A multicenter, controlled, randomized trial of home‐applied dual‐light photodynamic therapy in stage I to III periodontitis (LumoNorth2022 study)

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis is a widespread, chronic infection‐triggered inflammatory condition in which professional supportive periodontal care (SPC) and daily oral hygiene form the backbone to reduce the disease activity. Light‐based treatments have shown promising antibacterial effects, but their potential for routine home use has not been ...

Associations between periodontal inflammation and OHIP‐14 scores: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background More evidence is needed to assess the association between periodontitis and Oral Health‐Related Quality of Life (OHRQoL) quantitatively. We hypothesized that periodontal inflammation is correlated with a worsening in quality of life and aimed to test this in this study.

Cement production with pozzolans from residual tropical soils formed from paragneiss with a high silicon oxide content

Dyna, 2020
The manufacture of cement demands a lot of energy and gives off large amounts of CO2. Calcined clays need less energy and emit water instead of CO2, which has drawn attention to them, especially those rich in kaolinite.
