- The aim of this study was to investigate the effects of the Swedish moist powder tobacco product known as "snus" on dental caries and to measure the pH fall in dental plaque. The subjects comprised male and female adults between 26 and 62 years of age (n=102), all habitual snus users for >= 10 years. The control group (n=101) consisted of similar individuals in terms of gender, age and educational level but with no tobacco use for >= 10 years. A clinical and radiographic examination and a questionnaire were completed.The pH fall after a sucrose rinse was estimated in situ in 10 randomly selected subjects per group. The salivary secretion rate was higher in snus users than non-users (2.5 vs 2.2 ml/min, p=0.005). There was no statistically significant difference regarding salivary buffer capacity. No differences were found between the two groups in terms of the plaque index, primary or secondary enamel and dentine caries, DFS and salivary counts of mutans streptococci or lactobacilli. The pH fall was somewhat more pronounced among non-users compared with snus users (NS). Snus users had a lower intake of snacks between meals and a less frequent intake of cookies (p=0.000). Furthermore, snus users had a mean gingival index (+/- SD) for the whole dentition of 20.4 +/- 18.2, while the index for non-users was14.4 +/- 13.9 (p=0.009); the corresponding values for teeth 13-23 were 14.9 +/- 20.6 and 7.7 +/- 11.9 respectively (p=0.003). To conclude, this clinical study revealed no statistically significant differences in caries prevalence between snus users and non-users and only minor differences regarding different cariesassociated factors.

- Syftet med studien var att utvärdera pH-förändringar i plack in vivo vid användning av olika nikotinfritt och nikotinhaltigt snus. Kolhydratinnehållet i produkterna analyserades också. Tio deltagare, alla snusanvändare, deltog i en experimentell tvärsnittsstudie, vid elva tillfällen, med en veckas mellanrum. Sex nikotinfria och fyra nikotininnehållande produkter på den svenska marknaden ingick i studien och en sackaroslösning användes som kontroll. Deltagarna borstade inte tänderna under tre dagar innan besöket och avstod från att äta, dricka och snusa/röka två timmar före varje test. pH mättes i tre approximalrum upp till 45 minuter med snusprodukten placerad under överläppen. De nikotininnehållande produkterna innehöll endast spår av glukos, fruktos och sackaros (0.5-1%) och stärkelse (1.5%), medan de nikotinfria produkterna innehöll upp till 6.5 % lågmolekylära kolhydrater och 26.0 % stärkelse. Resultatet av pH-mätningarna i plack visade att alla fyra nikotininnehållande produkter höjde pH, till skillnad från tre av de sex nikotinfria produkterna, som sänkte pH betydligt. Dessa pH-förändringar i plack kan ha såväl positiv som negativ effekt på kariesrisken beroende på vilken produkt som används

Effect of nicotine-free and nicotine-containing snus on plaque pH in vivo

- The aim was to investigate pH changes in plaque in vivo during the use of nicotine- free and nicotine-containing snus. The carbohydrate content of the products was also analysed. Ten subjects, all regular snus users, participated in an experimental cross-over study, on eleven occasions with an interval of one week. Six nicotine-free and four nicotine-containing products, which are sold on the Swedish market, were included and a sucrose solution was used as a control. The subjects did not brush their teeth for three days before coming to the laboratory, without eating, drinking or using snus/smoking for two hours prior to the test. pH was measured at three approximal sites up to 45 min with the test product placed under the upper lip. The carbohydrate analysis showed that the nicotine-containing products contained only traces of glucose, fructose and sucrose (0.5-1%) and starch (1.5%). Some of the nicotine-free products contained up to 6.5% low-molecular-weight carbohydrates and 26.0% starch. The intraoral pH measurements showed that four nicotine-containing products increased the plaque pH, in contrast to three of the six nicotine-free products, which lowered the pH. These pH changes may have an effect on the caries risk, both positively and negatively, depending on which product is used.

Changes in tobacco habits : a prospective longitudinal study of tobacco habits among boys who play ice hockey

Tidskriftsartikel (refereegranskat)abstract
- The aim of the investigation was to follow up tobacco habits and actual sporting activities among the boys who participated in an earlier study by the authors, and to examine whether knowledge of the harmful effects of tobacco and tobacco behaviour patterns and/or the choice of tobacco had changed amongst the participants. The study was conducted 3 years after the original study. Data were collected using a questionnaire. Of the 183 boys in the age group 15-22 years who participated in the study, 26.8% were tobacco users: 19.7% only snuff users, 6.0% both snuff users and smokers and 1.1% smokers. Compared with the original study, a further 16.4% of the boys had started to use tobacco. The use of tobacco increased in all age groups except amongst 19-year-olds where tobacco use was unchanged. The age group 17-22 years included boys who were both snuff users and smokers. An increase in tobacco use between the ages of 17 and 19 years could be shown compared with the original study, for equivalent age groups. Among the 132 boys who still played ice hockey, 25.8% were tobacco users: 18.2% only snuff users, 6.1% both snuff users and smokers and 1.5% smokers. A statistically significant difference (p < 0.05) could be shown between boys who used snuff and non-users depending on whether the boys participated in another sport besides ice hockey. Snuff usage was thus not as widespread among boys who participated in other sporting activities. The increase in tobacco use amongst the boys in the study showed that the various preventive initiatives which society so far has offered have been inadequate. Hence, the preventive measures need to be evaluated and developed to prevent tobacco habits from becoming established. The results of this and previous studies show that the environment in which ice hockey is practiced can, in itself, constitute a risk for tobacco usage becoming established among ice-hockey-playing adolescents

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present investigation was to study differences in background factors between ice-hockey-playing boys who used snuff, who had tried using snuff, and who had never used snuff. The background factors studied were the socio-economic conditions of the boys' parents; the tobacco habits of the boys' parents, siblings, and friends; the boys' choice of theoretical or practical upper secondary school programme; knowledge of the harmful effects of tobacco as well as participation in a sport other than ice hockey. Data were collected usinG a questionnaire. Of 249 boys in the age group 12-19 years who participated in the study, 13% used snuff, 34% had tried using snuff, and 53% had never used snuff. The factors knowledge of the harmful effects of tobacco and choice of theoretical or practical upper secondary school programme had no significant association with the boys' snuffing habits. This was also true for the parents' tobacco habits unless their habits were analysed separate from each other, where "mother smoked" showed an association with boys who used snuff. The study also showed a significant difference between boys who used snuff and boys who had never used snuff and between boys who had tried using snuff and boys who had never used snuff; boys who used snuff tended to have siblings who used snuff. Of boys who used snuff, 77% reported that their friends' use of snuff had influenced them to start using snuff. A significant difference could also be shown between boys who used snuff, had tried using snuff and never-users depending on whether the boys participated in a sport other than ice hockey. Snuff usage was not as widespread among boys who participated in other sport activities. This was verified by the multivariate logistic regression analysis where "taking part in other sports than ice hockey" was the explanatory variable that showed the strongest association with the dependent variable. An active participation in ice hockey and the environment, in which this sport is practised, would consequently be a strong influencing factor to start using snuff.

Ingår i: Swedish Dental Journal. ; 24:1-2, s. 59-70
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate tobacco habits among ice-hockey-playing boys in three clubs in the County of Värmland, Sweden and to analyse whether health information about the harmful effects of tobacco could change the players' tobacco habits. In addition, the issue of whether there is any correlation between knowledge of tobacco and its harmful effects with tobacco habits was studied. Ice-hockey-players from three ice-hockey clubs were represented and one of the clubs acted as a control group. A total of 252 male ice-hockey-players, 12-19 years old participated. A specially designed questionnaire containing 33 questions on background, socioeconomics, behaviour, and knowledge was used. The boys answered the questionnaire on three occasions. The first and second examinations took place on the same occasion with the intervention occurring between the examinations. The third examination was carried out after 3-5 weeks. The study showed that the use of snuff played a more important role among the ice-hockey-players than did smoking and that they had tried using snuff at the age of 12. The baseline investigation showed that there were no significant differences between the clubs in tobacco habits and knowledge of the harmful effects of tobacco. After the health information, the boys' knowledge of tobacco and its harmful effects increased significantly (p<0.001), but regardless, no change in their use of tobacco was found after 3-5 weeks. Knowledge also increased significantly among the boys in the control group (p<0.001), but no change in the use of tobacco was found here either. No significant difference could be demonstrated between the group of boys who used snuff and the non-users with regard to their knowledge of the harmful effects of tobacco.
