Prevalence and Molecular Analysis of Novel Newly Identified Periodontal Pathogens in Subgingival Plaque Samples of Saudi Patients with Chronic Periodontitis

Abstract Objective: To evaluate the prevalence of novel newly identified periodontal pathogenic strains in subgingival plaque samples and relate it with bleeding on probing, probing pocket depth and age. Material and Methods: 268 chronic periodontitis patients with a mean age of 46.0 ± 6.0 years were included. The following microorganisms were evaluated: Campylobacter gracilis (Cg), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg), and Tannerella forsythia (Tf). Full mouth examination was registered; the probing pocket depth and clinical attachment level were assessed at six site...
