Periodontal disease in preoperative patients with digestive cancer: a retrospective, single-institution experience in Fukui, Japan

Abstract

Background: The careful preoperative oral assessment may be useful for safe surgery under general anesthesia. The purpose of this study was to investigate the presence of periodontitis in patients with malignant digestive disease before surgery under general anesthesia. Methods: Patients with digestive malignant disease who underwent periodontal examination and orthopantomograph examination for preoperative oral health assessment were participated. The authors investigated the patients’ general characteristics and clinical oral information, including the presence of periodontitis. Results: One hundred twenty patients participated in this study. The mean and standard deviation of the number of teeth was 20.8 ± 8.2, and there was a statistically significant correlation between age and number of teeth. The periodontal pocket depth was 3.0 ± 1.0, and mobile teeth were observed in 62 patients. There was a statistically significant correlation between number of teeth and number of mobile teeth. However, there was no significant difference between the age of patients without mobile teeth and the age of patients with mobile teeth. Conclusions: This retrospective study performed in single-institution clarified the presence of periodontitis in patients with malignant digestive disease before surgery. Regardless of age, it is important to assess the oral health, including periodontitis, for safe surgery under general anesthesia.
