We developed a clinical probe capable of acquiring simultaneous short wavelength infrared (SWIR) reflectance and occlusal transillumination images of lesions on tooth proximal and occlusal surfaces to reduce the potential of false positives. The dual probe is 3D-printed and the imaging system uses a Ge-enhanced camera and fiber-optic light sources that use SWIR light at 1300-nm for occlusal transillumination and SWIR 1450-nm light for reflectance measurements. The purpose of this study was to test the performance of the probe on extracted teeth prior to commencing clinical studies. The dual probe was used to image extracted teeth with proximal and occlusal lesions. SWIR images of each tooth were compared with micro-CT images to assess performance.

Erosive tooth wear (ETW) is a prevalent oral condition with varying etiology, including erosion, abrasion, abfraction, and attrition. It is reported in the literature in different nomenclatures, hindering the ability to identify the emerging trends and influential scholarly works and bodies within this field. Using a bibliometric analysis approach, this study aims to evaluate the trends, themes, and productivity of the research on ETW condition while respecting its different terminologies.

Article Synopsis
- Chronic inflammation is linked to various diseases and is characterized by prolonged immune cell activation, resulting in tissue damage.
- Despite the effectiveness of current anti-inflammatory medications, they often have side effects due to non-specific targeting.
- Nanoparticle drug delivery shows promise for targeted therapy in inflammation, but improvements are needed to specifically target different immune cell types for enhanced therapeutic effects.
CBCT analysis of the incidence of maxillary lateral incisor dens invaginatus and its impact on periodontal supporting tissues.

Department of Stomatology, Beijing Friendship Hospital, Capital Medical University, Beijing, China.
Background: Dens invaginatus is a developmental abnormality originating from tooth development, including coronal invaginatus and radicular invaginatus. The reported incidence varies greatly due to diagnostic techniques, classification criteria and race. The incidence of dens invaginatus in China was not clear, and the impact of dens invaginatus on periodontal support tissue were rarely reported.

Objective: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes of adhesion according to the FDI criteria. The primary outcome was the retention loss of the restorations, while the secondary outcomes included marginal staining, marginal adaptation, post-operative sensitivity and tooth vitality, recurrence of caries erosion and abfraction, and tooth integrity, all evaluated according to the FDI criteria.
Materials And Methods: In this study, the SBU Adhesive was applied to 246 NCCLs of 25 patients using different modes of adhesion: Self-etch (SE), selective-enamel-etching (SLE), and etch-and-rinse (ER).
