Agenesis 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...
متن کاملAgenesis of mandibular second premolar in patient with dental bimaxillary protrusion
The present study reports the treatment carried out in a patient with mandibular second premolar agenesis associated with early loss of a deciduous second molar, deep overbite, severe overjet and dentoalveolar bimaxillary protrusion, which led to lip incompetence and a convex facial profile. The main objectives of this treatment were: to eliminate the spaces in mandibular arch, correct overbite...
متن کاملPredicting Agenesis of the Mandibular Second Premolar from Adjacent Teeth
Early diagnosis of agenesis of the mandibular second premolar (P2) enhances management of the dental arch in the growing child. The aim of this study was to explore the relationship in the development of the mandibular first molar (M1) and first premolar (P1) at early stages of P2 (second premolar). Specifically, we ask if the likelihood of P2 agenesis can be predicted from adjacent developing ...
متن کاملThe Association Between Dental Anomalies and Hypodontia Among 9-20 years Old Individuals in Ardabil City, Iran: A Causal-Comparative Study
Introduction: This study aimed to investigate the relationship between the prevalence of dental anomalies and hypodontia. Materials and Methods: In this retrospective study, the panoramic radiographs of 101 cases with tooth agenesis (except for the third molar) were studied and compared with [Pn1] those of a non-agenesis control group of 182 subjects. The subjects were within the age range of ...
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...
