Abstract:
Aim: To manufacture a clinical simulation apparatus
for the undergraduates' endodontic radiography
teaching
Objectives:
• To provide a model for teaching of parallax
method using Kelly's forcep
• To provide a model for undergraduates to
practice radiographic localization employing
parallax method.
• To allow students to practice taking
radiographs in a way that simulates the
clinical situations with a good diagnostic
quality
Methods: Impressions of a dentate arch
(maxillary and mandibullary) were used to form a
stone cast. A section of the cast, in the area where
the natural teeth were to be placed, is sectioned and
removed. Three maxillary extracted teeth (canine,
first and second premolar) were selected and
mounted with acrylic resin at the sectioned area. The
resin was cured in a light box. The arches were
mounted in a phantom head with a placement of
rubber cheek. The first premolar was isolated with
rubber dam. The intraoral holder (Kelly's forcep)
was attached to a robotic arm. The students were
taught the correct angulations of the x-ray cone for
the paralleling technique and parallax method using
Kelly's forcep during root canal treatment.
Results: All students managed to complete the
exercise and were considered competent when they
produced acceptable quality of radiographs.
Conclusion: The model described was improvised
from a model that has been used during the past 2
years for undergraduates' endodontic courses. It has
been well accepted as it simulates the clinical
situation more closely than was possible previously.
