In order to appropriately carry out a longitudinal assessment of periodontal attachment loss in individuals with untreated periodontitis, reliable criteria for determining "real" changes in attachment level (AL) are required. In the present study, 25 subjects were to be examined every 2 months for up to 2 years to determine changes in AL and to relate(More)
Invasive species increasingly threaten global biodiversity with faunal homogenization, and are of specific concern in the highly diverse aquatic systems of the Southeast United States. However, patterns of invasion and variables influencing invasion success remain poorly understood. This study followed the introduction, establishment, and invasion processes(More)
Attachment level or pocket depth measurements are used to detect change in periodontal attachment. However, measurement error limits their usefulness for this purpose. The aims of this study are twofold. The first aim was to test the assumption, used in previous reports of measurement error, that attachment level measurements are normally distributed. The(More)
