Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Kuumbwa kwesementum kunonzi cementogenesis uye kunoitika pava paya pakuumbwa kwemeno. Cementoblasts ndiwo masero anokonzera simende. Mhando mbiri dze cementum dzinoumbwa: cellular uye acellular. Acellular cementum inotanga kuumbwa. Cementoblasts inosiyana nemasero e follicular, ayo anogona kungosvika pamudzi wemazino kana Epithelial Root Sheat yaHertwig (HERS) yatanga kuora. Cementoblasts inobudisa collagen fibrils yakaisvonaka iri pamudzi usati waenda kure nezino. Sezvo cementoblasts inofamba, collagen yakawanda inochengeterwa kuti irebe uye iwedzere ukobvu hwezvisungo zveshinda. Mapuroteni asiri collagenous, akadai se bone sialoprotein uye osteocalcin, anobviswawo. Acellular cementum ine matrix yakavanzwa yemapuroteni nemafiber. Sezvo kucherwa kunoitika, cementoblasts inobva mu cementum, uye tambo dzasara dziri pamusoro dzinopedzisira dzabatana nemabhonzo anoumba periodontal ligaments.  Mubvunzo: Chii chinokonzera kushandiswa kwecollagen?
