Does timing of systemic antibiotics influence periodontal treatment outcomes? A randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The aim of this study is to determine whether the timing of metronidazole (MTZ) and amoxicillin (AMX) administration, relative to scaling and root planing (SRP), influences the clinical and microbiological outcomes of periodontal treatment.

Diagnostic accuracy of transmucosal probe visualization for peri‐implant mucosal phenotype assessment: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background This study evaluated the diagnostic accuracy of visual assessment of mucosal transparency using a standard periodontal probe (VAT) to differentiate between thin and thick peri‐implant mucosal phenotypes, compared to horizontal transmucosal probing (HTP).

Electrolyzed saline as an alternative to chlorhexidine: Antimicrobial and biofilm volume outcomes in a 4‐day non‐brushing randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background The biofilm‐inhibitory effects of electrolyzed saline (EOS) vary widely due to differences in formulations and treatment methods. This study analyzed the impact of EOS on key oral microbial species and used serial 3D‐intraoral scans to evaluate its effects on de novo biofilm formation.

Association between serum α‐Klotho levels and severity of periodontitis in a representative U.S. population

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis, a chronic inflammatory disease, is linked to systemic conditions such as cardiovascular and kidney disease. Serum α‐Klotho, an anti‐aging protein with anti‐inflammatory properties, has been associated with systemic diseases, but its role in periodontitis is unclear.

Immunomodulators, associated or not with systemic antibiotics, to treat periodontitis: A 1‐year multicenter, placebo‐controlled, double‐blind, randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Immunomodulatory agents such as omega‐3 (ω‐3) and low‐dose aspirin (ASA) have been proposed as effective adjuncts in the treatment of periodontitis. However, they still lack long‐term studies and head‐to‐head evaluation with metronidazole (MTZ) and amoxicillin (AMX), the adjunct protocol with the strongest scientific evidence of ...
