Quarrying of Stone01:15

Quarrying of Stone

Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the block.
Base Excision Repair01:54

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Area of Science:

  • Dentistry
  • Oral Surgery
  • Radiology

Background:

  • Dental extractions, while common, carry a risk of instrument-related complications.
  • Defective surgical instruments can lead to inadvertent fragment retention during procedures.

Observation:

  • A case report details a non-symptomatic retained fractured dental elevator tip.
  • The fragment was unknowingly left during an extraction performed ten years prior.
  • Routine radiographic examination led to the incidental discovery of the retained instrument tip.

Findings:

  • Three-dimensional imaging techniques were crucial in visualizing the retained fragment.
  • The patient remained asymptomatic despite the long-term presence of the foreign body.
  • This case underscores the potential for delayed detection of retained dental instruments.

Implications:

  • Dentists must meticulously inspect instruments for defects before and after use.
  • Awareness of rare complications like retained fragments is essential for surgical preparedness.
  • Careful pre-operative assessment of retained fragments is vital before considering removal strategies.
