Question 139 · LDEK · Benign tumors
Indicate the features of complex odontoma:
1) it is the most common odontogenic tumour;
2) in women it occurs twice as often as in men;
3) the most common location is the lateral part of the mandible body;
4) in rare cases it may erupt and then it is called an erupted odontoma;
5) it consists only of dentine, of chaotic structure;
6) the tumour is painless and slowly growing;
7) Reichart and Philipsen identified four stages of tumour development;
8) higher opacity of tumour tissues when comparing to surrounding teeth is a feature characteristic of late stages of tumour development;
9) lower opacity of tumour tissues when comparing to surrounding teeth is a feature characteristic of late stages of tumour development.
