Also known as TEETH, SUPERNUMERARY

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. The opposite of hyperdontia is hypodontia, where there is a congenital lack of teeth, which is a condition seen more commonly than hyperdontia. The scientific definition of hyperdontia is "any tooth or odontogenic structure that is formed from tooth germ in excess of usual number for any given region of the dental arch." The additional teeth, which may be few or many

Bij hyperdontie, in tegenstelling tot hypodontie, heeft men een of meer tanden te veel. Meestal zien we dit bij de laterale snijtand of bij de verstandskiezen. Professor (Institute of Biotechnology van de Universiteit van Helsinki) toonde aan dat fouten in genen die de botformatie verstoren zodat de fontanellen in de schedel niet sluiten, ook oorzaak zijn van extra tandaanleg. Hyperdontie geeft meestal plaatsgebrek voor de tanden. De behandeling is daarom meestal extractie of chirurgisch verwijderen van het overtollige element. Zeer veel supranummaire (boventallige) tanden blijven ingesloten en komen nooit uit. Veel mensen weten niet dat ze zulk een tand bezitten.
