LİTERATÜRDE IN VITRO ELEKTRONİK APEKS BULUCU ÇALIŞMALARINDA KULLANILAN ORTAM ÇEŞİTLERİ: BİR DERLEME

Kök kanalı tedavisinde uzun vadeli başarı, kök kanal sisteminin en uygun şekilde dezenfeksiyonu, preparasyonu ve doldurulması ile mümkündür. Kanal tedavisinin sonlanacağı yeri belirlemek tedavinin en önemli basamaklarından biridir. Preparasyonun taşkın yapılması post-operatif ağrıyı artırabilirken, kısa kök kanal dolgusu yeterli dezenfeksiyonun yapılamamasına sebep olabilir. Bu aşamada, elektronik apeks bulucular (EAB) yüksek bir doğruluk seviyesinde apikal daralımın yerinin tespit edilmesine yardımcı olmaktadırlar. Çalışma prensibi genel olarak dokular arasındaki empedans farkının tespitine dayanmaktadır. Elektronik apeks bulucu cihazların, hastada kullanılmadan önce doğruluğunun araştırılması başarılı tedaviler açısından önemlidir. Aynı zamanda, apeks bulucuların ölçme başarısını etkileyebilecek kanal içi solüsyonların, ilaçların, enstrümanların in vitro çalışmalarla değerlendirilmesi önemlidir. Piyasada bulunan apeks bulucuların ölçüm doğruluklarını değerlendiren birçok in vitro çalışma yapılmıştır. Bu in vitro çalışmalar gerçekleştirilirken periapikal dokuları taklit edecek elektro-iletken test ortamları gereklidir. Kullanılan test ortamları jelatin, aljinat, agar agar, salin solüsyonu, çiçek süngeridir. Bu derlemenin amacı, literatürdeki in vitro çalışmalarda kullanılan test ortamları hakkında bilgi vermektir. Anahtar kelimeler: endodonti, kök kanal tedavisi, diş apeksi. MEDIA VARIETIES USED IN IN VITRO ELECTRONIC APEX LOCATORS STUDIES IN LITERATURE: A REVİEW SUMMARY Long-term success in root canal treatment is possible with appropriate disinfection, preparation and filling of the root canal system. Determining the ending point of root canal therapy is one of the most important steps of the treatment. While over-preparation can increase the post-operative pain, short root canal filling may cause inadequate disinfection. At this point, electronic apex locators (EAL) help to locate the apical constriction with high accuracy level. The principle of operation is generally based on the detecting the impedance difference between tissues. It is important to investigate the accuracy of electronic apex locators before using them in patients with regard to successful treatments. To evaluate the intra-canal solutions, medicaments, instruments, which may affect the measuring success of apex locators, is important by means of in vitro studies. Many in vitro studies have been done to evaluate the accuracy of apex locators on the market. Electroconductive test environments that mimic periapical tissues are required when performing these in vitro studies. The test media used are gelatin, alginate, agar agar, saline solution, flower sponge. The purpose of this review is to provide information about in vitro test environments used in the literature. Keywords: endodontics, root canal therapy, tooth apex.

Anahtar Kelimeler:
