Histopathological Findings of Pericoronary Tissue in Healthy Third Molars

Parra V. & Ibaceta G.

Summary

This study was performed to evaluate the presentation of early histopathological changes in pericoronal healthy third molars. Sixty-one pericororonitis tissues third molars, without radiographic evidence of abnormality in pericoronary sack, extracted for various reasons. The samples were fixed and processed routinely and stained with hematoxylin-eosin before evaluation. Diagnostic standardized concluding that all this shows that squamous metaplasia of the reduced enamel organ (EEE) is considered cystic epithelium were early change. Of the samples submitted, 28 % showed squamous metaplasia early suggestive of cystic change. This histological tissue pericoronary variation was significantly higher in patients under 20 years of age, female gender, mandibular third molars, including in bone and in patients who reported no previous local symptoms (P = 0.05). These findings suggest that the absence of clinical and radiographic semiology third molars does not necessarily indicate the absence of alterations in tissue pericoronary thereof.

KEY WORDS: pericoronary tissue, third molar, histopathology.
