Enamel microabrasion has become accepted as a conservative, nonrestorative method of removing intrinsic and superficial dysmineralization defects from dental fluorosis, restoring esthetics with minimal loss of enamel. However, it can be difficult to determine if restoration is necessary in dental fluorosis, because the lesion depth is often not easily recognized. This case report presents a method for analysis of enamel hypoplasia that uses quantitative light-induced fluorescence (QLF) followed by a combination of enamel microabrasion with carbamide peroxide home bleaching. We describe the utility of QLF when selecting a conservative treatment plan and confirming treatment efficacy. In this case, the treatment plan was based on QLF analysis, and the selected combination treatment of microabrasion and bleaching had good results.

Porcelain is considered to be one of the materials of choice for restoration where esthetics is of concern. But porcelain surface without final glazing treatment may induce undesirable results such as inflammatory respones on adjacent soft tissues due to plaque accumulation and increased wear of opposing teeth. Therefore, rough porcelain surface must be smoothened by final glazing treatment or chairside polishing procedure. The purpose of this study was to compare the surface roughness among self-glazed, overglazed and polished porcelain with various polishing kit, and to detect which phase of polishing is optimal in clinic. Specimens were fabricated with Vita VMK porcelain. The surface treatment of each group was performed as follows. Group 1 : overglazing treatment Group 2 : self-glazing treatment Group 3 : polishing with the Truluster Polishing System for Porcelain(Brasseler, U.S.A.) Group 4 : polishing with the Exa Cerapol Adjustment kit (Edenta dental products, Switzerland) followed by finishing with diamond-filled polishing paste Group 5 : polishing with the Shofu Porcelain Adjustment kit (Shofu inc., Japan) followed by finishing with diamond-filled polishing paste. At each polishing steps, the measurement of Ra and Rq values were performed, and the surface was examined by scanning electron microscope. The results were as follows: 1. Overglazing treatment brought smoother surface than self-glazing treatment. 2. Polishing systems without porcelain polishing paste did not make better result than self-glazing treatment. 3. Polishing system with porcelain polishing paste made similar result to overglazing treatment. 4. Applying diamond-filled polishing paste after using polishing system which has porcelain polishing paste produced surface as smooth as overglazing treatment does.

ABSTRACT This study aimed to determine the influence of dental aesthetics in finding a job as a dentist and the employer’s willingness to interact in personal and professional setting. Ten dental students’ smiling photographs were taken prior to the correction of their dental aesthetic problems. The images were digitally altered to an ideal smile. Two different questionnaires were prepared (Groups A and B) with the images with or without alteration (ideal and non-ideal smile). The images with an ideal smile and non-ideal smile were randomly allocated in each group and assessed by 84 private dental practitioners who has the authority of hiring another dentist in their practice. Four questions were asked on the likelihood of being hired, friendliness, intelligence, and good clinical skills. In general, the students with ideal smile were more likely to be hired (p < 0.05) except for those presented with buccally erupted canine and mild median diastema. Students with ideal smile scored higher in terms of friendliness and intelligence than the non-ideal smile. Most of them did not correlate a smile to an individual’s clinical skills and manual dexterity (p > 0.05). In conclusion, individuals with an ideal smile was graded more friendly and intelligent thus increases the employer’s willingness to interact personally and is more likely to be hired in contrast to a person with a non-ideal smile. Therefore, an aesthetically pleasing smile is one of the factors affecting the chances of a dentist to be hired and improve their personal interaction with people.

Exposure of gingival margin is frequently observed in anterior teeth aesthetic restoration. How to obtain an expected result is a significant challenge during prosthodontic treatment. The present article discussed gingival biotype, conditions of periodontal tissue, location of margin of restoration, gingival retraction, and provisional restoration, etc, which would affect the final aesthetic outcome of anterior teeth restorations. The aim of this article is to figure out how to effectively avoid the exposure of gingival margin in anterior teeth aesthetic restoration, and to improve the finally aesthetic outcome of anterior teeth restoration.

OBJECTIVE: To explore the possibility of the Smile Lite MDP (Smile Lite Mobile Dental Photograph) portable dental photography system applying in anterior teeth aesthetic photography, and to provide the chance to simplify aesthetic photography process and facilitate communication among patients, dentists and dental technitians. METHODS: The Smile Lite MDP photography system combined with the smartphone were used to photograph the front occlusal phase photos of anterior teeth. The photographic conditions including the color temperature parameter, the Smile Lite MDP light position and the intensity settings were explored. The best photographic conditions were chosen by blind evaluation within experienced dentists and technicians through the method of the visual analogue scale/score (VAS) evaluation, which went through statistical analysis to figure out the optimum photograghic conditions. Smile Lite MDP photography system was used to photograph the front occlusal phase photos of anterior teeth under the optimum parameter by different magnifications. The width/height ratio of the central incisor and the front width ratio of the upper anterior teeth in those photos were measured and calculated respectively. The accuracy of the anterior teeth photos taken by Smile Lite MDP photography system was analyzed based on the photographs taken by digital single lens reflex (DSLR) camera. RESULTS: The optimum color temperature parameter of Smile Lite MDP portable camera system was 5 000 K, the optimum magnification was 4 times, the best light position was the side lights of Smile Lite MDP, the optimum intensity of lights was 2 grades. Photos taken by the optimum parameters won the highest score during the VAS evaluation and the result of statistical analysis had significant difference compared with other groups (P<0.05). When comparing the photos of the upper anterior teeth taken by the Smile Lite MDP portable photography system using 4 times magnification or by DSLR using the standard parameters, there was no significant difference neither in the width/hieght ratio of the central incisor nor in the front width ratio of the upper anterior teeth (P>0.05). CONCLUSION The Smile Lite MDP portable dental photography system applying in anterior teeth aesthetic analysis photography was capable to show the color and shape of anterior teeth in an accurate way by using the right photography parameters. Therefore, Smile Lite MDP portable dental photography system was considered to be a simple and easy photographic tool in clinical work.

A new clinic conception, healthy cosmetic management (HCM), was innovated introduced into diagnose and treatment of patients with high caries risk. The priority of HCM should be given to aesthetic restoration of teeth, taking consideration of the conserving of tissue and pulp of teeth and the balance between health and aesthetics, which may reach to the goal of the individual clinic treatment. HCM includes five steps: 1) caries risk assessment; 2) detection of initial caries; 3) digital aesthetic design; 4) minimally invasive therapy; 5) behavior management of caries and doctor-patient communication pattern. In this article, HCM is introduced into two aspects: process management and clinical protocols, followed by the combination of the clinical practice.

The minimal tooth reduction, esthetic appeal and biocompatibility of porcelain laminate veneers have made them one of the mainstream technologies for minimal invasive esthetic dental restorations. Cementation is a crucial step in ensuring retention, marginal seal and influencing the clinical longevity of veneer restorations. Experts from Society of Prosthodontics, Chinese Stomatological Association formulated operational specifications for the cementation of porcelain laminate veneers, so as to standardize the clinical operating procedures, achieve the long-term success of veneer restorations, and promote the application of porcelain laminate veneers.
