RESUMO
Se realizó un estudio descriptivo transversal en 150 pacientes con edades comprendidas entre 6 y 9 años del servicio escolar Ángel Hernández Chirino del municipio Guanabacoa, en el curso escolar 2000-2001, con el objetivo de identificar las principales afectaciones de los segundos molares temporales y las acciones preventivas que se pueden llevar a cabo por el estomatólogo general integral (EGI). Se observó que el 40 por ciento de los casos tenía obturaciones realizadas, el 29,3 por ciento ya tenía realizadas extracciones, el 25,3 por ciento presentaba caries extensas, el 3,4 por ciento de oligodoncia y el 2,0 por ciento pérdidas por trauma. Resultó significativo que ya el 53,6 por ciento había sido atendido en atención secundaria por pérdida de espacio y al 46,4 por ciento se le aplicó un mantenedor de espacio por el EGI en atención primaria, predominando los realizados con la técnica de acrílico. Se concluye que el tratamiento realizado por el EGI en la atención primaria es fundamental, pues ante la pérdida de dientes temporales, debe aplicarse la técnica de mantenedores de espacio para evitar que ese paciente pase a la atención secundaria(AU)
A descriptive cross-sectional study was conducted in 150 patients aged 6-9 from "Angel Hernández Chirino" school service in the municipality of Guanabacoa, during the school course 2000-2001, aimed at identifying the main affectations of the second temporal molars and the peventive actions the general comprehensive stomatologist may take. It was observed that 40 percent of the patients of the cases had fillings, 29.3 percent had extractions, 25.3 percent presented extensive caries, 3.4 percent had oligodontia, and 2 percent losses due to trauma. It was significant that 53.5 percent had already received secondary attention due to loss of space. 46.4 percent were applied a space-maintainer by the general comprehensive stomatologist at the primary health care level. It was observed a predominance of those made by the acrylic technique. It was concluded that the treatment applied by the general comprehensive stomatologist at this level is fundamental, since this technique should be used when loss of temporal tooth occurs in order to avoid that this patient seeks care at the secondary level(AU)

⢠Here, we investigated the spatial and temporal abundance of mycelial mats in a tropical rain forest to determine their effects on the concentration of mineral nutrients in soils and fine roots. ⢠Mats were marked and followed over three seasons. Fine-root mass and the concentration of mineral nutrients in both soils and roots were determined for mat-associated soils and for a control group. ⢠Mats were more abundant in the dry season than in the wet season. The concentration of mineral nutrients in soils and fine roots increased from the rainy season to the end of the dry season. Mats appeared to affect the concentration of phosphorus, potassium and calcium, and the carbon : nitrogen and nitrogen : phosphorus ratios in soils and roots during all seasons. ⢠Mats appeared to compete with plants for certain minerals. This could be part of 'bottom up' effects that may influence underground herbivory, as well as the above-ground concentrations of mineral nutrients in plants. Mats are relevant to understanding soil biodiversity and the potential feedback paths between the soil and above-ground subsystems.
