ABSTRACT
Objetivo: evaluar si los niños y sus padres consideran que la vestimenta del odontopediatra es un aspecto importante en la relación paciente-profesional y cuál sería la de su preferencia. Métodos: se realizó un estudio transversal, analítico en 270 niños/as de 4 y 12 años y uno de sus respectivos padres, en una Clínica Privada y una Institución de Asistencia Colectivizada en Montevideo, Uruguay. El estudio incluyó un cuestionario dirigido a padres/madres y otro a niños/as, y fotografías de odontopediatras con diferente vestimenta: túnica blanca (Imagen 1 y 6), ambo de color lila para la mujer (I-2) y ambo de color verde para el hombre (I-7), equipo con diseños infantiles (I-3, I-8), vestimenta informal ( I-4, I-9) y vestimenta formal (I-5, I-10). Se les solicitó a los niños/as y padres/madres por separado que clasificaran sus preferencias. Resultados: el 29% de los niños/as manifestó preferencia por la imagen 2, seguida por un 25% por la imagen 3. Tanto para las madres como los padres, la imagen más elegida fue la número 3 con 47% y 10% respectivamente. En relación a las opiniones de los padres/madres con respecto a si la vestimenta del odontopediatra influye en el vínculo con su hijo/a, el 83% manifestó que sí, un 16% expresó que no y un 1% opinó da igual. Conclusiones: la vestimenta más elegida por los niños/as encuestados fue el ambo de color lila seguida por la vestimenta con diseño infantil, y la de menos preferencia fue la informal. Para los padres/madres la más elegida fue la vestimenta con diseño infantil. Los padres en general opinaron que la vestimenta influye en el vínculo entre el odontopediatra y su hijo/a; y el comportamiento del niño/a en el consultorio.
Objective: assess whether the children and their parents believe that the dentists attire is an important aspect of patient-professional relationship and, if so, which do they consider to be the most confidence-inspiring attire. Methods: a cross-sectional, analytical study was conducted on 270 children aged 4 -12 years old and one of their respective parents at one private clinic and an institution of assistance collectivized in Montevideo, Uruguay. The study included a questionnaire and photographs of pediatric dentists in different attire: white coat (picture 1 and 6), green scrub for man and violet scrub for women (picture 2 and 7), children's design on the scrubs (picture 3 and 8), casual attire (picture 4 and 9) and formal attire (picture 5 and 10). Children and parents separately asked to rate their preferences. Results: 29% of children expressed a preference for the image 2, followed by 25% by the image 3. For both mothers and fathers, the image was chosen n°3 with 47% and 10% respectively. With regard to the views of parents on whether the dentist dress influences in the bond between the professional and the child , the 83% said it has influence, while 16% said it doesn ́t matter. Only 1% said "do not care". Conclusions: the attire more chosen by children was the violet scrub followed by the scrub with children's design, and the less preference was the casual attire. For fathers and mothers the attire more chosen was the scrub with children's design, Both father and mother felt that clothing affects the bold between the pediatric dentist and his daughter/son; and behavior of the child in the dentist clinic.

Objetivo: Evaluar mediante un estudio longitudinal retrospectivo la efectividad de mantenedores de espacio de arco lingual de banda y ansa en la prevención de la pérdida de espacio posterior a la pérdida prematura de molares primarios.Métodos: Se determinó la pérdida de espacio comparando el espacio disponible en una radiografía bitewing tomada antes de la extracción del molar primario mandibular y una radiografíabitewing posterior a la sucedánea erupción del diente permanente. El grupo control no recibió mantenedor de espacio. Resultados: El grupo de estudio comprendió 82 pacientes; el grupo control fue de 24. La edad media en el momento de extracción fue de 7.9 enel grupo de estudio y de 8.1 en el grupo control pero la edad al momento de extracción no fue una variable estadística significativa. Si lo fue la mayor pérdida de espacio encontrada en niños sin uso de mantenedor. La colocación de un mantenedor de espacio en un tiempo menor a 6 meses después de la extracción, mejoró la posibilidadde erupción de los dientes subsiguientes.Conclusiones: 1. La pérdida temprana del segundo molar primario es más susceptible a la migración dentaria permanente. 2. La colocación de un mantenedor dentro de un plazo de6 meses después de la extracción del primer molar primario, incrementó la erupción dentaria subsiguiente. 3. La pérdida de espacio sólo se explica parcialmente por la no mantencióndel mismo. Son significativos otros factores en la creación de apiñamiento dental. 4. La extracción de un diente primario puede crear pérdida de espacio en niños mayores de 10 años.
Objectives: To evaluate in a longitudinal retrospective study the effectiveness of lingual arch and band and loop space maintainers in preventing space loss after premature loss of mandibularprimary molars. Methods: Loss of space was determined by comparing the available space observed on a bitewingradiograph taken before the extraction ofthe primary mandibular molar, and a bitewing radiograph taken after succedaneum permanent tooth eruption. The control group received no space maintainer. Results: Study group comprised of 82 patients and the control group of 24 patients. Mean age at extraction was 7.9 years in the study group, and 8.1 in the control group, but age at extraction was not a significant variable in the statistics model. Significantly more loss of space wasfound in children without a space maintainer. Fitting a space maintainer less then six months after extraction improved the chance of succeedingteeth to erupt. Conclusions: 1. Early loss of the second primary molar is more susceptible to permanent tooth migration. 2. Fitting an appliance withinless than six months after extracting the first primary molar improved the probability of successor teeth to erupt. 3. Space loss is only partially explained by not maintaining the space. Other factors are significant in creatingcrowded dentition. 4. Extracting a primary tooth may create space loss in children older then 10 years of age.

Introduction: Casein phosphopeptides (CPP) have been shown to be good carriers of calcium, phosphate, and hydroxide ions to promote enamel remineralization with applications in oral care products, professional dental products, and food products. Objectives: Evaluate the cytotoxicity of a casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste in rat fibroblasts. Materials and methods: Cytotoxicity was measured by the Trypan blue dye exclusion assay and the MTT assay. Results: Long term (1, 3, 5, and 7 days) and short term tests (0, 4, 8, and 12 hours) were performed with the Trypan blue dye exclusion assay. Data were analyzed with ANOVA and Kruskall Wallis tests. After one day, the cell viability of the CPP-ACP study group was between 80 and 100%. In the short term experiments, a reduction of cell viability in the study group was observed compared with the control group; yet viable cells were present over the evaluation period. With the MTT assay, a viability of 76.43% was observed in the study group, a significant difference from the control group (P = 0.003). Conclusion: CPP-ACP paste demonstrates low cytotoxicity in rat fibroblast culture.
Introdução: A caseína fosfopeptídea (CPP) tem demonstrado ser uma provedora de cálcio, fosfato e hidróxido, capaz de promover a remineralização do esmalte dentário, sendo utilizada em produtos de higiene oral, materiais dentários e alimentos. Objetivos: Avaliar a citotoxicidade da pasta a base de caseína (CPP-ACP) em fibroblastos de ratos. Materiais e métodos: A citotoxicidade foi avaliada pelos testes de exclusão azul de Tripan e MTT. Resultados: Testes de longo prazo (1, 3, 5 e 7 dias) e de curto prazo (0, 4, 8 e 12 horas) foram realizados com o teste azul de Tripan. Os dados foram analisados com os testes de ANOVA e Kruskall Wallis. Após um dia, a viabilidade celular do grupo de estudo CPP-ACP estava entre 80 e 100%. Nos experimentos de curto prazo, uma redução de viabilidade celular no grupo de estudo foi observada em relação ao grupo controle, mas as células viáveis foram observados durante todo o período de avaliação. Com o método MTT, foi observada no grupo de estudo a viabilidade de 76,43% f, com diferença significativa do grupo controle (P = 0,003). Conclusão: A pasta CPP-ACP demonstra baixa citotoxicidade em cultura de fibroblastos de ratos.

The purpose of this study was to assess differences in the management techniques used by Israeli female and male pediatric dentists. All 112 participants of the meeting of the Israeli Society of Dentistry for Children that was held in February 1999 received a questionnaire which sought information regarding age, sex, behavioral and pharmacological methods used to treat children, having a course in nitrous oxide, general anesthesia, and feelings towards pediatric patients. No differences between female and male dentists were found regarding most management techniques. The majority of dentists used tell-show-do, and gave presents at the end of the appointments. Hypnosis was the least used technique. Papoose board was more prevalent among male dentists than among female dentists. Most dentists reported having the parents present during treatment, and more male dentists used their assistance when restraint was needed. General anesthesia was significantly more prevalent among males than among females (p = 0.01). One-third of the dentists reported feeling aggression toward the pediatric patient. Although not statistically significant, more female dentists reported about feeling aggression than male dentists. Most dentists felt authority towards the pediatric patient. Our findings imply that female and male dentists use similar management techniques when treating children
