Filter by:the aim of the study is to evaluate the efficacy of guided biofilm therapy (GBT) for treatment of deep periodontal pockets. the objectives are 1- To compare the change in the clinical periodontal parameters and microbiological parameters by using real time PCR for P. gingivalis, Aggregatibacter actinomycetemcomitans and Filifactor alocis among sites treated by GBT and conventional hand instrumentation after a period of 3 months and to assess the level of the selected periodontal pathogens in deep periodontal pockets and to estimate and compare deep periodontal pockets which need surgery after 3 months of non-surgical treatment by GBT and conventional hand instrumentation. the hypothesis is whether there are no differences in in the clinical and microbiological parameters among sites treated by GBT and conventional hand instrumentation after a period of 3 months or there are differences in in the clinical and microbiological parameters among sites treated by GBT and conventional hand instrumentation after a period of 3 months. The participants will be selected on a consecutive basis from patients referred to the Department of Periodontics, College of Dentistry, University of Baghdad. For each patient, each site will be randomly assigned to either treatment protocol: 1. Sites treated with GBT. 2. Sites treated with conventional manual instrumentation only.
The goal of this pilot study is to describe the early wound healing molecular events and the vascularization pattern associated with the treatment of supra-bony defects with access flap alone or in association with a combined formulation of hyaluronic acid and polydeoxyribonucleotides gel.
The current study is a prospective randomised split mouth study to evaluate the effect of Silk fibroin as drug delivery system while simultaneously assessing the efficacy of silk fibroin in comparison to chlorhexidine.
Platelet rich fibrin (PRF) has been widely used in regenerative dentistry since it provides plenty amount of growth factors that enhance wound healing and tissue regeneration. Platelet derived growth factor-BB (PDGF-BB) is a growth factor with essential functions such as regulation of cell migration, proliferation, and differentiation. This study aims to evaluate the efficacy of PRF in improving the clinical periodontal parameters and GCF level of PDGF-BB.
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.
Assessment of the efficacy of BMG0703 in the treatment of periodontitis and control of supragingival plaque, compared to Chlorhexidine and a placebo product
A coronectomy is often chosen over complete extraction of a lower third molar when the tooth appears to be in close proximity to the inferior dental (ID) canal, as assessed on a plain radiograph or a cone beam computer tomograph (CBCT). Following a coronectomy, the roots of the third molar may migrate in a coronal direction. This effect, along with the bone-preserving technique of a coronectomy over extraction, may provide increased bone height distal to the lower second molars, when compared to extraction. Partially erupted lower third molars, specifically those with mesio-angular impactions, are commonly associated with reduced bone height distal to lower second molars, and cause damage to the periodontal support of these neighboring teeth. It is assumed that maintenance of the impacted third molars or extraction of these teeth may compromise the periodontal status of the lower second molars. This study will investigate if coronectomy improves the bone levels, and therefore the periodontal status, of lower second molars, and may propose an indication for a coronectomy regardless of the proximity of the tooth to the ID canal. Coronectomies were first proposed as a treatment option just over thirty years ago, but there are very few long-term studies on the procedure reported in the literature. To the best of the investigator's knowledge, this will be the first randomised controlled trial comparing the bone height distal to the lower second molar following a coronectomy or extraction of the lower third molar.
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.
