Introduction: Childhood dental caries is a public health problem in Ecuador. Children aged 3-5 years with deciduous dental caries experience unpleasant symptoms such as pain while eating or sleeping, mood changes and school absenteeism, all of which has a negative impact on their quality of life. The key role played by parents in the oral care of their children is often determined by their educational level. Objective: Determine the impact of oral health on the quality of life of preschoolers aged under 5 years as evaluated by their parents or guardians and in relation to their educational level. Methods: A descriptive cross-sectional study was conducted of 382 parents and/or guardians of preschool children aged 3-5 years from four Ecuadorian provinces selected by convenience sampling, who gave their informed consent and answered the ECOHIS (Early Childhood Oral Health Impact Scale) survey, Spanish version, which assesses the relationship between oral health and quality of life among preschoolers. The surveys were identified with codes. The data collected were transferred onto Excel tables and analyzed with the free software R.V3.4.1 using likelihood ratios at 14.7 % equivalent to 95 % confidence intervals for proportions, as well as the chi-square statistical test. Results: The following significance levels were obtained: for pain as reported by children (p= 0.152), for difficulty when drinking (p= 0.003), eating (p= 0.03), smiling (p= 0.002), speaking (p= 0.09), and for economic impact associated to oral health problems (p= 0.003). Conclusions: An association was found between the educational level of parents and their perception of the influence of oral health upon the quality of life of their children.

Introducción: Las personas con trastorno del espectro autista tienen un mayor riesgo de presentar complicaciones dentales, debido a las características propias de la enfermedad. Objetivo: Describir el estado de salud bucal, hábitos de higiene y hábitos bucales de un grupo de niños, adolescentes y adultos chilenos con trastorno del espectro autista. Métodos: Se realizó un estudio descriptivo de 123 sujetos con trastorno del espectro autista. Se aplicó un cuestionario sobre información socio-demográfica, antecedentes dentales, hábitos de higiene bucal y hábitos bucales, y se realizó un examen odontológico a cada participante para determinar la experiencia y prevalencia de caries, la puntuación según el índice de higiene bucal simplificado y el índice gingival, así como la presencia de traumatismo dentario, paladar profundo/ojival, mordida abierta anterior y mordida cruzada anterior y posterior. Resultados: El 48 % de los sujetos con trastorno del espectro autista se cepillaba dos veces al día y el 68,0 % tenía un cepillado asistido. El 94,3 % presentaba hábitos bucales, de los cuales los más frecuentes eran el bruxismo con 57,7 % y la respiración bucal con 52,9 %. La prevalencia de caries fue de 33,3 %, el índice total de caries en dentición permanente de 1,1 ± 1,8 y el índice total de caries en dentición temporal y permanente de 2,6 ± 3,3. El índice de higiene bucal simplificado para los 123 sujetos fue de 1,30 ± 0,58. Conclusiones: La mayor parte de los sujetos tenían un cepillado asistido y lo realizaban dos veces al día. Los hábitos bucales más prevalentes fueron el bruxismo y la respiración bucal. En los 123 sujetos con trastorno del espectro autista se observó una baja prevalencia de caries, un índice total de caries en dentición permanente muy bajo y un índice de higiene bucal regular.

Introducción: El nivel de maduración dental como indicador del nivel de maduración general de acuerdo con el método de Demirjian, puede ser afectado por la altitud geográfica.Objetivo: Determinar la relación de las edades cronológica y dental según el método Demirjian en niños de dos localidades peruanas con diferente altitud.Métodos: Se realizó un estudio observacional, analítico, retrospectivo de corte transversal, que tuvo como muestra a 179 radiografías panorámicas de niños peruanos entre 6 y 12 años: 109 radiografías de niños de la ciudad de Lima y 70 radiografías de niños de la ciudad de Huancayo. Se determinó la edad dental según el método de Demirjian, luego se relacionó con la edad cronológica en cada paciente de las dos localidades; posteriormente se comparó las diferencias de las edades en las dos ciudades.Resultados: Se encontró correlación estadísticamente significativa entre la edad dental y la cronológica en ambos sexos de pacientes de la ciudad de Lima (p< 0,001); mientras que solo se encontró correlación estadísticamente significativa entre la edad dental y la edad cronológica en el sexo masculino en la ciudad de Huancayo (p< 0,001 para el sexo masculino y p= 0,740 para el femenino). La comparación de las diferencias entre edad cronológica y edad dental de los pacientes de las dos ciudades es no estadísticamente significativa (U de Mann-Whitney, p= 0,057).Conclusiones: No se encontró correlación significativa entre las edades dentales y cronológicas en el sexo femenino de los pacientes habitantes a mayor altitud y al comparar las diferencias, entre la edad cronológica y la edad dental según el método Demirjian, en los habitantes de las localidades peruanas no se encontró diferencia estadísticamente significativa.

Introduction: Hemophilia is a genetic disease scarcely found in dental practice. On occasion it presents as a dental emergency in face of which the professional should relate the general clinical manifestations of the disease to an appropriate semiological, paraclinical and genetic-molecular analysis to diagnose the condition and apply relevant therapies aimed at solving the patient's main concern as well as managing and controlling its complications.Objective: Describe the main general pathophysiological features and aspects of dental interest of hemophilia, as well as the diagnostic tools related to the condition from a clinical, paraclinical and genetic-molecular perspective.Methods: A bibliographic search was conducted in the databases Pubmed, Proquest, Scielo and Elsevier of papers published in English and Spanish in a period of 13 years (2005-2018), using the search terms "hemophilia A", "hemophilia B", "diagnostic criteria", "genetic", "molecular", "oral health", "clinical diagnosis". A total 50 papers were selected.Data analysis and integration: Studies have shown that hemophilia, a genetic systemic condition, may have oral manifestations and complications. This makes it important to dentists, since the disease should be diagnosed from a genetic-molecular point of view and managed in an interdisciplinary manner.Conclusions: Genetic-molecular diagnosis by geneticists implies involvement of hematologists and dentists in the management and control of the condition via interconsultation, when it comes to deciding on procedures for hemophilic patients.

Introduction: Giant cell central lesion is characteristic of the gnathic bones, being a non-odontogenic benign tumor. Classified as a predominantly slow grotwh, well-circumscribed and asymptomatic lesion usually diagnosed through routine examination or in some and more advanced cases once it begins to create some aesthetic-anatomical alteration or when the patient starts complaining of some located discomfort in the region. Objective: To present a clinical case of central giant cell lesion and its resolution involving surgical approach and second management, which includes homeopathy as a therapeutic proposal.Case presentation: central giant cell lesion located in the premaxilla region in a 4 years old female patient. After radiographic, tomographic and blood exams evaluation, followed by incisional biopsy and diagnostic, leading to surgical approach to remove the entire lesion by curettage with Carnoy’s solution application under general anesthesia. After appearance of radiopaque imaging in the proservation examinations, the non-invasive treatment by corticoid injection and homeopathy got started aiming the reduction of cicatricial tissue’s suggestive area and neoformation of the bone.Conclusions: approaches that are more conservative can be, in many cases, a plausible option that ends up ridding the patient of mutilating surgeries.

Introduction: Malocclusion is triggered by rupture of the balance between extraoral and intraoral forces as a result of an anomalous function. Such anomalous muscular functions are known as harmful oral habits. Objective: Update knowledge and analyze factors related to dental malocclusions, such as harmful oral habits in children, in terms of the frequency and duration of nutritive and non-nutritive sucking, mouth breathing and atypical tongue thrust. Methods: A bibliographic review was conducted of papers published in the last five years in the digital databases Pubmed, Lilacs, Ibecs and Cumed. The search terms used were malocclusion, habits, finger sucking, pacifiers, bottle feeding, tongue habit and mouth breathing in English, and maloclusión, hábitos, succión del dedo, chupete, biberones, hábitos linguales and respiración por la boca in Spanish. 65 papers were obtained, of which only 39 met the inclusion criteria. Data analysis and integration: 89.5 % of the papers corresponded to studies about non-nutritive sucking habits alone or in combination with other habits, whereas 10.5 % dealt with studies about mouth breathing children. Only 26.31 % of the studies selected took into account the variables duration and frequency of the habits. Nutritive sucking habits were found to be associated with overjet, posterior crossbite and distal step. A relationship was also found between a short breastfeeding period and the prevalence of non-nutritive sucking habits, with the presence of anterior open bite alongside the aforementioned malocclusions. Mouth breathing was related to class II, small retrognathic jaw and a decreased lower third of the face. Conclusions: Numerous studies have been conducted to determine the relationship between malocclusions and the duration of nutritive and non-nutritive sucking habits, without considering the frequency of such habits. On the other hand, the electronic databases consulted contain few studies about mouth breathing and atypical tongue thrust in children.

Introducción: Las retenciones dentarias afectan al 17 % de los pacientes a nivel mundial y están consideradas actualmente como un síndrome, en que los terceros molares ocupan el primer lugar y cuya extirpación quirúrgica deviene la intervención más comúnmente practicada por los cirujanos maxilofaciales. Objetivo: Describir las características anatomorradiográficas de los terceros molares, así como su posible relación con variables epidemiológicas de interés. Métodos: Se realizó un estudio observacional, descriptivo y transversal en escolares del Instituto Preuniversitario "Antonio Alomá Serrano", perteneciente al área de salud del Policlínico Docente Asistencial "José Martí" de Santiago de Cuba, durante el período comprendido desde mayo de 2016 hasta febrero de 2017. Se utilizaron radiografías panorámicas indicadas a estos pacientes, en las que se efectuaron el análisis y la clasificación. Resultados: La mayoría de los dientes se encontraban en clase I (52,6 %), clase C (51,9 %), posición C (82,2 %), verticales (47,7 %) y sin aproximación sinusal (89,5%). Además se observaron relaciones significativas entre la edad y el color de la piel con respecto al espacio retromolar y la inclinación dentaria de este grupo molar, y entre el sexo y la inclinación. Conclusiones: Los terceros molares son los dientes con mayor variabilidad en cuanto a posición e inclinación intraósea y en edades avanzadas se logra suficiente espacio retromolar y verticalización en la mayoría de ellos.

Introduction: Some types of cancer are often treated with chemotherapeutic drugs which indirectly affect the oral cavity, thus making the patient vulnerable to infections such as oral candidiasis. Oral infection by Candida albicans has been found to be fostered by oncological conditions, but other Candida species have not been sufficiently analyzed in such a context.Objective: Identify Candida spp. in the oral cavity of patients undergoing cancer chemotherapy.Methods: A descriptive cross-sectional study was conducted of 60 samples of an equal number of patients selected by convenience sampling at an Oncological Institute in Barranquilla, Colombia, following diagnostic clinical examination for oral candidiasis. Swab samples were taken from the infected surfaces to perform direct examination – Gram staining and Sabouraud dextrose agar culture with chloramphenicol incubated at 37ºC for 48 h and then cultured in CHROMagar® Candida medium – for identification of various species. Analysis was based on correlation and descriptive statistics.Results: Of the total patients evaluated 55% were female and aged over 60 years. Breast cancer prevailed with 30%. The chemotherapy applied in all cases was 5-fluorouracil combined with cyclophosphamide. Atrophic candidiasis of the tongue was the most common clinical type with 37%, followed by pseudomembranous candidiasis of the tongue with 33%. Of the samples examined, 90% contained some sort of Candida, growth of a single species and mixed cultures with more than one Candida species. C. albicans represented 13.3% and non-albicans spp. another 13.3%. None of the oncological diagnostic analyses had a statistically significant association to Candida species.Conclusions: The species C. albicans was the most commonly found in oral candidiasis among cancer patients, with a predominance of non-albicans Candida spp. (C. glabrata, C. tropicalis) mixed cultures, a fact not generally related to this condition.

Introdução: As lesões cervicais não cariosas são lesões dentárias, que apresentam etiologia multifatorial, sem o envolvimento de bactérias.Objetivo: Descrever as características clínicas, etiologia e tratamento das lesões cervicais não-cariosas.Métodos: Realizou-se uma revisão bibliográfica de estudos publicados nos últimos 5 anos (2014-2018) por meio da busca nas bases de dados: PubMED/Medline, Lilacs, Science Direct, SciELO (Scientific Eletronic Library) e Google Acadêmico. Para a pesquisa foram utilizados os seguintes descritores: “lesões cervicais não cariosas (non-carious cervical lesions)”, “abrasão dentária (dental abrasion)”, “erosão dentária (dental erosion)”, “abfração dentária (dental abfraction)” e “atrição dentária (dental atrittion). Após criteriosa filtragem, foram selecionados 26 artigos e 2 livros para inclusão no estudo.Análise e integração das informações: As lesões cervicais não cariosas comumente classificadas em: abrasão, abfração, erosão e atrição. Essas lesões podem apresentar diversas formas, apesar de serem incluídas em uma classe genérica de denominação. São lesões que causam a perda gradativa dos tecidos mineralizados dentários, podendo trazer inúmeras consequências ao dente acometido.Conclusão: Para um correto diagnóstico e decisão de tratamento, essas lesões devem ser vistas sob seu aspecto etiológico multifatorial. Diversas possibilidades terapêuticas podem ser utilizadas no tratamento dessas lesões sendo necessário que o clínico conheça os principais fatores etiológicos e características clínicas que as diferenciem.
