Obturation with gutta percha of greater taper
… master gutta percha point; (Group 4) single cone obturation using a DiaPro 0.06 taper master gutta percha point. Dye leakage was measured after the teeth were rendered transparent. There was no statistically significant difference among the groups for the presence of leakage (Chi Square, p = …

V- Shaped Defects – Epidemiology, Clinical Picture and Obturation Opportunities // Клиновидни дефекти – епидемиология, клинична картина и възможности за обтуриране
Wedge-shaped defects, such as non-carious disease of the hard dental tissues, are observed in a small percentage of the patients studied. They are of interest to the dentist because they lead to some disorders associated with increased sensitivity of the affected teeth, eating disorders, plaque …

Density of Gutta Percha by Weight in Straight Root Canals and Curved Root Canals after Single Cone, Cold Lateral, and Warm Vertical Condensation
… of gutta percha following three different obturation techniques using two split-tooth models. One split-tooth model was constructed with a straight rooted maxillary incisor and the other with the curved palatal root of a maxillary molar. Each tooth was obturated using single cone, cold …

ULTRASONIC ROOT-END PREPARATION AND SEALING ABILITY OF CONVENTIONALLY-SETTING GLASS IONOMER CEMENTS IN SURGICAL ENDODONTICS
… cavities with and without cracks and their obturation efficiency were evaluated. The teeth were immersed in Indian ink and cleared. Apical leakage was measured and obturation efficiency was scored. The presence of cracks, originating from the root canal, negatively influenced the seal and …

The Effect of Chlorhexidine Gluconate as an Endodontic Irrigant on the Apical Seal: Long-term Results
… gluconate, and dried using paper points. Obturation was accomplished using lateral condensation and one of three endodontic sealers: Roth's 811, AH26, or Sealapex. Post-obturation apical leakage was measured at 270- and 360-day observation periods using the fluid filtration method. Using …

Retreatability of root canals obturated using a bioceramic sealer and gutta percha
… achieving working length and apical patency when obturation is done with the master GP placed at working length and when it is short by 3mm. The time it took to achieve these parameters when it was possible to achieve them was also determined. The role of XP Endo Finisher R, a supplementary …

Application of Preformed Metal Crowns on Class II Carious Lesions on Primary Molars /// Приложение на преформирани метални коронки при втори клас кариозни лезии на временни молари
… put some limits concerning the proper choice of obturation material. Nowadays the most commonly used filling material for primary molars restorations are GIC. They have a very good biological activity (fluor releasing potential) to hard tooth tissues, provide chemical bond with the tooth’s …

Effect of the GentleWave System on dentin microhardness and sealer penetration: an in vitro study
… (Group G). Following irrigation and obturation with AH Plus sealer and gutta percha using cold lateral compaction, transverse slices were obtained at 2-, 5-, and 8-mm distances from the apex. Assessment methods included microhardness testing and scanning electron microscopy (SEM). …

ASSESSMENT OF ANTIBACTERIAL EFFECT AND FLOWABILITY OF BIOCERAMIC SEALER MODIFIED WITH BaTiO3 NANOPARTICLES
… BC+ BaTiO3-5%, BC+ BaTiO3-10%) were used for obturation. Untreated teeth were used as positive control. Specimens with BaTiO3 particles were subjected to compression cyclic loading to activate the piezoelectric charges and resemble mastication forces. Cell viability (CFU/mL) was used to …

The Effect of Root Canal Cleansing on the Retention of Glass Fiber-reinforced Posts
… millimeters. Endodontic instrumentation and obturation was performed. Post space was prepared to a length of ten millimeters. Post spaces were irrigated using one of two solutions: MTAD for five minutes and 17% EDTA for one minute. No irrigation was used in the control group. After …

pH Change Following Smear Layer Removal and Final Rinse with 95% Ethyl Alcohol Using Calcium Hydroxide Medicament or BC Sealer
… alcohol using Ultracal XS, Calasept Plus, or obturation with BC sealer. Methods: 80 single rooted extracted human teeth were decoronated with a standardized root length of 15mm. All root were instrumented to size F4 using the ProTaper Gold file system. Defects were made on the facial and …

In Vitro Accuracy of the E-PEX Electronic Apex Locator Compared to the Root ZX II in the Presence of Various Irrigation Solutions
… Determining the end point of instrumentation and obturation is one the most important aspects of a well-done non-surgical root canal treatment (NSRCT). This reference point determines the working length, and is commonly calculated with the aid of an electronic apex locator (EAL), which accurately …
