The mean Ki-67 and MCM-2 expressions in odontogenic cysts were 12,17  ±  4,49 and 19,17  ±  3,76 in RCs (Figures 7(a) and 7(b)), 7,43  ±  3,99 and 7  ±  4,25 in DCs (Figures 8(a) and 8(b)), and 16  ±  13,46 and 15,43  ±  14,04 in KCOTs (Figures 9(a) and 9(b)), respectively. The gene discussed is MKI67; the disease is odontogenic cyst.
