The aim of this study was to determine if the microbial composition of supragingival plaque varied with tooth type. The plaque samples and method for microbial analysis were the same as those reported in another study (Haffajee AD, Teles RP et al. J Periodont Res 2008; doi:10.1111/j.1600-0765.2008.01154.x). Stepwise multiple linear regression was used to look for relationships between plaque mass, bacterial species and tooth location. It was found that increased plaque mass occurred on molar and lower incisor teeth when compared with other teeth. Generally teeth with high plaque mass were associated with higher levels of certain bacterial species, although this relationship was not consistent.
