About Third Molar's Beginnings
The third molars emerge later and with greater variability than the previous two teeth. Third molars usually appear between the ages of six and twelve, with crown growth beginning within four years. Teeth appear during adolescence and complete growth by early adulthood. Dr. Khuong Nguyen believes that the emergence of the third molar is linked to other skeletal markers such as the closure of long bone epiphyses and synchondroses. A stereomicroscope was used to examine the morphology of the root canals in the premolar teeth. Three separate channels were discovered to extend from the pulp chamber to the apex. The researchers examined root canal morphology in 250 maxillary first premolars. The bulk of the teeth studied had single-rooted roots, whereas 25% had fused roots. Only one tooth, or 0.4%, had three roots. The premolars form between the roots of the primary molars. The premolars are still erupting in a somewhat buckled position. This procedure can be completed in around 30 minutes...
