However the authors say it’s the largest evaluate of its type so far. Additionally they tried to account for reverse causation in a separate evaluation and located that this will clarify some, however not all, of the hyperlink noticed right here.
In different phrases, whereas there could also be a real causal hyperlink between poor oral well being and dementia, additional analysis is required to higher perceive the specifics of this relationship, together with the precise mechanisms. which underpin it.
