A benign tumor that grows from the pulp tissue inside a tooth.
From Latin 'dentis' (tooth) + Greek '-oma' (tumor or growth). The suffix '-oma' is used in medical terminology to indicate any kind of swelling or abnormal growth of tissue.
Dentinomas are incredibly rare, but they show how tumor names follow predictable patterns in medicine—once you know the root 'dentis' means tooth and '-oma' means tumor, you can understand hundreds of other medical conditions just by building the term piece by piece.
