Abstract:
Mandibular canine impaction is an uncommon eruption disturbance, and its relationship with craniofacial asymmetry in adolescents is not well established. This study evaluated the correlation between craniofacial asymmetry and unilateral mandibular canine impaction in 60 adolescents (12-18 years), including 30 impaction cases and 30 matched controls. Lateral and posteroanterior cephalograms were used to assess mandibular midline deviation, ramal height asymmetry, mandibular body length difference, and gonial angle discrepancy. Intergroup comparisons were performed using independent sample t-tests, and associations were analyzed using Pearson correlation (p < 0.05). Significantly higher asymmetry values were observed in the impaction group, with mandibular midline deviation and body length discrepancy showing the strongest correlation, indicating asymmetry as a potential predictor for eruption disturbances.

The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
