Abstract
ABSTRACT Objective: In the literature, some studies show a relation between tooth agenesis and craniofacial morphology, whereas other authors conclude that dental agenesis exerts little influence on dent facial structures. The objective of this study was to determine the existence of any relation between bilateral agenesis of the maxillary and/or mandibular third molars and the anteroposterior dimensions and vertical growth pattern of the jaws. Subjects and Methods: Sixty-eight subjects between the ages of 13 and 17 years with bilateral agenesis of maxillary third molars (group I, n=37), bilateral agenesis of the mandibular third molars (group II, n=19), and agenesis of all third molars (group III, n=12) as well as 33 subjects without third molar agenesis (group IV) were selected from the radiology archive. A before and after treatment orthopantomograph and the pretreatment cephalometric radiograph of the subjects were used. Several angular and linear parameters representing the anteroposterior dimensions...
