Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Anodontia kushayikwa kwakakwana kwokukura kwemeno, uye hypodontia kushayikwa kwokukura kwemeno. Anodontia ishoma, inowanzoitika muchimiro chinonzi hypohidrotic ectodermal dysplasia, nepo hypodontia iri imwe yezvakajairika kukura kusagadzikana, ichikanganisa 3.5-8.0% yevagari (kusasanganisira yechitatu molars). Kushaikwa kwemamolar wechitatu kwakajairika, kunoitika mu20~23% yevagari, kuchiteverwa nekupararira kwechipiri premolar uye lateral incisor. Hypodontia inowanzosanganiswa nokushayikwa kwedehenya remeno, iro rinokanganiswa nemasimba emhoteredzo, akadai sechirwere uye mishonga yemakemikari, uye rinosanganiswawo nezvirwere zvakawanda, zvakadai seDown syndrome uye Crouzon syndrome. Hyperdontia ndiko kukura kwemeno ekunze. Inoitika mu1<unk>3% yevaCaucasians uye inowanzoitika muAsia. Inenge 86% yezviitiko izvi inobatanidza zino rimwe chete rinowedzerwa mumuromo, rinowanzonyanya kuwanikwa mu maxilla, umo mune mazino anopinza. Hyperdontia inofungidzirwa kuva yakabatanidzwa neyakawandisa yemazino lamina.  Mubvunzo: Chii chinonzi Hypodontia?
