AIM: The aim of the study is to compare and evaluate the shear bond strength of color changing adhesives Transbond Plus and Blugloo on ceramic surface under different conditions of saliva contamination. METHODOLOGY: Ceramic blocks used in crown fabrication is used for the study. The blocks were divided into two groups; group I– transbond plus, group II–blugloo. Each group was subdivided into: A. No Contamination, B. Contamination with saliva. The procedure of etching and priming of the teeth was carried out according to manufacturer’s instruction. Contamination of the mounted blocks with artificial saliva was performed in the order of the above–mentioned categories. The metal premolar brackets were then bonded using color changing adhesives Transbond Plus (n=20), Blugloo (n=20). After 24 hours the brackets were tested for shear bond strength using a Universal Testing Machine. The results obtained were analysed with Independent Student t Test. RESULT: The bonding performance of Transbond Plus and Blugloo was better in saliva uncontaminated condition. However, the bond strength of Blugloo was relatively higher than Transbond Plus. This may be due to the sealant, Ortho Solo, used in these groups. CONCLUSION: Both the color changing adhesives can be used safely in orthodontic practice since they show acceptable bond strengths. Even though Transbond Plus showed acceptable bond strength during saliva contamination procedures, it was less than that of Blugloo. In situations where extra bond strength is needed on a ceramic surface Blugloo may be preferred.
