Objective: To determine the relationship between the ceo-d index and the oral health-related quality of life (OHRQoL) in preschool children of the I.E. César Vallejo, Chorrillos - 2018. Materials and methods: An observational and cross-sectional study, which evaluated 118 children aged 3 to 5 who registered dental caries according to the ceo-d index and the ECOHIS survey for the perception of oral health-related quality of life. The statistical tests used in the research were the Student´s t test, Kruskal-Wallis H test and Mann-Whitney U test, with a significance level of 0.05 and a Spearman coefficient of 0,01. Results: The average of the ceo-d index was 6,60 ± 3,95, which indicates a very high level of severity, and a frequency of 88.98 %. The ECOHIS survey showed a negative impact (21,72 ± 14,15) and a high frequency (85.59 %) on the oral health- related quality of life. The most frequent dimension was "functional limitation" (83.90 %). According to the Spearman coefficient, there is a significant moderate positive direct relationship (r = 0,682) between the variables "dental caries" and "quality of life". This relationship prevails in the female (21.83 ± 12.56) and 5-year-old (33.67 ± 11.17) groups,, both of which were statistically significant (p = 0.000). Conclusions: Dental caries generate a negative impact on the quality of life that affects the various activities of children, and has repercussions on their family and environment. The larger the number of dental caries and severity, the greater negative impact on the quality of life. This condition worsens with increasing age, and girls are more prone to have it.Objetivo: Determinar la relación entre el índice ceo-d y la calidad de vida en la salud oral (CVRSO) de preescolares de la I.E. Cesar Vallejo de Chorrillos – 2018.
Materiales y métodos: Estudio observacional y transversal que evaluó a 118 niños de 3 a 5 años. Se registró la experiencia de caries dental con el índice ceo-d y la encuesta ECOHIS para la percepción de la calidad de vida en salud oral. Las pruebas estadísticas empleadas fueron t de Student, Kruskal-Wallis y U Mann-Whitney, con nivel de significancia 0,05; y coeficiente Spearman 0,01.
Resultados: El promedio del índice ceo-d (6,60 ± 3,95) indica un nivel de severidad muy alto y frecuencia 88,98 %. El ECOHIS reflejó un impacto negativo en la calidad de vida en salud oral (21,72 ± 14,15), y una alta frecuencia (85,59 %); la dimensión más frecuente fue limitación funcional 83,90 %. Según el coeficiente de Spearman, existe una relación directa positiva moderada significativa (r=0,682) entre las variables caries dental y calidad de vida; y demuestra en esta relación que su predominio radica en el sexo femenino con 21,83 ± 12,56, y el grupo de 5 años que obtuvo 33,67 ± 11,17, ambos estadísticamente significativos (p=0,000)
