Helicobacter Pylori in periodontal pockets of chronic periodontitis patients with and without type II diabetes mellitus: a randomized controlled trial

This randomized controlled study evaluated the association of Helicobacter pylori (H. pylori) with chronic periodontitis patients with and without type II Diabetes Mellitus. H. pylori is considered to be a pathogen responsible for gastritis, peptic ulcers and a risk factor for gastric cancer. The aim of the present study was to evaluate the association of H. pylori with chronic periodontitis patients with and without type II diabetes mellitus before and after treatment. The prevalence of H. pylori in periodontal pockets was determined by rapid urease test in a 36 patients, which were grouped as Group 1 (Healthy subjects), Group II (chronic periodontitis patients) and Group III (Chronic periodontitis patients with Type II Diabetes Mellitus), 12 in each group before treatment by collecting plaque samples. After treatment, 12 plaque samples were collected and prevalence H. pylori was detected. Group II and Group III had a significantly higher rate of positive results for H. pylori compared to healthy subjects before treatment. After treatment, H. pylori were not detected in Group II and in Group III Only one of 12 chronic periodontitis patients with Type II diabetes mellitus had H. pylori in the periodontal pocket. The prevalence of H. pylori did not differ significantly between the chronic periodontitis patients with and without type II diabetes mellitus. Meticulous scaling and root planning will reduce the prevalence of H. pylori in periodontal pockets

Herpesviruses in chronic and aggressive periodontitis patients in an Indian population

Many recent studies have assessed the prevalence and role of herpesviruses in the etiopathogenesis of periodontal diseases, which has led to the realization of intricate interactions between viruses and bacteria within periodontal pockets. It has also been shown that the occurrence of herpesviruses may vary depending upon the age of the patient and the race of the population studied. Thus, the present study aimed at detecting herpes simplex virus type 1 and 2 (HSV 1 and 2), Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) in periodontal pockets of Indian patients with chronic and aggressive periodontitis. Subgingival plaque samples (n = 33) were collected from 19 randomly chosen chronic periodontitis and 14 aggressive periodontitis patients. Herpesviruses were detected using multiplex polymerase chain reaction technique. Chronic periodontitis patients revealed presence of HSV-1 in 19 (100) samples, HSV-2 in 3 (15.7), EBV in 15 (78.9) and HCMV in 5 (26.31) samples. Samples from aggressive periodontitis patients showed the presence of HSV-1 in 8 (57.14), EBV in 4 (28.57) and HCMV in 1 (7.14), whereas HSV-2 was not detected in any specimen. In this population, herpesviruses were found more frequently in chronic periodontitis than in aggressive periodontitis patients and their prevalence may vary according to the age and race of the patient
