Oral health status of students with and without disabilities in Erfurt, Germany

Abstract

The aim of this study was to make a comparison of the oral health status of students with and without disabilities (Sw/D, Sw/oD) aged 6-18 years from the city of Erfurt. 328 students with mental retardation (MR), physical disability (PD) and hearing impairment (HI) were examined according to WHO standard (1997). The control group consisted of 400 age-matched Sw/oD. Data analysis was performed in age groups 6-12 and 13-18 years. Caries prevalence of 6- to 12-year-old Sw/D (68.7%) was significantly higher than in Sw/oD (57%) (p=0.019).The caries experience of Sw/D was 2.3 dmft/0.5 DMFT and 1.6 dmft/0.4 DMFT of Sw/oD. PD had a lower restorative index than other Sw/D (p ≥ 0.023). There was no difference in caries prevalence and caries experience among 13- to 18-year-old Sw/D (51%; 1.9 DMFT) and Sw/oD (59%; 2.1 DMFT). MR had a lower prevalence of fissure sealants and less sealed teeth (p ≤ 0.042) and their periodontal health was inferior compared to other Sw/D. Intensive preventive measures should be intensified to compensate for oral health inequalities, particularly in MR.
