Bisphenol A in dental materials – existence, leakage and biological effects [PDF]
Objective: Recently, questions have been raised concerning the potential endocrine disrupting effects of bisphenol A (BPA). This substance is a constituent in many different products which we frequently come into contact with, such as food containers and

Oral chemical ulceration due to iatrogenic hydraulic oil leakage from the dental unit of a surgical handpiece: A case report [PDF]
Key Clinical MessageOral chemical ulceration is a rare condition. The causes differ from misuse of dental material by dentists and over‐the‐counter drugs (OTC) to the herbal ingredients in our foods. Detailed patient history helps to explore the diagnosis and further management of such a lesion, which extend from no intervention in mild cases to ...

A study on the leakage of mercury vapor from pre-capsulated dental amalgam according to storage temperature [PDF]
Objective: The aim of this study was to measure the amount of mercury vapor from one pre-capsulated dental amalgam according to the storage temperature and to investigate whether the storage temperature suggested by the manufacturer or ISO is appropriate for the storage.Materials and Methods: GK Amalgam and Ultracaps+ were used in this study.

The use of micro-CT with image segmentation to quantify leakage in dental restorations [PDF]
To develop a method for quantifying leakage in composite resin restorations after curing, using non-destructive X-ray micro-computed tomography (micro-CT) and image segmentation.Class-I cavity preparations were made in 20 human third molars, which were divided into 2 groups. Group I was restored with Z100 and Group II with Filtek LS.

Marginal Leakage Around Fixed Dental Prosthesis - A review
Marginal leakage is the intrusion into the space between all the restorative materials and cavity walls of fluids, bacteria, and ions. It can cause irritation of the pulp, change of color in the tooth and secondary caries, and may also result in restoration failure. The freshly placed prosthetic margins invariably leak.

Bacterial leakage around dental restorations: its effect on the dental pulp [PDF]
This study revealed that the quantity of bacteria filtered from the base of Class V cavity restorations were directly related to the type of medicament used. Of the brands studied: composite, amalgam, silicate, and guttapercha – each produced varying numbers of bacterial colonies, whereas zinc oxide and eugenol cement showed none. Histopathology of the

Validation of a method of quantifying 3D leakage in dental restorations
A reliable and validated protocol for nondestructive analysis of the entire restorative interface that could be applicable in studies assessing the adaptation of direct and indirect restorations is lacking.The purpose of this in vitro study was to validate a 3D protocol for microleakage assessment in class II mesio-occluso-distal (MOD) cavities ...

Comparative Study on the Effect of Various Implant-Abutment Connections on Microbial Leakage
Background: Microbial leakage at the implant-abutment interface can lead to peri-implantitis, jeopardizing the long-term success of dental implants. The design and type of implant-abutment connection play a significant role in minimizing this leakage ...

Evaluation of dental composite shrinkage and leakage in extracted teeth using X-ray microcomputed tomography [PDF]
Use X-ray microcomputed tomography (microCT), to test the hypothesis that composite shrinkage and sites of potential leakage in human teeth are non-uniformly distributed and depend on cavity geometry and C-factor.Two holes of equal volume but different dimensions were drilled into the exposed dentin of extracted human molars.

Comparing the marginal leakage and retention of implant‐supported restorations cemented by four different dental cements [PDF]
AbstractBackgroundDespite the wide use of implants in dentistry, there is insufficient information about the ideal cement for retention.PurposeTo determine the cement bond strength and marginal leakage of crown and partial denture cemented to implant abutments by four different types of cement.Materials and MethodsEighty‐four direct abutments were ...
