Radicular cysts are slow growing and are the most common odontogenic cystic lesions of inflammatory origin affecting the jaws. Most radicular cysts are small, but they can reach a large size. Sometimes, the cyst may cause displacement of surrounding structures. The purpose of this article is to report the case of a large radicular cyst that had displaced the floor of the maxillary sinus and treated by enucleation along with apicectomy and antrostomy.

Adenomatoid odontogenic tumor (AOT) was first described by Steinmann in 1905. It is a relatively rare benign odontogenic tumour accounting for 3% of all odontogenic tumours [1]. Philpsen coined the term – Adenomatoid odontogenic tumour. It has distinct clinicopathological appearance but often misdiagnosed as cyst. In this paper, we present a case series of 16 cases in different locations of maxilla and mandible.

The bone loss following an extraction is inevitable. The buccopalatal collapse due to horizontal and vertical bone loss can cause unesthetic appearance following a prosthesis on a long run. The partial extraction therapy involves a group of procedures to preserve buccopalatal bone thereby preserving the bone and improving esthetic.
