About
David A. Hengehold’s research centers on oral health technology, specifically the design and performance of electric toothbrush heads. His major contribution lies in bridging subjective user experience with objective laboratory testing to evaluate cleaning efficacy over time. In his most cited work, he led a 3-month study comparing the wear progression of two oscillating-rotating brush heads—Oral-B Precision Clean and a store brand—assessing both subject-perceived cleaning and lab-measured performance at multiple intervals. This research provided critical insights into how brush head degradation affects real-world plaque removal, directly informing consumer choices and product development. While his citation count is modest, his work is notable for its practical, applied nature within dental hygiene engineering. Hengehold’s findings help manufacturers optimize brush head longevity and effectiveness, making him a valuable contributor to evidence-based oral care. For students and researchers, his study exemplifies how controlled longitudinal trials can validate everyday product claims, blending engineering rigor with user-centered outcomes.
