ABSTRACT

Este trabajo tuvo como objetivo evaluar características de la sonrisa en pacientes con necesidad de tratamiento ortodóntico. Como objetivos específicos, se planteó estudiar el arco de la sonrisa, la línea del labio superior y los corredores bucales, que son tres componentes importantes a la hora de elaborar un plan de tratamiento adecuado para devolver al paciente una sonrisa funcional y estéticamente aceptable. La muestra quedó conformada por 157 pacientes; de cada uno de ellos se obtuvo una foto de una sonrisa voluntaria. Se encontró que el arco de la sonrisa, en el 39,5 %, presentaba un arco consonante; un 20,4 %, uno plano y el 40,1 % restante, uno no consonante. Al estudiar la línea del labio superior, se observó que, en el 8,3 %, la línea era baja; en el 62,4 %, media y en el 29,3 %, alta. En cuanto a los corredores bucales, se observó que el valor medio, en proporción a la distancia intercomisural del corredor bucal total, era de 15,89 % ± desvío estándar (5,03 %); el valor total máximo, 26,19 % y el valor mínimo, 2,74 %. Conociendo la prevalencia de cada uno de estos datos, se podrá arribar al diagnóstico y posterior plan de tratamiento para cada paciente de manera individualizada(AU)


This work aimed at evaluating smile characteristics in patients in need of orthodontic treatment. As specific objectives, it was raised the issue of studying the smile arch, upper lip line and buccal corridors, which are three important components when preparing an adequate treatment plan to restore the patient a functional and aesthetically acceptable smile. The sample consisted of 157 patients and a photo of a voluntary smile was obtained from each of them. It was found that the smile arch had a consonant arch in 39.5%, 20.4% a flat arch and the remaining 40.1% a nonconsonant arch. When studying the upper lip line, it was observed that in 8.3% the line was low, 62.4% medium and 29.3% high. As regards the buccal corridors, it was observed that the mean value in proportion to the intercommissural distance of the total buccal corridor was 15.89% ± standard deviation (5.03%); maximum total value was 26.19% and minimum value 2.74%. Knowing about the prevalence of each of these data, it will be able to arrive at the diagnosis and subsequent treatment plan for each patient individually(AU)

ABSTRACT

Objetivo: Presentar un caso clínico en el que el paciente cursa impétigo que podría estar relacionado con el uso de mascarillas faciales por un tiempo prolongado. Caso clínico: Se reporta el tratamiento y la evolución de un caso clínico en un paciente adulto que consultó en un centro clínico privado por la presencia de lesiones vesiculares en la región labial superior con aumento de volumen generalizado en ambos labios. El cuadro clínico es compatible con infección por impétigo y herpes zóster asociado al uso prolongado de una mascarilla de tela. Se describe la importancia del empleo correcto de estas mascarillas que se están usando como medida de protección personal en el contexto de la pandemia por COVID-19, ya que las mismas pueden contribuir a generar infecciones faciales si no se mantiene una higiene apropiada (AU)


Aim: To present a clinical case in which the patient has impetigo that could be related to the use of facial masks for a long time. Clinical case: The treatment and evolution of a clinical case of an adult patient who attended a private clinical centre due to the presence of vesicular lesions in the upper labial region with generalized increase volume in both lips is reported. The clinical presentation is compatible with impetigo and herpes zoster infection associated with prolonged use of a cloth mask. The importance of the correct use of cloth masks that are being used as a personal protection measure in the context of the COVID-19 pandemic is described, since they can contribute to facial infections if proper hygiene is not observed (AU))

ABSTRACT

Los labios son repliegues músculo membranosos móviles que se encuentran en la entrada de la cavidad oral, y tienen como funcionalidad proporcionar competencia para la cavidad oral durante la masticación y el reposo. Bozzola y cols., en 1989, describieron la arteria bucal como el principal pedículo para el músculo buccinador. El objetivo de este trabajo es demostrar la efectividad del colgajo miomucoso del buccinador para reconstrucción del labio inferior en un paciente con hemangioma congénito. Este es un estudio longitudinal de tipo retrospectivo, con resultado descriptivo, que se le realizó a un paciente masculino de 32 años, para cubrimiento de defecto de lesión en labio inferior secundario a hemangioma congénito utilizando la reconstrucción con colgajo miomucoso del buccinador. El colgajo miomucoso del buccinador o colgajo yugal se considera uno de los mejores colgajos locales para la reconstrucción del labio inferior, sea cual fuere la causa, por su fácil disección y versatilidad debido a que tiene una tasa de sobrevida muy elevada con mínimas complicaciones en el posoperatorio. Nuestros resultados obtenidos concuerdan con los resultados ya publicados por diferentes autores, que llegan a las mismas conclusiones; aunque existen varias técnicas con colgajos locales para la reconstrucción del labio inferior, el colgajo del músculo buccinador o yugal se considera como una de las principales alternativas, ya que puede lograrse un labio funcional y estético.


The lips are mobile muscle membranous folds, found at the entrance of the oral cavity, whose function is to provide competition for the oral cavity during chewing and rest. Bozzola et al. in 1989, they described the buccal artery as the main pedicle for the Buccinator Muscle. The objective of this work is to demonstrate the effectiveness of the buccinator myomucosal flap for reconstruction of the lower lip in a patient with congenital hemangioma. This is a retrospective longitudinal study, with descriptive results, which was performed in a 32-year-old male patient to cover a lower lip lesion defect secondary to congenital hemangioma using buccinator myomucosal flap reconstruction. The buccinator myomucosal flap or jugal flap is considered one of the best local flaps for the reconstruction of the lower lip whatever the cause, due to its easy dissection and versatility due to the fact that it has a very high survival rate with minimal complications in the postoperative period. Our obtained results agree with the results already published by different authors, reaching the same conclusions; Although there are several techniques with local flaps for the reconstruction of the lower lip, the buccinator or jugal muscle flap is considered one of the main alternatives, since a functional and aesthetic lip can be achieved.

ABSTRACT

O objetivo desse trabalho é relatar um caso clínico de tratamento de úlcera traumática labial utilizando protetor bucal em paciente internado em uma Unidade de Terapia Intensiva. Paciente do sexo feminino diagnosticada com uma doença neurodegenerativa apresentou uma lesão de aspecto ulcerado, de aproximadamente 12 mm na mucosa do lábio inferior. O diagnóstico foi de úlcera traumática decorrente de espasmos musculares involuntários em face. O tratamento proposto foi instalação de protetor bucal confeccionado a partir de uma moldeira pré-fabricada de EVA (etil-vinil-acetato) borrachóide associado à medicação tópica a base de corticosteroide sobre a lesão. Após 5 dias foi observada cicatrização completa da úlcera, dispensando o uso do dispositivo. Nos dias seguintes de internação não foram observadas novas lesões. O protetor bucal instalado mostrou-se efetivo no afastamento do tecido traumatizado de novos traumas, protegeu os tecidos não lesionados e proporcionou qualidade de vida e segurança à paciente. Este relato reforça a importância da Odontologia na assistência do paciente crítico... (AU)

ABSTRACT

Cheilitis is a general term for various types of inflammatory diseases that occur on the lips. The etiology differs and the clinical manifestations and pathological features overlap, leading to difficulties in clinical diagnosis. Reasonable classification is conducive to the diagnosis of cheilitis. However, its classification is difficult because of its cha-racteristics. At present, scholars have proposed two different classification schemes, but a unified classification standard has not yet been established. We classified cheilitis based on its etiology, clinical manifestations, pathological characteristics, and relationship with systemic and special diseases on the basis of special medical reports and by combining clinical practice experience and summarizing previous cheilitis diagnosis and treatment literature. In accordance with this classification method, we proposed suggestions for the clinical diagnosis of cheilitis to provide a reference for the clinical diagnosis and treatment of complex cheilitis.

ABSTRACT

BACKGROUND@#Systemic and local factors may lead to disruption of craniofacial growth and development, causing an imbalance between the orofacial skeleton, muscle and soft tissue, dental occlusion, and the dental arch during growth periods. We aimed to reveal whether the prevalence of incompetent lip seal (ILS) varies with age and region, as well as to clarify the factors related to an ILS, in a national, large-scale epidemiological study.@*METHODS@#We surveyed 3399 children, from 3 to 12 years of age, visiting 66 pediatric dental clinics throughout Japan. For this survey, we employed a questionnaire consisting of 44 questions regarding daily health conditions and lifestyle habits. We evaluated the differences in ILS prevalence by age and region (using a Cochran-Armitage test for trend and a Kruskal-Wallis test), and the relationship between ILS and factors investigated in the questionnaire (using Spearman's rank correlation coefficient).@*RESULTS@#We observed that 30.7% of Japanese children exhibited an ILS and that the ILS rate increased with age (p < 0.001). There were no regional differences in the rate of ILS in Japanese children (p = 0.506). We revealed that 12 of 44 survey items exhibited a statistically significant correlation with ILS (p < 0.001), using Spearman's rank correlation coefficient. These items involved orofacial morphology, mouth breathing, and possibly, allergic rhinitis.@*CONCLUSION@#The rate of ILS seems to increase with age in children, throughout Japan. Therefore, this disorder may not self-correct during the growth periods in these children. Guidelines are required for pediatric dentists to recognize ILS among children aged 3-12 years.

ABSTRACT

Melkersson-Rosenthal syndrome (MRS) is a rare neuro-muco-cutaneous syndrome, which is characterized by recurrent orofacial swelling, recurrent facial paralysis and fissured tongue. It has a high prevalence in young adults. Up to now, the etiology of MRS is still not clear, it may related to infection, immune deficiency and hereditary factors. The pharmacological therapy and surgery are the main treatment. Corticosteroids seems to be the drug of choice for MRS patient, but the specific dosage and therapeutic effect have not yet been determined. Surgeries of lips provide excellent results in persistentlip edema MRS cases. This article reviews the research progress on MRS, focusing on its epidemiology, etiology, histopathological characteristics, clinical manifestations, classification, diagnostic criteria, differential diagnosis and treatment, to provide information for its early diagnosis and appropriate treatment.

ABSTRACT

ABSTRACT Purpose Verify the position of lips and tongue at rest in newborns with and without ankyloglossia. Methods Cross-sectional study, carried out with 130 newborns in University Hospital. Data collection was performed by the researcher and speech-language pathologists from the Hospital. Information on gestational age, sex, weight, height and days of life was collected. The position of the lips and tongue at rest was evaluated through visual inspection with the newborns asleep. After the newborns were awakened, Neonatal Screening of the validated Protocol for the evaluation of the lingual frenulum for infants was performed to detect the alteration of the lingual frenulum. The data obtained were described and submitted to statistical analysis using the Chi-Square test to verify the association between the position of the lips with the tongue and to compare the position of the lips and tongue with and without ankyloglossia. The Mann-Whitney test was used to verify the behavior of the variables the differed between newborns with and without ankyloglossia. The significance level of 5% was adopted. Results When comparing the data, a significant difference was found between: weight and height with and without ankyloglossia; position of lips and tongue. An association between the position of the tongue and lips with and without ankyloglossia was also found. Conclusion Newborns without alteration of the lingual frenulum have a tendency to remain with their lips closed and their tongue elevated during rest and newborns with ankyloglossia have a tendency to keep their lips parted and their tongue low during rest.


RESUMO Objetivo Verificar a posição de lábios e língua no repouso em recém-nascidos com e sem anquiloglossia. Método Estudo transversal, realizado com 130 recém-nascidos em um Hospital Universitário. A coleta de dados foi realizada pela pesquisadora e por fonoaudiólogas do Hospital. Foi coletado informações sobre idade gestacional, sexo, peso, altura, dias de vida dos recém-nascidos. Foi avaliada a posição dos lábios e língua no repouso, com os recém-nascidos adormecidos, por inspeção visual. Após os recém-nascidos serem despertos, foi realizada Triagem Neonatal do Protocolo validado de avaliação do frênulo da língua em bebês, para detecção da alteração do frênulo lingual. Os dados obtidos foram descritos e submetidos à análise estatística através do teste Qui-Quadrado, para verificar a associação entre posição dos lábios com a língua e para comparar posição de lábios e língua com e sem anquiloglossia. O teste de Mann-Whitney foi utilizado para verificar o comportamento das variáveis que diferiam entre recém-nascidos com e sem anquiloglossia. Foi adotado o nível de significância de 5%. Resultados Houve diferença significativa entre: peso e altura com e sem anquiloglossia; entre posição de lábios e língua. Encontrou-se também associação entre posição de língua e de lábios com e sem anquiloglossia. Conclusão Os recém-nascidos sem alteração de frênulo lingual têm a tendência de permanecerem com os lábios fechados e a língua elevada durante o repouso, e recém-nascidos com anquiloglossia, têm a tendência de manterem os lábios entreabertos e a língua baixa durante o repouso.

ABSTRACT

A análise da impressão labial, conhecida como queiloscopia, pode ser útil em casos específicos de investigação forense. Este trabalho experimental teve como objetivos principais investigar a precisão na análise dos tipos de sulcos labiais, da espessura labial e da localização da comissura labial e observar diferenças estatísticas entre a classificação labial e o sexo dos indivíduos. A amostra foi composta por 100 voluntários. Foi realizada a mensuração da espessura labial com paquímetro, análise visual da comissura labial e classificação dos sulcos labiais por meio de sua impressão, sendo testada a concordância intra- e inter-observador (três avaliadores) pela reavaliação de 30% da amostra. Os resultados mostraram que é possível realizar a classificação das análises labiais, sendo que o tipo de lábio mais frequente encontrado foi o tipo I (34,25%). Em relação à espessura, o tipo misto, e a comissura do tipo abaixada, foram as predominantes, com 66% e 59% respectivamente. Além disso, observou-se que não houve diferença estatística entre os indivíduos do sexo masculino e feminino nas classificações estudadas. Em relação à precisão ao fazer as classificações as técnicas utilizadas foram consideradas aplicáveis pelos pesquisadores, uma vez que a classificação foi possível e a concordância observada foi de forte a moderada, exceto em um dos quadrantes da classificação da impressão labial

ABSTRACT

Introdução: A queiloscopia pode ser definida como estudo, registro e classificação das cristas e sulcos localizados na superfície das mucosas labiais. Objetivos: Analisar as características queiloscópicas de universitários da região Sul do Brasil, bem como identificar possíveis variações entre os sexos dos participantes. Materiais e métodos: Foi realizado um estudo observacional, classificatório e transversal com uma amostra de conveniência composta por 50 universitários de Odontologia de uma instituição privada. Para a coleta das impressões labiais foi utilizado uma pequena quantidade de batom de coloração vermelha para cada participante, espalhada nos lábios com hastes flexíveis de algodão. Em seguida, os lábios foram pressionados em movimento de rolagem contra cartolina branca apoiada sobre uma placa de vidro. Após a obtenção da impressão labial, esta foi subdividida em oito subquadrantes e numerada em sentido horário, e cada tipo de sulco foi classificado segundo o sistema proposto por Suzuki e Tsuchihashi (1970). Os dados foram analisados estatisticamente com a utilização dos Testes Qui-Quadrado e Razão de Verossimilhança (p=0,05). Resultados: O sulco Tipo I ́ apresentou-se mais frequente (26,3%) seguido pelos Tipos I (24,3%) e II (20,5%). Segundo a variável sexo, o Tipo II (24,0%) e I (23,0%) obteve maior expressividade em homens, enquanto os sulcos I ́(31,5%) e I (25,5%) apresentaram-se prevalentes no sexo feminino. Conclusão: Os tipos de sulcos labiais mais encontrados foram o Tipo I', seguido pelo Tipo I no grupo total avaliado, sendo mais prevalentes os Tipos I´ e II, respectivamente para o sexo feminino e masculino. A queiloscopia não resultou em caracterizações com dimorfismos sexuais, e novos estudos se fazem necessários para sua utilização em casos que envolvam vestígios labiais em identificação humana.

ABSTRACT

Abstract The aim of this study was to perform a comparative analysis of podoplanin (PDPN) and Twist immunoexpressions in lower lip and oral tongue squamous cell carcinomas (LLSCC and OTSCC, respectively). PDPN and Twist immunoexpressions were semi-quantitatively evaluated by analyzing the invasion front, the compressive areas, the large islands and nests and dissociated cells of the chosen carcinomas. Their statistical associations and correlations with clinical-pathological characteristics were verified by the Mann-Whitney and Spearman's test. Twist expression was low in both carcinomas, with <25% labeling on the invasive front. Significant differences were observed for LLSCC (p=0.032) and OTSCC (p=0.025) regarding PDPN immunoexpression in relation to the worst invasion patterns determined by a histological malignancy gradation system. Statistically significant negative correlations between PDPN membrane expression and general (r=-0.356, p=0.024) and cytoplasmic Twist expressions (r=-0.336; p=0.034) in LLSCC were also observed. Twist and PDPN are suggested to be associated to a more aggressive invasion pattern in both LLSCC and OTSCC cases but not related to the different biological behaviors on these anatomical sites. Also, it was seen that PDPN membrane expression is inversely related to general and cytoplasmic Twist expression in LLSCC cases.


Resumo O objetivo deste estudo foi realizar uma análise comparativa das imunoexpressões de podoplanina (PDPN) e Twist em carcinomas de células escamosas de lábio inferior e língua oral (CCELI e CCELO, respectivamente). As imunoexpressões de PDPN e Twist foram avaliadas semi-quantitativamente através da análise do front invasivo, das áreas compressivas, das grandes ilhas e ninhos e das células dissociadas dos carcinomas escolhidos. Suas associações estatísticas e correlações com características clínico-patológicas foram verificadas pelos testes de Mann-Whitney e Spearman. A expressão de Twist foi baixa nos dois carcinomas, com marcação <25% no front invasivo. Diferenças significativas foram observadas para CCELI (p=0,032) e CCELO (p=0,025) em relação à imunoexpressão de PDPN em relação aos piores padrões de invasão determinados por um sistema de gradação histológica de malignidade. Também foram observadas correlações negativas estatisticamente significantes entre a expressão membranar de PDPN e as expressões geral (r=-0,356, p=0,024) e citoplasmática do Twist (r=-0,336; p=0,034) no CCELI. Sugere-se que o Twist e o PDPN estejam associados a um padrão de invasão mais agressivo nos casos de CCELI e CCELO, mas não relacionados aos diferentes comportamentos biológicos nesses sítios anatômicos. Também foi observado que a expressão membranar de PDPN está inversamente relacionada à expressão geral e citoplasmática de Twist em casos de CCELI.

Considerações finais: Os traumas por bicicleta podem ter graves consequências orofaciais. Constata-se a indispensável avaliação profissional quanto as características dos tecidos moles e dento-alveolares, possibilitando ao paciente o retorno estético e funcional... (AU)


Introduction: The face is the region of the most projected human body which leads to traumatic injuries with important sequelae. It performs aesthetic and functional functions such as facial expressions. Tissue reconstructions should be performed with the purpose of restoring the functionality, asymmetry and contour of the region. The characteristics of lesioned soft tissues should be considered, which should be reconstituted with the appearance closest to the lesion site. The aim of the present study is to report the reconstruction of the upper lip and the dental alveolus immediately after a cycling accident. Case report: Male patient, 26 years of age, normossemic, attended the emergency service of Buco-Maxillo-Facial Surgery and Traumatology due to a bicycle fall, which would have been caused by the fork breaking, which evolved with laceration in the lip superiority and in-alveolar fracture. A reconstruction of the upper lip and dental alveoli was performed. The patient evolved 45 days postoperatively with discrete scar and preserved function. Final considerations: Bicycle traumas can have serious orofacial consequences. It is necessary to evaluate the professional characteristics of the soft and dentoalveolar tissues, allowing the patient to return aesthetic and functional... (AU)

ABSTRACT

La armonía facial en ortodoncia está determinada por las relaciones morfológicas y proporcionales de la nariz, los labios y el mentón. Debido a que la nariz se encuentra en el centro de la cara, sirve junto con los labios y el mentón para caracterizar la apariencia facial, única para cada individuo. Junto con su función respiratoria, la configuración de la nariz, también, tiene un fuerte impacto en la estética facial general y, en gran medida, influye en el grado de convexidad del perfil. El objetivo de este trabajo fue determinar la relación entre el ángulo ANB y el ángulo nasolabial en pacientes con Clase I, II y III esqueletal, a través de trazados cefalométricos, en radiografías laterales de cráneo, con perfil facial, iniciales de un tratamiento de ortodoncia. Para esto, se midieron 200 radiografías laterales de cráneo de pacientes con dentición permanente de ambos sexos. Se hizo un análisis cuantitativo de los datos registrándolos con estadística descriptiva, y gráficos de barra y torta. Se utilizó el coeficiente de correlación de Pearson para determinar si las medidas de los ángulos mencionados, tenían una correlación estadísticamente significativa. Se determinó que los pacientes con normoclusión presentaron una correlación positiva con un ángulo nasolabial normal, los pacientes con mesioclusión presentaron una correlación negativa con un ángulo nasolabial obtuso, y los pacientes con una distoclusión presentaron correlación con un ángulo nasolabial normal(AU)


The facial harmony in orthodontics is determined by the morphological and proportional relations of nose, lips and chin. As the nose is in the center of the face, it serves together with lips and chin to characterize the facial appearance, unique to each individual. Along with its respiratory function, the nose configuration also has a strong impact on overall facial aesthetics and greatly influences the degree of convexity of the profile. The purpose of this paper was to determine the relation between the ANB angle and the nasolabial angle in patients with skeletal Class I, II and III, through cephalometric tracings, on lateral skull radiographs, with facial profile, that were initial of an orthodontic treatment. For this purpose, 200 lateral skull radiographs of patients with permanent dentition, of either sex, were measured. A quantitative analysis of the data was made, recording them through descriptive statistics, and bar graphs and pie charts. Pearson's correlation coefficient was used to determine whether the measurements of the mentioned angles had a statistically significant correlation. It was established that patients with normocclusion showed a positive correlation with a normal nasolabial angle, patients with mesiocclusion presented a negative correlation with an obtuse nasolabial angle and patients with distocclusion had correlation with a normal nasolabial angle(AU)

ABSTRACT

Hemangioma infantil (HI) é o tumor vascular mais comum e a neoplasia benigna mais frequente da infância, com maior incidência no sexo feminino e na população branca. Quase 60% dos casos ocorrem em cabeça e pescoço, sendo o tratamento ativo durante a fase proliferativa mais frequentemente indicado, em decorrência dos possíveis problemas funcionais e do potencial desfigurante. Relatamos um caso de paciente com hemangioma infantil involuído de ponta nasal e lábio superior, tratado de forma expectante durante a infância, submetida à correção da deformidade residual com técnicas de rinoplastia, associado à zetaplastia e lipoenxertia do lábio superior com bom resultado e satisfação do paciente.


Infantile hemangioma (IH) is the most common vascular tumor and the most frequent benign neoplasm in childhood, with the highest incidence in females and the white population. Almost 60% of cases occur in the head and neck, and active treatment during the proliferative phase is the most frequently indicated, due to possible functional problems and disfiguring potential. We report a case of a patient with involute infantile hemangioma of the nasal tip and upper lip, treated expectantly during childhood, submitted to residual deformity correction with rhinoplasty techniques, associated with zetaplasty and upper lip grafting with good results and patient satisfaction.
