RESUMEN

OBJECTIVES: The objective was to analyze the impact of preventive programmes on oral quality of life in school students aged 11-12 yrs. STUDY DESIGN: In the school year 1996/97, a quasi-experimental study was initiated in Granada province with four groups of students aged 6-7 yrs: Sealant + Fluoride (sealants on first permanent molars applied in the health centre for a 3-yr active programme, and fluoride varnish applied every four months for 3 yrs, n=65), Sealant (only sealants, n=80), Fluoride (only fluoride varnish, n=107) and Control group (n=59). All students were examined every 6 months at school during the 3-yr active programme and received an oral health report after each examination. At 5.5 yrs (school year 2002/03), after 2.5 yrs with no programme, students were again examined and completed a questionnaire on oral quality of life scored from -6 (minimum) to +6 (maximum). RESULTS: Oral quality of life values (+/- standard deviation) were: 3.31+/-0.30 (Sealant + Fluoride), 3.11+/-0.27 (Sealant), 3.18+/-0.23 (Fluoride) and 2.95+/-0.32 (Control), with no statistically significant differences among them. CONCLUSIONS: Fissure sealant and fluoride varnish programmes had no significant influence on oral quality of life after a 5.5- yr follow-up (3 yrs of active programme plus 2.5 yrs of discontinuation).

RESUMEN

Objetivos: El objetivo es analizar el impacto de programas preventivos sobre la calidad de vida oral en escolares de 11- 12 años. Diseño del estudio: En el curso académico 1996/97 se inició un estudio quasiexperimental en la provincia de Granada con cuatro grupos de escolares de 6-7 años de edad: Sellador + Flúor (selladores en primeros molares permanentes aplicados en el centro de salud, durante 3 años de programa activo, y barniz de flúor aplicado cuatrimestralmente durante 3 años, n=65), Sellador (sólo selladores, n=80), Flúor (sólo barniz de flúor, n=107) y grupo Control (n=59). Todos los escolares fueron explorados cada 6 meses en los colegios durante los 3 años de programa activo, entregándoseles un informe de salud oral tras cada exploración. Tras un periodo de discontinuidad de 2.5 años, en el curso escolar 2002/03 (a los 5.5 años), los escolares fueron explorados, y se les pasó un cuestionario de calidad de vida oral, cuya puntuación va de -6 (mínima) a +6 (máxima). Resultados: Los valores de calidad de vida oral (± desviación estándar) fueron: 3.31±0.30 (Sellador + Flúor), 3.11±0.27 (Sellador), 3.18±0.23 (Flúor) y 2.95±0.32 (Control), sin diferencias estadísticamente significativas entre ellos. Conclusiones: Los programas de Sellador de fisuras y Barniz de flúor no muestran influencia significativa sobre la calidad de vida oral a 5.5 años de seguimiento (3 años de programa activo y 2.5 años de discontinuidad)

RESUMEN

OBJECTIVE: To analyse the effect of a public school odontological programme of fissure sealants on the private demand for restorative dentistry for temporary teeth. DESIGN: A longitudinal, comparative study was conducted. It had 2 groups, control and sealant, with 3 years monitoring. SETTING: Santa Fe Health Area, concretely in the local districts (LD) of Santa Fe and Pinos Puente, Granada, Spain, starting in the school year 1996/1997. PARTICIPANTS: The sealant group was selected from the Santa Fe LD (which had a public programme of fissure sealants) (n=129); and the control group (n=120), from Pinos Puente LD. INTERVENTIONS: All the school students were examined (+ report issued) in the schools every 6 months for 3 years. The sealant group children received at the health centre fissure sealants in their first permanent molars. MAIN MEASUREMENTS: The restorations performed in temporary teeth for both groups were analysed (x+/-EE) during the study at 12, 24, and 36 month follow-up. RESULTS. The sealant group had a significantly greater increase in restorative treatment for temporary teeth (P< .05) than the Control group at all monitoring points. CONCLUSIONS: A public programme of fissure sealants raised private restorative treatment for temporary teeth.

RESUMEN

Objetivo. Analizar la influencia de un programa escolar odontológico público de selladores de fisuras sobre la demanda privada de odontología restauradora en dentición temporal. Diseño. Se realiza un estudio longitudinal, comparativo, con 2 grupos de estudio: grupo sellador y grupo control, a 3 años de seguimiento. Emplazamiento. El estudio se lleva a cabo en el Distrito Sanitario Santa Fe, de Granada, concretamente en las zonas básicas (ZB) Santa Fe y Pinos Puente, y comienza en el curso escolar 1996-1997. Participantes. El grupo sellador se seleccionó de la ZB Santa Fe (con programa público de selladores de fisuras) (n = 129) y el grupo control (n = 120), de la ZB Pinos Puente. Intervenciones. Todos los escolares fueron explorados (con emisión de un informe) semestralmente en los colegios durante 3 años. Los escolares del grupo sellador recibieron selladores de fisuras en los primeros molares permanentes, aplicados en el centro de salud. Mediciones principales. Se analizan las restauraciones realizadas (media ± error estándar) durante el estudio a 12, 24 y 36 meses de seguimiento, en la dentición temporal, para los 2 grupos de estudio. Resultados. El grupo sellador presenta un incremento significativo de tratamiento restaurador en la dentición temporal (p < 0,05) frente al grupo control en cualquier período de seguimiento. Conclusiones. Un programa público de selladores de fisuras produce un incremento de tratamiento restaurador privado en dentición temporal

RESUMEN

lntroducción:(fundamento y objetivo): El objetivo es analizar la influencia de algunos programas públicos odontológicos sobre la demanda de odontología restauradora privada. Métodos: En el curso 96/97 se inició un ensayo de campo en Granada, con cuatro grupos ce escolares de 6-7 anos de edad Sellador (aplicados en el Centro de Salud, n=121), Sellador+Flúor (+ barniz de flúor en los colegios, n=119), Flúor (n=137) y Con-trol (n-95). Todos fueron explorados al inicio, y a los 6 meses. Se analiza el incremento de odontología restauradora privada, a través del índice cie restauración (dientes obturados del total de dientes cariados + obturados). Resultados y conclusiones El índice de restauración aumentó significativamente en los cuatro grupos. El incremento medio (- desviación estándar) de obturaciones 2s mayor en los grupos Sellador (0.54-1 1 57) y Sellador+Flúor (0.55+-1.27), que en los grupos Flúor (0.23 0.99) y Control (0.19ñ0 80), no habiendo diferencias significativas de incremento entre los grupos Sellador +Flúor y Sellador, ni entre Flúor y Control. Se concluye que un programa de selladores desde un centro de salud produce un incremento de la demanda de odontología restauradora, pero no un programa de flúor tópico profesional (barniz) realizado en el colegio (AU)
