Frequency of Post-Operative Sensitivity In Permanent Posterior Teeth with Class I Composite Restorations
Written by Neelum Naz   Published On Issue 1 Vol 8, 2020
Background/objectives: Post-operative sensitivity after placing posterior composite restorations is a problem that clinicians have experienced since 20 years ago even when a dentine liner is used. Sensitivity is associated with increased dentine permeability and with the residual stresses from shrinkage in adhesive composites resin restoration that may cause de-bonding. This study aimed at evaluating the post-operative sensitivity in composite restorations using total etch adhesive system in cla

The Evaluation of Two Different Methods of Acrylic Resin Polymerization
Written by Edit Xhajanka   Published On Issue 1 Vol 8, 2020
Background. During the polymerization and processing procedures of heat-polymerization, polymethyl methacrylate shrinkage of acrylic resin has been noticed. The purpose of the study was to compare two methods of polymerization of acrylic resin: compression molding and injection molding technique. Materials and methods. 167 patients who needed removable denture treatment were examined. Among them, the patients who met the inclusion criteria were selected to be part of our study. Two types of comp

Comparison of Four Indigenous Plastination Techniques for Potential Use As A Teaching Aid In Dentistry
Written by Bhavna Chulliparampil Mohan   Published On Issue 1 Vol 8, 2020
Aim: The present study attempts to plastinate selected oral specimens using four different methods for preserving them in pathology museums. Background: Plastination is a relatively recent technique in which synthetic materials are used for the preservation of bodies and body parts. This process involves the replacement of water and lipids in biological tissues with curable polymers like polypropylene, polyester and epoxy resins which will then harden and finally result in natural-looking, dry a

The Effect of Egf on the Ultrastructure of Submandibular Salivary Glands of Albino Rats Receiving Doxorubicin
Written by Mansy M.   Published On Issue 1 Vol 8, 2020
Objectives: The present study was designed to detect the outcome of EGF injection on the cytotoxic effect of DXR induced in submandibular S.G. of rats regarding its ultrastructure. Methods: 30 male Albino rats, two months old and 200gm body weight were divided into three groups. Group I assisted as a control group. Group II (DXRgp), 20 mg/kg body weight DXR was injected intraperitoneally into the rats. Whereas group III (DXR + EGF) the rats received the same dose of DXR and on the next day, they

Comparative Effect of Contamination and Decontamination of Two Adhesive Systems by Blood and Haemostatic Agent on The Bond Strength to Dentin: In Vitro
Written by Aseel Fareed Faisal   Published On Issue 1 Vol 8, 2020
Aim: This study aimed to detect how blood and haemostatic agent contamination affects the shear bond strength of self-etch and total-etch adhesives to dentin and to compare the difference in bond strength due to contamination and decontamination after adhesive light curing. Materials and Methods: 130 sound wet human molars were used to prepare a flat dentin surface on its buccal side. Randomly, they were divided into 2 groups (n=65) based on the adhesives Group 1: (Prime & Bond Select™

In Vitro Evaluation of Ionized Water as a Potential Endodontic Irrigant
Written by Fahd Aljarbou   Published On Issue 1 Vol 8, 2020
Objective: This study aimed to evaluate the antimicrobial and tissue-dissolving properties of ionized water in comparison with other endodontic irrigants, which were sodium hypochlorite solutions (medical, conventional, and flavored) and two types of oxygen-based solutions.   Methodology: E. faecalis bacteria (ATCC No. 29212) were cultured in a hundred Petri dishes in conjunction with ten types of irrigants placed in disks. The inhibition zone for each sample was measured twice at 24 and 48

Salivary Copper And Zinc Levels In Dental Caries: An Exvivo Study
Written by Nireeksha   Published On Issue 1 Vol 8, 2020
aliva due to its extensive association with all the tissues in the oral cavity seems as potent indicators for various elements. Thus any types of changes in salivary levels of these measurable elements can be considered as potential indicators and biomarkers for occurrence/progression disease condition. The most important trace element that has a role to play in the pathogenesis of dental caries are Ca, Na, Zn, Mg, Fl. Zinc plays a major role in adhesion growth and bacterial activity inhibition,
