Primary Canine Tooth: Structure And Functional Insights

Primary Canine Tooth: Structure And Functional Insights

Describe the Primary Maxillary Canine.
Answer:

• Labial aspect.
• Constricted crown at the cervix.
• Mesial and distal surfaces are more convex.
• The incisal edge has a long, well-developed, sharp cusp.
• Mesial slope of the cusp is longer than the distal slope of the cusp.
• A line drawn through the contact areas of the deciduous canine would bisect a line drawn from the cervix to the tip of the cusp.

Primary Maxillary Canine Lingual aspect:

• It shows pronounced enamel ridges that merge with each other.
• It shows cingulum, mesial and distal marginal ridges, incisal cusp ridges, lingual ridge, and tubercle at the cusp tip.
• The lingual ridge divides the lingual surface into shallow mesiolingual and distolingual fossae the root of this tooth tapers lingually.

Primary Maxillary Canine Mesial aspect:

• The labiolingual measurement at the cervical third is much greater.
• It permits resistance against forces the tooth must withstand during function.
• The function of this tooth is to punch tear and apprehend food material.

Primary Maxillary Canine Distal aspect:

• The curvature of the cervical line toward the cusp ridge is less than the mesial surface.

Primary Maxillary Canine Incisal aspect:

• The Crown is diamond-shaped.
• Has more pronounced and less rounded lines and point angles.
• The tip of the cusp is distal to the center of the crown.
• The mesial cusp slope is longer than the distal cusp slope.
• This allows for intercuspation with the mandibular canine which has its longest slope distally.
