The aim of this study was to analyze, under scanning electron microscopy (SEM), the morphologic characteristics of root surfaces after application of Carisolv TM gel in association with scaling and root planing (SRP). Sixty periodontally compromised extracted human teeth were randomly assigned to 6 groups: 1) SRP alone; 2) passive topical application of Carisolv TM + SRP; 3) active topical application of Carisolv TM + SRP; 4) multiple applications of Carisolv TM + SRP; 5) SRP + 24% EDTA; 6) topical application of Carisolv TM + SRP + 24% EDTA. Carisolv TM gel was applied to root surfaces for 30 s, followed by scaling and root planing, consisting of 50 strokes with Gracey curettes in an apical-coronal direction, parallel to the long axis of the tooth. The only exception was group 4, in which the roots were instrumented until a smooth, hard and glass-like surface was achieved. All specimens were further analyzed by SEM. The results showed that the treatment with Carisolv TM caused significant changes in root surface morphology of periodontally compromised teeth only when the chemical agent was actively applied (burnishing technique). Carisolv TM failed to remove the smear layer completely, especially with a single application, independently of the method of application. Multiple applications of Carisolv TM were necessary to achieve a smear layer reduction comparable to that obtained with 24% EDTA conditioning.

“…3 and 6). A similar pattern of deeply tufted collagen fibrils has been observed to result from citric-acid burnishing of a root surface as part of a tissue-regenerative periodontal treatment (Sterrett and Murphy, 1989). The physical rubbing action combined with the chemical action of citric acid was found to enhance the removal of chemically dissolved inorganic dentin material and surface debris, exposing a deeply tufted collagen fibril surface topography, similar to the appearance of a "shag carpet".…”

A TEM Study of Two Water-based Adhesive Systems Bonded to Dry and Wet Dentin

et al. 1998

To keep the exposed collagen scaffold penetrable to resin, it has been recommended that the conditioned dentin surface be maintained in a visibly moist condition, a clinical technique commonly referred to as wet bonding. In this study, resin-dentin interfaces produced with two water-based adhesive systems--OptiBond (OPTI, Kerr) and Scotchbond Multi-Purpose (SBMP, 3M)--were compared by transmission electron microscopy, following the application of either a dry- or a wet-bonding technique. The hypothesis advanced was that the ultramorphology of the hybrid layer would differ depending on which bonding method was applied. A morphologically well-organized hybrid layer of collagen fibrils intermingled with resin in tiny interfibrillar channels was consistently formed by the OPTI system. The SBMP system was found to produce a hybrid layer with a more variable ultrastructure, less distinctly outlined collagen fibrils, and a characteristic electron-dense phase located at its surface. No major differences in hybrid layer ultrastructure were observed when the two adhesive systems investigated were bonded to either dry or wet dentin. When the adhesives were dry-bonded, no ultrastructural evidence of collapsed demineralized collagen, incompletely or not at all infiltrated by resin, could be detected. In addition, when the two adhesives were bonded to wet dentin, no signs of overwetting phenomena, that would have indicated that water was ineffectively removed, were apparent. It has been hypothesized that the amount of water provided with the hydrophilic primer solution of either of the two adhesive systems investigated suffices to re-hydrate and re-expand the gently air-dried and collapsed collagen network. Further research should be directed to determine whether this hypothesized self-rewetting effect can be extrapolated to other adhesive systems that provide water-based primers.

“…[7] Sterrett and Murphy and Trombelli et al have also demonstrated similar findings. [18,28] After conditioning with respective solutions, the specimens were then processed and examined under SEM at ×1500 magnification to evaluate: Efficacy in removal of smear layer, total number of dentinal tubules present per specimen, number of patent dentinal tubules and their diameter.…”
