“…CAP eliminates remaining pathogens and alters the tooth surface. CAP treatment showed an increase in bonding strength in the dentin–adhesive interface [ 79 , 80 , 81 ] and enhanced enamel remineralization [ 82 , 83 ]. This may prevent secondary caries.…”

Interest in the application of cold atmospheric plasma (CAP) in the medical field has been increasing. Indications in dentistry are surface modifications and antimicrobial interventions. The antimicrobial effect of CAP is mainly attributed to the generation of reactive oxygen and reactive nitrogen species. The aim of this article is to systematically review the available evidence from in-vitro studies on the antimicrobial effect of CAP on dental pathogens. A database search was performed (PubMed, Embase, Scopus). Data concerning the device parameters, experimental set-ups and microbial cultivation were extracted. The quality of the studies was evaluated using a newly designed assessment tool. 55 studies were included (quality score 31–92%). The reduction factors varied strongly among the publications although clusters could be identified between groups of set pathogen, working gases, and treatment time intervals. A time-dependent increase of the antimicrobial effect was observed throughout the studies. CAP may be a promising alternative for antimicrobial treatment in a clinically feasible application time. The introduced standardized protocol is able to compare the outcome and quality of in-vitro studies. Further studies, including multi-species biofilm models, are needed to specify the application parameters of CAP before CAP should be tested in randomized clinical trials.

“…Prior to the erosive challenge, the specimens in the CAP groups underwent treatment with a plasma jet (Medaion, Nik Fanavaran Plasma Co., Tehran, Iran) using helium gas at a flow rate of 2 L/min with a potential difference of 4 kV, and 20 kHz frequency such that the nozzle tip had a maximum distance of 10 mm from the tooth surface [ 21 ] ( Figure 1 ). Next, the specimens were subjected to different fluoride varnishes according to their experimental groups.…”

“…In recent years, cold atmospheric plasma (CAP) has been used for root canal sterilization, enhancement of bond strength, and tooth bleaching [ 18 – 20 ]. Kim et al [ 21 ] showed that helium CAP prior to varnish application enhanced the uptake of fluoride ions by the enamel surface. Moreover, evidence shows that the effects of CAP treatment in combination with fluoride last for a longer period of time compared with the effects of fluoride alone.…”

Purpose. Considering the suggested advantages of cold atmospheric plasma (CAP) in increasing the fluoride uptake by the enamel, this study aimed to assess enamel erosion following the application of helium CAP and two types of fluoride varnishes. Methods. The microhardness of 70 bovine enamel specimens was measured using a Vickers hardness tester. The specimens were randomly divided into 7 groups (n = 10): control, CAP (P), resin-containing fluoride varnish (RF), CAP + resin-containing fluoride varnish (PRF), fluoride varnish (F), CAP + fluoride varnish (PF), and erosion (E). The specimens in the control and erosion groups did not receive CAP or fluoride varnish. All specimens underwent erosive challenge 4 times/day using hydrochloric acid and artificial saliva except for the control specimens that remained in distilled water during the course of the study. After 5 days of erosive challenge, microhardness was measured again, and the percentage of microhardness change was calculated. Surface roughness of two specimens in each group was assessed by atomic force microscopy (AFM). Data were analyzed using one-way ANOVA followed by Tamhane’s post-hoc test. Results. The percentage of microhardness change in all groups was significantly higher than that of the control group. All groups showed significantly lower percentage of microhardness change compared with the E group except for the P group; no significant difference was noted in microhardness change of P and E groups. Other experimental groups had no significant difference with each other. Surface roughness was the highest in PRF and the lowest in the F group. Conclusion. CAP application had no significant effect on increasing the enamel resistance to erosion. However, enamel resistance to erosion increased significantly after fluoride varnish application alone or fluoride varnish application combined with CAP. No significant difference was noted between the two types of varnishes in this regard. CAP increased the surface roughness while fluoride varnish application alone decreased the roughness.

“…So uoride application can produce a large amount of calcium uoride and uorapatite when hydroxyapatite of tooth is treated with plasma. In our previous study, as for the resistance to demineralization, the calcium-to-phosphate ratio of the enamel treated with APF and nonthermal atmospheric plasma was higher than that treated with APF alone, and it increased with the frequency of treatment [30]. So the combination treatment of nonthermal atmospheric plasma and uoride improves retention of uoride on the enamel and resistance to demineralization when compared with treatment with uoride alone.…”

Background: Low temperature atmospheric plasma has been studied in biomedical fields but the fluoride application effect of plasma on deciduous teeth has not been studied. This study examined the fluoride application effect of plasma devices (low frequency helium and microwave argon plasma) on the enamel surface of deciduous teeth.Methods: In the tooth specimens of the control group, only 1.23% acidulated phosphate fluoride (APF) gel was applied, whereas APF gel and plasma were applied to the specimens of the experiment group. The fluoride on the enamel surface was measured at different treatment times, and its retentivity was also observed over a 4 week period using an electron probe micro analyzer, which is a strong detector of fluoride. The study protocol was reviewed by the Institutional Review Board (IRB; PNUDH-2014-026) of Pusan National University Hospital.Results: More fluoride was measured and maintained in the experiment group than the control group, and the amount of coated fluoride increased with increasing applied frequency. A comparison of two types of plasma revealed the microwave argon plasma to have a higher application effect of fluoride than the low frequency helium plasma. This study suggests that fluoride application using plasma could be an effective and lasts longer than the method of applying only fluoride. Conclusion: The fluoride application with low temperature atmospheric plasma which is safe device is an innovative method to prevent dental caries and decrease number of visiting to dental clinic in children.
