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...

The research carried out a comparative assessment of the physical and mechanical properties tooth enamel: healthy; demineralized; demineralized subsequently infiltrated with flowable composite according to standard or modified technique. An original in vitro model artificial caries human enamel was used for study, clinical-topographic, color-textural physical-mechanical which correspond charact...

Despite the continuous development of materials and techniques of adhesive bonding, the basic procedure remains relatively constant. The technique is based on three components: etching substance, adhesive system, and composite material. The use of etchants during bonding orthodontic brackets carries the risk of damage to the enamel. Therefore, the article examines the effect of the manner of en...

We describe studies of the interaction of ≅400ns duration, multiline (2.6-3) μm HF laser with enamel tissue. The etch rate experiment showed an ablation threshold fluence of 47 Jcm but using the dispersion theory for optical coefficients of n and k for enamel at dominant laser lines, this value reduced to ≅25 Jcm making it more comparable with other investigations. The main mechanism of enamel ...

STATEMENT OF THE PROBLEM Enamel and dentin marginal sealing ability of the new adhesive materials could play an important role in successful restoration on fluorosed teeth. PURPOSE The aim of this in vitro study was to evaluate the marginal microleakage of low-shrinkage silorane-based composite, nano-ionomer, and methacrylate-based composite through self-etching approach or with enamel acid e...

Poor oral hygiene has been considered one of the main problems routinely faced in the orthodontic treatment. Orthodontic appliance creates an environment that provides mineral loss from the dental enamel. Such condition is clinically seen as white spot lesions and cavitations in the most severe cases. The aim of this study was to evaluate the effects of a fluoride varnish application as a carie...

Objectives This study sought to compare enamel cracks after orthodontic bracket debonding in the surfaces prepared with erbium, chromium: yttrium-scandium-galliumgarnet (Er,Cr:YSGG) laser and the conventional acid-etching technique. Materials and Methods This in-vitro experimental study was conducted on 60 sound human premolars extracted for orthodontic purposes. The teeth were randomly divid...

Sixty-one 14 to 17-year-old White children (2 7 males and 34 females) who were born and had been living continually in Kenhardt were selected for this study. The DM FT and DEGF were determined clinically. Acid etch biopsies were done on both the maxillary central incisors of each pupil. F and Ca analyses were carried out on the biopsy solutions and mass fluoride expressed in picograms (pg) and ...

This article reviews the indications, objectives and step by process of Modified Hall Technique in management primary permanent molars affected severe enamel hypomineralization. Scientific based biological principles are discussed order to provide relevant clinical information for Pediatric General dentists support safe use technique practice.
