Aim:
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.
Methods:
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.
Results:
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.
Conclusion:
Intensive preventive measures should be intensified to compensate for oral health inequalities, particularly in MR.
