This case report explains non-surgical endodontic treatment of a mandibular second premolar with three separate roots and three separa...
a mandibular second premolar with four canals is an interesting example of anatomic variations. this report describes a case of a mandibular second premolar with three roots and four canals (one mesiobuccal, two distobuccal and one lingual). the canals were prepared using k-files and irrigated with naocl (5.25%) and normal saline as the final irrigant. the canals were filled laterally with gutt...

Ankylosis of primary mandibular molars has been routinely found to be associated with various developmental disturbances in permanent dentition such as aplasia of the succedaneous tooth, ectopic eruption of the premolar, infraoclusion of the ankylosed tooth leading to tipping of the first permanent molar etc. This article describes a rare case where there was ankylosis of a mandibular second pr...
A lateral periodontal cyst (LPC) is a rare finding. Patients diagnosed with LPC younger than 40 years of age are not that common. Mostly asymptomatic LPCs can be discovered on routine radiographs as an oval radiolucency between two mandibular premolar teeth roots and vary in shape size.
