Bisphenol A in dental materials – existence, leakage and biological effects [PDF]

open access: goldHeliyon, 2019
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]

open access: goldClinical Case Reports, 2023
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 ...

The use of micro-CT with image segmentation to quantify leakage in dental restorations [PDF]

open access: greenDental Materials, 2015
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.

Bacterial leakage around dental restorations: its effect on the dental pulp [PDF]

open access: greenJournal of Oral Pathology & Medicine, 1982
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

Evaluation of dental composite shrinkage and leakage in extracted teeth using X-ray microcomputed tomography [PDF]

open access: greenDental Materials, 2009
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.

Marginal Leakage Around Fixed Dental Prosthesis - A review

open access: closedInternational Journal of Research in Pharmaceutical Sciences, 2020
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.

Comparative Study on the Effect of Various Implant-Abutment Connections on Microbial Leakage

open access: yesJournal of Pharmacy and Bioallied Sciences
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 ...

Effects of Dental Adhesive Cement and Surface Treatment on Bond Strength and Leakage of Zirconium Oxide Ceramics

open access: bronzeDental Materials Journal, 2008
To evaluate the interactive influence of adhesive materials and surface treatments on bond strength of zirconium oxide ceramics, six types of adhesive resin cements (RelyX ARC (RA), Super-Bond C & B (SB), Linkmax (LM), Panavia Fluoro Cement (PF), Bistite II (BT), and Imperva Dual (ID)), three types of resin-reinforced glass ionomer cements (Xeno Cem ...

In Vitro Bacterial Leakage at the Implant-Abutment Connection of Two Dental Implant Systems with Internal Connection

open access: goldFrontiers in Dentistry, 2021
Objectives: Bacterial leakage at the implant-abutment interface is one of the main causes of peri-implant inflammation. One of the factors that influences bacterial leakage is the structural design of the interface. Considering the limited studies that have examined slip-joint connections, a comparative study of bacterial leakage was performed on two ...

Effect of Electrodeposited Gold Coatings on Micro-Gaps, Surface Profile and Bacterial Leakage of Cast UCLA Abutments Attached to External Hexagon Dental Implants [PDF]

open access: goldCoatings, 2023
Purpose: The objective of the study was to qualitatively assess the micro-gap dimensions, connecting fitting surface profile, and bacterial leakage of cast high-gold-alloy UCLA abutments, with or without electrodeposited gold coatings attached to external hexagon implants. Materials and methods: Sixteen plastic UCLAs (PUCLAs) were cast with a high-gold-
