The present study revealed that the overall oral hygiene
status of the study population was poor with prevalence
rates of 14.9%, 63.4%, and 21.8% for good, fair, and
poor components, respectively, [Figure 2] which are
similar to the values reported in a previous study
conducted on mentally disabled children attending
special schools in Udaipur, India.[22] The reasons for
this may include the reduced manual dexterity of the
participants, joint laxity, and lack of comprehension
of oral hygiene needs due to mental difficulties. They,
therefore, need help to carry out routine oral hygiene
measures.
