AMERICAN DENTAL CONVENTION.
THIRD DAY-MORsISG SESSION.

| BIsT PREPARATION or GOLD FOR FILLING TEETH.
On motion Of DR.. TAFT the Convention sgeed to
close the discussion upon the subject at ~ o'clock.
Dr. Dixon of POtsvile, Pa was fully Satisfied that
those who were in the habit Of using crystalline gold
were capable Of IN iking the best filings with shat
substance, while Others who bad not had much expe-
| Renee could do better th foil. He opposed,
however to shifting about from ono substance to an
othtr and prscticog experiments upon their patients
| who nsst suffer thereby The expsnIn. ming ought
~ be left 10 those who could DO 1t without running
! inks He had lot used crystalline gold much from
tie fac. that be had Lot the physical strength that
seemed to be required for its use
Dr. ROBERTS of Newly rk eaid that there were rad
cas m the GENITAL profession well ae in politics. He
had tried eve yhDg for filling, and be HAD found that
in some case sponge crystalline gold could be used
where foil cOuld not be used well, while in other
cases 'oil best adapted He prac.iced the
| eclectic principle in this reepect.
DR.. KisGsBuRY though he believed both substances
were good prefened gol' foil He thought there
dpO ition ascrihe too much to sponge gold, though
in cases, doubt most excellent work could be
done.
/ Dr. BrcXisGHAM Of Philadelphis made some crit
! osm upon the idea that filing of spopge gold
was perfectly solid The term usually applied
to metals where the particles were held together by
cohesion. That, however, was no evidence that the
largest amount of matter contained in gwen
bulk. In lis own practice he had not been very Cue
! cessful in the of sponge gold, the filings having
broken away in some where they appeared per-
ftctly eOid; they washed away Ike clay. lie thought
vitrefaotion or fusion required TO make q filing
|
where dop of moisture upon the unbuinished su1.3e
was absorbed.
