Internal Energy02:00

Internal Energy

36.9K
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

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...

Internal Receptors01:31

Internal Receptors

74.7K
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.

International System of Units01:29

International System of Units

5.2K
The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...

Internal and External Forces01:12

Internal and External Forces

16.4K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

International Nursing Organization (ICN) is a global union of national nurses' organizations. Individual nurses can be a part of ICN through member organizations. Each member organization strives to ensure quality nursing care, sound health policies, the advancement of nursing knowledge, respect for the profession, and a satisfied and competent nursing workforce.
ICN member organizations work to advance the field of nursing and healthcare via policies, partnerships, lobbying, professional...

Summary

Extensive internal tunneling resorption (ITR) and invasive cervical resorption (ICR) in a tooth were successfully treated non-surgically. Biodentine (BD) effectively repaired the defects, leading to long-term tooth function and healing.

Area of Science:

  • Endodontics
  • Dental Traumatology
  • Restorative Dentistry

Background:

  • Pathological tooth resorption, particularly internal tunneling resorption (ITR) and invasive cervical resorption (ICR), presents significant treatment challenges, especially when extending beyond root confines.
  • Accurate diagnosis and management are crucial for preserving tooth function and preventing complications like apical periodontitis.

Observation:

  • A case report details the non-surgical management of a 22-year-old male with a discolored maxillary right lateral incisor exhibiting extensive ITR and ICR.
  • Preoperative assessment using cone-beam computed tomography (CBCT) confirmed the extensive nature of the resorption and associated apical periodontitis.

Findings:

  • Following chemomechanical debridement and intracanal calcium hydroxide medication, Biodentine (BD) was used for obturation and restoration of the resorptive defects.
  • A 5-year follow-up revealed the tooth remained functional with evident periapical healing, indicating successful resolution of apical periodontitis.

Implications:

  • This case suggests that Biodentine (BD) can be an effective bioactive material for repairing extensive ITR and ICR defects, potentially leading to favorable outcomes.
  • CBCT imaging is vital for precise visualization and assessment of complex resorptive defects.
  • Successful management of such defects highlights the importance of timely and appropriate endodontic intervention following dental trauma.
