About me

Masoud HassanZadeh
I am a dentist working in my own practice in Drachten, the Netherlands. Microscopes are my passion, and through their use—both intraorally during treatment and extraorally on extracted teeth under high magnification—cracks have become a central focus of my work.

Why cracks?
Almost every tooth contains cracks, making them an unavoidable part of our professional lives; therefore, understanding how cracks start, propagate, and eventually lead to tooth fracture is essential.

Let’s get in touch
If you frequently encounter tooth cracks in your role as an oral healthcare provider and are unsure how to manage them or when to intervene, I invite you to connect. Take a look at my publications, share cases you find challenging, or join a hands-on or online course to learn more about diagnosing and treating cracked teeth.
"My dream is to reach and support many dentists who struggle with diagnosing and treating cracked teeth, helping them find clearer treatment pathways and reduce failures such as tooth fractures."
