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.
