The purpose of this study was to evaluate the movement of gutta-percha into lateral grooves and depressions in the apical 7 mm of a root canal by using the System B Heat Source for the continuous wave of condensation and the Obtura II for the backfill. A split-tooth model was constructed with lateral grooves and dentin depressions prepared at 1, 3, 5, and 7 mm from working length (WL). The stud...

Molecular dynamics simulations have been carried out to investigate the onset of surface condensation. On surfaces with different wettability, we snapshot different condensation modes (no-condensation, dropwise condensation and filmwise condensation) and quantitatively analyze their characteristics by temporal profiles of surface clusters. Two different types of formation of nanoscale droplets ...

objective: the aim of this study is to measure the effect of different condensation pressure on the microleakage of mineral trioxide aggregate (mta).  methods: this study was an invitro study. a total of 55 single rooted straight-canal human extracted sound teeth free of cracks or calcification were selected. teeth were sectioned from cej region at 3 mm above the root apex. remaining specimens ...

Posterior maksiller bölgede kemik hacmi ve kalitesinin yetersiz olması nedeniyle implant yerleştiriminde zorluklarla karşılaşılabilmektedir. Bu bölgelerde başarılı implant yerleştirimi için krestel yaklaşımla sinus tabanının yükseltilmesi başarı ile uygulanmaktadır. Osteotom adı verilen aletler ile lateral duvar genişletilir ve kondense edilir. Bunu sinus tabanının yukarı doğru kırılarak itilme...

The radix entomolaris is an anatomical variation characterized by the presence of additional root located in distal-lingual region mandibular molars. An accurate diagnosis necessary to plan and institute effective endodontic therapy for teeth with this condition. aim report was present three cases management permanent first molars using contemporary technical resources. For diagnosis, periapica...

a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...

introduction : one of the key factors in successful endodontic therapy is to adequately fill the root canals. the aim of this in vitro study was to compare the quality of four different root canal obturation techniques: cold lateral condensation (clc), warm vertical condensation (wvc), obtura ii (oii) and gutta flow (gf) by using micro-computed tomography (micro ct). materials and methods: a to...

the nanoparticles of ti and tio2 have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, pigment and cosmetic manufacturing and biomedical engineering. through this project, a one-step bulk synthesis method of electromagnetic levitational gas condensation (elgc) was utilized for the synthesis of monodispersed and crystalli...
