Aesthetic perceptions and social judgments about different enamel opacities

Abstract This study aimed to evaluate adolescents' aesthetic perceptions and their social judgments regarding different enamel opacities. Sample size was calculated and resulted in the inclusion of 100 adolescents (aged 10 to 15 years) from a public school in Jequié, Bahia, Brazil. Images of enamel opacities were manipulated to create aesthetic enamel defects, such as enamel color changes (unilateral and bilateral white opacity, unilateral and bilateral yellowish opacity, and unilateral and bilateral yellowish opacity with loss of structure). The images of the opacities were based on Fédération Dentaire Internationale's Developmental Defects of Enamel (DDE) Index. Aesthetic perception and social judgments were evaluated using a validated questionnaire with 12 questions (six positive and six negative points) on social aspects, considering the six manipulated images and the control. The photographic analyses were projected one-by-one by computer to adolescents individually in a classroom. Participants had one minute to observe each image and answer the questionnaire. The data were analyzed by descriptions, and the Friedman Wilcoxon test (p < 0.05). The results indicate that all opacities negatively impacted social judgment (p < 0.001). The enamel aesthetic defects most affecting an individual's perception were bilateral yellow opacity with or without loss of structure (p < 0.001). Regarding social judgment, all participants showed a negative perception of all the tested opacity types (p < 0.001). In conclusion, even opacities presenting only a color change caused aesthetic dissatisfaction to the individuals and changes in their social judgment toward others. Color changes in dental enamel have several aesthetic consequences.

Concerns about dental aesthetics are associated with oral health related quality of life in Southern Brazilian adults / Preocupações sobre a estética dentária com qualidade de vida relacionada à saúde bucal em adultos no sul do Brasil

Abstract It aims to evaluate the association between dental appearance and Oral Health Related Quality of Life. Fifteen primary care services with dental services were selected in Porto Alegre, Brazil. Individuals were interviewed from a random sampling of households in the catchment area of the health centres. The outcome was having an OHIP14 score > 0 (any impact). The main exposures included self-reported tooth colour and position, perception of oral health and concern with dental aesthetics. Data were analysed with stepwise logistic regression. Of 1943 individuals contacted, 433 used public dental services in the last year. Seventy-three percent had some impact on quality of life, 35.2% and 47.5% reported stained and crowded teeth, respectively. Also, 22.2% had already tried bleaching their teeth. Individuals concerned with colour were 2.56 times (95% CI: 1.34-4.89) more likely to report any impact after adjusting for number of teeth, smoking and education. Concerns about tooth position, reporting stained or crowded teeth, age, sex and income were not significant (p > 0.30). There is a direct and independent association between concerns with tooth colour and quality of life. The effect of tooth colour on quality of life may be mediated by individuals' perceptions of aesthetics.

Resumo O objetivo do presente estudo foi avaliar a associação entre a aparência dos dentes com a qualidade de vida relacionada à saúde bucal. Quinze centros de atenção primária com serviços odontológicos foram selecionados em Porto Alegre, Brasil. Os indivíduos foram entrevistados a partir de uma amostragem aleatória de domicílios. O desfecho avaliado foi ter um escore de OHIP14 > 0. As exposições foram: cor e posição autorreferida dos dentes, percepção da saúde bucal e preocupação com a estética dental. Os dados foram analisados com regressão logística. De 1.943 indivíduos contatados, 433 utilizaram os serviços públicos odontológicos, dos quais 73% tinham algum impacto na qualidade de vida; 35,2% dentes manchados e 47,5% dentes apinhados. Além disso, 22,2% já haviam tentado clarear os dentes. Indivíduos preocupados com a cor tinham 2,56 vezes (IC 95%: 1.34-4.89) mais chances de relatar qualquer impacto após o ajuste para número de dentes, tabagismo e educação. Preocupações com a posição dos dentes, relato de dentes manchados ou apinhados, idade, sexo e renda não foram significativas (p > 0,30). Houve uma associação direta e independente entre as preocupações com a cor do dente e qualidade de vida. O efeito da cor do dente pode ser mediado pela percepção da estética.

Dental esthetic satisfaction, received and desired dental treatments for improvement of esthetics.

Aim: The purposes of this research were to investigate factors influencing patients' satisfaction with their present dental esthetic, received previous dental treatments on anterior teeth and basic treatments that they wanted to undergo to improve their dental appearance. Materials and Methods: A total of 1014 patients who attended a dental school in a major city in Turkey participated in the study. The participants were surveyed with a questionnaire containing questions about gender, age, education level, self-reported tooth appearance, received previous dental treatments on anterior teeth and desired basic esthetic dental treatments. Statistical analysis of the verifying data was made with descriptive statistics, χ2 test and multiple logistic regression analyses. Results: According to the analyses of the verifying data, 55.1% of the patients were dissatisfied with the color of their teeth, 42.7% with dental appearance, 29.9% with crowding of anterior teeth, 23.3% were hiding teeth while smiling, 16.1% had non-esthetic restorations and 11.9% thought that their anterior teeth were protruding. Esthetic restoration was found to be the most-performed treatment recently (29.0%) and whitening of teeth was the most-desired dental treatment (49.0%). Gender, age and education level had an effect on satisfaction and received previous and desired dental treatments for improvement of esthetics. Conclusion: Many of the Turkish patients surveyed in the study were dissatisfied and desired the improvement of dental esthetics. Therefore, dentists should consider this as an important dimension in their practice.
