Management and Development of Canines

These flashcards cover the key concepts and important details related to the development, displacement, and management of canines as discussed in the lecture.

What age does the development of the maxillary canine commence?

Around 4–5 months of age.

At what age is crown calcification of the permanent canine completed?

Around 6–7 years of age.

What is the average eruption age for upper canines?

11–12 years of age.

What percentage of a Caucasian population experiences congenital absence of upper canines?

0.3%.

What is the percentage of congenital absence for lower canines in Caucasian populations?

0.1%.

What percentage of palatally displaced canines occurs with absent or short-rooted lateral incisors?

2.4-fold increase.

How is canine displacement classified?

Generally classified into buccal or palatal displacement.

What is the incidence of impaction for upper canines?

1–2%.

What is the prevalence of transposition in canines?

0.33%.

What is suggested as a causative factor for canine displacement?

Displacement of the crypt.

What is a common association with buccally displaced canines?

About 85% are associated with crowding.

At what age should children be routinely palpated for unerupted canines?

Aged 10 years and older.

What diagnostic tool can be used to demonstrate asymmetry in canine position?

Panoramic radiographic examination.

What factors are involved in the assessment of maxillary canine position?

Palpation and radiographic examination.

What is the purpose of radiographic assessment for canine positioning?

To determine the location of the canine crown and root apex relative to adjacent teeth.

What technique is used for vertical parallax in radiographic assessment?

An upper anterior occlusal radiograph.

What may be indicated if the crown of a buccally displaced canine is below the mucogingival junction?

An open procedure to expose the crown.

Which tooth is most associated with transposition anomalies?

The canine tooth.

What is a possible treatment option for transposition of canines?

Extraction of the most displaced tooth if the arch is crowded.

What usually occurs if severe root resorption is present in adjacent teeth?

Extraction of the affected incisor(s) may be necessary.
