Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Volumetric analysis of root coverage with porcine acellular dermal matrix: Case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Gingival recession is prevalent and often treated with coronally advanced flap plus connective tissue graft (CAF+CTG). Porcine acellular dermal matrix (PADM) offers a donor‐site‐free alternative. Contemporary digital imaging allows minimally invasive, three‐dimensional (3D) soft‐tissue assessment. This case report quantified 3D soft‐

Evaluation of polymerization shrinkage stress and cuspal strain in natural and typodont teeth [PDF]

Brazilian Oral Research
To evaluate the polymerization shrinkage stress and cuspal strain (CS) generated in an artificial (typodont) and in a natural tooth using different resin composites. Twenty artificial and 20 extracted natural molars were selected. Each tooth was prepared

Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

Clinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

A case series of necrotizing periodontal diseases in hospitalized patients: What hasn't been said yet?

Clinical Advances in Periodontics, EarlyView.
Abstract Background Necrotizing periodontal diseases (NPDs) are uncommon and severe inflammatory conditions characterized by tissue necrosis, painful ulceration, and rapid clinical progression, frequently associated with systemic immunosuppression. Limited data exist regarding their clinical presentation and management in hospital settings.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.
