Summary

This study analyzed inorganic content in snuff, finding significant levels of insoluble elements. High inorganic material may increase the risk of dental abrasion when snuff is used like chewing tobacco.

Area of Science:

Oral Health
Materials Science
Analytical Chemistry

Background:

Snuff contains inorganic materials, but their composition and properties are not fully characterized.
Understanding snuff's inorganic content is crucial for assessing potential oral health risks.

Purpose of the Study:

To determine and quantify the inorganic constituents of four snuff brands.
To investigate the physical and chemical properties of these inorganic materials.

Main Methods:

Visual inspection, Scanning Electron Microscopy with Energy Dispersive X-ray (EDX) analysis, and light emission spectrography were employed.
Inorganic content was quantified by burning dried snuff to a constant weight.

Main Results:

Snuff contained large, yellow, water-insoluble, crystal-like particles rich in various elements (Ag, Al, Ba, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, P, Pb, Si, Sr, Ti, Va, Zr).
The total inorganic material ranged from 12.35% to 20.95% by weight.
Snuff ashes were an amorphous mass, lacking the distinct crystalline particles found in wet snuff.

Conclusions:

Snuff possesses a high percentage of inorganic material, including insoluble elements.
The presence of abrasive inorganic particles suggests a potential risk for dental and restoration abrasion if snuff is used orally, similar to chewing tobacco.
