Commercially available hyaluronic acid dermal fillers used as a scaffold in regenerative endodontic procedures (REPs) have demonstrated attractive potentials. This study aimed to histologically evaluate the outcome of REPs using Restylane Lyft (HA) as a scaffold. REPs were performed on pulpless, immature roots in dogs ( n = 69). The roots were divided into four groups: blood clot (BC), Restylane Lyft (BC + HA), negative control, and positive control. At 13 weeks postoperatively, hard tissue formation, vascularization, the presence of vascularized soft connective tissue and collagen fibers, the degree of inflammation within pulp spaces and/or periapical tissues, and apical closure were evaluated histologically...

BACKGROUND: The technology of manufacturing hyaluronic acid (HA) fillers is evolving to increase their safety and durability. This study aimed to compare the volume maintenance effect of stromal vascular fraction (SVF) on different types of HA fillers. METHODS: In this controlled experiment, HA fillers mixed with SVF were injected into the right upper back and HA fillers alone were injected into the left upper back of each mouse. A total of 35 mice were separated into five groups according to the type of commercially used HA filler: Juvederm Voluma XC, Restylane Lyft, Restylane Skinboosters Vital, Giselle Ligne Signature 2, and Giselle Ligne Universal...

SUMMARY: Hyaluronic acid fillers are widely used for the augmentation of facial soft tissues. Hyaluronic acid fillers can be monophasic or biphasic and have different characteristics, especially regarding volumetric effects and maintenance potential. However, there is paucity of long-term quantitative and objective data on clinical outcomes following hyaluronic acid injection. In this study, the authors evaluated volumetric changes over 2 years and the maintenance potentials of both types of fillers on the anteromedial cheek using objective three-dimensional measurements...

Scaffolds are crucial elements for dental pulp regeneration. Most of the currently used scaffolds in regenerative endodontic procedures (REPs) are unsuitable for chairside clinical use. This study aimed to evaluate the effect of an injectable synthetic scaffold (Restylane Lyft) on human bone marrow mesenchymal stem cell (hBMSC) viability, proliferation, and osteo/dentinogenic differentiation in a regenerative endodontic organotype model (REM). hBMSC were loaded in an REM either alone (hBMSC group) or mixed with the Restylane Lyft scaffold (Restylane/hBMSC group) and cultured in basal culture medium (n = 9/group)...

Objectives: To examine the degree of agreement between MRI and histologically generated volumetric measurements of residual injection laryngoplasty material. Methods: Following left recurrent laryngeal nerve transection, rabbit vocal cords were injected with jellyfish collagen, Cymetra®, or Restylane®. Laryngeal tissue was harvested 4 or 12 weeks post injection followed by MRI imaging and histologic cross-sectioning. Two raters estimated the volume of remaining injection material in specimens within MRI and histologic axial cross sections...

Restylane® Lidocaine is one of the most widely used hyaluronic acid (HA) fillers to replace lost or displaced volume during tear trough correction. Patient goals for tear trough correction include looking less tired or removing dark circles and this may be achieved by administering HA filler into the infraorbital region to correct the lower eyelid relative to the volume deficit, thereby smoothing the transition from the lower eyelid to the cheek. To achieve patient satisfaction and consistent results with Restylane, optimal application is essential; however, clinical guidance based on experience is limited...

BACKGROUND: Hyaluronic acid (HA) fillers have been studied extensively on the face; however, their safety and efficacy on the neck has not yet been evaluated in a prospective trial in the United States. OBJECTIVE: Analyze the efficacy and safety of a HA filler for static horizontal neck rhytides using either a cannula or needle. MATERIALS AND METHODS: Twenty-six subjects were randomized to receive up to 1 mL of the HA filler Restylane Refyne (HARR, n = 20) or saline (n = 6) using a cannula on one side and a needle on the other with optional repeat treatment...

BACKGROUND: Hyaluronic acid (HA) fillers are known to be effective for the correction of facial wrinkles and folds, but there is no clinical study that compares the efficacy of small-to-medium-particle HA fillers and large-particle HA fillers for the correction of nasolabial folds (NLFs). Moreover, injection depth also plays an important role in the correction of NLFs as well as improvement of facial aesthetics. OBJECTIVES: To assess the efficacy, safety, and durability of a small-to-medium-particle HA filler, Restylane, and a large-particle HA filler, Yishumei, as well as the effect of injection depth in the correction of moderate-to-severe NLFs and facial aesthetics in a Chinese population...

MATERIALS AND METHODS: Thirty-nine colobomatous eyelids in 24 feline patients with secondary keratitis were recruited to the study group. RESULTS: Keratitis and trichiasis were markedly resolved in 27/39 (69.2%) eyelids after a single procedure...

Nonsurgical cosmetic treatments have significantly increased over the last decade. Therefore, this study aims to review the features that should be considered in orofacial esthetic procedures, thorough of a proposal of a new concept called the tissue mimicry concept (MIMT concept) and filling techniques. The MIMT concept described in this article comprises knowledge about anatomy of the face and associated structures, understanding of aging and how this process affects the facial tissues interactions (skin, subcutaneous tissues, muscles, and bones), interpretation of facial analysis, comprehension of dermal fillers characteristics and discernment of the correct filling technique for each region...

Purpose: Hyaluronic acid (HA)-based dermal fillers have been approved for various clinical indications, both cosmetic and medical. Previous studies that have assessed the performance of HA dermal fillers have primarily focused on evaluating filler durability, and only a few have studied their distribution within the tissues. The present study aimed to compare tissue integration of various types of HA dermal fillers having different clinical indications and varying injection depths. Methods: To examine the local inflammatory response and distribution pattern of 14 HA dermal fillers (six Neuramis [NEU], one Belotero [BEL], three Juvéderm [JUV], and four Restylane [RES]), each product was injected intradermally and subcutaneously at the backs of two male miniature pigs...

There is significant variation in treatment parameters when treating the infraorbital region. Thorough knowledge of these pertinent factors, choice of the optimal filling material, and proper understanding of the anatomy of this unforgiving region will contribute to a safe, effective, and natural result. We aim to conduct a systematic review of published literature related to soft tissue fillers of the tear trough and infraorbital region. A search of published literature was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included PubMed, Embase, and Science Direct databases...

BACKGROUND: Adverse events due to hyaluronic acid fillers (HAFs) may be treated with hyaluronidase, an enzyme that cleaves bonds within hyaluronic acid. This study reviews the efficacy of currently available hyaluronidase preparations in breaking down commercial, cross-linked HAFs. METHODS: Three HAFs were used in this study (Restylane, Juvederm Voluma, and Belotero [BEL] Balance). A laser-based particle size analyzer (Malvern Mastersizer 3000) was used to calculate particle sizes in untreated HAFs (controls) and those treated with 450 units of hyaluronidase (Hylenex) for 5 and 30 minutes...

PURPOSE: At present, there is a paucity of data regarding the thrombogenicity of hyaluronic acid fillers (HAFs). This article quantitatively analyses the thrombogenicity of 2 commonly used HAFs: Restylane Lyft and Juvéderm Ultra. METHODS: Thrombogenicity was assessed using the Thrombodynamics Analyzer System and plasma obtained from healthy controls. Following the addition of HAFs or control, spontaneous clot formation time, initial rate of clot growth, average rate of clot growth over 30 minutes, and clot size at 30 minutes was measured for each sample...

BACKGROUND: Hyaluronic acid (HA) fillers have been widely used in humans since 1958 because of their biomedical safety. Restylane® was introduced in the1990s as a favorable temporary filler option for facial augmentation. Subsequently, many new HA filler products, including the Sardenyashape® , have been introduced, but comparative studies of these products are limited. Here, we compared tolerability (wrinkle severity rating scale, WSRS), pain (visual analog scale, VAS score), satisfaction (global esthetic improvement scale, GAIS), and safety of a new monophasic HA (MHA) filler (Sardenyashape® ) containing lidocaine, used to correct nasolabial folds (NLFs), with those of biphasic HA (BHA) filler (Restylane LYFT® ) containing lidocaine...
