Musical Dental Drill

the thought of going to the dentist filled your head with dread, this
may help: a dental drill that plays music! An Indonesian dentist came
up with the musical drill to help anxious kids:

Dhanni Gustiana, a dental surgeon from Purworejo in Central Java, has
modified a conventional dental drill by changing the buzzing sound to
the music from a MP3 player.

"The children are not afraid of doctor, many of them are afraid
of drill. I modified this by putting a toy on the head of the drill
and telling them that the toy will clean their teeth," said Gustiana.
