L'important c'est d'enlever la plaque dentaire, sur laquelle sont fixées les bactéries
Pour info, ce n'est pas ce qui est écrit dans le pdf posté par pal0uf dans ./43.
J'avais dit que je n'ai fait que survoler le contenu de ce lien. C'est marrant comment ça contredit tout ce qu'on m'a appris aux cours.
Le document relativise l'importance du brossage de dents (l'enlevement de la plaque, en gros) au sein des facteurs ayant soi disant permis la baisse d'incidence des caries. Et il dit pourquoi. Ca ne m'a rien l'air de particulièrement révolutionnaire.

Mais on y trouve aussi:Tooth-brushing with fluoride toothpaste seems tohave a preventive effect on caries risk
more
frequent tooth-brushing with a fluoride dentifrice and
good oral hygiene seems to be associated with a reducedcaries risk.
Oui, ça ne contredit ni ce que je dis ni ce que l'auteur du pdf dit. On ne sait pas exactement si c'est le fluor ou le brossage puisque les études sont toujours avec des gens qui se brossent les dents avec un dentifrice fluoré. Et la corrélation est faible.
Pour ceux que ça intéresse, les résultats sur le truc en question, dans l'étude postée par Nhut :
title
Question 6: Tooth-brushing and children ages
less than eighteen.
There is a fairly large literature iden-
tified in the initial search that investigates the effects
of tooth-brushing on caries risk. The results of the re-
view are equivocal, in that some studies find a strong,
consistent relationship between brushing and/or mea-
sures of oral hygiene and caries incidence/prevalence,
while other studies do not find this association. Some
studies report that more brushing is associated with
higher caries rates.
The results of multivariate analyses where avail-
able also are inconsistent. Other variables that often are
significantly related to caries prevalence and incidence
include use of other forms of fluoride (such as mouth
rinses and fluoride tablets), regular dental visits, SES,
total sugar consumption, and frequency of snacking.
Overall, there is a weak relationship between frequency
of tooth-brushing and decreased dental caries. Further-
more, because almost all of the studies report that teeth
were brushed with a fluoride dentifrice, it is difficult to
distinguish whether the effect of tooth-brushing is ac-
tually a measure of fluoride application or whether it is
the result of mechanical removal of the plaque.
Question 7: Tooth brushing and adults ages
eighteen and over.
In contrast to the literature on chil-
dren, the literature on the relationship between caries
and tooth-brushing among adults is quite small. The
most frequent indicators of caries, DFMS/T and Root
Caries Index (RCI), are limited by being measures of
accumulated disease. Therefore, it is not surprising that
the data regarding the association between caries and
tooth-brushing among adults are equivocal, with some
studies supporting this relationship and others not dem-
onstrating a significant relationship between caries and
tooth-brushing. Overall, the evidence is so limited that
no conclusions can be drawn from the existing litera-
ture, although the literature does provide some weak
evidence of an inverse association between oral hygieneand root caries
