What is the name of the portion of the image receptor holder that helps the radiographer determine the point of entry?

What will be an ideal response?

Four. Tissue sensitivity or anatomical limitations need to be taken into consideration, and film size is based on the individual. Because in most dental arches, the pathway of the premolars is different from that of the molars, the radiographer must take two bitewing radiographs on the left and two on the right to avoid interproximal overlap which would compromise the image.
