Evaluación del estado de salud bucodental en preescolares: estudio epidemiológico longitudinal (1993-1994), Córdoba, Argentina

A one-year longitudinal survey was carried out on a sample of the Cordoba City 4-year old kindergarten population (n = 820); so as to determine the role of several variables upon the incidence of caries. The dmf-t, dmf-s, oral hygiene and oral health indexes as well as incidence rates and caries relative risks of caries were inversely related to the socioeconomic level (SEL) of the children involved. Thus in the SEL III (typical proletariat, non-typical proletariat and sub-proletariat) children, the relative risk of caries was almost five times higher (RR = 4.9) than in the SEL I (entrepreneureal and managerial bourgeoisie) children. In SEL I, almost all new lesions occurred on smooth surfaces (61.2%), while in SEL III the molar occlusal faces were mainly affected (66.3%). Daily sugar intake was higher in SEL III children but experience of caries showed poor correlation to the amount (r = 0.40) and frequency (r = 0.52) of carbohydrate intake. No significant interlevel differences were observed in the biochemical salivary parameters analyzed. Assisted toothbrushing and fluoride topications strongly lowered the incidence of caries among SEL III children, also making the corresponding rates fall almost to SEL I values (0.31, 0.23 and 0.22 vs. 0.21). In conclusion, SEL III children should be treated prophylactically with effective preventive measures, because of their susceptibility to caries. Such preventive measures include assisted toothbrushing and fluoride topications.Se realizo un estudio longitudinal de un ano de duracion en una muestra (n = 820) de la poblacion preescolar de 4 anos de la Ciudad de Cordoba, Argentina, para establecer la participacion de diversas variables en la incidencia de caries. Los indices ceo-d, ceo-s, de higiene oral y de salud bucodental, como tambien las tasas de incidencia y los riesgos relativos de caries estuvieron inversamente relacionados con el Nivel Economicosocial (NES) de los ninos. En los preescolares del NES III (proletariado tipico, proletariado no tipico y subproletariado), el riesgo relativo de experimentar caries fue casi cinco veces mayor (RR = 4,9) que en el NES I (burguesias empresarial y gerencial). En el NES I, la mayoria de las nuevas lesiones se localizaron en las superficies lisas (61,2%), mientras que en el NES III afectaron predominantemente las superficies oclusales de los molares (66,3%). El consumo diario de azucares fue mayor en los ninos del NES III, pero la experiencia de caries se correlaciono debilmente con la cantidad o frecuencia de ingesta de estos carbohidratos (r = 0,40 y 0,52, respectivamente). No se registraron diferencias significativas interniveles en los parametros bioquimicos salivales analizados. El cepillado dental asistido y las aplicaciones topicas fluoruradas disminuyeron fuertemente la incidencia de caries en los ninos del NES III, reduciendo las correspondientes tasas a valores muy proximos a los del NES I (0,31, 0,23 y 0,22 vs. 0,21). Se concluye que los ninos del NES III, por su susceptibilidad a la caries, deberian ser asistidos precozmente con medidas preventivas eficaces, como lo son el cepillado dental asistido y las aplicaciones topicas fluoruradas.

Estudio Radiográfico de la Asociación de Antioxidantes y Bifosfonatos en Remodelación Ósea Peri-Implantaria

Previous studies have shown that bisphosphonates are potent inhibitors of bone resorption. Olive oil (O) is rich in monounsaturated fatty acids with potent anti-oxidant properties. The objective of this work was to study the effect of alendronate treatment (AL) and pamidronate (PA) and O on tissue regeneration. Formulas 0.5 mg / kg for AL dosed, and 0.6 mg / kg for PA. O was administered in the diet, 50 g / kg. Fifty-four male rats Wistar were divided into 6 groups. The control group (C) received weekly 0.3 ml / 100g body weight of saline subcutaneously. The group (AL) received a weekly dose subcutaneously in the left posterior limb. The group (PA) was placed as the previous group. The group (O) was treated in food and in the areas of surgery received subcutaneousinjection with saline. The group (ALO) received combined treatment with Al and O. The group (PAO) was treated the same as before. Surgery consisted of a longitudinal incision in the warm using a circular on the flat side of each tibia until the medullary bone defect. X-rays at 0, 7, 15, 30, 60 and 90 days were taken and analyzed with Image Pro Plus Software. Statistical studies were conducted through analysis of variance to two and three classification criteria. Results: an increase in the average bone mineral density (BMD) was evident as time progresses in all groups, with PA still evident at 60 days. Or treatment showed efficacy in bone remodeling observed a peak at 60 days. Conclusions: This suggests that O represents a therapeutic option for the treatment of bone disease.
