Evaluation of three root canal filling techniques through digital radiograph

Resumo

Endodontic obturation consists of root canal filling
by antiseptic or inert materials that promote a three-dimensional
sealing and stimulate the repair process without interfering with it.
Different obturation techniques and materials have been proposed
to meet this requirement. Objective: To compare the root canal
filling promoted by lateral condensation technique, Tagger's hybrid
technique and McSpadden technique by assessing the filling quality
through digital radiograph. Material and methods: A total of 45
extracted single-rooted human teeth were used and randomly divided
into three experimental groups. After instrumentation, the teeth
were filled by lateral condensation (n=15), Hybrid Tagger (n=15), and
McSpadden techniques (n=15). Then, digital radiographs were taken
with projected increased 10 times, at mesial-distal and buccolingual
directions. Results: Visually, few empty spaces were detected at the
three root thirds of teeth filled by different techniques. However,
statistical analysis (Kruskal-Wallis) found no differences among the
different groups, neither among the different thirds nor between both
incidences evaluated. Conclusion: It was concluded that the three
obturation techniques exhibited similar behavior in relation to the
sealing of the root canal through digital radiograph.
