Color Ranges and Distribution of Human Teeth: A Prospective Clinical Study.

This study investigated the in vivo color range of human teeth using a research-grade noncontact spectroradiometer, analyzing the effects of gender, age, ethnicity, and lifestyle factors, including diet, smoking, and oral hygiene. A total of 1004 participants were recruited at two research sites and stratified by gender, age, and ethnicity, and data on their dietary and oral habits were collected. Noninvasive color measurements of an upper central incisor were performed using a spectroradiometer and a fiber-coupled Xe-Arc light source. Color differences were computed using the CIELAB and CIEDE2000 color difference formulas, statistically analyzed, and interpreted through comparisons with 50:50% perceptibility (PT) and acceptability (AT) thresholds for dentistry. CIELAB and CIEDE2000 color coordinate values varied significantly. Female teeth appeared lighter and less yellow than men's. Age correlated with darker, more chromatic teeth, stabilizing only after Age 46. Significant ethnic differences were observed, particularly between African-American and Asian participants. Coffee consumption impacted teeth yellowness and chromaticity, while tea had no significant effect. Frequent tooth brushing led to lighter teeth, and tooth whitening considerably influenced color, emphasizing the effect of cosmetic dental treatments. Smoking showed minimal impact, with slight discoloration noted among light smokers compared to nonsmokers. Color coordinate values by gender, age, and ethnicity exhibited statistically significant differences and, in most cases, noticeable color differences. With exceptions, the dietary/oral habits of the patient had a significant impact on the color of human teeth. The findings from this study provide detailed information and understanding of the color range and distribution of human teeth, which can help enhance the esthetic outcome of dental care and, consequently, the patient's satisfaction.

Influence of dental midline deviation with respect to facial flow line on smile esthetics-A cross-sectional study.

A contemporary concept states that dental midline deviation towards the direction of facial flow line (FFL) can mask the compromised smile esthetics. This study aimed to identify a range of midline deviations that can be perceived towards or away from the FFL influencing smile esthetics. A cross-sectional study was conducted using a frontal smile photograph of an adult female. The photograph was altered on Adobe Photoshop software into six different photographs by deviating the dental midlines towards and away from the FFL. A constant deviation of chin towards the left side was incorporated in all the photographs. Forty-three laypersons (LP) and dental professionals (DPs) evaluated those photographs. Independent t-test was used to compare the perception of dental midline deviation between LP and DPs. Simple linear regression was run to identify the factors associated with the scoring. A statistically significant difference was observed for picture two with 4 mm towards FFL in the perception of midline deviation between LP and DPs. LP could not perceive the midline deviations up to 4 mm while DPs were able to perceive deviations above 2 mm. The greater the age the better the scores were and female raters had a greater inclination towards poor scores. From 2 to 4 mm of midline deviation towards the FFL can be tolerated by LP and DPs. These findings underscore the importance of considering facial symmetry in orthodontic and cosmetic dental treatments to optimize smile esthetics.

Triple digital guides for implant-supported restorations with alveoloplasty procedure in the esthetic zone.

The principal aim of this report is to address the challenge of integrating prosthetic crowns with natural dentition in the esthetic zone. It highlights the utilization of a prosthetically driven treatment plan, designed to ensure predictable esthetic outcomes. This report details a technique that utilizes three digital guides, all derived from a 3-dimensional digital smile design. The integration of a restoration guide, an implant drilling guide, and an alveoloplasty guide is described. These tools collectively facilitate the precise execution of both surgical and prosthetic procedures, enhancing treatment accuracy and esthetic integration. This technique considers the esthetic prosthetic crowns, implant positions, and alveoloplasty collectively. It enhances the predictability of esthetic outcomes in oral implantology and potentially provides an integrated prosthetically driven workflow in cosmetic dental treatments. The application of multiple digital guides derived from the same prosthetically driven treatment significantly enhances the predictability of esthetic outcomes in oral implantology.

Description of the concern for dental aesthetics in dental students from UNIANDES, Ecuador

Oral diseases have a significant impact on aesthetics and well-being, particularly affecting adolescents. This developmental phase is marked by noticeable physical and psychological changes, where self-image and social perception become crucial and can adversely influence self-esteem. The study conducted in May 2023 at UNIANDES University, Ecuador, aimed to describe the oral health of dental students, analyzing how dental aesthetics affects perfectionism and self-worth. Classified as descriptive, observational, prospective, and cross-sectional, detailed questionnaires were administered to first-, fifth, and sixth-semester students, providing in-depth insight into the interaction of these factors in a university setting. The study found that concern for dental aesthetics increases with academic progression. Students in advanced semesters show a growing concern for the appearance of their teeth and are more willing to seek cosmetic dental treatments. This attitude is accompanied by a more frequent comparison with the teeth of others and an awareness of the social impact of their dental aesthetics. Such findings highlight a direct correlation between the level of study and dental self-perception, emphasizing the need to include psychosocial support in dental training. It is concluded that progress in the dentistry career entails a greater self-criticism of dental aesthetics, highlighting the importance of educational strategies to manage expectations and promote mental health

A Cross-Sectional Online Survey on Knowledge, Awareness, and Perceptions of Hollywood Smile Among the Saudi Arabia Population

Background: Hollywood smile has gained popularity in recent times to improve aesthetics among the general population. Since patients’ perceptions of dental aesthetics play a vital role in planning and evaluating cosmetic dental treatment, it is essential to understand their knowledge, awareness, and factors that influence their perceptions of dental aesthetics. Objectives: The objective of this study was to assess the knowledge, awareness, and perceptions of Hollywood smile among the general population in Saudi Arabia. Methods: A close-ended questionnaire consisting of demographic information and 20 questions related to Hollywood smile was circulated through social media in Saudi Arabia. Statistical analyses of the data obtained were performed using Statistical Package for Social Sciences software (SPSS version 17, USA). Frequencies, percentages, and mean and standard deviation were calculated using descriptive statistics. Pearson chi-squared test was employed to test the association between the demographic variables, such as age, gender, and education levels, with the questionnaire items. Results: A total of 4104 participants responded to the study questionnaire. The responses to the questionnaire revealed that nearly half of the participants were not satisfied with their dental appearance (48.6%). The majority of the participants had heard or known about Hollywood smile (98%). About 42% of study participants were aware of the complications involved in the procedure. The results revealed that the younger generation (18 to 30 years) had more awareness and felt more need for dental aesthetics (p=0.001). The proportion of male participants who underwent Hollywood smile correction were more than females (p=0.001). Graduates showed more awareness regarding smile, dental aesthetics, and Hollywood smile than the other categories (p=0.001). Conclusion: This study has shown that the younger generation, female participants, and graduates had more awareness regarding smile, dental aesthetics, and Hollywood smile.

Comparative analysis of smile esthetics between top celebrity smile and a Southern European population

Statement of problemThe analysis of different parameters involved in the esthetic perception of the smile is important for the correct planning of cosmetic dental treatments. PurposeThe purpose of this study was to analyze the differences in the main parameters of smile esthetics among celebrities identified as having the best esthetic smiles and a young Southern European population. Material and methodsThe study consisted of a control group of 144 dental students from the University of Seville (69.4% women; 30.6% men) with a mean ±standard deviation age of 23.19 ±0.5 years and photographs of 58 celebrities identified as having the best esthetic smiles (74.1% women; 25.9% men) with a mean ±standard deviation age of 42.09 ±2.25 years. Photographs of the celebrities were obtained from the Internet, and standardized photographs were made of the control group. The variables measured were smile line, smile arc, incisal edges and lower lip relationship, smile width, dental midline deviation and tilting, buccal corridor widths, and angulation discrepancy between interpupillary line and commissural line and between interpupillary line and occlusal plane. The data obtained were processed in a statistical software program for a descriptive statistical analysis and for inferential analysis parametric statistical tests by applying the Wilcoxon, chi-square, Student t, and kappa index tests (α=.05). ResultsStatistically significant differences (P<.01) were found between the groups in terms of smile width, smile arc, midline deviation and tilting, and angulation discrepancy between the interpupillary line and the commissural line. Smile arc was the only variable found to be different (P<.01) in relation to sex. ConclusionsCharacteristics of the most esthetic smiles were no deviation or tilting of the maxillary midline, showing a greater number of teeth in the smile, displaying incisal edges parallel to the lower lip (particularly in women), and displaying occlusal and commissural planes parallel to the interpupillary line.

The true cost of dental implant tourism: A case report

Many patients travel abroad seeking cosmetic dental treatment, in particular dental implants. However, there are hundreds of dental implant systems being used globally by dentists of all training backgrounds. Furthermore, complications can occur that patients may expect their general dental practitioner in the UK to be able to manage. The following report describes the case of a 71-year-old, medically compromised patient who presented with complaints consistent with the immediate failure of dental implants that happened to be placed abroad. On closer examination, the dental implants themselves were highly questionable in their design and placement. An incidental finding was also made in the maxillary sinus. CPD/Clinical Relevance: To acknowledge that implant dentistry is increasing in popularity as patients have the freedom to access dental implant treatment globally. UK dentists are expected to manage these dental implants on the return of patients to the UK who may present with post-operative complications involving unknown dental implant systems.

This article will identify simple techniques for practitioners to screen for and manage patients with BDD. CPD/Clinical Relevance: This article addresses the management of patients with a specific psychiatric illness who are likely to present for cosmetic dental treatments.

Cosmetic dentistry: A socioethical evaluation.

Cosmetic dentistry is a divisive discipline. Within discourses that raise questions of the purpose of the dental profession, cosmetic dentistry is frequently criticised on the basis of it being classified as a non-therapeutic intervention. This article re-evaluates this assertion through examination of ethics of care of the self, healthcare definitions and the social purpose of dentistry, finding the traditional position to be wanting in its conclusions. The slide of dentistry from a healthcare vocation towards being a predominantly business-focused interaction between clinician and consumer conflicts with traditional notions of dentistry as a profession. Whilst it is undeniable that cosmetic dental treatment particularly lends itself to the commercial paradigm, this is not exclusive to this area of professional practice. The cultural basis of dental appearance and the potential of the dental profession to exert coercive pressure upon the public to undergo treatment that is based upon social norms is discussed. This essay concludes that cosmetic dentistry is undeniably part of the professional purpose of 21st Century dentistry. However, the caveat that may be placed upon this, is that this status is conditional upon the professional conduct of dental practitioners remaining resilient to commercial practices not compatible with professional obligations.

Simulating Natural Dental Outlook in Esthetic Dentistry: A Case Report

Aesthetic dentistry is concerned not only with the dental appearance but also the enhancement of a person's smile. Creating a natural dental outcome harmonious with adjacent teeth is the main aim of aesthetic dentistry. A good observation, knowledge of dental anatomy and dental materials are required for this. Today's cosmetic dental treatments are more durable and predictable than before with the technological advancements in natural-looking, tooth-colored dental materials. Additionally, more conservative techniques are being used in order to mimic natural dental tissues, depending upon patients’ specific clinical situation. These kind of procedures can be held in a single visit by using aesthetic dental resins mostly without any preparations. This makes direct aesthetic dental rehabilitations such as smile designs more comfortable and convenient for the patients. In this case report a patient with dental aesthetic problems due to crown fractures on maxillary centrals, treated with direct aesthetic composite resin restorations in one appointment. In one-year recall, no discolorations, fractures, secondary caries or soft tissue pathologies were detected and the restorations were almost undetectable resulting in an aesthetic outlook. In conclusion it is considered that natural looking, functional, tooth-colored, seamless, long lasting and aesthetic restorations can be created by using direct aesthetic composite resins that may satisfy the patients’ demands.

Balancing the risks and benefits associated with cosmetic dentistry - a joint statement by UK specialist dental societies.

Cosmetic dentistry has become increasingly popular, largely as a result of social trends and increased media coverage. This understandable desire for the alleged 'perfect smile' needs to be tempered with an appropriate awareness of the significant risks associated with invasive cosmetic procedures such as veneers and crowns. Patients need to be properly informed that elective removal of healthy enamel and dentine can result in pulpal injury and poorer periodontal health in the longer term, particularly if they are young. The duty of candour means that they ought to be informed that aggressive reduction of sound tooth tissue is not biologically neutral and results in structural weakening of their teeth. Less invasive procedures such as bleaching on its own or for example, combined with direct resin composite bonding, can satisfy many patient's demands, while still being kinder to teeth and having much better fall-back positions for their future requirements. It is the opinion of the British Endodontic Society, British Society for Restorative Dentistry, Restorative Dentistry UK, Dental Trauma UK, British Society of Prosthodontics and the British Society of Paediatric Dentistry that elective invasive cosmetic dental treatments can result in great benefit to patients, but that some aggressive treatments used to achieve them can produce significant morbidities in teeth which were previously healthy. This is a worrying and growing problem with many ethical, legal and biologic aspects, but many adverse outcomes for patients who request cosmetic dental improvements are preventable by using biologically safer initial approaches to treatment planning and its provision.

Bolton’s Ratios for Indian Population, Can We Follow The Ideal Standards Blindly?

Introduction: Various studies have been conducted which show that interarch tooth size relation differ with population. The aim of this study was to find out Bolton ratio in Indian population. Methods: Measurement were taken from 50 study models of randomly selected males and females with class I molar and canine relationship with ideal overjet and overbite, who had not undergone any orthodontic or cosmetic dental treatment previously. Needle point dividers were used to measure the greatest mesio-distal diameter of all teeth. From the obtained data, the Kolmogrov-Smirnov test, standard error of mean, standard deviation, coefficient of variation, coefficient of correlation were measured and used to assign statistical significance. Results: Increased anterior ratio (79.2284) & decreased overall ratio (90.9464) in selected Indian population were found in relation to Bolton’s ideal ratio. Conclusions: - Differences between original Bolton ratio and obtained ratio for Indians were significant, specific standards for Indians might be needed.

Cosmetische behandeling van het gebit. Effect op geluksbeleving en levenskwaliteit

This study assessed the impact on happiness and quality of life of the cosmetic treatment of frontal teeth. This was compared with the impact of a restorative, not primarily cosmetic, treatment in the (pre)molar region on happiness and quality of life. The hypothesis that a cosmetic dental treatment makes a person happier or improves the quality of one's life was not supported by the results of the present study. In fact, oral health-related quality of life appeared to decline after the dental cosmetic treatment. Further research is needed to assess whether the results of the present study can be replicated in a larger sample and how the findings can be explained.

Orthodontic treatment of a transmigrated mandibular canine: a case report

The treatment options include: forced eruption of the unerupted tooth using orthodontic traction, autotransplantation, extraction followed by prosthetic replacement. Aim To report the management of a transmigrated lower right canine. Method The treatment involved surgical, orthodontic and cosmetic dental treatment. No permanent teeth were extracted. Results The transmigrated canine was placed between the left central and lateral incisors and the crown recontoured to simulate a lateral incisor. An acceptable aesthetic and functional outcome was gained. Conclusion Transmigration is a rare dental condition that can be treated successfully with a collaborative effort from several dental disciplines.

Study of water diffusion in human dentin by optical coherent tomography

The diffusion of chemical agents in dental tissues is of interest for many problems of dental tissue physiology (diffusion of liquor and water), dental healing (diffusion of preparations), and cosmetic dental treatment (diffusion of whitening agents). The water diffusion in samples of human dentin was monitored using optical coherent tomography (OCT). This diffusion manifests itself as a change in the slope and amplitude of the OCT signal from the sample. It is shown that the average dentin permeability with respect to water is (15.11 ± 21.73) × 10−6 cm/s. These experimental results demonstrate the OCT efficiency for studying the diffusion in hard biological tissues.
