Deterioration of periodontal status affects declines in mast
Worsening of periodontal status increases the risk of age-related declines in masticatory performance, finds a recent study published in the Journal of Clinical Periodontology.

Researchers aimed to clarify the association between the deterioration of periodontal status and masticatory performance in a longitudinal follow-up study of a general urban population.

This study investigated 663 participants in the Suita study with no changes in the number of functional teeth or occlusal support areas during a 5-year follow-up period. Participants were classified into 3 groups according to changes in periodontal status during the survey period: a recovered group; a stable group; and a deteriorated group. The rate of masticatory performance change was calculated by subtracting the value at baseline from the value at follow-up and dividing the resulting value by the baseline value.

- Median rates of masticatory performance change were -11.7% in the recovered group, -19.2% in the stable group, and -30.8% in the deteriorated group, and these values were significantly different.

- Multiple regression analysis revealed the periodontal status group as an independent variable significantly associated with the rate of masticatory performance change.

In conclusion, deterioration of periodontal status increases the risk of age-related declines in masticatory performance.
