Abstract
Amaç: Bu çalışmada amacı kurutma ajanı/ kurutma
ajanı olmaksızın mine yüzeyinin hazırlanmasında
asitle pürüzlendirme ve Er:YAG lazerin (QSP ve
MSP mod) fissür örtücünün bağlanma dayanımı
üzerine etkisini değerlendirmek amaçlandı.
Gereç ve Yöntemler: Bu çalışmada 30 adet
çürüksüz daimi diş kullanıldı. Dişler mine-sement
sınırının 2 mm üstünden kesildi ve kökler
uzaklaştırıldı. Dişler meziodistal olarak ikiye ayrıldı.
Elde edilen 60 yarım diş akrilik reçine içine
gömüldü. Mine yüzeyinde fissure örtücüler için 2
mm çapında alan oluşturuldu. Bütün gruplara
Ultraseal XT plus (Fissür örtücü:FÖ) uygulandı.
Örnekler randomize olarak 6 gruba ayrıldı (n:10);
G1:% 37 fosforik asit + Prima Dry + FÖ, G2:% 37
fosforik asit + FÖ, G3: Er: YAG (MSP modu) +
Prima Dry + FÖ; G4: Er: YAG (MSP modu) + FÖ;
G5: Er: YAG (QSP modu) + Prima Dry + FÖ; G6:
Er: YAG (QSP modu) + FÖ. Örnekler 24 saat distile
su içinde bekletildikten sonra bağlanma kuvvetleri,
üniversal test makinesi ile test edildi. Verileri
karşılaştırmak için Kruskal-Wallis ve Mann-Whitney
U-testi kullanıldı.
Bulgular: Gruplara ait bağlanma dayanımları
şöyledir (MPa) G1: 11.33, G2: 9.76, G3: 8.65, G4:
7.72, G5: 4.49, G6: 2.73. Gruplar arasında
istatistiksel fark olduğu gözlendi (p < 0.05).
Sonuç: Mine yüzeyine asit uygulaması, Er:YAG
lazer QSP ve MSP moda göre daha iyi sonuçlar
verdiği görülmüştür. Fissür örtücü uygulanmadan
önce kurutma ajanı uygulanabilir.

Abstract
Background: This in vitro study aimed to evaluate the shear bond strength of a fissure sealant to enamel treated with ER:YAG laser (MSP and QSP mode) and acid etching with /without drying agent.Methods: Thirty permanent human molars were used in this study. The roots sectioned 2 mm coronal to the cementoenamel junction. The crowns were mesiodistally sectioned providing 60 halves that were embedded in acrylic resin. The enamel was flattened and a 2 mm diameter bonding area was demarcated. Ultraseal XT Plus fissure sealant (FS) was applied in all groups. Specimens were randomly assigned to six groups (n=10); G1: 37% phosphoric acid + Prima Dry + FS, G2: 37% phosphoric acid + FS, G3: Er:YAG (MSP mode) + Prima Dry + FS; G4: Er:YAG (MSP mode) + FS; G5: Er:YAG (QSP mode) + Prima Dry + FS; G6: Er:YAG (QSP mode) + FSFS. After 24 hours storage in distilled water, shear bond strength of samples were tested in a universal testing machine. Statistical analysis using Kruskal-Wallis and Mann-Whitney U test was used to compare the respective groups.Results: The SBS results (MPa) were the following: G1: 11.33, G2: 9.76, G3: 8.65, G4: 7.72, G5: 4.49, G6: 2.73. There were significant differences amongs the groups (p < 0.05).Conclusion: The acid etching surface application showed better performance than laser surface treatment in both MSP and QSP mode. Drying agent may be used for enamel surface prior to sealant application.
