A narrative review of papilla preservation techniques in clinical dentistry.

The interdental papilla is closely associated with oral health and dental aesthetics. Interproximal papilla is an essential component of pink aesthetics as well as an indispensable prerequisite for the health of oral tissues. The loss of papillary height not only considerably affects final esthetic results, but also brings a series of periodontal complications.

Multiprotein Adsorption from Human Serum at Gold and Oxidized Iron Surfaces Studied by Atomic Force Microscopy and Polarization-Modulation Infrared Reflection Absorption Spectroscopy.

Multiprotein adsorption from complex body fluids represents a highly important and complicated phenomenon in medicine. In this work, multiprotein adsorption from diluted human serum at gold and oxidized iron surfaces is investigated at different serum concentrations and pH values. Adsorption-induced changes in surface topography and the total amount of adsorbed proteins are quantified by atomic force microscopy (AFM) and polarization-modulation infrared reflection absorption spectroscopy (PM-IRRAS), respectively.

[Comparative study on the effect of microscopic revascularization and apexification in the treatment of pulp necrosis of permanent teeth].

Purpose: To compare the curative effect of microscopic revascularization and apexification in the treatment of pulp necrosis of permanent teeth.

Methods: Seventy-five cases of pulp necrosis in young permanent teeth were divided into two groups according to different treatment methods. Group A (n=30) underwent revascularization under microscope, while group B (n=45) underwent apexification.

Role of ubiquitin-specific protease 5 in the inflammatory response of chronic periodontitis.

Background: The systemic inflammatory response caused by chronic periodontitis is a risk factor for multiple diseases. Ubiquitin-specific protease 5 (USP5) is a kind of deubiquitinase which mainly responsible for dissociating unanchored polyubiquitin. However, the functions of USP5 in chronic periodontitis have not been reported.

Cullin3 aggravates the inflammatory response of periodontal ligament stem cells via regulation of SHH signaling and Nrf2.

It is found that the activation of Sonic Hedgehog (SHH) signaling pathway is related to the degree of inflammation in patients suffering from periodontitis. Cullin3 (CUL3), an important ubiquitin ligase, can control SHH signaling. In this study, we were dedicated to clarify the roles of SHH and CUL3 in -LPS (Pg-LPS)-treated periodontal ligament stem cells (PDLSCs).

Effects of Quartz Splint Woven fiber periodontal fixtures on evaluating masticatory efficiency and efficacy.

Masticatory efficiency is altered by mobile teeth resulting from periodontal disease. The goal of our study was to investigate changes before and after fixation of mobile teeth with a Quartz Splint Woven high-strength quartz fiber splint and evaluate the fixation effect.Forty-two patients with chronic severe periodontal disease and 2 to 3 degree tooth mobility underwent fixation with Quartz Splint Woven quartz fiber splints.
