Filter by:SUMMARY Chronic periodontitis is regarded as an inflammatory disease that affects the supporting tissues of teeth which could lead to bone destruction. According to the pattern of bone destruction, vertical infrabony defect could occur. Several biomaterials have been used to treat infrabony defects including bone grafts, membranes, anti-microbials, growth factor & Enamel matrix proteins. CHX gel which has been widely used in the treatment of infra-bony defects. Chemical treatment of root surfaces of teeth have been used as an adjunct with mechanical instrumentation. Among these chemical agents is EDTA which was found to be able to remove the smear layer and expose the collagen fibers on the root surface which would make the root surface biocompatible favoring fibroblast attachment and increase substantivity of CHX gel. However, studies have found that there was no clinical significance of EDTA with chlorhexidine gel . Recent studies revealed that significant improvements could be obtained for deep intrabony defects after EDTA root surface etching and CHX gel application after non-surgical therapy compared to control non etched treated sites. This could be attributed to the associated prolonged and higher values of CHX levels for the CHX-EDTA-treated group. However, the main target of that work is to quantify levels of CHX during the early stages of healing to determine if such clinical improvement could be attributed to prolonged and increased CHX levels after EDTA root surface preconditioning. The aim of this study was to evaluate clinically the use of Chlorhexidine gel following root surface EDTA after open flap debridement in treating Intra-bony defects and to study the effect of EDTA bone etching on Bone Morphogenetic Protein-2 (BMP-2) in gingival crevicular fluid.
The aim of the present investigation will be evaluated the healing of suprabony defects following surgical flap elevation and hyaluronic acid application respect to surgical flap elevation alone. A total of 80 patients will be enrolled, selected by inclusion and exclusion criteria and randomly divided in two groups: hyaluronic acid group and no-hyaluronic acid group.

AIM AND OBJECTIVES: AIM To determine the association between periodontal bone loss and maxillary sinus changes through cone beam computed tomography. OBJECTIVES Primary objectives- 1. To compare the presence of maxillary sinus changes in patients with radiographic evidence of periodontal bone loss with healthy controls. Secondary objectives- 1. To determine the correlation between severity of periodontal bone loss with the changes in maxillary sinus. 2. To compare the mean maxillary sinus mucosal thickening in patients with radiographic evidence of periodontal disease with healthy controls. MATERIALS AND METHODOLOGY: STUDY DESIGN A retrospective study will be conducted in the department of Oral Medicine and Radiology, Post Graduate Institute of Dental Sciences, Rohtak. STUDY SETTING Hospital based study - CBCT volumes which are available in the archives of Oral Medicine and Radiology department will be evaluated. STUDY PERIOD This study will be completed in 6 months. STUDY SUBJECTS CBCT volumes of patients who have undergone CBCT examination between May 2019 and December 2020 for various dental purposes will be evaluated and the volumes fulfilling the inclusion criteria will be included in the study. The subjects will be divided into 2 groups- Periodontal disease group and Healthy group, INCLUSION CRITERIA 1. Good quality images with visualization of maxillary sinus and maxillary posterior teeth of at least one side. EXCLUSION CRITERIA 1. Signs of endodontic pathology like periapical radiolucency, root canal fillings etc. 2. Presence of metal artifacts interfering with the view of the maxilla. 3. Presence of trauma or pathologies such as tumours, cysts or malignancies that obscure the view of the region of interest. SAMPLE SIZE A minimum sample size of 71 maxillary scans in each group has been calculated to expect a difference of 26.84% in the prevalence of the 2 groups as ascertained from a pilot study, at a significance level of 0.05 and a power of 90%. Since group one will further be divided into 3 classes, a sample size of 225 in each group shall be taken. METHODOLOGY - CBCT volumes of patients who have undergone CBCT for various dental purposes between May 2019 to December 2020 available in the archives of Department of Oral medicine and radiology will be evaluated. - These scans will be screened for radiographic evidence of periodontal disease i.e. horizontal or vertical bone loss and bone loss at the furcation. - Further, the periodontal bone loss scans i.e. 225 will be divided into 3 groups of 75 each: mild (<25%), moderate (25-50%) and severe (>50%) according to the amount of bone loss. - The group with no bone loss will be taken as the control group i.e. 225. - Maxillary sinuses will be evaluated according to the following criteria; score range from 0 to 6 ; 0 - no mucosal changes.,1 - area without cortical bone and with soft tissue density, thickness >3 mm, parallel to sinus bone wall,2- sinus polyp, 3-antral pseudo cyst, 4- non-specific opacification,5- periostitis,6- antrolith. DATA MANAGEMENT AND STATISTICAL ANALYSIS Data will be tabulated in Microsoft Excel sheet. The results will be expressed as the frequency (%) of maxillary and Mean + Standard deviation (SD) for maxillary sinus mucosal thickening. Normality of data will be assessed and Chi-square or student T test shall be used for non-parametric and parametric data respectively. All analysis will be performed by SPSS software version 21. A p value less than 0.05 will be considered significant for all outcomes.
The aim of this study is to evaluate the accuracy of pulp test in teeth presenting with deep periodontal pocket. The null hypothesis is no significant effect of periodontitis on the accuracy of pulp test.
The aim of this study is to compare the effectiveness in periodontal regeneration of cross-linked hyaluronic acid at 1.8% (Hyadent BG®) with enamel matrix derivative (Emdogain®) in periodontal bone defects evaluating their clinical and radiographic variables.
The substitution of a tooth with a fixture often induces undesired morphological changes, resulting in a deterioration of the aesthetic appearance. The purpose of this study is to compare the soft tissue behavior next to two different implant connections: 5° (group 1) and 35° hexed (group 2), conical, internal with switching platform design after 12 months of functional provisionalization
Currently, the most positive documented outcomes of periodontal regenerative therapy (PRT) in intrabony defects (IBDs) have been achieved with a combination of bone grafts ( BGs) and a regeneration material like membranes in guided tissue regeneration ( GTR) technique. Among the graft materials only autogenous bone grafts ( ABGs).and demineralized freeze-dried bone allografts (DFDBA), are considered regenerative materials. Polypeptide growth factors revealed a potential application in PRT periodontal because are the biological mediators during wound healing and regeneration and autologous platelet concentrates ( PC) constitute a safe and convenient approach to deliver them. Among PC, platelet-rich fibrin ( PRF) belongs to a group of second-generation blood autologous products prepared by peripheral blood centrifugation without any nonclotting agent, so to obtain a dense three-dimensional clot architecture that concentrates platelets, fibrin, leukocytes, cytokines, and sustain cellular migration. This clot is then compressed to obtain elastic and very strong membranes that can be used directly as membranes or as an agent, after chopping, alone or in combination with BGs. Several studies demonstrate that PRF is effective in promoting bone regeneration (BR) when used alone or in combination with BG during oral/ periodontal surgery. To date, there are very few published clinical controlled trials that compare the results of PRF + BGs to the outcomes of PRF / BG alone in the treatment of IBDs and no study about PRF + ABG in the same defects. Only one case report tested the use of PRF + ABG mixed with bovine hydroxyapatite in the treatment of insufficient alveolar ridge width in aesthetic area. The aim of the present study is to verify if the combined use of PRF + ABG in the management of IBDs may be a treatment modality clinically "not inferior" to that with Membrane + ABG.
The present study pretends to show the results of combining a modification of the Non-incised papillae surgical approach (NIPSA) attempting to improve the outcome in the treatment of teeth with advanced periodontal support loss.
The evaluation of the clinical data has demonstrated the conformity of the Resorbable Collagen Membrane (RCM), EZ CureTM, with the relevant essential requirements for its use in periodontal applications. The RCM is intended for Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR) procedures. It acts as a barrier against the migration of epithelial cells within the bone defect (performance) and thus complies with several surgical indications in the treatment of maxillofacial bone defects. It has been concluded that the risks associated with the use of this device are acceptable when weighted against the benefits to the patients. In order to improve the clinical data on the RCM, the manufacturer, Biomatlante, decided to assess that the performance and safety of the device are maintained until the reaching of its intended use. In this objective, the goal of this study will be to observe the following parameters: 1. Tissue regeneration (mucosa health on the site of implantation) 2. Safety (report of any adverse event) 3. Radiographic analysis of periodontal tissues
