In Class-1 Amalgam Restorations Postoperative Sensitivity Administration Assessing Effectiveness Among Bonded Amalgam - The Use of Conventional Amalgam Restoration and Cavity Varnish: A Clinical Study

Abstract

Objective: To evaluate the lining material which responsible for reduced post-operative sensitivity between cavity varnish, conventional silver amalgam and bonded amalgam filling class-1 amalgam restoration.
 Materials and Methods: Present study was conducted at University of Lahore during the period from February, 2016 to December, 2016. After oral examination, 51 patients were included who have cavity (black class-1) in mandibular molars divided the selected patients into three groups. Amalgam filling got by group-1 with zinc phosphate and amalgam restoration got by group-2 with coating of cavity varnish. Bonded amalgam restoration was given to group-3.
 Results: The outcomes dismissed the invalid hypothesis (Ho) which means that similar findings presented by all restorations to reduce the post-operative sensitivity. There is distinction between these restoration methods which was also confirmed by Tukey HSD Test.
 Conclusion: In class-1 cavity, the post-operative sensitivity can be reduced by bonded amalgam restoration. The post-operative sensitivity also positively reduced through cavity varnish use
