Background: Hyaluronic acid (HA) fillers are popular for the treatment of signs of facial skin aging.
Objective: The objective of this study was to confirm the performance and safety of a new cohesive polydensified matrix HA filler ([CPM-HA20G, Belotero Revive, lidocaine-free], Merz Pharmaceuticals GmbH, Frankfurt, Germany) for the treatment of early signs of facial skin aging by use of biophysical measurements as well as subject and investigator satisfaction.
Methods: Twenty-five healthy female subjects with signs of facial skin aging were enrolled in this open-label, rater-blinded, observational post-market clinical follow-up study, and received 20 micropuncture treatments of 50 µL CPM-HA20G each into the lower cheek area at three injection visits 4 weeks apart.

Objective: The limited availability of autogenous oral mucosa in oral and maxillofacial surgery for intraoral grafting after trauma or tumor resection can be balanced by the use of tissue-engineered oral mucosa. However, the use of tissue engineering in autologous grafts is still subject to further research. The aim of this study was to evaluate conditions that lead to a rapid proliferation of vital and highly proliferative oral keratinocytes, which can be used in tissue engineering and consequently help improve surgical management of intraoral mucosal defects.

No specific pathologic aspects or histological features are included in the most current definition. This study investigates characteristics of BRONJ with a special emphasis on histomorphologic aspects, evaluating the role of Actinomyces spp.

One key factor lies in the poor revascularization of simple onlay grafts. The the aim of this study was to evaluate the revascularization processes in autogenous bone grafts from the iliac crest to the alveolar ridge.

Material And Methods: Using a well-established sheep model autogenous bone grafts were harvested form the iliac bone. A combination of a Collagen Membrane (CM) and Deproteinized Bovine Bone Material (DBBM) was used to cover the bone graft (Experiment 2).
Background: Mid-dermal injection of stabilized hyaluronic acid (HA) is well established as a treatment to reduce the effects of skin aging.
Objective: To assess the efficacy and safety of a stabilized HA-based gel of non-animal origin manufactured using the patented NASHA® technology (Restylane® Vital Light, Q-Med AB, Uppsala, Sweden) administered using a pre-filled micropuncture injector device for rejuvenation of the skin.
Methods: Three treatment sessions 4 weeks apart were performed on one side of the face, the dorsum of one of the hands and one side of the décolletage, leaving the other side untreated.

Objectives: The lack of oral mucosa in oral and maxillofacial surgery for intraoral grafting after trauma or tumor resection can be balanced by tissue-engineered oral mucosa. The aim of this study was to generate a tissue-engineered oral mucosa equivalent (OME).
Study Design: First, primary oral fibroblasts were cultured for 7 days on different materials: Tissufoil E (TFE), dermal regeneration template (DRT), and Vicryl.
Background: Intradermal injection of hyaluronic acid (HA) is currently the criterion standard to reduce the appearance of nasolabial folds (NLF).
Objective: Effects of a monophasic HA filler using cohesive polydensified matrix (CPM) technology were compared with those of nonanimal stabilized HA (NASHA).
Materials And Methods: In a double-blind, half-side comparison, 20 subjects (ages 35-65, mean 52 ± 5.
Objectives: This study aims to evaluate the expression of various immunohistochemical growth factors and vascularization markers in augmentation on the mandible comparing onlay bone grafts and Guided Bone Regeneration (GBR).
Materials And Methods: Using a sheep in vivo model, autogenous bone grafts were harvested from the iliac crest. A combination of a resorbable collagen membrane (CM) and a Deproteinized Bovine Bone Material (DBBM) was performed.
Exposure of human oral mucosa to lead (Pb) and benzo[a]pyrene (BaP) by inhalation and ingestion can lead to pathological conditions via apoptosis and oxidative and nitrosative stress. However, few studies have investigated the effects of Pb and BaP on oral mucosa cells. Furthermore, previous studies focused on chronic Pb and BaP exposure.

Background: The increase in reported cases of osteonecrosis of the jaw has increased the clinical significance of bisphosphonate therapeutic agents in the dentistry field.
Methods: We present a rare and severe case of bisphosphonate-related osteonecrosis of the jaw caused by medicamentous treatment of complex regional pain syndrome. This article reviews the current international prevention and treatment guidelines with regard to bisphosphonate treatment.
Introduction: Mucormycosis of the head and neck is a rare disease increasingly occurring in immunocompromised patients. We report on two cases with different outcomes.
Case Reports: A 63-year-old female presented with a recently developed deformation of her right cheek and nose combined with a loosening of the teeth.
Background: Skin and hair appearance is important to body image. Oily skin and oily, impaired hair quality, which can develop in women taking certain types of hormonal contraceptives, may cause psychosocial stress.
Objectives: The aim of the current study was to investigate the effects of an oral monophasic contraceptive (0.
Background: Primary focal hyperhidrosis plantaris can cause impairment in social, physical, leisure and occupational activities. Topical treatment with aluminium chloride is the first-line treatment. The aim of this trial was to evaluate efficacy and safety of two different concentrations of aluminium chloride hexa-hydrate (12.

Most applied commercial materials are based on hydroxyapatite, which is not chemically degradable under physiological conditions. Here we report the effect of a long-term intramuscular implantation regime on the dissolution of various low temperature calcium and magnesium phosphate ceramics in vivo.

The aim of this study was to analyze the biologic reactions of the bone tissue adjacent to the pin to determine the relationship among the osseous anchorage of pins, the incidence of infections, and the histologic appearance.
Methods: Three groups of sheep received a tibial osteotomy stabilized by external fixators.

Synthetic bone replacement materials are of great interest because they offer certain advantages compared with organic bone grafts. Biodegradability and preoperative manufacturing of patient specific implants are further desirable features in various clinical situations. Both can be realised by 3D powder printing.

Background: Kimura's disease is a rare inflammatory disease that mainly affects Asians and most often occurs in the deep lymph nodes of the head and neck. We report on a rare case of Kimura's disease in the hard palate of a white man.

Brushite (CaHPO(4) x 2H(2)O)-forming calcium phosphate cements are of great interest as bone replacement materials because they are resorbable in physiological conditions. However, their short setting times and low mechanical strengths limit broad clinical application. In this study, we showed that a significant improvement of these properties of brushite cement could be achieved by the use of magnesium-substituted beta-tricalcium phosphate with the general formula Mg(x)Ca((3-x))((PO(4))(2) with 0 < x < 3 as cement reactants.
