We report the diagnosis and successful clinical management of three patients with anatomical variation in the maxillary first premolars. Maxillary first premolars have highly variable root canal morphology, but the presence of three canals is rare. This article describes the diagnosis and clinical management of first maxillary premolars with three canals and three separate roots, with special r...

Maxillary tuberosity fractures during molar teeth extraction can occur commonly in dental practice; however, very few cases are reported and discussed in the literature. This article presents a case of large fracture of maxillary tuberosity during extraction of first maxillary molar tooth and its conservative treatment outcomes.

In 1976 Rappaport et al. introduced the term Monosuperocentroincisivodontic dwarfism to describe patients who exhibit a solitary maxillary central incisor in both dentitions in conjunction with growth retardation.1 The frequency of congenitally missing maxillary primary central incisors has not been reported, but the frequency of congenitally missing maxillary permanent central incisors is rare...

Although most of the maxillary sinus retention cysts are asymptomatic, a few of them increase in size and cause symptoms. However, they rarely erode bony walls nor protrude into the inferior meatus. I present 2 cases with maxillary sinus retention cysts protruding into the inferior meatus by making a large defect on the medial wall of the maxillary sinus.

A patient with chronic unilateral maxillary sinusitis caused by a foreign body (dental amalgam) and mistaken diagnosis of extensive ethmoid neoplasm is presented. The imitation of tumour symptoms was due to a long presence of foreign body in the maxillary sinus and chronic inflammation of maxillary, ethmoid and sphenoid sinuses.

Maxillary sinus harbours many pathological lesions. Many of those presents as a sinonasal mass and are rarely symptomatic. These masses are usually an antral polyp, mucoceles or mucous retention cysts. Odontogenic keratocyst, a benign odontogenic lesion presenting within the maxillary sinus is a rare entity. We present a case of odontogenic keratocyst of the maxillary sinus in a 35 years old fe...
