Résumé
Young chronically ill children receive a greater sugar load from liquid medications than do healthy children. They receive variety of oral liquid medications that healthy children do not This study was planned to know the levels of oral hygiene and Dental caries in children on long term liquid oral medicines (LOM) and to know out if any difference existed between these and children not on LOM. 51 children on LOM were compared to 54 not on LOM after equalising for age, oral hygiene and diet intake. Highly significant difference was found for dmft and dmfs in 2-6 year age group and dmft+ DMFT for 6-13 years age group, mostly posterior teeth were affected and for this the difference was statistically significant in 2-6 year old children. Percentage of children with dmft>5 significantly increased in 2-6 years old children on LOM, when compared to that of control. Percentage of various grades of lesions (relating to the severity) also increased with an increase in the duration of LOM.
