The lamina dura is a healthy structural component in teeth. This study highlights the association of bone formation with disruption of lamina dura below the crown of the mandibular horizontal incompletely impacted third molar.

BACKGROUND Third molars are the most commonly impacted teeth, and their extraction is the most commonly performed procedure in oral and maxillofacial surgery. The aim of the present study is to describe the pattern of mandibular third molar impaction and to define the most appropriate age for prophylactic extraction of mandibular third molar teeth. METHODS A total of 1198 orthopantomographs (...

Impacted mandibular third molars can be located in close proximity to the mandibular canal. This creates a risk for the nerve or artery injury. These are contained in the canal. However, the impacted third molar can be moved coronally by orthodontic means, after removal of overlying bone, and safely extracted. The orthodontic intervention slowly moves the tooth apex away from the mandibular can...

background and aims. a through knowledge of the root canal morphology is required for successful endodontic therapy. the aim of this study was to investigate the root and canal morphology of mandibular third molars in kerman, a province in southeast of iran. materials and methods. one-hundred-fifty extracted mandibular third molars were collected randomly from different dental clinics in kerman...

Background: Third molars are the most frequently impacted teeth, and extensive research has been carried out delineating their impaction prevalence, classification, and treatment approaches. We present a rare case of an impacted mandibular third molar which went through unprecedented changes in angulation over an eight-year time span with no particular pathologic, traumatic, or therapeutic inte...

OBJECTIVE To determine the prevalence of impacted mandibular second molar (MM2) and the association between MM2 impaction and crowding. The clinical significance of the angle between first and second mandibular molar and of the space between the first mandibular molar (MM1) and the anterior margin of mandibular ramus in MM2 impaction were also evaluated. MATERIAL AND METHODS In this retrospec...
