Evaluation of loop-mediated isothermal amplification method for efficient detection of the periodontopathic bacteria .

Background: Periodontitis is a multifactorial, polymicrobial oral inflammatory illness brought on by oral pathogens. is a Gram-negative, obligatory anaerobic, black-pigmented coccobacillus and is regarded as a primary etiological factor in the progression of periodontitis. Rapid, highly senstitive and specific detection methods are emerging.

Association of and with Periodontitis Disease Severity and Red Complex Bacteria.

Oral biofilms are considered the principal etiological agent in the development of periodontitis. Novel species that may contribute to periodontitis and dysbiosis have been identified recently. The study aims to evaluate the presence of and in healthy and diseased patients and their association with clinical parameters and with red complex bacteria.

Polymerase chain reaction-based identification of various serotypes of in adults with and without dental caries.

Background: Dental caries is a multistep process which initiates the development of plaque' defined as a structured biofilm containing microbial communities. Teeth provide unique surfaces for bacterial colonization. Serotypes of implicate the development of dental caries.

Simultaneous detection and evaluation of , and in subgingival plaque samples of chronic periodontitis and healthy individuals through multiplex polymerase chain reaction.

Background: is a Gram-negative anaerobic bacilli. The phenotypic characteristics of the various species of are similar, which often makes it difficult in routine differentiation and identification of all the species.

Aim: The purpose of the study was to detect and compare presence of , and in subgingival plaque samples of chronic periodontitis and healthy individuals.

Curcumin-Encapsulated Nanomicelles Improve Cellular Uptake and Cytotoxicity in Cisplatin-Resistant Human Oral Cancer Cells.

Oral cancer has a high mortality rate, which is mostly determined by the stage of the disease at the time of admission. Around half of all patients with oral cancer report with advanced illness. Hitherto, chemotherapy is preferred to treat oral cancer, but the emergence of resistance to anti-cancer drugs is likely to occur after a sequence of treatments.

Cancer Stem Cell Traits in Tumor Spheres Derived from Primary Laryngeal Carcinoma Cell Lines.

Objective: Cancer stem cells (CSCs) belong to a subpopulation of undifferentiated cells present within tumors that have the potential to regenerate, differentiate, maintenance of pluripotency, drug resistance, and tumorigenicity when transplanted into an innate host. These can influence the growth and behavior of these tumors and are used to investigate the initiation, progression, and treatment strategies of laryngeal cancer. Research on CSC science and targeted therapies were hinge on their isolation and/or enrichment procedures.

Individuals Age Determination from Human Dental Pulp Through DNA Analysis by PCR.

 Age estimation in forensic odontology is having a great importance in recent times because of the request by court or other government authorities so that immigrants whose real age is unknown should not suffer unfair disadvantages because of their supposed age, and so that all legal procedures to which an individual's age is relevant can be properly followed.  The present study was planned to be conducted on pulp tissue and dental hard tissues derived from individuals for DNA isolation and age determination .  The present study was an experimental single-blinded study consisting of 30 extracted teeth categorized into three groups as follows: Group A: 10 to 20 years, Group B: 21 to 30 years, Group C: 31 to 40 years.

Effect of curcumin on growth, biofilm formation and virulence factor gene expression of Porphyromonas gingivalis.

Porphyromonas gingivalis is a keystone pathogen and major colonizer in host tissue which plays a pivotal role in periodontitis among the other polymicrobial infections. Increasing facts demonstrate that curcumin has antibacterial activity and anti-biofilm effect against the periodontopathogens through diverse mechanisms that have a positive impact on periodontal health. The present study was aimed to elucidate the effect of curcumin on biofilm formation and virulence factor gene expression of P.

Detection and comparison of microsatellite marker D9S1747 with clinical stages and grades of oral squamous cell carcinoma.

Background: One of the main characteristics of oral squamous cell carcinoma (OSCC) is genetic alteration in specific target regions. Allelic imbalance in tumor suppressor genes is the key event in OSCC which is associated with loss of heterozygosity mostly on chromosome 9p21 locus which includes p16 marker. p16 (D9S1747) is a microsatellite marker which detects early changes in OSCC.

Effect of Resveratrol on biofilm formation and virulence factor gene expression of Porphyromonas gingivalis in periodontal disease.

Periodontal disease is an oral inflammatory disease that destroys the tooth supporting periodontal tissues resulting in tooth loss. Porphyromonas gingivalis is a keystone pathogen that plays a significant role in periodontitis. In previous studies, resveratrol has shown significant results by targeting inflammatory and adhesive markers.

Study of microbial diversity in saliva and plaque samples from caries-free and caries-affected children using denaturing gradient gel electrophoresis.

Background: Recent investigations have shown the possible involvement of bacteria other than mutans group and Lactobacilli in the etiology of caries. Molecular methods have been used to study the microbial diversity in caries-active (CA) and caries-free (CF) children. Among them, denaturing gradient gel electrophoresis (DGGE) is more popular and has been used in the present study.

Synthesis, structural characterization and biological properties of phosphorescent iridium(III) complexes.

Two phosphorescent cyclometalated iridium(III)-triptycenyl-1,10-phenanthroline complexes [Ir(ppy)(tpt-phen)] (1) and [Ir(bhq)(tpt-phen)] (2) {ppy=2-phenylpyridine, bhq=Benzo[h]quinoline, tpt-phen=triptycenyl-1,10-phenanthroline} have been synthesized and structurally characterized. The structure of complex 2 has been studied by single crystal X-ray crystallography. The photophysical properties of complexes in a different solvent have also been investigated.

Characterization and serotype distribution of Aggregatibacter actinomycetemcomitans: Relationship of serotypes to herpesvirus and periodontal status in Indian subjects.

Background: The virulence of Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) in any individual depends on the type of strain of this bacterium. To our knowledge, there have been no studies reported in Indian subjects about A.

Occurrence of Aggregatibacter actinomycetemcomitans in Indian chronic periodontitis patients and periodontally healthy adults.

Background: Aggregatibacter actinomycetemcomitans (Aa), an important primary periodontal pathogen, is known for its strong virulence characteristics that cause periodontal disease. We investigated Aa occurrence in Indian individuals using culture and 16 s rDNA polymerase chain reaction (PCR).

Materials And Methods: A cross-sectional study with 100 participants each in the healthy and chronic periodontitis (CP) groups was conducted.

Prevalence of Herpesvirus and Correlation with Clinical Parameters in Indian Subjects with Chronic Periodontitis.

Objective: The identification of new uncultured species and viruses supports the possibility of combination of the herpes-virus-bacterial periodontal infection for periodontitis. The paucity of data and studies with larger sample size in Indian subjects provides an unclear picture of the presence of the herpesvirus in this population.

Materials And Methods: This was a cross-sectional study consisting of 100 each in the healthy group and chronic periodontitis (CP) group.
