Kazhinji mazino anomera mukati memuromo mako, asi mumwe murume wekuSaudi Arabia aive nezino raikura munzvimbo isinganzwisisike. LiveScience inoshuma kuti murume uyu aigara achibuda ropa mumhino kubva kamwe kusvika kaviri pamwedzi. Achinetseka, akaenda kuna chiremba uyo akawana chimwe chinhu chinoshamisa zvikuru - zino richikura mumhino dzake.

Mazino ekuwedzera anowanikwa chaizvo. Ongororo yakaitwa inoti vanhu vari pakati pe0,15% ne3,9 percent vane mazino akawanda kupfuura mazuva ese, asi mhuno handiwo painokurira. "Tinoona nyaya dzinoverengeka gore rega rega," Dr. John Hellstein, chiremba wemazino uye purofesa weoral pathology paYunivhesiti yeIowa, aive asina kubatanidzwa munyaya iyi akaudza LiveScience. - izvo hazvina kujairika."

Zino rakaonekwa navanachiremba rakanga rakareba hafu yeinji. Mashoko atiri kutambira anoti kunze kwezino risingawanzo pindikidzwa mumhino dzake, mazino emurume uyu aive ari pakanaka. Murwere aive nechimwe chinhu chinonzi mesiodens, zino rekuwedzera rinowanikwa mumazino e incisor. "Chinenge chikamu chimwe muzvitatu cheavo vanokura vakatsikitsira pasi, uye vanogona kudzoserwa kumusoro, vakananga kumhino," akadaro Hellstein. Vanachiremba vakakwanisa kubvisa zino vachishandisa general anesthesia. Chirevo cheAmerican Journal of Case chinoti murwere uyu ane hutano hwakakwana iye zvino uye akamira kubuda ropa mumhino mwedzi mitatu mushure mekuvhiyiwa.

Mhino haisiriyo yega nzvimbo isinganzwisisike mazino akakura, dzimwe nzvimbo dzinoshamisa dzinosanganisira uropi uye ziso. Apo musoro wemakore mana okuberekwa wakatanga kukura zvisina mwero, vanachiremba vakaongorora uropi hwake vakawana bundu rine mazino mukati maro. Mumwe mukadzi wechiIndia ane makore 22 okukura aiva nebundu raikura muziso rake rine mazino maviri akazara. Mhosva idzi hadziwanzo, asi nhoroondo dzezvekuchera matongo dzakatsvaga humbowo hwemesiodens zviuru zvemakore apfuura. Mesiodens, anonziwo mazino epamusoro-soro, akawanikwa makore 13 000 apfuura pakati pezvisaririra zvemuAborigine wokuAustralia. U.S. National Library of Medicine inoshuma kuti zvisaririra zvekuchera matongo zvemuzana ramakore rechinomwe kuGermany zvakaratidza kuti mamesiodens akapidiguka akaputika mumhino.

Pasinei nekutsvagisa kwese, vanachiremba havasati vanyanya kunyatsoziva kuti nei vanhu vachikura mazino akawedzera. Chimwe chinogona kukonzera kutsemuka kwemuromo uye mukanwa, hurema hwekuzvarwa hunoumbwa kana mukanwa mukasakura zvakanaka. Kuremara kwekuberekwa uku kunoda kuvhiyiwa kunogona kuchinja nzira iyo mazino anokura nayo gare gare muupenyu. Genetics inogonawo kuita basa mukugadzirwa kwemamesiodens. Kutsvakurudza kunoratidza kuti inowanzowanikwa pakati pemitezo yemhuri. Matambudziko eGenetic akadai secleidocranial dysostosis uye Gardner's syndrome ane mhedzisiro inogona kukonzera mesiodens.
