A significant trend of declining prevalence of dental caries was observed in urban children ages 5-6 ( p =0.002), along with urban 12 year-olds ( p <0.001).
A significant trend of declining prevalence of dental caries was observed in urban children ages 5-6 ( p =0.002), along with urban 12 year-olds ( p <0.001).
For restoration outcome, both urban and rural of all age groups have an increasing trend of mean ft/FT index.
In 5-6 and 12 years-old rural populations, while the prevalence of caries shows an increasing trend, the mean dmft/DMFT and ft/FT indices show a decreasing trend.
There is an interesting trend to observe in the comparison of rural caries prevalence and dmft/DMFT.
