“…However, this technique showed failures such as overfilling, possibility of fracture of the instrument, and displacement of the cone, and it was impossible to use in curved canals (8). In 1983 Tagger et al (9) The filling technique with thermoplasticized guttapercha in a special syringe was introduced to facilitate the completion of the conduit and has been advocated by several authors (10)(11)(12)(13). The injectable thermoplasticized gutta-percha systems are used by the action of an electric heater of low intensity that produces uniformity of the material being injected into the root canal with syringe pressure.…”

The aim of this study was to investigate the apical leakage of roots filled by three different gutta-percha techniques: lateral condensation, Tagger's hybrid and E&Q Master. Forty-two extracted singlerooted teeth were used. The coronal part of each tooth was removed and the root received biomechanical preparation using a 60-K file. The roots were randomly divided into three groups according to the technique of filling the root canal: Group I, lateral condensation; Group II, Tagger's hybrid; Group III, E&Q Master. The roots were submitted to dye leakage test with Rhodamine B for 7 days, using vacuum during the initial 30 min. The teeth were sectioned longitudinally and the leakage was measured in a linear fashion from apex to crown. Statistical analysis indicated that lateral condensation and E&Q Master techniques showed lower leakage than Tagger's technique (P = 0.0016). However, statistically no difference was found between lateral condensation and E&Q Master system techniques. (J Oral Sci 51, 593-599, 2009)

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 cold lateral condensation technique is still, one of the most frequently used techniques in endodontics. 4 However, its ability to replicate the internal surface of the root canal has been questioned. Voids, incomplete fusion of guttapercha cones and lack of surface adaptation have been addressed.…”

Aim:To compare the apical seal of lateral condensation technique, thermafil and one-step by using this model. Materials and methods:A two-chamber bacterial microleakage model using E. faecalis as microbial marker was used for evaluation of the leakage. Bacterial penetration was monitored over a 60-day period. Leakage was recorded when turbidity was observed in the lower chamber.Results: After comparing the bacterial penetration values, total penetration was observed 45% in lateral condensation technique, 80% in thermafil and 75% in one-step. There was no significant difference between groups after 60 days; however, the microleakage in lateral condensation group was seen later than one-step and thermafil. Conclusion:Thermafil and one-step obturator can be advocated as effective obturation techniques for achieving predictable success in endodontic therapy.Clinical significance: Thermafil and one-step obturator are suitable devices for obturation.
