Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Blood Sampling: The Central Auricular Artery(36) or lateral saphenous vein will be selected to collect 4 ml blood on day 0, after 8 weeks and at the end of 12 weeks. The sample will be collected in serum separating tube for investigations like blood lead count, alkaline phosphatase, calcium and phosphate level.
Tissue Sampling Technique:
A portion of 4x5 mm2 from middle third of crown labial surface will be taken for investigations. The cutting will be done by diamond disc and high speed turbine with irrigation of water to ovoid over heating of sample. Right mandibular incisors of all the rabbits will be selected for SEM and AFM. The left mandibular incisors of all the rabbits will be selected SEM-EDX and RMS analysis. All samples will be labeled and stored in sterilized container having 12% formalin for 72 hours.
Laboratory Processing:
1. Scan Electron Microscopy: Right mandibular incisor will be selected for SEM analysis. The structure and morphological features of enamel will be seen by its images. The sample will be washed with distilled water and will be dried by hot air blower at slow speed. Sixteen samples can be fixed on a sample stab at a time. Samples will be fixed on stab by double copper tape. The exposed stab will also be covered by copper tape and only the sample part will be left uncovered.
Gold coating will be done in sputter coater machine to make the surface conductor for fine details of images. The sample stab will be place in sputter machine chamber and lid will be closed. Inside the chamber, vacuum will be created and argon gas will be filled. Potential of 40 volts will be given. By this plasma will be formed inside the chamber and the electrons of argon gas will strike on gold plate. The tiny gold particles will start sputtering on sample stab. Once gold coating will be done, the procedure will be reversed. The chamber will be filled with air and lid will be opened. Now the sample will be processed in NOVA NANOSEM 450 for ultrastructural details.
2. Energy Dispersive Spectroscopy: EDX will be used to study elemental composition of mineral contents. A detector of OXFORD X-ACT, PENTA FET will be attached with NOVA NANOSEM 450. The same sample used for SEM will also be used for SEM-EDX analysis. This will give details on the surface up to 2 micron thickness.
3. Atomic Force Microscope: AFM (SPM-9500J3, Shimadzu Corp, Japan) will be used for the assessment of morphological features of enamel surface. It provides the three-dimensional surface topography without any sample preparation. This microscopy is designed to scan the sample with a probe. Sample will be attached on stub, which will be fixed and manually adjusted. Laser adjustment will be done after determining probe frequency. Finally, scanning and image processing will be done with WinSPM system processing. For one representative sample, micrographs at six different areas (2.0×2.0 μm scan area) will be taken using AFM (SPM-9500J3, Shimadzu Corp, Japan) and AFM software (SPM-Offline, Shimadzu Corp, Japan).
AFM creates 3D images of a surface by scanning a micron-size cantilever across the surface, which is typically made of silicon or silicon nitride, with a tip whose radius of curvature is \~10nm. The cantilever is deflected by the forces between the tip and the surface, which are \~nN and include contributions from electrostatic forces, solvation forces, Vander Waals interactions, and chemical bonding. This deflection of cantilever is measured by a laser spot reflecting from the top surface of the cantilever into an array of photodiodes, which provides images on the computer.
4. Raman spectroscopy: It is a non-destructive chemical analysis technique which provides detailed information about chemical structure, crystallinity and molecular interactions. The RMS will give us the details of the entire thickness of enamel about the molecular composition and its interaction of the sample. No special sample preparation will be needed for this analysis and the sample can also be used for other investigations. InVia Raman Microscope by RENISHAW UK will be used for this study. The laser intensity 488nm will be used for 10 seconds. The RMS will be done on 6 different spots and the average reading will be used in study.
