Good retrospective studies from reactive hyperplastic lesions of one’s jaws: examination of 1149 times diagnosed between 2000 and 2011, Chile

The aim of this research were to determine the brand new relative frequency and you can shipments off reactive hyperplastic lesions (RHL) of the oral mucosa on Dental Cystic Institute of College or university of Dental within University out of Chile. New RHL was in fact categorized inside 4 groups: fibrous hyperplasia (FH), pyogenic granuloma (PG), peripheral giant-cellphone granuloma (PGCG) and you will peripheral ossifying fibroma (POF). Results: the most common RHL was FH (71. 1%), with PG (21.1%), PGCG (5 %) and you can POF (2.9%). RHLs was indeed more regular in women (70.7%). More highly affected age group was this new fifty- so you’re able to 59-year-olds (22%). The most typical place for RHL are maxilla (twenty-four.7%), with cheek (20.6%), language (19.4%) and jaw (18.5%). The most prevalent RHL analysis is FH. The absolute most apparently impacted sex is women, the most common a long time is fifty-59 age, as well as the common venue, maxilla.

Los datos de edad y sexo de- los sujetos, y de loca – lizacion y modelo de- lesion, fueron obtenidos del registro de biopsias de- cada caso

El proposito de este estudio fue determinar los angeles frecuencia relativa y distribucion de lesiones reaccionales hiperplasicas (LRH) de- los angeles mucosa oral, presentes durante este registro de biopsias del Servicio de Anatomia Patologica de la Facultad de Odontologia, Universidad de Chile. El estudio, de modelo retrospectivo consistio en 1149 biopsias con diagnostico histopatologico de- LRH, entre los anos 2000- 2011. Las LRH se clasificaron en 5 grupos: Hiperplasia fibrosa (HF), granuloma piogenico (GP), granuloma periferico de celulas gigantes (GPCG) y fibroma osificante periferico (FOP). De las LRH, la lesion mas frecuente fue HF (71,1%), seguido de- GP (21,1%), GPCG (5 %) y FOP (2,nine %) respectivamente. Las biopsias de- LRH fueron mas frecuentes dentro de mujeres (70,eight %). El rango etario mas afectado fue este de- 50 an excellent 59 anos (22%). La localizacion de mayor frecuencia de LRH fue este maxilar advanced (24,7%), seguida de- mejilla (20,6%), lengua (19,4%), mandibula (18,5%), labio substandard (nine,9%) y labio advanced (six,7%). Durante este estudio, de las LRH el diagnostico mas prevalente fue FH. Estos resultados en standard child concordantes scam lo descrito dentro de otros paises.

El sexo mas afectado fue el femenino, el rango etario el de fifty an effective 59 anos y los angeles ubicacion mas frecuente, maxilar superior

Reactive hyperplastic lesions (RHL) is several stringy modifications of your own conjunctive tissue. They often can be found in the fresh oral mucosa in response so you’re able to injuries1 eg regional persistent annoyances otherwise shock due to the presence off brick, remodeling that have unpredictable edges, low-levels traumatism and you will iatrogenic facts. The fresh mucosa reacts to those irritant things which have local hyperplasia composed stay at website out-of mature collagen, fibroblasts, mineralized muscle, endothelial structure and you may giant multinucleated structure. These types of lesions commonly felt neoplasms, but inflammatory hyperplastic responses 2 . The brand new acknowledged category away from dental mucosa RHL comes with a wide range regarding lesions 2 , as well as fibrous hyperplasia (FH), pyogenic granuloma (PG), fibrous epulis having ossification otherwise peripheral ossifying fibroma (POF) and you may peripheral icon-mobile granuloma (PGCG). The fresh systematic and histopathological services of every are demonstrated less than.

FH is actually a powerful bulk, easy, nodular, which have a delicate body and you may normal color that may appear within any location of the oral mucosa. Histologically, it is including conjunctive cells having thicker collagen 2,3 . PG seems medically because a keen erythematous size, pain-free, smooth, lobulated, fast-increasing and you will hemorrhaging without difficulty when touched. It is of this traumatization, worst dental health and increase inside hormone membership in pregnancy. It generally appears on the nicotine gum and in addition in reduced usual locations including the throat, language and you will dental mucosa step three . Histologically, it is including hyperplastic granulation cells having reasonable proliferation out-of endothelial structure within the capillary avenues and you may an enthusiastic infiltrate away from blended inflammatory structure 2 . POF seems just on the chewing gum, while it began with the latest periodontal tendon.
