Article Synopsis
- A study in Pakistan looked at how empathetic dental students are and used a special questionnaire called the Jefferson Scale of Empathy to measure it.
- The study included 304 students from different years in dental school, and they found that female students were more empathetic than males, and third-year students scored the highest for empathy.
- Overall, the questionnaire was found to be reliable, meaning it worked well for measuring empathy, and the results matched what the creators expected.
Objective: To compare the microleakage around resin modified glass ionomer cement (RMGIC) based sealants and flowable resin based sealants placed with or without ameloplasty in extracted human teeth.
Methods: This in-vitro experimental study was conducted at the Operative Dentistry Department, Dow University of Health Sciences, Karachi, Pakistan from June 2017 to December 2018. Sixty extracted human molars and premolars were assigned to four groups (n=15) each, according to the type of fissure sealant (flowable resin based sealant or resin modified glass ionomer based sealant) used and either placed with or without ameloplasty.
Objective: To determine the accuracy of working length measurement with endomotor having builtin apex locator by comparing it with periapical radiographs.
Methods: The cross-sectional study was conducted at the Department of Operative Dentistry, Dr Ishrat-ul-Ibad Khan Institute of Oral Health Sciences, Dow University of Health Sciences, Karachi, from January to June 2014, and comprised permanent maxillary anterior teeth with mature apices. A preoperative radiograph was taken by using standardised paralleling technique.
Background: This study was conducted to compare the adaptation of resin-based sealants with that of Resin modified glass ionome-based sealants in various tooth fissure morphologies.
Methods: It was an in vitro experimental study done at the Dow University and NED University, Karachi, Pakistan. Ten extracted human molars were randomly assigned to two groups, (n=5) each.

In Vitro Comparative Study of Two Different Bleaching Agents on Micro-hardness Dental Enamel.
J Coll Physicians Surg Pak
February 2016
Objective: To evaluate the effect of home-use bleaching agent containing 16% Carbamide Peroxide (CP) and in-office bleaching agent containing 38% Hydrogen Peroxide (HP) on enamel micro-hardness.
Study Design: An in vitroexperimental study.
Place And Duration Of Study: Department of Operative Dentistry and Science of Dental Materials at Dr.
Objective: To evaluate the sealing ability of two different types of Glass Ionomer Cements (GICs) used for sandwich restorations and assess the effect of acid etching of GIC on microleakage at GIC-resin composite interface.
Study Design: Experimental study.
Place And Duration Of Study: Department of Operative, DIEKIOHS (DUHS) and NED University, Karachi, from February to June 2011.
Purpose: To examine the effect of apple and orange juices on the surface hardness of direct tooth-colored restorative materials.
Materials And Methods: The materials included resin-modified glass ionomer cement (Vitremer 3M™ ESPE™ Core buildup restorative) and composite resin (Filtek™ 3M™ ESPE™ Z350). A total of 45 disks of each restorative material were prepared.
Objective: To estimate the microhardness of glass ionomer cement (vitrofil) and resin modified glass ionomer cement (vitremere) in the presence and absence of different surface protections.
Study Design: An in-vitro experimental study.
Place And Duration Of Study: The Department of Operative Dentistry, Dr.
Objective: To determine the microhardness and depth of cure of nanocomposite using different irradiation times on both upper and lower surfaces of composite material.
Study Design: In-vitro experimental study design.
Place And Duration Of Study: Dr.
