Radicular Cyst in Deciduous Maxillary Molars: A Rarity

Abstract

Radicular cyst arising from deciduous teeth is exceedingly rare accounting for <1% of all radicular cysts. A total of 122 cases have been reported to date in the English language literature. We present a rare case of a radicular cyst associated with a decayed deciduous maxillary molar tooth without any history of prior pulp therapy. Our aim is to emphasize the recognition of inflammatory radicular lesions associated with deciduous teeth which may adversely impact underlying permanent successor.

Radicular cyst in mixed dentition

“…Radicular cysts are the most frequent inflammatory odontogenic cysts of the jaw with a peak frequency in the periapical radiolucency in relation to primary teeth are usually neglected or not submitted to histopathological examination [1,4,5].…”

“…Radicular cysts are the most frequent inflammatory odontogenic cysts arising from epithelial residues in primary and/or permanent tooth-bearing areas [1]. The frequency of radicular cysts in permanent dentition is approximately 52-68 % [2,3], while in primary dentition the frequency is approximately 0.5-3.3 % of the total number of radicular cysts in both primary and permanent dentition [3,4].…”

“…The frequency of radicular cysts in permanent dentition is approximately 52-68 % [2,3], while in primary dentition the frequency is approximately 0.5-3.3 % of the total number of radicular cysts in both primary and permanent dentition [3,4]. Radicular cysts associated with deciduous teeth were frequently reported in the age range of 3-19 years with a male predominance and commonly associated deciduous teeth are mandibular molars followed by maxillary molars and anterior teeth [1,6].…”

“…The common etiological factors for the development of radicular cysts in primary dentition are dental caries followed by trauma [1,5,6]. Initially radicular cysts are asymptomatic and are discovered when periapical radiographs are taken [2,7] and it is often quoted that radicular cysts are painless unless infected [2].…”

“…Initially radicular cysts are asymptomatic and are discovered when periapical radiographs are taken [2,7] and it is often quoted that radicular cysts are painless unless infected [2]. Radicular cysts are associated with the apex of the tooth and a diameter of at least 1 cm is postulated to be necessary to differentiate them from that of a normal follicular space [8]; however, the formation in mixed dentition may cause local alterations, therefore, management is crucial [1,6]. The aim of this case report is to present an additional case of a radicular cyst associated with deciduous mandibular molar showing some unique features.…”
