Bonding material is a coupling agent required in performing composite restoration on caries and dentine erosion. 4-META is one of the materials often used as bonding material. Bonding material contains solvent agent which promotes monomer infiltration to collagen. The most commonly used solvents are acetone and ethanol. The aim of this studies was to determine the chemical bond strength difference between 4- META with ethanol and with acetone on type I collagen. Materials and methods: The sample of this study was divided into three groups: mixture of 4-META and collagen as control group (C); mixture of 4-META, ethanol and collagen (T1); and mixture of 4-META, acetone, and collagen (T2) as treatment groups. The samples from all groups pelleted using KBr before being analyzed by means of FTIR. One Way ANOVA and Tukey HSD test were used to analyze the results data (p＜0.05). Results: Carbonyl absorbance bands peak (P) value of C group was 75.15, while T1 was 47.91 and T2 was 28,18. The smaller P value, the greater the bonding strength of the chemical. The chemical bond strength of the 4-META and acetone bonding material is greater than soluble ethanol on type I collagen.
