Abstract
The proximal surfaces of deciduous teeth with C2 were restored with Fuji II LC. Twenty cases were then, given polishing on the same day and another twenty cases one day after, while observation of these cases was made clinically for one year.
The results were as follows:
1. With regard to marginal adaption, the cases with polishing one day after showed some what better progress than the cases with polishing on the same day.
2. Marginal discoloration showed about the same tendency as the degree of marginal adaptation.
3. The refractory adrasiveness and color tone of the restoration showed good progress without regard to the time for polishing.
4. As to pulp reaction, the cases with polishing on the same day showed an increase in symptoms of dysphoria six months after restoration, and cases requiring pulp treatment were also found.
5. As for the occurrence of secondary caries, the cases with polishing one day after showed better progress than the cases with polishing on the same day. On the basis of the foregoing findings, restoration of the proximal surfaces of the deciduous anterior teeth with glass ionomer cement of the light-cured type for polishing produced better results when polishing was done one day after restoration than with polishing immediately after.
Further and extended investigations are necessary, for deciduous molars as well.
