Spontaneous Eruption of Premolar Associated with a Dentigerous Cyst

Abstract

Dentigerous cyst (DC) is the second most common odontogenic cyst with greater incidence in young patients. It presents as a unilocular, asymptomatic radiolucency involving the crown of an impacted tooth, commonly noticed in X-rays to investigate absence, wrong tooth position, or delay in the chronology of eruption. Decompression/marsupialization (D/M) is the most implemented treatment, especially when preserving the tooth involved is advised. The aim of this study is to discuss the DC characteristics that contribute to spontaneous eruption of premolars, by reporting the case of a conservative treatment of DC. This eruption depends on factors such as age, angulation of inclusion, rate of root formation, depth of inclusion, and eruption space. This paper reports the case of a 10-year-old patient with a radiolucent lesion diagnosed as DC involving element 35, which erupted as a result of treatment. The patient was observed during 1 year and 6 months.

Five Years Follow-up of a Spontaneous Eruption of an Impacted Mandibular Premolar Associated with a Dentigerous Cyst Treated by Marsupialization

“…The treatment of choice of DC is the enucleation and the removal of the affected tooth; in the case of large cysts, an initial phase of marsupialization followed by the total enucleation is recommended. If DC is connected with a canine or a premolar with a positive eruptive position, marsupialization is preferred [2][3][10][11]12,14].…”

“…Treatment modalities of DC are enucleation and decompression/marsupialization; however, despite the favorable prognosis of DC whatever the surgical technique is, some important factors must be considered for the treatment plan, such as DC size and proximity to anatomic structures, the patient's age, and the possibility of saving the involved tooth [2,6,[10][11][12]. Therefore, marsupialization in pediatric dentistry was preferred based on the higher tooth eruption potential in children with teeth open apices [12][13].…”

Clinical and Histopathological Study of Dentigerous Cyst Associated to Maxilar Lateral Tooth: Case Report

“…Se forma entre el epitelio del esmalte y el esmalte de la corona de un diente en proceso de erupción, no erupcionado o incluído, con acumulación de líquido en esta zona (4,(5)(6)(7)(8)(9)(10)(11)(12). En ocasiones puede estar asociado a odontomas o supernumerarios representando un 5% de todos los quistes dentígeros (13,14,15).…”

“…En ocasiones puede estar asociado a odontomas o supernumerarios representando un 5% de todos los quistes dentígeros (13,14,15). Su localización más frecuente es en región mandibular de terceras molares, seguidos de canino maxilar y segundo premolar maxilar (1)(2)(3)(4)(5)(6)(7). La edad promedio de aparición es entre la segunda y tercera década de la vida (1,19).…”

“…A menudo no presentan sintomatología, generalmente es observado de manera casual en radiografías panorámicas que evalúan estadío de erupción. Radiográficamente se observa como una lesión radiolúcida unilocular de borde esclerótico con forma curvada o circular asociado a corona de un diente no erupcionado que expande corticales externas (3,4,6,7,15). Algunos QD se desarrollan de forma excéntrica desde lateral del folículo, ocupando un área al lado de la corona y no encima de ella (9,11,12).…”
