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

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 sites per tooth. Dental subgingival plaque samples were taken in the deepest pocket per arch in the maxilla and mandible. DNA analysis was performed using DNA-strip technology. Pearson's correlation coefficient was used for statistical analysis. Results: Porphyromonas gingivalis and Tannerella forsythia were detected at high level of 80% and 82% respectively. F nucleatum revealed a rate of 94%. Bacterial load significantly increased by increasing mean probing depth of the examined sites. Pearson's coefficient was the highest for Pg (r=0.62, p=0.0001) and the lowest for Cg (r=0.08, p=0.04). The bacterial load significantly increased by increasing the number of bleeding sites; Pearson's coefficient varied from r= 0.14 for Pg (p=0.01) to r=0.39 for Tf (p=0.001). Conclusion: It was confirmed the presence of main putative periodontal pathogens detectable in Saudi periodontal subjects, also providing a comprehensive view for correlation of these putative periodontal pathogens with the increase in probing pocket depth to the presence and load of all the bacterial species.

Oleuropein and oleic acid: A novel emerging dietary target for human chronic diseases

The human chronic metabolic disease is predominantly associated with the disturbance in the lipid, proteins and nucleic acid biological balance due to the attack of free radicals generated from oxidative stress. Currently, the available synthetic antioxidants are synthesized by food industries are very effective and inexpensive but as chronic use, it exhibits many toxicological health effects like synthetic drugs. Hence, plant origin antioxidants gained increasing attention all over the world. In this regards, Olive tree (Olea europaea L.) belongs to Oleaceae family and its by-products such as olive leaves and olive oil are highly focused by many researcher due to its potential therapeutic effects in a reversal of various chronic diseases without any side effects. Oleuropein and Oleic acid are the major components in the olive by products and attributes olive as a holly natural remedy and also olive oil considered as a potential food ingredient in the Mediterranean diet. The fat content in olive fruits is higher than olive leaves. Whereas, the protein ratio is higher in olive leaves and more abundance of Oleuropein, which contributes major health benefits as compared to olive oil. Oleic acid with high MUFA ratio contributes to the major health benefits of olive oil to several human chronic diseases.
