Permanent teethoradult teethare the second set ofteethformed indiphyodontmammals.In humans and old world simians, there are thirty-two permanent teeth, consisting of sixmaxillaryand sixmandibularmolars,four maxillary and four mandibularpremolars,two maxillary and two mandibularcanines,four maxillary and four mandibularincisors.[1]
Timeline
[edit]The first permanent tooth usually appears in themouthat around 5-6 years of age, and the mouth will then be in a transition time with both primary (ordeciduous dentition) teeth and permanent teeth during the mixed dentition period until the last primary tooth is lost or shed.[2]
The first of the permanent teeth to erupt are the permanent first molars, right behind the last 'milk' molars of the primary dentition. These first permanent molars are important for the correct development of a permanent dentition. Up to thirteen years of age, 28 of the 32 permanent teeth will appear.
The full permanent dentition is completed much later during the permanent dentition period.[3]The four last permanent teeth, the third molars, usually appear between the ages of 17 and 21 years; they are consideredwisdom teeth.[4]
Pathology
[edit]It is possible to have extra, or "supernumerary", teeth. This phenomenon is calledhyperdontiaand is often erroneously referred to as "a third set of teeth." These teeth may erupt into the mouth or remain impacted in the bone. Hyperdontia is often associated with syndromes such ascleft lip and cleft palate,tricho-rhino-phalangeal syndrome,cleidocranial dysplasia,andGardner's syndrome.[5]
