Kunyangwe dambudziko remazino e "yellow" richinyanya kunaka, rinogona kunetsa kune munhu ari kubatwa uye kuomesesa. Nekudaro, yakaoma inogona kutadzisa kuzvivimba, hukama nevamwe, kugona kwekunyengera kwemunhu uye kushamwaridzana kwake. Saka, mazino eyero: ndivanaani vane mhosva?

Korona yezino inoumbwa nezvikamu zvitatu izvo enamel uye dentin chikamu. Iyo enamel ndiyo inooneka chikamu chezino. Zviri pachena uye zvizere mineralized. Ndiro chikamu chakaomesesa chemuviri wemunhu. Inodzivirira mazino kubva pakurwiswa kweasidhi uye zvinokonzerwa nekutsenga. Dentin ndiyo iri pasi peiyo enamel. Yakanyanya kana kushoma. Ichi chikamu chinonzi vascularized (= midziyo yeropa inopa muviri).

Mumvuri wezino unotarirwa neruvara rwedentin uye ukobvu hweenamel.

Kurangarira:

Iyo enamel inopera nekufamba kwenguva uye kuunganidzwa kwemarara emarudzi ese. Kupfeka uku kunoita kuti zvive zvishoma uye zvishoma uye zvishoma uye zvakanyanya uye zvakajeka. Kunyanya kujeka kuri, kunowedzera kuoneka kwayo pasi, iyo dentin, iri.

Zvingave zviri zvemukati kana zvekunze zvinhu, PasseportSanté yaita ongororo yayo kuti ikuzivise kuti ndiani ane mhosva yekutsvuka kwemeno.

Kana zvasvika pamazino machena, hatisi tese takazvarwa takaenzana. Ruvara rwemazino edu runoenderana nekusiyana neruvara rweganda redu kana matinji edu. Rudzi rwemazino edu runogona kutsanangurwa neiyo genetic factor, kunyanya nhaka.

Iyi haisi nhau: fodya inokuvadza kune hutano huzhinji, uyewo kumuromo wemuromo. Zvimwe zvikamu zvefodya (tar uye nicotine) zvinokonzeresa makwapa ero kana matema, anogona kuonekwa seasingataridzike. Iyo nicotine inorwisa enamel, nepo tara inokonzera kusvibisa ruvara rwedentin. Pakupedzisira, kubhurasha kuri nyore hakuzokwani kuti ubvise aya mavara. Mukuwedzera, fodya inobatsira mukugadzirwa kwetartar iyo inogona kukonzera kuumbwa kwemakumbo.

Dentin ndiyo vascularized chikamu chezino. Kuburikidza neropa, kutora mishonga, kusanganisira mamwe maantibioti, inokanganisa ruvara rwayo. Tetracycline, mushonga unorwisa mabhakitiriya wakanyanya kunyorerwa mukati me70s uye 80s kuvakadzi vane nhumbu, yakave nemhedzisiro paruvara rwemeno emwana muvana. Mushonga unorwisa mabhakitiriya uyu wakanyorerwa vana une simba guru paruvara rwemazino avo anogara aripo. Ruvara runogona kusiyana kubva kune yero kusvika kune brown kana kunyange grey.

Fluoride inosimbisa enamel yezino. Inobatsira kuve nemazino akasimba uye zvakanyanya kushingirira kumakomba. Kunyanya kushandisa fluoride kunokonzera fluorosis. Uku ndiko kuumbwa kwemavara pamazino ayo anogona kugomara uye kuita ruvara. MuCanada, hurumende yakadzika mitemo ine chekuita nezvemhando yemvura yekunwa.

Kuva nehutsanana hwemukanwa hwakakosha. Inodzivirira acid uye bhakitiriya kurwisa mumuromo. Saka zvakakosha kukwesha mazino ako kanenge kaviri pazuva kwemaminetsi maviri. Floss inoshanda uko bhurasho rezino risingakwanisi. Kukwesha mazino ako kunobvisa tartar uye kunobatsira kuchengetedza kuchena kwemazino ako.

Kurwisa kutsvuka kwemazino avo, vamwe vanhu vanoshandisa mazino kuchenesa nekushandisa hydrogen peroxide (= hydrogen peroxide). Tsika iyi haifaniri kurerutswa. Kushandisa zvisina kunaka hydrogen peroxide kunopedza simba uye kunoita kuti mazino ave nesimba. Kuongororwa nemuromo saka kunopfuura kudikanwa. Zvingave zvichibva mukunaka kana kurapwa, kuchena kwezino kunofanirwa kutevedzera mitemo yakasimba.
