“…Characterization of prepared CESP revealed presence of high calcium content (51.55 wt%), (Figure 2,b); which was in agreement with many studies (7,24) . Since eggshell was proven as a promising biomaterial for remineralization of dentin defects, implementation of that cost-effective product might reduce the need of other expensive sources of calcium like MTA and BD (Metal Trioxide Aggregate and Biodentin) that had reported highest recorded number of complete dentin bridge formation (11,22,30) . The prepared eggshell collagen delivering device was effectively remineralizing deepest critical points in tooth cavities and had formed the prospected calcific dentin bridge as shown in (Table 1, Figure 2,g).…”

“…A 0.1 gm of prepared eggshell powder was morphologically characterized using a highresolution scanning electron microscope (SEM), [Model Quanta 250 FEG (Field Emission Gun), FEI Company, Netherlands]. In addition, the elemental composition of eggshell powder was assessed with an energy-dispersive X-ray spectroscopy (EDX) [Quanta FEG 250 FEI, USA] device using EDXA apex software (11) .…”

Objective of the study was to evaluate the remineralizing effect of a prepared chicken eggshell powder (CESP) containing solution on human dentine and to compare it to that of light curing calcium hydroxide (Ca-OH) cavity liner. Chicken eggshell powder was prepared, characterized using a scanning electron microscope (SEM) and an energy-dispersive X-ray spectroscopy (EDX). A total of 24 patients were selected from operative dentistry clinic, each patient had at least two occlusal deep carious defects in permanent premolars or molars. After complete caries excavation, the 48 teeth were divided into two groups (n = 24): according to the received treatment: eggshell collagen delivering device (group 1) and light curing Ca-OH (group 2) as indirect direct pulp capping biomaterials. Teeth were then restored by a reinforced glass ionomer base and a permanent resin-based composite (RBC) filling. Cone beam computed tomography (CBCT) radiographs were used to evaluate and compare the variation in thickness of inducted dentine bridge immediately after insertion of final restoration and after 6months to evaluate thickness of dentine bridge finally the measurements were statistically evaluated by paired t test. Results showed that the group of teeth treated by pulp capping using the prepared remineralizing eggshell delivered by kolspon sponge showed a significantly higher thickness of dentin bridge formation than the group that was managed by application of conventional Ca-OH pulp capping agent. Concluding that A prepared chicken eggshell powder (CESP) in reminerization solution loaded into a collagen kolspon sponge might serve successfully in induction of newly formed reparative dentine bridge.

“…Furthermore, biomimetic HA differs from synthetic HA form in terms of stoichiometry, composition, degree of crystallinity (37,38) . Therefore, biomimetic HA demonstrated a smart biodegradation rate and an overall marvelous biological performance that rendered it appropriate to repair the skeletal calcified tissues (38)(39)(40) .…”

AIM:The study aimed to investigate the remineralizing potential of two freshly prepared organic biomimetic waste nanomaterial [fish bone (FB) and chicken eggshell (ES)] solutions on partially demineralized human enamel surface using Energy dispersive X-ray spectroscopy (EDX) for quantitative Ca/P assessment.The study aimed to investigate remineralizing potential of two organic biomimetic waste nanomaterials [fish bone (FB) and chicken eggshell (ES)] on demineralized enamel using Energy Dispersive X-ray spectroscopy (EDX) for quantitative calcium/ phosphate assessment. A total of 34 freshly extracted human 3 rd molars were collected to be used. Thirty teeth were divided into three equal groups (n=10). Group1: Teeth represented the control group as a reference for the assessed normal quantitative content of calcium and phosphorus. Group2: Teeth were immersed in a freshly prepared demineralizing solution for 96 hours, then investigated by EDX. Afterword, those group 2 teeth were again soaked in a freshly elaborated remineralizing fish bone nanoparticle solution for 189 hours, then reevaluated by EDX. Group3: Teeth were demineralized with the same regime as group 2 teeth, then remineralized in a freshly prepared ES nanoparticle solution for seven days to be again reassessed by EDX. In addition, the remaining four human teeth were assessed by a scanning electron microscope (SEM); where 1 sound enamel surface was scanned, a second tooth was SEM investigated following demineralization regime, a third one was SEM assessed after remineralization with FB nanoparticle solution and fourth one scanned after ES nanoparticle remineralization. Paired sample t-test and independent t test statistical analysis were used. Freshly prepared nano FB and ES solutions seem promising for remineralization of incipient enamel lesions.

“…Egg shell dentine pretreatment group showed significantly higher µTBS mean values than the control group , as the egg shell solution had a pH of 11.7 which increases the activity of hydroxyl ions ,so the water remained in dentinal tubules and collagen fibrils facilitates the movement of calcium ion, moreover,10-MDP (10-methacry-loxydecyl dihydrogen phosphate) in universal adhesives bonds to calcium ions chemically in dentinal tubules and collagen fibrils forming a thicker hybrid layer (31) .…”

Purpose: This study was conducted to evaluate the effect of egg shell and white tea dentin pre-treatment on microtensile bond strength between resin composite and dentin surface. Materials and Methods: Forty-five extracted molar teeth were divided into three subgroups according to dentin pretreatment ; with no treatment (control ), Egg shell, and white tea. Each group was subdivided for microtensile testing into three equal subgroups, either after 24 hours (T0), after1 month (T1), and after 3 months (T2).The occlusal enamel was removed. And according to each group one of pretreatments was used. Resin composite blocks were fabricated on dentin after application of self etch adhesive. The teeth were longitudinally sectioned to get composite-dentin beams, two central beams were selected from 45 teeth in order to have 90 beams. Specimens were assessed after 2 storage periods in artificial saliva: either one month (T1) or three months (T2) storage period. Specimen were subjected to microtensile bond strength testing. Results: at T0, there was no statistically significant difference in mean μTBS between different dentin pre-treatments, while at T1 and T2, white tea group showed significantly the highest μTBS mean values, followed by egg shell group, then control group. Conclusion: Natural remineralizing agents could enhance microtensile bond strength of universal bonding system in self etch mode, and remineralizing potential of natural agents has stabilized by time.
