conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

introduction: enlargement of the root canal may potentially affect efficient smear layer (sl) removal. the aim of the present in vitro study was to compare sl removal following canal preparation with two different sizes/tapers by means of scanning electron microscopy (sem). methods and materials: a total of 50 extracted human mandibular premolars were decoronated. the teeth were randomly divide...

AIM The aim of this in vitro study was to evaluate if there is any significant difference in apical leakage when gutta-percha is removed immediately after obturation for postspace preparation or after a week. MATERIALS AND METHODS Two commonly used sealers AH26 and tubliseal were used in four groups each consisting of 20 teeth each. The tooth was sectioned at the amelocemental junction to lea...

OBJECTIVE Aim of the present study was to evaluate the retreatability and reestablishment of apical patency of two calcium silicate-based sealers, TotalFill BC Sealer (BCS) and mineral trioxide aggregate Fillapex (MTA F), versus AH Plus, when used in combination with Gutta-percha (GP). MATERIALS AND METHODS The canals of 54 single-rooted anterior teeth were instrumented and filled with GP/AH ...

canal) in the extracted permanent maxillary first molars of a Sulaimani population. An ex vivo study on 180 extracted permanent maxillary first molars was conducted and the floor of the pulp was clearly exposed. The canal orifice was examined clinically by the aid of a chelating agent and magnifying lens. Patency of each canal was established by a no.10 k-type file. The results showed that 23.3...

conclusion hsg is considered to have a high sensitivity and specificity. hsg and laparoscopy are not alternative, but are the complementary methods in the examination of no tubal patency. results the sensitivity and specificity of hsg on bilateral tubal patency or no bilateral tubal patency were 92.1% and 85.7% respectively. the positive and negative predictive values were 97.2% and 66.7%, and ...

introduction: in a prospective blind study, we evaluated sonohysterography (shg) as a diagnostic tool for uterine cavity and tubal patency and compare shg with laparoscopy in tubal patency and hysterosalpyngography for uterine anomaly as gold standard methods. material and methods: 76 infertile patients undergone shg and hsg and laparoscopy and comparison between the different diagnostic techni...
