The objective of this study was to assess the post-operative sensitivity of posteriorresin-basedcomposite in Class I cavities of different sizes with two placement techniques.
It was a Quasi Experimental study. Sample size was 131 patients with two Class I cavities (depth between 3-4 mm) in molar teeth (ipsilateral or contralateral). Two molars in the same patient were restored with posterior composite (QuixfilDentsplyDetrey) using bulk and incremental placement techniques respectively. The patients were recalled at day 7 post-operatively and 2 item questionnaires were used to record the presence and absence of sensitivity that was triggered by cold and hot stimuli. Data was collected using data collection proforma.
Data was analyzed with SPSS for windows using McNemar chi-square test.
Incremental and bulk placement techniques showed statistically significant difference for the occurrence of post-operative sensitivity for cold (p- value < 0.002) and hot (p-value<0.001). The chi-Square test was applied to analyze post-operative sensitivity in both techniques with different cavities sizes. The result was significant with p-value <0.0001.
The incremental technique was found to be superior to bulk placement technique in preventing post-operative sensitivity in class 1 cavities of various sizes.
