A periodontal attachment mechanism without alveolar bone. Case report

Area of Science:

• Dentistry
• Periodontology
• Developmental Biology

Background:

• Periodontal disease is a common condition characterized by bone loss.
• This case presents atypical radiographic findings of advanced bone loss in a young adult.

Observation:

• Clinical examination showed gingivitis but minimal clinical attachment loss.
• Laboratory tests for blood counts, serum chemistry, and neutrophil function were normal.
• Histological analysis of an extracted tooth revealed collagen-poor, afibrillar cementum.

Findings:

• The cementum structure differed significantly from normal, resembling afibrillar cementum.
• No evidence of periodontal attachment loss was found histologically.
• Radiographic bone loss was disproportionate to clinical findings.

Implications:

• Suggests a localized developmental anomaly in periodontal structures.
• Highlights the importance of considering developmental defects in atypical periodontal cases.
• May inform future research on cementum development and periodontal health.
