Practice Question # 104.

Maxillary versus Mandibular

• Maxillary canines display greater mesiodistal width than mandibular canines in both deciduous and permanent dentition.

• The maxillary cingulum (bulge on the lingual surface near the cervical region of the tooth) is more substantial than the mandibular cingulum (particularly in the permanent canines).
• A maxillary canine usually displays a central strengthening ridge extending from the cingulum to the cusp.
• The mandibular canine does not display a central lingual ridge, thus the lingual surface is flatter.
• The maxillary canine root is the longest and strongest of the whole dentition.
• The mandibular canine root is flattened and grooved distally.
