Evaluation of role of periodontal pathogens in endodontic periodontal diseases.

Abstract

This study aimed to correlate periodontal pathogens in endodontic periodontal diseases. This study was conducted on 40 patients of both genders. All the participants were obtained from department of endodontics and periodontology with history of endo-perio lesion in same teeth. Polymerase chain reaction was performed and correlation was established. This study included 18 males and 22 females. The mean age of male was 42.5 years and female was 41.3 years. Specimens of <i>Tannerella forsythia</i> were isolated from 94% endodontium and 92% periodontium, <i>Porphyromonas gingivalis</i> from 71% endodontium and 55% periodontium, <i>Aggregatibacter actinomycetemcomitans</i> from 12% endodontium and 58% periodontium. The difference was significant (<i>P</i> < 0.05). Bacteria in endodontic-periodontal infection confirmed statistically significant correlation between absolute quantitation of <i>T. forsythia</i> and <i>P. gingivalis</i> (<i>r</i> = 0.412, <i>P</i> < 0.05), <i>P. gingivalis</i> and <i>A. actinomycetemcomitans</i> (<i>r</i> = 0.524, <i>P</i> < 0.05), and <i>T. forsythia</i> and <i>A. actinomycetemcomitans</i> (<i>r</i> = 0.427, <i>P</i> < 0.05). There was correlation between targeted bacterial species levels from concurrent endodontic-periodontal diseases. Thus, it can be suggested that dentinal tubules may be the pathway for spread of bacteria.
