RESUMO

ABSTRACT: Oromandibular limb hypogenesis syndrome is a rare developmental anomaly and only a few cases are reported with complete surgical and orthodontic rehabilitation. An adult male patient with isolated hypoglossia, micrognathism, hypodontia, (oromandibular limb hypogenesis syndrome type I A) was treated with a combination of distraction osteogenesis and orthodontic intervention. The patient was followed up for the duration of 6 years from his first visit to 4 years after the surgery. The combined procedure resulted in successful and satisfactory treatment of the patient by restoring facial aesthetics, occlusal balance, and functional harmony. However, there was not enough tongue enlargement due to late surgical intervention. The objective of this report is to describe the etiology of hypoglossia, the consequences for oral function, and to share our experience from the oral rehabilitation during the treatment procedure.

RESUMO

Dimension, number and shape alterations are frequently observed dental anomalies. Objective: The aim of this study was to map the frequency, the preferred location and the most prevalent types of supernumerary teeth, in the studied population. In addition, to assess the interference that supernumerary teeth may cause in the ectopic eruption of the normal dental series teeth. Methods: This is an observational retrospective study. Data collection was performed by evaluation of dental records of patients treated in an orthodontic clinic. Patients' radiographs, photographs and gypsum dental models were analyzed and data recorded in protocol files, by previously trained undergraduate and postgraduate students. Records from 1984 to 2019 were evaluated, and evaluation lasted two months. Data were stored in Microsoft Office Excel (version 2016) for descriptive analysis. Results: From the 920 patients' records analyzed, 2.7% presented at least one supernumerary tooth, with preferred location on the anterior maxillary area and mandibular parapremolar area. The most prevalent type was the supplemental tooth, with normal eruption orientation and normal alveolar location. Conclusion: The supernumerary teeth of the studied population showed little interference in the ectopic eruption of the normal dental series. Most of the supernumerary teeth were impacted, and, approximately one third of the supernumerary teeth showed deviated eruptions.


Introdução: Alterações de dimensão, número e forma são anomalias dentárias comumente observadas. Objetivo: O objetivo foi mapear a frequência de dentes supranumerários na população estudada, sua localização preferida e os tipos mais prevalentes. Além disso, avaliar a interferência que os dentes supranumerários podem causar na erupção ectópica da série dental normal. Métodos: A pesquisa possui desenho retrospectivo observacional. A coleta de dados foi realizada pela avaliação de prontuários odontológicos dos pacientes atendidos em uma clínica ortodôntica. Foram analisados radiografias, fotografias e modelos de gesso dental dos pacientes e as informações foram registradas em arquivos de protocolo do estudo. A coleta de dados foi realizada por uma estudante de graduação e uma da pós-graduação, previamente calibradas. A coleta durou dois meses e foram avaliados registros de 1984 a 2019. Os dados foram tratados no programa Microsoft Office Excel (version 2016) com análise descritiva dos dados. Resultados: Dos 920 prontuários analisados, 2,7% apresentavam pelo menos um dente supranumerário, com localização preferida na área superior anterior e na área parapremolar mandibular. O tipo mais prevalente foi o dente suplementar, com orientação de erupção normal e localização alveolar normal. Conclusão: Os dentes supranumerários da população estudada neste estudo mostraram pouca interferência na erupção ectópica da série dental normal. A maioria dos dentes supranumerários estava em posição de impactação. E, aproximadamente um terço dos dentes supranumerários apresentaram desvios de erupção.

RESUMO

BACKGROUND: Patients undergoing orthognathic skeletal correction present with a variety of comorbidities that may affect surgical outcomes. The purpose of this study was to determine how patient risk factors and operative technique contribute to complication rates after orthognathic surgery in the era of patient-specific implants. METHODS: Retrospective cohort analysis was conducted of pediatric patients undergoing Le Fort I osteotomy, bilateral sagittal split osteotomy, and/or genioplasty from 2014 to 2018. Patient risk factors, operative characteristics, and postoperative outcomes were gathered and compared with appropriate statistics. RESULTS: Ninety-four patients met inclusion criteria, with an overall 1-year complication rate of 11.7 percent (11 of 94). Patient-specific mandibular plates are significantly associated with infection (p = 0.009; OR, 8.8), occurrence of any complication (p = 0.003; OR, 8.3), readmission (p < 0.001; OR, 11.1), and reoperation (p < 0.001; OR, 11.4). In patients with syndromes or history of cleft lip/palate, patient-specific mandibular plates are associated with infection (p = 0.006; OR, 10.3), readmission (p < 0.001; OR, 21.6), and reoperation (p < 0.001; OR, 22.9). In multivariate regression controlling for age, sex, syndrome status, and orofacial cleft history, use of patient-specific mandibular plates was associated with infection (p = 0.017; adjusted OR, 12.5), any complication (p = 0.007; adjusted OR, 11.8), readmission (p = 0.001; adjusted OR, 17.9), and reoperation (p = 0.001; adjusted OR, 18.9). CONCLUSIONS: In the era of patient-specific orthognathic surgery, syndromic status and use of patient-specific mandibular plates are associated with increased infection, readmission, and reoperation because of hardware-related complications. The authors' data support increased caution and counseling with use of patient-specific mandibular implants in patients with syndromic status, history of orofacial cleft, and history of previous maxillomandibular surgery given increased risk of hardware-related complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

The differential diagnosis of a masticator space (MS) lesion is broad, owing in part to the multiple structures contained within such a small region. It is also because the MS is adjacent to many of the other deep spaces within the head and neck, which can act as gateways for disease spread. Therefore, emergency radiologists must be familiar with anatomy of the MS, as well as adjacent spaces in order to provide an accurate diagnosis to the referring clinician. This article illustrates the anatomy and common pathologies within the MS using a case-based multimodality approach. Common masticator space pathologies can be categorized into inflammatory/infectious, neoplastic, and vasoformative lesions. Important imaging features of MS lesions and patterns of disease spread will be discussed, with the aim of making this complex deep space more approachable in the emergent setting.

RESUMO

Abstract Objective: To investigate the prevalence and characteristics of canine transpositions and to evaluate associated dental anomalies in a pediatric population. Material and Methods: This study was carried out by evaluating the panoramic radiographs of 11.750 patients ranging in ages from 6 to 17 presented to a pedodontic clinic over 5 years. The patients with canine transposition were included in the study. Age at diagnosis, gender, classification and location of transposition, presence of other dental anomalies were recorded. Differences were analyzed using the Chi-squared test. Results: Canine transposition was detected in 73 teeth from 69 patients (0.6%). Transpositions were more common in girls than in boys (55.1%). Transposed canine teeth were more frequently observed unilaterally (89%). The most commonly found transposition type was type 2 (42%). A total of 49.3% of 69 patients had retained primary canine teeth, 20.3% had congenitally missing teeth, and 11.6% had peg-shaped, microdont lateral incisors. Impacted teeth excluding third molars and taurodontism were also observed. Conclusion: Although the canine transpositions are generally asymptomatic in children in the period of growth and development, the importance of early diagnosis is crucial to prevent various clinical problems.

RESUMO

Background: To evaluate 91 cases of Stafne bone defect (SBD) in panoramic radiographs (PR) to determine the prevalence of different SBD variants, considering age, gender, and side. Additionally, to assess the most frequent imaging features of SBD. Material and Methods: Participant data were collected from 91 SBD cases with PR imaging. First, SBDs were classified according to their location, as anterior, posterior, or ramus variant. SBD imaging features were classified according to radiographic imaging findings, assessing margins, degree of internal radiolucency, shape, topographic relationship between the defect and mandibular border, location of the defect according to mandibular teeth, and locularity. The topographic relationship between the SBD and the mandibular canal was described for the inferior variant only. Mean sizes were also described. Results: A total of 92 SBD cases were evaluated from 91 radiographs. One case presented multiple defects. Mean patient age was 60.80 years. Men were more affected than women. The most frequent SBD variant was the posterior variant, and the least frequent was the ramus variant. The most observed radiographic features were thick sclerotic bone margin in the entire contour of the defect, partially radiolucent internal content, oval shape, continuity with mandible base without discontinuity of mandible border, third molar region location, and unilocular shape. With the posterior variant only, the most common topographic relationship between the defect and the upper wall of the mandibular canal was the defect located below the upper wall and continuous with the inferior wall of the mandibular canal. Conclusions: The knowledge of common SBD radiographic imaging features in PR can help dental practitioners with the differential diagnosis of SBD

RESUMO

Fonament: La micrognàtia transversal (MT) és una alteració del creixement ossi i de la relació dental que impedeix el funcionament adequat de l'aparell masticatori. Objectiu: Avaluar si hi ha associació entre la freqüència d'MT amb la lactància materna de menys de sis mesos, la presència d'hàbits de succió digital, la respiració bucal i l'absència d'espais fisiològics. Mètode: Es va dur a terme un estudi transversal examinant 273 infants mexicans de cinc anys, de tots dos sexes. Abans de l'enquesta es va estandarditzar un cirurgià dentista (k=0,998). Per al tractament estadístic es van calcular freqüències i percentatges, i la prova de khi quadrat corregida de Yates. Resultats: La condició clínica més freqüent va ser l'absència d'espais fisiològics (62,3%); així mateix, l'MT va tenir una distribució variable per sexe, prò no significativa. Es va observar associació entre l'MT amb l'absència d'espais fisiològics, l'hàbit de respiració bucal, la lactància i la mossegada profunda (X 2 Y =10,311, p =0,0001; X 2 Y =7,290, p=0,0001; X 2 Y =21,374, p =0,0001; X2 Y =8,127, p =0,044, respectivament), però no amb la succió digital. Conclusions: Els resultats d'aquest estudi posen de manifest el paper rellevant del pediatre per recomanar a les mares que alletin els seus fills durant un període no menor a sis mesos, així com la responsabilitat d'identificar i eradicar les causes que provoquen que l'infant respiri per la boca, a més de fer la derivació a l'odontopediatre en el cas que ho consideri necessari, perquè elimini aquest hàbit, com a mesura de prevenció per al desenvolupament de maloclusions dentals


Fundamento: El micrognatismo transversal (MT) es una alteración del crecimiento óseo y de la relación dentaria que impiden el funcionamiento adecuado del aparato masticatorio. Objetivo: Evaluar si existe asociación entre la frecuencia de MT con la lactancia materna menor a seis meses, la presencia de hábitos de succión digital, la respiración bucal y la ausencia de espacios fisiológicos. Método: Se llevó a cabo un estudio transversal examinando a 273 niños mexicanos de cinco años, de ambos sexos. Previamente a la encuesta, se estandarizó a un cirujano dentista ( k =0,998). Para el tratamiento estadístico fueron calculados frecuencias y porcentajes, y la prueba de ji cuadrado corregida de Yates. Resultados: La condición clínica más frecuente fue la ausencia de espacios fisiológicos (62,3%); asimismo, el MT tuvo una distribución variable por sexo, pero no significativa. Se observó asociación entre el MT con la ausencia de espacios fisiológicos, el hábito de respiración bucal, la lactancia y la mordida profunda (X 2Y=10,311, p=0,0001; X2Y=7,290, p=0,0001; X2Y=21,374, p=0,0001; X2Y=8,127, p=0,044, respectivamente), pero no con la succión digital. Conclusiones: Los resultados del resente estudio ponen de manifiesto el papel relevante del pediatra para recomendar a las adres que amamanten a sus hijos durante un periodo no menor a seis meses, así omo la responsabilidad de identificar y erradicar las causas que provocan que el niño espire por la boca, además de su derivación al odontopediatra en el caso de que lo onsidere necesario, para que elimine este hábito como medida de preven-ción para el esarrollo de maloclusiones dentales


Background: Transversal micrognathia (TM) is an alteration of bone growth and the dental distribution that affects the adequate function of masticatory apparatus. Objective: To evaluate the association between the frequency of transversal micrognathia and breastfeeding less than six months, the presence of thumb sucking habits, oral breathing, and the absence of physiological spaces. Method: We conducted a transversal study including 273 five- years-old Mexican children of both sexes. Prior to the survey, we standardized the evaluation by a dental surgeon ( k=0.998). We calculated frequencies and percentages, and applied the chi-squa-red test with Yates correction. Results: The most frequent clinical condition found was the absence of physiological spaces (62.3%). TM had a variable but not significant sex distribution. We observed an association between TM and the absence of physiological spaces, oral breathing, breastfeeding, and deep biting (X2Y=10,311, p=0,0001; X2Y=7,290, p=0,0001; 2Y=21,374, p=0,0001; X2Y=8,127, p=0,044, respec-tively), but not with thumb sucking. Conclusions: Our results highlight the relevant role of the pediatrician in advising others that breastfeed their children for periods shorter than six months, as well as the esponsibility to identify and eradicate the factors that cause oral breathing and rompt evaluation by a pediatric dentist when required to prevent the de-velopment of dental malocclusion

RESUMO

Introducción: en hallazgos cefalométricos de diferentes países en poblaciones con patrones de crecimientos y oclusión normal, se reportan diferencias estadísticamente significativas a los valores dados en los cefalogramas de Ricketts, Steiner, Downs, Jarabak y otros. En Cuba no existen estudios de estos patrones en niños con dentición mixta los que favorecerían un mejor diagnóstico de las anomalías dento-maxilofaciales. Objetivo: proponer el perfeccionamiento de las normas del cefalograma resumido de Ricketts para los niños. Materiales y Métodos: investigación observacional, descriptiva en cuatro poblaciones pertenecientes a las siguientes zonas del país: Matanzas, Cárdenas, Camagüey y Sancti Spíritus. El universo estuvo constituido por 1 657 niños de 9 años de edad. La muestra 163 niños, seleccionados por el método estratificado por conglomerados con oclusión dentaria normal. Se utilizó el análisis del cefalograma resumido de Ricketts y la prueba t de media para determinar los valores de las variables estudiadas y se hicieron estimaciones puntuales y por intervalos de confianza. Resultados: tres variables mostraron medias iguales a las normas de Ricketts: eje facial (90°), profundidad facial (87°) y profundidad maxilar (90°). En las restantes fueron comprobadas diferencias significativas. Se obtuvo un intervalo de confianza para cada una de las variables del cefalograma resumido de Ricketts. Conclusiones: solamente tres variables presentaron valores similares a los planteados por Ricketts, las restantes presentaron valores que difieren significativamente de los planteados por Ricketts. Se propone utilizar el intervalo de confianza obtenido en esta investigación en las variables del cefalograma resumido de Ricketts para diagnosticar las anomalías dento-maxilofaciales en niños cubanos (AU).


Introduction: in cephalometric findings from different countries in populations with normal growing and occlusion patterns, significant statistic differences are reported in relation to the values given in the cephalograms of Ricketts, Steiner, Downs, Jarabak, and others. In Cuba there are not studies of these patterns in children with mixed dentition that might allow a better diagnosis of dental, maxilla-facial anomalies. Objective: to propose the improvement of the standards of the Ricketts abridge cephalogram for children. Materials and methods: descriptive, observational research in four populations belonging to different regions of the country: Matanzas, Cárdenas, Camagüey and Sancti Spíritus. The universe was formed by 1675 children aged 9 years old; the sample, 163 children with normal dental occlusion, was chosen by the stratified method per conglomerate. The analysis of the Ricketts summarized cephalogram and the mean T test were used to determine the values of the studied variables; punctual estimates and estimates by confidence interval were carried out. Results: three variables showed equal means than Ricketts' standards: facial axis (90o), facial depth (87o) and maxillary depth (90o). In the remaining variables there were found significant differences. A confidence interval was obtained for every one of the Ricketts' summarized cephalogram variable. Conclusions: only three variables showed values similar to those given by Ricketts. The remaining ones presented values significantly differing from those established by Ricketts. The proposition is using the confidence interval obtained in this research in the variables of the Ricketts' summarized cephalogram to diagnose the dental-maxillafacial anomalies in Cuban children (AU).

RESUMO

PURPOSE: The present study evaluated electromyographic activity (EMG), masticatory performance, and tongue strength in children without and with orthodontic treatment needs. PATIENTS AND METHODS: A total of 90 children were screened and divided into the following groups: Group I (no treatment needed; mean age: 8.00 ± 0.43 years; n = 26), Group II (few malocclusions, treatment needed; mean age: 8.89 ± 0.43 years; n = 28), and Group III (slight-to-borderline treatment needed; mean age: 8.44 ± 0.22 years; n = 36). Orthodontic treatment need was classified on the basis of IOTN-DHC (Index of Orthodontic Treatment Need - Dental Health Component). The electromyographic Trigno EMG Systems was used for muscle analysis and the Iowa Oral Pressure Instrument (IOPI) was used to measure tongue strength. Data were analyzed using normality tests and one-way analysis of variance with a Bonferroni post hoc test (p ≤ 0.05). RESULTS: EMG in almost all mandibular movements was higher in Group III with statistically significant differences compared to position at rest: right masseter (p = 0.03); protrusion: left temporal (p = 0.02); saliva swallowing: left temporal (p = 0.05) and water swallowing: orbicularis oris mouth, right upper segment (p = 0.05). Lower masticatory performance was found in Group III, but the difference compared to Group I and II was not significant. There were no significant differences between the groups in terms of tongue strength. CONCLUSIONS: Children with borderline orthodontic treatment needs show functional disorders of the stomatognathic system.

RESUMO

According to epidemiological data, muscular dysfunctions of the masticatory system occur in 15-23% of the population. Preventive examinations of functional disorders of the stomatognathic system are, therefore, of particular importance. A distinct group of patients exposed to dysfunctions in the area of the masticatory organ locomotor apparatus comprises those with genetic diseases characterised by disorders in collagen formation. One of such diseases is osteogenesis imperfecta (OI) and dentinogenesis imperfecta that usually goes together with the former. AIM: The objective of this work was to evaluate the frequency with which particular disorders of the masticatory organ locomotor apparatus occur within the group of patients with osteogenesis imperfecta. MATERIAL AND METHODS: The study was performed on patients of the Orthopaedic Clinic of the Polish-American Paediatric Institute in Kraków. The mean age of the children was 7.9 years. In all the cases, a genetic diagnosis of OI has been confirmed. The research methods were based on an in-depth interview on family diseases, pregnancy, postnatal period, feeding, subjective assessment of dysfunctions in the stomatognathic system. An examination of the deformations in the stomatognathic system and the skeleton was conducted, as well as an examination of the trauma and tone of the jaw. The relationship between breastfeeding and swallowing and speech disorders was also evaluated. The impact of intubation on mandibular ranges was investigated. RESULTS: The results obtained were subjected to statistical analysis on the basis of which conclusions were drawn concerning disorders in the stomatognathic system which tend to occur in children with OI. The renunciation of breastfeeding significantly contributes to sucking and swallowing disorders, rumen disorders, as well as biomechanical disorders in the temporomandibular joint. A significant dependence between breastfeeding and swallowing problems was found, whereas there was no such dependence with respect to speech impediments. CONCLUSIONS: The results of the research conducted led to the following conclusions: 1. Among pediatric patients with OI there are disorders in the stomatognathic system. The most common dysfunctions are: abdominal, swallowing and sucking disorders, abnormal muscle structure of the rumen and biomechanical disorders in the temporomandibular joints. Breastfeeding significantly contributes to swallowing disorders. 2. The therapeutic process involving children with OI requires the cooperation of specialists in orthopedics, pediatrics, physiotherapy, orthodontics and neurologopedics to carry out comprehensive diagnostics and treatment tailored to the individual needs of the patient. 3. In order to draw final conclusions, there is a need for more research by means of objective tools, such as EMG and a condensate recorder.

RESUMO

The aim of this study is to investigate the biomechanics for orthodontic tooth movement (OTM) subjected to concurrent single-tooth vibration (50Hz) with conventional orthodontic force application, via a clinical study and computational simulation. Thirteen patients were recruited in the clinical study, which involved distal retraction of maxillary canines with 1.5N (150g) force for 12weeks. In a split mouth study, vibration and non-vibration sides were randomly assigned to each subject. Vibration of 50Hz, of approximately 0.2N (20g) of magnitude, was applied on the buccal surface of maxillary canine for the vibration group. A mode-based steady-state dynamic finite element analysis (FEA) was conducted based on an anatomically detailed model, complying with the clinical protocol. Both the amounts of space closure and canine distalization of the vibration group were significantly higher than those of the control group, as measured intra-orally or on models (p<0.05). Therefore it is indicated that a 50Hz and 20g single-tooth vibration can accelerate maxillary canine retraction. The volume-average hydrostatic stress (VHS) in the periodontal ligament (PDL) was computationally calculated to be higher with vibration compared with the control group for maxillary teeth and for both linguo-buccal and mesial-distal directions. An increase in vibratory frequency further amplified the PDL response before reaching a local natural frequency. An amplification of PDL response was also shown to be induced by vibration based on computational simulation. The vibration-enhanced OTM can be described by mild, vigorous and diminishing zones among which the mild zone is considered to be clinically beneficial.

RESUMO

Tessier facial clefts are among the rarest facial clefts reported in literature and many contradicting issues have always been rising over the management and surgical approaches involved during the craniofacial cleft repair. Among the craniofacial clefts Tessier no. 4 is an extremely rare facial anomaly, and there are very few evidence which clearly describe the surgical approaches and techniques. Often these type of craniofacial clefts yield very poor surgical results, and they require multidisciplinary sequential corrective surgeries. This article presents a rare case of an 18-month-old baby with bilateral Tessier no. 4 clefts and its successful rehabilitation.

RESUMO

Steinert syndrome, also called myotonic dystrophy type 1, is a genetic disorder with autosomal dominant transmission characterized by myotonia and a multisystemic clinical picture that affects several tissues of the human body. The most common systemic phenotypes are: muscular, cardiac, respiratory, CNS, ocular, gynecological, digestive, orthopedical, as well as cognitive and psychological symptoms (cognitive decline). Muscles involved in voluntary movement are highly affected by myotonia especially distal muscles of upper limbs. These patients also show changes in face, chewing and pharynx muscles that can lead to swallowing and speech problems, dysphagia and in most cases to food aspiration and suffocation. Poor oral hygiene resulting from reduced motor mobility and reduced saliva flux can lead to gingival inflammation and periodontal disease. Other oral manifestations include disturbances at the temporomandibular articulation, dental occlusion changes and reduction in teeth number as a result of caries. Main causes of death are pneumonia and cardiac arrhythmias. The etiopathogeny of this syndrome is still not clear, conditioning the existence of a specific treatment for this disease. Nowadays, treatments consist on the release of the existing symptoms, in an attempt to give a better life quality to patients. It is very important to implement actions that can prevent complications and consequently decrease death. Treatments should be applied in an early stage of the disease. Bronchoscopy and artificial respiration should be used to prevent pneumonia, and regular electrocardiographic monitoring should be done to evaluate defects in the conductive system. Several approaches have been applied to rehabilitate swallowing dysfunction and avoid aspiration like videofluoroscopy, postural techniques and adjustment of diet type. It is the aim of this paper to clarify the ethiology, diagnosis, systemic and oral characteristics of the syndrome, as well as to discuss treatments to be applied according to patients affected organs.

RESUMO

A Síndrome de Down é uma alteração genética congênita, autossômica com características craniofaciais ehipotonia muscular generalizada, o que propicia alterações dentoesqueléticas. O acompanhamentoortodôntico deve se estender desde o primeiro ano de vida até a fase a adulta, com monitoramento e correçãoconstantes de anormalidades funcionais que apareçam durante desenvolvimento e maturação das estruturasdentais e esqueléticas. O objetivo deste trabalho foi abordar as características craniofaciais dos portadores deSíndrome de Down, as más oclusões mais frequentes nesses pacientes e as opções terapêuticas ortodônticas eortopédicas que possam ser utilizadas. Desmistificando a atuação do Ortodontista na promoção de bem-estarfísico e social desse público. Realizou-se levantamento bibliográfico de artigos indexados nas bases de dadosSciELO e PubMed, publicados no período de 2012 a 2015. Por meio de estratégia de busca com base nostermos em português: Síndrome de Down, Ortodontia interceptativa, Má oclusão, Angle Classe III, Qualidadede vida. Em inglês: Down Syndrome, Orthodontics interceptive, Malocclusion, Angle Class III, Quality of Life.Podemos concluir com este trabalho que a interceptação ortodôntica e ortopédica nesses pacientes trazbenefícios como adequação da função, da estética e da qualidade de vida


Down syndrome is a congenital, autosomal genetic disorder associated with craniofacial features andgeneralized muscular hypotonia, which lead to dental and skeletal changes. There must be orthodonticmonitoring from the child’s first year of life up to his/her adulthood to constantly monitor and correctfunctional abnormalities that may occur during the development and maturation of dental and skeletalstructures. The aim of the current study is to address the craniofacial features of Down syndrome patients,their most common malocclusions, as well as the orthodontic and orthopedic treatment options that may beused to demystify the Orthodontist performance by providing physical and social well-being to these patients.We conducted a literature review on articles indexed to databases such as SciELO and PubMed, publishedbetween 2012 and 2015. The search was based on the following meshes in Portuguese: Síndrome de Down;Ortodontia interceptativa; Má oclusão, Angle Classe III; Qualidade de vida (in English: Down syndrome;Interceptive Orthodontics; Malocclusion, Angle Class III; Quality of life). We concluded that the orthodontic andorthopedic interceptive treatment is beneficial to these patients since it allows adjusting function, aestheticsand quality of life

RESUMO

Introdução: resultados estéticos na cirurgia ortognática são um dos principais objetivos dos pacientes, ortodontistas e cirurgiões. A correção da deformidade óssea maxilomandibular, geralmente, restabelece as funções do sistema estomatognático e a estética facial. No entanto, nem sempre obtém-se simetria e projeção desejada dos tecidos moles somente com a movimentação óssea. Nesse sentido, o preenchimento com o polimetilmetacrilato (PMMA) atua como coadjuvante na tentativa de se obter contornos faciais que alcancem as expectativas estéticas dos pacientes e profissionais. Objetivo: o presente artigo revisa a utilização do metilmetacrilato como material de preenchimento na região craniofacial, abordando a sua perspectiva histórica, vantagens e aspectos biológicos. As principais indicações são ilustradas com figuras e casos clínicos

RESUMO

PURPOSE: The objective of this case series was to determine the oral, dental and craniofacial features of patients with EvC syndrome. MATERIAL AND METHODS: Eight patients with EvC syndrome were enrolled. A complete family history, pedigree analysis, detailed medical history were collected. Findings of clinical examination, including craniofacial and orodental manifestations, and radiological investigations were thoroughly studied. RESULTS: All eight patients had characteristic face, hypertrophic frenulum, conical and peg-shaped teeth, hypodontia of deciduous and/or permanent teeth and also skeletal dysplasia, small chest, short stature and hypoplastic nails. Additionally dysmorphic filtrum, serrated appearance of gingiva, diastema, enamel hypoplasia, microdontia, taurodontism, single rooted permanent molar, delayed eruption and high caries rate were observed with varying degrees. Cephalometric evaluation revealed skeletal Class III growth pattern in four subjects and Class II growth pattern in one subject. CONCLUSION: Evaluation of craniofacial and orodental anomalies of EvC syndrome is required for accurate differential diagnosis from other congenital syndromes.
