Disease severity, debridement approach and timing of drug modify outcomes of adjunctive azithromycin in non-surgical management of chronic periodontitis: a multivariate meta-analysis.

Background: Past meta-analyses have shown adjunctive systemic Azithromycin (AZI) to provide minor clinical benefits in scaling and root surface debridement (S/RSD). However, these have not considered the covariance of key outcome parameters; probing pocket depth (PPD) and Clinical Attachment Level (CAL) or systematically examined some potential sources of heterogeneity.

Aim: To jointly synthesize 6-month outcomes of systemic AZI as adjunctive to S/RSD in chronic periodontitis and investigate 3 potential sources of heterogeneity.

EphrinB2 signalling modulates the neural differentiation of human dental pulp stem cells.

Dental pulp stem cells (DPSCs) originate from the embryonic neural crest and have neurogenic potential. The present study investigated the roles of the forward and reverse EphrinB2 signalling pathways during DPSC neurogenesis. Treatment of DPSCs with recombinant EphrinB2-Fc protein over 7 days in a neural induction culture resulted in significant downregulation of the following neural markers: βIII-Tubulin, neural cell adhesion molecule (NCAM), nestin, neurogenin 2 (NGN2), neurofilament medium polypeptide and Musashi1.

Lapine periodontal ligament stem cells for musculoskeletal research in preclinical animal trials.

Background: Human periodontal ligament stem cells (hPDLSCs) have been shown to be a reliable source of mesenchymal stem cells (MSCs). On the other hand, rabbits have been commonly used in preclinical trials for musculoskeletal research. However, there is a lack of sufficient data on using rabbit periodontal ligament stem cells (rPDLSCs) for regenerative dentistry.

Oral Rehabilitation of Young Adult with Amelogenesis Imperfecta.

Background: Amelogenesis imperfecta is a heterogeneous group of hereditary disorders that affect the enamel formation of the primary and permanent dentitions while the remaining tooth structure is normal. Appropriate patient care is necessary to prevent adverse effects on dental oral health, dental disfigurement, and psychological well-being.

Aim: This clinical report presents a 27-year-old Chinese male with amelogenesis imperfecta (AI) and his restorative management.

Bilateral Condylar Hyperplasia-Nonsurgical Management: A Clinical Report.

Patients present with malocclusions in the form of bilateral open bite with functional and esthetic challenges. These are particularly so whereby these are acquired through growth anomalies that create a change in the occlusal status whereby a patient has to adapt to the challenge of the occlusal change. While surgical intervention is a considered option to correct such changes, not all patients are willing to endure the consequences of this intervention and as such this report presents a conservative minimally invasive approach.

Insect Analogue to the Lotus Leaf: A Planthopper Wing Membrane Incorporating a Low-Adhesion, Nonwetting, Superhydrophobic, Bactericidal, and Biocompatible Surface.

Nature has produced many intriguing and spectacular surfaces at the micro- and nanoscales. These small surface decorations act for a singular or, in most cases, a range of functions. The minute landscape found on the lotus leaf is one such example, displaying antiwetting behavior and low adhesion with foreign particulate matter.

The evaluation of prepared microgroove pattern by femtosecond laser on alumina-zirconia nano-composite for endosseous dental implant application.

Ceramic dental materials, especially alumina (20 %vol)-yttrium stabilized tetragonal zirconia poly crystal (A-Y-TZP20), have been considered as alternatives to metals for endosseous dental implant application. For increasing the bone-to-implant contact as well as the speed of bone formation, a new surface modification can be effective. The aim of this study was to design microgroove patterns by femtosecond laser on A-Y-TZP20 nano-composite disks for endosseous dental implant application.

A gecko skin micro/nano structure - A low adhesion, superhydrophobic, anti-wetting, self-cleaning, biocompatible, antibacterial surface.

Geckos, and specifically their feet, have attracted significant attention in recent times with the focus centred around their remarkable adhesional properties. Little attention however has been dedicated to the other remaining regions of the lizard body. In this paper we present preliminary investigations into a number of notable interfacial properties of the gecko skin focusing on solid and aqueous interactions.

High resolution time-intensity recording with synchronized solution delivery system for the human dynamic taste perception.

Background: Time-intensity sensory evaluation of human taste perception is useful to know the feedback of a taste stimulus from tongue. However, it has not been profiled together with reaction time under the constant stimulating tongue in high time resolution.

New Method: We first made intra-oral device to deliver taste solution to anterior, lateral and posterior tongue in standardized condition.

In vivo osteoprotegerin gene therapy preventing bone loss induced by periodontitis.

Objective: The objective of this study was to investigate the effects of osteoprotegerin (OPG) gene therapy on alveolar bone resorption caused by experimental periodontitis in rats, thus forming a foundation for potential clinical applications of OPG gene therapy in the treatment of periodontitis and peri-implantitis.

Material And Methods: To study the effects of OPG on alveolar bone protection, an experimental periodontitis model was used by placing a bacterial plaque retentive silk ligature in the gingival sulcus around the maxillary second molar tooth, injection of Porphyromonas gingivalis and high carbohydrate diet. A total of 30 Sprague-Dawley rats were randomly divided into three groups, with 10 rats in each group: group I (control) was treated with 10 μL normal saline injection; group II with 10 μL mock vector; and group III with 10 μL local OPG gene transfer by transfection with in vitro constructed pcDNA3.

Oral complications and management strategies for patients undergoing cancer therapy.

With cancer survival rate climbing up over the past three decades, quality of life for cancer patients has become an issue of major concern. Oral health plays an important part in one's overall quality of life. However, oral health status can be severely hampered by side effects of cancer therapies including surgery, chemotherapy, radiotherapy, and hematopoietic stem cell transplantation.

The fatigue bond strength of fixed-fixed versus cantilever resin-bonded partial fixed dental prostheses.

Statement Of Problem: Restorations using posterior resin-bonded partial fixed dental prostheses to replace missing premolar teeth were previously considered to have only variable success. Although 2-unit cantilevered resin-bonded partial fixed dental prostheses have been shown to have similar or improved clinical retention to their 3-unit counterparts, no in vitro evidence supports their use in preference to fixed-fixed designs.

Purpose: The purpose of this in vitro study was to fatigue load 2 different resin-bonded partial fixed dental prosthesis designs (3-unit fixed-fixed and 2-unit cantilevered) and then compare their bond strengths after loading to failure.
