INTRODUCTION The purpose of this study was to evaluate the antimicrobial efficacy of Triphala, green tea polyphenols (GTP), MTAD, and 5% sodium hypochlorite against E. faecalis biofilm formed on tooth substrate. METHODS Extracted human teeth were biomechanically prepared, vertically sectioned, placed in the tissue culture wells exposing the root canal(More)
INTRODUCTION The Enterococcus faecalis biofilm in the root canal makes it difficult to be eradicated by the conventional irrigants with no toxicity to the tissues. Hence, plant products with least side effects are explored for their use as irrigants in the root canal therapy. AIM To evaluate and compare the antibacterial efficacy of Mangifera indica L.(More)
A questionnaire based study conducted to identify the awareness and applications of cloud computing in libraries in Indian context. It is found that most of the respondents (98.2%) are aware of the term cloud computing and 87.7% of the respondents are aware of the application of cloud computing in libraries. Half of the respondents (52.6%) are of the(More)
Three antibody assays (anti-PGL-1, anti-35 kDa and anti-LAM) were used to determine the levels of antibodies in the sera of untreated leprosy patients. All the three assays showed higher levels of antibodies in BL/LL patients as compared to I and TT/BT patients, as well as healthy controls. BL/LL patients showed positivity of 100%, 84.2% and 78.9% by(More)
INTRODUCTION The purpose of this study was to compare the bone thickness of the palatal areas in different palatal index (PI) groups. MATERIALS AND METHODS Cone-beam computed tomography scans of 10 subjects were selected with ameanage group of 18 years. The measurements of palatal bone thickness were made at 36 sites using CareStream 3D Imaging software.(More)
OBJECTIVE The aim of the present study was to evaluate the presence of Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) and Porphyromonas gingivalis (P. gingivalis) in subgingival plaque of healthy young children aged between 3 and 15 years using Polymerase Chain Reaction (PCR) and to compare their presence in children in their primary,(More)
OBJECTIVE The objective of the study was to evaluate the effectiveness of chitosan and chitosan-ethylenediamine tetraacetic acid (EDTA) (3:1,1:1,1:3) in comparison with 5.2% sodium hypochlorite (NaOCl) in disinfecting Enterococcus faecalis biofilm on root canal dentin and in the removal of smear layer with minimal erosion. MATERIALS AND METHODS Seventy(More)
A controlled-release device (CRD) containing chlorhexidine gluconate, such as PerioCol™CG (Eucare Pharmaceuticals Pvt. Ltd,, Chennai, India), for subgingival application has little reported data with clinical as well as antimicrobial efficacy. This study evaluated clinical and subgingival microbial changes on using indigenously developed PerioCol™CG as an(More)
OBJECTIVE This study was designed to evaluate the efficiency of microwave sterilization of orthodontic instruments and molar bands immersed in plain distilled water with and without oral rinse, and to ascertain the minimum time of exposure required to sterilize. MATERIALS AND METHODS The orthodontic instruments (hinged and nonhinged), molar bands and(More)
PURPOSE Enterococcus faecalis (E. faecalis) is implicated as the common etiological agent of root canal treatment failure. The study was aimed to compare the antibacterial efficacy and to assess the minimum inhibitory concentration (MIC) of 3 gutta-percha solvents-RC Solve, Endosolv-E, and xylene against E. faecalis. METHODS Agar well diffusion assay was(More)
