Abstract [sv]

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

Abstract [en]

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 (approximate to 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.
