Excessive intake of sodium caused by high salt diet promotes the expression of inflammatory cytokines anddifferentiation of helper T cells resulting in inflammatory responses. High-glucose diet also contributes to thepathogenesis of periodontitis by inducing changes in the oral microbiome and reducing salivation. However, the effectof a high-salt and glucose diet (HSGD) on the prognosis of periodontitis remains unclear. In this study, a rat modelof experimental periodontitis was established by periodic insertion of absorbable sutures containing Porphyromonasgingivalis and Fusobacterium nucleatum strains into the right gingival sulcus to analyze the effect of HSGD on theincidence and progression of periodontitis. The alveolar bone heights (ABH) was measured with microcomputedtomography imaging of the HSGD- and general diet (GD)-treated groups. The right ABH was significantly decreasedcompared to the left in both groups at 4 weeks after induction of inflammation; however, no significant differencewas noted between the groups. Notably, the ABH in the HSGD-treated group was significantly decreased at 8 weeksafter induction of inflammation, whereas in the GD-treated group, an increase in the ABH was observed; a significantdifference of the ABH was noted between the two groups (p < 0.05). At 12 weeks, recovery of the alveolar bone wasobserved in both groups, with no significant differences in ABH between the two groups. These findings indicatethat the intake of excessive sodium attenuates the recovery rate of the alveolar bone even after the local infectant isremoved. In addition, this study demonstrates the use of HSGD in establishing a new animal model of periodontitis.
