Association Between Oral Health-related Quality Of Life And Atraumatic Restorative Treatment In School Children: An Exploratory Study

Background: The present study′s objectives were to compare the perceptions of oral health-related quality of life (OHRQoL) among school children presents dental caries with that of caries-free school children, and to evaluate the subjective impact of atraumatic restorative treatment (ART) on the OHRQoL of school children. Design: Exploratory study. Setting: Public school in Piracicaba, Brazil. Materials and Methods: The sample was composed of 30 children in the age-group of 8-10 years. The children were divided into two groups: one with caries and other without caries. The information related to OHRQoL was obtained through the administration of the Child Perceptions Questionnaires (CPQ 8-10). To evaluate the impact of ART on the school children′s OHRQoL, the CPQ 8-10 was re-administered 4 weeks after the initial treatment. For statistical analysis we used the nonparametric Wilcoxon test for two dependent variables (test and re-test groups) and the nonparametric Mann-Whitney test for independent variables (test and control groups). Results: It was observed that children with dental caries reported larger impact of oral health conditions on the quality of life when compared with the caries-free group, especially in the emotional and social well-being domains (P≤.05). After the school children who presented with dental caries received ART, there was improvement in the median scores of CPQ 8-10 in all of the domains, but particularly in the functional limitation domain (P≤.05). Conclusion: Dental caries exerts a strong influence on the OHRQoL of children. ART was shown to be a simple and painless caries management approach that could improve the OHRQoL of school children.236738741Jokovic, A., Locker, D., Tompson, B., Guyatt, G., Questionnaire for measuring oral health-related quality of life in eight-to ten-year-old children (2004) Pediatr Dent, 26, pp. 512-518Barbosa, T.S., Tureli, M.C., Gavião, M.B., Validity and reliability of the Child Perceptions Questionnaires (2009) BMC Oral Health, 9, p. 13Biazevic, M.G., Rissotto, R.R., Michelcrosato, E., Mendes, L.A., Mendes, M.O., Relationship between oral health and its impact on quality of life among adolescents (2008) Braz Oral Res, 22, pp. 36-42Frencken, J.E., Pilot, T., Songpaisan, Y., Phantumvanit, P., Atraumatic restorative treatment (ART): Rationale, technique and development (1996) J Public Health Dent, 56, pp. 135-140Frencken, J.E., The ART approach using glass ionomers in relation to global oral health care (2010) Dent Mater, 26, pp. 1-6Taifour, D., Francken, J.E., Beiruti, N., Van'T Hof, M.A., Truin, G.J., Effectiveness of glass ionomer (ART) and amalgam restorations in the deciduous dentition: Results after 3 years (2002) Caries Res, 36, pp. 437-444Frencken, J.E., Makoni, F., Sithole, W.D., ART restorations and glass ionomer sealants in Zimbabwe: Survival after 3 years (1998) Community Dent Oral Epidemiol, 26, pp. 372-381Holmgren, C.J., Lo, E.C., Hu, D.Y., Wan, H.C., ART restorations and sealants placed in Chinese schoolchildren-results after three years (2000) Community Dent Oral Epidemiol, 28, pp. 314-320Wang, L., Lopes, L.G., Bresciani, E., Lauris, J.R., Mondelli, R.F., Navarro, M.F., Evaluation of Class i ART restorations in Brazilian schoolchildren: Three-year results (2004) Spec Care Dentist, 24, pp. 28-33Van Gemertschriks, M.C., Van Amerongen, W.E., Ten Cate, J.M., Aartman, I.H., Three-year survival of single-and two-surface ART restorations in a high-caries child population (2007) Clin Oral Investig., 11, pp. 337-343Pendrys, D.G., Use of the ART Technique Within the School Setting Can be A Practical and Effective Method of Treating Caries among Large Populations of Underserved Children (2010) J Evid Based Dent Pract, 10, pp. 13-15Schriks, M.C., Van Amerongen, W.E., Atraumatic perspective of ART: Psychological and physiological aspects of treatment with and without rotary instruments (2003) Community Dent Oral Epidemiol, 31, pp. 15-20(1997) Oral Health Surveys, Basics Methods, , Word Health Organization Geneva: Word Health OrganizationAyres, M., Ayres Jr., M., Ayres, D.L., Santos, A.S., (2007) BioEstat 5. 0.
