KNOWLEDGE, ATTITUDE AND PRACTICE AMONG GENERAL DENTAL PRACTITIONERS AND POSTGRADUATE STUDENTS ON INTRAORAL REPAIR OF FRACTURED ZIRCONIA BASED RESTORATIONS IN NAMAKKAL DISTRICT- A QUESTIONNAIRE SURVEY

Restoring lost tooth structure with a material that mimics natural teeth, both in contour and color, is gaining attention among the dentist as well as the patients. One such esthetic material is zirconia. Monolithic Zirconia based restorations are restricted for posterior regions, where mechanical properties are of prime concern and Bilayered Zirconia restorations, are used to achieve better esthetics in the anterior regions. Fracture or chipping of the veneered Zirconia based restorations has been reported clinically and rather than replacing the entire fractured restoration, intraoral repair procedures can be carried out to correct the fractured restoration, which are proven scientifically. Many intraoral repair systems are available in the market. Dentist should have in depth knowledge and awareness on how and when to use the intra oral repair system for each case, which will prevent the need for fabricating a new restoration. Thus the aim of this study is to assess the Knowledge, Attitude and Practice among general dental practitioners and postgraduate students on intraoral repair of fractured zirconia based restorations in Namakkal district.
