ABSTRACT

UNLABELLED: The aim of this study was to determine the relative frequency and distribution of reactive hyperplastic lesions (RHL) of the oral mucosa at the Oral Pathology Institute of the School of Dentistry at the University of Chile. This was a retrospective study of 1149 biopsies with histopathological diagnosis of RHL, performed between 2000 and 2011. The RHL were classified in 4 groups: fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral giant-cell granuloma (PGCG) and peripheral ossifying fibroma (POF). RESULTS: the most frequent RHL was FH (71. 1%), followed by PG (21.1%), PGCG (5 %) and POF (2.9%). RHLs were more frequent in women (70.7%). The most highly affected age group was the 50- to 59-year-olds (22%). The most frequent location for RHL was maxilla (24.7%), followed by cheek (20.6%), tongue (19.4%) and jaw (18.5%). The most prevalent RHL diagnosis was FH. The most frequently affected sex was female, the most frequent age range was 50-59 years, and the most frequent location, maxilla.

ABSTRACT

El objetivo de este estudio fue determinar la frecuencia relativa y distribución de lesiones reaccionales hiperplásicas (LRH) de la mucosa oral, presentes en el registro de biopsias del Servicio de Anatomía Patológica de la Facultad de Odontología, Universidad de Chile. Este estudio de tipo retrospectivo consistió en 1149 biopsias con diagnóstico histopatológico de LRH, entre los años 2000-2011. Las LRH se clasificaron en 5 grupos: Hiperplasia fibrosa (HF), granuloma piogénico (GP), granuloma periférico de células gigantes (GPCG) y fibroma osificante periférico(FOP). Los datos de edad y sexo de los sujetos, y de localización y tipo de lesión, fueron obtenidos del registro de biopsias de cada caso. De las LRH, la lesión más frecuente fue HF (71,1 por ciento), seguido de GP (21,1 por ciento), GPCG (5 por ciento) y FOP (2,9 por ciento) respectivamente. Las biopsias de LRH fueron mas frecuentes en mujeres (70,7 por ciento). El rango etario más afectado fue el de 50 a 59 años (22 por ciento). La localización de mayor frecuencia de LRH fue el maxilar superior (24,7 por ciento), seguida de mejilla (20,6 por ciento), lengua (19,4 por ciento), mandíbula (18,5 por ciento), labio inferior (9,9 por ciento) y labio superior (6,7 por ciento). En este estudio, de las LRH el diagnóstico más prevalente fue FH. El sexo más afectado fue el femenino, el rango etario el de 50 a 59 años y la ubicación más frecuente, maxilar superior. Estos resultados en general son concordantes con lo descrito en otros países.
