Abstract Introduction: The zinc oxide–eugenol (ZOE) sealer is used till now in many private dental clinics although sealers have been developed. current study aimed to compare the biocompatibility and remineralizing capacity of ZOE following addition nanohydroxyapatite-tyrosine amino acid. Materials Methods: Twenty rabbits were this investigation, they divided into four groups based on test observation period (3, 7, 21, 28 days) surgical implantation. General anesthesia was given for each rabbit with a subcutaneous incision about 1 cm ± 0.5 made along symphyseal area mandible rabbit. Each had bone cavities generated interdental space lower jaw between central molar teeth, one longitudinal incision. mixed directly inserted within as follows: alone right side (Group A), 10% nHAp Tyrosine at B), empty cavity (−ve control) located left C) 20%/nHAp D). Animals scarified biopsy samples from tested parts collected. Histological analysis performed using low-power light microscope immunohistochemistry runt-related transcription factor 2 (Runx2) antibody. Data statistically analyzed utilizing SPSS software. One-way variance post hoc Duncan’s utilized measure significance among various P ≤ 0.01. Results: inflammatory process decreased over time all experimental groups, associated an increase granulation tissue formation which gradually decreasing permit new blood vessels that increased time. Group D displayed highest levels formation. Runx2 antibody expression declined progressively, particularly days. Conclusion: Superior biocompatible properties demonstrated by 20% tyrosine sealer.

In Pakistan, the global warming and liquefaction problems have increased due to CO2 emissions during thecement manufacturing process water absorption ability of cement, respectively. Recently, enzyme-inducedcarbonate precipitation (EICP) has become increasingly popular its eco-friendly nature mechanical properties.This study is aimed extract crude urease enzyme from watermelon seeds, considered "food waste," test effectson biocementation produce a building material with more strength less permeability for absorption.Watermelon seeds were used in dry germinated conditions investigate activity calcium carbonateformation. The EICP-coated brick showed weight change than control brick. bricks added cycles (1,7, 14 times); 14-cycle was firmer other two bricks, but still wasn't sufficiently durable. Therefore toovercome this problem, another EICP method used, which one-phase method, large volume EICPsolution mixed sand same brick, compacted mold again. incubated at 35–37 ˚Cand cured days, resulting hardened A conducted on sample, it wasfound that bio could not endure long period time. Scanning Electron Microscopy(SEM) confirmed major vaterites formed instead calcite, cause some disintegration thebio However, suggested solution can be as binder crack-filling.
