%X We established a novel identification method for oral Rothia species using one-step multiplex PCR analysis to investigate whether the monitoring of oral <em>Rothia</em> species levels is useful for peri-implantitis risk assessment, and to examine the oxygen concentration that these organisms need for growth <em>in vitro</em>. The mean number and proportion of <em>Rothia </em><em>aeria </em>in peri-implant sulcus fluid (PISF) samples was significantly higher in the healthy implant group than in the peri-implantitis group (P &lt; 0.05). Moreover, <em>R. aeria</em> under aerobic conditions vigorously grew compared with those under anaerobic conditions, and this organism grew only at the upper layer where high oxygen concentrations existed in a semi-liquid nutrient medium. Therefore, the monitoring of <em>R. aeria</em> levels may be suitable as an indicator of healthy peri-implant tissue conditions for the prevention of peri-implantitis.
