Knowledge Awareness and Practice on Assessment of Marginal Fit in Fixed Partial Dentures among Undergraduates

The importance of Marginal adaptation of fixed prosthodontics is to assess the smallest number of gap measurement on margins of single Crowns to get relevant results for gap analysis. Factors affecting marginal adaptation of fixed prosthodontics include the type of finish line, the material used for impression, the luting cement and other factors include the method of fabrication. The aim is to assess the knowledge and attitude towards the marginal fit in fixed partial denture among the undergraduate and its application in their day-to-day practice. A cross sectional study was conducted online with a pre-structured questionnaire containing 10 questions among the 100 undergraduates. Persistent data was extracted and analysed. Nearly 93.9% of the surveyed population chose putty with a light body as the choice of impression material. 99% of the population agreed the necessity of gingival retraction which dictates the outcome of the treatment. Majority chose Resin modified glass ionomer cement (RMGIC) as the best luting cement that accounted for the majority for retention. The knowledge, awareness level, and their application in clinical practice showed significant variation. Within the limits of this study, the highest predominance of impression material to record the best of the preparation is by the use of putty with light body, 99% of the students opted for gingival cord playing a major role in marginal fit of fixed partial dentures. These were assessed along with other factors that might affect the accuracy of marginal fit and also the consequence of an improper fit was assessed.
