“…Despite the somewhat negative findings in our and previous studies regarding ozone treatment on DH, the powerful oxidising property of ozone might contribute to the treatment of DH, but with a different mode of action. Abdelaziz et al [9], suggested that ozone treatment of exposed dentin removes smear layers, opens up the dentinal tubules, broadens their diameter and facilitates the entrance of minerals. Mineral and substance both from saliva or from other desensitising agents, for example calcium and fluoride ions, enter the tubules easily and deeply effectively plugging the dentinal tubules and preventing the fluid exchange through these tubules.…”

“…One interesting, novel approach may therefore be the use of ozone treatment in DH. In spite of promising results in the laboratory, where ozone has been suggested to enhance tubular occlusion and act as desensitizing agent [9], few clinical studies have been conducted to test the efficacy of this technology [10-12] . The aim of this single blind, randomised controlled clinical trial was therefore to investigate the effect of ozone treatment on DH.…”

Background:Dentin hypersensitivity (DH) is a frequent condition in adults and difficult to treat. The aim of this single-blind, randomised controlled clinical trial was to investigate immediate and long-term effect of ozone treatment (Prozone, W&H NORDIC AB) for 12 seconds on hypersensitive teeth compared to placebo treatment, using a split-mouth design.Methods:26 patients (12 M, 14 F, mean age 44+ 2) were included in the study having at least two teeth with confirmed DH in different quadrants of the dentition (each subject had one test and one control tooth). A visual analogue scale (VAS) was used to measure the patients´ pain perception immediately and at a long-term follow-up three months later.Results:Significant reduction in pain perception from DH surfaces was demonstrated from ozone treated test teeth as well as in placebo treated control teeth. We found a moderate (16.2%) but significant pain relief (p< 0.012) over time in 57.7% of all treated teeth.Conclusion:Results from this study confirm previously published results showing no significant effect of ozone treatment on hypersensitive teeth compared to placebo treatment.

Objective:The cytocompatibility of a new ozonized olive oil toward immortalized human gingival fibroblasts (HGFs) was evaluated and compared with two common antimicrobial agents based on chlorhexidine digluconate (CHX).Materials and Methods:The cytocompatibility of the samples was tested on immortalized HGF-1 cells by 3-(4, 5-dimethyl thiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) assay. The cells were incubated for 2 or 24 h with increasing dilution of ozonized olive oil or CHX agents. The percentage of viable cells was calculated relative to control cells set to 100%.Results:The ozonized olive oil is cytocompatible, and the viability values of the cells treated for 2 or 24 h with increasing concentrations of ozonized olive oil were significantly higher (P < 0.01) compared with the values obtained using CHX.Conclusions:The present data demonstrate that due to its cytocompatibility, the new ozonized olive oil could be considered an alternative antibacterial agent.

“…[ 5 ] However, these crystals are small in size and hence not effective in occluding the tubules. [ 2 ] This may be the reason for the significantly lesser depth of penetration of NaF (154.09 ± 25.16 μm) when compared to Groups 3 and 4. Similar results were obtained by Raafat Abdelaziz et al .,[ 2 ] who showed that fluoride treated specimens displayed significantly lower percentage of tubule occlusion compared to other experimental groups.…”

“…Dentin hypersensitivity is a commonly encountered, painful clinical condition for which no consistent remedy has been established. [ 1 2 ] Although various theories have been put forward over the years to explain the physiological mechanism behind this problem, hydrodynamic theory of dentinal sensitivity remains the most accepted theory till date. [ 3 ] Stimuli such as heat, cold, evaporation, osmotic, and pressure changes cause fluid movement within the dentinal tubules, thereby inducing sharp pain responses in the nerve fibers.…”

Evaluation of dentinal tubule occlusion and depth of penetration of nano-hydroxyapatite derived from chicken eggshell powder with and without addition of sodium fluoride: An in vitro study

Aim:This in vitro study evaluated the degree of dentinal tubule occlusion and depth of penetration of nano-hydroxyapatite (nHAp) derived from chicken eggshell powder with and without the addition of 2% sodium fluoride (NaF) using scanning electron microscope (SEM) and confocal laser scanning microscope (CLSM).Materials and Methods:nHAp was synthesized and characterized using X-ray diffraction and SEM-energy dispersive spectroscopy. Dentin discs were obtained from extracted teeth, pretreated with 17% ethylenediaminetetraacetic acid for 5 min and were divided into four groups based on the experimental agents as follows: Group 1: Untreated (control), Group 2: 2% NaF, Group 3: nHAp, Group 4: Combination of nHAp and 2% NaF. The treatment protocol was carried out for 7 days, after which the specimens were viewed under SEM and CLSM.Statistical Analysis Used:One-way ANOVA and Tukey's post hoc multiple comparison tests (P < 0.05).Results:All the experimental agents occluded the dentinal tubules, but to varying degrees and depths. Specimens treated with the combination of nHAp and 2% NaF showed complete dentinal tubular occlusion and significantly greater depth of penetration than those treated with nHAp and 2% NaF alone.Conclusion:The combination of nHAp and 2% NaF was the most effective in occluding dentinal tubules.

Tubular occlusion of simulated hypersensitive dentin by the combined use of ozone and desensitizing agents

Abstract: The use of ozone gas is a viable adjunct to fluoride-containing desensitizers in enhancing tubular occlusion, but is not effective with oxalate desensitizers.
