RESUMO

Los dientes supernumerarios son unidades dentales que numéricamente exceden la cantidad de dientes normal, un fenómeno también conocida como hiperdontia, los dientes supernumerarios más comunes son mesiodens, que ocurren entre los incisivos centrales. El presente artículo tiene como objetivo describir un reporte de caso de una paciente de género femenino, de 21 años de edad, que presenta 13 dientes incluidos, de los cuales 6 son supernumerarios, los mismos que fueron extraídos en dos tiempos quirúrgicos. (AU)


Supernumerary teeth are dental units that numerically exceed the normal number of teeth, a phenomenon also known as hiperdontia. The most common supernumerary teeth are mesiodens, which occur between the central incisors. This article aims to describe a case report of a female patient, 21 yearsold, who has 13 included teeth, of which 6 are supernumerary, thesameones that were extracted in two surgical times. (AU)

RESUMO

La mucopolisacaridosis tipo IV (MPS-IV) también conocida como enfermedad de Morquio en recuerdo del pediatra uruguayo Luis Morquio que la describió por primera vez, es una enfermedad congénita causada por la deficiencia de la enzima N-acetilgalactosamina 6 sulfatasa o de la enzima B-Galactosidasa. Estas anomalías enzimáticas tienen como consecuencia que se acumulen en diferentes tejidos del organismo cantidades elevadas de mucopolisacaridos. En la bibliografía se describe con detalle los defectos del esmalte que presentan los pacientes diagnosticados del síndrome de Morquio. Estos defectos son una característica aparentemente constante en la enfermedad y, por lo tanto, hace necesaria las visitas al odontólogo para su control evitándose problemas mayores. Dichos defectos consisten en un esmalte anormalmente delgado, que es áspero debido a los numerosos hoyos diminutos y a una superficie irregular. La delgadez del esmalte da como resultado una forma alterada y decoloración de los dientes que, añadido a los diastemas interdentales, provocan alteraciones en la oclusión. Aparte de estos defectos, el esmalte es histológicamente normal y tiene una du-reza y radiodensidad normales. El trata-miento odontológico de los pacientes con MPS-IV requiere colaboración multidisciplinar, debido a que las manifestaciones orales de la enfermedad pueden aparecer a cualquier edad, resultando en ocasiones tedioso para el paciente y complicado para el profesional. Especial mención merecen las terapias utilizadas como trata-miento sintomático de la enfermedad, así como el manejo de la vía aérea en el caso de intervenciones bajo anestesia general o sedación para tratar ciertas patologías del territorio bucomaxilodental


Mucopolysaccharidosis type IV (MPS-IV) also known as Morquio’s disease in memory of the Uruguayan pediatrician Luis Morquio who described it for the first time, is a congenital disease caused by the deficiency of the enzyme N-acetylgalactosamine 6 sulfatase or enzyme B -Galactosidase. These enzymatic anomalies result in high amounts of mucopolysaccharides accumulating in different tissues of the organism. The enamel defects presented by patients diagnosed with Morquio syndrome are described in detail in the bibliography. These defects are an apparently constant feature in the disease and, therefore, make visits to the dentist necessary for their control, avoiding major problems. These defects consist of an abnormally thin enamel that is rough due to numerous tiny holes and an irregular surface. The thinness of the enamel results in an altered form and discoloration of the teeth, which added to the interdental diastemas, cause alterations in the occlusion. Apart from these defects, the enamel is histologically normal and has a normal hardness and radiodensity.Dental treatment of patients with MPS-IV requires multidisciplinary collaboration, because the oral manifestations of the disease can appear at any age, being sometimes tedious for the patient and complicated for the professional. Special mention should be made of the therapies used as a symptomatic treatment of the disease, as well as the management of the airway in the case of interventions under general anesthesia or sedation to treat certain pathologies of the bucomaxillodental territory

RESUMO

Las malformaciones dentales son defectos formativos causados por alteraciones genéticas durante la morfogénesis den-tal. Pueden ser provocados por factores de índole hereditario, sistémico, traumático o local. Dentro de estas anomalías se encuentra el taurodontismo. Éste se caracteriza por presentar una alteración de la morfología dentaria en la que la porción coronaria del órgano dentario se encuentra alargada con una cámara pulpar ensanchada, a expensas de la porción radicular, disminuyendo la longitud y por tanto, produciéndose una migración apical de la furca del diente. El objetivo del presente artículo es describir las anomalías de forma dentaria y más concretamente el manejo clínico del paciente con taurodoncia en la clínica dental. Para ello se presenta el caso clínico de un paciente de 18 años de edad que acude al Hospital Universitario de la Princesa de Madrid para valorar la exodoncia de dos molares localizados en el primer y cuarto cuadrante. Tras un diagnóstico clínico y radiológico apropiado, se procedió a la exodoncia de los mismos


Dental anomalies are formative defects caused by genetic disturbances during tooth morphogenesis, can be caused by factors of a hereditary, systemic, traumatic or local nature. One such anomaly is taurodontism. It is characterized by pulp chamber enlargement, which may approximate of the root apex, with the body of the tooth enlarged at the expense of the roots and apically displaced furcation areas.The aim of this case report is to describe the abnormalities of tooth shape and particularly the management in the dental clinic of patients with taurodontism. For this purpose a case of a eighteen years patient visiting the Hospital Universitario de la Princesa of Madrid to assess the extraction of two molars located in the first and fourth quadrants. After a proper clinical and radiological diagnostic we proceeded to the extraction

RESUMO

Background: To evaluate oral, craniofacial and systemic characteristics of eight patients with Kabuki syndrome (KS), aged between 3 and 16 years old. Material and Methods: in this retrospective study, medical records of all patients were reviewed for information on family history, growth and development, medications in use, general systemic complications and oral and craniofacial characteristics. Results: the medical alterations found included recurrent infections such as pneumonia and otitis media (n = 6), cardiovascular malformations (n = 4), kidney abnormalities (n = 2), epilepsy (n = 2) and visual deficiency (n = 2). The individuals exhibited dental caries (n = 5), agenesis (n = 5), delayed tooth eruption (n = 4), cleft lip/palate (n = 2) enamel hypoplasia (n = 2), fusion (n = 1) and microdontia (n = 1). Conclusions: There was a great diversity of oral, craniofacial and systemic characteristic among the KS patients, suggesting that an inter-disciplinary approach should be taken for their dental treatment

RESUMO

Background: The aim of this study was to record and analyze all DDAs associated to dilacerated teeth in patients attending the clinics of the Postgraduate Division, Facultad de Odontología, UNAM in Mexico City. Material and Methods: Orthopantomograms from all patients seeking for stomatological attention in our institution were reviewed and those cases of dilaceration were separated. Age, gender, diagnosis, location, involved teeth and associated DDAs were recorded and analyzed. Results: From 6,340 patients, 99 (1.6%) harbored 125 dilacerated teeth. Of them, 45 (45.5%) showed one or more DDAs. The most frequently detected DDAs were hypodontia, enamel pearls, taurodontism and microdontia. Conclusions: 45.5% is a very high proportion of DDAs in patients with dilacerated roots. Findings from this study strongly suggest that patients with dilacerated teeth should be carefully screened since many of them could present other DDAs. Simultaneous occurrence of dilaceration and DDAs suggests synchronic developmental defects during dental growth

RESUMO

La hipomineralización de incisivos y molares es un trastorno de desarrollo de los primeros molares y de los incisivos permanentes. El esmalte afectado es frágil y se puede desprender fácilmente, dejando expuesta la dentina, lo cual favorece la sensibilidad dentinaria y el desarrollo de lesiones cariosas. Los posibles factores etiológicos se asocian a alteraciones durante la gestación y a algunas enfermedades de la primera infancia. Los pacientes afectados por hipomineralización de incisivos y molares exhiben signos y síntomas clínicos definidos, lo que permite clasificarlos de acuerdo con la gravedad y con las características de la hipomineralización. El tratamiento de los niños afectados por hipomineralización de incisivos y molares debe ir dirigido, en primer lugar, al diagnóstico de las lesiones y al establecimiento del riesgo de caries. Cuando se presenten molares con ruptura del esmalte y exposición dentinaria, se debe emplear un manejo integral con control de la conducta y la ansiedad, con el objetivo de ofrecer a los pacientes un tratamiento sin dolor que permita la restauración y el mantenimiento de una salud bucal adecuada, por lo que es importante establecer medidas de control de la caries


The hypomineralization of the incisors and molars is a developmental enamel defect affecting one to four permanent first molars frequently associated with affected incisors. The enamel breakdown is common in the affected mo lars resulting in hypersensitivity and to dental caries development. The possible etiological factors are as sociated with systemic cause occurring in pregnancy, around the time of birth or in the first childhood. The treatment of children affected by molar-incisor hypomineralization should be focused, first, on the diagnosis of the lesions and the establishment of caries risk. A comprehensive management of behavior and anxiety should be offered in patients with enamel cracks and exposed dentin in molars, in order to offer a painless treatment with long life restorations and proper oral health maintenance. It is also important to establish caries control procedures

RESUMO

El taurodontismo es una anomalía del desarrollo que afecta a la morfología del tejido pulpar. Los dientes con esta alteración, presentan una amplia cámara pulpar en sentido ocluso-apical más allá de la unión amelocementaria. El objetivo de este artículo es describir de forma sintetizada y actualizada los métodos biométricos que pueden ser utilizados en el diagnóstico de taurodontismo en dentición permanente. Éstos nos permiten determinar no sólo la presencia de taurodontismo sino también el grado en el que esta alteración puede presentarse (hipertaurodontismo, mesotaurodontismo e hipotaurodontismo). A pesar de la evolución que han experimentado a lo largo del siglo pasado, la principal desventaja que presentan estas valoraciones métricas en la actualidad, es la dificultad para localizar los puntos de referencia de una forma reproducible sobre radiografías panorámicas (AU)


Taurodontism is a developmental anomaly that affects the morphology of the pulp tissue. The teeth with this alteration, present a large pulp chamber in occlusal-apical sense beyond the amelocementary union. The objective of this article is to describe in a synthesized and updated way the biometric methods that can be used in the diagnosis of taurodontism in permanent dentition. These allow us to determine not only the presence of taurodontism but also the degree to which this alteration can occur (hypertaurodontism, mesotaurodontism and hypotaurdontism). In spite of the evolution that they have undergone during the last century, the main disadvantage that present these metric valuations at present, is the difficulty to locate the points of reference of a reproducible form on panoramic radiographs (AU)

RESUMO

Introducción. Algunos pacientes con labio y paladar hendido presentan anomalías dentales, principalmente aquellas que incluyen anomalías de número, como, por ejemplo, el diente supernumerario. El diagnóstico y tratamiento son importantes, ya que ayudan a minimizar problemas funcionales y estéticos. Objetivo. Determinar la prevalencia de dientes supernumerarios mediante el análisis radiográfico, en la población con labio y paladar hendido que asiste al Hospital Nacional de Niños (Costa Rica), durante el período agosto de 2009 - julio de 2010. Metodología. El estudio se basó en escoger un expediente de cada 4 pacientes de la consulta externa, con el fin de revisar este y analizar la ortopantomografía. Las técnicas estadísticas para el análisis fueron las distribuciones de frecuencia, cruce de variables, comparación de medias con base en el análisis de variancia. El nivel mínimo de confianza para las comparaciones fue del 95%. Resultados. La muestra total comprendió 180 expedientes con una confianza del 95% y un error máximo permisible del 5%. Un 32% de la población presentó dientes supernumerarios; destacándose el grupo de pacientes con hendidura labial, alveolar y palatina. Los dientes supernumerarios se localizaron en un 100% a nivel maxilar, con el diente ubicado dentro de la zona de la hendidura principalmente (77%), específicamente en la región del canino (51%). Conclusiones. El diente supernumerario es una anomalía que se presenta en los pacientes con labio y paladar hendido, por lo que es pertinente el buen diagnóstico clínico y radiográfico para determinar su presencia, y así escoger la más apropiada opción de tratamiento según las necesidades del caso (AU)


Introduction. Patients with cleft lip and palate usually have dental abnormalities, particularly supernumerary tooth anomalies. The diagnosis and treatment are important, since it helps to minimise functional and aesthetic problems. Objective. The purpose of this study was to determine the prevalence of supernumerary teeth by radiographic analysis in patients with cleft lip and palate, who were treated in the Hospital Nacional de Niños, Costa Rica, during the period August 2009-July 2010. Methodology. The study was based on choosing a record of every 4 patients of the outpatient department, in order to review and analyse the orthopantomography. The statistical techniques used were frequency distributions, cross variables, and comparison of means based on the analysis of variance. The minimum level of confidence for comparisons was 95%. Results. The total sample comprised 180 records with a confidence of 95% and a maximum permissible error of 5%. Almost one-third (32%) of the population had supernumerary teeth, particularly the group of patients with cleft lip, alveolar and palate. Supernumerary teeth were 100% located on the maxillary arch, and mainly within the area of the alveolar cleft (77%), specifically in the region of the canine (51%). Conclusion. The supernumerary tooth is an anomaly that occurs with cleft lip and palate, so a good clinical and radiographic diagnosis is important to determine its presence, and thus to choose the most appropriate treatment option according to the needs of the case (AU)

RESUMO

El objetivo de este trabajo es realizar una revisión bibliográfica que actualice y englobe todos los factores etiológicos locales y generales de la inclusión de los segundos molares mandibulares. Se define como inclusión dentaria al proceso patológico eruptivo por el que el diente se encuentra rodeado de saco pericoronario, conservando su lecho óseo intacto y produciendo su ausencia en la arcada dentaria. Si bien este fenómeno es bastante frecuente en algunos grupos dentarios como los terceros molares, caninos superiores y/o premolares inferiores, la inclusión del segundo molar, con una prevalencia próxima al 0,03-0,21%, resulta todavía un desafío tanto para cirujanos orales como para ortodoncistas. Para la prevención de este tipo de alteraciones son necesarias revisiones periódicas durante el inicio del periodo de transición dentaria para así poder detectar algún tipo de anomalía eruptiva y realizar un tratamiento precoz ortodóntico. El factor local que más condiciona a este tipo de patología parece ser la falta de espacio, mientras que las anomalías genéticas serían las responsables principales de producir la inclusión del segundo molar desde el punto de vista sistémico y general según los estudios más recientes (AU)


The objective was to perform a literature review that updates the local and general etiological factors of the inclusion of the second molars. It is defined as dental inclusion to the pathological eruptive process by which tooth is surrounded by pericoronal sack, preserving its bone bed intact and producing his absence in the dental arch. Though this phenomenon is quite common in some groups of teeth as third molars, upper canines or lower premolars, the inclusion of the second molar, with a prevalence next to 0,03- 0,21%, it turns out to still being a challenge for oral surgeons and for orthodontists. For the prevention of this type of alterations, periodic check-ups are necessary during the beginning of the dental transition period in order to detect some type of eruptive anomaly and to perform an early orthodontic treatment. The local factor that most affects this type of pathology seems to be the lack of space, while genetic abnormalities would be the main responsible for producing the inclusion of the second molar from the systemic and general point of view according to the most recent studies (AU)

RESUMO

BACKGROUND: An eruption cyst (EC) is a benign, developmental cyst associated with a primary or permanent tooth. This paper presents 66 ECs in 53 patients who reported to 3 different centers in Turkey between 2014-2015. MATERIAL AND METHODS: 53 patients (31 male, 22 female) with 66 ECs were diagnosed and treated over a 1-year period. The mean age of patients was 5.4 years (minimum 5 months, maximum 11 years). Clinical examination and periapical radiographs were used to establish diagnosis. Age, gender, site, history of trauma and type of treatment were recorded. RESULTS: Of the 66 ECs diagnosed in 53 patients, more than half (56.6%) were located in the maxilla, with the maxillary first primary molars the teeth most commonly associated with ECs (30.3%). Multiple ECs were diagnosed in 13 of the 53 patients. ECs had previously diagnosed in the primary dentition of 2 patients, 3 patients reported a history of trauma to primary teeth. In the majority of patients (46 cases, 86.8%), no treatment was provided, whereas surgical treatment was provided in the remaining 7 cases (13.2%). CONCLUSIONS: Eruption cysts are usually asymptomatic and do not require treatment;. however, if the cyst is symptomatic, it should be treated with simple surgical excision

RESUMO

BACKGROUND: The prevalence of impacted maxillary canine is reported to be between 1% and 3%. The lack of monitoring and the delay in the treatment of the impacted canine can cause different complications such as: displacement of adjacent teeth, loss of vitality of neighbouring teeth, shortening of the dental arch, follicular cysts, canine ankylosis, recurrent infections, recurrent pain, internal resorption of the canine and the adjacent teeth, external resorption of the canine and the adjacent teeth, combination of these factors. An appropriate diagnosis, accurate predictive analysis and early intervention are likely to prevent such undesirable effects. The objective is to evaluate, by means of a retrospective observational study, the possibility of carrying out a predictive analysis of root resorption adjacent to the impacted canines by means of orthopantomographs, so as to limit the prescription of additional 3D radiography. MATERIAL AND METHODS: 120 subjects with unilateral or bilateral maxillary impacted canine were examined and 50 patients with 69 impacted maxillary canine (22 male, 28 female; mean age: 11.7 years) satisfied the inclusion criteria of the study. These patients were subjected to a basic clinical and radiographic investigation (orthopantomographs and computerized tomography). All panoramic films were viewed under standardized conditions for the evaluation of two main variables: maxillary canine angulations (a, b, g angles) and the overlapping between the impacted teeth and the lateral incisor (Analysis of Lindauer). Binary logistic regression was used to estimate the likelihood of resorbed lateral incisors depending on sector location and angle measurements. RESULTS: Results indicated that b angle has the greatest influence on the prediction of root resorption (predictive value of b angle = 76%). If β angle <18° and Lindauer = I, the probability of resorption is 0.06. CONCLUSIONS: Evaluation of b angle and superimposition lateral incisor/impacted canine analysed on orthopantomographs could be one of the evaluation criteria for prescribing second level examination (CT and CTCB) and for detecting root resorption of impacted maxillary canine adjacent teeth

RESUMO

Los términos geminación y fusion dentaria son utilizados para describir dos anomalías dentarias por unión en las que se afectan el número, la estructura, la forma, y el tamaño dentario. Su diagnóstico diferencial es muy complicado, a pesar de los numerosos casos que se pueden encontrar en la literatura. Es por ello, que muchos autores denominan a este grupo de anomalías como «diente doble» o «diente gemelo», considerándolos así como términos sinónimos. El diagnóstico y tratamiento del «diente doble» es un desafío para el dentista, así como su nomenclatura. Debe llevarse a cabo un diagnóstico diferencial con la macrodoncia. Los dientes afectados representan frecuentemente un problema estético, siendo más susceptibles a la caries y a la enfermedad periodontal. Es necesario llevar a cabo un examen clínico y radiográfico exhaustivo, para obtener un diagnóstico correcto que permita alcanzar un tratamiento temprano, en caso de que sea necesario. La opción de tratamiento del «diente doble» depende del tipo de dentición afectada, la repercusión estética, la morfología del arco dental y el patrón de oclusión. Cuando se requiere tratamiento endodóncico, es obligatorio prestar más atención durante determinadas fases, especialmente en el diagnóstico radiológico, y en el acceso y localización de conductos. Este artículo discute la prevalencia, etiología, patogenia, diagnóstico diferencial y tratamiento del diente doble mediante cuatro casos clínicos


Gemination and fusion are terms used to describe two dental anomalies by union, where number, shape, structure and tooth size are affected. Differential diagnosis is complicated, in spite of numerous cases described in literature. Thereby, many authors describe this group of anomalies as «double teeth» or «twin-teeth», considering them as synonymous terms. «Double teeth» diagnosis and treatment are a challenge for dentist, as well as its nomenclature. Differential diagnosis with macrodontia must be carried out. Affected tooth frequently show poor aesthetic, being more susceptible to caries and periodontal disease. It is necessary to carry out an exhaustive clinical and radiographic examination to provide a correct diagnosis for achieving an early treatment, if necessary. Treatment choice in double-teeth depends upon the type of affected dentition, aesthetic involvement, dental arch morphology and occlusion pattern. When requiring endodontic treatment, more attention during certain stages, especially in diagnostic radiology, and in access, and location of roots canals are compulsory. This article discuss the prevalence, etiology, pathogenesis, differential diagnosis and treatment of double-teeth through four clinical cases

RESUMO

La concrescencia es una anomalía dentaria poco frecuente que se define como la unión de las raíces de dos dientes adyacentes a través del cemento. Aunque en la práctica clínica el término "concrescencia" es utilizado para referirse a todos los casos de unión entre las raíces de dos dientes adyacentes, para confirmar el diagnóstico de concrescencia es necesario un estudio histológico que demuestre la unión a nivel del cemento. Esta anomalía se ha identificado en el 0,8% de los casos de exodoncia de dientes permanentes, siendo su incidencia mayor en la región posterior del maxilar superior. La detección previa de la concrescencia mediante la exploración clínica y radiográfica es, la mayoría de las ocasiones, casi imposible, por lo que el diagnostico suele hacerse después de la extracción. No obstante, es conveniente que el clínico evalúe cada paciente y cada diente de forma exhaustiva para poder planificar, caso de que exista concrescencia, la técnica quirúrgica adecuada para la extracción. Por lo tanto, deben conocerse la incidencia e implicaciones de esta anomalía para llevar a cabo un diagnóstico y plan de tratamiento correcto. En este artículo se presenta un caso clínico de aparente concrescencia diagnosticado post-extracción y cuyo estudio histológico no mostró unión de cemento entre ambas raíces. Por lo tanto, en la práctica clínica es más conveniente utilizar el término "raíces fusionadas" que "concrescencia", el cual sólo debería ser utilizado después del examen histológico de la pieza extraída


Concrescence is a rare dental anomaly defined as the cemental union of two adjacent teeth. Concrescence diagnosis requires histological confirmation, but in the clinical practice the term "concrescence" is used to refer to all the cases of union of the roots of two adjacent teeth. The anomaly has been reported in extraction cases with an incidence of 0.8% in the permanent dentition. Also has been reported a higher incidence of concrescence in the posterior maxilla. It is prudent for the clinician to evaluate carefully each patient and each tooth to be removed for the possibility and desirability of a surgical extraction technique. Therefore, consideration should be given to the possible occurrence, recognition, and implications of this anomaly in diagnosis and treatment planning. Clinically and radiographically is nearly impossible to detect concrescent teeth, and most of these cases are diagnosed post extraction. The purpose of this article is to report a case of clinical concrescence between a retained third molar and an erupted second molar identified during the extraction, which histological study did not show cementum union between both roots. Thus, in the clinical practice is better to use the term "fused roots" than "concrescence", which would be used only after the histological examination of the specimen

RESUMO

BACKGROUND: The aim of this study was to know the distribution of dental developmental alterations in the population requesting stomatological attention at the Admission and Diagnosis Clinic of our institution in Mexico City. MATERIAL AND METHODS: We reviewed the archives and selected those files with developmental dental alterations. Analyzed data were diagnoses, age, gender, location and number of involved teeth. RESULTS: Of the 3.522 patients reviewed, 179 (5.1%) harbored 394 developmental dental alterations. Of them, 45.2% were males and 54.8% were females with a mean age of 16.7 years. The most common were supernumeraries, dental agenesia and dilaceration. Adults were 30.7% of the patients with dental developmental alterations. In them, the most common lesions were agenesia and supernumeraries. Mesiodens was the most frequently found supernumerary teeth (14.7%). CONCLUSIONS: Our finding that 30.7% of the affected patients were adults is an undescribed and unusually high proportion of patients that have implications on planning and prognosis of their stomatological treatment

RESUMO

La mayor prevalencia de anomalías del desarrollo de la forma que afectan parcialmente a la corona, se corresponden con la entidad conocida como cúspides accesorias o supernumerarias. Este término se refiere a la presencia de un mayor número de cúspides o a cúspides desproporcionadamente grandes, que alteran la anatomía normal del diente. Ambas pueden aparecer en cualquier grupo dentario. En la literatura están descritos, entre otros, los siguientes tipos: talón cuspídeo, cúspides centrales o intersticiales, tubérculos paramolares, tubérculo de Carabelli, diente evaginado, diente en tecla de piano, diente en destornillador o en clavija1. Algunas de estas anomalías son más que evidentes clínicamente, y otras pueden pasar desapercibidas para el profesional. No existen suficientes datos epidemiológicos para determinar la prevalencia de esta alteración en población infantil. Se desconocen las circunstancias que provocan esta anomalía de forma durante el desarrollo embrionario. Sin embargo, puede ser debida a la combinación de factores genéticos y ambientales que afectan a la actividad de la lámina dental durante la odontogénesis (AU)

RESUMO

Introducción: Los patrones de anomalías dentarias (PAD) son alteraciones de los dientes que se manifiestan asociadas con mayor frecuencia de lo que cabría esperar por azar. Incluyen diversas alteraciones morfológicas, numéricas y trastornos eruptivos que probablemente comparten una etiopatogenia genética común. Conocemos la prevalencia de la mayoría de las anomalías integrantes de los PAD consideradas aisladamente, pero no la correspondiente a la entidad compleja. Objetivo: Analizar la prevalencia de los PAD en los últimos 100 pacientes estudiados consecutivamente en la unidad de Ortodoncia del hospital universitario Fundación Jiménez Díaz (uO-FJD). Método: Se examinaron retrospectivamente las radiografías panorámicas y fotografías intraorales de los últimos 100 pacientes de ambos sexos, etnia caucásica y edades comprendidas entre 8 y 15 años diagnosticados consecutivamente en la uO-FJD. Se registraron las siguientes anomalías: hipodoncia, microformas aisladas, tamaño dentario reducido, retraso eruptivo, infraoclusión de molares temporales, desplazamiento palatino de los caninos, transposición (CPmSup o C-IlatInf), distoangulación del segundo premolar inferior no erupcionado y taurodontismo. La asociación de dos o más anomalías se denominó PAD 'sensu stricto' y la presencia confirmada de una sóla anomalía, 'posible PAD'. Resultados: La prevalencia de los PAD 'sensu stricto' fué 18% y 'posible PAD' 16%. La de ambos tipos conjuntamente, 34%. Conclusiones: La prevalencia de los PADs es muy alta. Todo clínico debe estar familiarizado con este concepto, ya que el diagnóstico de una anomalía debe hacer sospechar la posible existencia -o posterior desarrollo- de otras, en el paciente o sus familiares (AU)


Introduction: Dental Anomaly Patterns (PAD) are dental abnormalities that are observed together more frequently than can be explained by chance alone. They include morphologic and numeric abnormalities together with eruption disorders that likely have shared genetic origins. The prevalence of some of these isolated anomalies, as hypodontia, is well known but the literature does not record the frequencies of PAD considered as groups of interrelated concomitant abnormalities. Aim: To analyze the frequency of DAP in a sample of 100 orthodontic patients consecutively diagnosed at the unit of Orthodontics of hospital universitario Fundación Jiménez Díaz (uO-FJD). Method: Panoramic radiographs and intraoral photographs of 100 orthodontic consecutively evaluated patients were retrospectively examined in order to analyze the following abnormalities: hypodontia, microforms and tooth-size reduction, delayed tooth formation, infraocclusion of deciduous molars, palatal displacement of canine, dental transposition (Mx.C-P1 or Mn.I2-C), distal angulation of unerupted mandibular second premolar and taurodontism. Ages ranged from 8 to 15 years. The association of two or more abnormalities was named PAD 'sensu stricto'; the presence of one confirmed abnormality was named 'possible PAD'. The frequency of both PADs was determined. Results: The prevalence of PAD 'sensu stricto' was 18% and 'possible PAD' 16%. Considered together both groups, the frequency of PAD reached 34%. Conclusions: The prevalence of PADs is very high. All clinicians possibly involved must recognize that diagnosis because one anomaly may be a marker of other undiagnosed or later appearing abnormalities in the same patient or their siblings (AU)

RESUMO

BACKGROUND: Individuals with nonsyndromic cleft lip with or without cleft palate (NSCL±P) present high frequency of dental anomalies, which may represent complicating factors for dental treatment. The aim of this study was to investigate the prevalence of dental anomalies inside cleft area in a group of Brazilians with NSCL±P. MATERIAL AND METHODS: Retrospective analysis of 178 panoramic radiographs of patients aged from 12 to 45 years old and without history of tooth extraction or orthodontic treatment was performed. Association between cleft type and the prevalence of dental anomalies was assessed by chi-square test with a significance level set at pless than or equal to 0.05. RESULTS: Dental anomalies were found in 88.2% (n = 157) of the patients. Tooth agenesis (47.1%), giroversion (20%) and microdontia (15.5%) were the most common anomalies. Individuals with unilateral complete cleft lip and palate (CLP, p< 0.0001) were more affected by tooth agenesis than individuals with other cleft types. The maxillary lateral incisors were the most affected teeth (p < 0.0001). CONCLUSIONS: The present study revealed a high frequency of dental anomalies inside cleft region in NSCL±P patients, and further demonstrated that patients with unilateral complete CLP and bilateral incomplete CLP were frequently more affected by dental anomalies. Moreover, our results demonstrate that dental anomalies should be considered during dental treatment planning of individuals affected by NSCL±P
