“…These results may be due to surface and bulk deterioration as a result of adding fluoride containing compounds (sodium fluoride) -which is present in Orovex mouthwashes -and antibacterial natural extracts (oil of clove) which is present in both mouthwashes -used in this current study -which may play a major role in surface deterioration and degradation of the resin based materials affecting their esthetics and surface properties (30,31) .…”

The purpose of this study was to evaluate color stability and microhardness of CAD/CAM Cerasmart hybrid ceramic blocks after different immersion times in chlorohexidine and new plantbased mouth wash. Materials and Methods:A total of 120 square discs (10x12x1mm) were cut from 12 hybrid ceramic CAD\CAM blocks (shade A1\1M2, C12, 10x12x15mm, Cerasmart, GC) with a diamond blade (Isomet 15LC; Buehler) mounted in a cutting machine (Buehler). Specimens were divided into three equal groups (n=40) according to immersion media, either, distilled water (DW), chlorohexidine mouthwash (CM) (Orovex, Macro Group pharmaceuticals, Egypt) or Neem (Azadirachata indica) mouthwash (NM) (Neem Mouthwash, Theraneem Naturals, USA). Each group was subdivided into four equal subgroups (n=10) according to immersion time, either one hour and half, three hours, 18 hours or 36 hours. After each time interval, specimens were stored in DW at 37°C till time of evaluation of color change and micro-hardnesss.Results: Two ways ANOVA showed that the immersion media had a statistically significant effect on the VHN and ΔE of Cerasmart at a p-value= 0.0001 for both, also significance was detected for the effect of immersion time on the VHN and ∆ E of Cerasmart at a p-value= 0.0001 for both. Conclusion:Long term usage of antimicrobial mouthwashes used in this study (more than one year) should be avoided due to its negative effect on surface microhardness of the used resin based CAD/CAM restorations. Prolonged use of Neem mouthwash had a minimal effect on color change on the used resin based CAD/CAM restorations compared to CHX containing mouth wash (Orovex).

“…Similar to our result Gill and Pathak 4 did not find any significant difference in the microhardness of conventional GIC (Fuji II) after sodium fluoride (NaF) gel treatment; however, their result on Fuji IX contradicted with our result, which could be due to the different efficacy and reactivity of fluoride components of sodium fluoride gel and varnish with the matrix of restorative material. 23 …”

A bstract Background and objectives Fluoride varnishes are being used to prevent caries in children. The high concentration of fluoride in varnishes apart from caries prevention may cause changes in surface properties of esthetic restorations. The study aims to evaluate and compare the effect of four commercially available fluoride varnishes with added calcium and phosphate on microhardness of three esthetic materials namely conventional GIC (Fuji II), high viscosity GIC (Fuji IX), and nanocomposite (Filtek Z350). Materials and methods A total of 28 pellets were made of each material and stored in distilled water at 37 °C for 48 hours. The microhardness of the pellets was tested which served as a baseline. These were then randomly divided into four subgroups. In one subgroup Profluorid varnish was applied, second subgroup MI varnish was applied, third subgroup Embrace varnish was applied, and in the fourth subgroup Enamel Pro varnish was applied as per protocol. Thereafter, all the pellets were subjected to microhardness testing (load = 100 g for 15 seconds). Results The fluoride varnishes increased the microhardness of conventional GIC (Fuji II) whereas in case of high viscosity GIC (Fuji IX) the application of varnishes reduced the microhardness. In case of nanocomposite restorative material (Filtek Z350) only Profluorid varnish increased its microhardness. Conclusion Fluoride varnish and calcium-phosphate containing fluoride varnish effect on the microhardness of restorative material is material dependent. So, the choice of fluoride varnish with or without proprietary additives depends on the nature and composition of the restorative material.

“…It has been reported that fluoride varnish application negatively affects the color stability of restorative materials ( 25 ). Fatima et al ( 26 ) stated that APF gel application on the GIC and RMGIC materials resulted in significant color change. While there are many studies investigating the color change caused by fluoride containing mouthwashes and local fluoride applications, the number of studies examining the color change caused by dentifrices with different fluoride formulation is very limited ( 1 , 19 , 24 , 25 , 26 , 27 ).…”
