Basic statistical analyses of the data. including the cross-tabulation were carried out, and where appropriate, the chi-square test was used to compare the frequency differences. Data were collected for 84 restorations placed in permanent teeth. Amalgam [60.7%] was the most commonly used restorative material followed by Glass lonomer Cement [G.I.C] [27.4%] and temporary restorations [8.3%] with a minimal use [3.6%] of resin composite, p<0.01. Most of the restorations [88.1%] were initial placements, while [11.9%] were replacement restorations, p<0.01. Primary caries [79.7%] was the major reason for the initial placements and secondary caries [80%] for the replacement of restorations. Amalgam and G.I.C were the most commonly used restorative materials, and primary caries was the major reason for the initial restorations, and secondary caries for replacement restorations
