FARKLI IŞIK KAYNAKLARININ KOMPOZİT POLİMERİZASYONUNA ETKİSİ

Estetik restorasyonlara olan ihtiyac'n artmas'yla birlikte uygun materyallerin geli tirilmesi için birçok ara t'rma yap'lmaktad'r. Bu çal' malar son zamanlarda kompozit materyallerin polimerizasyonundaki dezavantajlar'n ortadan kald'r'lmas' amac'yla polimerizasyon sistemleri üzerinde yo;unla m' t'r. Konvansiyonel halojen cihazlara alternatif olarak ortaya ç'kar'lan sistemlerden biri olan Light Emmiting Diod cihazlar' gerek 's' üretmemeleri gerekse dalga boyu uygunlu;u avantajlar' nedeniyle son zamanlarda kompozit polimerizasyonunda kullan'lmaya ba lanm' t'r. Çal' mam'zda bu cihazlar'n kompozit polimerizasyonunda konvansiyonel halojen cihazlar'na kar ' olan avantajlar' de;erlendirilmi tir. Kullan'lan ' 'kl' cihazlardan 2. jenerasyon Led teknolojisini ta 'yan FreeLight II ,di;er bütün cihazlara 40 sn ' 'nlama süresinde üstünlük sa;lam' t'r. 2 ve 3 mm kal'nl';'nda A1 ve A3 renklerde haz'rlanan kompozit bloklar'nart' 'n'n ve koyu renkte kompozit polimerizasyonunun ' ';'n kompozitin derin noktalar'na penetrasyonunu engelledi;i görülmü tür
