Latar Belakang. Kista radikuler merupakan salah satu jenis kista yang paling sering terjadi pada tulang rahang.
Dengan pemeriksaan radiograf konvensional kadang susah dibedakan dengan lesi lain. Salah satu cara untuk
menentukan diagnosis lesi dengan melihat gambaran lesi dan batas tepi lesi. Radiograf CBCT mempunyai kemampuan
untuk menentukan densitas suatu lesi. Tujuan. Gambaran pola densitas kista radikuler dapat membantu menentukan
gambaran lesi dan batas tepi lesi. Kasus. Laki-laki berumur 28 tahun datang ke dokter gigi untuk cabut gigi 26. 10
tahun kemudian pasien merasa ada benda keras muncul di area 26. Dilakukan radiograf periapikal, ada lesi radiolusen
mendekati sinus maksilaris, kemudian dilakukan pemeriksaan dengan CBCT. Manajemen kasus. Pemeriksaan
radiograf CBCT potongan sagital diperoleh densitas tulang pada batas tepi lesi 626 HU dan 509 HU sedangkan pada
tengah lesi 119-281 HU, pada potongan coronal batas tepi lesi 626 HU dan 749 HU sedangkan pada tengah lesi 84-341
HU, pada potongan axial batas tepi lesi 593 HU dan 665 HU sedangkan pada tengah lesi 66-294 HU. Ada perbedaan
yang jauh antara tepi lesi dengan dalam lesi. Kesimpulan. Gambaran pola densitas pada lesi dan batas tepi lesi dapat
membuktikan bahwa lesi memiliki batas yang jelas dan tegas seperti karakteristik kista.
