Prevalence and factors associated with gummy smile in adolescents: a cross-sectional analysis

Aim: To evaluate the prevalence and factors associated with gummy smiles in adolescents aged between 15 and 18 years attending high school. Methods: The cross-sectional and quantitative study was carried out during the Covid-19 pandemic, with 160 adolescents, from two public (A1) and two private (A2) schools chosen by lottery, divided into two groups: G1 (with gummy smile) and G2 (no gummy smile). A clinical examination was carried out on the adolescents, investigating the presence or absence of a gummy smile (GS), by analyzing the variables (interlabial distance at rest, upper incisor exposure at rest, smile arc, measurement from the subnasal to the upper lip philtrum, upper lip length, upper lip thickness, hypermobility and lower/middle third ratio). Means and dispersion were obtained, and the Chi-square association test was applied, to compare the results between A1 and A2 and between G1 and G2. Results: The prevalence of GS was 33.8% (=54). It was found that no statistically significant associations were found (p > 0.05), regarding the type of school and gender with the presence of GS in adolescents. There was no statistically significant difference (χ² = 1.82; p = 0.07) between the groups and the age of adolescents. There was a significant association between the studied variables and GS (p < 0.05). Conclusion: The prevalence was high with a predominance of females. There were no statistically significant associations regarding the type of school and gender, but there was a significant association between gummy smile and lip dimensions

Prevalence and influence of dental development anomalies in smile esthetics: a cross-sectional analysis

Aim: To determine the prevalence of dental development anomalies and type of influence on the smile of adolescent students. Method: This was a cross-sectional and analytical study carried out in two public (A1) and two private (A2) schools chosen by lot in the city of Parnaíba-Piauí. The sample calculation was based on the target population: number of people enrolled in public and private schools between 15 and 19 years, in the city of Parnaíba-PI, which totaled 6209 students in 2020, according to a survey carried out by the Brazilian Institute of Geography and Statistics ­ IBGE. A questionnaire on epidemiological data and aesthetic self-perception of the smile was applied to 160 adolescents between 15 and 19 years old, from August 2020 to July 2021. The clinical examination was carried out under natural light, to check for the presence of anomaly(s) in the dental development. Students who presented only one pathology would be called group 1 (G1), those who presented two would be called group 2 (G2) and those who presented 3 or more would be called group 3 (G3). On the other hand, adolescents in whom no anomaly was evidenced would participate in the control group (CG), both in A1 and A2. Results: It was observed that 37.5% of the sample had only a type of dental anomaly, corresponding to 60 individuals. The most prevalent were enamel hypoplasia, fusion, transposition, agenesis, ectopic eruption, microdent and dens-in-dent. It was possible to verify a higher prevalence in the maxilla, private schools (76.6%) and females (86.6%). In 45% of adolescents with dental anomalies, embarrassment was observed when smiling. Conclusion: The prevalence was relatively high, highlighting the enamel hypoplasia, influencing the smile esthetics of a reasonable number of adolescents, whether for acquaintances, strangers or even for photographs

Selamento de lesões cariosas em molares decíduos / Sealing of carious lesions in deciduous molars

Objetivo:Investigar a eficácia do selamento de lesão de cárie dentinária em comparação com a remoção parcial de cárie seguida de restauração em molares decíduos. Material e Método: O estudo clínico randomizado foi planejado ser realizado em 60 crianças com idade entre 3 e 8 anos. As crianças foram randomizadas por sorteio, com alocação para os 3 grupos, sendo 20 em cada grupo: Grupo 1 (G1) constituído por crianças que receberam o selamento de cárie com resina fluida; Grupo 2 (G2) com crianças que receberam o selamento de cárie com cimento de ionômero de vidro de alta viscosidade e Grupo controle (G3) com crianças onde a remoção parcial da cárie foi seguida por restauração com cimento de ionômero de vidro resinoso. Foram feitos acompanhamentos clínicos e radiográficos antes e após a intervenção, bem como a cada 4 meses durante 1 ano, investigando-se se houve fratura no selamento ou na restauração (infiltração marginal), paralização, regressão ou evolução do processo carioso nos 3 grupos. Resultados: A amostra foi reduzida para 49 crianças pois durante a fase de controle clínico radiográfico, 11 não foram localizadas por mudança de endereço.O grupo G1 apresentou 50% dos casos com regressão e 50% dos casos em paralização. O grupo G2 apresentou 62,5% dos casos com regressão e 37,5% dos casos com paralização e o grupo G3 com 60% dos casos com regressão e 40% com paralização. Não houve associação estatisticamente significativa entre o tipo de grupo e a progressão da lesão, não havendo diferença entre os grupos (valor de p = 0,74). Conclusão: Não houve diferença entre os grupos quanto à progressão de lesão de cárie quando tratados somente com o selamento com resina fluida ou com cimento de ionômero de vidro de alta viscosidade ou com restauração convencional com cimento de ionômero de vidro resinoso após a remoção do tecido cariado.

Aim: To investigate the effectiveness of sealing a dentin caries lesion compared to the removal of partial caries followed by restoration in deciduous molars. Methods: The randomized clinical trial was planned to be performed on 60 children, aged 3 to 8 years. Children were randomized by lot, with allocation into 3 groups, 20 per group: Group 1 (G1) consisted of children who received a sealing of caries using fluid resin; Group 2(G2) included children who received the sealing of caries performed with high viscosity glass ionomer cement, and Group 3(G3) conducted with children where the removal of partial caries was followed by restoration with resinous glass ionomer cement. Clinical and radiographic follow-ups were performed before and after the intervention, as well as every four months for one year, investigating whether there was a fracture in the sealing or restoration (marginal infiltration), paralysis, regression, or evolution of the carious process in the three groups. Results: The sample was reduced to 49 children given that, during the radiographic clinical control phase, 11 were not located due to a change of address. The G1 group presented 50% cases with regression and 50% cases with paralysis. The G2 group presented 62.5% of the cases with regression and 37.5% of the cases with paralysis, while the G3 group showed 60% of the cases with regression and 40% with paralysis. There was no statistically significant association between the type of group and the progression of the lesion, with no difference found between the groups (p value=0.74). Conclusion: There was no difference between the groups regarding the progression of carious lesions when treated only with fluid resin sealing or with high viscosity glass ionomer cement or with conventional restoration with resinous glass ionomer cement after the removal of decayed tissue.

Impacto da presença de diastema na autopercepção do sorriso em uma amostra de adolescentes / Impact of the presence of diastema on the self-perception of one's smile in a sample of adolescents

Objetivo: Verificar a prevalência de diastema em adolescentes, analisar fatores associados e investigar o impacto dessa má oclusão na autopercepção dos adolescentes em relação ao seu sorriso. Métodos:A amostra consistiu em 160 adolescentes. Tratou-se de um estudo transversal e quantitativo realizado em escolas privadas (A1) e públicas (A2), no período de agosto de 2020 à julho de 2021, na cidade de Parnaíba, Piauí. Inicialmente, aplicou-se um questionário epidemiológico. A seguir, o exame clínico foi realizado sob luz natural, em ambiente escolar. Os alunos que apresentaram diastema constituíram o grupo G1 e os que não apresentaram formaram o grupo G2. Nos alunos do G1 foram identificadas a localização e a medida do diastema e dos possíveis fatores associados e aplicado um segundo questionário sobre a auto avaliação estética do sorriso. Foram realizadas estatísticas descritivas, obtendo-se porcentagens, frequências e análises de associação com o teste qui-quadrado e comparações de média a partir do teste t. Resultados:Houve diferença significativa na distribuição de adolescentes quanto ao tipo de escola e presença de diastema, verificando-se maior prevalência na escola pública. Quanto ao gênero, não foi encontrada diferença estatisticamente significativa, assim como não houve associação entre o sorriso e a presença de diastema, pois a maioria não apresentava vergonha ao sorrir, estava satisfeita e julgava ter um sorriso agradável. Verificou-se, quanto aos fatores associados, uma distribuição significativa com maior prevalência de "discrepância de tamanho dentário". Conclusão: A presença de diastema teve como fator associado predominante, a discrepância de tamanho dentário. A maioria dos adolescentes afirmaram estar satisfeitos com o sorriso, apesar de não ser agradável, considerando desnecessário o tratamento.

Aim: To verify the prevalence of diastema in adolescents, analyze associated factors, and investigate the impact of this malocclusion on adolescents' self-perception of their smile. Methods:The sample consisted of 160 adolescents. This was a cross-sectional and quantitative study carried out in private (A1) and public (A2) schools, from August 2020 to July 2021, in the city of Parnaíba, Piauí, Brazil. Initially, an epidemiological questionnaire was applied. The clinical examination was then performed under natural light, in a school environment. Students who presented diastema formed the G1 group, and those who did not, formed the G2 group. In G1 students, the location and measurement of the diastema and possible associated factors were identified and a second questionnaire was applied on the self-assessment of the esthetic smile. Descriptive statistics were performed, obtaining percentages, frequencies, and association analysis using the chi-square test and mean comparisons using the t test. Results: There was a significant difference in the distribution of adolescents regarding the type of school and presence of diastema, with a higher prevalence in public schools. Regarding gender, no statistically significant difference was found. There was also no association between smiling and the presence of diastema, as most were not ashamed to smile, were satisfied, and thought they had a pleasant smile. Regarding the associated factors, there was a significant distribution with a higher prevalence of "tooth size discrepancy". Conclusion: The presence of diastema was predominantly associated with tooth size discrepancy. Most adolescents said they were satisfied with the smile, despite not being pleasant, considering the treatment unnecessary.

Consumo de álcool como fator de risco para traumatismo dentário em adolescentes: estudo caso-controle / Alcohol consumption as a risk factor for dental trauma in adolescents: a case-control study

Objetivo: Avaliar a ingestão de álcool como fator associado ao traumatismo dentário em adolescentes. Método: O estudo transversal de caso-controle foi realizado em 160 adolescentes com idade entre 14 a 19 anos, de escolas públicas e privadas, divididas em grupos, sendo (G1) o grupo com traumatismo dentário e (G2) o grupo controle. Um questionário foi aplicado para cada participante sobre os dados epidemiológicos e posteriormente, foi aplicado um segundo questionário somente para os alunos expostos à bebida alcóolica, para informações detalhadas sobre o consumo. Em seguida, o exame clínico foi realizado em toda a amostra. Foram considerados traumas dentários, os detectados pelo tato e visão. Foram realizadas avaliações das médias e dos desvios padrão para variáveis quantitativas. Obteve-se porcentagens e frequências, realizando-se análises de associação entre as variáveis qualitativas a partir do qui-quadrado e comparação da idade média a partir do teste t (p < 0,05). Resultados: Com base nos dados coletados em 160 adolescentes, foi possível observar uma taxa de 34,37%, (n = 55) de adolescentes com traumatismo dentário. Quanto à distribuição do consumo de bebidas alcóolicas, observou-se que, 20 desses 55 adolescentes faziam uso de consumo de bebidas alcoólicas regularmente. Conclusão: Em adolescentes, com idade entre 14 e 18 anos, que consumiam bebidas alcóolicas, a prevalência de traumatismo dentário (TD) foi de 33,3%, com predominância no gênero feminino. Houve associação do consumo de álcool com TD nas idades entre 16 e 18 anos. Em escola privada foram observados 70% dos casos provenientes de TD associados ao uso de bebidas alcóolicas.

Aim: To evaluate alcohol intake as a factor associated with dental trauma in adolescents.Methods: This work is a cross-sectional case-control study was carried out with 160 adolescents, aged 14 to 19 years, from public and private schools, divided into 2 groups: G1 ­group with dental trauma and G2 ­ control group. A questionnaire was applied to each participant concerning the epidemiological data. Later, a second questionnaire was applied only to students exposed to alcohol in order to find detailed information about consumption. The clinical examination was then performed on the entire sample. Dental traumas were those detected by touch and vision. Evaluations of means and standard deviations were performed for quantitative variables. Percentages and frequencies were obtained by performing an analysis of association between qualitative variables using the chi-square test and comparing the mean age using the t test (p < 0.05).Results: Based on data collected from 160 adolescents, it was possible to observe a rate of 34.37% (n = 55) of adolescents with dental trauma. As for the distribution of alcohol consumption, it was observed that 20 of these 55 adolescents used alcohol regularly.Conclusion:In adolescents, aged 14 to 18 years, who consumed alcoholic beverages, the prevalence of dental trauma (DT) was 33.3%, with a predominance found in females. There was an association between alcohol consumption and DT at ages between 16 and 18 years. In a private school, 70% of the cases of DT associated with the use of alcoholic beverages were observed.
