Leonard's vertical technique calls for a straight, vertical approach to the tooth surface. The working edge is kept perpendicular to the surface, giving a direct, controlled path for removing decayed tissue and shaping undercuts without pushing the instrument at an angle. This perpendicular orientation improves cutting efficiency, reduces lateral stress that can gouge walls or threaten the pulp, and helps maintain tooth structure. Using the instrument parallel to the surface would glide without effective cutting, a 45-degree angle would produce an oblique path with a higher risk of irregular walls, and a circular motion is more associated with finishing or polishing steps rather than the vertical removal technique. So the correct direction is perpendicular to the tooth surface.
