His clinical duties directly inform his research questions and teaching methodologies, ensuring that his academic contributions remain relevant and grounded in the realities of dental practice.

Dr. Zidan’s research career is focused on the fundamental and applied aspects of dental materials, with a consistent effort to improve clinical outcomes. His work has a significant and lasting impact on the field. The central focus of Dr. Zidan’s research is on “resin bonding and its clinical applications”. This core interest is further defined by a series of specialized keywords associated with his work, which include

Bonding Agent, Dentinal, Enamel, Dentin, Bond Strength Engineering, Composite Resin, and Marginal Gap Formation. This body of work addresses a critical challenge in restorative dentistry: the creation of durable, long-lasting restorations by ensuring a strong and stable bond between the restorative material and the natural tooth structure. His research investigates the physical and chemical properties of these materials and the factors that influence their performance.

Over the course of his career, his research interests have evolved to incorporate modern advancements and emerging topics. In addition to his foundational work on bonding, he has also explored Cad Cam restorations, the application of digital technology in undergraduate education, and natural products to prevent dental caries. This progression demonstrates a scholar who has maintained his foundational expertise while actively engaging with contemporary trends, including the use of innovative digital tools and the exploration of holistic health approaches. His research on natural products for caries prevention, specifically related to Streptococcus mutans, reflects a forward- thinking approach to preventative dentistry.

Dr. Zidan has authored or co-authored numerous publications, including his foundational PhD and MS dissertations, and a collection of peer-reviewed journal articles. The impact of his scholarly contributions can be quantitatively measured by the citation counts of his work. Several of his publications have garnered substantial recognition, suggesting a lasting influence on the field of dentistry. For example, his 2003 article on the retention of complete crowns has accumulated 112 Scopus citations, and his 2004 paper on natural products for dental caries prevention has 81 Scopus citations. Similarly, his 1992 research on the retentive strength of luting cements has 70 Scopus citations, and his 2015 article on the microshear bond strength of resin cements has 72 Scopus citations.

The high citation counts for publications from the 1990s and early 2000s indicate that his work has served as a foundational reference for other researchers and practitioners over many years. His continued publication of highly cited articles, as exemplified by the 2015 paper, demonstrates that his research has consistently maintained its relevance and significance throughout a career spanning several decades.
