22. Extraction of impacted mandibular third molar with cemental hyperplasia using buccal cortex osteotomy of the mandibular ramus

Abstract

Impacted mandibular third molar extraction is one of the most frequent procedures performed in the field of oral surgery. Oral surgeons sometimes face cases that cannot be extracted using the conventional procedure because of atypical tooth structure or irregular tooth position in the mandible. Here, we report an unusual impacted third mandibular molar with atypical root form, which was extracted by buccal cortex osteotomy of the mandibular ramus. A 42-year-old Japanese female presented with a complaint of discomfort in the left molar region. Radiographical examination showed an impacted third molar with a mushroom-like root overlapping the mandibular canal. This lesion was radiographically diagnosed as cemental hyperplasia. The tooth could not be extracted using the conventional procedure, and buccal cortex osteotomy was applied. Briefly, bones necessary for extraction were removed once from the mandibular ramus. After extraction, the bony fragment was repositioned in the original position. The patient experienced no postoperative complications such as nerve paralysis, mandibular angle fracture, and infections. Buccal cortex osteotomy is a simple and easy technique to extract impacted mandibular third molars that cannot be extracted by conventional methods.

Subjects
Metal bonding -- Research, Chemistry
Abstract

It has been possible to prepare metal-metal bonded chain complexes using a PtII-Ag+ dative bond. This research showed a novel helical 1-D chain complex and a linear pentanuclear complex with alternating PtII and Ag+ ions.

27. The first examples of platinum(II)-cadmium(II) bonds: the role of strong field ligands in making dative Pt->M bonds

Abstract

Research was conducted to examine the first examples of platinum(II)-cadmium(II) bonds and to determine the role of strong field ligands in making dative Pt->M bonds. Results provide evidence that square-planar Pt(II) in a strong ligand field generates strong Pt->Cd dative bonds. It was observed that (Pt(phpy)2) and (Pt(thpy)2) react also with AG+ to yield compounds with Pt->Ag dative bonds.

40. A cyclic tetramer of [Ag(1,4,7‐trithiacyclononane)]+, cyclo‐tetrakis(μ‐1,4,7‐trithiacyclononane‐κ3S1,S4,S7:κS1)tetrasilver(I) tetrakis(trifluoromethanesulfonate) nitromethane disolvate

Author

Abstract

(1,4,7‐Tri­thia­cyclo­nonane)silver tri­fluoro­methane­sulfonate crystallizes in a tetrameric form from nitro­methane, to give the title compound, [Ag4(C6H12S3)4](CF3SO3)4·2CH3NO2. The complex cation consists of four [AgL]+units (Lis 1,4,7‐tri­thia­cyclo­nonane), with four Ag—S—Ag bridges forming a cyclic tetramer. The almost planar Ag4S4ring takes an octagonal form.

Abstract

Background/aim: Few studies have performed magnetic resonance (MR) imaging on live animals. The aim of this study was to perform 7T MR microimaging of the temporomandibular joint (TMJ) multiple times in the same living mice with malocclusion, and to compare between MR imaging and histopathological findings., Materials and Methods: Mice were examined by MR imaging at 3-4, 6 and 12 weeks following the attachment of a metal tube on the left mandibular incisor. Histopathological examination was done at 3, 6 and 12 weeks., Results: The detailed structure of the TMJ was evident from MR microimaging. The histopathological examination showed some changes in the cartilage, but no changes in the bone structure of these mice., Conclusion: We successfully performed multiple 7T MR imaging in living mice. Even if the TMJ showed no obvious changes on MR images, minute changes may be present in the cartilage., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.

Abstract

We constructed an arm holder for muscle exercise from a forearm-shaped plastic shell and magnetic resonance (MR) imaging position markers and determined the echo time (39 ms) for T₂-weighted spin-echo MR imaging from T₂values of the exercised (50 ms) and resting (32 ms) muscle at 0.2 tesla. The smallest detectable muscle was the extensor digiti minimi muscle (cross-sectional area 25 mm²). This combination could be useful to monitor finger exercise in patients undergoing physical therapy.
