This study aimed to compare the perceptions of smile esthetics among general practitioners, periodontists, and laypeople. Photographs of smiles were taken and digitally modified to create different gingival conditions: gingival asymmetry, unilateral gingival recession, and bilateral gingival recession. These photographs were evaluated by 150 volunteers (19-70 years old) using a 100.0-mm visual analog scale. The volunteers consisted of 50 laypeople with no knowledge of dentistry, 50 general dentists, and 50 periodontists...

A comprehensive knowledge of the optical properties of composite resins is essential to achieving optimal results in direct anterior restorations. This case report describes an anterior composite resin restoration fabricated with a layering technique and explains how to use a simple photographic method to verify that the desired optical effects are reproduced. A Class IV restoration was completed on a maxillary central incisor with the help of a silicone guide. An esthetic result was achieved through careful color examination as well as material selections that were based on knowledge of the translucency, opacity, and fluorescence of the chosen direct composite resins...

Introduction: Chronic paronychia (CP) is an inflammatory disease of the nail folds. Staging of CP is important for clinicians. We developed an objective scale that evaluates each finding of CP separately in addition to evaluating the treatment process and follow-up. Methods: A new "chronic paronychia severity index scale" was developed to enable dermatologists to examine all features of CP. A previous categorical severity scale and this new scale were used for the evaluation of CP by 6 different dermatologists...

For innumerous reasons, ultrasound (US) imaging is becoming more and more popular in musculoskeletal medicine. Herewith, since this imaging technique is user dependent, prompt and sufficient training is crucial for its better clinical utility. In this regard, with this paper, we aimed to focus on common artifacts that are observed in routine US scanning during daily musculoskeletal practice. Yet, those imaging findings need to be well recognized in order not to be misinterpreted. Likewise, we have illustrated and discussed those artifacts in similarity with particular natural photographs...

Modern interpretation of head conformation in the Cavalier King Charles spaniel (CKCS) has favoured a smaller, more exaggerated, brachycephalic type than originally described in the 1929 breed standard. Recent research studies identified brachycephaly and reduced hind cranium as two conformational (dysmorphic) features that increase risk for symptomatic Chiari-like malformation and secondary syringomyelia (SM). A prospective pilot study investigated the hypothesis that dysmorphic head features could be assessed visually and correlated with risk of SM...

This article represents the results of testing the surface condition of shafts manufactured by the burnishing process. The shafts with a hardness of approximately 62 HRC (Rockwell C). were burnished with a ceramic ball (Si₃N₄), where the force range was controlled by the means of a hydraulic system. The machining process consisted of hard turning shafts with cubic boron nitride (CBN) inserts, followed by burnishing with the use of various machining parameters, such as feed and force. The research focused on the examination of burnished surfaces, which was conducted for various structures after hard turning, and with variable burnishing parameters...

Xiaoli Kang, Chunhong Li, Zhou Zheng, Xudong Cui
Developing energetic composite materials consisting of fuel and oxidizer is an effective strategy to enhance the energy release property. However, this strategy has rarely been applied in Potassium Perchlorate (KClO₄)-containing energetic materials, even though KClO₄ is a much stronger oxidizer than most previously reported metal-oxide oxidizer. One of the main obstacles is the lack of simple and in situ ways to introduce KClO₄ into the composite. In present work, micrometer KClO₄/Zirconium (KClO₄/Zr) composite particles were successfully prepared using a facile chemical solution-deposition method...

BACKGROUND: Hair and scalp involvement in systemic lupus erythematosus (SLE) can manifest as scarring alopecia, non-scarring alopecia or scalp/hair shaft changes without apparent hair loss. While trichoscopic signs in chronic cutaneous lupus are well estabished, data on SLE patients with normal-looking or non-scarring scalp are limited. OBJECTIVES: To investigate trichoscopic features of SLE patients without chronic cutaneous scalp lesions and compare the findings with normal controls, as well as determine which feature associates with systemic disease...

This paper explores some of the challenges of publishing photographs generated as part of sexuality research. It aims to initiate discussion of these issues to enable sexuality researchers to consider and navigate the use of images in their work. Examples highlighting these difficulties are employed from a photo-method project which examined young people, sexuality and schooling. It is argued that existing child-sex-panics rendered these images risky and intensified their scrutiny by gatekeeping forces. The discussion contributes to a broader conversation within the field of sexualities about the constitution of sexuality research as dirty work...
