Calssification of traumatic dental injuries...with 2 dental injuries lecture notes.


There are numerous classification systems currently available for TDI (Table 1).  Andreasen’s classification is a modification of the World Health Organization’s (WHO) and contains 19 groups that include injuries to the teeth, supporting structures, gingiva and oral mucosa. Unlike the WHO classification, the socket and fractures of the mandible or maxilla are not grouped under oral injuries, but rather are classified separately as fractures of face bones. It is a very comprehensive system which allows for minimal subjective interpretations .
The WHO classification of oral trauma describes injuries to the internal structures of the mouth and incorporates of a broad group “other injuries including laceration of oral soft tissues”. García-Godoy’s classification is also a modification of the WHO system. This classification differs from others mainly because it separates dental fractures into those which involve cementum and those which do not. Moreover, there are no groupings for subluxation or alveolar injuries and mandible or maxilla fractures.
The Ellis classification is another modification of the WHO system. This system is a simplified classification which groups many injuries and allows for subjective interpretation by including broad terms such as “simple” or “extensive” fractures. Injuries to the alveolar socket and fractures of the mandible and maxilla are not classified here.

  2. Please I had a dentist pull a tooth and the root broke off in the top of my mouth and it has been there for 2 years rotting it and now my body is rejecting it and it is popping through my gum and pushing it to another tooth

  3. I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the
    liver already present. I started on antiviral medications which
    reduced the viral load initially. After a couple of years the virus
    became resistant. I started on HEPATITIS B Herbal treatment from
    ULTIMATE LIFE CLINIC ( in March, 2020. Their
    treatment totally reversed the virus. I did another blood test after
    the 6 months long treatment and tested negative to the virus. Amazing
    treatment! This treatment is a breakthrough for all HBV carriers.
