Seven hundred and seventy five files of edentulous patients seen at th
e Department of Dental Surgery, University of Nairobi were scrutinized
for the presence or absence of routine radiographs prior to treatment
. 180 (23.2%) had radiographs. 26% of the radiographs had 51 positive
radiological findings. 17.3% were roots, 3.9% were unerupted teeth, 6.
7% were radiopacities and 0.6% were radiolucencies. 52.9% of the radio
logical findings were in the mandible and 47.1% were in the maxilla. I
n the mandible, 44.4% of the radiological findings were in the anterio
r region and 55.6% were found posteriorly. 66.7% of the maxillary radi
ological findings were in the anterior region and 33.3% were found pos
teriorly. Since some of the positive radiological findings such as the
retained roots and unerupted teeth might lead to infection, cysts or
poor dentures fit, it is recommended that whenever possible, all edent
ulous patients be examined radiographically prior to treatment.
