數種 窩洞裏裝材의 象牙質細管 廢鎖效果에 關한 實驗的 硏究 = AN EXPERIMENTAL STUDY ON THE SEALING EFFECT OF A FEW CAVITY LINERS UPON THE DENTINAL TUBULE.

다국어 초록 (Multilingual Abstract)

ABSTRACTThe sealing effect of a few cavity liners uoon the dentinal tubule were studied in vitro.
The materials employed in this study were Silcot (SPECIALITIES SEPTODONT, M.-T. GEN-
DRAULT, Pharmaden),Hypo-Cal(EUman Dental Mfg. Co. Inc.),CavityLining(De Trey), and Copaute
(Harry J. Bosworth Co.). Freshly extracted human teeth were devided into 5 groups by age-unaer
twenty, twenties, thirties, forties, and over fifty. Class V cavities were prepared routinely. The
cavity walls of eight teeth of each group were lined by Silcot, Copalite, Cavity Lining, and Hypo-
Cal. Remaining eight were not lined as a control. These specimens were immersed in dye solution
(2 gm eosin Y to 800 cc distilled water) for 48 hours to allow maximum dye penetration into
dentinal tubules. Each specimen was sectioned longitudinally including Class V cavity floor under
water spray. Dye penetration into dentinal tubules were examined and following results were
obtained.

1. Liners used on this study showed more or less dye penetration into dentinal tubules. But com-
pared with the teeth without lining, the dye penetration of lined specimens were decreased.

2. Of these liners tested, Silcot was the most effective sealer upon the dentinal tubules. Copalite
was the moderate sealer and Cavity Lining showed a tendency similar to Copalite. Hypo-Cal
revealed the greatest dye penetration.

3. As the age was increased, the more the dye penetration into the dentinal tubules was decreased.
