Previous reports in the literature indicate that smoking is associated with increased plaque accumulation and/or mineralization. This might be due to an effect of tobacco smoke on properties of saliva. The present study examined the stability of components in fresh and incubated saliva in smokers and non‐smokers. Saliva from smokers, collected immediately after smoking a cigarette, did not differ significantly from that of non‐smokers in the turbidity developing after incubation (24 h, 37°C), which may reflect aggregation of salivary components by mechanisms analogous to those involved in plaque formation. This finding is in agreement with our previous result (Macgregor. Edgar & Greenwood 1985) which showed that the rate of plaque formation did not differ between smokers and non‐smokers. Although an intimation of higher initial calcium concentrations, greater precipitation of calcium and development of more turbidity during incubation was observed in the salivas of smokers than those of non‐smokers, the major reason for the greater plaque accumulation and calculus in smokers is probably inadequate oral hygiene.
