We felt then and still feel that such a box is necessary for the protection of the operator and also of the patient from the dust of these abraded nails. Frequently, this dust may contain bacterial and fungous elements, and distribution patterns of dust dispersion after high-speed abrasion are very extensive.

Showing plastic box for protection of operator and patient during high-speed abrasion of fingernails and toenails.

The proposed wide-mouth test tube held at an angle to the grinding burr was easy to use; it did offer material for culture, but provided only partial
