Root conditioning in periodontology - Revisited

Abstract

Objective:Root surfaces of periodontitis-affected teeth are hypermineralized and contaminated with cytotoxic and other biologically active substances. To achieve complete decontamination of the tooth surfaces, various methods including root conditioning following scaling and root planning are present. The main objective of this article is to throw light on the different root conditioning agents used and the goals accomplished by root conditioning in the field of periodontology.Materials and Methods:20 human maxillary anterior teeth indicated for extraction due to chronic periodontitis were collected and root planned. The teeth were sectioned and specimens were divided into two groups — Group I and II. Group I dentin specimens were treated with EDTA and group II specimens were treated with tetracycline HCl solution at concentration of 10% by active burnishing technique for 3 minutes. The root surface samples were then examined by scanning electron microscope (SEM).Results:The results of the study showed that EDTA and tetracycline HCl were equally effective in removing the smear layer. It was observed that the total and patent dentinal tubules were more in number in teeth treated with tetracycline as compared to EDTA group. However, EDTA was found to be much more effective as root conditioning agent because it enlarged the diameter of dentinal tubules more than that of tetracycline HCl.Conclusion:Results of in-vitro study showed that both the agents are good root conditioning agents if applied in addition to periodontal therapy. However, further studies are required to establish the in-vivo importance of EDTA and tetracycline HCL as root conditioners.

Green synthesis of silver nanoparticles using water extract of Salvia leriifolia: Antibacterial studies and applications as catalysts in the electrochemical detection of nitrite

“…From the Figure 5b, we can see that the S.l-AgNPs have the average diameter of 27 nm, which is much smaller than that of the previously reported papers. [10,11] 3.6 | Electrochemical characteristics of S. l-AgNPs…”

“…[10] The uses of the microorganisms to the green synthesis of silver nanoparticles also reported. AgNPs have been synthesized by bacteria of Staphylococcus aureus [11] and Bacillus megaterium. [12] In addition, extracellular synthesis of AgNPs have been carried out using fungus of Aspergillus clavatus.…”

Does chemical preconditioning contribute to the effectiveness of scaling and root planing? An in vitro pilot investigation

“…Several studies demonstrated the influence of SRP combined with various conditioning agents, such as citric acid, EDTA or tetracycline hydrochlorite on smear layer removal, diameter alteration of dentinal tubules and on the dentin collagen matrix using SEM approach (16,17). These results indicate that root conditioning after SRP is favourable for smear layer removal as well as in exposing the collagen matrix (18).…”

The difference of saline and sterile water for tetracycline hydrochloride solvents in cementum demineralization

“…This may ultimately achieve an optimal degree of demineralization within a short period of time, in comparison to other application modes. 18 Results of this study are discussed below on the percentage of smear layer and the collagen structure exposed cementum. Control group showed there is no apparent effect on the smear layer after scaling and water irrigation.…”
