The comparison of dental status and oral health related quality of life among children 3–6 years old suffering from congenital heart diseases and healthy children

There are a wide range of oral problems in children which interfere with natural function, sense of health, and child's life quality in general. Congenital heart diseases are also considered as one of the most prevalent developmental defects in children. The aim of this research is to make a comparison between dental status and oral health related quality of life in children 3–6 years old suffering from congenital heart diseases and healthy children. The participants of this case-control study were 44 children suffering from congenital heart diseases and 44 healthy children aged between 3–6 years old. The data of children's oral health related quality of life and dental quality were examined by ECOHIS questionnaire and dmft index, respectively. The obtained data from comparing the two groups in SPSS20 software were analyzed by Mann Whitney test(P<0/05). The average of dmft in control group (6/45) was significantly more than health group (3/77) (p>0/05). The average of oral health related quality of life (OHRQoL) in control group (11/86) was also significantly more than health group (7/41) (p>0.05), and there was not any significant difference between dmft average and OHRQoL average among boys and girls (p> 0/05). According to the current study, the average of dmft and oral health related quality of life (OHRQoL) in 3-6-year-old children suffering from congenital heart disorder is significantly more than healthy children.
