Clinical Trial Summary

Clinical Trial Description

The experiment is based on earlier research where it was proven that chewing gum usage with anthocyanin rich sour cherry extract significantly reduces the amount of human salivary alpha-amylase in unstimulated saliva samples and stimulated saliva samples taken in every 5 minutes till a half an hour as compared to placebo. The investigators' study: Examination the effect of sour cherry anthocyanin containing chewing gum in a study taking a 3-week experimental period. At the beginning of experimental period oral and basic periodontal examination of the participants. Selection of healthy young adults (10 person) and adults (10 person), who has good oral hygiene, do not suffer from serious general disease and do not get respiratory infection treated with antibiotics in the past 2 months. Arranging saliva sampling on fixed appointments (between 12:00 and 14:00, 1st, 4th and 7th day of the week) through 3 weeks. On the 1. week, which is a control period taking of resting saliva samples and stimulated saliva samples from the participants. The stimulated saliva sampling is made after chewing of a gum without active ingredient. At the end of the control week a full mouth scaling is made and after it all of the participants get sour cherry containing chewing gums to chew 3x daily till 2 weeks, and the sampling occasions arranged on the same days as on the control week. After scaling 10 participant change their toothbrush, and 10 do not change. The saliva sample analyzation is placed in the Institute of Food Technology, the Department of Human Genetics and Department of Microbiology where they are frozen on -80 Celsius till the laboratory analysis. 16S (16 Svedberg) rRNA (ribosomal ribonucleic acid) sequencing is starting with DNA isolation by Inhibitor Removal Technology followed by sequencing with Illumina MiSeqSystem. PCR (Polymerase Chain Reaction) analysis of saliva samples starting with RNA isolation of samples with MagMAX Viral Kit, followed by RNA transcription and qPCR (quantitative polymerase chain reaction ) according to the Manufacturer's Instructions. ELISA (Enzyme Linked Immunosorbent Assay) analysis with appropriate saliva analyzation kit for the listed cytokines as follows: Examined cytokines (PCR and ELISA): Interleukins: Interleukin-1β, Interleukin-2, Interleukin-6; TNF(tumor necrosis factor) alfa, Melatonin (ELISA) , Mucin 7 (ELISA) and Mucin-5B (5subtypeB) (ELISA). The investigators' aims to are to extend the background of the earlier established phenomena: The sour cherry (anthocyanin) containing chewing gum usage (around 2 weeks, daily 3 times) is beneficent on the human oral microflora and cytokine level/expression. ;
