Functional tooth units

1. Functional tooth units are associated with masticatory performance in humans (r = 0.339, p = 0.038).

   “FTUs were positively associated with the MAI in men and women (r = 0.339, p = 0.038 and r = 0.461, p = 0.001, respectively).”

2. Functional tooth units are associated with masticatory performance in humans (adjusted OR = 0.724, p = 0.029).

   “The number of FTUs (adjusted odds ratio (OR) = 0.724, p = 0.029), tone (adjusted OR = 1.215, p = 0.016), and elasticity (adjusted OR = 4.789, p = 0.038) were independently associated with the MAI.”

1. Functional tooth units are associated with osteoporosis in humans (OR = 0.93, 95% CI: 0.89-0.98, p = 0.004).

   “After adjustment for all covariates, higher FTUs were inversely associated with osteoporosis prevalence (OR = 0.93, 95% CI: 0.89-0.98, p = 0.004).”

1. Functional tooth units lower the risk of obesity in humans.

   “Similarly, for each functional tooth unit present, the PR for obesity was reduced by 4% (95% CI: 0.93-0.99).”

1. Functional tooth units are associated with cognitive function in humans.

   “The regression models revealed a significant positive association between FTUs and cognitive performance among AFT, DSST, and global cognition.”

1. Skeletal muscle mass index is associated with functional tooth units in humans (r = 0.459, p = 0.004).

   “SMI and FTUs were moderately associated in men (r = 0.459, p = 0.004).”
