Endodontik davolashning muvaffaqiyati ko‘p jihatdan ildiz kanallari tizimining to‘liq sanatsiyasi va germetik obturatsiyasiga bog‘liq, biroq Enterococcus faecalis ning saqlanib qolishi surunkali apikal periodontit va kasallikning qaytalanishiga tez-tez olib keladi. Epoksid asosli silerlar yaxshi fizik-kimyoviy xususiyatlarga ega, ammo ularning antimikrob faolligi cheklangan; tarkibiga to‘rtlamchi ammoniy birikmalarini qo‘shish materialning antibakterial salohiyatini kuchaytiradi, bu esa ushbu tadqiqotning dolzarbligini belgilaydi. Tadqiqot maqsadi: surunkali apikal periodontitni davolashda an’anaviy epoksid silerlar va to‘rtlamchi ammoniy qo‘shimchasini o‘z ichiga olgan silerlarning klinik va rentgenologik samaradorligini taqqoslash. Materiallar va usullar: tadqiqotga 20 nafar bemor jalb qilindi, ular 2 guruhga bo‘lindi (nazorat guruhi, n=10 — an’anaviy siler; asosiy guruh, n=10 — modifikatsiyalangan siler). Barcha bemorlarga standart endodontik davolash lateral kondensatsiya usuli bilan obturatsiya qilingan holda o‘tkazildi; klinik baholash 1, 3, 6 va 12 oyda, rentgenologik baholash 12 oyda amalga oshirildi; statistik tahlil χ²-testi yordamida bajarildi (p<0,05). Natijalar: asosiy guruhda simptomlar kamroq kuzatildi va tezroq yo‘qoldi; 12 oyda to‘liq sog‘ayish asosiy guruh bemorlarining 80% da, nazorat guruhida esa 50% da qayd etildi (χ²=4.00; p=0,045). Xulosalar: to‘rtlamchi ammoniy qo‘shimchali epoksid siler an’anaviy silerga nisbatan klinik va rentgenologik ko‘rsatkichlarni yaxshilaydi, bu uning kuchli antimikrob faolligi bilan bog‘liq; biroq, natijalarni tasdiqlash uchun ko‘proq bemorlar ishtirokida va uzoq muddatli kuzatuvli tadqiqotlar zarur.
