Impact of bismuth oxide on structural, optical and gamma-ray shielding properties of calcium-sodium-borate glasses.

In the present study, we have prepared six glass samples of bismuth borate using the melt-quenching method with the composition (70-x)B2O3-10CaO-20Na2O-xBi2O3; x = 0, 3, 6, 9, 12 and 15 mol%. The density of the prepared glasses was determined using Archimedes principle. The X-ray diffraction patterns provide confirmation of the amorphous nature of the prepared samples, whereas the Fourier transform infrared measurements pointed to the existence of structural units like BO3, BO4, BiO3 and BiO6 within the glass network.

Assessment of Knowledge and Attitude Regarding Teledentistry Among Dental Professionals: A Cross-Sectional Study.

Background: Modern technologies have led to the development of new tools, practices, and digital techniques. However, their use in public health to provide adequate oral health facilities to the community is limited. One of the facilities that can help provide better oral health with minimal cost is teledentistry.

Assessment of Posterior Pharyngeal Airway Changes After Orthognathic Surgery Using Barium Sulfate.

Introduction:  Obstructive sleep apnea (OSA), caused by airway narrowing, is likely to occur if the mandibular plane to hyoid distance is greater than 15.4 mm and the posterior airway space (PAS) is less than 11 mm. OSA may be caused by mandibular deficit, bimaxillary retrusion, increased lower facial height, extended soft palate, a large tongue base, and a posteroinferiorly positioned hyoid bone.

Comparative Evaluation of Postoperative Pain in Primary Teeth Obturated With Zinc Oxide Eugenol versus Metapex: A Randomized Clinical Trial.

The fundamental objective of pulp treatment is to preserve the integrity and health of oral tissues. Pulp necrosis or irreversible pulpitis is the key indication for performing pulpectomy in primary teeth. It can be performed as a single-visit or multi-visit procedure using suitable obturating material.
