Evaluation of scanning zinc oxide relining impression material for construction of a newly designed CAD CAM maxillary complete denture using an intraoral scanner [PDF]

Alexandria Dental Journal
Introduction: Accuracy of intraoral scanning is challenged by the lack of anatomical landmarks and soft tissue detail. Scanning zinc oxide impressions may enhance reliability by providing a well-defined surface which can be a considered as a part of ...

Effect of saliva isolation and intraoral light levels on performance of intraoral scanners

American Journal of Orthodontics and Dentofacial Orthopedics, 2020
The use of digital models in orthodontics is becoming increasingly widespread. This study aimed to evaluate the accuracy and performance of digital intraoral scanning under 4 different intraoral environmental conditions.Four digital models were acquired with TRIOS intraoral scanner (3Shape, Copenhagen, Denmark) for 50 subjects.

Cheek tooth extraction in geriatric versus non‐geriatric horses

Equine Veterinary Journal, EarlyView.
Abstract Background Age‐related dental changes are major contributors to dental disorders in older horses, and cheek tooth extractions are often required to maintain masticatory function and oral comfort. However, limited information is available on clinical and treatment characteristics in this older patient population.

Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles

Food Bioengineering, EarlyView.
A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...
