Abstract

Objectives: The present study was designed to investigate the
effect of hyperbaric oxygen therapy (HBOT) on improving tooth mobility
during orthodontic treatment using a Periotest. Methods: Twenty
orthodontic cases (n=20) without severe skeletal discrepancies were
used as subjects. For each subject, the mobility of the central and
lateral incisors on both arches (U1, U2, L1, and L2) was measured
immediately before orthodontic treatment (T1), after 12 months of
treatment (T2), and after 3 months from T2 stage (T3) by use of a
Periotest. The sample was randomly divided into two groups (n=10).
The first group was administered HBO for 60 minutes, at 2.5 ATA
(atmospheres absolute) for five consecutive days immediately after
T2 stage, and the second group served as a control. For both
groups the mean values of T1 stages were calculated and compared
to those of T2 and T3 stages in the same group. Results: At T2 and
T3 stages, the periotest mean values have increased for all the teeth
in the second group without HBOT in comparison with those at
T1 stage in the same group. However, in the first group that has
been given HBOT, the mean values have significantly increased at
T2 stage compared with those at T1 stage, but the mean values at
T3 stage have significantly decreased compared with those at T2
stage in the same group. Conclusions: It is suggested that hyperbaric 
oxygen therapy (HBOT) may be useful in reducing tooth mobility
noticed during and after orthodontic treatment.
