Filter by:Generalized aggressive Periodontitis (GAgP) and chronic periodontitis (CP) are inflammatory diseases. Little is known about molecular changes and signaling cascade of host response. Inflammatory diseases are undercontrol of genetic and enviromental factors. Transcription factors are gene-specific factors that are often considered to act as a link connecting genetic and enviromental factors. The aim of this study is to investigate the gene regions that are thought to play a role in the pathogenesis of GAgP and CP, and to interpret new and reliable pathognomonic-prognostic markers in the diagnosis and treatment of these diseases with the help of expression and mutation analyzes and polymorphism studies.
Objective: The present study aimed to determine the expressions of nuclear receptors PPAR (Peroxisome proliferative activator receptor)-γ, RXR (Retinoid X receptor)-α, and vitamin D receptor (VDR) in healthy volunteers and periodontitis patients with different grade involvement. Methods: Group-1; healthy individuals, Group-2; periodontitis patients-stage 3 grade B, (H-GradeB), Group-3; periodontitis patients-stage 3 grade C, (D-GradeC). Clinical parameters as plaque index (PI), gingival index (GI) and clinical attachment levels (CAL) were measured. Fibroblast and inflammatory cells, PPAR-γ, RXR-α, and VDR levels were determined in histological slides.
To evaluate the effect of systemic administration of zinc on the gingival crevicular fluid level of total oxidant capacity in controlled Type-2 diabetic patients with stage-II and III periodontitis after non-surgical periodontal therapy.
Observational cross-sectional study
The aim of this study is to evaluate the influence of periodontal care response on long term dental implant success. Investigator's hypothesis is that patients who do not well respond to periodontal care have more chance to develop peri-implant complications at long-term. The second purpose of this study is to evaluate the influence of other local, systemic, behavioral, and implant's related risk factors
this study is to evaluate the use of advanced platelet rich fibrin (A-PRF) + nano-crystalline hydroxyapatite bone substitute combined with open flap debridement (OPD) versus open flap debridement alone in the management of mandibular molar grade II defects. In the management of mandibular molar grade II furcation defects, no difference exists in gain of horizontal clinical attachment level between the use of advanced platelet rich fibrin (A-PRF) + with nano-crystalline hydroxyapatite bone substitute combined with open flap debridement (OPD) and open flap debridement (OPD) alone .
The study is a split mouth study but the interventions for the two different arms will be spaced by a fixed duration in time. Verbal and written consent will be obtained from the patients fulfilling the inclusion and exclusion criteria after briefing them about the procedure. Following phase-1 periodontal therapy, randomisation for the test and control quadrants will be done. Surgical debridement will be done first for the control side to avoid the carry-across effect of fibrin glue. Control and test procedures will be performed with a wash out period of 15days. Preparation of Autologous fibrin glue : - 10 ml of blood will be withdrawn from healthy adult human donor by venous puncture into sodium citrate vials and will be centrifuged for 30 min at 1200 g to obtain platelet-poor plasma (PPP). - To the solution, fibrinogen and protamine sulphate will be added and will be centrifuged at 1000 g for 5 min to sediment the precipitate and fibrin glue will be procured. Prior to commencement of periodontal flap surgery GCF collection will be done. Following anaesthesia and elevation of full thickness muco periosteal flap, thorough debridement and root planning of the exposed root surfaces will be done. On the control site, the periodontal flap will be approximated using 4-0 black silk suture. Patients will be instructed to rinse twice daily with 0.12% chlorhexidine and recalled after 7 days for suture removal and post-surgical GCF collection from the control side. After a wash out period of 15 days presurgical GCF sampling along with the surgical procedure will be performed on the test side. The periodontal flap will be approximated on the test site using autologous fibrin glue on the under surface of the raised flap up to 2 mm from the coronal margin and repositioned back on to the root surface. Thereafter, the tissues will be kept in position with a gentle pressure using a wet gauze for 30 - 60 seconds. Persistence of bleeding, stability of tissues 5 minutes after repositioning will be recorded and the amount of fibrin sealant used in the procedure will be determined.Patients will be then recalled after 7 days for evaluation and post-surgical GCF collection from the test site. Clinical parameters will be assessed at 7, 14, 21 and 28 days. Collection of GCF : GCF will be collected immediately prior to surgery and on seventh day following surgery from both test and control sites for wound healing assessment. Samples of GCF will be collected from four sites from the surgical site following isolation. Colour - coded, 1-5 microlitre calibrated volumetric micro capillary pipettes will be kept extra-crevicularly for not more than five minutes or until 1 microlitre is collected. The fluid will be immediately transferred to a plastic vial and frozen at -20 degree Celsius for further analysis. Pipettes in sites which do not express any fluid or those contaminated with blood/saliva will be discarded. Statistical analysis: The data gathered from the study will be subjected to appropriate statistical analysis. The statistical analysis will be done using: 1. Mann-Whitney test 2. Wilcoxon signed rank test.
AIM: To evaluate the association of the levels of blood haemoglobin to the distribution and severity of gingival melanin pigmentation at 3 different periodontal health status SAMPLE SIZE ESTIMATION - Done using GPower v.3.1.9.2 - Total sample size = 60 (20 each in 3 groups) - Effect size = 40% - Power = 80% - α-error = 5% SAMPLING: - Simple random sampling - Subjects to be recruited from out patient pool of KLE Society's Institute of Dental Sciences, Bangalore - Subjects to be categorised into 3 groups (20 subjects each) 1. Group A - Healthy periodontium 2. Group B - Gingivitis 3. Group C - Periodontitis PARAMETERS ASSESSED - Blood Haemoglobin Concentration (in %gm/dL) - Hedin Melanin Index Score 0: No pigmentation Score 1: one or two solitary unit(s) of pigmentation in papillary gingiva without formation of a continuous ribbon between solitary units Score 2: More than three units of pigmentation in papillary gingiva without the formation of a continuous ribbons of pigmentation Score 3: One or more short continuous ribbons of pigmentation Score 4: One continuous ribbon including the entire area between canines STATISTICAL ANALYSIS - SPSS for Windows Version 22.0 to be used - Descriptive statistics: It includes expression of study parameters in terms of Mean & SD for continuous variables, whereas in terms of frequency and proportions for categorical variables. - Inferential Statistics: Chi Square Test will be used to compare the pigmentation index between 03 groups. And similarly, gender wise comparison of hemoglobin concentration will be done using the same test. One-way ANOVA test followed by Tukey's HSD post hoc Analysis will be used to compare the mean hemoglobin levels based on the pigmentation index scores in each group. The level of significance [P-Value] was set at P<0.05
The present study aims to evaluate photodynamic therapy (PDT) using Zinc oxide as a photosensitizer as an adjunct to scaling and root planing (SRP) in the management of chronic periodontitis.
A randomized controlled triple blinded study to evaluate the effectiveness of Salvadora Persic (SP) as an adjunct to Scaling and Root Planing (SRP) in chronic periodontitis by comparing the basic parameters of periodontitis, radiographs and bacterial levels with a controlled group (SRP only).
