The eggshell and the eggshell membrane (ESM) are significant by-products of the poultry industry and are being utilized for various valuable purposes in health care, like soft tissue healing and pain alleviation. The aim and objective of our study are to assess the effect of the eggshell membrane on alveolar bone regeneration after tooth extraction. A total of 40 extraction sockets (bilateral) among 20 patients were assessed clinically for healing, and radiographic parameters of bone density and socket volume were assessed on CBCT at baseline, 3 months, and 6 months. Advanced platelet-rich fibrin was created from 5 ml of autologous blood from the patient and centrifuged for 15 minutes at 1500 RPM/168 RCF. The commercially available powdered form of egg shell membrane was used in the study. Based on the randomized allotment (coin-flip), A-PRF alone or A-PRF mixed with eggshell membrane was placed inside the extraction socket and was stabilized using 3-0 silk sutures. It was ob-served that wound healing was uneventful in all 20 patients. No evidence of dry sockets or allergic reactions was noted in any patient. Statistical analysis was done using the un-paired t-test and Mann-Whitney U test with SPSS version 20.0. P<0.05 was considered significant. On comparison of the mean bone density at baseline, 3 months, and 6 months, the socket density in the eggshell with the PRF group was higher compared to the control group. To conclude, eggshell membrane has good regenerative properties and excellent osteogenic capacity; therefore, it could be a useful graft due to its low cost, abundant availability, and simple application.

The eggshell membrane (ESM), resembling the extracellular matrix (ECM), acts as a protective barrier against bacterial invasion and offers various biofunctions due to its porous structure and protein-rich composition, such as ovalbumin, ovotransferrin, collagen, soluble protein, and antimicrobial proteins. However, the structure of ESM primarily comprises disulfide bonds and heterochains, which poses a challenge for protein solubilization/extraction. Therefore, the method of dissolving and extracting bioactive protein components from ESM has significant potential value and importance for exploring the reuse of egg waste and environmental protection.

Using our recently developed laser speckle contrast imaging (LSCI) to visualize blood vessels and monitor blood flow noninvasively, we test the utility of the developing chick heart as a functional model for drug screening. To this end, we examined the effects of antihypertensive agents Nifedipine and Amlodipine, belonging to the L-type calcium channel antagonist family, on blood flow visualized noninvasively through the intact shell. Guided by the live view mode, the drugs were injected through the shell and ventral to HH16-19 chick embryos.

Conventional methods of guided bone regeneration (GBR) in bone tissue engineering frequently encounter challenges in attaining adequate antibacterial and osteogenic qualities owing to intrinsic limits. The purpose of this preclinical study was to assess the effectiveness of two distinct membranes, Healiguide® and a unique GBR membrane produced from eggshell membranes (ESM), in combination with bone graft replacement in animal models. The objective of this study was to evaluate the efficacy of a new guided bone regeneration membrane developed from eggshell membrane that incorporates zinc nanoparticles for the regeneration of bone tissue in rabbit models.

Eggshell translucency is the common problem on eggshell that become more severe with age. They are important because it influence consumer preferences and the economic value of eggs. The reason for the eggshell translucency is currently believed to be the eggshell membrane (ESM).
