Summary
Dermatoglyphics, or fingerprint patterns, can help predict molar terminal planes in children's primary teeth. Specific fingerprint patterns correlate with mesial step, distal step, and flush terminal planes in deciduous dentition.
Area of Science:
- Odontology
- Forensic Science
- Human Genetics
Background:
- Investigating the relationship between dermatoglyphic patterns and molar terminal planes in deciduous dentition.
- Understanding developmental correlations in primary dentition.
Purpose of the Study:
- To assess the correlation between different dermatoglyphic patterns and terminal planes in deciduous dentition.
- To explore the predictive potential of dermatoglyphics for dental development.
Main Methods:
- Recruited 300 children aged 3-6 years with complete primary dentition.
- Recorded molar terminal plane patterns and analyzed fingerprint patterns (including ridge counts) from distal phalanges using ink and roller method.
- Classified fingerprint patterns according to Galton's system.
Main Results:
- Ulnar loop pattern was the most common dermatoglyphic pattern.
- Mesial step was associated with absent arch patterns on the left ring and little fingers and higher left little finger ridge count.
- Distal step correlated with whorl patterns on bilateral middle fingers and a higher total left-hand ridge count.
- Flush terminal plane was linked to the absence of an arch pattern on the left ring finger.
Conclusions:
- Dermatoglyphics serves as a non-invasive tool for predicting terminal planes in primary dentition.
- Fingerprint analysis offers insights into dental development in early childhood.

01:44Termination of Translation
27.7K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

01:11Work Done Over an Inclined Plane
4.0K
The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can be ignored, and the external forces can be considered in the work-energy theorem.
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

01:21Coordinate Plane
335
The Cartesian coordinate plane is a fundamental structure in mathematics that enables the visualization of relationships between numerical values in two dimensions. It is formed by two intersecting number lines: a horizontal x-axis and a vertical y-axis. These axes meet at the origin, the point where both values are zero. Their intersection divides the plane into four quadrants labeled in a counterclockwise direction starting from the upper right.An ordered pair of numbers represents every...

02:16Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes
16.0K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...
