An inflammatory Odontogenic Cyst (Unusual Case)

Different types of inflammatory lesions, such as odontogenic cysts, can affect the oral and maxillofacial regions. The conventional aetiology of inflammatory periapical lesions is triggered by dental caries or traumatic injury to the teeth, leading to the death of the dental pulp and subsequent bacterial infiltration of the periapical area. In rare cases, inflammatory odontogenic cysts may originate from non-inflammatory causes, such as the presence of enamel pearls located within the furcation of teeth with multiple roots. This case report illustrates a case of an asymptomatic inflammatory cyst associated with the upper left first molar in a young female patient. The cyst developed without any obvious clinical explanation and appeared in a typical sound tooth without evidence of pathology-related conditions. The radiographic findings demonstrated a notably aggressive nature not atypical for inflammatory cysts. The cyst expansion resulted in significant displacement of the adjacent upper left second molar, causing it to deviate from its original position within the dental arch. Additionally, the inferior border of the maxillary sinus was displaced in a superior direction. The diagnosis of non-specific inflammatory cyst was confirmed via histopathological examination. In this particular case, it is important to acknowledge that no singular factor is attributed to the cyst development. However, it is worth noting that the tooth in question is associated with enamel pearls, which have been discussed in the field of oral and maxillofacial pathology as a relatively uncommon cause of inflammatory cyst development.
