Periodontal disease and Helicobacter pylori infection: a community-based study using serology and rapid urease test.

Aims: The aims of the present study were to assess the prevalence of periodontal disease and Helicobacter pylori (H. pylori) infection and their associations within a predefined Indian population.

Methods: A community-based cross-sectional study of 500 selected individuals using a questionnaire, oral examination, rapid urease testing of dental plaque, and serological examination for immunoglobulin G antibody to H.

Management of crown root fracture by interdisciplinary approach.

Fracture of tooth after trauma is distressing to a person because of the discomfort and pain due to pulpal injury. Crown root fractures of anterior teeth cause concomitant periodontal injury and there will be concern about appearance, and aesthetics. Management of pulpal and periodontal tissue relieves pain and restoration of tooth form regains patients confidence.

Antimicrobial photodynamic efficiency of novel cationic porphyrins towards periodontal Gram-positive and Gram-negative pathogenic bacteria.

The Gram-negative Aggregatibacter actinomycetemcomitans and Fusobacterium nucleatum are major causative agents of aggressive periodontal disease. Due to increase in the number of antibiotic-resistant bacteria, antimicrobial Photodynamic therapy (aPDT) seems to be a plausible alternative. In this work, photosensitization was performed on Gram-positive and Gram-negative bacteria in pure culture using new-age cationic porphyrins, namely mesoimidazolium-substituted porphyrin derivative (ImP) and pyridinium-substituted porphyrin derivative (PyP).
