G�R�� ve AMA�: Bu �al��man�n amac� yapay olarak olu�turulan horizontal k�k k�r�klar�n�n te�hisinde iki farkl� elektronik apeks bulucu cihaz�n (Dentaport ZX and Rootor) etkinli�inin kar��la�t�r�lmas�d�r.
Y�NTEM ve GERE�LER: 40 adet tek k�kl� �ekilmi� daimi di� her bir grupta 20 adet olmak �zere 2 guruba ayr�ld�. 0.25 mm kal�nl��nda elmas separe kullan�larak k�klerin orta ve apikal ��l� hizas�nda horizontal k�r�k hatlar� olu�turuldu. Aljinat model i�ine yerle�tirilen k�kler �zerinde her iki apeks bulucu ile horizontal k�r�k hatlar�n�n tespiti 10 K e�esi kullan�larak yap�ld�. Ger�ek �l��mler ayn� e�e kullan�larak stereomikroskop (SMZ 800, Nikon, Tokyo, Japan) kullan�larak tespit edildi. Ger�ek ve elektronik �l��mler aras�ndaki fark hesapland�. �statistiksel incelemelerde Mann-Whitney U ve Wilcoxon E�le�tirilmi� �ki �rnek Testi testleri kullan�ld�.
BULGULAR: Dentaport ZX ve Rootor apeks bulucular�n orta ve apikal horizontal k�r�k seviyelerinde elektronik ve ger�ek �l��mlerin farklar�n�n ortalamalar� s�ras� ile -0.12 � 0.27; 0.09 � 0.38; -0.10 � 0.25; 0.18 � 0.53 mm�dir. Dentaport ZX orta horizontal k�r�k seviyesinde 18 �rnekte ve apikal horizontal k�r�k seviyesinde 19 �rnekte, Rootor ise orta horizontal k�r�k seviyesinde 12 �rnekte ve apikal horizontal k�r�k seviyesinde 11 �rnekte ger�ek �l��mlere k�yasla �0,5 mm i�erisinde tespitler yapm��t�r. Her iki k�r�k seviyesinde Dentaport ZX ile Rootor�a ait �l��m de�erleri aras�ndaki farkl�l�k istatistiksel olarak �nemli bulunmu�tur (p<05). Ancak Dentaport ZX ile Rootor gruplar�n�n kendi i�erisinde orta ve apikal k�r�k seviyeleri �l��m de�erleri aras�nda istatistiksel farkl�l�k tespit edilmemi�tir (p>.05).
TARTI�MA ve SONU�: Dentaport ZX ile yap�lan �l��mler ger�ek �l��mlerden daha k�sa tespit edilirken, Rootor �l��mleri daha uzun tespit edilmi�tir. Ayr�ca �0.5 mm i�erisinde elde edilen �l��m say�s� Dentaport ZX�de Rootora g�re daha fazlad�r. Bu ko�ullar alt�nda; Dentaport ZX ile yap�lan �l��mlerin daha kabul edilebilir oldu�unu s�yleyebiliriz.

INTRODUCTION: The aim of this study was to evaluate in vitro the effectiveness of the two different electronic apex locators (Dentaport ZX and Rootor-EALs) in locating simulated horizontal root fractures.
METHODS: Forty extracted human single-rooted teeth with mature apices were randomly divided into two groups of 20 teeth each. An incomplete horizontal fracture was simulated by preparing a with a 0.25 mm thick disk in the middle and apical portion of the root and the teeth were mounted in an alginate mold. The electronic measurements (ELs) of the simulated root fractures were established with a size 10 K-file by each EAL in both fracture levels. The actual canal lenghts (ALs) were measured under a stereomicroscope. The ALs were subtracted from the ELs of the fractures. The data were analyzed using the Mann-Whitney U and the Wilcoxon signed-rank tests at a significance level of P <.05.
RESULTS: The mean differences between the ELs and ALs were -0.12 � 0.27; 0.09 � 0.38; -0.10 � 0.25; 0.18 � 0.53 mm in the Dentaport ZX and Rootor groups and middle and apical horizontal fracture levels, respectively. The Dentaport ZX performed measurements within �0.5 mm in 18 and in 19 samples while the Rootor performed in 12 and in 11 samples, middle and apical horizontal fracture levels respectively. Statistically, significant differences were found among the EALs at both horizontal fracture levels (P <.05). However; no statistically significant differences were found between the fracture levels in each of the EALs (P >.05).
DISCUSSION AND CONCLUSION: The Dentaport ZX measurements were shorter than ALs whereas the Rootor measurements were longer than Als. Furthermore, the number of measurements obtained within � 0.5 mm in Dentaport ZX is more than that of Rootor. Under the conditions of this study, the Dentaport ZX group showed an acceptable determination of the horizontal root fracture.
