Clinical Features and Dental Pathologies in Maxillary Sinus Fungal Balls and Odontogenic Sinusitis

open access: yesThe Laryngoscope, EarlyView.
This international, multicenter study compared clinical and dental characteristics of maxillary sinus fungal balls (MSFB), odontogenic MSFB (MSFBO), and odontogenic sinusitis (ODS). When MSFB and MSFBO were compared, MSFBO was associated with extruded root canal material and dental implant protrusion; when MSFBOs and ODS were compared, ODS was ...

Using Participatory System Dynamics Approaches to Improve Community‐Based Oral Healthcare Delivery: A Case Study of the ElderSmile Program

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT This study leveraged system dynamics approaches to improve community‐based oral healthcare delivery via the ElderSmile program. Insights and inferences from focus groups and key informant interviews with older adults and their service providers, respectively, were integral to understanding feedback mechanisms articulated in participatory ...

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

open access: yesWildlife Biology, EarlyView.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

open access: yesHigh Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro‐CT Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.
