Abstract

Abstract:

BACKGROUND: The limitation of periapical film in root canal therapy has been gradually acquired. However, study addressing correlated case and the valid in vitro model was few reported.
OBJECTIVE: To evaluate the limitations of periapical film in root canal therapy.
METHODS: Through a tooth needed to pull out and make use of canal obturation in vitro model, the value of periapical film in root canal therapy was analyzed.
RESULTS AND CONCLUSION: The tooth originally needed to eliminate has been retained. There were comparatively large differences between canal obturation from different angle in vitro models. Periapical film can not only reflect periapical pathological changes, but also canal obturation.
