introduction : furcal perforations are one of the most challenging causes of endodontic failures. several materials including mta have been used for non surgical repair of these perforations. the aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using root mta and proroot mta. materials and methods: this in vitro study was conducted on 54 prima...

A new species belonging to the tribe Thalassaphorurini, Thalassaphorura problematica sp. n., is described from Northeast China. The new species is closest to the large genus Thalassaphorura by its simple vesicles in PAO and its furcal rudiment, but it does not fit the definition of the genus by the absence of chaeta d0 on head, the number of chaetae in the distal whorl of tibiotarsi and the lab...

AIM To compare the ability of Portland cement and mineral trioxide aggregate (MTA) to prevent coronal leakage through repaired furcal perforations in molar teeth. METHODOLOGY The pulp chambers of 36 human mandibular molar teeth were accessed and the root canal orifices were located. The roots were horizontally sectioned in the middle third. Composite resin was used to fill the root canal orif...

Our results are the first insight into groundwater copepods of Polish Lowland. The sampling was conducted in 28 wells north-eastern Poland, and Copepoda were present 16 wells. We have identified six species one Cladocera. classified four as stygophiles—Eucyclops serrulatus, Diacyclops bisetosus, crassicaudis, Cyclops furcifer. These frequently found studied different regions often high numbers,...

One of the most important indications for guided tissue regeneration (GTR) treatment is class II furcation lesion. However, periodontal regeneration of this type of defect, although possible, is not considered totally predictable, especially in terms of complete bone fill. Many factors may account for variability in the response to regenerative therapy in class II furcation. The purpose of this...

The present report reviews the diagnostic and treatment challenges of a mandibular molar with previous root canal treatment and signs of a procedural mishap, i.e. furcal radiolucency and localized swelling of the gingival margin in which a sinus tract was present. By tracing the sinus tract, it became evident that the lesion originated from the furcation area, not the root apices. This case was...
