Metalorganic Titanium Treatment to Change Enamel Optical Properties

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 9, September 2026.
ABSTRACT Observational studies have shown that human teeth with higher concentrations of titanium traces have better optical properties. The aim of this study was to investigate how titanium ion infiltration into tooth enamel affects its optical properties by studying the diffusion and reactivity of titanium compounds in tooth enamel and how this ...

Grading in Gerodontology: A Framework

Gerodontology, Volume 43, Issue 3, Page 296-305, September 2026.
ABSTRACT Introduction Understanding and anticipating oral health deterioration in older adults requires more than describing their current oral and general health. Risk factors arising from oral, systemic and social domains strongly influence disease progression, care complexity and the ability to maintain function over time.

Multiple External Invasive Root Resorption and Calcification in Systemic Sclerosis—Case Report

International Endodontic Journal, Volume 59, Issue 9, Page 1963-1978, September 2026.
ABSTRACT Aim There are few reports in the literature of multiple external invasive root resorption (EIRR) lesions in patients with systemic sclerosis (SSc), and an association between root resorption and SSc is not well established. We report the only case that comprehensively illustrates—with the combination of histopathology, cone beam computed ...

Local Sodium Tanshinone IIA Sulfonate Attenuates Periodontal Bone Loss by Modulating Inflammatory, Immune and Osteoclastogenic Signalling

Journal of Clinical Periodontology, Volume 53, Issue 9, Page 1443-1458, September 2026.
ABSTRACT Aim To investigate whether local administration of sodium tanshinone IIA sulfonate (STS) modulates periodontal inflammation, alveolar bone loss, immune response and bone remodelling–related signalling pathways in a ligature‐induced murine model of periodontitis.
