Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The surface morphology and chemical composition of commercially pure titanium dental implants and healing abutments exposed in vitro or in vivo to oral bacteria were studied. Implants exposed in vitro to media containing S. mutans and healing abutment retrievals were used to evaluate the effect of early bacterial colonizers. Another dental implant retrieval that failed due to peri-implantitis and implants exposed to an in vitro culture of P. gingivalis were analyzed to assess the effect of late stage colonizing bacteria. Using optical microscopy and X-ray photoelectron spectroscopy, it was determined that both S. mutans and P. gingivalis adversely affected the implant surface, with the early colonizing S. mutans creating conditions leading to more severe corrosion features being observed, including pitting and surface discoloration. Overall, this study demonstrated the ability of bacteria in the oral environment to solely induce changes in the oxidation states of titanium and subsequent corrosion of the implant surface, even in the absence of mechanical loads.
