Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to evaluate clinically, the general
disintegration, gross fracture, marginal breakdown, and surface texture
in Class I and Class II restorations of four temporary filling materials
having widely varying physical properties. They were zinc oxide-eugenol
(Temrex), zinc oxide-rosin eugenol (Caulk’s), zinc phosphate
cement (Tenacin), and silico-phosphate cement (Kryptex). Powder-liquid
ratios and all manipulative procedures for each of the four materials
were standardized. Compressive strength, solubility and abrasion resistance
tests were carried out in the laboratory on the same standardized
mixes used in the clinical part. A total of 137 standardized cavities were
prepared in deciduous and permanent teeth of 37 children and restored
with the four materials in an effort to equalize the distribution between
the four quadrants. Rubber base impressions were taken as permanent
records for evaluation at the one week, one month and three months
observation visits. Zinc oxide-rosin eugenol (Caulk) exhibited the
least resistance to disintegration and the roughest surface while the
zinc oxide eugenol (Temrex) exhibited considerably more resistance and
the smoothest surface. Zinc phosphate showed the greatest resistance to
disintegration. Silico-phosphate cement exhibited the same behavior in
Class I restorations but showed higher failure in Class II restorations
due to fractures. Zinc phosphate exhibited smoother surface than the
silico-phosphate cement. There was no correlation between in vitro
solubility and clinical disintegration. Compressive strength seemed to
be related to the general durability of the materials.
