Australian longitudinal study of time and order of eruption of primary teeth.

Timing and sequence of eruption of primary teeth were studied longitudinally in 164 healthy Australian children. Eruption of primary teeth typically began between 7 and 8 months and was completed by 28 months. Tooth eruption was not significantly related to growth rate or to psychomotor maturity.

Australian aboriginal studies. 1. The effect of socio-economic changes on the prevalence of caries in 6-14 year-old children resident at Bathurst Island and Groote Eylandt in the Northern Territory of Australia, 1971.

Investigations carried out on 6--14 year-old Aboriginal children resident at Bathurst Island and Groote Eylandt showed that the Groote Eylandt children had a higher prevalence of dental caries at statistically significant levels. This difference in prevalence was attributed to the greater financial affluence at Groote Eylandt.

Groote Eylandt studies. 2. Fluoridation of a small domestic water supply, C.M.S. Angurugu mission, Groote Eylandt, N.T., Australia. 1973-1974.

A system is described for fluoridation of a small community water supply. The design of the equipment is presented in relation to the requirements of a particular isolated region and in a basis for application to other similar areas. The problems found during the establishment of this system and their solution can be valuable as a guide for other communities.

Fractionated cystography to assess infiltration of the bladder wall by intravesical tumors.

Twenty cases of carcinoma of the cervix uteri stage III and IV and ten cases of carcinoma of the rectosigmoid colon stage III were investigated by fractionated cystography to detect any infiltration of the destensible part of the urinary bladder wall. Cystography was normal in all cases except one. The finding was confirmed operatively in each of the ten cases of rectosigmoid carcinoma.
