The aim of the present study was to evaluate the effect of fluoride in prevention of tooth erosion around orthodontic brackets under erosive challenge. Edgewise brackets were bonded with Transbond™ XT composite on vestibular surface of 40 bovine incisors. The teeth were assigned to 4 groups (n=10): G1: Remineralizing saliva; G2: Erosive challenge; G3: Experimental group submitted to topical app...

OBJECTIVE Dental erosion is characterized as a disorder with a multifactorial aetiology including environmental acid exposure. The purpose of this article was to summarize and discuss the available information concerning occupational dental erosion. METHODS Information from original scientific papers, case reports and reviews with additional case reports listed in PubMed, Medline or EMBASE [s...

Regressive changes are a group of retrogressive changes of teeth which occur due to nonbacterial causes resulting in wear and tear of tooth structures with impairment of function. Studies1-12 on the mechanism of stress concentration in cervical areas concluded that occlusal loading forces result in tooth flexures which lead to mechanical microfractures and loss of tooth structure in the cervica...

Characterisation of the electrostatic properties of dental enamel is important for understanding the interfacial processes that occur on a tooth surface and how these relate to the natural ability of our teeth to withstand chemical attack from the acids in many soft drinks. Whereas, the role of the mineral component of the tooth enamel in providing this resistance to acid erosion has been studi...

OBJECTIVE The objective of the study was to evaluate the effectiveness of chitosan and chitosan-ethylenediamine tetraacetic acid (EDTA) (3:1,1:1,1:3) in comparison with 5.2% sodium hypochlorite (NaOCl) in disinfecting Enterococcus faecalis biofilm on root canal dentin and in the removal of smear layer with minimal erosion. MATERIALS AND METHODS Seventy single-rooted extracted human mandibular...

INTRODUCTION: several cases of tooth erosion have been attributed to oral administration of liquid oral medications. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has gained much concern in modern dentistry for having antierosive properties. OBJECTIVES: The aim of the study was to evaluate the effect of CCP-ACP on the surface microhardness of primary tooth enamel eroded by antihis...

Enamel proteins form a scaffold for growing hydroxyapatite crystals during enamel formation. They are then almost completely degraded during enamel maturation, resulting in a protein content of only 1% (w/v) in mature enamel. Nevertheless, this small amount of remaining proteins has important effects on the mechanical and structural properties of enamel and on the electrostatic properties of it...

Various fruit juices with relatively low pH are known to have erosive effects on human tooth enamel in a reasonably short time. Honey, also with a relatively low pH, could do the same, but scanning electron microscopy showed no erosion of enamel by honey over a period of 30 min, neither did Knoop microhardness tests show any deterioration of enamel structure. The absence of any effect could be ...
