Förändringar i salivsekretionens hastighet och sammansättning under behandling med fast tandställning bland ungdomar - En longitudinell studie (Swedish)
Abstract [en]

Aim: To investigate unstimulated salivary secretion rate as well as total protein concentration in whole saliva and the concentration of MUC5B, sialic acid, IgA and histatin in whole saliva from adolescents during treatment with fixed orthodontic appliances. 

Method: Unstimulated saliva was collected prior to the study from 13 patients at four time points; I before onset of treatment, II-III during treatment and IV after treatment and the removal of fixed orthodontic appliances. The samples were stored at -80°C. Total protein concentration was analysed with the 2-D Quant Kit procedure, MUC5B, IgA and histatin with ELISA (Enzyme Linked ImmunoSorbent Assay), and sialic acid by the use of two lectins (MAA and SNA) with ELLA (Enzyme-Linked Lectin Assay).

Results: MUC5B (p = 0.048 ± 0.13), histatin (p = 0.045 ± 0.40), total protein concentration (p = 0.012), and MAA (p = 0.039 ± 0.11)(p = 0.030 ± 0.11) increased significantly during the treatment. Salivary secretion rate, IgA, and SNA did not show a significant change. 

Conclusion: The results suggest that total salivary protein concentration as well as MUC5B, histatin, and sialic acid increase during treatment with fixed orthodontic appliances. The changes in salivary composition are possibly related to the increase in oral mucosal abrasion and likely influenced by increased biofilm retention and thus increased biofilm maturation. A more comprehensive study providing a larger sample size, a control group, more frequent time points for sampling, and consideration of hormonal changes is needed to draw more precise and confident conclusions.

Abstract [sv]

Syfte: Att undersöka ostimulerad salivsekretionshastighet och total proteinkoncentration i helsaliv samt koncentrationen av MUC5B, sialinsyra, IgA och histatin i helsaliv bland ungdomar under behandling med fast tandställning. 

Metod: Ostimulerad helsaliv samlades in före studien från 13 patienter vid fyra tidpunkter; I före behandlingsstart, II-III under behandling och IV efter behandling och avlägsnande av tandställning. Proverna förvarades vid -80°C. Den totala proteinkoncentrationen analyserades med 2-D Quant Kit-proceduren, MUC5B, IgA och histatin med ELISA (Enzyme Linked ImmunoSorbent Assay) och sialinsyra med hjälp av två lektiner (MAA och SNA) med ELLA (Enzyme-Linked Lectin Assay).

Resultat: MUC5B(p = 0.048 ± 0.13), histatin(p = 0.045 ± 0.40), total proteinkoncentration(p = 0.012) och MAA(p = 0.039 ± 0.11)(p = 0.030 ± 0.11) ökade signifikant under behandlingen. Salivsekretionshastighet, IgA och SNA visade ingen signifikant förändring under loppet av behandlingen. 

Slutsats: Resultaten tyder på att den totala salivproteinkoncentrationen samt MUC5B, histatin och sialinsyra ökar under behandling med fast tandställning. Förändringarna i salivsammansättningen är möjligen relaterade till det ökade slitaget av munslemhinnan och påverkas troligen dessutom av en ökad biofilmsretention och därmed ökad mognad av biofilmen. En mer omfattande studie med en större testgrupp samt en kontrollgrupp, mer frekventa tidpunkter för provtagning och hänsynstagande till hormonella förändringar behövs för att dra mer exakta och säkra slutsatser.
