Periodontal Disease and Colorectal Cancer

Based on the results of the dental examination and the diagnosis of the periodontal tissue condition according to the new classification of periodontal disease, we performed appropriate non-surgical treatment of periodontal disease, provided oral hygiene instruction, and took a biofilm sample from the deep periodontal pocket. We then collected a sample of the altered mucosa during bowel surgery for colorectal cancer and conducted a microbiological investigation using quantitative culture to compare the presence of Fusobacterium nucleatum and Porphyromonas gingivalis in the pariodontal pocket and altered intestinal mucosa.
