Long‐term stability of conventional non‐regenerative periodontal treatment for furcation defects

Periodontology 2000, EarlyView.
Abstract Background Furcation involvement (FI) in multi‐rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities.

Regenerative periodontal surgery and orthodontic therapy in the treatment of patients with stage IV periodontitis and pathologic tooth migration

Periodontology 2000, EarlyView.
Abstract Background Patients suffering from stage IV periodontitis are often characterized by pathologic tooth migration, drifting, flaring, posterior bite collapse, and secondary occlusal trauma (case type 2). Many times, these patients seek treatment because of functional and esthetic demands.

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Long‐term stability of periodontal plastic surgery featuring traditional autogenous graft and coronally advanced flap alone

Periodontology 2000, EarlyView.
Abstract Background Coronally advanced flap (CAF), either alone or in combination with a connective tissue graft (CTG), represents one of the most extensively investigated surgical approaches for the treatment of gingival recessions, demonstrating high rates of mean root coverage (MRC) and complete root coverage (CRC). However, evidence regarding their

Framing the Square: Cinematic Procedures and Visual Regimes in Diamela Eltit's Lumpérica

Bulletin of Latin American Research, Volume 45, Issue 4, October 2026.
ABSTRACT This article examines how Diamela Eltit's Lumpérica (1983) constructs a regime of visibility through the spatial organisation of the public square that structures the novel. While criticism has often emphasised the text's linguistic fragmentation and performative dimensions, less attention has been paid to the visual procedures through which ...

Distinct Microbiota and Functional Pathway Profiles Define Success and Failure in Regenerative Endodontic Treatment

International Endodontic Journal, Volume 59, Issue 10, Page 2223-2237, October 2026.
ABSTRACT Aim To characterize the intracanal microbiota and identify key microbial taxa and functional pathways associated with regenerative endodontic treatment (RET) outcomes. Methodology In this observational cohort study, 196 samples were collected at five time points from external tooth surfaces (T1, T4) and root canals (T2, T3, T5).
