Kerr sealer를 根管充塡材로 使用時 根管閉鎖性에 關한 實驗的 硏究 = EXPERIMENTAL STUDY on SEALING QUALITY OF KERR SEALER AS ROOT CANAL SEALERS.

다국어 초록 (Multilingual Abstract)

AbstractThe author has studied comparatively the sealing quality of conventional Z.O.E. cement, Kerr sealer
and Nogenol sealer by means of penetration of 2% methylene blue solution through the root apex of
human teeth in 72 cases as time elapsed.The results were as follows;

1. All the specimens, whose dye immersion time is two days, showed dye penetration of low degree
unrelated to the kinds of root canal sealer.

2. Kerr sealer group, like conventional Z.O.E. group, showed dye penetration of high degree related
to increased time of immersion in the dye.

3. In Nogenol group, there was slight increase in penetration related to increased time of immersion
in the dye.

4. Kerr sealer group showed comparatively lower grade of dye penetration than conventional Z.O.E.
and higher than Nogenet sealer.
