Proteomic analysis of endodontic infections by liquid chromatography-tandem mass spectrometry.

ABSTRACT:

Introduction

Endodontic infections are very prevalent and have a polymicrobial etiology characterized by complex interrelationships between endodontic microorganisms and the host defenses. Proteomic analysis of endodontic infections can provide global insights into the invasion, pathogenicity mechanisms, and multifactorial interactions existing between root canal bacteria and the host in the initiation and progression of apical periodontitis. The purpose of this study was to apply proteomic techniques such as liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the identification of proteins of bacterial origin present in endodontic infections.

Methods

Endodontic specimens were aseptically obtained from seven patients with root canal infections. Protein mixtures wer
