RESUMEN

OBJECTIVE: The aim of the study was to review the available literature on the application of oxygen-ozone therapy (OOT) in the treatment of low back pain (LBP), to understand its therapeutic potential and compare it with other available treatment options. MATERIALS AND METHODS: A systematic review was performed on the PubMed and Scopus databases, with the following inclusion criteria: (1) randomized controlled trials (RCTs), (2) published in the last 20 years, (3) dealing with OOT in patients with LBP and herniated disc, (4) comparing the results of OOT with those of other treatments. The risk of bias was assessed by the Cochrane Risk of Bias tool. RESULTS: Fifteen studies involving 2597 patients in total were included. Patients in the control groups received different treatments, from oral drugs to other injections, instrumental therapy and even surgery: corticosteroids were used in 5 studies, analgesic therapy in 2 studies; placebo, microdiscectomy, laser-therapy, TENS and postural rehabilitation, percutaneous radiofrequency intradiscal thermocoagulation and psoas compartmental block were tested in the other trials. Looking at the quality of the literature, none of the studies included reached "good quality" standard, 3 were ranked as "fair" and the rest were considered "poor". Comparison of OOT results with other approaches showed that, in the majority of studies, OOT was superior to the control treatment, and also when compared to microdiscectomy, ozone showed non inferiority in terms of clinical outcomes. CONCLUSIONS: The analysis of literature revealed overall poor methodologic quality, with most studies flawed by relevant bias. However, OOT has proven to be a safe treatment with beneficial effects in pain control and functional recovery at short to medium term follow-up.

RESUMEN

INTRODUCTION: The aim of this study was to compare the effect of different application techniques of ozone on the prevalence of postendodontic pain in patients undergoing single-visit root canal treatment. METHODS: hundred eight patients with necrotic pulp in single-rooted teeth and apical periodontitis participated in the trial. A standard single-visit endodontics protocol was followed with 5.25% sodium hypochlorite and rotary nickel-titanium files. After shaping and cleaning, patients were randomly allocated into the following groups: group 1 (n = 21), ozone treatment with no activation (NA); group 2 (n = 22), ozone treatment with manual dynamic activation (MDA); group 3, (n = 21), ozone treatment with passive ultrasonic activation (PUA); group 4 (n = 23), ozone treatment with sonic activation (SA); and group 5 (n = 21), no ozone treatment (the control group). Patient levels of discomfort were recorded at 6 different time intervals using the visual analog scale (VAS). Comparison of the mean difference between the groups and time intervals was performed using 2-way analysis of variance followed by a post hoc Bonferroni test. The level of significance was set at 5%. RESULTS: VAS scores were highest for the control > NA > MDA > SA > PUA groups. A statistically significant reduction in VAS scores was observed in the PUA and SA groups in comparison with the NA, control, and MDA groups. Timewise comparison showed a highly significant decline in VAS scores at all time intervals (P < .001). CONCLUSIONS: Ultrasonic and sonic activation of ozone resulted in less pain in patients undergoing single-visit endodontics compared with no ozone treatment.

RESUMEN

BACKGROUND: Results from several randomized controlled trials have shown a beneficial effect of ozone in reducing postsurgical complications after impacted mandibular third-molar surgery, but the literature is lacking a systematic review and meta-analysis. METHODS: The authors conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines after exclusion and inclusion criteria were applied and the following outcome parameters were evaluated: pain, swelling, trismus, quality of life, number of analgesics consumed, and adverse events. RevMan Cochrane Collaboration software, Version 5.3, was used to perform meta-analysis and the Grading of Recommendation Assessment, Development and Evaluation approach was used to rate the certainty of evidence. RESULTS: Patients who underwent adjuvant ozone application reported lower pain scores than patients in the control group at 24 hours after surgery (95% CI, -3.94 to -1.56) and at 7 days (95% CI, -1.67 to -0.78). Pooled analysis of all 4 included trials revealed a standardized mean difference (SMD) in swelling of -0.44 at 24 hours, 0.63 at 72 hours, and -0.87 at 7 days after surgery in the experimental group. Higher mean estimates in mouth opening were experienced by patients who received ozone at 24 hours (SMD, 2.74; 95% CI, -1.93 to 7.41; 4 studies, 133 patients), 72 hours (SMD, 2.77; 95% CI, -0.63 to 6.17; 4 studies, 133 patients), and 7 days after surgery (SMD, 1.42 SMD; 95% CI, -1.34 to 4.18; 4 studies, 133 patients). PRACTICAL IMPLICATIONS: Evidence suggests that adjuvant ozone application can offer some benefit for reducing pain, improving quality of life, and decreasing mean intake of analgesics after impacted mandibular third-molar surgery, but it is not effective in reducing facial swelling and trismus, which paves the way for future research.

RESUMEN

OBJECTIVE: Periodontitis is a chronic inflammatory disease initiated by dysbiotic microbiota. Conventional mechanical debridement often needs adjunctive measures to control the disease process. The objective of the present study was to find out benefit of ozonized water irrigation along with nonsurgical periodontal therapy for the management of periodontitis. METHODS: We have conducted a randomized controlled, triple-blinded, parallel-group clinical trial. The test group (n = 25) was treated with ozonized water irrigation, whereas the control group (n = 25) received normal saline irrigation along with mechanical debridement. Full mouth plaque score, bleeding score, probing pocket depth and clinical attachment loss were evaluated at baseline and 4 weeks after treatment. Salivary interleukin 1 beta was analysed using enzyme linked immunosorbent assay. Analysis of covariance, t test and chi-square test were used for intergroup comparison. Intragroup comparison was done using the paired t test. RESULTS: Adjunctive ozone water irrigation resulted in significant improvement in all clinical parameters, except probing pocket depth after adjusting the extraneous effects due to initial confounding factors (p < 0.001). But as per subgroup analysis, ozone water irrigation resulted in significant reduction in pocket depth in deep pockets (p = 0.01) and the number of sites with a pocket depth ≥4 mm with bleeding on probing. Salivary interleukin 1 beta also reduced significantly in the test group after therapy. CONCLUSION: Ozone irrigation provides adjunctive benefit along with nonsurgical periodontal therapy in reducing clinical parameters and inflammatory mediators in saliva. But long-term benefits need to be assessed with future studies. The study was registered in the Clinical Trial Registry of India (CTRI no: CTRI/2020/06/026275).

RESUMEN

The search for new topical treatments able to display not only antimicrobial properties but also a multiplicity of other beneficial effects while expressing safe cytocompatibility toward host tissues is being progressively developed. Antiseptics represent an aid to the gold standard nonsurgical treatment Scaling-and-Root-Planing (SRP) for periodontal disease. This split-mouth study aims to assess the efficacy of the ozonized gel GeliO3 (Bioemmei Srl, Vicenza, Italy) plus SRP (experimental treatment), with respect to SRP + chlorhexidine gel. Ten participants were treated with SRP + chlorhexidine gel (control sites) and with SRP + ozone gel (trial sites). After 1 (T1) and 3 months (T2) from baseline (T0), patients were revisited. At each time-point, the following indexes were assessed: probing pocket depth (PPD), clinical attachment level (CAL), gingival index (GI), plaque index (PI), and bleeding on probing (BoP). It has been assessed that the use of the ozonized gel in addition to SRP did not show significant differences if compared to conventional SRP + chlorhexidine. Chlorhexidine was found to be more effective than ozone in reducing CAL and GI at T2. Ozone deserves consideration for its wide applicability in several clinical fields. In this connection, we also glance at the latest research on ozone therapy.

RESUMEN

OBJECTIVES: The aim of the study is to histologically evaluate the effect of ozone therapy on orthodontic force induction in an animal model. MATERIALS AND METHODS: Twenty-four Wistar rats were divided into three groups (n = 8). A NiTi coil spring was installed from the maxillary first molar to the maxillary central incisor. G1 was control and G2/G3 received 1 mL of ozonated gas at concentrations of 10 and 60 µg/mL, in the buccal mucosa above the first molar roots. The animals were euthanized 3 and 5 days after the procedure. Histological sections were obtained, longitudinally of the first molar' long axis, in the mesiodistal direction. The number of osteoclasts, osteoblasts, blood vessels, polymorphonuclear and mononuclear cells, formation of osteoid tissue and hyaline areas, and root resorption were evaluated with light microscope, in tension and pressure sides. Intergroup comparisons were performed with Kruskal-Wallis, Dunn, and Chi-square tests. RESULTS: At 3-days pressure side, a greater number of osteoclasts was observed in ozone groups and greater number of blood vessels and polymorphonuclear cells were observed in G2. On the tension side, there was a significantly greater number of blood vessels, osteoblasts, and mononuclear cells in G2. At 5-days pressure side, there was a significantly greater number of osteoclasts in G2, blood vessels and osteoblasts in the ozone groups, and lesser number of polymorphonuclear cells in G3. CONCLUSION: Ozone therapy increased the number of osteoclasts on the pressure side and osteoblasts on tension side, in 10 µg/mL concentration, demonstrating histological parameters favorable to bone remodeling. The 60 µg/mL ozone concentration accelerated the periodontal ligament reorganization process.

RESUMEN

OBJECTIVES: Candida adherence to the denture base is an important cause of denture stomatitis in elderly and handicapped patients where effective patient- and physician-based disinfection methods are required. The purpose of this study was to investigate the in vivo effectiveness of chemical and physicochemical methods and their combinations against common oral Candida species on denture base acrylic resin. METHOD AND MATERIALS: Patients were divided into six groups according to disinfection methods. For chemical disinfection, chlorhexidine, sodium hypochlorite, and glutaraldehyde were used by the patients. Microwave and ozone therapy were applied by physicians for physicochemical disinfection. Fungal load count was performed. This procedure was repeated before applying any disinfection procedures, at 1 week and 1 month after the patient started to use the relevant chemical disinfectant and apply physicochemical methods. A multivariate analysis test was used to determine the change in fungal load over time and whether this change led to a difference among the groups (P < .05). RESULTS: The most frequently isolated Candida strain was Candida albicans. The change in fungal load over time was significantly different (P < .001). However, the difference between the groups did not show any significant difference in the paired comparison analyses of the chemical disinfection groups (P >.05). No Candida strains were detected in either physicochemical method at any of the control time points. CONCLUSIONS: The study concluded that chemical disinfectants used by patients were effective for but total eradication of Candida adhesion requires the use of additional ozone or microwave therapy.

RESUMEN

OBJECTIVE: To identify the best available approach to avoid initial caries lesions progression in primary teeth. MATERIALS AND METHODS: Search was performed in MEDLINE/Pubmed, Web of Science, Embase and CENTRAL databases until March 2021. Studies compared treatment options to avoid the initial caries lesion progression with at least 12 months of follow-up were included. Network meta-analyses were conducted considering the non-progression of caries lesions as an outcome. RESULTS: Potentially eligible studies were screened (n = 2820) and eleven were included. Six studies evaluated the use of fluoride varnish, resin infiltration, sealing, and toothbrushing/flossing on proximal initial caries lesions. When considering occlusal surfaces, only two studies evaluating the ozone gas, fluoride varnish, resin infiltration, and sealants were included. For buccal/lingual surfaces, three studies evaluating toothbrushing, CPP-ACP paste, fluoride varnish, and resin infiltration were included. For all types of surfaces, the resin infiltration showed the best probability to avoid the progression of initial caries lesions. CONCLUSION: The limited number of included studies, most with a high risk of bias and lack of hard outcomes, such as frank cavitation, makes it not feasible to recommend a specific management approach for initial caries lesion control in primary teeth with a high certainty of evidence. PROSPERO: #CRD42016037781.

RESUMEN

PURPOSE: To assess the effects of grade IV titanium ultrasonic tip instrumentation on different grade IV titanium implant surfaces and compare the decontamination of different implant surfaces using chlorhexidine, blue laser, or ozone. MATERIALS AND METHODS: Profilometry and energy-dispersive x-ray spectroscopy (EDS) analyses were performed on smooth, laser-micropatterned, and sandblasted grade IV titanium sample disks before (t0) and after (t1) ultrasonic instrumentation with an ultrasonic grade IV titanium tip. Samples were also incubated with a Streptococcus sanguinis culture. Each surface type was then treated with chlorhexidine, blue laser, or ozone (three test groups + control group). Scanning electron microscopy (SEM) images were taken after bacterial growth and after decontamination. RESULTS: After ultrasonic instrumentation, surface roughness (Ra) decreased on sandblasted and micropatterned surfaces, whereas it remained substantially unvaried on the smooth surface. SEM images revealed that the laser-micropatterned structure remained substantially unvaried after instrumentation. EDS revealed a minimal quantity of carbon and iron, found in the laser-treated and sandblasted group at t0. A minimal quantity of aluminum and oxygen was found on the sandblasted surface at t0 and t1. Ozone therapy achieved the highest decontaminating effect, regardless of implant surface topography. CONCLUSION: Among the alternative therapies to ultrasonic instrumentation with titanium tips, ozone appears to be effective regardless of the type of implant surface; it can be used for the decontamination treatment of implants without altering the surface structure.

RESUMEN

This study aims to assess ozonized mineral oil ointment application as an antiplaque therapy for dogs. Domestic healthy dogs received dental scaling and polishing under general anesthesia. Under standard feeding and homecare during 7 days, 20 dogs were randomly placed into 2 different groups for dental treatment. The control group (CG) was given a single placebo application and the ozone group (O3G) received daily ozonized ointment application. The average age (CG = 4.4; O3G = 5.7 years old), body weight (CG = 15.7; O3G = 15.3 kg) and the gingivitis index obtained on the first day (D0) allowed initial homogeneity between the groups. The dental plaque index, including clinical and computerized analysis on the seventh day, was obtained from the buccal aspect of specific dental locations. Both analyses revealed significant statistical association between daily application of ozone and antiplaque effect. There was no evidence of toxicity during the study. These results suggest that ozone therapy may be an efficient adjuvant to conventional periodontal treatment in decreasing initial dental plaque formation.

RESUMEN

The aim of this controlled randomized crossover study was to assess post-treatment pain and the need for root canal treatment after the use of a traditional caries removal method followed by restoration, or after an ozone method of more conservatively managing the deep caries and a restoration. 84 participants (42 males and 42 females, mean age ± SD = 23.9 ± 2.0 years) were randomly allocated to receive either a traditional (n = 42, 21 males and 21 females) or ozone (n = 42, 21 males and 21 females) method. The ozone method only differed from the traditional method by leaving the deep leathery caries on the pulpal floor and then treating this with 20 s of ozone from the healozone X4 (Curozone, Germany). All caries was removed in the traditional group. A conventional glass ionomer cement (Riva Self Cure High Viscosity, SDI, Australia) was placed followed by a bonded composite resin restoration (Filtek Z250 Universal Restorative, 3 M ESPE, USA) in each cavity. The visual analogue scale was used to assess pain scores before treatment and after 24 h. The participants were then followed up for 2 years to assess the need for root canal treatment. Statistical significance levels were set at α ≤ .05. Both groups were associated with significant reduction of pain scores 24 h after treatment (p < .0001). The ozone treatment was associated with less pain 24 h after treatment (p < .0001) and less need for root canal treatment (p = .014), after 2 years follow up, than the conventional treatment. In conclusion, treatment of symptomatic, deep carious lesions by ozone following partial removal of caries was accompanied with less pain and occurrence of RCT after treatment compared to traditional complete caries removal.

RESUMEN

BACKGROUND: Dental implant surgery despite its growing popularity poses several challenges like include tissue inflammation, pain discomfort and tissue injury. OBJECTIVE: To evaluate the effect of ozone therapy on inflammation, pain and wound healing after implant surgery. METHODS: A clinical study was conducted on 60 systematically healthy patients- 30 patients treated with ozone (Experimental group) and 30 patients without ozone treatment (control group). In the control group osteotomy procedure was performed with saline irrigation and in the experimental group irrigation was done with ozonated water at 25 µg/mL concentration, along with ozone gas. Clinical assessment was done by evaluating C-reactive Protein (CRP) for inflammation, pain using Visual Analogue Scale (VAS) score and tissue wound healing using wound healing index. Side effects, if any, were noted. RESULTS: Postoperative increment in CRP levels was 0.10 and 0.63 mg/dl in Experimental and control groups respectively (p < 0.001). At 24-hr, 48-hr and 7 day post-operative intervals mean VAS scores for pain were significantly higher in Control group as compared to that in Experimental Group (p < 0.001). At day 7, mean VAS scores for pain were 3.50 ± 0.63 and 37.70 ± 4.17 in Experimental and Control groups respectively (p < 0.001). Mean tissue healing indices were significantly higher on Day 7 and Day 14 in Experimental Group (4.23 ± 0.43 and 4.97 ± 0.18) as compared to that in control group (3.07 ± 0.45 and 4.03 ± 0.18) (p < 0.001). No potential side effects were noted in either of two groups. CONCLUSION: Ozone therapy accelerated the tissue wound healing, minimized tissue inflammation and decreased pain.

RESUMEN

Prions are infectious agents causing prion diseases, which include Creutzfeldt-Jakob disease (CJD) in humans. Several cases have been reported to be transmitted through medical instruments that were used for preclinical CJD patients, raising public health concerns on iatrogenic transmissions of the disease. Since preclinical CJD patients are currently difficult to identify, medical instruments need to be adequately sterilized so as not to transmit the disease. In this study, we investigated the sterilizing activity of two oxidizing agents, ozone gas and vaporized hydrogen peroxide, against prions fixed on stainless steel wires using a mouse bioassay. Mice intracerebrally implanted with prion-contaminated stainless steel wires treated with ozone gas or vaporized hydrogen peroxide developed prion disease later than those implanted with control prion-contaminated stainless steel wires, indicating that ozone gas and vaporized hydrogen peroxide could reduce prion infectivity on wires. Incubation times were further elongated in mice implanted with prion-contaminated stainless steel wires treated with ozone gas-mixed vaporized hydrogen peroxide, indicating that ozone gas mixed with vaporized hydrogen peroxide reduces prions on these wires more potently than ozone gas or vaporized hydrogen peroxide. These results suggest that ozone gas mixed with vaporized hydrogen peroxide might be more useful for prion sterilization than ozone gas or vaporized hydrogen peroxide alone.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the preventive effect of ozonated oil on the development of MRONJ-like lesions at tooth extraction sites in rats submitted to zoledronic acid treatment. MATERIALS AND METHODS: Twelve rats were divided into two groups. Each rat received an injection of zoledronic acid solution once a week for 5 weeks before having its upper first molar extracted. In group 1, the clotted socket was maintained, while in the group 2, the socket was treated with ozonated oil for 10 min/day during 3 days. After euthanasia, block resection was performed for histological analysis. Necrotic bone was defined as the area of the bone with empty osteocyte lacunae and vital bone as the area with osteocyte-occupied lacunae. RESULTS: There was no statistically significant difference between the groups in the average area of vital bone (p = 0.2248) and the average area of necrotic bone (p = 0.1208). However, the average area of vital bone in group 1 was smaller (24.1 ± 2.9 cells/cm2) than in group 2 (26.8 ± 4.2 cells/cm2), and the average area of necrotic bone in group 1 was higher (7.0 ± 2.5 cells/cm2) than in group 2 (4.0 ± 1.1 cells/cm2), indicating that ozonated oil may reduce the development of osteonecrosis. CONCLUSIONS: Our findings suggest that ozonated oil might prevent MRONJ-like lesions at tooth extraction sites in rats submitted to a disease induction protocol. Further research should be conducted to confirm this hypothesis. CLINICAL RELEVANCE: MRONJ has been reported as a complication of surgical dental procedures, and there are currently no predictable preventive therapies.

La variante de tratamiento de curación con aceite ozonizado e irradiación con láser fue la más implementada. Los valores de lesiones resueltas y mejoradas a los 90 días fueron satisfactorios.


ABSTRACT Introduction: Medication-related osteonecrosis of the jaws is an affection associated with the treatment with bisphosphonates, antiresorptive agents or antiangiogenic medications. Objective: To perform a clinical and therapeutic characterization of patients with the diagnosis of medication-related osteonecrosis of the jaws. Material and Method: A case series of a total of 19 patients with the diagnosis of medication-related osteonecrosis of the jaws was carried out in the Department of Dental and Maxillofacial Surgery of ¨Raúl González Sánchez¨ Dental School of Havana from January 2018 to January 2019. The severity and risk factors were identified and the treatment including the healing with ozone oil and the application of infrared laser was standardized. The patients were evaluated in the 90 days after treatment. The operationalization of variables included: sex, type of medications, ways and time of administration, localization, and evaluation of treatment. Results: The average age of patients was 69±8,5 years and 52,63% of them were male. Zolendronate was the most associated agent in 78,95% of cases. Periodontal disease was the most identified local factor (57, 89%). The posterolateral area of the mandible and stage 2 disease evolution predominated in 63,16% and 52, 63% of lesions, respectively. Also 78, 94% of cases had a satisfactory evolution in the 90 days after treatment. Conclusions: The administration of intravenous bisphosphonates, particularly Zolendronate, was the main cause of osteonecrosis. These lesions were mainly located in the posterior lateral area of the mandible and presented stage 2 disease evolution. Healing with ozone oil and application of infrared laser was the most implemented alternative treatment. The values of resolved and improved lesions were satisfactory in the 90 days after treatment.

RESUMEN

OBJECTIVE: To compare the remineralization potential and caries preventive efficacy of CPP-ACP/bioactive glass/xylitol/ozone and topical fluoride (TF) combined therapy versus TF mono-therapy. MATERIAL AND METHODS: Embase, PubMed, Scopus, Web of Science and Cochrane databases were searched. 4457 records were screened and 26 trials were included. Data from 16 trials was pooled using Review Manager 5.4. Level of significance was p < .05. The certainty of the evidence was evaluated using GRADE. RESULTS: Pooled analysis of two trials for white spot lesions (WSLs) regression (SMD -0.6, 95% CI: [-1.07 to -0.14], p = .01) and three trials for post-intervention DIAGNOdent values (SMD -1.24, 95% CI: [-1.96 to -0.52], p = .0007) significantly favoured CPP-ACP-TF combined therapy over TF mono-therapy. The sub-group analysis for caries increment (SMD -0.14, 95% CI: [-0.21 to -0.07], p < .0001) and the post intervention S mutans count (SMD -0.42, 95% CI: [-0.62 to -0.23], p < .0001) significantly favours 'xylitol-TF' and 'CPP-ACP-TF' combined therapy respectively. The high/unclear risk of bias, imprecision and indirectness of the included trials presented a low certainty of evidence. CONCLUSION: CPP-ACP-TF exhibits superiority over TF monotherapy in remineralizing existing lesions and demonstrates better antibacterial effect, whereas it is not more effective for preventing caries incidence. However, Xylitol exerts an added benefit over fluoride alone in preventing caries increment. The low-certainty evidence highlights the need for more good quality trials.

RESUMEN

Osteoradionecrosis is a relatively rare but potentially morbid and costly complication of radiation therapy for head and neck cancer. Multidisciplinary diagnosis and treatment are essential. Despite evidence guiding individual aspects of care for osteoradionecrosis, there is a lack of broad consensus on the overall diagnosis and management of this condition. This study comprehensively reviews the literature, with a focus on the past 10 years, to guide evaluation and treatment.
