Abstract

ABSTRACT Dentigerous cyst, ranked the second most common developmental odontogenic cyst of the jaws after the radicular cyst, is a well-defined, unilocular radiolucent lesion without symptoms, frequently noted as an incidental finding in routine radiographs. The cystic lining is derived from epithelial remanants of the tooth-forming organ and the teeth most commonly affected are impacted mandibular third molars and permanent maxillary canines. While the dentigerous cyst is not uncommon, its development as a result of an impacted deciduous tooth is rare. The aim of this article was to make a brief literature review and report a case of dentigerous cysts associated with an impacted deciduous molar in the maxillary posterior region, with involvement of the right maxillary sinus.

Highlights

Among the developmental cysts in the maxillofacial region, the dentigerous cyst is ranked the second most common after the radicular cyst [1,2,3]
The cystic content is derived from epithelial remnants of the toothforming organ and the teeth most commonly affected are impacted mandibular third molars and permanent maxillary canines, mandibular premolars, followed by supernumerary teeth and central incisors, in decreasing frequency of involvement [5,6,7]
The development of a dentigerous cyst in association with impacted permanent teeth is not uncommon, whereas, its development as the result of noneruption of deciduous teeth is rare Yamanaka et al [9], Kishimoto et al [12], Kusukawa et al [13], Rosenlicht et al [14], Bharath et al [15]. This coincides with this report and that of Michael et al [10], who reported a study, of a dentigerous cysts that developed as a radiolucent lesion associated with an impacted maxillary deciduous molar, which emphasizes the relevance and rarity of this article

Summary

Introduction

Among the developmental cysts in the maxillofacial region, the dentigerous cyst is ranked the second most common after the radicular cyst [1,2,3]. The term dentigerous means “containing a tooth”, and this is the characteristic description of this cyst [4]. Teeth in a mesial position are occasionally reported in approximately 5% of all dentigerous cysts [8]. The occurrence of a dentigerous cyst associated with a deciduous tooth is a rare phenomenon [9,10,11,12,13,14]. The majority of patients with dentigerous cysts present no painful symptomatology, unless there is an exacerbated inflammatory process.
