is the correction of irregularities of the teeth, many more
X-ray investigations would be required and the question of
the purchase of an X-ray apparatus would then arise.
Of the 6,800 fillings, over 400 consisted of porcelain
restorations in front teeth, which were inserted with the aid
of a rubber dam, thus rendering the field of operation absolutely
dry, the process is rather protracted, but the results
achieved are excellent.
During the year only three front teeth have been treated
with a devitalising agent, which renders the tooth dead and
shortens its period of usefulness. In all other cases a procedure
has been adopted known as " pulp capping," which
consists in capping an exposed nerve in a special way and
after a period has elapsed, of finally filling the tooth over this,
in the usual way, thus preserving the life of the tooth. Over
100 cases have so far been treated in this manner and there
has been only one apparent failure.
