Eruption cysts: a clinical report of 24 new cases

Abstract

The eruption cyst (EC) occurs within the mucosa overlying a tooth that is about to erupt. In the past EC was considered a type of dentigerous cyst (DC) occuring in the soft tissues. Twenty four patients (mean age 4.44 years, range 1.0 month - 12 years) with EC were diagnosed and treated. EC was associated with natal teeth in two (8.3%) cases, with primary teeth in 10 (41.6%) cases and with permanent teeth in 12 (50%) cases. There was a gender predilection, the male to female ratio was 2:1. The primary mandibular central incisors and the permanent first molars were the most common site affected. The clinical appearance was a raised, bluish gingival mass on the alveolar ridge. The size was variable and dependent on the size and number of the associated teeth. The type of treatment provided was one of the following: no treatment (10 cases, 42%), extraction (2 cases, 8%) and marsupialization (12 cases, 50%). All surgical specimens underwent histopathologic examination. EC should be recognized as a separate entity from DC and a conservative treatment approach is recommended.

Odontogenic Cysts: Analysis of 680 Cases in Brazil

“…In agreement with our findings, studies in the literature report a frequency of 0.1-1% of all odontogenic cysts [2][3][4][5]. According to the literature, the maxilla [3,[20][21][22] and men [2,5,21,23] are most frequently affected. They occur in the first decade of life [5,21,23] and in white individuals [21,22] most frequently.…”

They occur in the first decade of life [5,21,23] and in white individuals [21,22] most frequently. Only one case was found in our study: a cyst associated with tooth #21 in an 8-year-old white boy.…”

Hematomas de erupção: relato de três casos clínicos em bebês

“…A ocorrência nos casos registrados neste estudo foi de 2:1 com relação ao sexo, dois meninos para uma menina, assim como a literatura aponta 8 . A importância de relatar esses casos está na baixa prevalência dos cistos de erupção na dentição decídua.…”

“…Assim, se houver um traumatismo na superfície dos cistos, levando à presença de sangue no interior da cavidade cística, eles apresentarão uma coloração purpúrea, sendo então chamados de hematomas de erupção 7 . Essa patologia é mais comum na dentição permanente e em meninos 8 , sendo considerada rara em associação com dentes decíduos, com um acometimento de aproximadamente 0,7% 5,9 . Normalmente, na dentição decídua não há indicação de tratamento, apenas o acompanhamento, pois em geral a lesão rompe e o dente irrompe na cavidade bucal.…”

Congenital eruption cyst: a case report

“…Although most EC reports are in the first decade of life, only a few reports have shown this type of lesion in neonates (3)(4)(5). This paper presents a case of congenital EC successfully managed by close monitoring of the lesion, without any surgical procedure or tooth extraction.…”
