    Purpose The boron and fluoride mainly accumulate in the bones and teeth of the human body. The purpose of this study is to determine boron or fluoride levels in the whole tooth, to evaluate the correlation between their levels and to compare these levels in primary/permanent, carious, and non-carious groups. Materials and Methods The boron and fluoride levels of thirty-six teeth, separated such as primary carious (n=9) and non-carious (n=9), permanent carious (n=9) and non-carious (n=9), were determined by ICP-MS and ion-selective electrode, respectively. Results While boron levels were between 0.001 and 5.88 ppm, the fluoride levels were between 21.24 and 449.22 ppm. The boron level of non- carious teeth was higher than those of carious teeth in primary and permanent tooth groups. However, this difference was not statistically significant (p>0.05). The fluoride level of non-carious teeth was higher than those of carious teeth in primary (p=0.062) and permanent teeth groups (p=0.046). Negative correlation, found between boron and fluoride in all groups, was significant only in non-carious teeth group (r=-0.488, p=0.040). Conclusion The results of our study proved the importance of fluoride as a protective factor for dental caries once more. The boron levels in non- carious teeth were also higher than carious teeth. However, it was not significant. Moreover, there was negative correlation between teeth boron and fluoride levels. Therefore, it is necessary to conduct more detailed studies on the tooth boron level and its relation with caries formation and with fluoride levels.

    Evaluating boron levels in Turkish mineral waters: a comparative study of three analytical techniques

    Turkey is abundant in natural mineral water sources, thanks to its location on the Alpine-Himalayan belt. Natural mineral water is drinking water characterized by its natural mineral, trace elements, and carbon dioxide content. Because of quite insufficient data, the boron content in bottled natural mineral waters in Turkey was analyzed by three different methods and compared: inductively coupled plasma mass spectrometry technique, carminic acid, and azomethine-H methods, in this study. The boron levels in mineral waters ranged from a minimum of 0.05 mg/L to a maximum of 8.61 mg/L. It was also safe by the upper limit level estimated by the World Health Organisation. As boron plays a beneficial role in human physiology, consuming natural mineral water may offer a positive contribution to public health by supporting boron intake in our country. The other outcome of our research was that the spectrophotometric carminic acid method can yield results similar to those obtained using the inductively coupled plasma mass spectrometry technique since the boron level of Turkish mineral water was within the limits level of the carminic acid method. However, the result of the azomethine-H method was found not to be suitable. Cross-sensitivity with other elements in mineral water might have caused this.
