Purpose: Stroke is a leading cause of death in developed countries. Recently, its connection with oral health has
been a focus of the medical literature. The aim of this study was therefore to statistically examine the oral health
of subjects who previously suffered from stroke and provide a guide for the dental treatment of these patients.
Materials and Methods: Stroke patients at least one year after the stroke episode and age- and sex-matched
healthy controls were examined: dental and medical stroke histories were recorded, followed by a detailed orofacial
examination. A categorisation into three ‘dental’ subgroups of stroke patients was carried out based on their residual
symptoms, the functional deficiency of limbs, and chewing and swallowing difficulties. Indices quantifying oral
hygiene (OHI-S), dental status explained by the number of decayed, missing, and filled teeth (DMFT), periodontal
status (CAL, CPITN, Mühlemann index), and the status of prosthetic treatment (prosthetic index) were assessed.
Statistical comparison was performed between the patient and age- and sex-matched control subjects, as well as
between subgroups of stroke patients.
Results: One hundred two stroke patients and 98 healthy age- and sex-matched control subjects were examined.
The oral health and dental status of stroke patients was worse compared with the control group. Stroke patients
had significantly more decayed (2.3 ± 3 vs1.1 ± 1.8; p = 0.01) and missing (19.3 ± 9.5 vs 15.5 ± 9.3; p = 0.005)
teeth, but significantly fewer filled (3.6 ± 4.7 vs 7.7 ± 5.6; p < 0.001) teeth than did the healthy controls. In stroke
patients, clinical attachment loss (CAL) was double that of the control group (p < 0.001). A comparison between
the subgroups of stroke patients revealed that the most severe findings were in patients who had chewing and
Discussion: According to these results, the combination of risk factors of stroke, residual neurological signs after
stroke, and poorer socioeconomic conditions results in poor oral hygiene, poor dental and periodontal conditions,
and a lower prosthetic index. Special care and attention should be given to the oral hygiene and dental treatment
of such patients, to enable good nourishment.
