Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.

In the treatment of impacted third molar, dental practioner and oral surgeon more often think about how to extract the third molar completely, but rarely consider to add some procedures such as distal wedge, alveoloplasty, guided tissue regeneration, and apically repositioned flap etc., to prevent 2nd molar from developing periodontitis. The latter procedures can reduce its accompanying deep pocket, to remove plaque and calculus on its diseased root surface.
