This contrasts with the findings of
Trossello & Gianelly (1979), who concluded
that root proximity was present
in 11.4% of the orthodontically-treated
group and 13.4% in the controls. This
might have resulted from the fact that
root proximity was only measured in the
middle part of the roots and the
periodontal status was not reported.
A˚ rtun et al. (1986) reported, after a
subjective screening, 25 out of 400
patients, that had undergone orthodontic
treatment in the past, had root
proximity. It is logical to assume that
orthodontically treated patients have
much fewer sites with root proximity
since orthodontic treatment would try to
correct or avoid situations with root
proximity.
