Common Problems in Dental Film Processing and Development

Problem	Causes
Light Radiographs	(i) Processing errors  Under development (temperature too low, time too short)   Depleted developer solution   Excessive fixation  ii)  Under Exposure  Insufficient milliamperaqe   Insufficient kVp   Insufficient time   Film source distance too great   Film packet reversed in mouth
Dark Radiographs	i) Processing errors Over development (temperature too high, time too long)  Accidental exposure to light  Improper safe lighting  Developer concentration too high  ii) Over exposure  Excessive milliamperage   Excessive kVp   Excessive time   Film source distance too short
Insufficient Contrast	Under development  Under exposure  Excessive kVp  Excessive film fog
Film Fog	Improper safe lighting  Light leaks  Over development  Contaminated solutions  Deteriorated film
