[Dental caries in the support area and the therapeutic problem of the positioning of the canines and premolars in the dental arches].

The purpose of this study was to analyse the health of teeth in the buccal segments following space loss resulting from approximal caries of deciduous molars. The sum of the mesiodistal diameters of unerupted cuspids and bicuspids was predicated with the help of tables and calculated on the basis of correlation with the total width of the lower incisors. On average boys had 5.1 carious deciduous cuspids and molars as compared with 4.8 for girls. The results concluded that 60 to 70% of the cases of space loss resulting from carious lesions of approximal surfaces of deciduous molars occurred in the maxilla and 46 to 54% in the mandible, when factors including which jaw, side and sex were taken into account.
