Quizplus · Accepted Answer

A concavity is a carved-out section or area, like a cave. The smallest concavities found on teeth are called pits, which are pinpoint holes usually occurring along developmental grooves or fossa. Grooves and fossa are also concavities because they are depressed or carved-out areas. Conversely, tubercles and cusps represent the opposite of concavities; convexities. A convexity is defined as an area that bulges out.
