Effect of Smoking Intensity on Whole and Minor Saliva Secretions
Objectives: Our aim was to investigate the possible effects of smoking intensity on salivary parameters (whole saliva and minor salivary gland flow rates) among smoker and non-smoker male and female patients in different age groups in Hungary.
Methods: 901 patients (age range:18-92 years, 58.3% females) were involved in the study, and were categorized into non-smoker (NS), light smoker (LS, 1-10 cigarettes per day – CPD), and moderate or heavy smoker (MHS, more than 11 CPD) groups according to self-report. Unstimulated whole saliva flow rate (u-SFR) was measured by the spitting method, while palatal (PS) and labial (LS) minor salivary gland flow rates were measured using the Periotron method. Data were analyzed using independent samples t-test, and one-way ANOVA at a significance level of p<0.05.
Results: 35.9% of our sample were smokers (43.4% of males and 30.5% of females). Regarding smoking intensity, 51.3% of females and 60.7% of males were MHS. u-SFR values of NS, LS and MHS females were 0.39±0.30 ml/min, 0.4±0.29 ml/min, and 0.39±0.28 ml/min, respectively, while for NS, LS and MHS males were 0.52±0.4 ml/min, 0.60±0.36 ml/min, and 0.56±0.37 ml/min, respectively. A significantly lower u-SFR was measured for MHS females (0.29±0.21 ml/min) compared to NS females (0.50±0.30 m/min) in the age group of 20-29 years (p=0.02). Among MHS males in the age group of 30-39 years, a significantly higher palatal secretion (3.83±2.42 µl/cm2/min) was registered compared to NS (1.42±0.21 µl/cm2/min) and LS groups (1.33±0.95 µl/cm2/min), respectively (p=0.03). No other significant differences have been recorded in the salivary parameters of NS, LS and MHS males and females in other age groups.
Conclusions: According to our results, higher intensity of smoking may decrease whole saliva secretion among females in younger age groups, however, we could not detected any effect of smoking intensity on minor salivary gland secretions in other age groups.
