The objective of this work is to prove that oral cavity fluids diffuse into alginate mass of impressions. In addition, the information is presented on the subject that disinfectants used for alginate impressions disinfection not only diffuse into alginate mass but penetrate deeper than oral cavity fluids.
Three examination groups were formed for the research, the results of which evidenced how deeply oral cavity fluids and disinfectants 'Alpha Guard GF' and 'Orbis' could possibly diffuse into alginate impression material 'Kromopan 100'. In the first examination group ten impressions from the upper jaw dental arch and mucosa were taken, firstly colouring oral cavity fluids with a special colouring tablet MIRA-2-TON (Hager Werken). Cuts were randomly selected from impressions and scanned aiming to establish the depth of the coloured oral cavity fluid penetration. In the second and the third examination groups taken alginate impressions were accordingly soaked in 'Alpha Guard GF' and 'Orbis' with pigment and later randomly selected cuts were scanned in the same manner as in the first research group. RESULTS. The research results establish that coloured dental cavity fluids maximum diffuse into alginate impression is up to 540 microm with the presence of 95% of discolouring while disinfectants 'Alpha Guard GF' and 'Orbis' accordingly diffuse into alginate mass up to 710 microm and 870 microm with the presence of 95% of discolouring. CONCLUSIONS. The results obtained show that disinfectants using them according to the recommendations of a manufacturer, diffuse into alginate mass deeper than oral cavity fluids at the time of impressions taking.
本研究的目的是证明口腔液体会扩散到藻酸盐印模材料中。此外，还提供了有关用于藻酸盐印模消毒的消毒剂的信息，这些消毒剂不仅会扩散到藻酸盐材料中，而且比口腔液体渗透得更深。
为该研究组建了三个检测组，其结果证明了口腔液体以及消毒剂“Alpha Guard GF”和“Orbis”可能扩散到藻酸盐印模材料“Kromopan 100”中的深度。在第一个检测组中，取自上颌牙弓和黏膜的十个印模，首先用特殊的染色片剂MIRA - 2 - TON（哈格 Werk公司）对口腔液体进行染色。从印模中随机选取切片并进行扫描，以确定染色的口腔液体渗透深度。在第二个和第三个检测组中，将取得的藻酸盐印模分别浸泡在含色素的“Alpha Guard GF”和“Orbis”中，之后以与第一个研究组相同的方式对随机选取的切片进行扫描。结果：研究结果表明，染色的口腔液体在藻酸盐印模中的最大扩散深度可达540微米，此时95%存在变色情况；而消毒剂“Alpha Guard GF”和“Orbis”在藻酸盐材料中的扩散深度分别可达710微米和870微米，此时95%存在变色情况。结论：所得结果表明，按照制造商的建议使用消毒剂时，在取印模时其在藻酸盐材料中的扩散深度比口腔液体更深。
