Study Arms:
- Pre-operative brushing (Pilot Portion) (Type: EXPERIMENTAL): -Toothbrushing 3 times/day for at least 5 days preoperatively using a 0.12% chlorhexidine solution
- Pre-operative & Post-Operative Brushing (Esophageal Resection) (Type: EXPERIMENTAL): * Toothbrushing 3 times/day for at least 5 days preoperatively using a 0.12% chlorhexidine solution~* The intensive toothbrushing regimen and chlorhexidine mouthwash will be continued for the duration of the hospitalization or a minimum of 5 days postoperatively in the study group.
- Pre-operative & Post-Operative Brushing (Lung Resection) (Type: EXPERIMENTAL): * Toothbrushing 3 times/day for at least 5 days preoperatively using a 0.12% chlorhexidine solution~* The intensive toothbrushing regimen and chlorhexidine mouthwash will be continued for the duration of the hospitalization or a minimum of 5 days postoperatively in the study group.
