Genetically predicted DMFS (dental caries) vs Reference (1-SD lower genetically predicted DMFS)

Osteoporosis with pathological fracture · European-ancestry adults

In multivariable MR, genetically predicted dental caries (DMFS) had no significant causal effect on osteoporosis with pathological fracture (OR 1.279, not significant).

Genetically predicted DMFS (dental caries) vs Reference (1-SD lower genetically predicted DMFS)

Osteoporosis · European-ancestry adults

In multivariable MR (adjusted for periodontitis), higher genetically predicted dental caries (DMFS) causally increased osteoporosis risk (OR 1.165, moderate evidence).
