You will need to take a retake on your patient's mandibular right premolars because of overlapping.The overlapping is more excessive toward the mesial of the film than the distal of the film.What do you need to do to prevent this error on the retake?
A)Correct horizontal angulation,direct the PID more toward the distal.
B)Correct horizontal angulation,direct the PID more toward the mesial.
C)Correct vertical angulation,decrease vertical angulation.
D)Correct vertical angulation,increase vertical angulation.

If the overlapping is more pronounced in the anterior half of the image,the PID was pointed too much from the distal toward the mesial.To correct this error,you would need to direct the PID more toward the distal until the x-ray beam is directed through the interproximal contacts.If the overlapping is more pronounced in the posterior half of the image,the PID was pointed too much from the mesial toward the distal.To correct this error,you would need to direct the PID more toward the mesial until the x-ray beam is directed through the interproximal contacts.In order to prevent foreshortening,you would need to decrease vertical angulation.In order to prevent elongation,you would need to increase vertical angulation.
