This article will describe how a hard tissue laser is used in various restorative procedures. The erbium family of lasers (Er,Cr:YSGG and Er:YAG) are highly absorbed in water and, to a lesser extent, in tooth mineral. Because a carious lesion contains significantly more water than healthy enamel or dentin, the laser can offer some selectivity in removing the diseased material. Furthermore, thes...

OBJECTIVES Odontoblasts are highly differentiated post-mitotic cells, which under pathological conditions such as carious lesions and dental injuries may degenerate and be replaced by other pulp cells. We have recently shown that this physiological event can be reproduced in an in vitro assay system, but is highly modified by the presence of unpolymerized resinous monomers. Our hypothesis was t...

Bacteria that accumulate polyphosphate have previously been shown to dynamically influence the solubility of phosphatic minerals in marine settings and wastewater. Here we show that dental plaque, saliva, and carious lesions, all contain abundant polyphosphate-accumulating bacteria. Saturation state modeling results, informed by phosphate uptake experiments using the model organism Lactobacillu...

BACKGROUND To investigate the influence of chemical and microbiological methods of caries induction on bond degradation of adhesive systems to primary dentin. METHODS Flat dentin surfaces from 36 primary molars were assigned to three groups (n = 12) according to method to induce caries-affected dentin: (1) control (sound dentin); (2) pH-cycling; and (3) microbiological caries induction model....

According to the findings of various authors, almost 100% world's population suffers from dental caries. Carious lesions cervical area teeth attract special attention since their localization does not provide for early detection pathological process, and features microbiocenosis oral cavity structural enamel-cementum-dentine junction are significant risk factors development progression The aim ...

OBJECTIVE To compare the root carious lesion arrest of chlorhexidine (CHX) and silver diamine fluoride (SDF) varnishes and/or sodium fluoride rinses (NaF) in vitro. BACKGROUND Effective and easily applicable interventions for treating root carious lesions are needed, as these lesions are highly prevalent amongst elderly individuals. METHODS In 100 bovine dentin samples, artificial root cari...

The resin-dentin interface of in vivo specimens restored with the All-Bond 2 system by use of a total-etch wetbonding technique on vital deep human dentin was investigated by: (a) SEM examination of cryofractured specimens; (b) SEM examination of acid-rinsed, highly polished, embedded specimens; and (c) TEM examination of demineralized ultrathin sections. Ultrastructural features that were pert...
