This study evaluated the sealing ability of gray MTA-Angelus mixed with propyleneglycol in furcal perforations using a bacterial leakage test. Furcal perforations were created in 30 human mandibular molars using a size 3 round bur The samples were divided randomly into 2 experimental groups (n=10) according to the mixing agent. In G1, the MTA powder was mixed with propyleneglycol, while distill...

They reported It is formed by ventral and dorsal rami of L1-L4 nerve roots with contribution from 12th thoracic nerve (i.e. subcostal nerve). After the anterior rami of the upper four lumbar nerves have supplied psoas and quadratus lumborum segmentally, they form the pleksus in the substance of psoas major.2,3 Juliana Farny et al. reported The lumbar plexus originated from the first four lumbar...

3 F a bstract he purpose of treating furcal perforation is to sea rtificial communication between the endodontic spa nd the periradicular tissue to prevent alveolar b esorption and damage to the periodontal ligame hese complications are not infrequent in cases urcal and/or old perforations, which show a w rognosis than fresh, small, coronal, and apical pe ations. Mineral trioxide aggregate (MTA...

The aim of this study was the comparative evaluation of inflammatory reactions and tissue responses to four growth factors, or mineral trioxide aggregate (MTA), or a zinc-oxide-eugenol-based cement (IRM) as controls, when used for the repair of furcal perforations in dogs' teeth. Results showed significantly higher inflammatory cell response in the transforming growth factorβ1 (TGFβ1) and zinc-...

The aim of this study is to evaluate the microleakage of repair materials MTA, IRM, and Biodentine applied on furcal perforations with different diameters. One hundred and forty extracted human teeth were used in this study. The teeth were divided into 2 main groups (60 teeth in each) which were then divided into 3 subgroups (n = 20). The remaining 20 teeth were divided into 2 groups (10 in eac...
