be included and will be randomly allocated to one of two treatment groups.One group will be treated by surgical treatment and the defects filled by freeze-dried bone allograft mixed with enamel matrix derivative. second group will be treated by surgical treatment and the defects filled by freeze-dried bone allograft .Clinical periodontal parameters (PI, GBI, PPD, CAL) will be re-evaluated at 3, 6 and 9 months after surgery. CBCT will be taken after 9 months of surgery and the defect measurements will be recorded
NCT06371027
Clinically and radiographically by cone beam CT evaluate the regenerative potentials of silk fibroin (SF) nanofiber membrane, using minimally invasive surgery, for the regenerative treatment of intrabony periodontal defects.
NCT05858411
The aim of the present study is to clinically and radiographically evaluate the efficacy of recombinant human platelet-derived growth factor (rhPDGF) in intrabony defects following scaling and root planing (SRP). This study will be designed as a randomized clinical trial of 12-month duration. A total of 51 patients (each with a single infrabony defect) will be recruited and randomly equally distributed into 3 groups: an experimental group treated with SRP and rhPDGF, a first control group treated with SRP and collagen sponge and a second control group treated with SRP alone. Each defect will be treated with an ultrasonic scaler with dedicated thin tips for supra- and subgingival debridement associated with hand instrumentation under local anesthesia. Caution will be taken to preserve the stability of soft tissues. Following SRP, experimental and control sites will be randomly chosen. The test sites will be treated by inserting a collagen plug soaked for at least 15 minutes in a 1.5cc solution containing hPDGF-BB. In the first control group the infrabony defects will be treated with SRP and a collagen sponge soaked in saline solution. In the second control sites no further treatment will be carried out. Pre- and post-treatment clinical measurements were performed by an examiner blinded to the treatment modalities using a graded periodontal probe (HuFriedy UNC 15). Before the treatment and at 6 and 12 months post-treatment, all patients were examined by measuring the clinical attachment level, probing depth, gingival recession, full-mouth plaque score and bleeding on probing. Standardized radiographs of selected study sites will be taken at baseline and at the 6 and 12 months follow-up visits using the long-cone technique with a customized holder and a thermoplastic occlusal reference to allow reproducible positioning. All radiographs will be analysed by a dedicated dental software (Carestream Dental LLC Atlanta, GA, USA) to make linear measurements. The defect bone level (DBL), the defect angle (DA) and the radiographic defect area (RDA) will be evaluated.
NCT04767243
The aim of this study is to evaluate and compare the regenerative potential of Advanced Platelet Rich Fibrin (A-PRF) and Bioactive Glass (Perioglas®) bone graft in the treatment of intrabony defects in chronic periodontitis patients.
NCT05354037
The use of Enamel Matrix Derivative (EMD) associated to microsurgical flaps was demonstrated to be effective for the treatment of intrabony defects, in particular in presence of a self-contained anatomy. The main aim of this study will be to evaluate the difference in Clinical Attachment Level (CAL) between baseline and 1-year follow-up, comparing flapless periodontal regeneration using EMD versus the use of EMD after microsurgical flap elevation (Modified-Minimally Invasive Surgical Technique (M-MIST) / Single-flap approach).
NCT03924336
To assess the effectiveness of advanced PRF+ as compared to open flap debridement in treatment of periodontal intraosseous defects in stage III periodontitis patients.
NCT04932161
The ideal goal of the periodontal treatment is not only to prevent the progression of the disease, but also the regeneration and reconstruction of lost tissues. Many surgical techniques have been used to regenerate intrabony defects (IBD). Titanium stimulates activation of the complement system, surface binding of platelets, and platelet activation as reflected by increased levels of platelet-derived growth factor, which is a substantial promoter of bone growth. Hence we may speculate that using a bone substitute made of titanium may be positive from the perspective of bone formation in osseous defects.
NCT04195295
The prospective study is a interventional study to evaluate and compare the effectiveness of periosteal pedicle as grafting technique and egg shell derived nano hydroxyapatite as regenerative graft material for regeneration of intrabony defects.
NCT04444063
Several minimal invasive techniques have been proposed since the last decade aiming to enhance and provide adequate environment for periodontal regeneration. Harrel and Rees proposed minimally invasive surgery (MIS) in 1995 and minimal invasive surgical technique (MIST) that was introduced in 2007 and then further enforced with modified minimally invasive surgical technique (M-MIST) in 2009 . A new minimal invasive technique called Non-Incised Papilla Surgical Approach (NIPSA) was introduced in 2017. It is aims to maintain the marginal tissues integrity by placing horizontal or oblique incision apical to the defect approaching the defect through apical access.
NCT03769402
This study evaluates the effect of citric acid on bone surface of infrabony defects when used for 30 seconds at ph 1 and 50% concentration before the application of bovine derived xenograft to fill the defect, Bone Morphogenic protein 2 (BMP-2) marker was evaluated in 5 different days during the first month after surgery and clinical and radiographic parameters were reassessed after 6 months
NCT03588507
This study is meant to assess clinically and radiographically the possible predictable results regarding the use of nanocrystalline hydroxyapatite bone graft substitute together with papilla preservation flap versus papilla preservation flap alone in the treatment of periodontal intrabony defects. Patients will be randomly assigned to either test or control group. The two groups will be equally prepared for both surgical procedures. Then the decision of which group will receive (PPF techniques + Nanocrystalline hydroxyapatite bone graft) and which will receive (PPF techniques only) will be taken.
NCT03009097
Periodontitis is a major oral health problem which leads to the progressive destruction of periodontal ligament and alveolar bone with pocket formation, recession or both. The ultimate goal of periodontal therapy is to regenerate the lost periodontal tissue. The most common form of regenerative periodontal therapy is the use of bone grafts which stimulate bone formation by the processes of osteoinduction and osteoconduction. Statins are a group of lipid lowering drugs which inhibit bone resorption by inhibition of the enzyme HMG-CoA reductase. They also stimulate new bone formation by local stimulation of BMP-2, a major bone growth regulatory factor. They also have anti-inflammatory and anti oxidant properties. Very few studies exist evaluating the beneficiary effects of grafts if combined with the statins which might enhance the regeneration by bone grafts. Hence, the present study was carried out in an attempt to comparatively evaluate clinically and radiologically, the efficacy of atorvastatin gel as an adjunct to allograft in the treatment of intrabony defects.
NCT02810054
After performing the power calculation, healthy adult participants for the study will be randomly allocated into two groups. The intervention group will receive minimally invasive surgical techniques (MIST) with enamel matrix derivative (Emdogain) as a treatment of intrabony periodontal defect. The control group will receive minimally invasive surgical techniques (MIST) without enamel matrix derivative (Emdogain). Clinical attachment level (CAL) gain and periodontal pocket depth (PPD) reduction as well as the position of gingival margin (REC) as the main outcomes and the radiographic intrabony infill, bleeding on probing (BoP), full mouth plaque score (FMPS) and full mouth bleeding score (FMBS) as secondary outcome will be recorded for the participants by 3 examiners at three stages: 1. Before the procedure as a baseline record. 2. 6 months after surgery, all parameters EXCEPT intra oral periapical (PA) radiographs. 3. 12 months after surgery. The readings will be recorded using The University of Michigan O Probe with William's Calibration OR Pressure Sensitive Periodontal Probe at 0.3 N to the nearest millimeter for the clinical attachment level gain (CAL), the periodontal pocket depth (PPD) and the position of gingival margin (REC), present or absent for the bleeding on probing (BoP), and intra oral periapical (PA) radiograph for crestal bone level assessment.
NCT02795546
