Abstract

 

Adequate knowledge of reasons for the failure and replacement of restorations will lead to how to avoid the pitfalls on replacing restoration for longer survival. To find out the reasons adduced for the failure of restoration and the pattern of those failures in conjunction with gender effect on the result. A retrospective cross-sectional longitudinal study of regular attendees using available records of patients. The records are categorized into regular or non-regular attendees using a baseline definition for all records. The regular attendees are then recalled to find out the actual state of restorations in the mouth compared to the records in the file. The data collected showed that more restorations are placed on females (79.4%) than males (20.6%). The reasons adduced for replacement are fractured restoration 56.2%, marginal defect/Ditching (19.5%), recurrent caries (15.4%), dislodged restoration (8.9%). This pattern is almost repeated when considering the gender distribution of reasons for replacement of amalgam restoration. In this study, fractured restoration was the major reason for amalgam restoration replacement which may be due to patient’s factor of cultural tradition or operator’s factor which may hinge on lack of or full understanding of the basic principle of cavity preparation. The marginal defect could be due to the presence of r-2 phase in the amalgam while recurrent caries was not a danger to amalgam failure in this environment as in America and Europe. Dislodged restoration may be due to lack of adequate preparation for the retention of the restoration. The major reasons for amalgam replacement in this study is fractured restoration with recurrent caries coming third on the list of causes for replacement.

Key words: Amalgam, gender distribution, single surface restoration, replacements.
