9258800220 2 DENTAL JOBS UPDATE Question 2 Injudicious use of elevator on mesial surface of which impacted mandibular may result in fracture of mandible? • (a) Vertical • (b) Mesioangular • (c) Distoangular • (d) Horizontal Correct Answer: (b) Mesioangular Explanation: Mesioangular impaction of a mandibular third molar positions the tooth with its crown tilted toward the second molar, making the mandible’s angle region more susceptible to fracture. Injudicious use of an elevator on the mesial surface can exert excessive force on the weakened bone, particularly in the angle region, leading to a fracture. Vertical, distoangular, and horizontal impactions are less likely to cause mandibular fracture in this context due to their orientation and bone support.
