OBJECTIVE Severely fluorosed and heavily discolored teeth that have large enamel defects give rise to esthetic concerns and require permanent treatment. In such cases, restorative techniques such as porcelain or composite laminate veneers or crowns are generally preferred, in which tooth preparation is inevitably required. MATERIALS AND METHODS This clinical report describes a patient with se...

Cleidocranial dysplasia (CCD), is an autosomal dominant disorder with a prevalence of 1 in 1,000,000 individuals. It is generally characterized by orofacial manifestations, including enamel hypoplasia, retained primary teeth, and impacted permanent and supernumerary teeth. The successful treatment involving a timing intervention (orthodontic-maxillofacial surgeons-restorative) is already descri...

objectives: this study aimed to determine the effect of surface treatments such as tooth reduction and extending the etching time on microtensile bond strength (µtbs) of composite resin to normal and fluorotic enamel after microabrasion. materials and methods: fifty non-carious anterior teeth were classified into two groups of normal and fluorotic (n=25) using thylstrup and fejerskov index (tfi...

objective: removal of enamel superficial layer during microabrasion treatments may adversely affect sealing ability of the restorative materials. the aim of this study was to measure the effect of different periods of enamel microabrasion on the microleakage of class v glass-ionomer restorations. methods: this in vitro experimental study was conducted on 96 class v cavities which had been prepa...

The present study evaluated transenamel and transdentinal penetration of hydrogen peroxide during tooth whitening recognized in altered enamel by the presence of cracks or microabrasion. We used 72 experimental units (n=20) obtained from bovine incisors: GI-sound enamel; GII-teeth showing visible enamel cracks (4 mm to 5.7 mm in length); and GIII-microabrasioned enamel. The 12 remaining specime...

Objective: Having in mind the growing value that is given to esthetic procedures it has been carried out a literature review about main polemics goes around Enamel Microabrasion technique. Action mechanism: microabrasion compound modifies light refraction and reflection indexes producing an optical effect which allows camouflage of subsurface stains. Indications: technique indicated remove any ...

statement of the problem: demineralization of enamel adjacent to orthodontic appliances frequently occurs, commonly due to insufficient oral hygiene. purpose: the aim of this study was to compare two microabrasion techniques on improving the white spot lesions as well as subsequent enamel discoloration. materials and method: sixty extracted premolar teeth without caries and hypoplasia were sele...

The aim of this study was to measure the effect of different periods of enamel microabrasion on the microleakage of class V glass-ionomer restorations.

OBJECTIVES This study aimed to assess the effect of applying casein phosphopeptide- amorphous calcium phosphate (CPP-ACP) paste, casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) paste and sodium fluoride gel on surface microhardness of enamel after microabrasion. MATERIALS AND METHODS Thirty freshly extracted human premolars were selected. All samples were subjected to ha...

This article describes a novel approach to treat smooth-surface white spot lesions micro-invasively. The technique is based on the infiltration of enamel caries lesions with low-viscosity light-curing resins called infiltrants. After the surface layer is eroded, the lesions are desiccated and a resin infiltrant is applied. The resin penetrates into the lesion micro-porosities driven by capillar...
