Histology of external and internal resorption

Area of Science:

• Dentistry
• Oral Pathology

Background:

• Tooth resorption is a pathological process where tooth structure is lost.
• Internal and external resorption are distinct forms with varying etiologies.

Purpose of the Study:

• To describe and analyze seven distinct cases of tooth resorption.
• To investigate the characteristics and potential causes of internal and external resorption.

Main Methods:

• Case study analysis of seven patients presenting with tooth resorption.
• Histopathological examination of resorptive areas, including identification of calcified materials and cellular components.

Main Results:

• Three cases exhibited internal resorption with dentine penetration.
• One case showed internal resorption possibly linked to pulp carious involvement.
• Two cases of external resorption presented with dissimilar origins, one possibly infection-related, the other idiopathic.
• Calcified materials were prevalent in resorption sites; odontoclasts were identified in one case.

Conclusions:

• Tooth resorption presents with diverse clinical and etiological features.
• Internal and external resorption require careful diagnosis due to varied underlying causes.
• Further research is needed to fully elucidate the mechanisms of tooth resorption.
