Final answer:
Mandibular molars are commonly radiographed using the parallel technique, which produces images with minimal distortion.
Step-by-step explanation:
Mandibular molars are commonly radiographed using the parallel technique. This technique involves placing the radiograph film or sensor parallel to the long axis of the teeth being imaged, while the central beam of the X-ray is directed perpendicularly to both the film and the teeth. This method is favored for its ability to produce images with minimal distortion compared to other techniques such as the bisecting angle, where the X-ray beam intersects the angle formed by the film and the long axis of the tooth.
