The hypothesis that teeth act as reservoirs of micro-organisms for the
colonization of oral implants has recently been stated several times.
The present study aimed at examining, in partially edentulous patient
s with severe periodontitis, whether pockets around teeth and implants
harbored a comparable micro-flora. In 6 patients (3 with refractory p
eriodontitis and 3 with advanced chronic adult periodontitis), plaque
samples were taken from a deep and shallow pocket around both teeth an
d implants for differential phase contrast microscopy and DNA probe an
alysis. The results showed important differences in the sub-gingival f
lora between the 2 disease groups, as well as between deep and shallow
pockets, around both implants and teeth. On the other hand, when pock
ets around teeth and implants with equal depths were compared a striki
ng similarity was observed in the microbial composition. These observa
tions confirm the hypothesis that pockets around teeth act as a reserv
oir and highlight the importance of periodontal health when oral impla
nts are planned.
