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...

Multiple Regression

4.0K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Modified Boxplots

11.3K
A standard box and whisker plot informs us about the spread of the data in a given sample. One can identify the minimum value, maximum value, first quartile value, second quartile or median value, and third quartile.
However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
Initially, we calculate the adjusted...

Frustration and Conflict: Approach-Approach, Approach-Avoidance

544
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Multiple Voltage Sources01:25

Multiple Voltage Sources

1.8K
Generally, a single battery is not enough to power some devices. In such cases, batteries can be combined in two ways: in series or in parallel.
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
Batteries are...

Summary

This study presents a modified free gingival graft (FGG) technique for increasing keratinized tissue in extensive areas. The innovative approach uses a smaller graft with incisions, proving effective in enhancing attached gingival tissue and oral hygiene.

Area of Science:

  • Periodontology
  • Oral surgery

Background:

  • Increasing keratinized attached tissue is crucial for oral hygiene and preventing attachment loss.
  • Large recipient areas pose challenges for traditional free gingival graft (FGG) techniques.
  • The need for effective FGG methods in extensive sites is well-established.

Observation:

  • A modified FGG technique was applied to two patients with extensive recipient areas.
  • A template 25%-30% smaller than the recipient area was used to harvest the graft.
  • Interspersed incisions were made on the graft's edges after harvesting.

Findings:

  • The modified FGG technique resulted in a 4.0-4.4 times increase in keratinized tissue width.
  • The technique successfully increased attached gingival tissue in large recipient areas.
  • The procedure facilitated improved oral hygiene and prevented further clinical attachment loss.

Implications:

  • This modified FGG technique offers a viable alternative for augmenting keratinized tissue in extensive areas.
  • The use of a smaller graft with specific modifications can achieve significant clinical outcomes.
  • The findings suggest potential for improved patient outcomes in periodontal plastic surgery.
