A rare case of tooth impaction Kissing Molars associated to dentigerous cyst-Case report

Abstract

Kissing Molars is a term used to describe impacted teeth that contact occlusal surfaces in a single follicular space. The occurrence of this phenomenon is extremely rare and of unknown etiology. Therefore, the present study aimed to present a case report of Kissing Molars associated with dentigerous cyst where a surgical procedure was needed under general anesthesia due to the atrophied jaw. On the left side, of the mandible, and fracture after the removal of the impacted teeth happened and a 2.4 mm reconstruction plate was installed. After the extraction of impacted molars, the lesion with a cystic aspect was removed and sent to histopathological analysis which confirmed the diagnostic hypothesis of dentigerous cyst. Thus, it was concluded that despite the rare impaction and unknown etiology, with a little report in the literature, clinically the case behaves like any impacted tooth, and inflammation may occur if it partially erupts. Radiographically, it presents with the occlusal surfaces in contact and a single follicle, usually associated with the dentigerous cyst.

Conduta e tratamento de cisto dentígero gigante em mandíbula – Relato de caso

“…Segundo a literatura, o cisto dentígero em radiografia evidencia uma imagem com uma área radiolúcida, unilocular e limites bem definidos, circundada por um halo radiopaco esclerótico, em associação à coroa de algum dente impactado. Estas lesões são potencialmente expansivas, podendo revelar em radiografia ou tomografia computadorizada o acometimento da cortical óssea (Ribeiro et al, 2022, Saavedra & Álvarez, 2020Soares et al, 2018). Com o exame deste relato, observou-se área radiolúcida, unilocular com limites bem definidos e circundada por um halo radiopaco envolvendo o elemento 48, em consonância com a literatura.…”

“…(Gomez et al, 2016;Neville et al, 2016). O CD é o tipo de cisto mais comum de se encontrar em pessoas do sexo masculino, cor branca, geralmente dos dez aos trinta anos de idade (Custódio et al, 2021;Ribeiro et al, 2022).…”

“…Como diagnóstico diferencial do cisto dentígero, que possui características clínicas e de imagem em comum com outras patologias como o queratocisto e ameloblastoma unicístico, granuloma central de células gigantes, faz-se necessário realizar o exame histopatológico (Custódio et al, 2021;Gomez et al, 2016;Domingues et al 2018;Ribeiro et al, 2022;Saavedra & Álvarez, 2020).…”

Unilateral case of class 3 kissing molars: A case report

“…More commonly it is smaller and conical in shape [2] . Kissing molars is a rare condition of impacted teeth in which their occlusal surfaces face each other while roots face opposite direction as if teeth are kissing each other [3] . Case of Kissing Molars was first documented by Van Hoof in 1973 in a 31-year-old man.…”

“…Only 32 cases of Kissing molars have been reported since 1973 [4] . Currently only 15 cases of bilateral Kissing molars are reported and the most common teeth involved are second and third molars [3] . In 2012, a Radiologic classification was proposed by Gulses et at, based on teeth that are involved, class 1 involves lower first and lower second molar, class 2 involves lower second and lower third molar, class 3 involves lower third and lower fourth molar [3] .…”
