GÝRÝÞ ve AMAÇ: Dental erozyon geri dönüþümü olamayan, çürüksüz sert doku kaybýdýr. Aðýz ortamýnda bulunan iç ya da dýþ kaynaklý asitler dental erozyonun ana etyolojik faktörüdür. Baþta mine dokusu olmak üzere diðer diþ sert dokularý da asitlerden etkilenerek çözünmeler gösterebilmektedir. Ayný zamanda bu çözünme sonucu restorasyonun diþ dokusuna baðlanmasý da etkilenmektedir. Bu çalýþmada normal ve erozyona uðramýþ mine dokusuna uygulanan farklý universal bonding sistemlerin mikrogerilme baðlanma dayanýmlarý incelenmiþtir.
YÖNTEM ve GEREÇLER: Portakal suyunda bekletilerek yapay erozyon oluþumu saðlanan mine yüzeyleri ve saðlam mine yüzeylerinde bir Univeral Bonding Sistem birde total-etch olarak uygulanan bonding sistemin mikrogerilme baðlanma dayanýmlarý karþýlaþtýrýlmýþtýr.
BULGULAR: En yüksek baðlanma dayaným deðeri Single Bond Universal kullanýlan saðlam mine yüzeyli grupta çýkarken en düþük deðerler Single Bond 2 ‘nin kullanýldýðý erozyonlu grupta görülmüþtür.
TARTIÞMA ve SONUÇ: Elde edilen sonuçlara göre erozyona uðramýþ diþlerde mikro gerilme baðlanma deðerleri istatistiksel olarak anlamlý derecede düþük çýkmýþtýr

Anahtar Kelimeler: Dentin bonding, mikrogerilme baðlanma, dental erozyon

INTRODUCTION: Dental erosion is loss of hard tissues on tooth surface with an irreversibl, non-carious lesion. Main ethiological factor of this hard tissue loss is extrinsic and intrinsic acids. Not only the enamel but also the other hard tissues of tooth can be dissolved by these acids. This dissolution process is also effect the bonding of restoration materials to the tooth structures. During the treatment procedures, different restoration materials can be used as an alternative approach. In this study, microtensile bond strength of different universal bonding systems on eroded and sound enamel tissue is evaluated.
METHODS: Orange juice was used to make artificial erosion lesions on two groups. A universal bonding system and a total-etch system were used to evaluate the microtensile bond strength on both eroded and sound enamel.
RESULTS: While, the highest microtensile bond values are obtained in Single Bond Universal used on sound enamel group. In the Single Bond 2 used eroded enamel group has shown the lowest bonding values.
DISCUSSION AND CONCLUSION: According to the results, the microtensile bond strength values of bonding systems on eroded enamel surface is statistically less then sound enamel.
