초록

The purpose of this study was to compare the smoothness of enamel surfaces produced by two different reproximation
methods : fine diamond bur and fine metal strip. Natural enamel surfaces, enamel surfaces stripped with
fine diamond bur (20μm), and enamel surfaces stripped with metal strip (Dentarum) were evaluated with the profilermeter
and a scanning electron microscope (SEM). Four subjects who had at least three bicuspid extractions were
selected for this study and their bicuspid enamel surfaces were divided into three groups. : Group I : natural enamel
surface. Group II : enamel surface stripped with a fine diamond bur. Group III : enamel surface stripped with a
metal strip(Dentarum). The results were as follows. 1. According to the profilemeter roughness test, a comparison
between groups I and II and a comparison between groups I and III showed statistic significance, while a comparison
between groups II and III did showed no statistic significance. 2. SEM photographs of the natural enamel surface
showed individual variation in the pattern of enamel surface. Subsequent stripping with a fine diamond bur in vitro
resulted in small, smooth and regular furrows. Subsequent stripping with metal strip in vitro produced wide and
irregular furrows. 3. A plaque index test in vivo revealed that the sample with roughened natural enamel surface
had higher plaque accumulation with a broader disclosing area compared to the surfaces of groups II and III. Even
though there were differences in the pattern of enamel surface between groups II and III, the roughnness of enamel
surfaces for group II was similar to that of group III. In the case of a enamel surface with large furrows, subsequent
stripping of the enamel surface with a fine diamond bur or a fine metal strip decreased plaque retention.
