Post-operative sensitivity of Class I, II amalgam and composite resin restorations: Clinical evaluation in an undergraduate program

Abstract

Aim:The aim was to evaluate the post-operative sensitivity (POS) of composite and amalgam restorations performed by 4 th and 5 th grade undergraduate dental students (under supervision) at Syrian Private University, and determine the possible relationship between POS and restorative material type, preparation depth, and cavity classifi cation. USPHS sensitivity evaluation was done after 24 h, 1 week, 1 month, and 2 months. Results: POS for amalgam restorations (18.1%) was higher than composite restorations (9%) in all periods (P < 0.05). A statistically insignifi cant higher sensitivity was observed in Class II (16.9%) compared with Class I (13.3%) in all periods (P > 0.05). POS in deep preparations (22.6%) was higher than medium (14.6%) and shallow (8.8%) depth preparations in all periods (P < 0.05). Regardless of restoration type, POS appeared in 36.5% after 1 day and it was decreased till almost disappeared after 2 months. Conclusions: (1) POS for amalgam restorations was more than composite restorations. (2) Cavity design has no infl uence over POS. (3) The more the cavity depth, the more the POS. (4) POS decreased within time.

A Comparative Evaluation of Postoperative Sensitivity Between Cention-N and Resin-Modified Glass Ionomer Cement in Class V Cavity: An In Vivo Study

“…To overcome these disadvantages of conventional GIC, recently advanced material in generating GIC is resin-modified glass ionomer cement (RMGIC). This material has been created to enhance the material's physical qualities and may benefit patients [14]. Compared to traditional GIC, RMGIC offers several benefits, including prolonged working time, enhanced setting time, adequate marginal seal, fluoride release, superior aesthetics, and higher strength [15].…”
