Summary
An orthodontic archwire was unexpectedly found in a patient's nasal cavity after self-manipulation detached it. This case highlights the importance of recognizing and preventing foreign body complications in orthodontic treatment.
Area of Science:
- Dentistry
- Orthodontics
- Medical Imaging
Background:
- Orthodontic treatment involves the use of archwires to guide tooth movement.
- Accidental displacement or loss of orthodontic appliances can occur.
- Foreign body ingestion or inhalation is a rare but serious complication.
Observation:
- A patient self-manipulated and detached an orthodontic archwire from brackets.
- The detached archwire was not immediately recognized as lost.
- A routine end-of-treatment radiograph revealed the archwire in the patient's nasal cavity.
Findings:
- The asymptomatic presence of a foreign body (orthodontic archwire) in the nasal cavity.
- Successful management and removal of the misplaced archwire.
- The importance of thorough examination and patient education in preventing such incidents.
Implications:
- Highlights the potential for asymptomatic foreign body migration in orthodontic patients.
- Underscores the need for vigilance in diagnosing and managing foreign body complications.
- Emphasizes the critical role of routine radiographic evaluation in orthodontic treatment completion.

01:24Nose and Nasal Cavity
12.1K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:28Standing Waves in a Cavity
1.5K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

01:26Masonry Cavity Walls

Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.

01:29Administering Oxygen by Nasal Cannula
3.4K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
