What is the definition of diphyodonts?

Diphyodonts are defined as organisms that develop two sets of teeth during their lifetime. This process typically includes a primary set, often referred to as baby or milk teeth, which are later replaced by a permanent set of teeth. This characteristic is common in many mammals, including humans.

Understanding this concept is crucial, as it highlights the difference between diphyodonts and other types of dentition. For instance, other organisms might continuously grow teeth throughout their lives, like certain species of sharks, or they might have a single set of teeth that does not change. The significance of being a diphyodont is reflected in developmental biology and dental health, as it influences how teeth are cared for and how dental conditions may arise over time.
