introduction: there are various studies looking at the effects of formocresol (fc) and mineral trioxide aggregate (mta) on pulpotomy of primary molars. this is a systematic review of literature comparing the success rates of mta and fc in pulpotomy of primary molars. materials and methods: the study list was obtained using pubmed, embase, scopus, science citation index, iran medex, google schol...

introduction: this study was carried out to compare the capability of k-files with mtwo rotary file in terms of negotiation as well as depth of penetration in second mesiobuccal (mb2) canal of maxillary first molar. materials and methods: a total of 32 mb2 canal of maxillary first molars having different root curvatures (not more than 30 degree) and root lengths were selected and then detected ...

a mandibular first molar requiring root canal therapy was found with five canals, three mesial canals, and two distal canals. initially, four canals (mesiobuccal, mesiolingual, distobuccal, and distolingual) were identified. the mesiobuccal and mesiolingual canals were found in their normal locations, and a fifth canal was noted between these two. this case demonstrates a rare anatomical config...

thorough knowledge of the morphology and internal anatomy of the root canal system is essential, because it determines the successful outcome of endodontic treatment. the main goal of endodontic treatment is to prevent apical periodontitis and/or to promote the healing of periapical lesion. presence of two canals or roots on the palatal side of the first maxillary molar has rarely been reported...

background : gestational trophoblastic neoplasia (gtn) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. many attempts have been made to improve follow-up procedures, but no studies have evaluated human chorionic gonadotrophin (hcg) as a post treatment indicator. thus we aimed to know β-hcg variability in post treatment pregnancies.   method...

conclusions it was observed that the success and survival rate of maxillary molar immediate implant was relatively high and similar to those of conventional delayed implants. results immediate implants were most frequently used for incisor and premolar sites and there is very little data available on immediate implantation in the molar area. in this research, we reviewed all the existing papers...

the influence of increasing the sio2/k2o molar ratio on the electrochemical action of a waterbornepotassium silicate zinc-rich coating was investigated by means of electrochemical impedancespectroscopy (eis) and corrosion potential (ecorr) measurements. the eis results showed thatincreasing the sio2/k2o molar ratio in the range of 3.135 to 5 by the addition of nano-sio2 to theresins improved th...

background: distinction of hydatidiform moles (hms) from non-molar abortions and sub-classification of hms are important for clinical practice; yet, diagnosis based solely on morphology is affected by interobserver variability. the objective of this study was to determine the role of dna flow cytometry in distinguishing molar from non-molar pregnancies. materials and methods: this retrospective...

introduction: mandibular first molar is the most important tooth with complicated morphology. in finite element (fe) studies, investigators usually prefer to model anterior teeth with a simple and single straight root; it makes the results deviate from the actual case. the most complicated and time-consuming step in fe studies is modeling of the desired tooth, thus this study was performed to e...
