Hypodontia - Prevalence

Prevalence

In caucasians, the most common missing teeth are the wisdom teeth (25-35%), the upper lateral incisors (2%) the lower second premolars (3%), or the upper second premolar, with a 4:1 female to male ratio. The prevalence of missing primary teeth is found at 0.1-0.9%, with a 1:1 male to female ratio. Excluding the third molars, missing permanent dentition accounts for 3.5-6.5%. Similar trends of missing teeth can be seen in approximately 3-10% of orthodontic patients.

30-50% of people with missing primary teeth will have missing permanent teeth, as well.

Famous quotes containing the word prevalence:

    The prevalence of suicide, without doubt, is a test of height in civilization; it means that the population is winding up its nervous and intellectual system to the utmost point of tension and that sometimes it snaps.
    Havelock Ellis (1859–1939)

    That the public can grow accustomed to any face is proved by the increasing prevalence of Keith’s ruined physiognomy on TV documentaries and chat shows, as familiar and homely a horror as Grandpa in The Munsters.
    Philip Norman, British author, journalist. The Life and Good Times of the Rolling Stones, introduction (1989)
