Summary
This summary is machine-generated.

Pathological external root resorption affects 17% of teeth, characterized by hard tooth substance loss. Radiological and optical coherence tomography (OCT) exams effectively detect resorption forms and etiological factors.

Area of Science:

  • Dentistry
  • Oral Pathology
  • Radiology

Background:

  • Pathological external root resorption involves hard tooth substance loss due to local or systemic factors.
  • Six distinct forms of external root resorption are recognized, including inflammatory and replacement types.

Purpose of the Study:

  • To determine the prevalence of pathological root resorption.
  • To elucidate radiological characteristics of external root resorption.
  • To describe optical coherence tomography (OCT) findings in pathological root resorption.

Main Methods:

  • Retrospective radiological study.
  • Analysis of radiological features of various external root resorption forms.
  • Comparison of OCT imaging in physiological and pathological root resorption.

Main Results:

  • Prevalence of pathological external root resorption was found to be 17%.
  • Radiological examination effectively identified resorption types and potential causes.
  • Radiological signs included radiolucency (inflammatory/invasive resorption) or root form changes (replacement resorption).
  • OCT revealed distinct signals between physiological and pathological resorption, with stronger cement signals in pathological cases.

Conclusions:

  • Radiological and OCT imaging are valuable tools for diagnosing external root resorption.
  • OCT provides detailed insights into dentin changes, such as demineralization and craters in inflammatory resorption.
  • Understanding resorption characteristics aids in identifying etiological factors and guiding treatment.
