RESUMEN
RESUMEN Este estudio se realizó para evaluar la presentación de cambios histopatológicos tempranos en sacos pericoronarios de terceros molares incluidos sanos. Sesenta y un tejidos pericoronarios de terceros molares incluidos, clínicamente asintomáticos y sin evidencia radiográfica de anomalía del saco pericoronario, se extrajeron por diferentes razones. Las muestras se fijaron y procesaron de forma rutinaria y se tiñeron con hematoxilina-eosina antes de la evaluación. Se estandarizaron los diagnósticos concluyendo que toda muestra que presente metaplasia escamosa del epitelio reducido del órgano del esmalte (EEE) se considerará cambio quístico temprano. De las muestras presentadas, el 28 % mostró metaplasia escamosa sugerente de cambio quístico temprano. Esta variación histológica del tejido pericoronario fue significativamente mayor en los pacientes menores de 20 años de edad, sexo femenino, terceros molares mandibulares, en inclusión ósea y en pacientes que no informaron sintomatología local previa (P = 0,05). Estos hallazgos sugieren que la ausencia de semiología clínica y radiográfica en terceros molares incluidos no necesariamente indica ausencia de alteraciones en el tejido pericoronario de los mismos.
ABSTRACT
ABSTRACT 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.
