A FEW PRACTICAL HINTS.
That it is the little things which count. Men who have made, and are making a
mark in the world, no matter what line of work they may be engaged in. recognize,
and let no little detail which might facilitate their work escape their notice, ft is the
perfection of every little thing that goes in to make up a better and a greater whole.
Many dentists have found, by attention constant to method and detail, many little prac¬
tical points that greatly aided them in their work. The following are only a few ideas
suggested by eminent men in the profession.
Some cases are presented to the operator where the teeth have large and well de¬
fined contact points, and are so closely together that it is with great difficulty that the
rubber dam can be applied and forced down to the cervix. A simple way to greatly
overcome this difficulty is to treat the dam after the holes have been punched as de¬
sired, with a good quality of soap. To apply it, first moisten the finger, rub over cake
of soap, then when a thin coating collects on the finger, rub over and around the holes
in the dam on the side which is intended to be next the gums. Another way is to first
moisten the dam, then rub the surface with a disc of soap that is trimmed and is al¬
ways kept in some convenient place in the cabinet.
Cutting down and polishing a cohesive gold filling is so painful to many nervous
patients that they cannot tolerate it. It is a question whether the heat generated by
the sand-paper disk running at such a high rate of speed, together with the large
amount of friction, so heats the filling as to cause it to expand to a certain extent and
loose its solid coaptation to the cavity. This can be almost overcome by merely put¬
ting on the cutting side of the disk a very small quantity of white vaseline or perfumed
oil. It so lubricates the disk that it facilitates the cutting away of the excess of gold,
renders the generation of heat much less and saves the patient from enduring a great
deal of pain.
Sometimes a small portion of the root is left in the process, and presents such a
difficulty of catching hold of it with the forceps, or cannot be removed with the eleva¬
tor, that it is almost impossible to remove it. Oftentimes their removal is made simple
if the canal is open. Cement an ordinary tack in the canal and wait till thoroughly
hardened. Then by catching hold of the head of the tack with the forceps, the root
can be removed.
A dentist, on a busy day, has occasion to use a broach wound with cotton, to dry
out or treat roots, not less than thirty times at least. When a broach has to have the
cotton removed after each operation, much valuable time is consumed. Old nerve
canal instruments should be saved and sterilized, and thirty or forty of these wound
with cotton sometime during the day when time is not taken up. These, when nicely
rolled and placed in the cabinet, will save many minutes of valuable time.
A root broken well off under the gum may present an even surface over which it
is hard to mold inlay wax. and at the same time remove the pin intended for a post for
crown from the canal. A good and entirely satisfactory method to do this is to place
