“…The historical focus of surgical attention was too often limited to the eradication of the soft tissue surrounding the root apex, neglecting the removal of the intracanal irritants and proper sealing of the apical foramen. Yet even today, methods do not exist which can thoroughly eliminate all intracanal debris and microorganisms, and materials to establish a predictable apical seal still elude our grasp . Moreover, recent biological investigations have severely challenged long‐advocated techniques and materials used to manage the seal of the resected root end .…”

“… every age should profit by the experience of the preceding ones; but without a record of what has been accomplished each investigator (or clinician) commences a new series of trials (or treatment modalities), and wanders over the same ground in search of truths (or outcomes) which have long been discovered; or adopt theories (or practices) that have been long ago discarded.”* (Note: present author's inserts in italics)  *Patrick JJR.

Adresa za dopisivanjeSelen Küçükkaya DDS Hacettepe University Faculty of Dentistry Department of Endodontics 06100 Sıhhıye -Ankara, Turkey selenkkkaya@yahoo.com Sažetak Svrha: Elektrokemijskom metodom procijenilo se apikalno propuštanje materijala RoekoSeal Automix (RSA) za punjenje korijenskog kanala samostalno i u kombinaciji s gutaperkom. Materijali i metode: Pedeset i dva prednja maksilarna zuba podijeljena su u dvije skupine. U prvoj su korijenski kanali punjeni samo RSA-om, a u drugoj gutaperkom i RSA-om (n = 24 u svakoj skupini). Preostala četiri zuba služila su kao pozitivna i negativna kontrolna skupina. Eksperimentalna jedinica konstruirana je tako da je bila neprekidno spojena na izvor struje. Jedanpostotni kalijev jodid (KI) korišten je kao elektrolit te su zubi uronjeni u otopinu. Bakrene elektrode s provodnim kapacitetom od jednoga miliampera (mA) korištene su kao anode za zatvaranje strujnog kruga. Rezultati su se očitavali ukupno tri tjedna, jedanput na dan, digitalnim voltmetrom spojenim na eksperimentalnu jedinicu. Promjene u količini propuštanja u skupini procjenjivale su se svaki dan t-testom za ovisne uzorke, a razlika između dviju skupina analizirana je t-testom za neovisne uzorke. Rezultati: Razlika u apikalnom propuštanju između dviju eksperimentalnih skupina nije bila statistički značajna (p>0,05). U objema je zabilježeno značajno propuštanje u svim vremenskim intervalima (p<0,05). Zaključak: RoekoSeal Automix samostalno nije se razlikovao u propuštanju od gutaperke punjene njime. Također nije bio potpuno učinkovit u sprječavanju propuštanja.Ključne riječi zub, apeks; korijenski kanal, preparacija; dentalno propuštanje; korijenski kanal, materijali za punjenje; dentalni cementi Sveučilište Hacettepe, Stomatološki fakultet, Zavod za endodonciju, Ankara-Turska Hacettepe University, Faculty of Dentistry, Department of Endodontics, Ankara-Turkey IntroductionThe purpose of endodontic filling is to provide a fluidtight seal at the apex and a total obturation of the root canal system (1). This is commonly achieved using a combination of gutta-percha as a core material and a root canal sealer. Root canal sealers are used to fill the minor interstices between the solid filling material and the wall of the canal. Unless a root canal sealer meets the necessary requirements, it may cause an increase in leakage which leads to endodontic failure (2). To date, there have been lasting attempts to develop better sealers, core materials and obturation techniques to increase the success of root canal treatment. Recently, RoekoSeal Automix (RSA, Roeko, Langenau, Germany), which is a polydimethylsiloxane-based sealer, has been introduced to endodontics. RSA is a silicone elastomer, consisting essentially of polydimethylsiloxane, silicone oil, paraffin base oil, hexachloroplatinic acid (catalyst), zirconium dioxide for the radiopacity. According to the manufacturer, RSA is ready for use in an automix system, does not contain eugenol, biocompatible, radiopaque, well flowing, sets in dry and moist conditions, p...

“…The cause of nearly 60% of endodontic failures is incomplete and improper root canal filling (4). Schilder stated, "Canal filling should include the entire root canal and accessory and lateral canals" (5,6). Some of the most important factors that affect quality of root canal treatment are the anatomy of the canal, the presence of extra canals, and curve in the canal pathway (6,7).…”

In-vitro evaluation of the effect of canal curvature on adaptation of gutta-percha in canals obturated with HEROfill system by CBCT

A hermetic seal of the root canal space following canal preparation is important in endodontics. This study evaluated the effect of canal curve on adaptation of gutta-percha to dentinal walls of canals obturated using the Herofill system. For this in vitro study, 80 mesial roots of mature human first molars with length of 16 mm, curve between 5°and 45°, and no caries or resorption of the root surface were selected. A cone beam computed tomography system was used to evaluate the presence or absence of a gap in the samples. Photographs were taken in three sections: 2 mm above the curve, at the curve and 2 mm below the curve. The gap area was identified using Photoshop and AutoCAD software. Kruskal Wallis and Mann-Whitney tests were used to analyze the data mounted in a castcurve. There were significant differences between the two lateral condensation groups with various curves; roots with more curve had more gaps. When the Herofill and lateral condensation groups were compared without considering the sections and curve, there was a significant difference between these groups and the Herofill group had less gaps. The Herofill system is an alternative to the lateral condensation technique in severely curved canals. (J Oral Sci 53, 43-50, 2011)
