Содержание слайда: Whenever a calcified tooth does not erupt, it is a case of incarceration or impaction according to whether the path leading to normal position in the arch is free or obstructed. This abnormality affects the third molars, upper and lower, the upper second bicuspids, the upper laterals and upper and lower cuspids with greater frequency than other teeth. Incarceration of a permanent tooth is sometimes associated with the retention of the corresponding deciduous tooth until later in life than normal, and occasionally even throughout the life of the individual.

Содержание слайда: The influence of heredity in these abnormalities of number is well shown in the case of the upper laterals, this tooth being sometimes absent through several generations, in one or several members of the same family.
The influence of heredity in these abnormalities of number is well shown in the case of the upper laterals, this tooth being sometimes absent through several generations, in one or several members of the same family.
The absence of the complete dentition, both deciduous and permanent and of the permanent alone, is an extremely rare occurrence, nevertheless cases of this kind are on record in dental literature.

Содержание слайда: The absence of the permanent upper right lateral incisor is a rather frequent abnormality. The absence of a lower incisor is a rare abnormality. A lower bicuspid may be absent and when it fails to erupt it is the second more frequently than the first. The permanent first molar may be absent owing to the failure of the fully calcified tooth to erupt, its presence in the substance of the jaw being made evident with the aid of radiography. The absence of the permanent cuspids is rarely the result of the non-development of the tooth, but in most instances is due to the failure of the fully formed tooth to erupt.

Содержание слайда: The absence of deciduous teeth is occasionally observed. The absence of teeth from the arch should be diagnosed invariably with the aid of carefully secured radiograms. Unquestionably, many cases of absence of teeth are cases of non-eruption or incarceration of fully calcified teeth, which remained within the substance of the jaws; in some cases this incarceration does not cause any apparent discomfort to the patient, while in others it produces reflex manifestations of varying degrees of intensity.
