“…Various bacteria have been used in microleakage studies [17][18]21,25 . However, there is a focus on E. faecalis because of its resistance [19][20]22,24 , survival in nutrient-poor areas over long periods 26 , and association with persistent chronic periapical lesions 27 . The results demonstrated that the mean time of leakage in samples in the experimental period was 21 days.…”

“…Most studies have used single-rooted teeth [17][18][19][20][21][22][23][24] . The use of molars was proposed due to their high incidence in endodontic treatment, and the choice of the distobuccal root of the maxillary molar was based on a standardization criterion 9 .…”

“…Various methods have been employed in the evaluation of the obturation of root canals: dye leakage [12][13] , fluid filtration [14][15][16] , and bacterial leakage [17][18][19][20][21][22][23][24] . The option for bacterial leakage is justified since it is an experimental model that is simple and easy to replicate.…”

Aim: To compare bacterial leakage in root canals obturated with the modified single-cone, lateral condensation, and continuous wave of condensation techniques. Methods: Distobuccal root canals of maxillary molars were shaped up to ProTaper F2 and obturated with modified singlecone, lateral condensation or continuous wave of condensation technique. Two-chamber bacterial model using Enterococcus faecalis was employed for bacterial leakage evaluation for 30 days. The chi-square test was applied to evaluate differences between turbid and non-turbid samples, and the Kruskal-Wallis test was used for evaluating the time necessary for microleakage. A significance level of 5% was set for all analyses. Results: The modified single-cone technique showed leakage in 73.3% of samples, lateral condensation in 66.6%, and continuous wave of condensation in 53.3%, but there were no significant differences among the groups (p>0.05). Conclusions: It can be concluded that the modified single-cone technique shows similar sealing efficacy to that of lateral condensation and continuous wave of condensation technique.

“…1,38,39 However, other investigations have indicated that some obturation systems like Guttaflow and Resilon cones with Epiphany provide better seal against microbial leakage than gutta-percha/AH-plus sealer. 40-43 , However, greater amount of microleakage has been reported with Resilon compared to gutta-percha/zinc oxide eugenol and AH-plus.…”

“…Resilon™ has been subjected to numerous studies to determine if its sealing abilities are superior to GP, and these studies have utilised various methods of assessing leakage. A recent bacterial leakage study by Kangarlou et al 84 noted no significant differences between Resilon™/Epiphany™ and GP/AH26™. Oliveira et al 85 also conducted bacterial leakage studies with GP and various sealers as well as with the Resilon™/Epiphany™ system.…”

During root canal treatment, the root canal of a tooth is prepared, disinfected and filled. Alkaline materials have been used in endodontics for many years mainly as medicament pastes rather than for obturation of the root canal system. Calcium hydroxide, the most commonly used alkaline material in dentistry, releases hydroxyl ions which cause disinfection of the root canal system. The first part of this thesis examines the use of calcium hydroxide in non-aqueous solvents and compares this to calcium hydroxide in traditional water-based solvents. The novel use of anthocyanin as an indicator allowed tracking of diffusion of hydroxyl ions through root dentine.The discovery of calcium hydroxide-induced polymerisation of certain organic compounds such as glycerol to form a hard setting alkaline cement opens the possibility of using these materials for short or long term obturation of the root canal. In the second part of the thesis, a bacterial leakage study was carried out to compare the sealing capabilities of various root filling materials including this novel hard-setting alkaline cement as well as mineral trioxide aggregate (MTA) cements, which release calcium hydroxide from their setting reaction, and traditional epoxy resin sealers.In the third part of the thesis, the root fillings were then assessed in terms of their removability, a parameter which is relevant both for post space preparation and in the event that retreatment is required. Materials were tagged with a fluorescent label and then confocal laser scanning microscopy was used to assess the extent of remnant material and the cleanliness of the root canal walls.The results from Part 1 indicated that hydroxyl ion release into root dentine is greater with non-aqueous solvents, resulting in a sustained level of high alkalinity within the root.This feature should provide longer disinfection and should therefore reduce the number of inter-appointment visits clinically. In Part 2, bacterial leakage studies demonstrated that alkaline cements had greater sealing capabilities than commonly used epoxy resin sealers. This is most likely due to the antibacterial actions of hydroxyl ions released from alkaline cements. In Part 3 of the thesis, with regards to removability using rotary instrumentation, the novel hard-setting calcium hydroxide cement was more easily removed than MTA 3 cements or epoxy resin sealers, with the latter coating half of the canal walls after instrumentation.Overall, the findings from this thesis show that while calcium hydroxide pastes based on water are an integral and long standing part of root canal disinfection, the potential use of calcium hydroxide in dentistry is wider than its current applications. The research from this thesis shows that calcium hydroxide in non-aqueous solvents may be suitable for use as a disinfecting medicament and that when incorporated into a cement it may have properties that are well suited to being used in obturation of the root canal.4
