Examining the enamel surface with the Atomic Force Microscopy (AFM) enables more precise registering and defining of the changes of enamel surface structure and of microhardness. This method can be used to compare the efficiency of application of different preventive and therapy materials and medicaments in dentistry. Under the influence of coca cola, a change of crystal structure and nanomorphology on enamel surface occurs.

The trial was conducted on a total of 40 extracted teeth which were divided into two groups treated with the solution of coca cola during 5 minutes, and then prepared and tested with a standard AFM procedure, type SPM-5200. Quantitative analysis was performed by comparing the roughness parameters (Ra) of treated and non-treated sample.
