A MODERN VIEW ON THE TREATMENT OF CLASS IV RECESSION ACCORDING TO MILLER.

Introduction: Interproximal attachment has received much attention in modern periodontology because it is a key diagnostic and prognostic factor. Currently, we can find many articles with results of bare root coverage, but few data and studies that describe root closure and obtaining interproximal attachment at the same time.

Objectives: The purpose of this study is to introduce a double-layer tunnel surgical technique for gingival papilla reconstruction and regeneration of the supraalveolar interproximal attachment.

PROSPECTS AND LONG-TERM RESULTS AFTER ENDODONTIC SURGERY.

Aim: to analyze the current literature data on the topic of prospects and distant results after endodontic surgery.

Material And Methods: A systematic review was conducted following the PRISMA 2020 guidelines. This review was written with the help of literature searches in the electronic databases Google Scholar and PubMed.

Revealing Long-Range Order in Brush-like Graft Copolymers Through In Situ Measurements of X-Ray Scattering During Deformation.

Brush-like graft copolymers (A-g-B), in which linear A-blocks are randomly grafted onto the backbone of a brush-like B-block, exhibit intense strain-stiffening and high mechanical strength on par with load-bearing biological tissues such as skin and blood vessels. To elucidate molecular mechanisms underlying this tissue-mimetic behavior, in situ synchrotron X-ray scattering was measured during uniaxial stretching of bottlebrush- and comb-like graft copolymers with varying densities of poly(dimethyl siloxane) and poly(isobutylene) side chains. In an undeformed state, these copolymers revealed a single interference peak corresponding to the average spacing between the domains of linear A-blocks arranged in a disordered, liquid-like configuration.

Enhancing the Biomimetic Mechanics of Bottlebrush Graft-Copolymers through Selective Solvent Annealing.

Self-assembled networks of bottlebrush copolymers are promising materials for biomedical applications due to a unique combination of ultra-softness and strain-adaptive stiffening, characteristic of soft biological tissues. Transitioning from ABA linear-brush-linear triblock copolymers to A-g-B bottlebrush graft copolymer architectures allows significant increasing the mechanical strength of thermoplastic elastomers. Using real-time synchrotron small-angle X-ray scattering, it is shown that annealing of A-g-B elastomers in a selective solvent for the linear A blocks allows for substantial network reconfiguration, resulting in an increase of both the A domain size and the distance between the domains.

Irrigation in Endodontics: Polyhexanide Is a Promising Antibacterial Polymer in Root Canal Treatment.

Background: chronic apical periodontitis is a common pathology in dentistry, especially in endodontics. It is necessary to systematize data concerning commonly used irrigation solutions. The development of new protocols for endodontic treatment is a very promising direction.
