Large Radicular Cyst of The Posterior Maxilla - A Case Report.

Radicular cyst is the most common inflammatory odontogenic cystic lesion of the jaws. It usually originates as sequel to a periapical inflammatory process, following chemical, physical or bacterial injury. Due to its chronic etiology, the cyst usually appears in the later stages of life. It has a male sex predilection, with the maxillary anterior region as the most common site of involvement. This article describes an unusual case of a large radicular cyst in the posterior maxilla along with its management and follow-up.

Eruption Cyst : A Case Report.

The eruption cyst is regarded as a soft tissue analogue of the dentigerous cyst, but is considered as a distinct clinical entity. It is defined as a cyst that lies superficial to the crown of an erupting tooth, and is lined by stratified squamous non-keratinizing epithelium. Clinically, it appears as a soft, often translucent swelling of the gingival mucosa overlying the crown of the involved tooth, and may vary from pink to bluish-purple in colour. It is usually seen in children and the teeth commonly affected include the permanent first molars and maxillary incisors. Radiographically, no evidence of bone involvement is seen and treatment consists of simple excision of the roof of the cyst. This paper describes a case of an eruption cyst in a 7-year old male patient, which presented as a swelling involving the gingiva overlying the crown of 21, along with a review of the literature.
