The aim of this study was to evaluate the effectiveness of gutta-percha and Resilon in filling lateral root canals by using the Obtura II system. Root canals of artificial teeth were prepared using a standard protocol, and lateral canals were made in three thirds of the root canal. The root canals were filled with either Obtura gutta-percha (OB), Endo-points flow gutta-percha (ED), or Resilon (...

Objective: Chloroform is an organic solvent extremely effective in dissolving the gutta-percha, but it is a potential carcinogen. The aim of this study is to compare the effectiveness of different alternative solvents with ability to dissolve gutta-percha that can be regarded a practicable alternative to chloroform. Materials and Methods: Stainless steel ring molds were used to create 50 gutta-...

Aims: To compare and evaluate the apical sealing ability of Guttaflow, Thermoplasticized Gutta percha and Lateral Compaction technique using dye penetration method, Robertson’s clearing technique and triocular stereomicroscopy. Methods: A total of eighty extracted human mandibular molars were decoronated, sectioned and instrumented with rotary protapers size F1. Teeth were randomly divided into...

The aim of this study was to evaluate the efficacy of ProTaper and K3 in the removal of gutta-percha during root canal retreatment in comparison with hand Hedstrom files. Time of gutta-percha removal and amount of apically extruded debris were also evaluated. Sixty extracted single-rooted anterior teeth and premolars were instrumented and obturated with laterally condensed gutta-percha techniqu...

statement of problem: the bond strength of root canal sealers to gutta-percha seems to be an important property for maintaining the integrity of the apical seal which can result in reducing apical microleakage. purpose: the purpose of the present study was to compare the tensile bond strengths of four types of root canal sealers to gutta–percha. this study measured the maximum forces needed to ...

BACKGROUND Mature teeth with chronic apical abscesses characterized by intermittent discharge of pus through an associated sinus tract. This communication between oral mucosa and periapical inflammation is challenging for the sealing ability of root canal obturation material. Therefore, the study aim was to compare the outcomes of endodontic treatment using mineral trioxide aggregate (MTA) ceme...

This study was done to evaluate new manufactured rotary spreaders one made from stainless steel material and second from nickel titanium and compared them with conventional finger spreader for their affect on the amount of gutta percha (in mg) that can be applied to fill the root canal and evaluation of apical extension of first, second, third and fourth auxiliary gutta percha cones for the sta...

Experiments were conducted to determine the effects of thermal pulp testing agents on the human dental pulp. Histological evaluation of the pulps of premolar teeth to which heated gutta-percha had been applied for up to 10 s revealed no evidence of injury. Teeth to which carbon dioxide (CO=) snow was applied for as long as 5 min were found to have structurally intact pulps. When the thermal tes...
