This study was conducted to assess the level of dental flourosis and Decaying, Missing, Filled Tooth (DMFT) of selected patients, in district Mardan village Rustam and District Mianwali village Harnoli. Study was conducted among people of age 10 - 60 years. The regions of Rustam and Harnoli are known to have high value of fluoride in drinking water. A cross sectional study was conducted among the subjects and the grade of fluorosis was calculated according to Deans Fluorosis Index. DMFT of each subject was also calculated. Total of 100 subjects were selected by simple random sampling technique among the population of Rustam and Harnoli and they were observed for the extent of fluorosis they had along with the number of decayed, missing and filled teeth they had Most of the population uses underground water, the water people commonly used was collected and was tested for amount of fluoride. The results show that there is a strong relationship between fluoride level and extent of fluorosis. Populations of both areas have dental fluorosis due to high concentration of fluoride in drinking water and also comparatively low DMFT because fluoride has caries protective effect

Conventional and surgical endodontic therapy is accepted as foreseen clinical procedures that save teeth with pulpal disease which would otherwise be extracted. When a tooth's pulp is irreversibly damaged or infected due to caries, cracks, trauma, or leaky restorations, endodontic therapy or extraction are the only workable options [1]. Teeth undergoing initial endodontic therapy have a very high survival rate. Some teeth that continue to show signs of pathosis after the initial therapy will require nonsurgical (orthograde) retreatment [2]. Intentional replantation is valid and inevitable for cases in which nonsurgical endodontic retreatment is unsuccessful or is impractical and endodontic surgery is hindered because of anatomic restrictions [3].
