Impact of Caries Experience on the Oral Health-Related Quality of Life of Pre-school Children and their Families in an Indian City - An Evaluative Study.

Background: The presence of dental caries may have a negative impact on well-being of children and their parents, causing pain and discomfort, leading to poor oral health-related quality of life (OHRQoL) in them. The objective of this study was to evaluate the impact of different levels of caries experience on the OHRQoL of pre-school children and their families in Odisha, assessed using Odia version of Early Childhood Oral Health Impact Scale (Od-ECOHIS).

Methodology: A cross-sectional survey was carried out on a sample of 369 pre-school children using Od-ECOHIS. Dental caries was recorded using International Caries Detection and Assessment System (ICDAS) index.

Result: The total score of ECOHIS ranged from 0 to 42 with a mean of 2.4 (±5.3) and a median score of 0. The items bearing high mean scores in the child impact section were related to "pain", "difficulty in drinking hot or cold beverages", "difficulty in eating some food", and "irritable or frustrated". Though half of children (50.4%) had cavitated carious lesions, the prevalence of negative impact was 30.6%. Compared to the child being caries-free, the expected count of total Od-ECOHIS score increased by 1.54 times if the child had white spot lesion and 1.94 times if the child had a cavitated lesion.

Conclusion: Presence of dental carious lesions has a significant impact on OHRQoL of pre-school children and their families measured by using Od-ECOHIS even after adjusting for SES and caregivers' perception of their children's oral health.
