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.

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.

Prevalence and predisponent factors of molar-incisor hypomineralization in primary dentition

Aim: To evaluate the prevalence and predisposing factors for hypomineralization of second molars in children in primary dentition. Methods: A questionnaire was applied to parents to analyze predisposing factors and to assist in the diagnosis of hypomineralization in children between 2 and 6 years old, followed by an intraoral examination based on indices of non-fluorotic enamel defects in the primary dentition, according to the "Modified Index DDE" to determine demarcated opacity and HSPM presence / severity index to assess hypomineralization. Children from public and private schools were dived into two groups: if they presented HSPM-Group 1 (G1) and if they did not have HSPM-Control group (CG). Results: The most frequent predisposing factors associated with the child were Illness in the first year of life (X2= 6.49; p=0.01) and antibiotic use in the first year of life (X2= 41.82; p= 0.01). The factors associated with the mother were hypertension (X2= 9.36; p=0.01), infections during pregnancy (X2=14.80; p=0.01) and alcohol consumption during pregnancy (X2=97.33; p=0.01). There was a prevalence of 3.9% of HSPM in 14 children, with statistical difference regarding gender (X2 = 4.57; p <0.05), with boys presenting a higher frequency. In G1 hypomineralization was of the type with demarcated opacity, with more prevalent characteristics the yellowish spot, with moderate post-eruptive fracture and acceptable atypical restorations. All lesions were located in the labial region with 1/3 of extension. Conclusion: The prevalence of HSPM in children between 2 and 6 years old was 3.9%, with a predominance in males, with tooth 65 being the most affected. There was an association between HSPM and infection in the first year of life, as well as the use of antibiotics and sensitivity in the teeth affected by the lesion. There was an association between HSPM and hypertension, infection and mothers' alcohol use during pregnancy

The midline from the perspective of the layperson and dental surgeon / A linha média na perspectiva do leigo e do cirurgião-dentista

Aim: The objective of this research was to evaluate the midline from the perspectives of the layperson and the dental surgeon. Methods: The survey was conducted from August to December 2018 in Parnaíba, PI, Brazil. An image of a female smile was used, in which changes were made in the upper dental midline, every 1 mm up to 4 mm, and in the incisal angulation, every 5 degrees up to 15 degrees, to the left side. The images were cut and formed into two groups, one showing a smile with no lip filter (G1) and another with a smile with a lip filter (G2). These were then shown to 334 lay people and 25 dentists for evaluation with scores from 0 to 10, with scores from 0 to 5.9 for an unacceptable smile and from 6 to 10 for an acceptable smile. Results:Dental surgeons were more critical when analyzing the images and detected deviations from 1mm and 5 degrees in both groups G1 and G2. Laypeople noticed deviations from 2mm and 15 degrees on G1 and deviations from 3mm and 10 degrees on G2. Conclusion: Dental surgeons and laypeople are able to assess midline deviations with the minimum deviation present. Dentists were more critical in detecting midline deviation when analyzing photos.

Objetivo: Avaliar a linha média sob a ótica do leigo e do cirurgião-dentista. Métodos: A pesquisa foi realizada de agosto a dezembro de 2018 em Parnaíba, Piauí, Brasil. Foi utilizada uma imagem de sorriso feminino, na qual foram feitas alterações na linha média dentária superior, de 1 em 1 mm, até 4 mm, e na angulação incisal, 5 em 5 graus, até 15 graus, para o lado esquerdo. As imagens foram recortadas e formadas em dois grupos, um com sorriso sem filtro labial (G1) e outro com sorriso com filtro labial (G2). Em seguida, foram apresentados a 334 leigos e 25 dentistas para avaliação, com pontuação de 0 a 10, com pontuação de 0 a 5,9 para sorriso inaceitável e de 6 a 10 para sorriso aceitável. Resultados: Os cirurgiões-dentistas foram mais críticos na análise das imagens e detectaram desvios de 1mm e 5 graus nos dois grupos G1 e G2. Os leigos notaram desvios de 2mm e 15 graus no G1 e desvios de 3mm e 10 graus no G2. Conclusão: O cirurgião-dentista e o leigo são capazes de avaliar o desvio da linha média com o desvio mínimo presente. Os dentistas são mais críticos na detecção do desvio de linha média quando analisaram as fotos.

Objetivo: Determinar a prevalência de lesões cervicais não cariosas em crianças na dentição decídua e possíveis fatores etiológicos associados. Métodos:Após a aprovação do Comitê de Ética ­ CEP/UESPI (3.289.732), o estudo transversal foi realizado em 360 crianças com idade entre 2 a 6 anos, de escolas públicas e privadas, divididas em dois grupos: G1 (com lesões cervicais) e G2 (sem lesões cervicais). Foi aplicado um questionário aos pais, seguido do exame clínico das crianças. Foram consideradas lesões detectadas pelo tato e visualmente. 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: Somente lesões do tipo abfração foram encontradas na amostra (5%) e os indivíduos de raça branca apresentaram uma maior prevalência em relação aos demais (55,5%). Houve diferença estatisticamente significativa (p < 0,001) e essas lesões foram identificadas somente em escolas privadas. Quanto ao sexo, em G1, houve diferença estatisticamente significativa, (p = 0,01) com maior prevalência no masculino (66,7%). Os dentes mais acometidos em ordem decrescente foram os caninos e incisivos centrais superiores seguidos dos caninos e incisivos centrais inferiores. Conclusão: A prevalência de lesões cervicais não cariosas, do tipo abfração, em crianças de 2 a 6 anos de idade foi de 5%, tendo sido encontradas somente em escolas privadas, com predominância no sexo masculino. Houve associação entre a abfração e o tipo de escova utilizada na escovação dentária, apresentando maior frequência de lesões quando escovas duras eram utilizadas e escovação forte era executada.

Aim:To determine the prevalence of non-carious cervical lesions in children in the primary dentition and possible associated etiological factors. Method: After approval by the Ethics Committee - CEP / UESPI (3,289,732) ­ this cross-sectional study was carried out on 360 children, from 2 to 6 years of age, from public and private schools, divided into two groups: G1 (with cervical lesions) and G2 (without cervical lesions). A questionnaire was applied to the parents, followed by the children's clinical examination. Lesions detected by touch and visually were considered. Evaluations of means and standard deviations were performed for quantitative variables. Percentages and frequencies were obtained, analyzing the association between qualitative variables based on the chi-square test and comparing the average age using the t test (p < 0.05). Results:Only abfraction-type lesions were found in the sample (5%), and white individuals presented a higher prevalence in relation to the others (55.5%). There was a statistically significant difference (p < 0.001), and these lesions were found only in private schools. As for sex, in G1, there was a statistically significant difference (p = 0.01) with a higher prevalence in males (66.7%). The most affected teeth in decreasing order were the canines and upper central incisors, followed by the canines and lower central incisors. Conclusion: The prevalence of non-carious cervical lesions of the abfraction type in children from 2 to 6 years of age was 5%, which was only found in private schools, with a predominance in males. An association was found between the abfraction and the type of brush used in toothbrushing, with a higher frequency of lesions when hard brushes were used and strong brushing was performed.

Prevalence of sleep bruxism in children in primary dentition

Aim: To evaluate the prevalence of sleep bruxism in children between 2 to 6 years old in primary dentition in a public school (A1) and a private school (A2) in the state of Piauí. Method: It was cross-sectional and quantitative study in 370 participants, 180 in A1 and 190 in A2. The questionnaire to help diagnose bruxism was applied to parents. In the clinical examination, dental wear was evaluated, checking for the presence of shiny and polished facets on deciduous incisors and / or molars (palatal surface, incisal edges and working cusps) and the results were noted in the odontogram. Students who had bruxism participated in group 1 (G1) and those who did not have it were in the control group (CG) in both A1 and A2. Results: One hundred and five children had sleep bruxism. Tooth wear was more prevalent in the male gender. Both in A1 and in A2 and in both genders, wear on primary molars was more frequent than in canines. Conclusion: The prevalence of bruxism in children between 2 and 6 years of age was 28.3%, with a predominance in males. There was an association between sleep bruxism and the habit of sucking a finger, pacifier, bottle use and the habit of awake bruxism. In 98.09% of the children who had sleep bruxism, teeth pain was found

Evaluation of the influence of malocclusion in interpersonal relations among adolescents / Avaliação da influência da má oclusão nas relações interpessoais entre os adolescentes

Aim: To evaluate the influence of malocclusion on interpersonal relationships among adolescents. Method: A cross-sectional, quantitative study was carried out with 360 students. Photographs of male and female mouth with malocclusions were manipulated and superimposed on the smile images of two individuals of both genders with normal occlusion (corresponding to the control group, GC) respectively, for assembly of 4 malocclusions: (1) anterior open bite, ( 2) anterior crossbite (3) dental crowding , and (4) Class II, in this order. These images were provided to the participants, who evaluated them through a questionnaire. Results: The less attractive malocclusion was dental crowding. For both flirting and maintaining a serious relationship the previous open bite was the most rejected, with Class II being the most acceptable. Conclusion: For adolescents, dental crowding is the most appropriate malocclusion to be corrected orthodontically. Malocclusions negatively influence the development of interpersonal relationships among adolescents (AU)

Objetivo: Avaliar a influência da maloclusão nas relações interpessoais entre os adolescentes. Método: Um estudo transversal, quantitativo foi realizado com 360 estudantes. Fotografias de bocas masculina e feminina com maloclusões foram manipuladas e superpostas nas fotos do sorriso de duas pessoas de ambos os gêneros com oclusão normal (correspondendo ao grupo controle, GC) respetivamente, para montagem de 4 maloclusões: (1) mordida aberta anterior, (2) mordida cruzada anterior (3) apinhamento dos incisivos superiores, e (4) Classe II, nesta ordem. Essas imagens foram fornecidas aos participantes, que as avaliaram por meio de questionário. Resultados: A maloclusão menos atrativa foi o apinhamento dentário. Tanto para flertar como para manter um relacionamento sério a mordida aberta anterior foi a mais rejeitada, sendo a Classe II a mais aceitável. Conclusão: Para os adolescentes o apinhamento dentário é a maloclusão mais indicada a ser corrigida ortodonticamente. As maloclusões influenciam negativamente no desenvolvimento das relações interpessoais entre os adolescentes.(AU)

Association between maloclusion and self-perception of oral aesthetics in adolescents

Aim: To evaluate the aesthetic self-perception capacity of adolescents from public schools regarding the presence of oral alterations from malocclusions. Methods: Cross-sectional and quantitative study with 374 adolescents between 16 and 18 years old, belonging to public schools in the city of Parnaíba, Piauí. The adolescents were separated by gender (male and female) and examined for malocclusions. The problem identified for each participant was recorded for later comparison of the influence of its presence with aesthetic self-perception. Then, all adolescents, including those who demonstrated normal occlusion during the clinical evaluation, answered a questionnaire containing eight questions about their perception of their own smile and its impact on their interpersonal relationships. Self-perception was also analyzed by comparing the responses of those with normal occlusion with that of malocclusion individuals. Student's t-tests were used to verify if there was a difference between the groups. Results: The most prevalent malocclusions after clinical examination were midline deviations, crowding and diastemas, and the ones that most scored in the adolescents' perception were crowding, misalignment and diastemas. Conclusion: The adolescents were able to perceive the aesthetic alterations resulting from malocclusions, being determinants of dissatisfaction when smiling. They were not ashamed to smile, did not consider that the ideal smile would improve their self-esteem and that misaligned teeth would not interfere with flirting and interpersonal relationships

White spots on tooth enamel in mixed dentition / Manchas brancas em esmalte dentário na dentição mista

Aim: To determine the prevalence, predisposing factors of white spots on enamel and the effectiveness of treatment using the microabrasion technique. Method: A study was developed in children between the ages of 6 and 12 of both genders, enrolled in municipal public schools. Epidemiological questionnaire was applied to the participants and parents or guardians to investigate the predisposing factors of the lesions on permanent teeth during the mixed dentition. Oral examination of the children was carried out, and for those children in whom white spot lesions were found, dental treatment was provided by the microabrasion technique in the incisors and/ or first permanent molars to prevent the evolution to a caries lesion with cavitation, since the enamel structure was damaged. Results: The majority of the sample had from 1% to 24% of the enamel affected by the white spots. The possible predisposing factors of white spots were systemic infections, trauma or caries with pulp involvement in a deciduous tooth. The treatment was effective in 16 children and for the remaining two the restorative treatment was performed. Conclusion: The prevalence of white spot lesions found in enamel was 3.95%, with a higher prevalence in females. Regarding predisposing factors, most children had some infectious diseases and frequently took antibiotics and anti inflammatory drugs. The permanent right upper central incisor was the most affected. The treatment proved to be effective in most children possibly because the lesion is located more superficially in the enamel (AU)

Objetivo: Determinar a prevalência, os fatores predisponentes de manchas brancas no esmalte dentário e a eficácia do tratamento pela técnica de microabrasão. Método: Foi desenvolvido um estudo em crianças na faixa etária dos 6 aos 12 anos de ambos os gêneros, matriculados em 3 escolas públicas municipais. Questionário epidemiológico foi aplicado aos participantes e aos pais ou responsáveis para investigar os fatores predisponentes das lesões em dentes permanentes durante a dentição mista. Realizou-se o exame bucal das crianças e nas que foram constatadas lesões de mancha branca foi proporcionado o tratamento odontológico pela técnica de microabrasão, nos incisivos e/ou primeiros molares permanentes, impedindo a evolução para uma lesão de cárie com cavitação, uma vez que a estrutura do esmalte estava danificada. Resultados: A maioria da amostra apresentou de 1% a 24% do esmalte atingido pelas manchas brancas. Os possíveis fatores etiológicos das manchas brancas foram infecções sistêmicas, trauma ou cárie com envolvimento pulpar em dente decíduo. O tratamento foi eficaz em 16 crianças e em duas restantes foi realizado o tratamento restaurador. Conclusão: A prevalência de lesões de manchas brancas encontradas em esmalte foi 3.95% com maior predominância no gênero feminino. Com relação aos fatores predisponentes, a maioria das crianças tiveram algumas doenças infecciosas e fizeram uso de antibióticos e anti-inflamatórios. O incisivo central superior direito permanente foi o mais acometido. O tratamento mostrou-se eficaz na maioria das crianças, possivelmente devido à localização da lesão ser superficial no esmalte (AU)

Deciduous tooth early loss prevalence in posterior region and indication of band-loop space maintainer / Prevalência da perda precoce de dente decíduo na região posterior e indicação de mantenedor de espaço banda-alça

Objective: To investigate the prevalence of the early unitary loss of deciduous and the need for space maintainer in the posterior region, of the band-loop type. Material and Methods: The clinical examination by two examiners of 568 children between 6 and 12 years of age in mixed dentition was performed in two municipal schools. After the diagnosis of premature loss of one or two deciduous molars (unilateral, one or both arches, respectively), without successors initiating the eruptive process in the oral cavity, the child was referred to the Clinical School of Dentistry (CSD) of State University of Piauí (UESPI) for installation of the band-handle space maintainer. Results: The prevalence of early deciduos molar loss was 4.04%, from 568 children examined, being 15 in the lower arch and 8 in the upper arch of 23 children, mean age of 10 ± 2 years with predominance of the first deciduos molars (10 in the lower arch and all 8 in the upper arch). The etiological factor of which was dental caries for all sample, according to the parents or guardians. Only 13 attended the CSD for detailed examination. After radiographic examination, it was verified that 8 did not need space maintainers because they were approximately 2/3 of the permanent successors root formation. In 5 children was placed the maintainer of space, band-handle, who are being supervised every 3 months until the eruption of the permanent successors. Conclusion: The prevalence of early molar loss was 4.04% with no statistical difference between genders. The use of space maintainers after the early loss of a deciduous tooth is a preventive measure of malocclusion, being the band-loop appliance an excellent choice after loss of the deciduous unilateral molar.(AU)

Objetivo: Investigar a prevalência a perda precoce unitária de decíduo e a necessidade de mantenedor de espaço na região posterior do tipo banda-alça. Material e Métodos: O exame clínico realizado por dois examinadores de 568 crianças de 6 a 12 anos de idade na dentição mista foi realizado em duas escolas municipais. Após o diagnóstico de perda precoce de um ou dois molares decíduos (unilateral, de uma ou ambas arcadas, respectivamente), sem que os sucessores tivessem iniciando o processo eruptivo na cavidade bucal, a criança foi encaminhada à Clínica Escola de odontologia (CEO) da Universidade Estadual do Piauí (UESPI) para instalação do mantenedor de espaço banda-alça. Resultados: A prevalência da perda precoce de molar decíduo foi de 4.04%, de 568 crianças examinadas, sendo 15 na arcada inferior e 8 na arcada superior de 23 crianças, com idade média de 10 ± 2 anos com predomínio dos primeiros molares decíduos (10 no arco inferior e todos os 8 no arco superior). O fator etiológico foi cárie dentária para toda a amostra, segundo os pais ou responsáveis.Somente 13 compareceram à CEO para exame detalhado. Após exame radiográfico constatou-se que 8 não precisavam de mantenedores de espaço pois estavam aproximadamente com 2/3 de formação radicular dos sucessores permanentes. Em 5 crianças colocou-se o mantenedor de espaço, bandaalça, que estão sendo supervisionadas a cada 3 meses até a erupção dos sucessores permanentes. Conclusão: A prevalência da perda precoce de molar decíduo foi de 4.04% sem diferença estatística entre os gêneros. O uso de mantedores de espaço após a perda precoce de dente decíduo é uma medida preventiva da má oclusão, sendo a banda-alça excelente opção após a perda do molar decíduo unilateral(AU)

Anterior crossbite malocclusion: prevalence and treatment with afixed inclined plane orthodontic appliance

Aim: To evaluate the prevalence of anterior crossbite and to verify the effectiveness of the orthodontic appliance Inclined Plane in the correction of this malocclusion. Methods: The clinical examination was performed 702 children in the deciduous or mixed dentition of 7 schools and in those found the anterior crossbite was performed treatment with fixed Inclined Plane. Results: The prevalence of the anterior crossbite was 2.14%, characterizing 15 of the 702 children evaluated, of which 60% were female and 40% male, all of which were dental crossbites. Only 12 accepted the treatment with an average duration of 4.4 weeks. Conclusion: The prevalence of anterior crossbite was 2.14%. The inclined plane proved to be a viable and effective therapy in the correction of anterior crossbite. It is one of the options of the orthodontic treatment in patients in the deciduous or mixed dentition, propitiating greater possibility of dentoskeletal development, since the malocclusion is corrected. However this method needs to be correctly indicated and its execution technique rigorously followed

Prevalence and etiology of dental trauma in schoolchildren aged 6 to 12 years

Aim: To investigate the prevalence and etiological factors of dental trauma in school-age children aged 6 to 12 years. Methods: A study was developed in children and adolescents between the ages of 6 and 12 of both genders enrolled in 3 municipal public schools. An oral examination of the permanent or deciduous incisors was performed, if they were still present in the oral cavity, to evaluate the presence of dental trauma, need for treatment and sequels, and the method of examination and classification of dental trauma of O'Brien. Results: The prevalence of dental trauma was 4.03% (n=29). The most verified traumas were enamel crack / enamel fracture and enamel / dentin fracture without pulp exposure. It was observed that the most affected teeth were the permanent upper central incisors and the age at which trauma was most observed was 11 years, the main etiological factor was fall from a height, in 65.3% of schoolchildren (n=19). Conclusion: The prevalence of dental trauma was 4.03%, with no statistically significant difference between genders. The permanent right upper central incisor was the most affected, occurring predominantly at home and at school. The dissemination of information about dental trauma and emergency protocols to parents and teachers need to be encouraged

Relationship between oral candidiasis and users of dental prostheses

Aim: To investigate the relationship between oral candidiasis and users of dental prostheses. Methods: A cross-sectional study was carried out which the inclusion of adults and elderly people of both genders using dental prostheses. Lectures were given with guidelines on oral hygiene techniques and dental prostheses, preventive measures of candidiasis, highlighting their influence on the oral and general health of the individual for the 240 users of dental prostheses. Of this number, 153 did not want to participate in the clinical examination. Signals and symptoms were analyzed in 87 patients, and lesions were present in only 21, and a cytological complement of the lesions was performed. Data were analyzed using SPSS version 15.0 with Chi-square (χ2 ) test at p < 0.05. Results: The 21 patients presented oral candidiasis, with erythematous (prosthetic) stomatitis being the most prevalent. There was a correlation between the presence of Candida and the use of prostheses (p- value 0.00*). Candidiasis was associated with poorly adapted prostheses, poor oral hygiene, inadequate prostheses and prolonged use of them. Conclusion: There was a correlation between oral candidiasis and users of dental prostheses. The most prevalent type of candidiasis was erythematous stomatitis (prosthetic), and nystatin was used to treat all cases. The preventive activities carried out were extremely important, since patients were not aware of oral candidiasis and the factors that trigger it, such as poor oral hygiene and dental prostheses

Intrusion of upper molars with mini-implants for open bite correction is effective? A systematic review / A intrusão de molares superiores com mini-implantes para correção da mordida aberta é eficaz? Revisão sistemática

Introduction: The open bite is a malocclusion defined by the absence of a positive vertical overlap of the upper incisors over the lower ones. It is believed that the correction of this malocclusion with mini-implants is as effective as another technique. Objective: To verify by scientific evidence the effectiveness of upper molar intrusion with mini-implants for correction of open bite. Material and Methods: This systematic review was conducted according to the PRISMA guidelines. Cochrane Handbook for Systematic Reviews of Interventions (version 5.3) was used to assess the methodological quality and risk of bias of the included studies. Results: During the selection and evaluation process, 795 of the 1297 papers were eligible for research in their titles and abstracts. Repeated articles were removed and as a result, 21 articles were retrieved and read completely. Those who did not meet the inclusion criteria were excluded, resulting in only 6 articles that were included. Conclusion: The intrusion of the upper molars with the use of mini-implants as a skeletal anchor is effective for open bite correction. When the technique of upper molar intrusion with mini-implants was compared with the technique of posterior high pull and incisor extrusion, the first one was more effective for the correction of open bite. The recurrence of molar intrusion does not invalidate mini-implant treatment for open bite correction because the benefits achieved outweigh the small dental relapse. (AU)

Introdução: A mordida aberta é uma má oclusão definida pela ausência de um trespasse vertical positivo dos incisivos superiores sobre os inferiores. Acredita-se que a correção desta má oclusão com mini-implantes seja tão eficaz quanto outra técnica. Objetivo: Constatar por evidências científicas a eficácia da intrusão dos molares superiores com mini-implantes para correção da mordida aberta. Material e Métodos: Esta revisão sistemática foi conduzida de acordo com as diretrizes PRISMA. Para avaliar a qualidade metodológica e o risco de viés dos estudos incluídos, utilizou-se a Ferramenta Cochrane de Colaboração para avaliação do risco de viés, publicado Cochrane Handbook for Systematic Reviews of Interventions (versão 5.3). Resultados: Durante o processo de seleção e avaliação, 795 dos 1297 artigos mostraram-se elegíveis para a pesquisa em seus títulos e resumos. Os artigos repetidos foram removidos e como resultado, 21 artigos foram recuperados e lidos por completo. Aqueles que não preencheram os critérios de inclusão foram excluídos, resultando em apenas 6 artigos que foram inclusos. Conclusão: A intrusão dos molares superiores com o uso de mini-implantes como ancoragem esquelética é eficaz para correção de mordida aberta. Quando a técnica de intrusão de molares superiores com miniimplantes foi comparada com a técnica de puxada alta posterior e extrusão de incisivos, a primeira foi mais eficaz para correção da mordida aberta. A recidiva da intrusão dos molares não invalida o tratamento com mini-implantes para correção da mordida aberta porque os benefícios alcançados superam a pequena recidiva dentária (AU)

Dental caries in children on deciduous dentition: art and socioeconomic aspect

Aim: Determine the prevalence and incidence of dental caries in children´s deciduous teeth, who were treated with ART technique. Methods: In T1, 62 children were examined for being between 3 and 6 years of age. A questionnaire was applied to the parents or guardians of the children involved in the research, to analyze their knowledge about eating habits and oral hygiene. An intra-oral examination of children from 3 to 6 years old was carried out and dental treatment was performed by the ART technique. Six months after,(T2), the clinical examination was redone to investigate the restorations´stability. Results: In T1, 94 carie cavities were found in 19 children and 86 were recommended for restoration with ART. In T2, 58 restorations were damaged or lost and 15 children had 20 new carie cavities. Conclusion: The prevalence of dental caries in the deciduous dentition was 38.8% and the incidence was 31.9%. In T2, the majority restorations class I and II were damaged or lost. ART technique is an option, despite the high failure in ART, especially for child population with deciduous teeth that has limited access to dental services. However, restorations should be supervised and healthy eating habits implemented (AU)
