“…In the neighborhood of Zemunik there are deposits of Al ore, so we were first of all interested in this trace element, and also in Sr, as this element has often been men tioned lately as being possibly associated with low caries prevalence or low decay rate [Lodrop, 1953;Losee and Adkins, 1968;Barmes, 1969;Little and Barrett, 1976a, b;Curzon et al, 1970Curzon et al, ,1977,…”

The concentration of aluminium and strontium was determined (by AAS) in soil (total and exchangeable), drinking water and dental enamel from an area (Zemunik) with low caries prevalence (DMFT < 2). For comparison purposes, similar samples were collected and analyzed from another village (Novigrad) in the same region with normal caries prevalence (DMFT > 5). A positive correlation between low caries prevalence and a higher concentration of strontium in soil (exchangeable form), drinking water and enamel was found. The distribution of strontium in dental enamel was shown to be fairly uniform. The concentration of aluminium in drinking water and the exchangeable form in soil was higher in the area of Zemunik.

“…Zinc readily substitutes for calcium in hydroxyapatite and confers greater resistance to acid dissolution [52][53][54][55][56][57]. Moreover, where Zn is present at concentrations >107 ppm, and at low pH (~4.0), it is actively involved in a dissolution/reprecipitation reaction where a new mineral phase ($-hopeite, $-Zn 3 (PO 4 ) 2 .H 2 O) forms on the hydroxyapatite lattice surface, so blocking further demineralisation [58].…”

Cementum and the incremental markings it contains have been widely studied as a means of ageing animals and retrieving information about diet and nutrition. The distribution of trace elements in great ape and fossil hominin cementum has not been studied previously. Synchrotron X-ray fluorescence (SXRF) enables rapid scanning of large tissue areas with high resolution of elemental distributions. First, we used SXRF to map calcium, phosphorus, strontium and zinc distributions in great ape dentine and cementum. At higher resolution, we compared zinc and strontium distributions in cellular and acellular cementum in regions where clear incremental markings were expressed. We then mapped trace element distributions in fossil hominin dentine and cementum from the 1.55–1.65 million year old site of Koobi Fora, Kenya. Zinc, in particular, is a precise marker of cementum increments in great apes, and is retained in fossil hominin cementum, but does not correspond well with the more diffuse fluctuations observed in strontium distribution. Cementum is unusual among mineralized tissues in retaining so much zinc. This is known to reduce the acid solubility of hydroxyapatite and so may confer resistance to resorption by osteoclasts in the dynamic remodelling environment of the periodontal ligament and alveolar bone.

“…Furthermore, Curzon and Losee [1977a] were able to demonstrate that high [Sr] in enamel were associated with low caries prevalence by studying 147 samples obtained from 59 communities in 19 states in the USA. Other elements, such as F, were not studied.…”

Investigations into the role of strontium (Sr) in caries prevention have attracted great interest in the research community in the past, with its peak in the 1970-and 80ies. To this date, no clear indication of the relative importance of Sr in caries prevention has been provided. A vast number of animal caries, epidemiological and mechanistic studies have been conducted. Albeit Although a great level ofthere is much discrepancyexists in the literature, the majority of studies suggest that Sr exhibits some cariostatic properties and, predominantly in the presence of fluoride (F). An optimum Sr concentration of 5 to 10 ppm in drinking water has been proposed as a direct result of several epidemiological caries studies. Despite these results, no direct link can be established between Sr and caries prevention as, to date, no relevant, randomized control trials have been reported. The extrapolation of potential cariostatic properties of Sr from epidemiological studies is difficult due to the co-presence of several other trace elements in the water of the study areas, with many of these elements being attributed cariostatic properties in their own right.
