“…(Figure 2) This finding was parallel to the findings in the study by Baker, et al,24 but not with other studies 25-27. (Table 4) A root surface that has been exposed to the pocket environment for a long time becomes hypermineralized, meaning that the mineral content is increased 28-30. It may be because of this reason that we were not able to observe the removal of smear layers with EDTA application in our specimens.…”

Background: Periodontal regeneration is dependent on the uninterrupted adhesion, maturation and absorption of fibrin clots to a periodontally compromised root surface. The modification of the root surface with different agents has been used for better fibrin clot formation and blood cell attachment. It is known that Er:YAG laser application on dentin removes the smear layer succesfully.Aim: The aim of this study is to observe blood cell attachment and fibrin network formation following ER:YAG laser irradiation on periodontally compromised root surfaces in comparison to chemical root conditioning techniques in vitro.Materials and methods: 40 dentin blocks prepared from freshly extracted periodontally compromised hopeless teeth. Specimens were divided in 5 groups; those applied with PBS, EDTA, Citric acid and Er:YAG. They were further divided into two groups: those which had received these applications, and the control group. The specimens were evaluated with scanning electron microscope and micrographs were taken. Smear layer and blood cell attachment scoring was performed.Results: In the Er:YAG laser applied group, smear layer were totally removed. In the blood applied specimens, better fibrin clot formation and blood cell attachment were observed in the Er:YAG group. In the group that had been applied with citric acid, the smear layer was also removed. The smear layer could not be fully removed in the EDTA group.Conclusion: Er:YAG laser application on the root dentin seems to form a suitable surface for fibrin clot formation and blood cell attachment. Further clinical studies to support these results are necessitated.

“…Exposure to crevicular fluid, as well as to enzymes and metabolites produced by subgingival plaque bacteria induces physical and chemical alterations on root cementum. Periodontitis-affected root surfaces are hypermineralized (1)(2)(3), contaminated with bacterial plaque (4) and other cytotoxic substances (5).…”

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.

“…Perhaps deep within the periodontal pocket, it is the organic phase of cementum that is affected by periodontal disease, but not the mineral phase as shown in various other studies. [171819202122] Presence of minerals such as Cu, Zn and Mg are normal inorganic structures found in cementum of diseased and non-diseased root. This observation is in consistent with findings obtained by Barton and Van Swol,[23] which stated that any differences in the elements concentration noted within the root structure could be due to the concentration of these ions in body fluids during tooth formation.…”

Aim:A randomized controlled clinical study was undertaken to evaluate the effectiveness of scaling and root planing (SRP) by using Magnifying Loupes (ML) and dental operating microscope (DOM).Materials and Methods:A total of 90 human teeth scheduled for extraction from 18 patients aged between 25 and 65 years suffering from generalized chronic severe periodontitis were randomly assigned to three treatment groups. Group 1 consisted SRP performed without using magnification (unaided), Group 2-SRP with ML and Group 3-SRP with DOM. Following extractions, samples were prepared for (i) evaluation of surface topography by atomic force microscopy, (ii) presence of smear layer, debris by scanning electron microscopy (iii) elemental analysis by energy dispersive X-ray analysis. Data was subjected to statistical analysis using analysis of variance, post-hoc (Tukey-HSD) and Chi-square test.Results:Statistically significant (P < 0.001) difference was found among the different treatment groups. Group 3 was the best while Group 1 was the least effective technique for SRP. Order of efficacy in terms of the surface was found to be - Palatal < Lingual < Distal ≃ Mesial < Buccal. Efficiency in mandibular to maxillary teeth was found to be significant (P < 0.05), also anterior to posterior teeth (P < 0.05).Conclusion:Magnification tools significantly enhance the efficacy of supragingival and subgingival SRP.
