“…In general, the emergence times of children in the present sample tended to be later than those reported by Halikis 1 and Carr. 2 The delays in median times of emergence ranged from a few months for some teeth up to a year for the maxillary first and second premolars ( Table 2).…”

Background: Published standards for permanent tooth emergence in Australian children are 40 years old. The aim of this study was to present new data on the timing and sequence of permanent tooth emergence in a large sample of Australian children and to compare the findings with those of earlier studies. Methods: Records of a randomly selected sample of 8676 children, aged between 4 to 16 years, who had attended the clinics of the South Australian Dental Service were scanned optically and coded to provide the data for this study. A logistic regression analysis enabled median times of emergence, together with percentile ranges, to be calculated for each tooth, except third molars, in boys and girls. Comparisons were made between the sexes and with previously published values. The frequencies of occurrence of emergence polymorphisms for different tooth pairs were also computed. Results:The earliest teeth to emerge in both boys and girls were the central incisors and first molars, whereas the second premolars and molars and maxillary canines tended to be last to emerge. The mandibular teeth tended to precede the corresponding maxillary teeth in emergence in both sexes. Tooth emergence was advanced in girls compared with boys, averaging 4.5 months in the maxilla and 5.3 months in the mandible. In general, emergence times of children in the present sample were later than those reported previously for Australian children. The most common emergence polymorphism in the maxilla involved the canine and second premolar, whereas common polymorphisms in the mandible were noted for the central incisor and first molar, canine and first premolar, and the second premolar and second molar. Conclusions: Given that they have been collected relatively recently from a large sample of children, the new data reported in this paper can now be used as standards when assessing permanent tooth emergence of Australian children.

“…According to Carr (13) and Sato (5), tooth eruption can be divided into embryological tooth eruption and clinical eruption. Clinical tooth eruption is considered in this investigation, and refers to the appearance of some part of the tooth in question above the gingival surface.…”

“…SEX MS is generally more common in women than in men , and dental caries are more prevalent in women of all age groups than in men, according to national surveys in the United States of America (Kelly, 1974); Iceland (Dunbar et al, 1968); England (Gray et al, 1970); Scotland (Todd and Whitworth, 1974); Germany (Shirmer et al, 1975); and Polynesia (Beck and Ludwig, 1966). It has been suggested that very young girls have more caries than boys because of earlier tooth eruption in girls (Carr, 1962), but this does not explain the marked differences in caries between older women and men.…”

SUMMARY The geographical distribution and other epidemiological characteristics of multiple sclerosis (MS) are compared with those of dental caries. The rates of death due to MS in Australian states are linearly related to the numbers of decayed, missing, and filled (DMF) teeth found in individuals from those states (r = 0.97, P <0.002). In the United States of America, a strong positive correlation (r = 0.55, P <0.001) also exists between MS death rates and dental caries indices. The prevalence of MS in 45 countries or areas correlates well with the frequencies of DMF teeth among children of school age in those locations (r = 0.78, P <0.001). The prevalence of MS also correlates well with the percentage of edentulous individuals in certain countries (r = 0-99, P <0.001). A review of the literature shows that the risk for dental caries is lower among the following groups: the lower socioeconomic classes in the United States of America; Chinese immigrants to England compared with natives; blacks compared with whites; and males compared with females. The dental caries risk is higher during pregnancy and lactation. All these trends have been described for MS as well. It is suggested that dental caries may be a more accurate epidemiological model for MS than poliomyelitis. It is also suggested that MS and dental caries may share certain aetiological factors, two of which may be dietary excess of certain fats, and vitamin D deficiency.
