Introducción: El presente artículo ahonda en las teorías más aceptadas sobre el proceso de erupción dental en la literatura de hoy en día y, desde este enfoque, expone el caso clínico de una paciente de 12 años de edad que presentaba retención de caninos y molares temporales. A dicha paciente se le trató clínicamente mediante exodoncias seriadas y se muestra su evolución posterior al tratamiento dental. Objetivos: Lograr entender de mejor manera el proceso de la erupción dental en base a la actual bibliografía. Materiales y métodos: Se realizó una revisión bibliográfica con palabras claves: "erupción dental", "extracciones seriadas", "retención dental" y "evolución dental". La paciente fue evaluada y tratada ortodóncicamente, mediante extracciones seriadas y se realizaron controles dentales periódicos con toma de radiografía panorámica para evaluar su evolución. Conclusión: El folículo dental y el retículo estrellado son las estructuras encargadas de generar el proceso eruptivo del diente mediante la interacción de diversas moléculas. Estas moléculas deben encajar dentro de un contexto para que cada diente erupcione de manera independiente.

Introduction: This article delves into the most accepted theories about the dental eruption process in today's literature and, from this perspective, presents the clinical case of a 12-year-old patient who presented retention of temporary canines and molars. This patient was treated clinically by means of serial extractions and her evolution after dental treatment is shown. Objectives: This article delves into the most accepted theories about the dental eruption process in today's literature and, from this perspective, presents the clinical case of a 12-year-old patient who presented retention of temporary canines and molars. This patient was treated clinically by means of serial extractions and her evolution after dental treatment is shown. Materials and methods: A bibliographic review was carried out with key words: "dental eruption", "serial extractions", "dental retention" and "dental evolution". The patient was evaluated and treated orthodontically by serial extractions and periodic dental check-ups were carried out with panoramic radiography to evaluate her evolution. Conclusion: The dental follicle and the stellate reticulum are the structures responsible for generating the eruptive process of the tooth through the interaction of various molecules. These molecules must fit into a context for each tooth to erupt independently.

Abstract Objective: To assess the knowledge of pregnant women regarding their child's oral health. Material and Methods: A questionnaire was developed and the 1st section comprised sociodemographic variables. The second section contained questions about the eruption of teeth, fluoride importance, cariogenic food, and dental visits. The questionnaire was shared electronically via a link to the receptionist of the gynaecologist at different health centres of Najran to be filled by expectant mothers. The convenient sampling method was used to collect the responses. Data were presented using descriptive statistics. Results: A total of 572 pregnant women participated in this survey. Three hundred and fifteen (55.1%) knew that 1st primary tooth erupts at the age of 6 months. The majority of the respondents (n=332) agreed that toothbrushes and toothpaste could be used to clean a child's teeth; only 5.4%, 10%, and 24.5% preferred miswak, mouthwash, and toothbrush, respectively. Participants were well familiar with cariogenic food and occasionally allowed their children to take it. They have enough knowledge about fluoride toothpaste, but they were not familiar with the benefits of fluoride varnish. Almost 50% of the respondents agreed that the child should visit the dentist within six months, and 27.4% said they should visit the dentist whenever there is a problem. Conclusion: Almost 50% of participants showed a positive attitude towards most questions. However, there is a need to improve their behaviour and knowledge about many aspects of dental care.

There is no much published data on the mothers' false beliefs about signs and symptoms associated with teething in Sudan. Aim: This cross-sectional hospital-based study was conducted to assess mothers` knowledge about infant teething process and to evaluate mothers' practices used to alleviate teething disturbances in Gadarif city, eastern Sudan. Methods: Questionnaires were used to collect data. Multivariate logistics regression models were performed and adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated. Results/Conclusion: Of a total of 384 participating mothers, 126 (32.8%) had good knowledge about infant teething. The mothers' knowledge was associated with a higher number of children in the family (adjusted odds ratio [AOR] = 1.14) and with having a job (AOR = 2.22). Mothers residing in rural areas (AOR = 0.40) and mothers with lower than secondary education (AOR = 0.43) were less likely to have good knowledge about teething. Diarrhea (88.5%), fever (86.5%), an urge to bite (76.6%), and poor appetite (71.9%) were the signs and symptoms most attributed to teething by mothers. Only the mother's knowledge about teething was associated with reporting fever as a sign. A considerable number (317; 82.6%) of mothers reported performing "Dokhan" (acacia wood smoke), 313 (81.5%) preferred to administer paracetamol or other systemic analgesics, 262 (68.2%) agreed that a child with tooth eruption should be taken to a hospital or health center, and 216 (56.3%) believed that antibiotics relieved symptoms related to teething

O objetivo deste trabalho foi comparar a cronologia de erupção do primeiro molar permanente em crianças de ambos os sexos, residentes na zona urbana e rural do munícipio de Santa Helena - PR, Brasil. Foi realizado um estudo transversal com 154 crianças da zona rural e 300 crianças da área urbana de 04 a 07 anos (48 a 84 meses). Os primeiros molares avaliados foram considerados irrompidos quando qualquer porção de sua coroa estivesse clinicamente visível. A média de idade para erupção do primeiro molar permanente se mostrou de 72 a 83 meses. Destes, o grupo da zona rural apresentou uma média para idade de erupção mais precoce. Contudo, verificou-se um resultado considerável em crianças na faixa de 48 a 59 meses (4 anos), mostrando mais uma vez a erupção precoce nas crianças da zona rural. Este dente irrompeu primeiro na mandíbula, irrompendo primeiro nas meninas do que nos meninos, e o dente 46 foi o que mais se mostrou presente. A média de idade para erupção do primeiro molar permanente correspondeu àquela descrita pela literatura aos seis anos, mas não correspondeu ao atraso na erupção das crianças residentes em zona rural. Bem como este dente irrompeu primeiro na mandíbula... (AU)

The objective of this study was to compare the chronology of eruption of the first permanent molar in children of both sexes, living in the urban and rural areas of the city of Santa Helena-PR, Brazil. A cross-sectional study was carried out with 154 children from the rural area and 300 children from the urban area from 4 to 7 years old (48 to 84 months). The first molars evaluated were considered erupted when any portion of their crown was clinically visible. The average age for eruption of the first permanent molar was 72 to 83 months. Of these, the rural group had an earlier average age for eruption than the urban group. However, a considerable result was found in children 48-59 months showing once again the early eruption in rural children. This tooth erupted first in the jaw, erupting first in girls rather than boys, and tooth 46 was most present. The mean age of eruption of the first permanent molar corresponded to that described in the literature at age six, but did not correspond to the delayed eruption of children living in rural areas. Just like this tooth erupted in the jaw first... (AU)

Abstract: This study aimed to verify, through a longitudinal follow-up, the pre-, peri- and postnatal factors associated with the eruption of deciduous teeth. The study was nested in a Birth Cohort Study conducted in Pelotas, a Southern Brazilian city. Mothers were followed prenatally and their children were followed-up perinatally, at 3 and 12 months of age. The outcome was the number of teeth at 12 months, and exploratory variables included maternal habits and characteristics, anthropometric measures of children and mothers, and socioeconomic and demographic information. Data were collected through interviews with the mother and children's clinical exam. Poisson regression models were used for the analysis. Participants included 4,014 children with a mean number of erupted teeth at 12 months of 5.50. After adjustments, a lower mean number of teeth was observed in children from non-white mothers, early preterm children, and shorter children at birth and at 12 months. A higher number of teeth was observed for mothers with excessive weight gain during pregnancy, mothers who smoked during pregnancy, weightier children at birth and at 12 months, and for children with larger heads at birth and at 12 months. Our findings suggest that maternal and children characteristics influenced primary tooth eruption.

Introducción: La disostosis cleidocraneal es un trastorno genético raro con patrón hereditario. Sus rasgos patognomónicos son la aplasia clavicular, fontanelas y suturas abiertas, múltiples anomalías dentales. Su origen se relaciona con alteraciones en el gen RUNX2, importante para la síntesis de CBFA1, que a su vez funciona como un conformador óseo y un diferenciador de osteoblastos. Caso clínico: Paciente de 11 años con características clínicas de CCD, se corroboran los antecedentes genéticos hereditarios y alteraciones dentales relacionados con disostosis cleidocraneal. Resultado: A tres años de tratamiento se observa mejor definición facial, la erupción de piezas permanentes retenidas y mejor función masticatoria. Conclusión: Mejorar la calidad de vida del paciente con tratamientos interceptivos y el conocimiento de las alteraciones causadas por el síndrome, así como el trabajo interdisciplinario (AU)

Introduction: Cleidocranial dysostosis is a rare genetic disorder with a hereditary pattern. Its pathognomonic features are clavicular aplasia, fontanelles and open sutures, multiple dental anomalies. Its origin is related to alterations in the RUNX2 gene, important for the synthesis of CBFA1, which in turn functions as a bone conformer and an osteoblast differentiator. Clinical case: Patient with eleven years old with clinical characteristics of CCD, hereditary genetic background, and dental alterations related to cleidocranial dysostosis are corroborated. Result: After three years of treatment, the facial definition is better, the eruption of permanent pieces retained and better chewing function. Conclusion: Improve the quality of life of the patient with interceptive treatments and the knowledge of the alterations caused by the syndrome, as well as the interdisciplinary work (AU)

ABSTRACT Objective: To evaluate the skill of orthodontists and oral/maxillofacial surgeons (OMFS) in providing a prognosis of mandibular third molars spontaneously erupted, through follow-up panoramic analysis. Methods: 22 orthodontic patients treated without extraction, presenting spontaneously erupted mandibular third molars (n = 44) were analyzed through panoramic serial radiographs. The first panoramic radiograph was obtained just after orthodontic treatment (PR1), in patients aging from 13 to 19 years. A second panoramic radiograph (PR2), was obtained in average two years later. The radiographs were randomly analyzed by 54 specialists, 27 orthodontists and 27 OMFS, to obtain the opinion about the approach to be adopted to these teeth in PR1. Then, another opinion was collected by adding a serial radiograph (PR1+2). Results: The concordance of the answers was moderate for OMFS (Kappa 0.44; p< 0.0001) and significant for orthodontists (Kappa 0.39; p< 0.0001). In the analysis of the first radiograph (PR1) of the spontaneously erupted molars, OMFS indicated extraction in 44.5% of cases, while orthodontists indicated in 42%, with no difference between groups (p= 0.22). In PR1+2 analysis, orthodontists maintained the same level of extraction indication (45.6%, p= 0.08), while surgeons indicated more extractions (63.2%, p< 0.0001). Conclusions: Orthodontists and OMFS were not able to predict the eruption of the third molars that have erupted spontaneously. Both indicated extractions around half of the third molars. A follow-up analysis, including one more radiograph, did not improve the accuracy of prognosis among orthodontists and worsened for OMFS.

RESUMO Objetivo: Avaliar a habilidade de ortodontistas e cirurgiões bucomaxilofaciais (CBMF) em propor um prognóstico para terceiros molares inferiores. Métodos: Foram analisados 22 pacientes tratados ortodonticamente sem extração, cujos terceiros molares inferiores irrompidos espontaneamente (n= 44) foram avaliados por meio de radiografias panorâmicas seriadas. A primeira radiografia foi obtida logo após o tratamento ortodôntico (RX1), entre 13 e 19 anos de idade. A segunda radiografia (RX2) foi avaliada dois anos depois, em média. As radiografias foram analisadas aleatoriamente por 54 especialistas, 27 ortodontistas e 27 CBMFs, para obter sua opinião sobre a abordagem a ser adotada na RX1. Em seguida, outra opinião foi coletada adicionando-se a segunda radiografia seriada (RX1+2). Resultados: A concordância das respostas foi moderada para os CBMFs (Kappa = 0,44; p< 0,0001) e significativa para os ortodontistas (Kappa = 0,39; p< 0,0001). Após analisar apenas a primeira radiografia (RX1) dos molares antes deles irromperem espontaneamente, os CBMFs indicaram extração em 44,5% dos casos; enquanto os ortodontistas, em 42%, sem diferença entre os grupos (p= 0,22). Na análise de RX1+2, os ortodontistas mantiveram o mesmo nível de indicação de extração (45,6%, p= 0,08), enquanto os cirurgiões passaram a indicar mais extrações (63,2%, p< 0,0001). Conclusões: Ortodontistas e CBMFs não foram capazes de predizer a erupção de terceiros molares por meio da análise de uma única radiografia panorâmica, indicando extrações em cerca da metade dos terceiros molares examinados. Uma análise de acompanhamento, incluindo mais uma radiografia, não melhorou a precisão do prognóstico entre os ortodontistas, e piorou entre os CBMFs.

La erupción dental es un proceso dinámico que se inicia cuando se forma el germen dentario en su cripta de desarrollo hasta que el diente hace su aparición en boca. El folículo dental tiene un papel importante en la formación coronal y radicular del diente, y es esencial para la erupción dentaria. Para que un diente entre en erupción es necesario que exista resorción del hueso alveolar que cubre la corona del diente, de modo que se forme un camino a través del cual el diente se moverá. Para esto, se producen una serie de procesos moleculares y celulares localizados y programados genéticamente que permiten la osteogénesis y la osteoclastogénesis del hueso alveolar a fin de formar la vía de erupción. El objetivo de esta revisión es dar a conocer los posibles eventos celulares y moleculares que influyen en el proceso de erupción dentaria, ya que el mecanismo exacto aún es desconocido. (AU)

Dental eruption is a dynamic process, which begins when the dentary germ forms in the developmental crypt and finally appears in the mouth. The dental follicle has an important role in the coronal and root formation of the tooth and is essential for tooth eruption, without which the tooth could not erupt. Tooth eruption requires resorption of the alveolar bone that covers the crown of the tooth to form a path to the eruption and biological processes by which the tooth can move through this eruption path. Tooth eruption needs localized and genetically programmed molecular and cellular processes that allow osteogenesis and osteoclastogenesis of the alveolar bone to form the eruption path. The objective of this review was to describe the possible cellular and molecular events that influence the tooth eruption process, since the exact mechanism remains unknown. (AU)

La erupción dental es un proceso estrictamente regulado y programado espacial y temporalmente. El objetivo del trabajo fue estudiar el efecto de la exposición prenatal a fluoruro de sodio (NaF) sobre los eventos morfológicos y celulares que ocurren en el hueso supracoronal del primer molar de crías de rata durante la etapa preeruptiva. Se emplearon crías (n=6-8 por grupo) provenientes de madres que bebieron crónicamente agua con diferentes concentraciones de F- en forma de NaF durante la gestación y lactancia: control y NaF (50 mg/L). En cortes histológicos de la mandíbula de crías de 3 y 10 días se analizaron parámetros de histomorfometría estática en la zona supracoronal de la canastilla ósea a la altura del primer molar inferior: volumen óseo trabecular [BV/TV (%)], número de osteoclastos por milímetro (N.Oc/mm) y las variables indirectas: número de trabéculas [Tb.N (1/mm)], espesor [Tb.Th (µm)] y separación trabecular [Tb.Sp (µm)]. En crías de 15 días se midió el grado de erupción [TED (µm)] del primer molar inferior. Los resultados se analizaron con el test "t" de Student considerando diferencias significativas a p<0,05. El análisis histomorfométrico demostró un incremento en el BV/TV (%) del hueso supracoronal (p<0,01) asociado con disminución del N.Oc/mm (p<0,01) en crías de 3 y 10 días expuestas prenatalmente al F-. El grado de erupción dental fue menor en animales expuestos prenatalmente al F- en comparación con los controles (p<0,01). En conclusión, los resultados observados en la mandíbula de crías expuestas durante la etapa prenatal y posnatal temprana al F- sugieren un efecto disruptivo sobre la actividad resortiva necesaria para formación del canal eruptivo. (AU)

Tooth eruption is a tightly regulated and spatially and temporally programmed process. The aim of this study was to examine the effect of prenatal NaF exposure on the morphological and cellular events that occur in the supracoronal area of bony crypt of the first rat molar during the preeruptive stage. Offspring from two groups of rats were used (6-8 per group): Control and 50 mg/L NaF. The treatment was performed during pregnancy and lactation. Suckling pups were euthanized at 3-, 10- and 15-days-old by cervical dislocation. Mandibles were removed and histologically processed to obtain buccolingual sections stained with H&E. In sections of first mandibular molar of 3- and 10-days-old pups, the following static histomorphometric parameters were evaluated: trabecular bone volume [BV/TV (%)] and number of osteoclasts (N.Oc/mm). Also, indirect parameters were obtained: trabecular number [Tb.N (1/mm)], trabecular thickness [Tb.Th (µm)], and trabecular separation [Tb.Sp (µm)]. The degree of tooth eruption [TED (µm)] was determined. Results are expressed as mean ± SE and analyzed by Student t-test. Histomorphometric analysis showed an increase in the BV/TV (%) of the bone crypt of 3- and 10- days-old pups exposed to NaF (p <0.01); this increase was associated with a decrease in the N.Oc/mm (p <0.01). TED of mandibular first molar was lower in prenatal NaF exposed group than in control group (p<0.01). In conclusion, the increased BV/TV and the lower N.Oc observed in the bone crypt of 3- and 10- days-old pups from mothers treated with NaF suggested a disruptive effect triggered by F- on the formation events of the eruptive pathway in the offspring.

RESUMEN Introducción: en la práctica clínica ortodóncica es de capital importancia el conocimiento de la erupción dentaria. Este es un proceso largo e íntimamente relacionado con el crecimiento y desarrollo del resto de las estructuras craneofaciales. Objetivo: caracterizar el ritmo de brote de los distintos grupos dentarios en niños con dentición permanente de la Escuela «Vietnam Heroico¼, en Santa Clara, desde marzo de 2016 a febrero de 2017. Métodos: se realizó un estudio epidemiológico, descriptivo, longitudinal y prospectivo, en niños de la Escuela «Vietnam Heroico¼, en Santa Clara, desde marzo de 2016 a febrero de 2017. El universo de estudio estuvo constituido por 506 niños de ambos sexos, entre 5 y 13 años de edad. La muestra quedó finalmente conformada por 142 individuos. Se obtuvieron valores medios ponderados del ritmo de brote mensual para cada grupo dentario, y la media de la duración clínica de la erupción según sexo y raza de los pacientes. Resultados: se encontraron diferencias entre arcadas y hemiarcos en cuanto al ritmo de brote. Los dientes maxilares erupcionaron más rápido que los mandibulares. Las féminas fueron más adelantadas en el ritmo de brote en incisivos centrales y primeros molares, y más retrasadas en primeras bicúspides superiores e inferiores, caninos inferiores e incisivos laterales superiores. Conclusiones: el canino y primer premolar presentaron el mayor ritmo de brote en ambos maxilares. No se encontraron diferencias significativas entre los sexos. La duración clínica de la erupción fue menor en la raza negra y demoró aproximadamente seis meses en ambos sexos.

ABSTRACT Introduction: knowledge of tooth eruption is of great importance in clinical orthodontic practice. This is a long process closely related to the growth and development of the rest of the craniofacial structures. Objective: to characterize rhythm of tooth eruption of the different dental groups in children with permanent dentition at "Vietnam Heroic" School, in Santa Clara, from March 2016 to February 2017. Methods: an epidemiological, descriptive, longitudinal and prospective study was conducted on children from Vietnam Heroic" School in Santa Clara from March 2016 to February 2017. The study universe consisted of 506 children of both genders, between 5 and 13 years of age. The sample was finally made up of 142 individuals. Weighted average values of the monthly rhythm of tooth eruption for each dental group were obtained, and the average clinical duration of tooth eruption according to gender and race of the patients. Results: differences were found between arcades and hemiarchs in terms of rhythm of tooth eruption. Maxillary teeth erupted faster than mandibular ones. Females were more advanced in the rhythm of tooth eruption in central incisors and first molars, and more delayed in upper and lower first bicuspids, lower canines and upper lateral incisors. Conclusions: canine and first premolar presented the highest rhythm of tooth eruption in both jaws. No significant differences were found between the genders. The clinical duration of tooth eruption was shorter in black people and it took approximately six months in both genders.

RESUMEN: Uno de los problemas con mayores consecuencias tanto estéticas como funcionales en ortodoncia es la impactación de caninos maxilares (ICM) siendo principal motivo de reabsorciones radiculares de dientes adyacentes. Actualmente se carece de estudios que describan la reabsorción radicular por ICM a través de tomografía computarizada conebeam (TCCB) en la población chilena. El objetivo del estudio fue describir a pacientes entre 8 a 18 años, que presentan ICM (o riesgo de ella), tanto en las características de la impactación canina como en la reabsorción radicular presentada en incisivos laterales (IL) y en otros dientes adyacentes. En este estudio retrospectivo, 135 datos de TCCB fueron seleccionados por conveniencia, de los cuales 181 caninos presentaron ICM. Fueron analizadas las variables edad, sexo, tipo de ICM (unilateral o bilateral), localización bucolingual (vestibular o palatino), lado de impactación (derecho o izquierdo), reabsorción radicular en el incisivo lateral y registro de el o los dientes anexos afectados por reabsorción radicular (incisivo central y/o premolares). Además en el caso de reabsorción de IL fue analizada la reabsorción tridimensionalmente a través de la ThreeDimensional Leeds Orthodontic Root Resorption Target Scale (3D-LORTS). La ICM en la muestra seleccionada tuvo una edad promedio de 12 años, una relación por sexo mujeres:hombres de 1,5:1, frecuentemente de tipo unilateral, en el lado derecho y una localización bucolingual palatina (64,1 %) por sobre la vestibular (35,9 %). La reabsorción radicular alcanzó un 35,9 %, de la cual un 27,6 % involucró a IL y un 8,3 % en dientes anexos adyacentes. En cuanto a la distribución tridimensional de la reabsorción radicular, la más frecuente involucró el tercio apical (60 %), con compromiso pulpar o severo (40 %), involucrando solo una cara, la palatina (54 %). Ninguna de las variables anteriores consideradas, demostró diferencias estadísticas con la reabsorción radicular de incisivos laterales.

ABSTRACT: One of the problems with greatest aesthetic and functional consequences in orthodontics is the Impaction of Maxillary Canines (ICM) being the main reason for root resorption of the adjacent teeth. Currently there are no studies describing root resorption by ICM through cone beam computed tomography (CBCT) in the Chilean population. The main objective of the study was to describe patients between 8 and 18 years old, who presented with ICM (or risk thereof), with the characteristics of canine impaction as well as root resorption presented in lateral incisors (IL) and in other adjacent teeth. In this retrospective study, 135 CBCT subjects were selected for convenience, of which 181 canines presented ICM. The variables were analyzed: age, sex, type of ICM (unilateral or bilateral), buccolingual location (vestibular or palatal), side of impaction (right or left), root resorption in the lateral incisor and registration of adjacent teeth affected by resorption radicular (central incisor and/or premolars). In addition, when reabsorption of IL was observed, three-dimensional analysis was made using the Three-Dimensional Leeds Orthodontic Root Resorption Target Scale (3D-LORTS). The ICM in the selected sample had an average age of 12 years, a ratio by sex of women:men of 1.5:1, frequently of unilateral type, on the right side and with palatine buccolingual location (64.1 %) above the vestibular (35.9 %). Root resorption reached 35.9 %, of which 27.6 % presented in the IL and 8.3 % in adjacent teeth. Regarding the three-dimensional distribution of root resorption, the most frequent involved the apical third (60 %), with pulpal or severe damage (40 %), in only one location, the palatine (54 %). None of the above variables considered showed statistical differences with the root resorption of lateral incisors.

Objetivo: Determinar la asociación entre los factores internos que influyen en la gestante hasta la vigésima semana de gestación y que producen alteraciones en la cronología y la secuencia de erupción de los dientes primarios de sus niños. Metodología: El presente estudio fue observacional, analítico y retroprospectivo. La población y muestra estuvo compuesta por 150 niños, atendidos en el servicio de crecimiento y desarrollo (CRED) que presentaron alguna alteración en la cronología o secuencia de erupción de los dientes temporal, y las historias clínicas de sus respectivas madres, que acuden al Centro de Salud Materno Infantil Pachacútec Perú-Corea (Callao, 2017). Para ello, debieron cumplir los siguientes criterios de inclusión: madres que acepten participar con su menor hijo en el proyecto de investigación, niños entre 6 y 31 meses que acuden al servicio de crecimiento y desarrollo (CRED), que presenten alguna alteración en la cronología o secuencia de erupción dental. Niños con peso y talla normal, y con lactancia exclusiva los primeros seis meses de vida. Madres que tengan sus historias clínicas completas con sus controles de gestación, que acudan al centro de salud y tengan entre 20 y 35 años. Los criterios de exclusión fueron los siguientes: madres o niños que no pertenezcan a la jurisdicción del centro de salud, niños con desnutrición o con alimentación basada en fórmula (artificial), niños con algún síndrome o prematuros, niños con enfermedades sistémicas. Resultados: Los factores que influyeron en la gestación se evaluaron por medio de la prueba estadística Chi cuadrado y se trabajaron a un nivel de significancia de 0,05. Al analizar la asociación entre las enfermedades infecciosas y las alteraciones en la cronología se encontró que en enfermedades como las ITU, que son las más comunes (82,8%), presentó un nivel de significancia p = 0,000. En el caso de la asociación entre las enfermedades infecciosas y las alteraciones en la secuencia se encontró que, en las enfermedades como las ITU, un 88.1% presentaron un nivel de significancia p = 0,008. Se hallaron porcentajes menores en enfermedades como la hipertensión (4,1%), la salud mental (3,3%) y enfermedades nutricionales (9,8%), en lo que respecta a la cronología En el caso de la secuencia, fueron la hipertensión (2,4%), la salud mental (2,4%) y las enfermedades nutricionales (7,1%). Con respecto al sexo y la asociación con alteraciones en la cronología de erupción, los resultados fueron del 49,2% para el sexo femenino y el 50,8% para el masculino (p = 0,271). Con respecto al sexo y la asociación con alteraciones en la secuencia de erupción, los resultados fueron del 54,8% para el femenino y el 45,2% para el masculino (p = 0,600). Conclusiones: Se encontró asociación significativamente estadística entre la enfermedad infecciosa y la alteración en la cronología con el retraso de la erupción de los dientes primarios. Se encontró asociación significativamente estadística entre la enfermedad infecciosa y las alteraciones en la secuencia de erupción; sin embargo, no fue tan categórica como la alteración en cronología, por lo que se sugiere profundizar la investigación.

ABSTRACT Objective: This article describes the orthodontic treatment performed on an adult patient with multiple dental losses. Case report: A female patient, 20 years and 4 months old, presented with the following conditions: absence of teeth #26, #35, #36 and #46; semi-impacted tooth #48; inclined molars adjacent to an edentulous space; canines and premolars in a Class II relationship; a convex profile; biprotrusion; and forced lip sealing. Results: Space in the region of tooth #26 was closed, as well the space of tooth #46; tooth #48 erupted and followed mesial movement passively; space of the region of tooth #35 was maintained for the placement of a dental implant; uprighting of tooth #37 was obtained. Aesthetic and functional goals of the treatment were achieved. Results remained stable 10 years after the end of the treatment. Conclusion: The modified helical loop could be effectively used in orthodontic mechanics to close edentulous spaces. Passive semi-impacted mandibular third molar eruption and mesialization can occur in adults when proper space is provided.

ABSTRACT The starting point for the treatment of unerupted teeth should consider the fact that, biologically, the pericoronal follicle maintains the ability to release EGF and other mediators responsible for eruption over time. The eruptive events may be guided and directed, so that teeth may occupy the space prepared to receive them in the dental arch, as showed in the case presented to evidence the following principle to be considered in these cases: "Regardless of the position of an unerupted tooth, it may be biologically directed to its place in the dental arch. The orthodontist should apply a mechanics to guide it and park it at its site."

RESUMO Os dentes não irrompidos devem ter como ponto de partida, para seu tratamento, o fato de que biologicamente o folículo pericoronário mantém ao longo do tempo a capacidade de liberar o EGF e outros mediadores responsáveis pela erupção. Pode-se guiar e direcionar os eventos eruptivos para que os dentes ocupem o seu espaço preparado para recebê-los na arcada dentária, como revela o caso apresentado para sedimentar o seguinte princípio a ser considerado para esses casos: "Independentemente da posição que um dente não irrompido se apresente, há como, biologicamente, direcioná-lo para o seu local na arcada dentária. Cabe ao ortodontista aplicar uma mecânica que o leve até o local e lá o estacione."

ABSTRACT: Tooth eruption requires resorption of the alveolar bone interposed between the tooth germ and the oral mucosa (coronal bone). The cells responsible for bone resorption are the osteoclasts and their activity can be reduced or inactivated by estrogen hormone. We aimed to investigate the effects of estrogen on the process of tooth eruption in rats. Thirty-three Wistar rats, aged two-to-17-days, were divided into control, sham and estrogen-treated groups. After daily injections with estrogen, the animals were euthanized and the jaws removed and processed for histological analysis. We performed clinical examination, morphological analysis, quantification of the number of osteoclasts on the surface of the coronal bone and immunohistochemical analysis of estrogen receptor type alpha (ERα). Estrogen therapy was effective, which could be confirmed by the higher estrogen plasma levels on treated animals. However, it had no effect on tooth development or tooth eruption. Progressive bone resorption was observed and the number of osteoclasts on coronal bone was not affected on hormoneinjected animals, allowing tooth to erupt at the same time observed in untreated animals. Immunohistochemistry for ERα confirmed the presence of this type of receptor in osteoclasts, osteoblasts and osteocytes. Taken together, our results showed that estrogen stimulation was not sufficient to decrease the number of osteoclasts on the coronal bone, supporting the idea that, although estrogen may have a protective activity on bone resorption, this may not apply to the alveolar bone that is meant to be resorbed during eruptive process.

RESUMEN: La erupción dental requiere la resorción del hueso alveolar interpuesto entre el germen dental y la mucosa oral (hueso coronal). Las células responsables de la resorción ósea son los osteoclastos y su actividad puede reducirse o inactivarse por la hormona del estrógeno. Objetivos: apuntamos a investigar los efectos del estrógeno en el proceso de la erupción dental en ratas. Treinta y tres ratas Wistar, de dos a 17 días de edad, se dividieron en grupos de control, Sham y se trataron con estrógenos. Los animales fueron eutanizados después del tratamento con estrógeno y se procesaron las mandíbulas para el análisis histológico. Se realizó el examen clínico, el análisis morfológico, la cuantificación del número de osteoclastos en la superficie del hueso coronal y el análisis inmunohistoquímico del tipo de receptor de estrógeno alfa (ERα). La terapia de estrógeno fue eficaz, lo que podría ser confirmado por los niveles plasmáticos más altos de estrógeno en los animales tratados. Sin embargo, no se observó ningún efecto sobre el desarrollo de los dientes o la erupción dental. Se observó una resorción ósea progresiva y el número de osteoclastos en el hueso coronal no se vio afectado en los animales inyectados con hormonas, permitiendo que el diente erupcionó durante el mismo período de tiempo observado en animales no tratados. La inmunohistoquímica para el ERα confirmó la presencia de este tipo de receptor en los osteoclastos, osteoblastos y osteocitos. Nuestros resultados mostraron que la estimulación del estrógeno no fue suficiente para reducir el número de osteoclastos en el hueso coronal confirmando que, si bien el estrógeno puede tener una actividad protectora en la resorción ósea, esto puede no se aplica al hueso alveolar que está destinado a ser rerecurrido durante el proceso eruptivo.

Introduction: Deciduous teeth play an important role in proper growth. Tooth eruption is a complicated process in which different mechanisms are involved. Early or delayed tooth eruption depends on different factors, with the impact of some already established. There are apparent controversy regarding the effect of some factors on time of the first deciduous tooth eruption among the conducted studies. The current study aimed to evaluate factors affecting the time of the first deciduous tooth eruption. Materials and Methods: One hundred and sixty eligible infants referring to the healthcare centers of Tabriz, Iran, were randomly selected; the demographic data including weight and height at birth, head circumference, mother's age and level of education, birth rank in the family and type of feeding were recorded, in addition to the time of the first deciduous tooth eruption. Data were analyzed using SPSS version 21 by ANOVA and t test.Results: Out of 54.1% female and 45.9% male participating infants, 78.3% had normal weight at birth. Results showed a significant relationship between weight at birth and timing of the first deciduous tooth eruption, among the evaluated factors. Conclusions: Although no significant relationship was observed between gender, type of feeding, mother's level of education and birth rank in the family, and time of the first deciduous tooth eruption, there was a significant relationship between the weight at birth and the timing of the first deciduous tooth eruption. Infants with higher or lower abnormal weight at birth had delayed deciduous tooth eruption.

Introducción: los dientes primarios juegan un papel importante en el crecimiento adecuado. La erupción dental es un proceso complexo en el que intervienen diferentes mecanismos. La erupción temprana o tardía de los dientes depende de diferentes factores, con el impacto de algunos ya establecido. Existe controversia entre los estudios realizados con respecto al efecto de algunos factores que afectan la erupción del primero diente primario. El presente estudio tuvo como objetivo evaluar los factores que afectan el periodo de erupción del primero diente primario o temporal. Materiales y Métodos: Ciento sesenta bebés referidos a los centros de salud de Tabriz, Irán, fueron seleccionados al azar; Se registraron los datos demográficos, incluidos el peso y la estatura al nacer, la circunferencia de la cabeza, la edad y el nivel de educación de la madre, el rango de nacimiento en la familia y el tipo de alimentación, además del momento de la primera erupción del diente primario. Los datos fueron analizados por ANOVA y t-test utilizando SPSS versión 21. Resultados: de los lactantes participantes (54,1% femeninos, 45,9% masculinos) el 78,3% tenía peso normal al nacer. Entre los factores evaluados, los resultados mostraron una relación significativa entre el peso al nacer y el momento de la erupción del primero diente primario. Conclusiones: aunque no se observó una relación significativa entre sexo, tipo de alimentación, nivel de educación de la madre y rango de nacimiento en la familia, y el period de erupción del primero diente primario, hubo una relación significativa entre el peso al nacer y el momento de la primera erupción dental decidua. En los lactantes con peso anormal al nacer se había retrasado la primera erupción de los dientes primarios.

RESUMEN: Este estudio se realizó para evaluar la presentación de cambios histopatológicos tempranos en sacos pericoronarios de terceros molares incluidos sanos. Sesenta y un tejidos pericoronarios de terceros molares incluidos, clínicamente asintomáticos y sin evidencia radiográfica de anomalía del saco pericoronario, se extrajeron por diferentes razones. Las muestras se fijaron y procesaron de forma rutinaria y se tiñeron con hematoxilina-eosina antes de la evaluación. Se estandarizaron los diagnósticos concluyendo que toda muestra que presente metaplasia escamosa del epitelio reducido del órgano del esmalte (EEE) se considerará cambio quístico temprano. De las muestras presentadas, el 28 % mostró metaplasia escamosa sugerente de cambio quístico temprano. Esta variación histológica del tejido pericoronario fue significativamente mayor en los pacientes menores de 20 años de edad, sexo femenino, terceros molares mandibulares, en inclusión ósea y en pacientes que no informaron sintomatología local previa (P = 0,05). Estos hallazgos sugieren que la ausencia de semiología clínica y radiográfica en terceros molares incluidos no necesariamente indica ausencia de alteraciones en el tejido pericoronario de los mismos.

ABSTRACT: This study was performed to evaluate the presentation of early histopathological changes in pericoronal healthy third molars. Sixty-one pericororonitis tissues third molars, without radiographic evidence of abnormality in pericoronary sack, extracted for various reasons. The samples were fixed and processed routinely and stained with hematoxylin-eosin before evaluation. Diagnostic standardized concluding that all this shows that squamous metaplasia of the reduced enamel organ (EEE) is considered cystic epithelium were early change. Of the samples submitted, 28 % showed squamous metaplasia early suggestive of cystic change. This histological tissue pericoronary variation was significantly higher in patients under 20 years of age, female gender, mandibular third molars, including in bone and in patients who reported no previous local symptoms (P = 0.05). These findings suggest that the absence of clinical and radiographic semiology third molars does not necessarily indicate the absence of alterations in tissue pericoronary thereof.
