Association between third molar agenesis and craniofacial structure development

2015

Introduction The aim of this investigation was to study the relationship between third molar agenesis—including the number of ageneses—and craniofacial structure growth. Methods We reviewed 305 clinical histories of patients treated at the Orthodontics Unit of the Faculty of Medicine and Dentistry at the University of Valencia in Spain.
