Abstract
It is reported that treatment of oral disease before bone marrow transplantation (BMT) decreases the incidence of infectious complications during BMT. However, we often hesitate to treat postendodontic periapical lesion without a sign of inflammation.
In this study. we examined 24 patients with asymptomatic post-endodontic periapical radiolucencies of 78 patients for pre-BMT dental assessment between October 1987 and December 1993 at Department of Oral and Maxillofacial Surgery, Nagoya Daini Red Cross Hospital.
The purpose of this study was to compare the effect of dental treated group (extraction or root canal retreatment) with non-treated group of periapical lesion on the frequency of infectious oral complications during BMT.
We examined (1) the number of days when the patients temperature was greater than 38.0°C (2) the number of days when the absolute neutrophil count was less than 500/μl and (3) local signs and symptoms associated with odontogenic infection, such as swelling, pain and sensitivity.
There was no significant difference in both systemic and local infectious complications between treated group and non-treated group.
These results suggested that asymptomatic post-endodontic periapical radiolucencies might not always increase of infectious complications during BMT.
