Impact of Untreated Dental Caries on Daily Performances of Children From Low Social Class in an Urban African Population: The Importance of Pain

ABSTRACT

Objective: To determine the impact of untreated dental caries on the oral health related quality of life (OHRQoL) of children from low social class in an urban Nigerian population. Material and Methods: The study was conducted among 6 to 15-year-old pupils from low social class in randomly selected primary schools in Ibadan. An interviewer-administered Child Oral Impact on Daily Performances (C-OIDP) questionnaire was used to obtain required information. Oral examination was conducted by calibrated examiners. Data obtained were analyzed with SPSS and test of association done with Mann-Whitney U and Chi-square tests. Results: A total of 1286 pupils participated in the study and 130 (10.1%) had untreated dental caries, out of which 26 (20.0%) had pain from carious tooth. The C-OIDP of children with dental caries was similar to that of children without caries [median 0.0 vs. median 0.0; r = -0.025; p=0.368]. The median COIDP (3.0) of those with untreated dental caries and pain was higher than that of participants with painless caries [0.0; r=-0.768; p<0.001]. There were significant impacts on all eight domains of the OHRQoL of those with untreated dental caries and pain (71.4 ­ 100.0%) when compared to those with painless caries (0.0 ­ 28.6%; p<0.05). Conclusion: Untreated dental caries significantly impacts on OHRQoL of pupils from low social class only when associated with pain.
