Hyperdontia is the condition of having supernumerary teeth, or teeth that appear in addition to the regular number of teeth (32 in the average adult). They can appear in any area of the dental arch and can affect any dental organ .
Gardner syndrome can be identified based on oral findings, including multiple impacted and supernumerary teeth, multiple jaw osteomas that give a "cotton-wool" appearance to the jaws, as well as multiple odontomas, congenital hypertrophy of the retinal pigment epithelium (CHRPE), in addition to multiple adenomatous polyps of the colon. Gardner ...
The most frequently involved tooth is the mandibular third molar followed by the maxillary canine, but they may be associated with supernumerary or ectopic tooth. Any permanent tooth can be involved. Regezi and Sciubba [ 6 ] stated that the impacted teeth were most commonly seen in the third molar and maxillary canine teeth, and hence ...
Wisdom teeth (often notated clinically as M3 for third molar) have long been identified as a source of problems and continue to be the most commonly impacted teeth in the human mouth. Impaction of the wisdom teeth results in a risk of periodontal disease and dental cavities. [29] Impacted wisdom teeth lead to pathology in 12% of cases. [30]
Because impacted teeth do not erupt, they are retained throughout the individual's lifetime unless extracted or exposed surgically. Teeth may become impacted because of adjacent teeth, dense overlying bone, excessive soft tissue or a genetic abnormality. Most often, the cause of impaction is inadequate arch length and space in which to erupt.
Similarly, patients present with supernumerary teeth, may have impacted the growth of underlying permanent teeth causing the abnormal root curvature growth. [1] An ankylosed deciduous tooth will not allow for proper growth the permanent tooth. Thus, the tooth may look for another path to erupt.
Impacted wisdom teeth happen when there's not enough room in your mouth for your third molars to emerge and they get stuck under your gum line.
It is possible to have extra, or "supernumerary", teeth. This phenomenon is called hyperdontia and is often erroneously referred to as "a third set of teeth." These teeth may erupt into the mouth or remain impacted in the bone.
