Background: Secondary caries is defined as lesions at the margins of existing restorations and is considered as a major reason for their replacement which, if it is left undiagnosed it may lead to loss of vitality of a tooth with many factors contributing to it.
Aims of the Study: The present study aims to determine the prevalence of secondary caries around posterior restorations in patients attending Tishik Dental Hospital University in Erbil city/Iraq.
Methods: A descriptive study was conducted among 61 patients with a total of 113 posterior restorations that are older than one year. Information regarding the presence or absence of secondary caries was noted with the age of the restoration, their types are based upon an extension of the restoration and the restoration material being used either amalgam or composite.
Statistical analysis was done using a t-test for difference and a chi-square test for relations.
Result: Prevalence of secondary caries was found to be (53%) among the understudy patients, restorations in the lower arch showed the highest prevalence, class II restorations had the highest prevalence, Amalgam restorations had a higher occurrence of secondary caries more than composite restoration, which had an age average of less than five years.
Conclusion: Restorations located in the mandible, especially the first molars, showed the highest prevalence of secondary caries, restorations involving the occlusal with the proximal margins had the highest prevalence, their occurrence was highest in restorations being in a period of less than five years.
