GANGGUAN ERUPSI MOLAR-3

The English wisdomtooth is derived from Latin dens sapientiae. The same root is shared by German Weisheitszahn, Dutch verstandskies, Afrikaans verstandtand, Belgian-Dutch wijsheidstand, Norwegian visdomstann, Danish and Swedish visdomstand, Finnish viisaudenhammas, French dent de sagesse, Portuguese dente siso or dente do juzo, Spanish muela del juicio or muela cordal, Italian dente del giudizio, Romanian msea de minte, Slovenian modrostni zob, Croatian and Serbian umnjaci, Hungarian blcsessgfog, Czech zuby moudrosti, Polish zby mdroci, Russian , Bulgarian (meaning wise man), Estonian tarkusehammas, Lithuanian protiniai dantys, Hebrew (shen bina) and Greek (fronheemeetes). Turkish refers directly to the age at which wisdom teeth appear and calls it 20 ya dii (20th year tooth). In Arabic, its name is Ders-al-a'qel ( ), literally meaning "The tooth of the mind" and hence similar to occidental names. In Korean, its name is Sa-rang-nee (, love teeth) referring to the young age and the pain of the first love. In Japanese, its name is Oyashirazu (), literally meaning "unknown to the parents," from the idea that they erupt after a child has moved away. The Indonesian term gigi bungsu for the latest teeth a person cuts refers to bungsu "youngest child". In Thailand the wisdom tooth is described fan-khut () "huddling tooth" due to its shortage of place

DefinitionAn impacted tooth is a tooth that fails to fully pass through the gums.Impacted tooth is any tooth that is prevented from reaching its normal position in the mouth by tissue, bone, or another tooth (archer, 1975)ED : Erruptio difficilis

Causes

Sistemic Prenatal : herediter, hormonal, genetic defect (cleft palate, ectodermal displasia,..)Post natal : acquired (TB, malnutrition,..)

LocalAbnormality position Density of arround bonesChronic inflamation of gum that covered itEarly extraction of deciduous teeth

Others theory : Antropologic

The cause may be overcrowding, often because the jaw is too small to fit the third set of molars.

Teeth may also become twisted, tilted, or displaced as they try to emerge, resulting in impacted teeth.

Impacted wisdom teeth are very common. They are often painless and cause no apparent trouble. Impacted tooth pushes on the next tooth, eventually causing a misalignment of the bite.

A partially emerged tooth can trap food, plaque & debris in the soft tissue around it, leading to inflammation that is called pericoronitis/operculitis.

Pericoronitis Symtoms Pain or tenderness of the gums (gingiva) or jaw bone Unpleasant taste when biting down on or near the area Bad breath

Redness and swelling of the gums around the impacted tooth Swollen lymph nodes of the neck/ sub mandible (occasionally) Difficulty opening the mouth (occasionally)

Complications

Recurrent infection of a partially buried tooth Abscess of the tooth/gums Malocclusion of the teeth Chronic discomfort in the mouth "Plaque traps"

Prolonged headache or jaw acheVertigo, TinitusMalocclution Transform to odontogen cyst

ExaminationX-ray panoramic taken when : Cannot open the mouthTo confirm the presence 1 or more teeth that have not emerged

TreatmentGoal : to relieve irritation caused by impact tooth No infection no treatmentCause infection tooth removal, odontectomyAntibiotic & analgetics
