Gingival Recession, Oral Hygiene and Associated Factors Among Tanzanian Women. [PDF]
Females are generally more motivated with regard to oral hygiene practices and thus brush their teeth more frequently than males. To determine the prevalence of gingival recession, oral hygiene status, oral hygiene practices and associated factors in ...

An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

Biofilm Implication in Oral Diseases of Dogs and Cats
The importance of biofilm in disease processes in humans and animals is now widely recognized. In animal species, the risk of infection is probably greater than the risk in humans. This is due to the difference in animal housing and living environments –

Biocultural Implications from Scanning Electron Microscopy of Prehistoric Human Dental Calculus, Ohio [PDF]
Poster: 3rd Place (The Ohio State University Edward F. Hayes Graduate Research Forum)Dental calculus, though it provides a unique calcium reservoir of bacteria and dietary debris seldom preserved elsewhere in the archaeological record, is an overlooked ...

Polyamide 12 powder nanoadditivated with laser‐synthesized silver nanoparticles is deposited and sintered on polymer parts via EPA‐PBF‐LB/P. The thin surface coating (140 µm) inhibits E. coli and S. aureus bacteria growth and significantly increases the UV light absorption, whereas the mechanical and thermal properties remain unchanged due to minimal ...

Statistical validation of a deep learning algorithm for dental anomaly detection in intraoral radiographs using paired data [PDF]
This article describes the clinical validation study setup, statistical analysis and results for a deep learning algorithm which detects dental anomalies in intraoral radiographic images, more specifically caries, apical lesions, root canal treatment defects, marginal defects at crown restorations, periodontal bone loss and calculus. The study compares
