Such tooth avulsion was the intentional removal of one or more teeth, which was done for ritual or aesthetic reasons. It was also used to denote group affiliation. Typically, the maxillary incisors were the teeth most often selected for removal. This practice is still common in parts of Africa. [48]
There are 32 permanent teeth and those of the maxillae (on the top) erupt in a different order from permanent mandibular (on the bottom) teeth. Maxillary teeth typically erupt in the following order: (1) first molar (2) central incisor, (3) lateral incisor, (4) first premolar, (5) second premolar, (6) canine, (7) second molar, and (8) third molar.
[vague] [6] Talon cusp tends to occur on permanent teeth only, [5] being very rare in deciduous teeth. [5] In most cases, the involved teeth are the permanent maxillary lateral incisors (55%), followed by maxillary central incisors (33%), mandibular incisors (6%), and maxillary canines (4%).
Talon cusps range from less than 1% to 6% of the population, and 33% of cases occur on the permanent maxillary central incisor. [19] Deciduous teeth are unlikely to have talon cusps. Also, the permanent maxillary incisors are the most likely teeth to have a dilaceration, which is a sharp curve on a tooth. [20]
Mamelons are present on permanent central and lateral incisors. Mamelons are easiest to observe on the maxillary central incisors, and appear as three small prominences on the incisal edge of the tooth. [2] Mamelons are ordinarily of no clinical importance. [3] Usually, they are worn off early in the life of the tooth. [medical citation needed]
The mandibular anterior teeth must be stabilized to prevent excessive lingual tipping. A fixed mandibular arch from the left first permanent molar to the right first permanent molar may be required. Judicious reproximation disking of primary teeth with no tooth extraction is an occasional option.
As growth of the alveolar bone continues and the adjacent permanent teeth erupt, the ankylosed deciduous tooth appears to submerge into the bone, although in reality it has not changed position. Treatment is by extraction of the involved tooth, to prevent malocclusion, periodontal disturbance or dental caries. [3]
Permanent teeth or adult teeth are the second set of teeth formed in diphyodont mammals.In humans and old world simians, there are thirty-two permanent teeth, consisting of six maxillary and six mandibular molars, four maxillary and four mandibular premolars, two maxillary and two mandibular canines, four maxillary and four mandibular incisors.
