False. Placing the dot in the slot of the film holder positions the identification dot toward the incisal or occlusal surfaces of teeth. The dot is usually placed in the film holder in such a way that it will be facing the front of the patient's face when the radiograph is taken, so that the identification dot is visible on the radiograph and can be used to orient the radiograph correctly. The apex of a tooth is the tip of the root.
