Effects of pH on the dentin surface.

A microleakage and scanning electron microscope (SEM) study was conducted in order to investigate the effects of acidic primers on prepared dentin surfaces. The microleakage study revealed that no significant differences were noted between the five materials tested in regard to leakage at enamel and dentin margins. SEM analyses revealed that the smear layers of all specimens were altered in some manner. Further long-term clinical studies should be conducted to evaluate acidic treatment of dentin.

Composite Resins↗

Blending incremental and stratified layering techniques to produce an esthetic posterior composite resin restoration with a predictable prognosis.

Composite resin restorations play an ever-increasing role as routine restorations in everyday clinical practice. However, the long-term prognosis of these restorations is still widely debated and open to question. The restorative protocols are still evolving, whether for direct or indirect placement, and little evidence is available in the scientific literature as to the ideal choice of site, technique, and category for placement. This article discusses the problems encountered and suggests a clinical restorative protocol to optimize composite resin placement.

Acid etching of a glass ionomer cement base: SEM study.

The effects of acid-etching duration on the surface of a glass ionomer cement designed for use as an intermediary layer between composite resin and dentine were investigated. Cement topography changes occurred which could be related to etch duration. When compared with enamel etched for a similar period, undue loss of cement substance was not observed for any of the etch times used.

Paediatric dentistry: coronal radiolucency. Case reports.

Cases have been reported in the literature in which a coronal defect has been noted in unerupted permanent teeth. This paper reports on two cases which were treated by professional intervention. Knowledge of the existence of this condition, early recognition of its radiographic characteristics, and appropriate treatment is a major factor in achieving a successful outcome.
