Human dental plaque is a complex microbial community containing an estimated 700 to
19,000 species/phylotypes. Despite numerous studies analysing species richness in healthy …

The purposes of this study were to examine the compositional changes in the salivary
microbiota according to the severity of periodontal disease and to verify whether the …

Background Oral bacterial communities contain species that promote health and others that
have been implicated in oral and/or systemic diseases. Culture-independent approaches …

Objective Microorganisms play a key role in the initiation and progression of periodontal
disease. Research studies have focused on seeking specific microorganisms for diagnosing …

Chronic periodontitis is an inflammatory disease of the periodontium affecting nearly 65
million adults in the United States. Changes in subgingival microbiota have long been …

Periodontal microorganisms not only colonize subgingival pockets, but also are detected on
various mucous membranes in patients with periodontitis. The object of this pilot study was …

Introduction Apical periodontitis (AP) represents an inflammatory condition of peri-radicular
tissues due to invasion and colonization of bacteria in the root canals. Primary apical …

Objective Microbiota comparisons between healthy and diseased dental tissues have
accentuated the importance of cultivating and identifying bacterial species that play a role in …

Objective To characterize the microbiota of teeth with endodontic treatment failure by 16S
ribosomal RNA genetic sequencing (GS) and PCR at the different phases of the endodontic …

Oral microbiota are among the most diverse in the human body. More than 700 species
have been identified in the mouth, and new sequencing methods are allowing us to discover …
