Graft LCII was used for restoration of the proximal cavities of 30 deciduous anterior teeth and of 25 immature permanent anterior teeth having C/ and the course was observed clinically.
The results were as follows:
1. Poor marginal adaptation after one year was found in 2 cases (3.3%) of the deciduous anterior teeth and in 5 cases (10.0%) of the immature permanent anterior teeth.
2. After one year, no morphological changes were found in 28 cases (93.3%) of the diciduous teeth and in 22 cases (88.0%) of the immature permanent teeth.
3. Scarcely any Staining/discoloration of the restorative dental materials was found. Staining/discoloration was found in 2 cases each of the deciduous teeth and the immature permanent teeth.
4. Absolutely no marginal discoloration was found in 27 cases (90.0%) of the deciduous teeth and in 24 cases (96.0%) of the immature permanent teeth.
5. Secondary caries was found 3 months after restoration in 1 cases each of the deciduous teeth and the immature permanent teeth, and in an additional case of the immature permanent teeth in the first year.
6. No pulp reaction at the time of restoration was found in nearly all cases. One case (3.3%) of the deciduous teeth required pulpal procedure.
7. No abnormaly at all in pulp reaction at recall after one year was found in 26cases (86.7%) of the deciduous teeth and in 23 cases (92.0%) of the immature permanent teeth.
8. On the basis of the foregoing findings, Graft LCII has been suggested to be effective for restoration of deciduous teeth and immature permanent teeth in everyday clinical work of pedodontics.
