This study was conduct at Academic charity teaching hospital and Khartoum teaching dental hospital, in the period from December 2005 to April 2007.
This study was done to number of (120) patients, 30 patients for each technique, by using different types of dental machines (Philips, Siemens & Shimadzu).
This thesis had studied different anatomical finding and different technical faults by using different type of techniques (periapical, occlusal, lateral /oblique and O.P.G).
This study aimed to choose the best and suitable technique use for detecting pathology, and also to evaluate and compare between the dental techniques to find out the best technique used for each case.
The results of this study was that the periapical examination is the best technique to demonstrate the tooth and it’s main tissue, and it cause less technical fault compare with the other techniques. Also O.P.G is the superior technique when demonstrating the surrounding structures of the teeth.
