The prevalence of hypodontia was greater in permanent dentition than in primary dentition; although, it was not much different between males and females or between the right and left sides. The prevalence of dental anomalies was significantly different among four groups by cleft type: cleft lip, cleft lip and alveolus, cleft lip and palate, and cleft palate.

Single-particle states in Ca have been investigated through the Ca(d, p) 'Ca reaction with polarized deuterons of Eg --56 MeV. Angular distributions of differential cross sections and vector analyzing powers were measured for 91 transitions up to 9.7-MeV excitation energy by using a magnetic spectrograph. Analyses of these data were performed to determine j and t S of singleparticle levels with zero-range distorted-wave Born approximation calculations using the adiabatic approximation. The occupation probabilities and the single-particle energies in Ca were extracted for the valence (2p -1f) and (2s -1d) shells with including previous (p, d) data. The results on these quantities show good agreement with theoretical expectations.PACS number(s): 21.10. Jx, 21.60.Cs, 25.45.Hi, 27.40.+z
