Periodontal Health Status of A Group of (Non-Institutionalized) Mentally Disabled Children in Khartoum State
ABSTRACT Aim The aim of this study is to assess the periodontal health status and its determinants among a group of mentally disabled children in Khartoum State and to compare it with a control group of children of normal intelligence. Methods Thirty seven mentally disabled children aged 8-10 years were examined at five centres of mentally disabled children in Khartoum State. A control group with normal intelligence quotient of a similar age and socioeconomic status was selected from schools nearby the centres visited. Both mentally disabled children and the children in the control group were examined for their plaque index, gingival index and periodontal pocket depth. A comparison was made between the mentally disabled children and the healthy children as well as between the subgroups of the mentally disabled children (mild, moderate, and severe). Questionnaires concerning the degree of mental disability, level of parent education, role of parents toward child oral health, were also used. Results The results revealed that the mentally disabled children showed higher scores of plaque and gingival index (1.9, 1.7 respectively) when compared with the plaque and gingival index of the control group (0.6, 0.6 respectively). No increase in gingival sulcus depth in both study and control group was found. According to the degree of mental disability there was statistically significant difference in plaque and gingival index among the mild, moderate and severe subgroups (P=0.001), the plaque and gingival index tend to increase with the severity of mental retardation. Conclusion. Mentally disabled children showed more plaque when compared with healthy controls. Periodontal disease was more prevalent among mentally disabled children as presented in the form of gingivitis and the degree of severity depends on the degree of mental disability.
