Streszczenie

Wprowadzenie. W zapobieganiu próchnicy zębów powszechnie są stosowane pasty do zębów zawierające do 1500 ppm fluoru, u osób z wysokim ryzykiem próchnicy zalecanie są natomiast pasty z wysoką zawartością fluoru.
Cel pracy. Ocena retencji fluoru w ślinie po jednorazowym szczotkowaniu zębów pastą z wysoką i standardową zawartością fluoru.
Materiał i metody. Badaniem objęto 59 osób w wieku 21–24 lat. Ochotnicy uczestniczący w badaniu szczotkowali zęby pastą Duraphat® 5000, grupa A (n = 30) lub pastą Pro Gum Health®, grupa B (n = 24) w tej samej ilości (długość pasma pasty 1 cm) przez 1 minutę i po zakończeniu nie płukali jamy ustnej wodą. Obydwie pasty zawierają fluorek sodu, pasta Duraphat w ilości 5000 ppm, a pasta Pro Gum Health® 1450 ppm. Stężenie fluoru w ślinie za pomocą jonowoselektywnej elektrody oznaczano 5-krotnie przed szczotkowaniem (badanie 0) i po upływie 15, 30, 60 i 120 min od zakończenia szczotkowania (badanie 1–4).
Wyniki. W grupie A wyjściowo (badanie 0) średnie stężenie fluoru w ślinie wynosiło 0,18 ± 0,12 ppm, a w grupie B 0,15 ± 0,13 ppm. Po upływie 15 min od szczotkowania (badanie 1) wzrastało w grupie A ok. 32-krotnie do wartości 5,73 ± 3,91 ppm, natomiast w grupie B ok. 11-krotnie do wartości 1,59 ± 1,24 ppm. Po upływie kolejnych 15 min (badanie 2) wartości wynosiły odpowiednio 1,92 ± 1,24 ppm i 0,53 ± 0,44 ppm, ujawniając odpowiednio ok. 11-krotny i 3,5-krotny wzrost w odniesieniu do badania 0. W badaniu 3 po upływie 60 min stwierdzono zmniejszenie retencji fluoru, w grupie A do wartości 0,47 ± 0,44 ppm, 3-krotnie wyższej od wartości wyjściowej, a w grupie B jedynie nieznacznie większe stężenie średnio o 0,01 ppm. Po upływie 120 min od szczotkowania (badanie 4) w obu grupach zaobserwowano nieco mniejsze od wyjściowego stężenie fluoru w ślinie.
Wnioski. Schemat retencji fluoru w ślinie w funkcji czasu po użyciu obu past był podobny. Użycie pasty z wysoką zawartością fluoru w porównaniu z pastą o konwencjonalnej zawartości fluoru powodowało istotnie wyższy wzrost stężenia fluoru w ślinie utrzymujący się przez dłuższy czas.

Abstract

Background. Fluoridated toothpastes containing up to 1500 ppm of fluoride have been commonly used in caries prevention, however, for subjects with high risk of developing caries toothpastes with high content of fluoride are recommended.
Objectives. Evaluation of fluoride retention in saliva after single toothbrushing with the use of toothpaste containing high and standard content of fluoride.
Material and Methods. The study comprised 59 subjects aged 21–24 years. The examined subjects, volunteers, brushed their teeth with the Duraphat® 5000 toothpaste – group A (n = 30) or with the Pro Gum Health® toothpaste – group B (n = 24). Both groups used the same amount of paste (stripe length 1 cm) for 1 min and after completed toothbrushing they did not rinse the oral cavity with water. Both toothpastes contain natrium fluoride, the Duraphat® paste 5000 ppm F, and the Pro Gum Health® paste 1450 ppm F. The level of fluoride in saliva was assessed by ionoselective electrode 5 times before toothbrushing (study 0) and after 15, 30, 60 and 120 min after toothbrushing (study 1–4).
Results. At the baseline the mean content of salivary fluoride in group A was 0.18 ± 0.12 ppm and in group B 0.15 ± 0.13 ppm. The level of fluoride increased after 15 min of toothbrushing, in group A 32-times, reaching approximately 5.73 ± 3.91 ppm, and in group B 11-times up to 1.59 ± 1.24 ppm from the baseline (study 1). After next 15 min (study 2), the mean amounted to 1.92 ± 1.24 ppm and 0.53 ± 0.45 ppm revealing ca. 11-times and 2.5-times increase in comparison to study 0, respectively. In study 3, after 60 min, the reduction of the fluoride retention was found, in group A to the mean value of 0.47 ± 0.44 ppm, 3-times higher, and in group B only slightly higher level ca. 0.01 ppm. 120 min after toothbrushing (study 4) a slightly lower level of salivary fluoride was observed in both groups.
Conclusion. The pattern of fluoride retention in saliva in time after toothbrushing with fluoridated toothpastes was similar. Significantly higher increase of salivary fluoride was caused by the toothpaste with high concentration of fluoride in comparison to the toothpaste with conventional content of fluoride, which persisted for a longer period of time in saliva.
