Akanwa ni kimwe mu bice bigize umubiri wacu by’umwihariko ni kimwe mu bice bigize umutwe. Tugakoresha mu bintu bitandukanye yaba mu kurya, kunywa, kuvuga, guseka, kuririmba,n’ibindi.
Muri ibyo bice bigize akanwa tugiye kwibanda cyane ku gice kitwa iryinyo kuko nicyo gice abantu benci bahora bataka ko kibarembeje. Nkuko tubikesha urubuga toothclub ,mu buzima bwacu bwose, tumera amenyo ibika bibiri: amenyo yo mu bwana n’amenyo yo mu bukuru. Tugira amenyo 20 yo mu bwana ndetse na 32 yo mu bukuru. Hari igice cy’iryinyo cyitwa Dentine kikaba kiri imbere y’ikindi gice gikomeye cy’iryinyo cyitwa Enamel. Iyi Dentine ikaba ifite ibara ry’umuhondo naho enamel ikaba ibonerana mu menyo y’ubukuru kurusha mu menyo y’abana. Iyo urebye ku menyo yo mu bukuru usanga iyo Dentine ariyo igaragara kuko usanga ari umuhondo cyane kurusha amenyo yo mu bwana. Uko ugenda ukura mu myaka, amenyo yawe agenda asa n’umuhondo kubera ko ya Dentine igenda ikomera.

Amenyo  yo mu bwana(ibumoso) ndetse n'ayo mu bukuru (iburyo)

Ibice bigize iryinyo:
Iryinyo rigizwe n’ibice bitandukanye ariko bikaba bigabanyijemo bibiri. Hari ibice bikomeye ndetse n’ibice byoroshye (hard and soft tissues). Urebeye inyuma usanga iryinyo rigizwe n’ibice bibiri aribyo imizi n’umutwe (root and crown).
Ibice bikomeye (hard tissues):
  • Cementum: Ni igice gikomeye cy’inyuma ku muzi w’iryinyo. Gihuza ibice bizengurutse iryinyo (periodontal membrane) na dentine y’umuzi w’iryinyo. 
  • Dentine: Nicyo gice cya kabiri cya crown uvuye inyuma, gisa n’umuhondo, kikaba gifite utwenge imbere dutuma iyi dentine ihura n’umutima w’iryinyo (Pulp). 
  • Enamel: Ni igice cy’inyuma ku mutwe w’iryinyo (crown).  Igizwe na calcium, phosphorus, n’ibindi. Nicyo gice gikomeye mu mubiri kandi kibonerana.
Ibice byorohereye (soft tissues):

  • Pulp: Ni umutima w’iryinyo (icyumba cy’imbere mu ryinyo), kibamo udutsi dutwara amaraso (blood vessels) ndetse n’udutsi dutwara amakuru (nerve fibres). 
 
Hari ibice bizengurutse iryinyo (Periodontal tissues):
  •  Ishinya (gingivae cyangwa gums): Ni igice cyoroshye gitwikiriye igufwa rifata amenyo (alveolar bone), ishobora kuba iroze cyangwa umukara.


  •  Igufwa rifata amenyo (alveolar bone): Rifasha iryinyo gukomera mu mwanya waryo ntirijegajege.  

    Ibice bigize iryinyo; iby'inyuma (ibumoso) n'iby'imbere (iburyo)
Akamaro k’amenyo:

Amenyo ari mu bice bigize akanwa kacu. Adufasha mu guhekenya ibiryo tuba turi kurya. Rimwe na rimwe tujya twisanga amenyo yacu aturya mu gihe turiye cyangwa tunyoye cyane cyane ibishyushye cyangwa ibikonje. Akenshi umuntu uzumva ataka akubwira ko adashobora kunywa ibintu byo muri firigo cyangwa nk’icyayi gishyushye, yewe hari n’umuntu uba udashaka kuvuga ku mugoroba cyangwa mu gitondo hakiri kare kugira ngo akayaga katirukankira mu menyo. Ubwo buribwe buba buri mu menyo buba butandunye n’ubwo umuntu agira mu gihe iryinyo rye ryacukutse. Twifashishije urubuga dental health tugiye kurebera hamwe icyibitera ndetse n’icyo wakora.

Hari ibintu byinci bishobora gutera ishinya guhindura ibara nubwo usanga rimwe na rimwe biba ari ibintu byatewe nuko umubiri wabo usanzwe uteye.
