ALTERNATIVE RAOIOGRAPHIC TECHNIQUE FOR ENDODONTIC TREATMENT
Keywords:
endodontics, radiography, technologyAbstract
Objective
The objective of this study was to adapt vertical angles to an extraoral radiographic technique using periapica/ radiographic film so that it can be used in an easy and simple manner.
Methods
Eleven macerated skulls with their respective mandibles were used. Four 1 centimeter stainless steel wires were fixed in the interproximal spaces of the posterior teeth. A protractor was employed to establish the bisector angle between the teeth and the film. A mathematic formula allowed the determination of the vertical angulations for each region. The radiographic images were digitized and measured by specific computer software (UTHSCSA lmage Too/). The statistic analysis employed the "t" Student test.
Results
A difference of 0.477 mi/limeters between the actual length of the stainless steel wire and its image was found in our study and this difference was not clinical/y significant.
Conclusion
Besides the advantage of not affecting the diagnostic quality of the radiograph significantly, the extraoral technique can a/so be efficiently used in a select group of patients.
