Cand se scoate nervul unui dinte?

extractie nerv, obturare canal, obturatia de canal
Dentist.ro | 15.11.2010



Obturatia de canal este tratamentul folosit pentru a repara sau a salva un dinte care este grav cariat sau infectat. In timpul procedurii obturatiei de canal, nervul si pulpa dintelui sunt indepartate, iar interiorul dintelui este curatat si sigilat. Fara aplicarea vreunui tratament, tesutul din jurul dintelui se va infecta si se pot forma un abces dentar.

Nervul unui dinte nu are o importanta vitala in sanatatea si functionalitatea unui dinte, dupa ce acesta a crescut din gingii. Are doar o functie senzoriala - este responsabil de a detecta senzatiile de rece sau de cald, in contactul cu dintii. Prezenta sau absenta unui nerv nu va afecta functionalitatea zilnica a unui dinte.


De ce trebuie indepartata pulpa dentara?



Atunci cand tesutul nervos al unui dinte este afectat, bacteriile se inmultesc in sacul pulpei. Acestea sunt responsabile de infectiile dentare sau de abcesele dentare. Un abces dentar are loc atunci cand infectia se imprastie in sacul pulpei ajungand pana la radacina dintelui.

Pe langa abcesul dentar, infectia pulpei dentare se poate manifesta prin:

- umflarea fetei, a gatului, a capului
- pierderea unui os din zona dintelui afectat
- probleme de drenaj din zona dintelui afectat


Ce cauzeaza pierderea nervului si a pulpei dentare?



Pulpa si nervul unui dinte pot deveni iritante, inflamate si infectate din cauza infectiilor adanci, proceduri dentare repetate pe un dinte, plombe prea mari, crapaturi sau sparturi ale dintilor sau o trauma a fetei.


Prevenirea obturatiei de canal



Motivul pentru care medicul dentist opteaza la o obturatie de canal este carierea dintelui destul de grav, inflamarea si infectarea tesutului din jurul acestuia. Procedurile dentare repetate pe un dinte, urmate de practicile de o igiena orala corecta (spalarea pe dinti de cel putin doua ori pe zi, folosirea atei dentare cel putin o data pe zi, programarea regulata a vizitei la medicul dentist) pot reduce riscul aparitiei cariilor si implicit evitarea obturatiei de canal.


Care sunt semnele pentru care as avea nevoie de o obturatie de canal?



Uneori semnele nu sunt prezente, insa iata cateva dintre ele:

- dureri severe de dinti, in special in procesul de masticatie sau la existenta unei presiuni
-sensibilitate prelungita sau durere la expunerea la temperaturi ridicate sau scazute
- decolorarea dintelui
-umflarea gingiei din zona dintelui

ite soccer they own shit If you
-faced Ice Cube not looking exactly thrilled to be there. [Laughs] Was Cube a little salty that The D.O.C. was getting his solo shot before he could?The D.O.C.: Nah. Hell nah. We was all together then. Now, this is some foul shit, but in the early N.W.A., way before I got my chance, whenever these guys did interviews, whenever they took pictures, whenever they did videos, they went out of they way not to let me in ‘em. If you go back you’ll never see me in none of ‘em. They wouldn’t let me in ‘em. They didn’t.Aliexpressite t want me there, I think because they didn’t want muthafuckas to know that they wasn’t writing they own shit. If you go back to they old interviews, [when] the interviewers would ask them muthafuckas questions they would look fuckin’ dumbfounded. Because, the questions that they were asking the muthafuckas was about lyrics that I wrote for ‘em. Only Cube really understood I think what the aim was. Dre did sonically. But Cube understood what we was .ite soccer trying to aim for. That’s why his subsequent albums were in that same vein. DX: Let me take it back to “It’s Funky Enough” …. Is this story true that you were just fuckin’ around when you spit that now classic Jamaican patois delivery, and that was just one take?The D.O.C.: That was one take. They used to call me “One Take Willie.” We started that. Kurupt is the only other muthafucka to do that. … I had begged Dre to make that beat [using Foster Sylve.ite soccer store s “Misdemeanor”]. It took me about three fuckin’ months of begging him to make that beat before he finally made it. And those lyrics were actually meant for another song, but I didn’t have no words for that beat yet. So when I went in, I was just gonna lay something so he could finish adding the instrumental shit into the track. And when the beat came on, it just sounded Jamaican. So that’s the character that came out. And I just spit that shit. Muthafuckas kept motioning me to keep going, so I did. At the end of that I was like, “Well I can do it better.” Dre was like, “Fuck that! I’m not changing none of that shit.” D
