Teeth01:15

Teeth

1.8K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Trial and Error and Algorithm01:12

Trial and Error and Algorithm

409
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

What are Estimates?

8.8K
It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate the mean height or mean weight of the individuals in the sample. This sample data acts as a representative measure of the population parameter. These sample statistics are known as estimates. 
The estimate for the mean of a sample is denoted by ͞x, whereas the mean of the population is designated as μ. Further, parameters such...

Cell Size01:22

Cell Size

127.3K
Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.
Surface Area
Cells can take in nutrients and water via diffusion through the plasma membrane itself or through specific channels in the membrane. The area of the membrane surrounding...

Estimation of k and VD of Aminoglycosides

242
Aminoglycosides are a class of antibiotics used to treat various bacterial infections. Clinicians must determine the elimination rate constant (k) and volume of distribution (VD) to optimize therapeutic efficacy and minimize toxicity. The k value represents the rate at which the drug is removed from the body, and the VD reflects the degree to which the drug distributes into body tissues. Accurately estimating these parameters allows healthcare professionals to tailor drug dosing to individual...

Microbial Morphologies

2.7K
Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

Area of Science:

  • Dentistry
  • Biomedical Engineering
  • Anthropology

Background:

  • Complete absence of teeth (edentulism) presents significant challenges in prosthetic treatment.
  • Accurate determination of artificial tooth size is crucial for functional and aesthetic denture outcomes.
  • Current methods may lack precision, necessitating improved algorithms for personalized prosthetic design.

Purpose of the Study:

  • To develop and validate an algorithm for determining artificial tooth size based on facial morphometric parameters.
  • To enhance prosthetic treatment for edentulous patients through precise dental measurements.
  • To integrate mathematical-graphic modeling for improved denture design.

Main Methods:

  • Involved 76 elderly and senile adults with complete edentulism.
  • Utilized mathematical-graphic modeling and analytical methods to derive correction factors.
  • Developed an algorithm correlating diagonal facial parameters with artificial tooth dimensions.

Main Results:

  • An algorithm was developed using optimal ratios of diagonal facial parameters and mesial-distal dimensions of 14 upper jaw artificial teeth (correction factor 2.2).
  • The width of anterior artificial teeth on the upper jaw correlated with the total width of 14 artificial teeth (correction coefficient 2.45).
  • An intermaxillary correction factor of 1.07 was established for upper to lower jaw artificial tooth width ratios.

Conclusions:

  • The developed algorithm provides a mathematically tested and clinically justified method for determining artificial tooth size in denture prostheses.
  • Facial morphometric parameters, combined with specific correction factors, offer a reliable approach to prosthetic dental design.
  • This approach aims to improve the success and patient satisfaction in prosthetic treatment for edentulous individuals.
