FAULTY RADIOGRAPHS IN IOPAR
- 1. Poor Radiograph leadsto a loss of Diagnostic Information, loss of Professional & Patients Time Apical End Cut Off Overlapping Of Teeth Cone Cut Herring Bone Effect Foreshortening Elongation Blurred Image Double Image Artifacts Cervical Burn Out High Density Film Low Density Film Low Contrast Film High Contrast Film Film Fog Reticulation Dark Spots Or Lines Yellow/Brown Stain Emulsion Peel Black Film Phalangioma Reason Decreased vertical angulation Rectification Increase vertical angulation Reason Incorrect Horizontal angulation Rectification Central beam of X Ray beam directed perpendicular to facial surface of teeth Reason PID not covering area of interest Rectification Cone is properly placed over the area of interest & the film Reason Back side (lead foil) placed towards cone Rectification Pebbled or front side placed towards cone Reason Increased vertical angulation of cone Rectification Reduce vertical dimension Reason Vertical angulation of cone too flat Rectification Increase vertical angulation Reason Movement of film, patient, tube during exposure Rectification Use film holders Reason Film exposed twice to radiation Rectification Exposed films are Kept in separate labeled compartments Reason Horizontal angle of beam not directed through contact area Rectification Relative radiolucency not to be mistaken as cervical caries Reason Presence of foreign bodies Rectification Patient instructed to remove such items Reason Exposure time too long Developing time too long Reason Too short Exposure Developing time too short Reason Excessive Penetration Under development Reason Insufficient penetration Over development Reason Light leaks in dark room Prolonged development Reason Film Exposed to light Reason Temperature change Weakened fixer solution Reason Dust contact Touching undeveloped film Rectification Set timer correctly Use Darkroom timer Rectification Set Timer correctly Use Darkroom timer Rectification Decrease KvP Use Darkroom timer Rectification Increase KvP Use Darkroom timer Rectification Proper handling of films Rectification Maintain Temperature Replenish fixer solution Rectification Prevent contamination Don’t touch films Rectification Proper dark room Designing. Use time temperature method Reason Abrasion of image during processing Rectification Proper handling of film Reason Exhausted solution Insufficient rinsing Rectification Replenish solution Rinse Sufficiently Automatic Processor Roller Marks Reason Dryer too hot Dryer contamination Rectification Reduce dryer temperature Prevent contamination Reason Patient’s finger incorrectly positioned Rectification Patient’s finger is placed behind the film & not in front of the film Jam or failure of Films to Transport Reason Racks not seated properly Rectification Racks are placed properly
