RESUMEN

AIM AND OBJECTIVE: This study aimed to evaluate the effect of ozonated water used as an irrigant and dentin-cleaning solution on the bond strength of fiberglass pins in vitro, comparing it with the commonly used solutions. MATERIAL AND METHODS: Seventy-seven bovine roots were randomly divided into seven groups according to the irrigant and dentin-cleaning solution to be used: HP/HP, 2.5% sodium hypochlorite; DA/DA, distilled water; CHX/CHX, 2% chlorhexidine; OA/OA, 4 ppm ozonated water; HP/DA; HP/CHX; and HP/OA. In each group, the root canals were endodontically prepared by using the corresponding irrigant and stored in DA; after 7 days, they were cleared and cleaned with the corresponding cleaning solution. The fiberglass pins were cemented by using self-adhesive cement. After 7 days, the roots were sectioned (six discs each) and submitted to the push-out test. The type of fracture was analyzed with a 4.5x stereoscopic magnifying glass. The data were analyzed by the analysis of variance and the Tukey test at a 5% significance level. RESULTS: The OA/OA (11.67), HP/HP (11.21), and HP/OA (9.71) groups showed the highest mean push-out bond strength (MPa) in the cervical third. The same trend was maintained in the middle and apical thirds. CONCLUSION: Ozonated water and 2.5% sodium hypochlorite are the most relevant solutions for root dentin treatment. CLINICAL RELEVANCE: Teeth treated with ozonated water, sodium hypochlorite, and a combination of the two showed greater bond strength than those treated with other solutions.

RESUMEN

Background: There is an increased prevalence of oral ailments such as dental caries, gingivitis, and periodontitis when orthodontic therapy is administered. Poor oral hygiene in conjunction with the placement of fixed orthodontic appliances is considered a significant factor in raising accumulation of bacterial plaque and its associated inflammatory response. Aim: The present study aimed to evaluate and compare laser therapy with subgingival irrigation using ozonated water on gingivitis in patients undergoing fixed orthodontic treatment and to ascertain the presence of the inflammatory marker monocyte chemoattractant protein (MCP-1) in gingival crevicular fluid (GCF). Methods: This study was a double-blind clinical study in which a split-mouth design was applied in 30 subjects for 28 days that received fixed orthodontic therapy. In each subject, the upper right quadrant (control side) was irrigated with 0.01 mg/L ozonated water and the upper left quadrant (experimental side) was irradiated with a diode laser on day 0 (baseline) and day 7. The patients were recalled on days 7, 14, and 28 and clinical parameters were recorded at each visit. Biochemical evaluation of gingival inflammation with MCP-1 levels in GCF was obtained at the baseline (day 0) and on day 28. Results: A statistically significant (p < 0.05) reduction of all clinical parameters and MCP-1 activity in GCF was observed on both sides. Low-level laser irradiation showed a significant reduction of clinical parameters and MCP-1 activity compared to subgingival ozone irrigation. Conclusions: Laser therapy can be considered a more effective method than subgingival ozone irrigation in patients undergoing fixed orthodontic treatment as it showed a consistent improvement in gingival inflammation. Relevance for patients: Fixed orthodontic appliances make oral hygiene maintenance difficult and results in gingivitis. Adjunctive oral hygiene procedures such as subgingival irrigation with ozonated water or laser irradiation are beneficial. The data from this study suggest that irrigation with ozonated water or laser irradiation reduces gingival inflammation, with laser therapy being more effective.

RESUMEN

AIM: To evaluate the shear bond strength (SBS) of caries effected dentin (CAD) bonded to resin-modified glass ionomer cement (RMGIC) after being disinfected with different methods their effect on microleakage scores. MATERIAL AND METHODS: Based on criteria of ICDAS seventy-five teeth were selected and disinfected. All samples were grounded and a cavity prepared followed by random allocation of samples into different disinfection groups i.e., methylene blue photosensitizer (MBP), Silver diamine fluoride (SDF), Ozone (O3); curcumin photosensitizer (CP) and chlorhexidine (CHX) (n = 15). All samples were restored with resin modified glass ionomer (RMGIC) incrementally. Ten specimens from each group were placed in universal testing machine (UTM) to calculate bond failure and failure type. Five samples from each group were evaluated for microleakage scores. SBS and microleakage scores was examined using analysis of variance (ANOVA) with a Post-hoc test. For all tests p-value, less than 0.5 was considered statistically significant. RESULTS: The highest SBS was observed in CAD disinfected with CP bonded to RMGIC (16.42 ± 1.10 MPa). Similarly, the lowest bond values were demonstrated by CAD disinfected with MBP (9.21 ± 0.22 MPa) bonded to RMGIC respectively. CAD disinfected with CHX (Control) bonded to RMGIC demonstrated the lowest microleakage scores and showed a significant difference compared to other experimental groups (p< 0.05). CONCLUSION: Curcumin along with O3 has the potential to be used as a disinfectant in CAD as it improves SBS to RMGIC. CHX demonstrates low microleakage scores with decrease of bond integrity.

RESUMEN

This study investigated the bleaching effectiveness and the physicochemical effects on enamel of violet light and ozone, associate or not to hydrogen peroxide, compared to 35%-hydrogen peroxide. Enamel-dentin blocks from human molars were randomly allocated to receive one of the following bleaching protocols (n=15): (HP) 35%-hydrogen peroxide, (VL) violet light, (OZ) ozone, the association between hydrogen peroxide with ozone (OZ+HP) or violet light (VL+HP). All protocols were performed in two sessions with a 48h interval. Color (spectrophotometer) and mineral composition (Raman spectroscopy) were measured before and after the bleaching. Color changes were calculated by ΔEab, ΔE00, and whitening index (WI). The surface roughness was measured with an atomic force microscope. Data were analyzed by One-way or Two-way repeated measure ANOVA followed by the Tukey's test (α = 0.05). The lowest color change values (either measured by WI, ΔEab, or ΔE00) were observed for VL and OZ used with no HP. Violet light associate with HP was unable to improve the color changes observed for the peroxide alone, in combination with OZ and HP, the highest color changes were verified. Regardless of bleaching protocol, the bleached enamel presented higher contents of PO4 and CO3 -2 than those observed at baseline. All bleaching protocols resulted in similar enamel surface roughness. Both the VL and the OZ caused reduced effects on the enamel color change when used alone. The ozone therapy improved the bleaching effect in the group that received the association of HP.

RESUMEN

Objective: Photobiomodulation (PBM) using diode laser is regarded an effective modality for the repair of tissues and control of pain. Ozone, owing to its biocompatibility, healing, and antimicrobial properties, is used in dentistry as well. This study was carried to clinically compare and evaluate the healing of gingival depigmented wounds using ozonated oil and PBM. Materials and Methods: A laser depigmentation procedure was conducted on seven patients exhibiting bilateral upper and lower gingival melanin hyperpigmentation, followed by the application of ozonated oil (Group 1) and laser PBM (Group 2). The clinical parameters are taken namely Visual Analog Scale and Healing Index (HI), were evaluated on the 3rd, 7th, and 15th day. Results: Statistical analysis showed better HI in Group I as compared to Group II on the 3rd day, but it was comparable in both groups on the 7th and 15th day. Conclusion: The application of ozonated oil was found to be more efficacious in promoting the initial healing of wound in comparison to PBM. Both ozonated oil and PBM also showed the same capabilities in reduction of the postoperative pain.

RESUMEN

AIM: To assess the efficacy of photosensitizers (CP, riboflavin) and gaseous ozone in comparison to the conventional radicular dentin disinfectant (NaOCl) on push-out bond strength (PBS) of PFRC post cemented to radicular dentin MATERIAL AND METHOD: Human single-rooted teeth were collected, steriled implanted in polyvinyl pipes up to a cement-o-enamel junction and de coronated. Cleaning and shaping of the canal were performed using the crown down technique followed by obturation of the canal space. Canal space was prepared using peso reamers and samples were divided into four groups based on types of canal disinfectant protocols. Group 1: Riboflavin+ 17%EDTA; group 2: Curcumin Photosensitizer + 17% EDTA; group 3: Gaseous Ozone disinfection (O3) +17% EDTA and group 4 control 2.5% NaOCl +17% EDTA. Within the canal space, fiber post was cemented and cured, and thermocycled. PBS was evaluated using a Universal testing machine (UTM) and failure modes using a stereomicroscope at 40x magnification. One-way analysis of variance (ANOVA) was used to determine the mean and standard deviation of push-out bond strength (PBS). The Tukey multiple comparison tests (p = 0.05) was used to compare the means of PBS RESULTS: The highest PBS was displayed in group 2 CP+ 17% EDTA at all three root levels, coronal (8.81±0.61), middle (7.77±0.55), and apical (5.25±0.61). The lowest PBS was revealed in group 4, disinfected with 2.5% NaOCl +17% EDTA (control) at coronal (6.12±0.54), middle (5.46±0.84), and apical (3.00±1.88) levels. The most prevailed fracture mode was an adhesive failure (cement-dentin interface). CONCLUSION: Radicular dentin disinfected with PDT using CP, riboflavin, and O3 displayed similar PBS at all root segments. NaOCl is a convenient, traditional, and commonly used disinfectant, and it's effects on PBS is still controversial.

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

BACKGROUND: The aim of this study was to compare the push-out bond strength of fiber posts by using two different resin cement after the treatments of post space with photodynamic therapy, gaseous ozone and conventional disinfection solution. METHODS: The root canal treatments of one hundred maxillary incisors were performed. The roots were randomly distributed into 5 groups (n = 20). NaOCl of 2.5% + EDTA of 17% in group 1, CHX of 2% in group 2, toluidine blue + diode laser as the photodynamic therapy (PDT) in group 3 and ozone in group 4 were applied to the post spaces. Group 5 was washed with distilled water as control group. Each group was divided into two subgroups according to the adhesive types and the posts were bonded by using RelyX and LinkForce. The bond strength was calculated using the push-out test method. Resin tag formations were photographed with SEM. The push-out bond strength was analyzed by ANOVA and Tukey tests (p = .05). RESULTS: The PDT group, which showed the highest PBS among the groups bonded with LinkForce at all levels, was significantly higher than Ozone and DW groups (p<.05). NaOCl and ozone treatments provided the highest PBS among the groups bonded with RelyX for all levels and this difference was significant according to the DW group (p < .05). CONCLUSION: Post space treatments improved the bond strength of the fiber post ​​in both types of resin cement.

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

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

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

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

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: 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

BACKGROUND: Periodontal infection may contribute to poor glycemic control and systemic inflammation in diabetic patients. The aim of the present study is to evaluate the efficacy of non-surgical periodontal treatment in diabetic patients by measuring oxidative stress outcomes. METHODS: Sixty diabetic patients with periodontitis were enrolled, treated with scaling and full-mouth disinfection, and randomly prescribed chlorhexidine mouthwash, antioxidant mouthwash, or ozone therapy. Reactive oxygen metabolites (ROMs), periodontal parameters, and glycated hemoglobin were measured at baseline and then at 1, 3, and 6 months after. RESULTS: At baseline, all patients presented with pathologic levels of plasmatic ROM (388 ± 21.36 U CARR), higher than the normal population. Probing depth, plaque index, and bleeding on probing values showed significant clinical improvements after treatment, accompanied by significant reductions of plasma ROM levels (p < 0.05). At the 6-month evaluation, the mean ROM relapsed to 332 ± 31.76 U CARR. Glycated hemoglobin decreased significantly (∆ = -0.52 units) after treatment. Both the test groups showed longer-lasting improvements of periodontal parameters. CONCLUSION: In diabetic patients, periodontal treatment was effective at reducing plasma ROM, which is an indicator of systemic oxidative stress and inflammation. The treatment of periodontal infection might facilitate glycemic control and decrease systemic inflammation.

RESUMEN

This systematic review assessed the effectiveness of ozone (O3) in the color change of in-office tooth bleaching in vital teeth (TB) and the sensitivity control. Only randomized controlled clinical trials were included. Seven databases were used as primary search sources, and three additional sources were searched to capture the "grey literature" partially. The JBI tool was used to assess the risk of bias. TB was assessed using the ΔELab color change metric comparing tooth color pre- and post-bleaching. We meta-analyzed the ΔELab estimates per method and calculated the absolute standardized mean difference using random-effect models. The GRADE approach assessed the certainty of the evidence. The ΔELab estimates ranged from 1.28 when the O3 was used alone to 6.93 when combined with hydrogen peroxide (HP). Two studies compared O3 and HP alone, but their TB was similar (SMD = - 0.02; 95%CI: - 0.54; 0.49). The bleaching effectiveness for the combination of O3 + HP compared to HP was similar (SMD = 0.38; 95%CI: - 0.04; 0.81). Thus, based on the available literature, our findings suggest that O3 is not superior to the conventional technique using HP on the change of tooth color. The O3 did not present sensitivity when used alone. When O3 was used in combination with HP, patients reported hypersensitivity only when O3 was applied before HP, i.e., no sensitivity was perceived when O3 was applied after HP.

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

RESUMEN Introducción: el ozono por su amplia gama de propiedades es útil para tratar afecciones bucales como la gingivitis crónica. Objetivo: demostrar efectividad de la ozonoterapia en el tratamiento de la gingivitis crónica en adolescentes en el Policlínico "Pedro Borrás Astorga", del municipio Pinar del Río, en el período comprendido entre enero y septiembre de 2019. Métodos: se realizó un estudio observacional, analítico, longitudinal, de casos y control. La muestra quedó conformada por 50 pacientes seleccionados por el método no probabilístico intencionado, teniendo en cuenta los criterios de inclusión y exclusión. Para un mejor estudio se formaron dos grupos, uno de estudio tratado con oleozón y otro de control tratado con propóleos al 5 %, con 25 pacientes cada uno. Se utilizaron métodos teóricos, empíricos, y se aplicó la prueba de Chi cuadrado con un nivel de significación de p=0.05. Resultados: se demostró la efectividad de la aplicación del oleozón en la muestra seleccionada al presentar una evaluación terapéutica de los pacientes más favorable con respecto a los tratados con propóleos al 5%, alcanzando la mayor cantidad de pacientes curados y con éxito en el tratamiento de la gingivitis crónica, la que fue más presentada por adolescentes masculinos de 13 años, prevaleció en su forma moderada, y la higiene bucal deficiente fue el factor de riesgo de mayor incidencia en su aparición. Conclusiones: la ozonoterapia resultó ser un tratamiento efectivo para la gingivitis crónica en los adolescentes estudiados.


ABSTRACT Introduction: the ozone due to its ample range of properties is useful to treat oral diseases as chronic gingivitis. Objective: to demonstrate the effectiveness of ozone-therapy in the treatment of chronic gingivitis in adolescents at Pedro Borras Astorga Polyclinic, Pinar del Rio municipality, during the period between January and September 2019. Methods: an observational, analytical, longitudinal study of case and control. The sample comprised 50 patients chosen by intentional non-probabilistic method, considering the criteria of inclusion and exclusion. To carry out a better study two groups were included, a study group treated with oil-ozone and a control one treated with propolis at 5 %, with 25 patients each of the group. Theoretical and empirical methods were applied, and the chi-squared test with a significance level of p=0.05. Results: the effectiveness of the application of oil-ozone was demonstrated in the sample chosen when presenting a more favorable therapeutic evaluation of the patients, respect to those treated with propolis at 5 %, reaching the greatest quantity of cured patients and with success in the treatment of chronic gingivitis, which was more frequent in male adolescents (13 years old), its moderate type prevailed, a deficient oral hygiene was the risk factor of highest incidence in its onset. Conclusions: the ozone-therapy resulted in an effective treatment for chronic gingivitis in the studied adolescents.

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.
