FSA: follicular solid/multicystic ameloblastoma, ASA: acanthomatous solid/multicystic ameloblastoma, PSA: plexiform solid/multicystic ameloblastoma, LUA: luminal unicystic ameloblastoma, MUA: mural unicystic ameloblastoma, IUA: intraluminal unicystic ameloblastoma. Kruskal-Wallis test. No statistical significance was observed between Ki-67 and Nuclear Survivin, in subtypes of ameloblastomas.
