The Effect of Egg Shell Versus Fluoride Varnish on Remineralization of Early Enamel Demineralized Lesions

Abstract

Twenty freshly extracted non-carious human molars were used. The mineral content of all teeth was initially assessed using EDX. Teeth were then divided randomly into two groups each containing ten samples. All teeth were placed in demineralizing agent after which one group (I) was remineralized using egg shell solution while the other group (II) was remineralized using fluoride varnish (Proshield, President dental Germany). This process was held in a pH cycling mode.Regarding mineral content specimens of both groups were initially assessed (base line measurements), then reassessed directly after demineralization, three days from remineralization and at the end of seven days remineralization period. Results were as follow : Regarding Ca wt % and comparing the two groups there was no statistical significance at base line measurements, after demineralization and after three days from remineralization. Meanwhile after seven days remineralization group (I) demonstrated statistically significant lower mean Ca atomic wt % than group (II). Regarding phosphorus atomic wt % for measurements of base line, after demineralization and after remineralization there was no statistical significance between the two groups. Regarding the effect of time for Ca wt % and after seven days group (I) showed non statistically significant decrease in Ca wt % compared to that at base line, while group (II) showed non statistically significant difference from the value measured at base line. For the P wt % and after seven days both groups demonstrated non statistically significant lower mean values compared to base line data.

Nano eggshell‐based slurry as a direct pulp‐capping material: In vitro characterization and histopathological assessment in an experimental animal model

“…However, it was suggested the fine particle sizes of the NES as well as the presence of trace elements in its crystals could contribute to enhancing the solubility of CaCO 3. Thus, the CaCO 3 dissociates into CO 2 and calcium oxide (CaO) (Bai & Bai, 2019;Chilingar et al, 2008;Esberard et al, 1996;Kralj & Brečević, 1995).…”

“…Although the literature reported various studies related to the use of bioactive eggshells in different applications, fewer studies concerning the application of eggshells in the dental field have been published. Eggshell has demonstrated the remineralizing ability of early enamel demineralized lesions (Fares et al, 2018), and as an effective desensitizing agent as compared with casein phosphopeptide‐amorphous calcium phosphate (CPP‐ACP) containing Tooth Mousse (Tahlawy et al, 2021). In addition, HAp‐based eggshells showed superior properties when compared with HAp synthesized from other sources in terms of sinterability, hardness, density and in vitro biocompatibility (Abdulrahman et al, 2014).…”
