Apical 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 کاملPierre Machtou presents a review of the clinically relevant literature on apical seal versus coronal seal Apical seal versus coronal seal CPD
19 The biological basis of endodontics is well established and underlines the dominant role of bacteria in the initiation, development and persistence of periapical disease (Kakehashi S et al, 1965) or apical periodontitis (AP) according to the terminology currently in use. The aim of clinical procedures is to prevent or eliminate bacterial infection from the root canal system (Orstavik D, Pitt...
متن کاملIn Vivo Microleakage Evaluation of Two Root Filling Materials in Teeth without a Coronal Seal
Derek Duggan In vivo microleakage evaluation of two root-filling materials in teeth without a coronal seal (Under the direction of Dr. Martin Trope) Two carrier-based materials were compared to assess their resistance to coronal microleakage in a dog model when no coronal seal was present. Histologic evidence of inflammation and infection were the outcome parameters used. Experimental teeth wer...
متن کاملCoronal microleakage of five materials used to create an intracoronal seal in endodontically treated teeth.
The purpose of this study was to quantitatively compare the sealing effectiveness of five restorative materials that were used to create an intracoronal double seal. Fifty-two extracted mandibular molars were randomly divided into five groups of 10 teeth, and one positive and one negative control tooth. The crowns were removed and the pulpal floor and canal orifices were sealed with 3 mm of one...
متن کاملDoes cold burnishing gutta-percha create a better apical seal?
This study investigated the seal created by cold burnishing the gutta-percha exposed after apical root resection of endodontically treated teeth. Sixty single-rooted extracted human teeth with a single straight canal were divided into four experimental groups of 15 teeth each. In two of the experimental groups the canals were instrumented and obturated well with laterally condensed gutta-percha...
