Antimicrobial photocatalysis using bio-hydrothermally synthesized Zinc oxide nanoparticles in the management of periodontitis: a prospective split-mouth, double-blind, randomized, controlled clinical trial.

Background: The antimicrobial activity of metallic nanoparticles (NPs) has been confirmed to fight a broad spectrum of microorganisms, through antimicrobial effects that are amplified when these particles are irradiated with light of the proper wavelength. This is the first study to use phytoconjugated Zinc oxide (ZnO) NPs containing traces of active biomolecules derived from Emblica officinalis (E. officinalis) plant extract in antimicrobial photocatalysis (PCT) during non-surgical periodontal therapy.

Strain Typing of Clinical Isolates by Random Amplification of Polymorphic DNA (RAPD) Analysis.

The aim of this study was to identify and isolate ( ) from clinical samples and to assess the genetic relatedness of the most frequently isolated strains of using random amplification of polymorphic DNA (RAPD) primers GAC-1 and M13. All the clinical samples that grew species, identified and confirmed by polymerase chain reaction (PCR) using genus-specific primers, were considered for the study. Confirmation of the species was carried out by specific PCR.

Molecular mechanism of Escherichia coli H10407 induced diarrhoea and its control through immunomodulatory action of bioactives from Simarouba amara (Aubl.).

Enterotoxigenic Escherichia coli (ETEC) infection is a major cause of death in children under the age of five in developing countries. ETEC (O78:H11:CFA/I:LT:ST) mechanism has been studied in detail with either heat labile (LT) or heat stable (ST) toxins using in vitro and in vivo models. However, there is no adequate information on ETEC pathogenesis producing both the toxins (LT, ST) in BALB/c mice model.

An analysis of the effect of adjunctive use of ozonated oil with a desensitizing agent on dentinal tubule occlusion.

Introduction: Dentinal hypersensitivity (DH), is a commonly encountered clinical problem, the management of which is by two main approaches that involve blockage of nerve activity and tubular occlusion. Desensitizing agents containing arginine and calcium carbonate have emerged effective in occluding tubules. Ozone removes the smear layer and opens up the dentinal tubules for easy penetration of these desensitizing agents.

Comparison of the antimicrobial properties of charcoal-infused and non-charcoal-infused toothbrushes: an in vitro study.

Toothbrushes act as a reservoir for a variety of microorganisms, possibly leading to oral infection. Some manufacturers are marketing toothbrushes that incorporate materials such as charcoal in their bristles and claiming that they reduce bacterial contamination. The present study aimed to explore the antimicrobial nature of charcoal-infused and non-charcoal-infused bristles and to characterize both bristle types physically and morphologically to ascertain any differences that might influence their antimicrobial activity.

Complicated urinary tract infection by .

We report two cases of complicated Urinary Tract Infection, one with nephrostomy tube left and other with bladder outlet obstruction, caused by . Both patients responded well to antifungal treatment along with change/removal of catheters. In both the cases, correct identification of was done by IGS1 sequencing.

Sexual and Reproductive Health Concerns of Adolescents Living with Perinatally Infected HIV in India.

Background: With improved access to highly active antiretrieval treatment, many children with perintally acquired HIV are now able live longer. These children are now reaching into adolescence and sexually active. This qualitative, explorative study examines the sexual and reproductive health (SRH) needs and concerns of adolescents living with HIV (ALHIV) in India.

Diode laser therapy in the management of chronic periodontitis - A clinico-microbiological study.

Introduction: Chronic periodontitis (CP) is an infectious disease resulting in inflammation of the supporting tissues of the teeth with progressive attachment loss and bone loss. This study aimed to evaluate the effect of 980-nm diode laser, as an adjunct to scaling and root planing (SRP) in the management of CP.

Methodology: A total of 40 systemically healthy subjects diagnosed with CP were randomly assigned into two groups G1 (SRP and sham application of laser) and G2 (SRP and laser irradiation) with equal numbers in each.

Dissemination of aerosol and splatter during ultrasonic scaling: a pilot study.

Context: Routine dental procedures produce aerosol and splatter, which pose a potential risk to the clinician and dental personnel, as well as the immunocompromised patient. Reports indicate that the ultrasonic scaler is the greatest producer of aerosol and splatter.

Aims: The study aimed to evaluate the contamination distance, contamination amount and contamination duration of aerosol produced during ultrasonic scaling.
