Guided Endodontics: Three-Dimensional Planning and Template-Aided Preparation of Endodontic Access Cavities07:14

Guided Endodontics: Three-Dimensional Planning and Template-Aided Preparation of Endodontic Access Cavities

5.1K
Guided endodontics describes a template-aided approach for access cavity preparation. The procedure requires cone-beam computed tomography and a surface scan to produce a template. An incorporated sleeve guides the drill to the target point. This allows the preparation of minimally invasive endodontic access cavities in calcified teeth.

Internal Energy02:00

Internal Energy

36.5K
The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Internal Energy

6.8K
The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Dynamic Navigation in Endodontics: Guided Access Cavity Preparation by Means of a Miniaturized Navigation System

5.2K
Dynamic navigation systems (DNS) provide real-time visualization and guidance to the operator during endodontic access cavities preparation. The planning of the procedure requires three-dimensional imaging utilizing cone beam computed tomography and surface scans. After the export of the planning data to the DNS, access cavities can be prepared with minimal...

Internal Receptors01:31

Internal Receptors

74.3K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Summary
This summary is machine-generated.

Regenerative endodontic therapy (RET) can cause tooth discoloration, often recurring after internal bleaching. This case shows persistent discoloration due to materials like MTA, necessitating alternative esthetic solutions.

Area of Science:

  • Dentistry
  • Endodontics
  • Regenerative Medicine

Background:

  • Regenerative endodontic therapy (RET) is a key treatment for immature necrotic teeth.
  • Tooth discoloration is a common esthetic complication following RET.
  • Internal bleaching is a frequent but variable treatment for post-RET discoloration.

Purpose of the Study:

  • To present a case of persistent tooth discoloration after RET.
  • To discuss the challenges in managing recurrent discoloration and infection.
  • To highlight limitations of internal bleaching and material-related discoloration.

Main Methods:

  • A case report of a 15-year-old female with a discolored maxillary central incisor post-RET.
  • Initial internal bleaching followed by endodontic retreatment due to abscess formation.
  • Analysis of persistent discoloration attributed to root canal materials.

Main Results:

  • Initial internal bleaching provided temporary esthetic improvement.
  • Recurrent discoloration and abscess formation complicated treatment.
  • Persistent discoloration remained despite successful infection management, linked to MTA use.

Conclusions:

  • Tooth discoloration post-RET presents significant esthetic challenges.
  • Internal bleaching has limitations, especially with material-induced discoloration.
  • Preventive strategies and alternative esthetic treatments are crucial for RET outcomes.
