Gelio sud\u0117tyje yra seili\u0173 chemini\u0173 med\u017eiag\u0173, kurios atstato ir regeneruoja dant\u0173 emal\u012f \u2013 tod\u0117l gali pad\u0117ti i\u0161vengti dant\u0173 \u0117duonies, d\u0117l kurio galiausiai reikia plomb\u0173.<\/p>\n

Emalis \u2013 kietas, blizgus dant\u0173 pavir\u0161iaus sluoksnis \u2013 apsaugo jautrius vidinius sluoksnius nuo nusid\u0117v\u0117jimo, r\u016bg\u0161\u010di\u0173 ir bakterij\u0173. \u201eEmalis yra pirmoji gynybos linija. Kai \u0161i gynybos linija pradeda silpn\u0117ti, dant\u0173 \u0117duonis pagreit\u0117ja\u201c, \u2013 sako Alvaro Mata i\u0161 Notingemo universiteto Jungtin\u0117je Karalyst\u0117je. Emalis nat\u016braliai nesiregeneruoja, o tokie gydymo b\u016bdai kaip fluorido lakai ir remineralizacijos tirpalai tik neleid\u017eia situacijai pablog\u0117ti.<\/p>\n

Ie\u0161kodami sprendimo, A. Mata ir jo kolegos suk\u016br\u0117 gel\u012f, kurio sud\u0117tyje yra modifikuota baltymo versija \u2013 kuri\u0105 jie modifikavo taip, kad ji veikt\u0173 kaip amelogeninas: baltymas, padedantis reguliuoti emalio augim\u0105 k\u016bdikyst\u0117je.<\/p>\n

Eksperimentai, kuri\u0173 metu naudojantis mikroskopu gelis buvo tepamas ant \u017emogaus dant\u0173, naudojant kalcio ir fosfato tirpalus (pagrindines emalio sudedam\u0105sias dalis), parod\u0117, kad jis sukuria plon\u0105 ir tvirt\u0105 sluoksn\u012f, kuris i\u0161lieka ant dant\u0173 kelet\u0105 savai\u010di\u0173, net ir valant dantis.<\/p>\n

Gelis u\u017epildo skyles ir \u012ftr\u016bkimus, sukurdamas karkas\u0105, kuris naudoja kalcio ir fosfato junginius, kad skatint\u0173 nauj\u0173 kristal\u0173 augim\u0105 emalyje po gelio sluoksniu \u2013 net jei jo buvo prarasta tiek daug, kad po juo atsideng\u0117 danties dentinas.<\/p>\n

\u201eGelis sugeb\u0117jo epitaksiniu b\u016bdu auginti kristalus \u2013 o tai rei\u0161kia, kad jos kristalin\u0117 orientacija yra tokia pati kaip esamo emalio\u201c, \u2013 sako A. Mata.<\/p>\n

\u0160i orientacija rei\u0161kia, kad naujas augimas, kuris pasiek\u0117 iki 10 mikrometr\u0173 stor\u012f, yra integruotas \u012f po juo esant\u012f nat\u016bral\u0173 audin\u012f, atkurdamas emalio strukt\u016br\u0105 ir savybes. \u201eAugimas i\u0161 ties\u0173 \u012fvyksta per savait\u0119\u201c, \u2013 sako A. Mata. \u0160is procesas taip pat veik\u0117 naudojant donor\u0173 seiles, kurios taip pat nat\u016braliai turi kalcio ir fosfato, o ne tik komandos naudot\u0105 tirpal\u0105, sudaryt\u0105 i\u0161 \u0161i\u0173 chemini\u0173 med\u017eiag\u0173.<\/p>\n

Apie pana\u0161\u0173 metod\u0105 buvo prane\u0161ta 2019 m.<\/a>, ta\u010diau jis leido pagaminti plonesnius dangalus, o emalio vidini\u0173 sluoksni\u0173 strukt\u016bra buvo atkurta tik i\u0161 dalies.<\/p>\n

Klinikiniai tyrimai su \u017emon\u0117mis numatyti kit\u0173 met\u0173 prad\u017eioje. A. Mata taip pat \u012fk\u016br\u0117 \u012fmon\u0119 \u201eMintech-Bio\u201c ir tikisi, kad pirmasis produktas, kur\u012f, jo manymu, naudos stomatologai, pasirodys 2026 m. pabaigoje.<\/p>\n

Tyrimas paskelbtas \u017eurnale \u201eNature Communications\u201c<\/a>.<\/p>\n
