Seeding hauv paus canals yog ib qho txheej txheem kev tswj thiab yuav tsum tau ua qee cov theem. Feem ntau, cov kwj deg tau ua thaum kho cov hniav uas cuam tshuam los ntawm cov kab mob, qhov mob ntawm cov kua txob thiab qhov chaw mob .
Kev npaj rau txhaws
Cov txheej txheem no muaj ob peb theem tseem ceeb, kev ua tiav ntawm kev siv tshuab uas yuav yog qhov kev lees paub ntawm tus txheej txheem tsim nyog:
- Tshem tawm cov ntaub so ntswg uas puas lawm.
- Tshem tawm ntawm pulp (cov ntaub so ntswg, nrog rau kev tso ntshav ntawm cov ntshav thiab lymph cov hlab ntsha).
- Nqa tawm kev ntsuam xyuas siv X-ray hluav taws xob los txiav txim siab txog cov ceg ntoo thiab qhov tob hauv cov hauv paus hniav.
- Tu, ua kom zoo nkauj rau phab ntsa thiab nthuav cov ntu nrog cov cuab yeej tshwj xeeb.
Hom filling
Seeding ntawm hauv paus kwj dej yuav ua tau ib ntus. Hom kev sib khi no siv rau hauv cov txheej txheem mob hauv cov ntaub so ntswg uas yuav tsum tau kho nrog kev siv tshwj xeeb pastes. Pastes muaj peev xwm:
- tshuaj tua kab mob;
- corticosteroids ;
- metronidazole los yog calcium hydroxide.
Lawv tau tso rau hauv cov kab noj uas muaj mob thiab qhov puv ntoob ntawm cov hauv paus canals yog ua tiav.
Hauv rooj plaub yog tias tsis muaj kev kho mob ntxiv, yuav tsum tau ua kom tiav rau ntawm cov hauv paus hniav. Nyob rau hauv cov ntaub ntawv no, npaj cov yas kho nrog Cresophene los yog Parkan (cov tshuaj tua kab mob).
Txoj kev txhim kho
Muaj ob peb txoj kev rau sealing hauv kwj dej:
- nrog kev siv cov kws kho hniav tshwj xeeb qoob loo;
- siv tus pin uas tau ua los ntawm gutta-percha, titanium, tsawg zaus nyiaj;
- ua ke nrog, simultaneous daim ntawv thov ntawm tus pin thiab paste (Thermophil system);
- nrog kev pab ntawm txias thiab rhuab gutta-percha.
Cov ntaub ntawv rau kev sib khi
Cov ntaub ntawv rau sealing lub hauv paus kwj deg yuav tsum tau ua raws li ntau cov cai:
- yuav tsum muaj zog tshwj xeeb tshaj thiab tsis txuam nrog qaug tshuaj ntawm cov organic thiab cov kua nqaij kua;
- ua kom tsis muaj zog;
- muaj radiopaque;
- Tsis txhob ntxias kev mob thiab kev fab tshuaj.
Hauv kev kho hniav niaj hnub tam sim no rau hauv paus kwj deg sau:
- polymeric silvers;
- iav ionomer cement (ntau zaus siv hauv qhov kev kho menyuam yaus);
- polydimethylsiloxanes;
- xis mas nrog calcium hydroxide.
Txoj kev mummification thiab txhaws nrog resorcinol-formalin sib tov tau kuj muaj ntau. Tam sim no, cov hau kev no dhau mus dhau los lawm thiab tsis siv.
