Oral manifestations in a group of blind students.

The blind population observed in this study exhibited a relatively low caries rate while the amount of plaque per subject was considered high. Although comparisons within the group were made, no significant differences were revealed when both PHP-M and DMF rates were tested against age and degree of blindness. The percentage of anterior fractures was consistent with recent estimates for the sighted population. Estimates of occlusion also showed close correlation with the general population. Maintenance of oral hygiene remains the most outstanding challenge in the care of blind patients. The problem of motivation as encountered in the sighted patient is magnified here. Disclosing agents for staining plaque are not effective for patient education. Other senses, particularly that of touch, must be utilized when instructing the blind patient in oral hygiene methods.
