Abstract
Background: Despite some previous promising reports, there has been an increase in prevalence of dental caries. The developing world may be hurt more from the burden of this dental disease. This retrospective study was conducted to evaluate the dental caries prevalence in children during last 5 years in Shiraz. Methods: DMFS (Decayed, Missed and Filled Surfaces) and dmfs (decayed, missed and filled surfaces) indices of 938 healthy 4-12 years old children who had sought medical help at Shiraz Dental School in a 5 year Period from 2010 to 2014 were obtained through their dental records. Results: The prevalence of children with sound permanent teeth (DMFS=0) increased from 66.4 % to 74.9 % from 2010 to 2014 (p=0.001). The highest prevalence for DMFS=0 was reported in 2012 with 84.3 %. The DMFS and dmfs scores had decreasing trends in all age groups except for the 7-9 years old children who experienced an increase since 2013.The girls had statistically significant higher DMFS index than the boys in overall [1.16±1.92 (SD) vs. 0.55±1.33, p<0.001]. No statistically significant difference was seen in dmfs based on gender [13.99±7.18 (SD) vs. 13.29±6.77 for girls and boys. (p=0.06)]. Conclusions: In Shiraz (a big city of Iran) the oral health status had showed some improvement from 2010 to 2014. However, some indices showed points of regression in 2013. Oral indices are more concerning in girls and children of 7-9 years old. The latter may be due to governmental insurance coverage program discontinuance which was considered for permanent first molar restorations in children 6-12 years old.
