Radiographic Errors in Intraoral Periapical Radiographs
AN OBSERVATIONAL STUDY
Abstract
Background: Radiographs are considered as pivotal aid in the diagnosis and treatment planning of various Oro-dental pathologies. Changes in the quality of radiographs may lead to misinterpretation, which results in incorrect diagnosis and treatment planning. The technical and processing errors can largely influence the radiographic interpretation. Both paralleling and bisecting angle techniques can have both technical and manual errors.
Aims: To estimate the frequency of radiographical errors in conventional radiographs taken by undergraduate dental students.
Materials And Method: Thousand (1000) dental radiographs taken by undergraduate students were examined. Patient's age ranged between 5 -75 years. X- ray films were examined on X-ray film viewer and were classified according to type of errors and anatomical distribution.
Results: The study aimed to identify common faults encountered during routine radiography. The most frequently observed error was Improper Vertical Angulation. Interns performed better in obtaining radiographs compared to Final year students.
Keywords: Radiographic errors, Dental students, Bisecting angle technique.
