Evaluation of Dental Caries Prevalence among Children in Mosul City Center Using Significant Caries Index

Abstract

Aims of the study: To evaluate the prevalence of dental caries among children aged 9-10 years in Mosul City Center and to compare between traditional index and significant caries index of these students. Materials and Methods: The study sample was obtained from third and fourth class students from eight randomly selected primary schools in Mosul City Center. Sample size was 363 students, 225 females and 138 males. Students' ages were 9 and 10 years. All primary and permanent teeth were examined for the presence of decay, missing or filling teeth/surfaces. Mean DMFT, DMFS, dmft and dmfs were calculated for the students together and separately for each sex. The mean Significant Caries Index (SiC) was also calculated as the mean DMFT and DMFS of the one third of the students with the highest caries scores. Results: The SiC index was significantly higher in all comparisons with traditional DMF index (p < 0.000). A comparison between the two indices indicated that there is a large children subgroup presented with a high caries rate. Conclusions: The mean DMF values did not accurately reflect the skewed distribution of dental caries leading to incorrect conclusions that the caries rate of the statewide population is under control. It is better to use SiC index instead of the traditional index.

Comparison Of Dental Caries Experience Among 35-40 Year Old Population Using Dmft And Dmfs Index - An Institution Based Cross Sectional Study

“…Even though it has failed to meet the challenges of the 21st century, it is still being used as a well-established key for measuring caries experience in dental epidemiology (Dye et al, 2007). The DMFT/DMFS index can be applied to both primary and permanent dentition and is expressed as the total number of teeth (DMFT) or surfaces (DMFS) that are decayed (D), missing (M), or filled (F) in an individual (Gasgoos, Al-Sayagh and Jazrawi, 2012…”

The study of caries incidence in children according to WHO Significant Index of Caries

“…ВОЗ официально приняла данную методику и внедрила ее в разные центры, которые сотрудничают с ВОЗ. Подобные исследования проведены во многих странах [6,10,14,[16][17][18]20]. К сожалению, в стоматологической науке в Украине этот индекс пока не получил широкого распространения.…”
