Salivary calcium concentration and periodontal health of young adults in relation to tobacco smoking.

Purpose: To evaluate the effect of tobacco smoking and salivary calcium on the periodontal status of young adults.

Materials And Methods: Plaque index, gingival bleeding on probing, supragingival calculus, DMFT index, salivary flow, pH and salivary calcium in unstimulated salivary samples were recorded in smokers and nonsmokers.

Results: There were no significant differences between smokers and nonsmokers with respect to salivary flow (P = 0.

Tin content determination in canned fruits and vegetables by hydride generation inductively coupled plasma optical emission spectrometry.

Tin content in samples of canned fruits and vegetables was determined by hydride generation inductively coupled plasma atomic emission spectrometry (HG-ICP-OES), and it was compared with results obtained by standard method of flame atomic absorption spectrometry (AAS). Selected tin emission lines intensity was measured in prepared samples after addition of tartaric acid and followed by hydride generation with sodium borohydride solution. The most favorable line at 189.
