Although cases like Katzenbach and Heart of Atlanta Motel stretched Congress' power to regulate under the Commerce Clause, United States v. Lopez, 514 U.S. 549 (1995) restricted the Commerce Clause's reach.
Toothbrushes have been around for hundreds of years. In fact, the first known toothbrushes were used about 5,000 years ago and were made of twigs. The Prophet Mohammed introâ¦duced the use of the miswak (toothbrush) to the middle east about 1,300 years ago.
The first electric toothbrush, the Broxodent, was conceived in Switzerland in 1954 by Dr. Philippe-Guy Woog. Woog's electric toothbrushes were originally manufactured in Switzerland (later in France) for Broxo S.A. The device plugged into a standard wall outlet and ran on line voltage.he effectiveness of an electric toothbrush depends not only on its type of action and on correct use, but also on the condition of the brush head. Most manufacturers recommend that heads be changed every three to six months at minimum, or as soon as the brush head has visibly deteriorated.
