Followed are the results of the study:. The rate of error was the highest in canine from both maxilla and mandible when used by the bisecting angle technique.. The rate of error was the highest in premolar from both maxilla and mandible when used by the paralleling technique.. The technical error was occurred most frequently in elongation.. The rate of error and distortion was higher in the bisecting angle technique than in the paralleling technique.. The processing error was occurred most frequently in light film.. In applying radiographic techniques, the subjects indicated that the vertical angulation of central radiation in the bisecting angle technique and the oral fixation of film holder in the paralleling technique were the most difficult.,fz XPSET Bisecting technique, Paralleling technique, Technical error, Processing error, Film holder B " š;ö & &š jæšb òö & V&>& ôš jr. š ~ ~ V&~ Ï ÊV *š Bº ò~ î Ëçš &b~. ò~ îj šv *š Bº ;{ š *B>Ú ~º, ;{ j *šb &æ òj Ï~æò jj N æ~º š OÒF Òš. ß ;òöbº Gn &Vš¾. /š &Ë ãö& ôf ò~ ßWç O ÒF Òö~ ~š&.
