Dr. Jenkins, of Dresden, says, "I use Tg in soft, imperfect teeth, of
which there are plenty in Germany, because it has pliability,
adaptability, slight susceptibility to thermal changes, makes a
water-tight joint, very useful at cervical margins, and can be used with
a minimum amount of pressure. When packed dry and with the gold next to
the tooth, discoloration occurs only on the surface; packed wet, the
whole discolors. I do not attribute its success to electrical action.
Lay a sheet of No. 4 tin on a sheet of No. 4 non-cohesive gold, fold so
as to keep the gold on the outside; use the strip with lateral pressure,
doubling it upon itself."

Dr. A. H. Thompson: "After several years' successful use of tin-gold, I
commend it for approximal cavities, cervical margins, and frail walls.
The oxid formed penetrates the enamel and dentin; if a filling wears
down, cover the surface with gold."

Dr. Pearson: "I do not like tin and gold in alternate layers. I prefer
No. 10 tin foil."

Dr. James Truman: "I believe that tin-gold has a positive value as a
filling-material."

"I prepare tin-gold by taking a sheet of No. 4 non- or semi-cohesive
gold, fold them together (or twist them) so as to have the gold on the
outside, and then fill any cavity with it. Since adopting the above
combination I have almost abandoned amalgam. This is recommended on
account of its density, ease of insertion, capacity for fine finish,
non-conducting and non-shrinking qualities, and compatibility with
tooth-substance. Those who have not used it will be surprised at the
rapidity with which it can be manipulated. It may be employed in any
cavity not exposed to view, also in crown, buccal, and approximal
fillings which extend into the occlusal surface, as it offers an
astonishing resistance to wear. It can be used anywhere that amalgam
can, and with more certainty of non-leakage, and it has the additional
advantage that it can be finished at the same sitting. Care is necessary
in manipulating it, so as to avoid chopping. I use hand pressure when
filling, and the mallet to condense the surface." (Dr. A. W. Harlan,
_Independent Practitioner_, 1884.)

"Pure tin foil is employed in connection with non-cohesive gold in
filling proximal cavities in bicuspids and molars; a sheet of gold and a
sheet of tin are folded together." (C. J. Essig: "Prosthetic
Dentistry.")

Dr. Benj. Lord says, "A combination in which I find great inte
