This study was performed to prepare the quantitative method of judging the sensitive
prognosis of chronic apical periodontitis as early as possible. The subjects were 25
cases with periapical radiolucencies of which were treated with endodontic treatment.
Serial radiograptls were taken by standardized method longitudinally. The density slice
function of digital radiographic system were employed for quantitative and longitudinal
assessment of the radiolucent area and the condensing osteitis simultaneously.
Obtained results were as follows:
1. The amount of bone repair after endodontic treatment could be detected
quantitatively by the density slice function of digital radiographic system.
2. Within the 6-week period after root canal filling, the prognosis could be evaluated
by assessment both radiolucent area and condensing osteitis on digital radiographic
system.
3. The pattern of bone repair showed peripheral type in most cases from the 6th
week after root canal filling.
4. In longitudinal change, bone repair showed two patterns; the succeeding reduction
of radiolucent area showing the increase of condensing osteitis in size till 6th week and
following by static state or reduction tendency and the reduction following the initial
increase of both areas.
5. Cases with pulpitis by trauma showed initial increase of condensing osteitis at 2nd
week, marked reduction of radiolucent area and condensing osteitis at 6th week, and
approximately normal bone state 8th week after root canal filling.
