What type of stroke is characterized by a slanting motion?

The correct answer is characterized by a slanting motion, aligning with the term "oblique." In the context of periodontal instrumentation or brushing techniques, an oblique stroke involves a diagonal approach, combining both horizontal and vertical movements. This method is often employed to effectively clean surfaces, particularly those that are more challenging to reach, such as the buccal and lingual surfaces of the teeth. The oblique stroke can enhance plaque removal and facilitate better access to interproximal areas, contributing to improved oral hygiene.

In this context, while other strokes may refer to different specific motions—like horizontal or vertical referring to straight lines across the surface—oblique captures the essence of a slanting motion, which is integral in various dental practices for thorough cleaning and maintenance.
