Green synthesis of benzimidazole derivatives by using zinc boron nitride catalyst and their application from DFT (B3LYP) study.

A new zinc-based boron nitride (Zn-BNT) material was synthesized from boron nitride and zinc acetate in 95% yield. The morphological and spectroscopic properties of Zn-BNT were elucidated by SEM, XRD, BET, DSC-TGA, and FT-IR. Zn-BNT catalyzed the synthesis of benzimidazoles () through a reaction between -phenylenediamine and different aromatic aldehydes under microwave conditions for 15 min.

Evaluation of Oral Pentoxifylline in the Management of Oral Submucous Fibrosis - An Ultrasonographic Study.

Aim And Objective: To evaluate the therapeutic efficacy of oral pentoxifylline in the treatment of oral submucous fibrosis (OSMF) patients by assessing the clinical symptoms such as burning sensation, mouth opening, and submucosal layer thickness and echogenicity using ultrasonography, both pre- and post-operatively.

Materials And Methods: Thirty study subjects were included in the study and divided into two groups in single-blind randomized manner, oral pentoxifylline and dexamethasone group. Burning sensation, mouth opening, ultrasonographic submucosal thickness, and echogenicity were recorded both pre- and post-operatively.

Primary juxtacortical chondrosarcoma of mandibular symphysis: Unique and rare case report.

Juxtacortical chondrosarcoma (JC) is a rare, malignant, cartilage-forming tumor arising from the external bone surface. It mainly involves long bones and very rarely involves maxillofacial skeleton. Chondrosarcoma in general accounts for about 10-20% of all bone neoplasm, of which only 1-3% is involved in maxillofacial skeleton.
