Omori S, et al. - The impact of exercise habits was explored by the authors on periodontal diseases and metabolic pathology in obese men who participated in an exercise and/or dietary intervention program. It was determined that the copy count of T. denticola decreased substantially in the dietary intervention group. No link was reported between the number of periodontal disease-causing bacteria and probing pocket depth (PPD) and bleeding on probing (BOP). Findings illustrated possible improvements in periodontal disease due to exercise.

Methods

• A prospective intervention research was carried out for 12 weeks.
• The enrollment consisted of 71 obese men taking part in an exercise and/or dietary intervention program.
• A total of 50 enrollees were assigned to exercise interventions (exercise intervention group) and 21 subjects were allocated to dietary interventions (dietary intervention group).
• This study was performed prior to and after each intervention program.

Results

• The exercise intervention group revealed that the number of teeth with a probing pocket depth (PPD) ≥ 4 mm considerably decreased from 14.4% to 5.6% (P < 0.001).
• It was also determined that the number of teeth with bleeding on probing (BOP) notably decreased from 39.8% to 14.4% (P < 0.001).
• A substantial decrease was found in the copy counts of Tannerella forsythia and Treponema denticola (P=0.001).
• Data shed light on a positive association between the change in the copy count of T. denticola and the number of teeth with PPD ≥4 mm (P=0.003) and the number of teeth with BOP (P=0.010).
• Moreover, a positive link was depicted between the change in the copy count of T. denticola and body weight (P=0.008), low-density lipoprotein cholesterol (P=0.049), and fasting insulin (P=0.041).
• Nonetheless, the copy count of T. denticola appeared to decrease significantly (P=0.007) in the dietary intervention group.
• No connection was demonstrated between the number of periodontal disease-causing bacteria and PPD and BOP.
