Cellular Injury IV: Necrosis

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...

Area of Science:

Orthodontics
Periodontology
Oral Surgery

Background:

The Nance palatal arch is used in orthodontics to prevent maxillary molar movement.
Maintaining oral hygiene around this appliance is challenging, potentially leading to complications.

Observation:

A 22-year-old male experienced palatal mucosa necrosis and exposed bone with the Nance appliance.
Long-term periodontal damage was observed.

Findings:

The case demonstrates severe iatrogenic damage associated with the Nance palatal arch.
Necrosis and bone exposure resulted from difficulties in maintaining appliance hygiene.

Implications:

This case underscores the risks of Nance palatal arch use and the importance of vigilant oral hygiene.
Alternative anchorage methods should be considered to mitigate such severe periodontal and mucosal damage.
