Materiali e metodi\ud
Diciotto soggetti con patologie endodontiche sono stati inclusi nello studio; un totale di 28 canali radicolari è stata preso in considerazione e strumentato con strumenti in lega NiTi (WaveOne - Maillefer - Baillegues - SUI) e sigillati con guttaperca pre-riscaldata (Thermafill-Maillefer - Baillegues - … Show more
“…On the other hand, the cold lateral condensation technique in a non-flared or minimally flared root canal may create voids (Khabbaz et al, 2010). Recently, Silvani et al (2013) investigated the quality of root canal fillings performed by undergraduate students using rotary nickel-titanium files (WaveOne) and preheated gutta-percha (Thermafil) in the clinical setting. The authors of that study found that 26 of the 28 (92.9%) root canal fillings had adequate length, and none of them had voids.…”
The aim of this study was to evaluate the outcomes of teaching endodontics to undergraduate students at Riyadh Colleges. This study was undertaken by assessing the technical quality of root canal obturation and the presence of procedural errors in root canal treatment cases performed by the final year dental students in clinics. All of the root canal treatment cases performed by the final year dental students in the 2nd semester of 2012 to 2013 were examined, with a total of 450 root canals from 241 teeth. The quality of root canal obturation was examined in relation to the length of the root filling based on the radiographic apex, the density of the obturation according to the presence of voids, and the taper of root canal fillings. The overall acceptable quality of the evaluated root canals was 36%. Of these canals, acceptable length, density, and taper were reported in 76.6, 46.4, and 73.8%, respectively. Overall, 9.3% of the treated root canals had procedural errors, and majority of these errors were found in canals of posterior mandibular teeth. Apical transportation was the most encountered error; it was found in 3.1% of the treated canals. The technical quality of the root canal treatments conducted by the students in this study was comparable to other studies. However, introducing new techniques and armamentaria might improve this quality.

BackgroundThis systematic review aimed to evaluate the clinical performance of core-carrier obturation in endodontic treatment.MethodsKeywords of “(core carrier OR Thermafil) OR (cold lateral condensation OR lateral condensation) OR (warm vertical condensation OR vertical condensation) AND (obturation OR root canal filling) AND clinical study” were searched for all obtainable publications up to year 2017 in the databases of PubMed, ScienceDirect, EMBASE, Scopus and Web of Science. The success rate, short-term postoperative pain, overfilling and adaptation of core-carrier obturation from clinical studies were selected. Reviews, laboratory studies, animal studies and irrelevant reports were excluded.Results1349 relevant articles were identified with 149 duplicated articles removed and 1173 irrelevant articles were excluded after screening. The titles and abstracts of the 19 identified articles were screened in the systematic review. The full texts of remaining articles were retrieved with data extracted for meta-analysis on the success rate, postoperative pain, overfilling and adaptation of obturation. The pooled success rate of core-carrier obturation was 83% (95% CI: 69%-91%). The pooled incidence of 1-day and 7-day short-term postoperative pain were 35% (95% CI: 15%-62%) and 6% (95% CI: 1-35%). The pooled proportion of teeth with overfilling and adequate adaptation of the obturation material were 31% (95% CI: 18%-50%) and 85% (95% CI: 75%-91%), respectively.ConclusionsThe success rate of endodontic treatment using core-carrier obturation was 83%. Short-term postoperative pain was not uncommon (24%). Most teeth (85%) had adequate adaptation using core-carrier obturation material, but a considerable amount of teeth (31%) had overfilling.
“…Si è proceduto alla lenta escavazione della dentina rammollita, evitando la rimozione completa nella zona di proiezione dei cornetti pulpari al fine di poter ridurre al minimo l'insulto diretto all'organo pulpare nonché minimizzare la comparsa di complicanze future a carico della polpa o del periapice 14 . L'utilizzo della metodica di incappucciamento indiretto con MTA ha permesso inoltre, di ridurre il rischio di complicanze endodontiche che avrebbero necessitato delle più moderne tecniche di strumentazione dei canali radicolari al fine di eliminare l'infiltrazione batterica [15][16][17] . Numerosi studi in letteratura hanno dimostrato Figura 9 Dopo sei mesi era già possibile osservare l'inizio della formazione degli apici radicolari.…”
Aim\ud
\ud
In this clinical case an indirect pulp capping was performed, using MTA, at 36 cariously damaged.\ud
\ud
Methodology\ud
\ud
A 7 years old girl, affected by DEA presented a decayed 36 whose radicular formation was still incomplete. After cleaning the carious cavity, MTA was placed as intermediate medication and a temporary filling material was used over MTA. The clinical procedure can be considered safe and simple.\ud
\ud
Results and conclusions\ud
\ud
Because of some problems of hers, this young girl returned after 6 months. The formation of hard tissue was observed and the rx control resulted in a clear evidence of root formation. We performed the final restoration of 36, using composite materials. At 6-months and at 7- years follow- up there aren???t clinical and radiographic signs of pulpar and radicular pathology. In conclusion, MTA seemed to be a material that can be used for the preservation of the pulp tissue vitality. Furthermore it prevented any leakage of the surface below it, even in cases where a lost integrity of the temporary filling material took place
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
