Comparison of the Success and Longevity of Glass Ionomer Cement In Relation To Amalgam Restorations in Primary Molars – A Retrospective Study.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 3
Abstract
Background: Dental caries has been a highly prevalent disease in the world, representing the most common infectious disease in the paediatric population and restoration become a major treatment delivered in them. Today, the pediatric dental practitioner has multiple choices with many materials from which to select for each restorative situation. However pediatric practice of restoring class II is challenging due to the time tested failure of amalgam at isthmus region– explained due to improper depth high restoration sharp axiopulpal line angle and overcoming, most important is the lack of bulk due to primary tooth anatomy which made clinicians stick to the newer tooth coloured restorative materials but the limitations of lack of strength, excessive salivation also hampers the success of these material. Fractured or failed restoration could lead to early involvement of pulp and loss of teeth which can cause a lot of problem. So our study was done to assess the best restorative material as far as success and longevity is concerned. Aim: This study aims to compare the success longevity of glass ionomer cement and amalgam restoration in class II on primary molars. Settings and Design: The study is a retrospective hospital based study Material and Methods: One hundred twenty children aged 5-9 years who had obtained treatment from department of pedodontics and preventive dentistry, KVG Dental College and hospital were selected for the study. Children having either glass ionomer cement or amalgam restoration done by postgraduates were recalled for the study and the children were divided into two groups based on the type of restoration. GROUP 1- Glass ionomer cement restoration GROUP 2- Amalgam restoration. After that comparison is done using evaluation criteria. Statistical Analysis: The data will be statistically analyzed using Mann Whitney test. Results: The results showed a success percentage of 44.2% for glass ionomer cement and 73.1% for amalgam in fracture resistance, a success percentage of 67.3% for glass ionomer cement and 94.2% for amalgam in anatomic form, a success percentage of 80.8% for glass ionomer cement and 76.9% for amalgam in marginal intergrity and a success percentage of 86.5% for glass ionomer cement and 78.9% for amalgam in case of secondary caries. Conclusion: Fracture rate is high in glass ionomer cement compared to amalgam. This is mainly due to poor strength. With proper modification in cavity, proper isolation amalgam has high success longevity rate in primary tooth than glass ionomer cement .Amalgam is a better material for Class-II cavities of primary molars having limited life span in the mouth.
