Abstract
This longitudinal survey aims to demonstrate improvement in oral hygiene among a group of youth with visual impairment (VI) achieved by repeated oral hygiene training, compare their progress with healthy peers (CG) and assess their oral health knowledge. In 100 VI (55♀, 45♂; ± 17.8 years) and 45 CG (23♀, 22♂; ± 17.2 years) oral hygiene training and a Quigley-Hein Plaque Index (QHI) rating were repeated six times at three-month intervals. The VI were divided into four subgroups according to the toothbrush hardness/type. A questionnaire was given to both groups. Appropriate statistical analyses were performed at 5% significance level. Both groups showed reduction in QHI, the VI had overall higher QHI values than CG. Use of an electric toothbrush in VI led to lower QHI in the last examination (p < 0.03). 69% of participants recommended dental specialists to improve communications by acquiring more illustrative aids. VI changed toothbrush less often (p < 0.02). A higher incidence of dental plaque was confirmed in VI compared to CG. After education and individual training, gradual plaque reduction has occurred in both groups. Using an electric toothbrush in VI resulted in better QHI outcomes. Repetitive preventive intervention in youth with VI helped them to adopt healthier oral hygiene habits.
