EVALUATION OF THE EFFECT OF DIFFERENT COMBINATIONS OF IRRIGATING SOLUTIONS AND CORE MATERIALS ON THE FRACTURE RESISTANCE OF ENDODONTICALLY TREATED TEETH.

Abstract
Aim: The aim of this study is to evaluate the effect of using different
irrigating solutions (EDTA and Sodium hypochlorite (NaOCL)) during
root canal treatment combined with different composite core materials
(Multicore Flow (MCF) and SonicFill (SF) on the fracture resistance of
endodontically treated teeth.
Material and Methods: 40 recently extracted mandibular first
premolar teeth were selected. Teeth were randomly divided into two
groups (n=20) according to the irrigating solution used during root
canal treatment; Group I: EDTA, Group II: Sodium hypochlorite
(NaOCL). Each main group was further subdivided into two equal
subgroups (10 each) according to core material used; Subgroup A:
Multicore Flow (Ivoclar Vivadent, Schaan, Liechtenstein) (MCF),
subgroup B: SonicFill (SF) (Kerr, Orange, CA, USA). The force in
newton (N) was applied obliquely to the buccal cusp tips utilizing a
specially designed attachment at cross head speed of 0.5mm/ minute
until fracture and the maximum loads at which failure occurred were
recorded.
Results: no significant difference among the tested core material was
recorded, however a significant difference with irrigating solutions was
recorded where sodium hypochlorite significantly decreased fracture
resistance more than EDTA with both core materials.
