Effectiveness of guided endodontics when accessing root canals containing fiberglass posts: an in vitro study.

The present study aimed to compare the performance of a 3D-endodontic guide (EG) and a conventional technique on the access of root canals containing fiberglass posts. Thirty single-canal lower human premolars were endodontically treated, filled using the single-cone technique, and prepared for fiberglass post luting. The teeth were positioned in the alveoli of human mandibles and cone beam computed tomography (CBCT) examination was performed.

A brief overview of chikungunya-related pain.

Pain is an important symptom associated with the arboviral disease caused by the Chikungunya virus (CHIKV). For a significant number of patients, this symptom can persist for months or even years, negatively affecting their quality of life. Unfortunately, pharmacological options for this condition are limited and only partially effective, as the underlying mechanisms associated with CHIKV-induced pain are still poorly understood.

Direct Discrimination and Growth Estimation of Foodborne Bacteria in Raw Meat Using Electronic Nose.

Evaluation concerning the presence of bacteria in meat products is mandatory for commercializing these goods. Although food bacteria detection is based on microbiological methods, these assays are usually laborious and time-consuming. In this paper, an electronic nose is used to differentiate spp.
