The aim of this study was to assess the ability of taking and processing of intraoral periapical radiographs (IOPA) by the dental college students.
Materials and Methods: This study was conducted in the Department Of Oral Medicine And Radiology Meenakshi ammal dental college Chennai. A total of 2013 periapical faulty radiographs were included in the current study which was taken and manually processed by dental Students. All intraoral periapical radiographs were taken using bisecting angle technique with Kodak E speed film, 70kvp, 8MA and exposure time 0.4 seconds.
Results: A total of 2013 faulty radiographs were included in the study of which 1008 were of maxillary radiographs which had cone cut in 35.4%, elongation 32.5%, foreshortening 1.7%, overlap 5.7%, reverse film 0.4%, incorrect film placement 21%, light 6.9%, dark 3.7%, finger print 0.1%, light exposed 1.8%, light spots 0.2%, dark spots 0.3%, brown stains 3.2%, artifacts 0.9%. Out of 1005 mandibular radiographs, radiographic faults among the mandibular radiographs had cone cut in 46%, elongation 11.4%, foreshortening 0.6%, overlap 4.2%, reverse film 0.6%, incorrect film placement 36.9%, light 3.2%, dark 2.9%, light exposed 1.2%, light spots 0.2%, dark spots 0.3%, brown stains 3.6%, artifacts 0.6%.
Conclusion: This study has classified and evaluated all the faults that can occur in recording a dental radiograph. Hence this will help us to overcome the faults in practising dental radiograph by the dental students.
