Identification and assessment of factors that impact the demand for and supply of dental hygienists amidst an evolving workforce context: a scoping review.

Background: This study involved a scoping review to explore factors influencing dental hygienist demand and supply in high-income countries.

Methods: A six-stage scoping review was conducted with separate search strategies tailored to four databases (MEDLINE, CINAHL, Google Scholar, and Google) plus a targeted scan of dental hygienist organization websites. This yielded 2,117 unique citations, leading to 148 articles included in the review.

Dislodgeable foliar residues are lognormally distributed for agricultural re-entry studies.

The Agricultural Reentry Task Force (ARTF) conducted a study to determine if dislodgeable foliar residues (DFR) are either normally or lognormally distributed. This is important because the data are used with worker exposure data, which generally appear to be lognormally distributed, to calculate transfer coefficients that will be used to assess farm worker re-entry exposure. Two chemicals were used for this study.
