Second Premolar Extraction: A Case Report
To correct the malocclusion is the chief aim of an orthodontist. For each individual, ideal facial esthetics would result when the teeth were placed in ideal occlusion. Malocclusion is caused by two ways either spacing or crowding in which crowding is the most common cause.Treatment of a crowded arch requires space gaining. This has been achieved through two ways of treatment – extraction or no...
متن کاملMandibular Second Premolar with Three Roots: A Case Report
Human mandibular premolars have earned the reputation for having an extremely complex root and root canal morphology. The incidence of multiple roots and canals in mandibular second premolars is lower than those in mandibular first premolars. Mandibular second premolars with three root canals and separate foramina are very rare. In this case report, endodontic management of a three-rooted mandi...
متن کاملMandibular Second Premolar with Four Canals
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...
متن کاملFirst or second premolar extraction effects on facial vertical dimension.
If the concept of mesial movement of molars to reduce the "wedge effect" and decrease facial vertical dimension (FVD) is valid, it is important to investigate the effect of first (P1) and second premolar (P2) extraction on FVD. This study compares the mesial movement of molars and changes in FVD between P1 and P2 extraction groups in Class I malocclusion with a hyperdivergent facial type. We co...
متن کاملAgenesis of Mandibular Second Premolar
Tooth agenesis is the most common of all dental developmental disorders. The mandibular second premolars are the teeth most commonly found missing (2.2 to 4.1%) after the third molars. There are more studies on tooth agenesis than the other malformations but yet they are limited. This article reviews the studies related to agenesis of mandibular second premolars and the underlying mechanisms be...
