Abstract

In this study, #40 size gutta-percha points of 9 brands were evaluated by profile projector with respect to size accuracy of ISO standards at Dx and D2 points. Additionally, surface morphology of the apical ^hirds of these gutta-percha cones was analyzed by scanning electron microscopy. Kerr and Dentsply cones at Dx point, and Zipperer, Dentsply and Maillefer cones at D2 point were not accurate according to ISO standards. However, scanning electron microscopic observations showed that surface morphology of only Dentsply cones was smooth and uniform without defects.

Özet

Bu çalışmada, ülkemizde halen kullanıl¬makta olan güta-perka konlarm standartlara uygunluğu ve yüzey morfolojileri araştırıldı. Her firmaya ait 10 adet 40 no'lu güta-perka konun çapı, ISO tarafından saptanan D] ve D2 nokta¬larında profil projektörü yardımı ile ölçüldü. Ayrıca, bu konlarm apikal bölüm- lerinin yüzey morfolojileri taramalı elektron mikroskopta çe¬şitli büyütmelerde incelendi. Test edilen güta-perka konlardan Kerr ve Dentsply firmasına ait konlarm Dj noktası stan¬dartlarına; Zipperer, Dentsply ve Maille/er 'in ise D2 noktası standartlarına uygun olmadığı saptandı. Ancak, elektron mikroskop ile yapılan gözlemlerde ise, yalnızca Dentsply'a. ait örnek¬lerin yüzeylerinin düzgün olduğu ve defekt içer¬mediği belirlendi.
