Amaçlar: Bu in vitro çalışmanın amacı, mavi ışık
yayan diyot (LED) ve diyot lazer ile foto aktive olan ofis tipi beyazlatma
prosedürleri esnasında altı farklı restoratif materyalin yüzey pürüzlülüğünü
değerlendirmektir.

Materyal ve Metotlar: Bu çalışmada Filtek TM supreme,
Tetric Evo Ceram, Tescera ATL, Clearfill Majesty Esthetic, Durafill VS ve IPS
Empress 2 materyalleri kullanıldı. Yirmi örnek; 
her biri 10 mm çapında 2 mm kalınlığında olacak şekilde teflon kalıp
kullanılarak oluşturuldu. Bütün örnekler rastgele iki gruba ayrıldı (n=10).
Grup 1’ de topikal uygulanan %35’lik hidrojen peroksit LED kullanılarak 20
saniye süreyle foto aktive edildi. Grup 2’ de %46’lık hidrojen peroksit diode
lazer kullanılarak topikal olarak uygulandı. Yüzey pürüzlülüğü değerleri
başlangıç ve beyazlatma işlemleri sonrasında olmak üzere profilometre
yardımıyla ölçüldü. Veriler tek-yönlü varyans analizi (ANOVA), Tamhane's T2 ve
bağımsız t testleri yapılarak istatiksel olarak analiz edildi.

Sonuçlar: Yüzey pürüzlülüğü değerleri test edilen
tüm restoratif materyallerde her iki beyazlatma prosedüründe de artmıştır
(p<0,05). Diode lazer foto aktivasyonu ile beyazlatılan Tescera ATL, LED ile
aktive edilenden daha yüksek yüzey pürüzlülüğü değeri gösterdi (p<0,05).
Fakat diğer restoratif materyaller için iki beyazlatma prosedüründe de önemli
farklılıklar ortaya çıkmadı (p>0,05).

Çıkarımlar: Klinik etkiler in-vivo şartlara bağlı olmasına rağmen ofis tipi
beyazlatma ajanlarının etkileri bilinmeli ve renklenmiş bir restorasyon
beyazlatıldığında veya beyazlatılmış diş ile komşu restorasyon varlığında
dikkatle kullanılmalıdır.

EFFECT OF TWO ACTIVATED BLEACHING TECHNIQUES ON SURFACE ROUGHNESS OF DIFFERENT ESTHETIC RESTORATIVE MATERIALS

Öz

Objectives:
The aim of this in vitro study was to evaluate surface roughness
of six different restorative materials during office bleaching procedures with
blue light emitted diode (LED) and diode laser photo activation.

Materials
and Methods: Filtek TM supreme, Tetric Evo Ceram, Tescera ATL,
Clearfill Majesty Esthetic, Durafill VS and IPS Empress 2 materials were
evaluated in this study. Twenty specimens, 10 mm in diameter and 2 mm thick,
were fabricated from each material using a teflon mold. All specimens were
randomly assigned to two groups (n=10). Group 1 received two topical applications
of 35% hydrogen peroxide for 20 s. And was photoactivated using LED. Group 2
received topical application of 46% hydrogen peroxide using diode laser.
Surface roughness values were measured prior to and following bleaching
procedures by using a profilometer. Data were analyzed statistically, by
one-way-analysis of variance (ANOVA), post-hoc Tamhane's T2 and independent t
tests.

Results:
Surface roughness values for all restorative materials tested
increased after both bleaching procedures (p<0.05). Tescera ATL bleached
with diode laser photo activation showed higher surface roughness value than
LED activation (p<0.05). However, there were no significant differences in
two bleaching methods for other restorative materials (p>0.05).

Conclusions:
Although clinical effects depend on in-vivo conditions, the effects of office bleaching agents should
be known and applied cautiously when a colored restoration is bleached or a
restoration is neighboured with the tooth bleached.
