ABSTRACT
AIM: This study was conducted to determine frequency, distribution and magnitude of infraocclusion in primary mandibular molars; to evaluate root resorption, the frequency of premolars agenesis and the association between primary molar infraocclusion and premolar agenesis. MATERIALS AND METHODS: The sample consisted of 472 children who were subdivided in 3 age groups. The magnitude of infraocclusion was determined following the Bjerklin and Bennett method modified by the authors. Radicular resorption was determined using the rating scale proposed by Bjerklin and Bennett evaluating mesial and distal roots separately. The development degree of corresponding premolars was determined using the Demirjian method. RESULTS: One hundred and three (21.8%) children presented infraocclusion. The first primary molar presented infraocclusion in a significantly higher frequency. Considering the 3 scores of infraocclusion, 61.1% of the affected molars were classified as mild infraocclusion. No differences were found considering the root resorption pattern for primary molars, infraoccluded or not. Significant differences were found in the presence of agenesis in the group of infraoccluded molars. CONCLUSION: The present study identified a high percentage of infraocclusion, demonstrating that the type of molar is an influent variable, that the first primary molar is the most affected one, especially mandibular molars, and that the majority was mainly of a mild degree. There were no significant differences between the exfoliation of infraoccluded and non infraoccluded primary molars. However, radicular resorption of infraoccluded molars presented a clear delay or was totally absent in infraoccluded molars associated with premolar agenesis. Significant differences in the presence of agenesis beneath infraoccluded molars were observed.

Introducción: El síndrome de Noonan es una enfermedad genética frecuente, caracterizada por corta estatura, cuello alado y deformidad torácica entre otras alteraciones. No existen reportes que mencionen complicaciones de la salud bucal. Se presentan tres niños con este síndrome en quienes se observó un cuadro de policaries severa, determinando en cada caso cuales fueron los factores que incrementaron su susceptibilidad a la caries. Casos clínicos:1. Niña de 4 años que cursó con sepsis neonatal, ectasia pielocalicial, hipertrofia congénita del píloro, cardiopatía, hipoacusia y retraso psicomotor. Tenía múltiples caries cavitadas, requiriendo extracción de 4 incisivos.2. Niño de 4 años que cursó con miocardiopatía, ectasia pielocalicial y retraso psicomotor. Mostraba múltiples caries cavitadas, de localización atípica; se extrajeron 4 incisivos y se colocaron coronas preformadas.3. Niño de 9 años que cursó con plagiocefalia, laringomalacia, hernia hiatal, infecciones urinarias y retraso psicomotor. Tenía múltiples caries, profundas y extensas. requiriendo tratamiento pulpar y colocación de coronas preformadas. Discusión: Las caries en los tres pacientes eran similares y de rápida progresión. Los factores más relevantes fueron: vómitos y reflujo en dos pacientes e ingesta continua y prolongada de zumos, en otro. En los tres hubo exposición anormal a ácidos intrínsecos o extrínsecos en la cavidad bucal, así como hipotonía muscular y déficit psicomotor que dificultaron la autoclisis y la higiene bucal. Se infiere que en todos la patología inicial fue un cuadro de desmineralización de origen químico concordante con erosión dentaria, sobre el que ocurrió una inmediata colonización de microorganismos, acelerando la destrucción de los tejidos. Se concluye que las condiciones sistémicas y familiares de niños con Síndrome de Noonan favorecen la erosión y la instauración de caries que son focos potencialmente nocivos, por lo que deben implantarse medidas preventivas adecuadas y prontas (AU)

Esta investigación tiene por objeto observar la evolución de la profundidad de arcada en una población española y su relación con la edad cronológica. Este método tiene la ventaja de facilitar la aplicación de los resultados obtenidos, así como su comprensión, ya que la aparición de determinados signos de maduración se asocian normalmente con la edad cronológica del individuo. Se realizaron medidas en 539 modelos obtenidos de una población de niños españoles entre los 6 y 14 años de edad. El análisis estadístico se basó en la edad cronológica (AU)

This investigations is carried out order to find out the caries prevalence in a population affected by the Down syndrome. The rates obtained to fulfill this objective were CAOD and CAOS for the permanent dentition, and COD and COS for the temporary one. A total of 95 pupils between 6 and 21 years old were examined. 3 groups according to the age were established: the first one between 6 and 8 years old, the one between 9 and 13 years old and the third one between 14 and 21 years old. The following percentages were set for each age group and for boys and girls separately: Carious surfaces in permanent dentition, carious surfaces in temporal dentition, obturated surfaces in permanent dentition, obturated surfaces in temporal dentition and missing surfaces. The results indicate that the caries prevalence in these patients is similar to that obtained in other studies. Nevertheless, the number of obturations found is much smaller.

Pain, facial swelling and trismus evolution after removal of impacted lower third molar were studied in 34 patients obtained from a random sample. A significantly longer length of surgery and facial swelling were observed at 24 hours postoperatively patients with a high anxiety level.

The authors aim to study the relation existing between the chronology of tooth eruption and delayed growth, whether this is delayed growth with or without low genetic height or delayed growth caused by growth hormone deficit. The 50 children included in the sample were studied from the endocrine and dental points of view and it was found that children whose delayed growth is accompanied by a low genetic height or growth hormone deficit presented retardation in dentition and retardation in bone age. However, a retardation in bone age does not necessarily imply a retardation in dentition.

Para los odontólogos dedicados al tratamiento dental infantil, es necesario conocer los posibles riesgos de nuestra terapia, así como los accidentes que pueden ocurrir durante y después de realizada la misma. De esta manera, teniéndolos presentes, así como, conociendo los diferentes tratamientos para solucionar estas emergencias, podremos salvar a nuestro paciente de situaciones que van desde las más leves a aquellas que pueden incluso poner en peligro su vida

This epidemiological study was carried out in order to know the buccal condition of 1,217 children aged between 5 and 15, in Alcalá de Henares, city whose social-economic and geographical characteristics are representative of the national average. The study has been made with data obtained by means of clinical and radiological exploration. The average results which have been found were 5.34 for co rate, 6.53 for the cos, 3.07 for the CAOD y 4.90 for the CAOS. The percentage of children with caries was 88.15%, almost an average of 5.13 caries per child.

The disease which has most prevalence in Spanish school population is dental caries. The children's buccal health decay is as much important as to generate pathology at a local, proximal or general level, alterating his growth and development. Throughout this work, the importance of the problem is reviewed, and the way pediatrician's participation in prevention of this disease, leading to reductions of more than 50% of these lesions, is explained.
