Perioperative administration of recombinant activated factor VII in a Glanzmann's thrombasthenia patient with platelet refractoriness: case report

Abstract Glanzmannʼs Trombasthenia (GT) is a genetic disorder, that develops with a tendency toward bleeding and is characterized by the absence or decrease in platelet aggregation. Surgical bleeding may be difficult to control. Platelet transfusion is the main treatment, albeit refractoriness can occur. We describe the case of a patient with GT and platelet refractoriness, who was submitted to radical prostatectomy and dental extraction. The perioperative treatment with apheresis platelet concentrate and activated recombinant factor seven allowed the procedures to be performed uneventfully. We discuss the complexity of the case and the treatment option.

Reasons of tooth mortality by continents in the last 20 years

Introduction: The reasons for tooth loss have been well defined for several centuries. However, systematic analysis of the causes of tooth loss in the first years of the present century would shed light on the current manifestation of this phenomenon. Objective: Determine the main causes of tooth mortality in the last 20 years. Methods: A systematic review was conducted using the Boolean search engines in PubMed, Web of Science, Scopus and SciELO bibliographic search platforms. The search was based on the following MeSH terms: cause, motive, mortality, extraction, dental extraction, loss, and combinations thereof. The articles included were in English or Spanish. Calibration was performed by the authors to evaluate the articles to be selected. Results: A total 593 articles were retrieved: 16 from Web of Science, 39 from Scopus, 531 from Pubmed and 1 from SciELO, of which 26 were included in the study. A predominance was found of articles published in English (80.8 percent). The main causes of tooth mortality dealt with were dental caries (92.30 percent) and periodontal disease (50.0 percent). Conclusions: The evidence obtained in the last 20 years is insufficient to determine the main reasons for dental extraction by continent. There is little availability of articles about areas from the most densely populated and developed countries in each continent. The articles included showed a predominance of dental caries and periodontal disease as the main reasons for dental extraction(AU)

Introducción: Las razones de la pérdida dentaria han sido bien definidas desde hace varios siglos. Sin embargo, sistematizar sobre las causas en los primeros años del presente siglo aportaría una visión de cómo se manifiestan en la actualidad. Objetivo: Determinar las principales causas de mortalidad dental en los últimos 20 años. Métodos: Se realizó una revisión sistemática utilizando los motores de búsqueda booleanos en la plataforma de búsqueda bibliográfica de PubMed, Web of Science, Scopus y SciELO. Las palabras clave utilizadas para la búsqueda fueron MesH: causa, motivo, mortalidad, extracción, extracción dental, pérdida y una combinación entre ellas. Se incluyeron artículos en español e inglés. Se realizó una calibración entre los autores para la evaluación de los artículos a seleccionar. Resultados: Como resultado de la búsqueda se obtuvieron 593 artículos, de los cuales 16 fueron de Web of Science, 39 de Scopus, 531 de Pubmed y 1 de SciELO. Los artículos incluidos en el estudio fueron 26. Predominaron las investigaciones publicadas en inglés (80,8 por ciento), que destacó entre los motivos de mortalidad dental estudiados, se encontró un predominio de caries dental (92,30 por ciento) y enfermedad periodontal (50,0 por ciento). Conclusiones: La evidencia obtenida en los últimos 20 años para determinar las principales razones de extracción dentaria por continentes es insuficiente y se observa la poca presencia de artículos en poblaciones de países con mayor desarrollado y número de habitantes de cada continente. Los artículos incluidos mostraron un predominio de la caries dental y la enfermedad periodontal como los principales motivos de extracción dentaria(AU)

Proporção de exodontia no estado de São Paulo e sua relação com a cobertura da Equipe de Saúde Bucal / Proportion of dental extraction in the state of São Paulo and its relation with the coverage of the Oral Health Team

Resumo Introdução O conhecimento dos fatores relacionados à perda dentária contribui para o planejamento das ações preventivas realizadas pelas Equipes de Saúde Bucal (ESBs). Objetivo Avaliar o indicador de proporção de exodontia nos municípios do estado de São Paulo e a sua relação com os indicadores socioeconômicos e cobertura das ESBs. Método Estudo ecológico com dados secundários dos 645 municípios do estado de São Paulo do ano de 2012. A variável dependente foi o percentual de exodontia mensurado pelo indicador de proporção de exodontia em relação aos procedimentos individuais realizados pelas ESBs, disponibilizado pelo Sistema de Informação da Atenção Básica. Foram considerados como variáveis independentes a cobertura populacional estimada pelas ESBs, o Produto Interno Bruto (PIB) dos municípios per capita, o Índice de Desenvolvimento Humano (IDH) e o Índice Paulista de Responsabilidade Social (IPRS). Foram aplicados modelos lineares generalizados, avaliados pelo p-valor do teste de Wald, AICC e grau de liberdade. Resultados Apresentaram maior proporção de extrações dentárias as cidades do estado de São Paulo com menor cobertura de ESBs (p < 0,0001), com menor valor de IDH (p < 0,0001) e com maior valor de IPRS (p = 0,0018). Conclusão A baixa cobertura de ESBs e as desigualdades socioeconômicas contribuem para aumentar as extrações dentárias no estado de São Paulo.

Abstract Background Knowledge about factors associated with tooth loss contributes to the planning of preventive actions carried out by Oral Health Teams (OHT). Objective To evaluate the proportion of dental extraction indicator in the cities of the state of São Paulo, Brazil, and its relationship with socioeconomic indicators and coverage of the OHT. Method Ecological study using secondary data from 654 municipalities in the state of São Paulo conducted in 2012. The dependent variable was the percentage of dental extraction measured by the proportion of this indicator in relation to individual procedures performed by the OHT provided by the Primary Health Care (PHC) Information System. The population coverage by the OHT, the per capita Gross Domestic Product (GDP), the Human Development Index (HDI), and the São Paulo Social Responsibility Index (IPRS) of the municipalities were evaluated as independent variables. Generalized linear models, formulated by the Wald test p-value, Corrected Akaike Information Criterion (AICc), and degree of freedom, were applied. Results Higher proportions of dental extraction were found in the municipalities with lower coverage by OHT (p<0.0001), lower HDI value (p<0.0001), and higher IPRS value (p=0. 0018). Conclusion Low coverage by OHT and socioeconomic inequalities contribute to increased proportion of dental extractions in the state of São Paulo.

Esfuerzos generados en la ATM en maloclusión clase II, tratada con exodoncias de premolares y ortodoncia: análisis mediante el método de elementos finitos / Strain generated in the TMJ with class II malocclusions, treated with extraction of premolars and orthodontics: analysis with the finite element method

RESUMEN Introducción: la exodoncia de premolares es una alternativa para el tratamiento de la maloclusión clase II. Un cambio en la biomecánica puede generar alteraciones en la Articulación Temporomandibular (ATM) lo que produce mayor desgaste dental y aparición de patologías articulares. El objetivo fue analizar mediante el método de elementos finitos la concentración de esfuerzos en la ATM, en maloclusión clase II, tratados con exodoncia de premolares y Ortodoncia. Métodos: dos modelos de simulación en 3D cada uno con estructuras óseas de los 2 maxilares, dentición completa y disco en la ATM. Uno corresponde al paciente sin recidiva (SR) tratado con exodoncia de primeros premolares y ortodoncia, donde se mantiene la estabilidad dental clase I. El otro modelo con recidiva (CR) tratada con exodoncia de primeros premolares y ortodoncia, aumento de overjet y overbite y clase II canina; la carga se aplicó sobre la rama mandibular. Resultados: con una carga de 900N los esfuerzos se triplicaron en todas las estructuras de los dos modelos al ser comparados con una carga de 300N; sin embargo, se dieron diferencias considerables en el modelo CR entre las cavidades glenoideas, a 300N de 19.9 MPa y a 900N de 59.3 MPa. La mayor concentración del disco se da en la parte lateral. Conclusiones: dada la asimetría en las estructuras de la ATM, los esfuerzos y la concentración de tensiones difieren entre el lado derecho e izquierdo en los dos modelos.

Abstract Introduction: premolar extraction is an alternative for the treatment of class II malocclusion. A change in biomechanics can generate alterations in the Temporomandibular Joint (TMJ), which produces greater dental wear and the appearance of joint dysfunctions. The objective was to assess the effort concentration in the TMJ by means of finite element analysis in class II malocclusions treated with premolar extraction and orthodontics. Method: two 3D simulation models each with bone structures of the 2 jaws, complete dentition and disc in the TMJ. One corresponds to the patient without recurrence (WR) treated with extraction of first premolars and orthodontics, where class I dental stability is maintained. The other model with recurrence (R) treated with extraction of first premolars and orthodontics, increased overjet and overbite and canine class II; the load was applied to the mandibular ramus. Results: loads of 900N triplicated on all structures compared to 300N in both models. However, there were considerable differences between the left and right glenoid cavities in the WR model, at 300N of 19.9 MPa and 900N at 59.3 MPa. Most tensions of the disc occur in the lateral part. Conclusions: due to the asymmetry in the TMJ structures, the stresses and stress concentration differ between the right and left sides in the two models.

Avaliação do comportamento odontológico infantil durante procedimentos de profilaxia e exodontia / Evaluation of children's dental behavior during prophylaxis and extraction procedures

Objetivo: Avaliar o comportamento infantil durante os tratamentos odontológicos de profilaxia e de exodontia. Métodos: Este estudo transversal contou com 58 crianças, entre 6 e 9 anos de idade. Dentre essas, 29 crianças foram submetidas ao procedimento de exodontia e 29 ao procedimento de profilaxia. O comportamento infantil frente ao tratamento odontológico proposto foi avaliado por um cirurgião-dentista treinado através da versão brasileira e validada da Escala Comportamental de Venham (Venham's Behavior Rating Scale (BvVBRS). Avaliou-se também a ansiedade infantil prévia ao tratamento odontológico através da Venham Picture Test modificada (VPTm). A condição bucal foi avaliada pelo índice CPO-D e ceo-d, por pesquisador previamente calibrado (Kappa > 0,7). Os pais/responsáveis responderam a um questionário socioeconômico e questões relacionadas a experiência odontológica prévia das crianças. Realizou-se análise descritiva e teste Qui-quadrado com nível de significância de 5%. Resultados: Em relação ao comportamento o grupo submetido à profilaxia apresentou 100% das crianças com um comportamento positivo, enquanto no grupo submetido à exodontia houve 75,9% das crianças com comportamento positivo (p = 0,010). Idade, gênero e presença de ansiedade prévia aos procedimentos não tiveram relação estatisticamente significante com o comportamento infantil. A presença de cárie na dentição decídua esteve associada ao comportamento negativo durante os procedimentos odontológicos (p = 0,013). Conclusão: Foi observado que durante o procedimento de profilaxia os pacientes demonstraram um comportamento mais colaborador quando comparado ao procedimento de exodontia.

Aim:To investigate the behavior of children during dental treatments of prophylaxis and dental extraction. Methods: Fifty-eight children, 6 to 9 years of age, and their caregivers participated of this cross-sectional study. Of these, 29 children underwent prophylaxis and 29 dental extraction. Child behavior was assessed through the Brazilian version of the Venham's Behavior Rating Scale (BvVBRS), and dental anxiety was measured by the Venham Picture Test modified (VPTm). Clinical examination was performed by a calibrated examiner (Kappa > 0.7), using the decay, missing, filled index for primary and permanent dentition dmft/DMFT index. The caregivers answered a socioeconomic questionnaire and questions related to the previous dental experience of the children. Descriptive data analysis and Chi-square test were performed, with a significance level of 5%. Results:Regarding behavior, the prophylaxis group presented 100% of children with a positive behavior, while the extraction group contained 75.9% of children with positive behavior, and this difference was statistically significant (p = 0.010). Age, gender, and presence of anxiety prior to the procedures had no statistically significant relationship to the presented child behavior. The presence of caries in the deciduous dentition was associated with child behavior during dental procedures (p = 0.013). Conclusion: It was observed that the type of procedure interfered directly in the negative behavior of the children, with a difference in cooperation with invasive (dental extraction) and non-invasive (prophylaxis) procedures.

Assessment of Patients Undergoing Therapeutic Dental Extractions for Orthodontic Purposes

ABSTRACTBackground: Since the early days of orthodontics the need fortooth extractions in certain orthodontic situations has beendiscussed. Hence; under the light of above mentioned data, thepresent study was undertaken for assessing the patientsundergoing therapeutic dental extractions for orthodonticpurposes.Materials & Methods: A total of 85 patients who underwentorthodontic treatment were included in the present study.Complete demographic and clinical details of all the patientswere obtained. Clinical examination of all the patients wascarried out. Classification of the patients was also done on thebasis of type of angle’s classification. Frequency of dentalextraction was recorded. All the results were recorded inMicrosoft excel sheet and was analysed by SPSS software.Results: The overall frequency of therapeutic dental extractionwas 49.41 percent.

Comparison of efficacy of 0.75% ropivacaine and 2% lidocaine with 1:200,000 adrenaline in pain control in extraction of mandibular posterior teeth: A double-blind study

Two percent lidocaine hydrochloride is the gold standard for dental anesthesia against which newer local anesthetic agents may be compared. 0.75% ropivacaine is a newer, long-acting amide local anesthetic agent with inherent vasoconstriction property. Aim: This study aims to compare the efficacy of 0.75% ropivacaine and 2% lidocaine hydrochloride with 1:200,000 adrenaline in pain control in extraction of mandibular posterior teeth. Settings and Design: This is a prospective, double-blind, and split-mouth study. Subjects and Methods: Twenty patients were divided into two groups according to the right and left sides of patient – side A and side B. The side, where 0.75% ropivacaine was to be administered, was randomly selected by flip coin method. Then, the pterygomandibular and long buccal nerve blocks were administered with 0.75% ropivacaine and necessary dental extraction was performed. After 1 week, the same procedure was repeated using 2% lidocaine hydrochloride with 1:200,000 adrenaline. The parameters assessed were pain on injection, onset of anesthesia, pain during the extraction, and duration of anesthesia. Statistical Analysis Used: The nonparametric data were assessed by Mann Whitney “U” test. Results: The mean onset of action for solution A was 7.15 ± 4.934 min and for solution B was 9.75±5.128 min. This was statistically significant. The mean duration of action, pain on injection, and pain during extraction were not significant. Conclusion: This study clearly states that there is no clear advantage of using 0.75% ropivacaine in pterygomandibular nerve block over the gold standard. However, more clinical studies with larger sample size are necessary.

Oral health and socioeconomic indicators of adolescents living in a region of extreme poverty / Salud bucal e indicadores socioeconómicos de adolescentes residentes en una región de extrema pobreza

ABSTRACT. Introduction: Adolescence is a stage of life in which future hygiene habits are consolidated and is also a period of multiple discoveries and changes in human beings' life. As teenagers go through so many different new emotions, they often leave their health unattended, and thus are at greater risk of suffering oral diseases, which often affect this population early and are treated in late stages, resulting in tooth loss. The aim of this study was to evaluate the oral health profile of adolescents living in a region of extreme poverty. Methods: a cross-sectional analytical study assessing data from 205 adolescents living in the Augusta Meneguine district in the city of Viamão, Rio Grande do Sul, Brazil. Results: The average tooth loss was one tooth per teenager. The Student t-test (p ≤ 0.05) showed no significant differences by sex (p = 0.158). Adolescents whose families had a monthly income of up to one minimum wage had a higher average score of tooth loss, compared to those from families of higher monthly income, but this difference was not significant (p = 0.341). No significant differences were observed between lost teeth and sugar consumption (p = 0.869), nor in relation to the average number of cavities among adolescents with oral hygiene supervision (p = 0.631). Conclusions: This study helped identify poor oral health conditions and low socioeconomic levels among adolescents with low income and education levels, leading them to have high rates of visible plaque, gingival bleeding, caries, and tooth loss.

RESUMEN. Introducción: la adolescencia es la fase de la vida en la que se consolidan hábitos futuros de higiene, y es a su vez un periodo de múltiples descubrimientos y cambios en la vida del ser humano. Debido a la gran cantidad de nuevas emociones que se presentan, muchas veces los adolescentes acaban dejando su salud en segundo plano, lo que causa una mayor probabilidad de sufrir enfermedades bucales, que muchas veces atacan de manera precoz a esta población y son tratadas en fases tardías, dando como resultado pérdidas dentarias. El objetivo del presente estudio consistió en evaluar el perfil de salud bucal de adolescentes que viven en una región de extrema pobreza. Métodos: se trata de un estudio transversal y analítico, en el cual fueron analizados datos de 205 adolescentes residentes en el barrio Augusta Meneguine, localizado en la ciudad de Viamão, Rio Grande do Sul, Brasil. Resultados: el promedio de dientes perdidos fue de un diente por adolescente. La prueba t de Student (p ≤ 0,05) no mostró diferencias significativas por sexo (p = 0,158). Los adolescentes cuya familia contaba con un ingreso mensual de hasta un salario mínimo presentaron un valor promedio mayor de dientes perdidos, en comparación con los de familias de ingresos mensuales mayores, pero esta no fue una diferencia significativa (p = 0,341). Tampoco se observaron diferencias significativas entre los dientes perdidos y el consumo de azúcar (p = 0,869), ni en relación con el número promedio de caries entre los adolescentes que recibieron una supervisión de higiene bucal (p = 0,631). Conclusiones: el presente estudio permitió identificar un perfil carente de salud bucal y nivel socioeconómico de los adolescentes de bajos ingresos y niveles de educación, por lo que presentan altos índices de placa visible, sangrado gingival, caries y pérdidas dentarias.

Cierre de comunicación oroantral mediante el uso de membrana de plasma: revisión de la literatura y reporte de un caso clínico / Closure of oroantral communication using a plasma membrane: review of the literature and report of a clinical case

Una comunicación oroantral es el espacio creado entre el seno maxilar y la cavidad oral, si ésta no es tratada a tiempo puede desencadenar una fístula e inclusive la presencia de sinusitis crónica. La comunicación oroantral es una de las complicaciones con mayor prevalencia que puede presentarse durante los procedimientos quirúrgicos cercanos a la zona donde se vea involucrado el seno maxilar. Con mayor incidencia encontramos los primeros molares, seguidos de los segundos molares y por último los terceros molares. El manejo convencional de una comunicación oroantral va desde su cierre espontáneo hasta el manejo quirúrgico; esto dependerá del tamaño de la lesión y el tiempo transcurrido de ésta. El caso clínico se trata de un paciente de 42 años de edad con antecedente de extracción del O.D. 16 por facultativo particular, desarrollando posteriormente un cuadro de sinusitis, por lo que acude al Servicio de Urgencias del Hospital Regional 1o de Octubre, I.S.S.S.T.E. en la CDMX, siendo valorado por nuestro servicio, donde se observa una comunicación franca entre la cavidad bucal y el seno maxilar, realizándose cierre de la misma con una membrana de plasma rico en factores de crecimiento plaquetario (AU)

Oroantral communication is the space created between the maxillary sinus and the oral cavity, if the communication is not treated on time, it would progress to oroantral fi stula or chronic sinus disease. An oroantral communication is the most common complication during surgical procedures closer to the maxillary sinus. With greater incidence we found sites of upper fi rst molar, followed by the second molar and fi nally third molars. The conventional handling of an oroantral communication goes between spontaneously closure or surgical closure management, it will depend in the size of the lesion and the time elapsed. The present article shows a clinical case, is a male patient of 42 years old with a previous extraction of tooth 16, by a private doctor, later developing a picture of sinusitis. Then he goes to the emergency department of the Hospital 1o of October, ISSSTE in the CDMX, being evaluated by our service, where there is a frank communication between the oral cavity and the maxillary sinus, closing it with a plasma membrane rich in growth factors (AU)

Con el proceder realizado se logró la recuperación estética de los pacientes, así como la reinserción en las actividades sociales y laborales, evitando así las afectaciones psíquicas que suelen aparecer

The case reports of 3 adults with extracted teeth are presented. They were assisted in the dental prosthesis service of 30 de Noviembre Teaching Polyclinic in Santiago de Cuba to whom immediate prothesis were placed as the only solution due to the oral deterioration that presented. With this procedure the cosmetics of the patients was recovered and their reintegration to the social and labor activities was achieved, with which the psychic disorders that usually appear were avoided

Overdentures mandibulares sobre implantes imediatos não esplintados, em carga imediata: acompanhamento de 36 meses / Mandibular overdentures on implants immediately implanted, immediate load: 36 month follow-up

Objetivo: Relatar a taxa de sobrevivência de implantes imediatos suportando overdentures mandibulares, em carga imediata, e o índice de sucesso dos tratamentos acompanhados por 36 meses. Métodos: Os implantes foram instalados em um projeto de extensão universitária que se propõe a reabilitar pacientes de baixa renda, com dentição seriamente comprometida. Quarenta e dois pacientes foram selecionados para o estudo. Em três casos, não se alcançou travamento primário compatível com o procedimento de carga imediata sobre implantes. Nesses pacientes, as próteses foram capturadas de forma convencional, após o período de osseointegração. Trinta e nove pacientes receberam o tratamento proposto. Três deles sofreram perda precoce de um dos implantes, todos ainda no primeiro mês após os procedimentos. Os implantes perdidos foram, posteriormente, substituídos e recapturados após três meses. Trinta e seis pacientes completaram o período de osseointegração sem apresentar perdas. Os pacientes passaram, então, a ser avaliados semestralmente, sendo que 25 completaram o estudo. Onze pacientes não compareceram às consultas de reavaliação por motivos variados. Resultados: A taxa de sobrevivência, até o final do período de osseointegração foi de 96,15%, isso é, 3 implantes perdidos em 78 imediatamente carregados. O índice de sucesso dos tratamentos acompanhados por 36 meses foi de 100%, uma vez que não foi observada nenhuma perda adicional de implantes. Conclusão: A reabilitação oral de pacientes que perderam todos os seus dentes mandibulares, por meio de overdentures sobre implantes imediatos não esplintados, em carga imediata, utilizando-se o sistema bola, mostrou-se muito satisfatório, com alta taxa de sobrevivência dos implantes, e alto índice de sucesso dos tratamentos acompanhados por 36 meses. O projeto de extensão tem observado resultados clínicos, tanto estéticos quanto funcionais, altamente satisfatórios, proporcionando uma melhora acentuada na autoestima e na qualidade de vida da população assistida.

Aim:This study aimed to report the survival rate of immediate implants supporting mandibular overdentures, which have been immediately loaded, and the success rate of the treatments followed up for 36 months. Methods: The implants were installed in a university extension project that seeks to rehabilitate low-income patients with seriously compromised dentitions. Forty-two patients were selected for the study. In three cases, the primary stability proved to be incompatible with the immediate loading procedure on implants. Thus, in these cases prostheses were captured conventionally after the period of osseointegration. Thirtynine patients received the proposed treatment. Three of them suffered an early loss of one of the implants, all in the first month after the procedures. The lost implants were replaced and recaptured after three months. Thirty-six patients completed the period of osseointegration without implant loss. The patients were evaluated every six months, and twenty-five patients completed the study. Eleven patients did not take part in the follow-up sessions for various reasons. Results: The survival rate until the end of the period of osseointegration was 96.15%, in other words, within the 78 immediately loaded implants, three were lost. The success rate of treatments followed up for 36 months was 100%, without additional loss of implants. Conclusion: The oral rehabilitation of patients using overdentures on immediate implants with immediate loading, using the ball system, proved to be very satisfactory, with a high survival rate of the implants, and high success rates of treatments followed up for 36 months.

Consulta por extracción dental en niños nicaragüenses: una aproximación a las necesidades de atención bucal

Objetivo: Identificar los factores asociados a las visitas al dentista por motivo de extracción dental en niños nicaragüenses. Material y Métodos: Se realizó un estudio transversal en una muestra de escolares de 6 a 12 años de edad. Se incluyeron 1400 niños de escuelas públicas, a cuyos padres/tutores se les aplicó un cuestionario para determinar una serie de variables sociodemográficas, socioeconómicas y dentales. La variable dependiente fue la visita al dentista por extracción dental (VDED), la cual fue categorizada como: 0=Sin visita al dentista, 1= VDED, pero no en el último año, 2= VDED en el último año. En el análisis estadístico se emplearon pruebas estadísticas no paramétricas. Resultados: El promedio de edad fue de 9.00±2.00 años y las mujeres representaron el 49.9%. Del total de la muestra, 21.6% acudieron al dentista por extracción dental, de los cuales 9.8% lo hicieron hace más de un año y 11.8% durante al año pasado previo a la encuesta. Las variables que mostraron diferencias significativas (p<0.05) en el análisis estadístico de las VDED fueron la edad, la edad de la madre, y la posición socioeconómica. Conclusiones: Uno de cada cinco niños tuvo VDED. Las visitas al dentista por extracciones dentales podrían utilizarse como un indicador del estado de salud bucal de la población, ya que son una aproximación a las necesidades de salud que presentan.

Objective: To identify factors associated with visits to the dentist for dental extraction in Nicaraguan children. Materials and Methods: This was a cross-sectional study that was carried out in a sample of schoolchildren from 6 to 12 years of age. We included 1400 children from public schools, whose parents / guardians were given a questionnaire to determine a series of sociodemographic, socioeconomic and dental variables. The dependent variable was defined as a dental visit for dental extraction (VDED), which was categorized as: 0 = No visit to the dentist, 1 = VDED, but not in the last year, 2 = VDED in the last year. For statistical analysis, nonparametric statistical tests were used. Results: The average age was 9.00 ± 2.00 years, 49.9% of the total were females. Of the total sample, 21.6% went to the dentist for a dental extraction, of which 9.8% did so more than a year ago and 11.8% had gone during the year prior to the survey. The variables that showed significant differences (p <0.05) in the statistical analysis of the VDED were age of the patient, the age of the mother, and the socioeconomic status. Conclusions: One in five children had VDED. Visits to the dentist for dental extractions could be used as an indicator of the oral health status of the population, since they are an approximation the other health needs present in the population.

Evaluation of 1211 third molars positions according to the Classification of Winter, Pell & Gregory / Evaluación de posiciones de 1211 terceros molares acorde a la Clasificación de Winter, Pell & Gregory

Panoramic radiographs are important for the evaluation and classification of the third molars position, allowing the diagnosis and planning of extraction. The objective of this study is to evaluate upper and lower third molars positions in panoramic radiographs with the classification methods proposed by Pell and Gregory (1933) and Winter (1926) and the subsequent comparison of results with other authors. Panoramic radiographs of 310 patients were analyzed, 197 female and 113 male, totaling 1,211 third molars. In relation to the upper third molars, the most prevalent positions were: angle compared to the long axis of the second molar of Distoangular form (53.23 %) and the depth of impaction as Class C (48.25 %). In the lower third molars, the most prevalent positions were: angle to the long axis of the second molar in Mesioangular classification (52.96 %), the depth of impaction was B (46.54 %) and the tooth relationship with the mandibular ramus was identified as class I (55.26 %). These results provide information that can be utilized in predicting third molar development in terms of impaction or eruption, assisting dental surgeons in making decisions regarding surgical planning and treatment.

Las radiografías panorámicas son importantes para la evaluación y clasificación de la posición de los terceros molares, lo que permite el diagnóstico y la planificación de la extracción. El objetivo de este estudio fue evaluar terceros molares superiores e inferiores y posiciones en las radiografías panorámicas con los métodos de clasificación propuestas por Pell & Gregory, y Winter y la posterior comparación de los resultados con otros autores. Se analizaron las radiografías panorámicas de 310 pacientes, 197 mujeres y 113 hombres, con un total de 1.211 terceros molares. En relación con los terceros molares superiores, las posiciones más prevalentes fueron: ángulo con respecto al eje longitudinal del segundo molar de forma distoangular (53,23 %) y la profundidad de la impactación como Clase C (48,25 %). En los terceros molares inferiores, las posiciones más prevalentes fueron: ángulo con respecto al eje longitudinal del segundo molar en la clasificación mesioangular (52,96 %), la profundidad de impactación fue de B (46,54 %) y la relación de los dientes con la rama mandibular fue identificado como Clase I (55,26 %). Estos resultados proporcionan información que puede ser utilizada para predecir el desarrollo del tercer molar en términos de compactación o erupción, ayudando a los cirujanos dentistas en la toma de decisiones respecto a la planificación y el tratamiento quirúrgico.

Frictionless segmented mechanics for controlled space closure

ABSTRACT Extraction spaces may be needed to achieve specific orthodontic goals of positioning the dentition in harmony with the craniofacial complex. However, the fundamental reality that determines the occlusion final position is the control exerted by the orthodontist while closing the extraction spaces. A specific treatment objective may require the posterior teeth to remain in a constant position anteroposteriorly as well as vertically, while the anterior teeth occupy the entire extraction site. Another treatment objective may require the opposite, or any number of intentional alternatives of extraction site closure. The present case report describes a simple controlled segmented mechanic system that permitted definable and predictable force systems to be applied and allowed to predict the treatment outcome with confidence. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) in partial fulfillment of the requirements for Diplomate certification.

RESUMO Os espaços gerados pelas extrações de pré-molares podem ser necessários para que objetivos ortodônticos específicos sejam alcançados dentro do complexo craniofacial. No entanto, a realidade fundamental que determina a posição final da oclusão é o controle biomecânico exercido pelo ortodontista no fechamento dos espaços das extrações. Um objetivo específico do tratamento pode exigir que os dentes posteriores permaneçam estáveis em uma posição sagital e vertical, enquanto os dentes anteriores são retraídos e ocupam todo o espaço da extração. Outro objetivo de tratamento pode exigir o inverso, ou quaisquer alternativas intencionais de fechamento de espaços de extração. O presente relato de caso descreve um sistema simples de mecânica segmentada que permite, de maneira controlada, que sistemas com forças definidas e previsíveis sejam aplicados, permitindo também predizer o resultado do tratamento com segurança. Esse caso foi apresentado ao Board Brasileiro de Ortodontia e Ortopedia Facial (BBO), em cumprimento parcial dos requisitos para certificação.

Tratamiento de las discrepancias dentomaxilares en paciente clase II esqueletal. reporte de caso / Treatment of discrepancies dento-maxillary in patient class II skeletal. case report

La clase II esqueletal representa uno de los grandes desafíos a tratar por parte del Ortodoncista. Ésta se presenta cuando existe una discrepancia entre el maxilar y mandíbula, es decir puede haber un crecimiento excesivo del maxilar superior acompañado de una retrusión de la mandíbula. Esto provoca alteraciones tanto esqueléticas como dentarias, presentando apiñamientos, incompetencia labial o perfil convexo, pudiendo ser el tratamiento estrictamente ortodóntico o en ciertos casos requerir de cirugías máxilo faciales. El objetivo de esta investigación fue mejorar el perfil del paciente, conseguir Clase I molar y canina, corregir la incompetencia labial y mejorar la oclusión dental. El plan de tratamiento incluyó la extracción dental de primeros premolares superiores e inferiores y gracias a la aplicación de la técnica ROTH mediante el uso de cadenas elásticas y arcos de retracción se pudo cumplir el objetivo inicial, mejorando la estética y la función de las estructuras dento faciales.

Class II skeletal is one of the major challenges to be treated by the orthodontist. This occurs when there is a discrepancy between the maxilla and mandible, ie may have an overgrowth of the maxilla accompanied by a retrusion of the mandible. This causes both skeletal and dental alterations, presenting crowding, labial incompetence or convex profile and may be strictly orthodontic treatment or in certain cases require maxillo facial surgeries. The objective of this research was to improve the patient's profile, achieving Class I molar and canine, correct lip incompetence and improve occlusion. The treatment plan included tooth extraction first upper and lower premolars and thanks to the implementation of the ROTH technique using elastic chains and arches retraction could meet the initial objective,improving the aesthetics and function of the dento structures facial.

Osteonecrosis mandibular relacionada con medicamentos: conceptos teóricos y prácticos actuales para el odontólogo general

La osteonecrosis mandibular relacionada con medicamentos (ONMRM), es un síndrome asociado al uso de fármacos antirresortivos (bifosfonatos), inhibidores de ligando RANK-L y de angiogénesis, administrados para el tratamiento de enfermedades como cáncer y osteoporosis. Objetivos: actualizar contenidos respecto a etiopatogenia y tratamientos de ONMRM, enfatizando el rol del factor "infección", y en la perspectiva de que el tratamiento, pueda ser implementado por el odontólogo general. Materiales y métodos: se realiza un scoping review mediante acceso a las bases de datos MEDLINE (Pubmed) y Cochrane library, de artículos publicados desde el año 2010 en adelante, en inglés y castellano, empleando palabras claves incluidas en los medical subject headings (MeSH). Conclusiones: La evidencia recogida demuestra que, teniendo en cuenta los factores de riesgo individuales, no existen en general contraindicaciones para llevar a cabo exodoncias, bajo específicos protocolos quirúrgicos, en pacientes con terapias antiresortivas o antiangiogénicas, ya que al parecer, el origen de la ONMRM se asocia a contaminación por biofilm, más que al uso o efecto de estos fármacos. En el caso del tratamiento de una ONMRM ya instalada, las terapias quirúrgicas resultan ser más eficaces que las paliativas en la remisión del cuadro.

Medication-related osteonecrosis of the jaw (MRONJ) is a syndrome associated to the use of antiresorptive therapy (bisphosphonates), RANK-ligand inhibitors and angiogenesis inhibitors drugs, used for the treatment of cancer and osteoporosis among other diseases. Purpose: Update the knowledge on its etiopathogenesis emphasizing the role of infection, and in doing so, look for treatments that can be carried out by general practitioners. Materials and methods: A scoping review is performed through Medline (Pubmed) and Cochrane databases, of articles published from to 2010, in English and Spanish, including MeSH keywords such as "osteonecrosis of the jaw; "antiresorptive drug"; "bisphosphonates"; "Denosumab"; "surgical wound infection"; "dental extraction". Conclusions: The current evidence demonstrate that, taking into account individual risk factors, teeth extractions can be harmless performed in patients under antiresorptive or antiangiogenic interetherapies because the origin of MRONJ appears to be more related to biofilm contamination than with the use or effects of any specific drug. Once MRONJ is installed, surgical therapies prove to be more effective in the treatment and remission of these lesions.

Estudio retrospectivo de una población de pacientes sometidos a exodoncias en la Cátedra de Cirugía y Traumatología Bucomaxilofacial I de la Facultad de Odontología de la Universidad de Buenos Aires, en el período entre enero 2012 - mayo 2014 / A retrospective study on a patient population undergoing tooth extraction at the Department of Oral and Maxillofacial Surgery I, School of Dentistry, University of Buenos Aires, over a January 2012 - May 2014 period

La extracción dentaria es una de las prácticas odontológicas realizadas con mayor frecuencia, pero a corto plazo los pacientes necesitan rehabilitaciones orales para optimizar el funcionamiento del sistema estomatognático. Dado que conocer las características de la población que demanda exodoncias puede contribuir a elaborar estrategias para limitar la pérdida de piezas dentarias, nos propusimos 1) registrar las características de la población que demanda exodoncias; 2) identificar las piezas dentarias extraídas; 3) registrar las causas de exodoncia; 4) identificar patologías bucales durante la consulta para una exodoncia. Para llevarlo a cabo se seleccionaron aleatoriamente 2000 historias clínicas de pacientes que concurrieron a la Cátedra de Cirugía y Traumatología Buco Maxilofacial I de la Facultad de Odontología de la Universidad de Buenos Aires (FOUBA) y se realizaron exodoncias con anestesia local entre enero de 2012 y mayo de 2014...
