RESUMEN
Background: Skeletal malocclusion is common among populations. Its severity often increases during adolescence, yet it is frequently overlooked. The introduction of deep learning in stomatology has opened a new avenue for self-health management. Methods: In this study, networks were trained using lateral photographs of 2109 newly diagnosed patients. The performance of the models was thoroughly evaluated using various metrics, such as sensitivity, specificity, accuracy, confusion matrix analysis, the receiver operating characteristic curve, and the area under the curve value. Heat maps were generated to further interpret the models' decisions. A comparative analysis was performed to assess the proposed models against the expert judgment of orthodontic specialists. Results: The modified models reached an impressive average accuracy of 84.50% (78.73%-88.87%), with both sex and developmental stage information contributing to the AI system's enhanced performance. The heat maps effectively highlighted the distinct characteristics of skeletal class II and III malocclusion in specific regions. In contrast, the specialist achieved a mean accuracy of 71.89% (65.25%-77.64%). Conclusions: Deep learning appears to be a promising tool for assisting in the screening of skeletal malocclusion. It provides valuable insights for expanding the use of AI in self-monitoring and early detection within a family environment.

OBJECTIVES: This study aimed to compare and evaluate different transverse width indices for diagnosing maxillary transverse deficiency (MTD), a common malocclusion characterized by uncoordinated dental arches, crossbites, and tooth crowding. MATERIALS AND METHODS: Sixty patients aged 7-12 years were included in the study, with 20 patients diagnosed with MTD and 40 normal controls. Transverse width indices, including maxillary width at the buccal alveolar crest and lingual midroot level, as well as at the jugal process width, were measured. Differences between these indices and their corresponding mandibular indices were used as standardized transverse width indices. The reference range of these indices was determined and evaluated. Receiver operating characteristic (ROC) analysis was performed to evaluate their diagnostic ability. RESULTS: The transverse width indices and standardized transverse width indices of the MTD group were significantly smaller than those of the control group, except for the jugal process width. The evaluation of the reference range and ROC analysis revealed that the difference of the maxillomandibular width at buccal alveolar crest was the most accurate diagnostic method. CONCLUSIONS: The jugal point analysis method may not be suitable for diagnosing MTD. Instead, measuring the difference in maxillomandibular width at the buccal alveolar crest proves to be a more reliable and accurate diagnostic method for MTD.

Introduction: The subject of this article is the discovery of dento-dental disharmony (DDD) at the end of treatment. Lack of diagnosis is the source of this type of disappointment. Material and Method: The diagnosis of DDD is not easily accessible on clinical examination and the compensations it generates mask it, especially if it is associated with other dysmorphoses. The use of indices, the best-known of which is Bolton's, enables diagnosis with the setup, a pre-treatment model which also has many other prognostic interests. Results: Once DDD has been considered, it can be resolved by adapting dental volumes, either by subtraction or addition. Conclusion: Advances in computerized diagnosis with artificial intelligence are opening up new avenues for the systematic diagnosis of DDD.
Introduction: L'objectif de cet article est de présenter, à l'issue de la découverte d'une dysharmonie dento-dentaire (DDD) en fin de traitement orthodontique, les modalités de sa prise en charge. Le défaut de diagnostic initial est la source de ce type de déconvenue. Matériel et méthode: Le diagnostic de la DDD n'est pas facilement accessible à l'examen clinique, les compensations qu'elle génère la masquent, surtout si elle est associée à d'autres dysmorphoses. L'utilisation d'indices, dont le plus connu est celui de Bolton, permet le diagnostic avec le setup, maquette de prétraitement qui a aussi beaucoup d'autres intérêts pronostiques. Résultats: Une fois prise en compte, la DDD trouve sa solution par l'adaptation des volumes dentaires soit par soustraction amélaire soit par addition. Conclusion: Les avancées du diagnostic informatisé avec l'intelligence artificielle ouvrent des portes pour intégrer le diagnostic systématique de la DDD.

BACKGROUND: The term "stereognosis" comes from neurology and describes the capacity to distinguish objects solely by touch. AIM: The aim of this research study was to compare the neuromotor ability of the tongue in patients with malocclusion and tongue dysfunction with and without superficial anesthesia on the tip of the tongue and hard palate. MATERIALS AND METHODS: The study included 132 patients aged 6-13 years. Using a spatula for speech therapy and a visual evaluation while swallowing saliva, all individuals were identified as having swallowing dysfunctions and divided into three groups: study group (children with malocclusions and tongue dysfunctions) - 44 patients, comparator group (children with malocclusions and without tongue dysfunctions) - 44 patients, and control group (children without malocclusions or tongue dysfunctions) - 44 patients. The Koczorowski methods were used for the stereognostic tests. RESULTS: Age, sex, and malocclusion were taken into account during the differential analysis. The study and comparison groups, study and control groups, and the comparator and control groups all showed statistically significant differences from one another. According to the results, tongue dysfunction affects patients' ability to coordinate their movements with their senses at a developing stage. CONCLUSION: Patients with malocclusions that are made worse by tongue dysfunctions have poorer oral stereognostic sensibility. Speech therapy and interdisciplinary specialist orthodontic treatment are required for individuals with impaired oral perception who are still in the developmental stage and have abnormal tongue position and function.

The gradual movement of a tooth away from the occlusal plane is called infraocclusion or reinclusion. Reincluded teeth are most often deciduous molars, and permanent teeth are less frequently affected. Depending on the level of the infraocclusion, the severity of the disorder is classified as mild, moderate, or severe. The etiology of the phenomenon is not fully known. Tooth submerging can lead to serious complications, such as abnormal position of adjacent teeth, displacement of the bud of the permanent successor, shortening of the dental arch, or developmental disturbances of alveolar process. Early diagnosis of the tooth infraocclusion and regular monitoring of its progression help to avoid serious permanent sequelae. The treatment of reinclusion often involves only observation. However, in some cases, the therapeutic procedure requires interdisciplinary treatment by specialists from various fields of dentistry. This study presents current methods of diagnosis and treatment of patients with submerged teeth.

OBJECTIVES: Literature presents conflicting results regarding malocclusions, Obstructive Sleep Apnea (OSA) and sleep bruxism in children with ADHD. Aim of this study was to evaluate the prevalence of these parameters. METHODS: A prospective study was conducted on 40 consecutive ADHD children referred to the Paediatric Dentistry Unit of Fondazione Policlinico Universitario "A. Gemelli" IRCCS, Rome. All subjects underwent an orthodontic examination and were screened for OSA and sleep bruxism. Data were compared to a sex- and aged-matched control group. RESULTS: Prevalence of high risk of OSA in children with ADHD was 62.5% compared to 10% in the control group (p < .00001). No differences were found in any of the occlusal variables examined between children with ADHD and controls (p > .05). An increased prevalence of sleep bruxism was observed in ADHD children (40%) compared to controls (7.5%) (p < .001). CONCLUSIONS: A higher prevalence of OSA risk and probable sleep bruxism were observed in ADHD patients compared with controls. No significant differences were observed in malocclusions d.

INTRODUCTION: Occlusal cant (OC) is a malocclusion trait that lacks accurate clinical assessment methods. The occlusal canting identifying tool (OCIT) was invented and patented as a clinical tool to accurately identify and quantify the degree of maxillary OC. This study aimed to 1) develop a prototype of the OCIT, 2) verify the functionality of the OCIT and 3) assess the validity and reliability of the OCIT. MATERIALS AND METHODS: A patented OCIT design was revised, and the dimensions were finalized, followed by a three-dimensional conceptual prototype design that was reviewed and approved by the inventors. Verification was performed using a digital angle gauge to determine the accuracy of the bubble level as well as the angle between the bite plate and the protractor. For laboratory validation, 40 orthodontists measured the simulated OC at (0°, 2°, 4°, 6° and 8°) on five phantom heads using the OCIT. A reliability assessment of the tool was performed in three occasions by one orthodontist using the same laboratory settings. RESULTS: The OCIT was prototyped from a medical-grade stainless steel alloy (316 L). Verification assessment revealed that the accuracy error of the bubble level (0.316° ± 0.028°) was statistically significant but clinically insignificant, while that of the angle between the bite plate and protractor (0.100° ± 0.050°) was statistically insignificant. Validation assessment showed high validity of the OCIT with no statistically significant difference between the OCIT and the reference values, having more errors in identifying smaller OC degrees compared to larger OC degrees. The intraclass correlation coefficient indicated the high reliability of the OCIT. CONCLUSION: The OCIT was verified and proven to be a valid and reliable clinical tool that accurately evaluates the degree of OC.

The evidence to characterize oral health during adolescence in Costa Rica is limited. This lack of adequate research makes it difficult to develop appropriate health policies for this subgroup of the population. This is particularly important because adolescence is the period during which good health habits must take root in order to foster good physical and cognitive development. This study aims to determine the prevalence of tooth loss, bleeding on probing and malocclusion in Costa Rican male adolescents at the ''Colegio Técnico Profesional San Agustín'' (St. Augustine's Technical High School) located in the province of Cartago. Data was collected from 428 male adolescents aged 12-22 years in a cross-sectional study during 2019. Prevalence of tooth loss was calculated as the number of individuals having lost at least one tooth. The average number of teeth lost by individuals was also recorded. The bleeding on probing was an indicator used as a proxy parameter for monitoring periodontal health where the presence of bleeding on probing and calculus was also recorded. Malocclusion was measured using the Dental Aesthetic Index (DAI). The results showed that the prevalence of tooth loss, bleeding on probing and malocclusion was of 19%, 70.0% and 98%, respectively. It was also found that 81% of the participants had all their teeth, 11% had lost 1 tooth, 8% had lost more than one tooth of which 0.5% had lost more than 5 teeth. Considering a general classification of periodontal problems based on bleeding on probing and presence of calculus, the prevalence of periodontal problems increases to 92%. Regarding the DAI, the category identifying a very severe malocclusion was the most prevalent in the sample (88%). It is alarming the high prevalence of tooth loss, bleeding on probing, and malocclusions in a sample of Costa Rican male adolescents, compared to similar studies in other countries. The overarching conclusion of this study is that oral diseases represent an important health problem that urgently need proper public health action.
La evidencia para caracterizar la salud bucal durante la adolescencia en Costa Rica es limitada. Esta falta de investigación adecuada dificulta el desarrollo de políticas de salud convenientes para este subgrupo de la población. Esto es particularmente importante porque la adolescencia es el período durante el cual se deben arraigar buenos hábitos de salud para fomentar un buen desarrollo físico y cognitivo. Este estudio tiene como objetivo determinar la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión en adolescentes varones costarricenses del Colegio Técnico Profesional San Agustín ubicado en la provincia de Cartago. Se recopilaron datos de 428 adolescentes varones de 12 a 22 años en un estudio transversal durante 2019. La prevalencia de pérdida de piezas dentales se calculó como el número de individuos que habían perdido al menos una pieza dental. También se registró el número promedio de dientes perdidos por individuos. El sangrado al sondeo fue un indicador utilizado como parámetro para el seguimiento de la salud periodontal donde también se registró la presencia de sangrado al sondeo y cálculo dental. La maloclusión se midió utilizando el Índice Estético Dental (DAI, por sus siglas en inglés). Los resultados mostraron que la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión fue del 19%, 70,0% y 98%, respectivamente. También se encontró que el 81% de los participantes tenían todos sus dientes, el 11% había perdido 1 pieza dental, el 8% había perdido más de una pieza dental, de los cuales el 0,5% había perdido más de 5 piezas dentales. Considerando una clasificación general de problemas periodontales basada en sangrado al sondeo y presencia de cálculo, la prevalencia de problemas periodontales aumenta al 92%. En cuanto al DAI, la categoría que identifica una maloclusión muy severa fue la más prevalente en la muestra (88%). Es alarmante la alta prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusiones en una muestra de adolescentes varones costarricenses, en comparación con estudios similares en otros países. La conclusión general de este estudio es que las enfermedades bucodentales representan un importante problema de salud que necesita urgentemente una acción adecuada de salud pública.

ABSTRACT Objective: To analyze the relationship between malocclusion and bullying and its impact on the well-being and quality of life of students from low social development areas. Material and Methods: This cross-sectional study included 243 schoolchildren between 10 and 17 years. Malocclusion was analyzed using Dental Aesthetic Index. Bullying and self-perception of the impact of one's oral condition on quality of life and interpersonal relationships were assessed by questions from National Survey of Schoolchildren's Health and Child Perceptions Questionnaire 11-14 (CPQ11-14). Data were analyzed using the Spearman correlation coefficient and Mann-Whitney tests, considering groups: 10-11, 12-14 and 15-17 years. Results: No correlation was observed between malocclusion and bullying. However, in the 12-14 group, poor correlations were found between malocclusion and the CPQ11-14 (0.226) and between malocclusion and being shy/embarrassed due to oral aspects (0.298). Positive correlations were observed between bullying and the impact on the quality of life in the 10-11 (0.420) and 12-14 (0.425) groups. In the older group, a positive correlation (0.724) was observed between the concern about what others think of their oral health and the impact on their quality of life. Conclusion: There was no evidence of a relationship between malocclusion and bullying. However, the oral conditions negatively affected the interpersonal relationships and the student's quality of life.

Introducción: la etiología de las maloclusiones se encuentra relacionada a factores genéticos y ambientales, siendo relevantes los hábitos lesivos orales en ella; por lo que en un concepto de Salud Integral de los niños, debemos contar no solo con el rol activo preventivo del odontólogo sino también de pediatra. Método: crear guía clínico práctica para médicos pediatras, que permitan identificar sistemáticamente hábitos no fisiológicos vinculados a maloclusiones. Resultado: el pediatra con los conocimientos básicos podrá elaborar revisiones preventivas durante los controles periódicos de rutina. Discusión: considerar la atención en equipo multidisciplinario, con énfasis en la prevención, punto donde todo el equipo de salud debe contribuir. Conclusiones: consideramos que los efectos sobre el crecimiento y desarrollo provocados por hábitos lesivos orales/funciones no fisiológicas tendrán mayor o menor repercusión según la edad en que se inicia el hábito. Si actuamos de manera temprana tendremos más posibilidades de modificar el patrón de crecimiento de los maxilares y el desarrollo de los arcos dentarios. Se impone entonces un interrogatorio y examen funcional precoz y sistemático para la detección de desviaciones y trastornos funcionales en niños, así como enfocar los tratamientos desde equipos multidisciplinarios (odontólogo, pediatra, fonoaudiólogo, otorrinolaringólogo, psicólogo) y alcanzar resultados de excelencia.
Introduction: the etiology of malocclusions is related to genetic and environmental factors, and oral injurious habits are relevant in it; therefore, in a concept of integral health of children, we should count not only on the active preventive role of the dentist but also of the pediatrician. Method: to create a practical clinical guide for pediatricians that will allow the systematic identification of non-physiological habits linked to malocclusions. Result: the pediatrician with basic knowledge will be able to elaborate preventive check-ups during routine periodic check-ups. Discussion: consider multidisciplinary team care, with emphasis on prevention, a point to which the entire health team should contribute. Conclusions: we consider that the effects on growth and development caused by harmful oral habits/non-physiological functions will have greater or lesser repercussions depending on the age at which the habit begins. If we act early we will have more possibilities of modifying the growth pattern of the jaws and the development of the dental arches. Therefore, an early and systematic interrogation and functional examination is necessary to detect deviations and functional disorders in children, as well as to focus the treatments from multidisciplinary teams (dentist, pediatrician, speech therapist, otorhinolaryngologist, psychologist) and achieve excellent results.
Introdução: a etiologia das más oclusões está relacionada a fatores genéticos e ambientais, e hábitos orais nocivos são relevantes para ela; portanto, em um conceito de saúde integral das crianças, devemos confiar não apenas no papel ativo preventivo do dentista, mas também no do pediatra. Método: criar um guia clínico prático para que os pediatras identifiquem sistematicamente os hábitos não fisiológicos ligados às más oclusões. Resultado: o pediatra com conhecimentos básicos será capaz de desenvolver check-ups preventivos durante check-ups periódicos de rotina. Discussão: considerar os cuidados de equipe multidisciplinar, com ênfase na prevenção, um ponto para o qual toda a equipe de saúde deve contribuir. Conclusões: consideramos que os efeitos no crescimento e desenvolvimento causados por hábitos orais nocivos/ funções não-fisiológicas terão maiores ou menores repercussões dependendo da idade em que o hábito começa. Se agirmos cedo, teremos mais chances de modificar o padrão de crescimento das mandíbulas e o desenvolvimento dos arcos dentários. O questionamento precoce e sistemático e o exame funcional são, portanto, necessários para a detecção de desvios e distúrbios funcionais em crianças, assim como a aproximação de tratamento de equipes multidisciplinares (dentista, pediatra, fonoaudiólogo, otorrinolaringologista, psicólogo) e a obtenção de excelentes resultados.

Introducción: Los principios biomecánicos de cabeza y cuello cobran un interés especial en el campo de la ortodoncia y la ortopedia dentomaxilofacial. Cualquier anomalía debe ser analizada y tratada dentro del sistema cráneo-cérvico-mandibular con un enfoque integral. Objetivo: Describir la relación entre el patrón esquelético maxilomandibular sagital, la postura corporal y la posición cráneo-cervical en adolescentes. Métodos: Estudio descriptivo, transversal, desarrollado entre marzo del 2018 a junio del 2019. La muestra estuvo conformada por 105 adolescentes del séptimo grado de la ESBU "Eduardo Anoceto Rega", de Santa Clara. Se determinó el patrón esquelético maxilomandibular de clase I, II y III midiendo la convexidad facial del cefalogramas de Ricketts; la posición cráneo-cervical de extensión, normoinclinación y flexión con el cefalograma de Rocabado; el tipo de postura con el método de Bricot. Se siguieron las normas éticas y fueron aplicados los estadígrafos chi cuadrado, F de Fisher y estadístico de Welch. Resultados: La postura D (espalda plana y plano escapular anterior) predominó en todas las clases esqueléticas 64,76 por ciento de los adolescentes, seguido de la postura C (plano escapular posterior). En la clase II, después de la postura D siguió la postura B (plano escapular y glúteo alineados con aumento de las curvas anteriores) con un 6,22 por ciento. Predominó la normoinclinación cráneo-cervical 46,67 por ciento y la flexión 42,86 por ciento. En la clase III predominó la flexión y el ángulo posteroinferior de Rocabado mayor respecto a las otras clases esqueléticas de 107º. Conclusiones: La posición del cráneo respecto a las estructuras cervicales, asociada a las características de cada clase esquelética, puede ser un indicador importante en el diagnóstico morfológico. A pesar de las muchas investigaciones en este campo, aún no se puede hablar de consenso en cuanto al grado de relación entre la postura craneocervical y las maloclusiones(AU)
Introduction: Head and neck biomechanical principles are particularly relevant in the fields of orthodontics and dentomaxillofacial orthopedics. Any anomaly should be analyzed and treated within the cranio-cervical-mandibular system applying a comprehensive approach. Objective: Describe the relationship between the sagittal maxillomandibular skeletal pattern, body posture and craniocervical position in adolescents. Methods: A descriptive cross-sectional study was conducted from March 2018 to June 2019. The study sample was 105 adolescents attending seventh grade at Eduardo Anoceto Rega junior high school in Santa Clara. Determination was made of maxillomandibular skeletal patterns Classes I, II and III, measuring the facial convexity in Ricketts' cephalograms, craniocervical extension, normal inclination and flexion positions with Rocabado's cephalogram, and posture type with Bricot's method. Ethical standards were complied with. Use was made of the statistical tests chi-square, Fisher's F and Welch's. Results: Posture D (flat back and anterior scapular plane) prevailed in all skeletal classes: 64.76 percent of the adolescents, followed by posture C (posterior scapular plane). In Class II, posture D was followed by posture B (scapular and gluteal plane aligned with increased anterior curves): 6.22 percent. A predominance was observed of craniocervical normal inclination: 46.67 percent and flexion: 42.86 percent. In Class III, Rocabado's flexion and posteroinferior angle were more common than the remaining 107º skeletal classes. Conclusions: Cranial position with respect to cervical structures, according to the characteristics of each skeletal class, may be an important indicator in morphological diagnosis. Despite the large number of studies conducted in this field, consensus has not been achieved about the degree of relationship between craniocervical posture and malocclusions(AU)

Abstract Objective: To evaluate the psychosocial impact of malocclusion and self-esteem in adolescents in the Amazon region. Material and Methods: A cross-sectional study was carried out with 212 adolescents with 12-year-old enrolled in all public schools in the Boca do Acre (Amazonas, Brazil). Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) assessed the psychosocial impact of malocclusion. The self-perception of the need for orthodontic treatment was evaluated by the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) and Global Negative Self-evaluation (GSE), the adolescent's self-esteem. The malocclusion was clinically evaluated by the Dental Aesthetic Index (DAI). The variables with p<0.20 in the individual analyses were tested in multiple logistic regression models, and those with p<0.10 remained in the model. The adjusted odds ratio (OR) was estimated with a 95% confidence interval (CI). Results: Adolescents with low self-esteem were 2.20 (95% CI: 1.23-3.93) times more likely to have a more significant impact on dental aesthetics (p<0.05). When verified by domains, the adolescents with low self-esteem had 2.33 (95% CI: 1.31-4.17) and 1.93 (95% CI: 1.09-3.42) times more likely to impact the psychological and social domains of the PIDAQ, respectively. Conclusion: Self-esteem influenced adolescents' perception of dental aesthetics in the domains related to psychological and social impact (AU).

ABSTRACT Purpose: to describe the changes in speech and dental occlusion in children with cleft lip and palate and verify their association with each other and with the time of primary plastic surgeries. Methods: a cross-sectional study with collected data on the subjects' identification, age at the time of primary surgeries, and clinical assessment of speech and dental occlusion. The chi-square test, Fisher's exact test, and t-test were used to verify the associations between the variables at the 5% significance level (p < 0.05). Results: the sample comprised 11 children aged 6 to 10 years, most of whom were males, self-reported white, with trans-incisive foramen cleft, predominantly on the left side. The mean age at lip repair surgery was 6 months, and 13 months at palatoplasty. Among the main dental occlusion changes, posterior and anterior crossbite stood out. All the subjects presented changed speech, with a prevalence of cases with dentoalveolar and palatine deformities, followed by passive and active changes. Subjects with anterior crossbite tended to have undergone primary lip repair surgery at a mean of four months earlier than the subjects without anterior crossbite. Conclusions: the associations between speech and dental occlusion changes, and between these and the time of primary plastic surgeries were not statistically significant. Even though it is known that early lip repair surgery is ideal to favor oral functions and aesthetics, the results revealed a tendency towards anterior crossbite, in these subjects.
RESUMO Objetivos: descrever alterações de fala e dento-oclusais em crianças com fissuras labiopalatinas, verificar a associação entre si e destas com a época das cirurgias plásticas primárias. Métodos: estudo transversal, com coleta de dados de identificação, idade nas cirurgias primárias, avaliação clínica dento-oclusal e da fala. Utilizou-se o teste Qui-quadrado, teste exato de Fisher e teste t para verificar as associações entre as variáveis, com um nível de significância de 5% (p < 0,05). Resultados: amostra composta por 11 crianças entre seis e dez anos, sendo a maioria do sexo masculino, etnia autodeclarada branca e fissura transforame incisivo (com prevalência de acometimento do lado esquerdo). A média da realização da labioplastia foi aos seis meses e palatoplastia aos treze meses. Dentre as principais alterações dento-oclusais, destacam-se: mordida cruzada posterior e mordida cruzada anterior. Todos os sujeitos apresentaram alteração de fala com prevalência de alterações em casos com deformidades dentoalveolares e palatinas, seguidas pelas alterações passivas e alterações ativas. Houve tendência dos sujeitos que apresentaram mordida cruzada anterior terem sido submetidos à labioplastia primária, em média, quatro meses antes dos sujeitos sem mordida cruzada anterior. Conclusões: as associações entre alterações de fala e dento-oclusais e destas com a época das cirurgias plásticas primárias não foram estatisticamente significantes, e ainda que se saiba que a labioplastia precoce é o ideal para favorecer funções orais e estética, os resultados demonstraram tendência a mordida cruzada anterior nestes sujeitos.

Abstract: This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3-5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach's alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.

ABSTRACT Objective: To investigate the possible relationship between early admission to the school of children in early childhood and oral health conditions (OH) and nutritional status (NS). Material and Methods: Cross-sectional study conducted with 140 children aged 3-4 years, selected for convenience, in 4 public schools in the city of São Paulo, Brazil, during 2016, divided into children with early (IE) and late (IL) admission at school. Comparisons between groups were performed for the presence of overweight / obesity (OW / OB), caries lesions (CL), malocclusion (MO) and dental biofilm (DB), in addition to socioeconomic and dietary data. Multiple regression analysis was applied to determine the association between age of admission at school and OH and NS. Results: Children with IE had CL = 28.1%; DB = 46.9%; MO = 54.7% and OW / OB = 25.9%. Children with IE had IL = 29.8%; DB = 35.1%; MO = 61.4% and OW / OB = 30.8%. No significant association was found between age of admission at school and CL: 1.40 (0.53-3.73) 0.490; DB: 0.51 (0.22-1.16) 0.112; MO: 1.77 (0.77-4.05) 0.173 and OW / OB: 1.27 (0.55-2.92) 0.568, [OR (95% CI) p]. Conclusion: The age of admission at school of children in early childhood did not show a significant association with OH and NS.

Aim: To evaluate the association between the frequency of malocclusions in the anterior sextant with dentition type, age, and sex. Material and methods: A descriptive, transversal and prospective study was carried out, in a convenience sample of 200 patients between 3 and 14 years old, of both sexes who attended the pediatric dentistry clinic of Dentistry Faculty from Autonomous University of Tlaxcala, Mexico. A dentist was standardized by a direct method (k=0.998, p=0.0001). Results: Crossbite and edge to edge bite were the most frequent (18% and 17% respectively), in no case the alterations in the previous sextant were related to sex, except altered overjet with age and dentition type (likelihood ratio=18,169, p=0.0001) (X2=18.820, p=0.0001). Conclusion: These observations highlight the importance of the diagnosis of possible alterations in the occlusion of the anterior sextant in both dentitions, in order to preventatively avoid major sequelae.
Objetivo: Evaluar la asociación entre la frecuencia de maloclusiones en el sextante anterior con el tipo de dentición, la edad y el sexo. Material y Métodos: Se llevó a cabo un estudio descriptivo, transversal, prolectivo en una muestra por conveniencia conformada por 200 pacientes entre 3 y 14 años, de ambos sexos atendidos en la clínica de odontopediatría de la Facultad de Odontología, de la Universidad Autónoma de Tlaxcala. Se estandarizó a una cirujana dentista a través del método directo (k=0,998, p=0,0001). Resultados: La mordida cruzada y borde a borde fueron las que se presentaron con mayor frecuencia (18% y 17% respectivamente), en ningún caso las alteraciones en el sextante anterior se relacionaron con el sexo, no así, el resalte alterado que se asoció con la edad y con el tipo de dentición (Razón de verosimilitudes=18.169, p=0.0001, X2=18.820, p=0.0001). Conclusión: El comportamiento observado permite reconocer la importancia del diagnóstico de las alteraciones en la oclusión del sextante anterior en ambas denticiones, con el propósito de actuar anticipadamente para evitar secuelas mayores.

Las compresiones del maxilar superior son alteraciones transversales por discrepancia óseo-dentaria. .En la dentición mixta temprana puede establecerse la estrechez mediante índices que relacionan el tamaño dental con el ancho transversal del arco dentario. Se analizaron 33 modelos superiores de niños en el tercer período de desarrollo clínico según Barnett. Se estableció la estrechez realizando el análisis métrico del arco dental mediante el índice de Pont. Se describió la anomalía de posición anterior según las siguientes variables: A) Apiñamiento dentario: 1-Escalón de los dientes anterosuperiores; 2-Rotación mesial de los cuatro incisivos; 3-Rotación mesial de los incisivos centrales y rotación distal de los incisivos laterales y 4-Rotación distal de los incisivos centrales. B) Ausencia de apiñamiento: 1-Reabsorción atípica y 2- Ausencia de reabsorción atípica. Las anomalías de posición y/o reabsorciones atípicas anteriores en este período de desarrollo clínico se asocian a estrechez transversal del maxilar superior Siendo la malposición más frecuente la rotación mesial de los cuatro incisivos, siguiendo las reabsorciones atípicas y el escalón de los dientes anterosuperiores, luego la rotación mesial de los incisivos centrales y distal de los laterales y por último la rotación distal de los incisivos centrales (AU)
Inside the traverse alteration of the maxillary the compressions are described as uni or bilateral where an imbalance is settled down between the dental size and the size of the maxillary causing alterations in the position of the teeth. In the early mixed teething the narrowness of the maxillary can be settled by means of indexes that relate the dental size with the traverse width of the dental arch. Thirty models of the maxillary of children according to Barnett's third development period were analyzed. The metrical analysis of the dental arch form was carried out through Pont's index. The theoretic values were compared with the real ones establishing the deviations of the norm that is to say the narrow nest. Out of the 30 cases analyzed, 40% presented mesial rotation of the 4 incisors; 27% showed a stop of the front teeth; 27% atypical reabsorption; 20% mesial rotation of the central incisors and distal rotation of the lateral incisors and the 10% presented a distal rotation of the central incisors. With regard to the front atypical discrepancy 36.66% of the cases had a discrepancy above 6 mm and the 23.33% below 3 mm (AU)

RESUMEN La retención dentaria es común encontrarla en la clínica de ortodoncia, los caninos maxilares son los de mayor solicitud de tratamiento por su importancia estética. Sin embargo, no es frecuente la retención de dientes temporales. Su etiología no está bien definida pero se considera de carácter multifactorial. Se presentó una paciente del sexo femenino de 12 años y medio de edad, con ausencia de 15 y 13, presencia de 53 y mesogresión del 16. Al examen radiográfico se observó retención de 55, 15 y 13, este último en transposición incompleta con el 12. Después de un profundo análisis se decidió exéresis del 55 y alineación al arco dentario de 15 y 13, mediante colocación de un dispositivo, con el empleo del sistema de cementado directo en el acto quirúrgico. Se estableció una oclusión funcional y estética aceptable, con particular cuidado de la integridad de los dientes vecinos y sus tejidos blandos. Las retenciones constituyen maloclusiones dentarias complejas y de difícil pronóstico y tratamiento, más aún cuando son múltiples. Se requiere de estudio y tratamiento multidisciplinario (AU).
ABSTRACT It is common to find teeth retention in Orthodontics clinic; maxillary canines, due to their esthetical importance, are the ones the patients ask to be treated more frequently. Nevertheless, temporary teeth retention is not frequent. Its etiology is not clear, but it is considered multifactorial. The authors present the case of a female patient, aged 12 years and a half, without 15 and 13 teeth, presence of 53 and mesogression of 16. At the radiographic examination, the retention of 55, 15 and 13 was found, and also the incomplete transposition of 13 and 12. After deeply analyzing the case, the orthodontists decided the removal of 55 and aligning 15 and 13 to dental arch, placing a device with the system of direct cementing at the moment of the surgery. It was established a functional occlusion and an acceptable esthetics, particularly caring for the neighboring teeth and their soft tissues. Retentions are complex dental malocclusions, of difficult prognosis and treatment, mainly when they are multiple. They require study and multidisciplinary treatment (AU).

RESUMEN El tratamiento de Ortodoncia en pacientes con síndrome de Down, ha sido un tema debatido durante muchos años por los especialistas debido a las deficiencias físicas, mentales y a la dificultad de estos en la cooperación con el tratamiento. El objetivo de este trabajo es mostrar resultados adecuados de tratamiento ortodóncico en una paciente femenina de 12 años de edad con síndrome de Down. La niña acudió a consulta acompañada de su mamá y de su abuela solicitando tratamiento por presentar los dientes virados. En el examen clínico se observó rotación marcada de 11 y 21 mayor de 900 que afecta su estética facial. Se explicó a la familia lo difícil que podía resultar el tratamiento a esta adolescente con necesidades especiales, a la que habría que aplicar una fuerza ortodóncica que genera marcada molestia y pudiera presentarse una escasa tolerancia al dolor. La familia aseguró su cooperación. Se decidió emprender la terapia para lo cual se diseñó un plan de tratamiento en dos etapas. En una primera etapa se empleó aparatología ortodóncica removible y en una segunda etapa aparatología fija. Al concluir el tratamiento se logró resolver de manera satisfactoria el motivo de consulta con buena cooperación por parte de la paciente y su familia. El éxito del tratamiento se debió a la satisfactoria cooperación de la paciente y al establecimiento de una relación favorable ortodoncista-paciente-familia (AU).
ABSTRACT The Orthodontics treatment in patients with Down syndrome has being a theme debated by specialist during many years, due to the physical and mental deficiencies of this kind of patients and their difficulty in cooperating with the treatment. The aim of this article is showing the adequate results of the orthodontic treatment in a female patient aged 12 years with Down syndrome. The girl assisted to consultation with her mother and grandmother asking treatment for having crooked teeth. At the physical examination it was observed a remarked rotation of 11 and 21 of more than 900, affecting her facial esthetics. Doctors explained to relatives that the treatment could result very difficult to this teenager with special requirements due to the application of an orthodontic force generating great discomfort in this girl, possibly having a scarce tolerance to pain. The relatives agreed to cooperate. They decided to start the therapy, and a two-stage plan was designed. In the first stage, removable orthodontic braces were used, and fixed ones were used in the second stage. At the end of the treatment the cause of the consultation was successfully solved with a good cooperation of the patient and her relatives. The success of the treatment was achieved due to the satisfactory cooperation of the patient and the establishment of a favorable relationship orthodontist-patient-family (AU).

Abstract Objective: To evaluate the prevalence of deleterious oral habits and its effect on occlusion in school going children from 7 to 13 years old, in Aseer region of Saudi Arabia. Material and Methods: A cross-sectional study was conducted by clinical examination for the total sample of 750, who were attending private/ government schools in Aseer region school. Students were selected by stratified cluster random sampling. Clinical findings of each oral habits, including assessment of malocclusion, were examined involving the following parameters, i.e., crowding, spacing, open bite, crossbite and deep bite. Logistic regression analysis was conducted. Results: Boys had 26.2 % of crowded teeth, while 16.3% of girls were found to have crowded teeth; the difference was found to be significant (p=0.002). Spacing was present in 26.4% of boys and 16.7% girls; a significant difference was found between the two (p=0.002). Sleep bruxism was observed more among male subjects than females with a statistically significant difference in detrimental habits (p<0.001). Those subjects having tongue thrusting are 1.264 times at more risk of having crowded teeth than those with no tongue thrusting. Conclusion: There was a high prevalence of malocclusion associated with harmful oral habits in children. This highlighted the need to implement programs of oral care and health education for preventive orthodontic treatment at an early age.
