BACKGROUND: The presence of pathogens in dental plaque is a risk factor associated with postoperative pneumonia in esophageal cancer patients. The effectiveness of pre-operative dental brushing to decrease the risk of postoperative pneumonia in esophageal cancer patients was evaluated prospectively. METHODS: A total of 86 thoracic esophageal cancer patients who underwent an esophagectomy were investigated. Patients were divided into 2 groups: the control group (41 patients) and the pre-operative dental brushing group (45 patients). The patients in the brushing group were assigned to brush their teeth 5 times a day. After the operation, the frequency of postoperative pneumonia and need for tracheostomy for pulmonary treatment was calculated. RESULTS: Postoperative pneumonia was decreased markedly from 32% to 9% (P = .013), and the frequency of postoperative pneumonia requiring tracheostomy decreased from 12% to 0% in the dental brushing group, respectively. Limiting the patients who had positive pathogenic bacteria in their dental plaque on their admission, the frequency of postoperative pneumonia was decreased from 71% (5 of 7 patients) in the control group to 17% (2 of 12 patients) in the dental brushing group (P = .045). CONCLUSION: Frequent pre-operative dental brushing is performed easily and seems to prevent postoperative pneumonia in esophageal cancer patients. Copyright 2010 Mosby, Inc. All rights reserved.
