Tooth Anatomy01:21

Tooth Anatomy

2.1K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Extraction: Effects of pH

1.3K
Consider a neutral form of an amine, B, with a partition coefficient, K, in a liquid mixture containing organic and aqueous phases. The pH of the aqueous phase affects the charge on acidic and basic solutes, and the charged form is usually more soluble in the aqueous phase. Suppose the conjugate acid form of the amine is soluble only in the aqueous phase while the base form is soluble in both phases. Then the distribution coefficient, D, can be given as the ratio of amine concentration in the...

Extraction: Advanced Methods

1.1K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Extraction: Partition and Distribution Coefficients

4.6K
The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.
For extracting a solute from an aqueous phase into an...

DNA from cells is required for many biotechnology and research applications, such as molecular cloning. To remove and purify DNA from cells, researchers use various methods of DNA extraction. While the specifics of different protocols may vary, some general concepts underlie the process of DNA extraction.

What is Glycolysis?00:56

What is Glycolysis?

176.4K
Overview
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...

Area of Science:

  • Dentistry
  • Orthodontics
  • Dental Surgery

Background:

  • Tooth crowding and protrusion are common orthodontic issues requiring careful treatment planning.
  • Extraction of premolars, specifically first and second premolars, is a frequent approach in managing these malocclusions.
  • Accurate diagnosis involves assessing dentoalveolar bone, maxillomandibular relations, facial profile, skeletal maturation, dental asymmetries, and patient cooperation.

Purpose of the Study:

  • To discuss treatment options involving dental extractions in orthodontics.
  • To describe the successful correction of a specific Class I malocclusion case with bimaxillary protrusion and severe crowding.

Main Methods:

  • The study focuses on treatment strategies involving premolar extractions.
  • A case report details the correction of severe anterior crowding in both arches and tooth-size discrepancy.
  • First premolar extraction was the chosen method for this particular case.

Main Results:

  • First premolar extraction effectively addressed severe anterior crowding in both dental arches.
  • The treatment successfully corrected the Class I malocclusion and bimaxillary protrusion.
  • Patient cooperation and accurate diagnostic factors contributed to the positive outcome.

Conclusions:

  • First premolar extraction is a viable and effective treatment option for managing severe anterior crowding and bimaxillary protrusion in Class I malocclusions.
  • Comprehensive orthodontic diagnosis is crucial for successful treatment outcomes.
  • Extraction decisions should be individualized based on patient-specific characteristics.
