Abstract


Objective: To perform a chemical analysis of the surface of dental implants after contact with surgical gloves by scanning electron microscopy and energy dispersive spectroscopy (EDS) and to correlate the findings with literature data. Materials and methods: Five commercially pure titanium implants submitted to surface treatment by acid attack and one pair of sterile latex gloves were selected. First, the implant and gloves were analyzed separately by EDS in order to observe the chemical elements on their surfaces. Next, the implant surface was put in contact with the surgical glove and analyzed by EDS to identify possible contaminants left by the latex glove. Results: Calcium, Zn, Mg, S, Si, and Nb were detected on the surface of the surgical glove, with Ca and Zn being the predominant elements in all samples. Titanium was detected on all implants; two implants only exhibited this element as described by the manufacturer and three contained small amounts of Ca, but Ti was the prevalent element. After contact of the implants with the surgical glove, elements that had not been detected on the gloves and implants during separate analysis, such as S, Zn, Si and Ca, were found. Conclusion: The present results and literature data permit us to conclude that the surface of titanium implants was contaminated after contact with surgical gloves and that inorganic chemical elements can modify the titanium oxide layer, resulting in possible interferences with the process of osseointegration.
