Abstract

In this study, the cranium of adult rats was used to examine the craniofacial anatomical markers of rats (Rattus Novergicus). This analysis helps determine key points for diagnosis. Markers on the rat skull were determined to establish measurements at two specific points. One way to validate craniofacial growth is to use Micro-Computed Tomography (micro-CT) as a marker of craniofacial growth by looking at craniofacial differences before and after a certain time. Micro-CT as an alternative diagnostic tool, especially for difficult surface areas to reach or measure. Sample analysis was performed and measured with the DataViewer Application version 1.6.0.0 64-bit. CTVox version-3.3.1 64-bit is used to display 3D visuals. After adjusting the data range, the reconstruction results are 30-255 (color range 0-255). The soft tissue of lower density is reduced to expose the hard tissue fully. The machine used is the Bruker SkyScan-1173 High Energy Micro-CT. Determination of the growth of the cranium in mice can be seen at the dorsal suture, Conca nasalis, and sphenoid base (cranial base). The uneven surface of the skull makes manual measurements difficult and impossible. However, this micro-CT method makes determining landmark points more detailed and has high accuracy or validity. This makes craniofacial geometric measurements more accurate and measurable. Micro-CT is an alternative diagnostic tool for measuring cranial growth in Rattus Novergicus, which cannot be achieved with 2D x-ray methods.

Abstract

In this study, an adult rat's calvaria was used to examine craniofacial anatomical landmarks of maxilla and mandible using Micro-Computed Tomography (micro-CT) as the marker of craniofacial growth and development in rat. It is used to assist research, translating landmark points for diagnosis. Landmarks on the rat’s calvaria were determined to set the measurements of two specified points. One of the ways to validate craniofacial growth and development is to look at the differences between craniofacial before and after a specified period or treatment. With micro-CT analysis, the researchers are more precise in determining the difficult points in the cranium.The sample analysis was carried out and measured by DataViewer version 1.6.0.0 64-bit Application. CTVox version-3.3.1 64-bit is used to display 3D visuals. Reconstruction results after adjusting the data range were 30-255 (the color range 0-255). The machine used was Bruker SkyScan-1173 High Energy Micro-CT. Findings anatomical landmarks for the examples, the maxilla determined I for the point on premaxilla between jawbone and lingual surface of upper incisors. In the mandible, I’ for the most anterior edge of the alveolar bone on the convexity of the lower incisor. The unevenness of the cranium made manual measurements difficult and not possible. However, this micro-CT method makes the landmark point determination more detailed and dependable. This makes geometric measurements of craniofacial more reliable. Micro-CT analysis is a more dependable method to determine anatomical landmarks and measure craniofacial structures as the marker of craniofacial growth and development in rat.
