Relationship between the Apical Preparation Diameter and the Apical Seal: An In Vitro Study
Objectives The aim of the study is to define the relationship between the apical preparation diameter and the apical sealing ability to highlight the importance of the preservation of the diameter and the original position of the apical foramen. Materials and Methods 50 extracted maxillary incisors were randomly allocated into three groups of 15 teeth each (n = 15) according to the apical pre...
متن کاملApical seal versus coronal seal
the results of the initial study. It was concluded that the apical fluids, with their primary source being blood serum, diffuse into the empty canal spaces, stagnate, undergo degradation and then act as a physicochemical irritant when they diffuse back into periapical tissues. In support of this theory of stagnation, in 1955 Dow and Ingle showed that the majority of the endodontic failures were...
متن کاملAn in vitro comparison between the apical seal of thermafil with lateral and vertical condensation techniques in mesiobuccal root of maxillary molars
the purpose of this study was to compare the apical seal mof thermafil with lateral and vertical condensation techniques in mesiobuccal root of maxillary first molars. 245 upper first molarteeth were extracted.among them 40 teeth were selected having 20-25 degrres of curve(according to schnider analysis) in apical one their of their mesiobuccal roots.these teeth were also selected so that the...
متن کاملEffect of Post-Space Preparation on Apical Seal of Endodontically Treated Teeth
ABSTRACT By restoration of pulpally exposed teeth with root canal therapy edentulous areas and neighbouring teeth displacement can be avoided. Prefabricated posts may be used for crown restoration of these teeth. For the preparation of root canal for post placement, Gutta percha should be removed by means of mechanical, thermal and chemical agents. To study the amount of apical leakage in vit...
متن کاملComparative evaluation of apical debris extrusion between RaCe and Komet F6 An Ex-Vivo Study
Background & Aim: Apical extrusion of debris is one of the reasons for flare-up(pain,swelling,or both). This study aimed to determine the apical debris extrusion of two rotary systems(RaCe and Komet F6 SkyTaper) in curved mesiobuccal canals of mandibular first molars. Material and methods: Thirty mandibular first molars (with mesiobuccal canal curvature 25-35 degree) were included in this ex...
