Abstract
This epidemiological survey examined 2000 subjects randomly and correlated the data provided with type of restoration, causes of re-restoration and patient factors such as age and gender andoral hygiene measures with restoration longevity. The data was statistically analysed through chi-square and binomial tests. The result obtained was that the amalgam restoration showed the maximum failures (47%) followed by composite (33%) glass ionomer cement (6%) onlay(4%) and inlay(2%). The main cause of replacement of restoration was secondary caries(42%) followed by material fracture(37%) and discoloration(21%). The mean age for the fracture of restoration was 15 years and males are more affected. Co-relating with oral hygiene measures persons brushing once was more prone for replacement of restoration. Conclusion Amalgam was the most widely used restorative material but was associated with more replacement. Secondary caries is most common reason for replacement of restorations.
