Ozone therapy improves early stages of osseointegration in ovariectomized rats.

OBJECTIVE: the aim of this study was to analyze the influence of ozone therapy (OZN) on peri-implant bone repair in critical bones by installing osseointegrated implants in the tibia of ovariectomized rats. METHODOLOGY: ovariectomy was performed on 30 Wistar rats, aged six months (Rattus novergicus), and, after 90 days, osseointegrated implants were installed in each tibial metaphysis. The study groups were divided into the animals that received intraperitoneal ozone at a concentration of 700 mcg/kg - OZ Group (n=15) - and a control group that received an intraperitoneal saline solution and, for this reason, was named the SAL group (n=15). The applications for both groups occurred during the immediate post-operative period on the 2nd, 4th, 6th, 8th, 10th, and 12th day post-surgery. At various stages (14, 42, and 60 days), the animals were euthanized, and tests were performed on their tibiae. These tests include histomorphometric and immunohistochemical analyses, computerized microtomography, sampling in light-cured resin for calcified sections, and confocal microscopy. The obtained data were then analyzed using One-way ANOVA and the Shapiro-Wilk, Kruskal-Wallis, and student t-tests (P<0.05). RESULTS: our findings indicate that the OZ group (3.26±0.20 mm) showed better cellular organization and bone neoformation at 14 days (SAL group, 0.90±1.42 mm) (P=0.001). Immunohistochemistry revealed that osteocalcin labeling was moderate in the OZ group and mild in the SAL group at 14 and 42 days post-surgery. The data from the analysis of calcified tissues (microtomography, histometric, and bone dynamism analysis) at 60 days showed no statistically significant differences between the groups (P=0.32). CONCLUSION: it was concluded that ozone therapy anticipated the initial phases of the peri-implant bone repair process.

Predictability of single versus double-barrel vascularized fibula flaps and dental implants in mandibular reconstructions: A systematic review and meta-analysis of prospective studies.

STATEMENT OF PROBLEM: Patients with vascularized bone flaps from the fibula have reduced bone height, in which case a higher prosthetic abutment is needed for their implant-supported prosthesis. Although the double-flap technique seems promising, systematic reviews and meta-analyses of prospective studies are lacking. PURPOSE: The purpose of this systematic review and meta-analysis was to evaluate the grafted areas of single barrel fibular flaps (SBFF) and double-barrel fibular flaps (DBFF) by considering failure rates, dental implant complications, and bone union at the osteotomy sites. MATERIAL AND METHODS: A systematic review and meta-analysis was performed in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, population, intervention, control, and outcomes (PICO) question, and the National Health and Medical Research Council scales. The event rate of complications and failures was calculated with a confidence interval (CI) of 95%. RESULTS: A total of 13 prospective studies with 441 participants and 330 graft sites were identified. A total of 235 participants had SBFF with 445 implants, and 95 had DBFF with 164 implants. The overall combined graft failure rates were 4.2% for SBFF and 3.2% for DBFF. The complication rate was 10% for SBFF and 1.9% for DBFF. Implant failure was at 4.7% in the SBFF group and 3.4% in the DBFF group. CONCLUSIONS: Complication rates and implant failures were similar for SBFF and DBFF. Therefore, for long-term oral rehabilitation, both SBFF and DBFF are suitable procedures for mandibular reconstruction.

Comparison of Manual (2D) and Digital (3D) Methods in the Assessment of Simulated Facial Edema.

BACKGROUND: An edema assessment following dental surgeries is essential to improving the dental surgeon's technique and, consequentially, patient comfort. PURPOSE: Two-dimensional (2D) methods are limited in analyzing 3-dimensional (3D) surfaces. Currently, 3D methods are used to investigate postoperative swelling. However, there are no studies that directly compare 2D and 3D methods. The goal of this study is to directly compare 2D and 3D methods used in the assessment of postoperative edema. STUDY DESIGN AND SAMPLE: The investigators implemented a prospective, cross-sectional study with each subject serving as its own control. The sample was composed of dental student volunteers without facial deformities. PREDICTOR VARIABLE: The predictor variable is the method used to measure edema. After simulating edema, manual (2D) and digital (3D) techniques were used to measure edema. The manual method used direct facial perimeter measurements. The two digital methods were photogrammetry using a smartphone (iPhone 11, Apple Inc, Cupertino, California), and facial scanning with a smartphone application (Bellus3D FaceApp, Bellus3D Inc, Campbell, California) [3D measurements] MAIN OUTCOME VARIABLE: The coefficient of variation (CV) (CV = standard deviation /mean) was used to assess homogeneity of edema measurements. ANALYSIS: The Shapiro-Wilk and equal variance tests were applied to assess data homogeneity. Next, one-way analysis of variance was performed, followed by a correlation analysis. Finally, the data were submitted to Tukey's test. The statistical significance threshold was set at 5% (P < .05). RESULTS: The sample was composed of 20 subjects aged 18-38 years. The CV showed higher values using the manual (2D) method (47%; 4.88% ± 2.99), compared with the photogrammetry method (18%; 8.55 mm ± 1.52) and the smartphone application (21%; 8.97 mm ± 1.93). A statistically significant difference was observed between the manual method values and those of the other two groups (P < .001). There was no difference between the facial scanning and photogrammetry groups (3D methods) (P = .778) CONCLUSION AND RELEVANCE: Both digital measuring methods (3D) demonstrated greater homogeneity than the manual method in analyzing facial distortions caused by the same swelling simulation. Therefore, it can be affirmed that digital methods may be more reliable that manual methods for assessing facial edema.

Single intraoperative infrared laser optimized bone repair in rat femoral osteotomies with experimentally induced osteoporosis.

This study aimed to evaluate the effect of infrared laser (IRL) on bone repair in ovariectomized rats subjected to femoral osteotomies. Of 32 rats, half underwent bilateral ovariectomy (OVX) and the other half underwent sham ovariectomy (SHAM). A period of 3 months was defined to observe the presence of osteoporosis. The rats were subjected to osteotomies in the femurs and then fixed with a miniplate and 1.5-mm system screws. Thereafter, half of the rats from both SHAM and OVX groups were not irradiated, and the other half were irradiated by IRL using the following parameters: wavelength, 808 nm; power, 100 mW; 60 s for each point; 6 J/point; and a total of 5 points of bone gap. All animals were euthanized 60 days after surgery. The femur gap was scanned using micro-computed tomography (micro-CT). The samples were then examined under a confocal laser microscope to determine the amounts of calcein and alizarin red. The slides were stained with alizarin red and Stevenel's blue for histometric analysis. In the micro-CT analysis, the OVX groups had the lowest bone volume (P < 0.05). When the laser was applied to the OVX groups, bone turnover increased (P < 0.05). New bone formation (NBF) was comparable between SHAM and OVX/IR (P > 0.05) groups; however, it was less in the OVX groups (P < 0.05). In conclusion, the results encourage the use of IRL intraoperatively as it optimizes bone repair, mainly in animals with low bone mineral density.

Evaluation of Two Beta-Tricalcium Phosphates with Different Particle Dimensions in Human Maxillary Sinus Floor Elevation: A Prospective, Randomized Clinical Trial.

This study aimed to compare two beta-tricalcium phosphates with different particle sizes in human maxillary sinuses lifting. The immunolabeling of cells for RUNX2 and VEGF were performed to evaluate the osteoblast precursor cells and the vascular formation after 6 months of bone repair. Ten maxillary sinuses were grafted with autogenous bone graft (Group 1), 10 were grafted with ChronOs® (Group 2), and 10 were grafted with BETA-TCP® (Group 3). After 6 months of bone healing, biopsies were obtained to assess the new bone formed by histomorphometric and immunohistochemical evaluation for RUNX2 and VEGF. The mean bone formation for Group 1 was 51.4 ± 17.4%. Group 2 presented 45.5 ± 9.9%, and Group 3 conferred 35.4 ± 8.0% of new bone formation. The RUNX2 offered low for Groups 1 and 2 with high cellular activity for osteoblast in Group 3. The VEGF immunolabeling was moderate for Groups 1 and 2 and intense for Group 3. In conclusion, it was possible to show that the bone substitutes evaluated in the present study presented suitable outcomes for bone regeneration, being an alternative for the autogenous bone graft in maxillary sinus bone height reconstruction.

Is an anodizing coating associated to the photobiomodulation able to optimize bone healing in ovariectomized animal model?

This in vivo study investigated whether the bioactivity of anodizing coating, produced by plasma electrolytic oxidation (PEO), on mini-plate in femur fracture could be improved with the association of photobiomodulation (PBM) therapy. From the 20 ovariectomized Wistar female rats, 8 were used for model characterization, and the remaining 12 were divided into four groups according to the use of PBM therapy by diode laser (808 nm; power: 100 mW; energy: 6.0 J; energy density: 212 J/cm2; power density: 3.5 W/cm2) and the type of mini-plate surface (commercially pure titanium mini-plate -cpTi- and PEO-treated mini-plate) as follow: cpTi; PEO; cpTi/PBM; and PEO/PBM. After 60 days of surgery, fracture healing underwent microstructural, bone turnover, histometric, and histologic adjacent muscle analysis. Animals of groups with PEO and PBM showed greater fracture healing than cpTi control group under histometric and microstructural analysis (P < 0.05); however, bone turnover was just improved in PBM's groups (P < 0.05). there was no difference between cpTi and PEO without PBM (P > 0.05). Adjacent muscle analysis showed no metallic particles or muscle alterations in all groups. PEO and PBM are effective strategies for bone repair in fractures, however their association does not provide additional advantages.

Three-dimensional volumetric changes of 5 different bone grafts in human maxillary sinuses reconstruction: a randomized clinical study.

PURPOSE: This study aimed to compare the three-dimensional volumetric changes of human maxillary sinuses after reconstruction using 5 different bone grafts. PATIENTS AND METHODS: Patients underwent unilateral maxillary sinus bone height reconstruction using 5 bone substitutes allocated in different groups as follows: group 1 was grafted with autogenous bone graft alone; group 2 with beta-tricalcium phosphate (ß-TCP); group 3 with ß-TCP + autogenous bone graft 1:1; group 4 with bioactive glass; and group 5 with bioactive glass + autogenous bone graft 1:1. The patients were submitted to cone beam computed tomography in two periods: 15 days after the surgical procedure (T1) and after 6 months (T2). The results were evaluated as the formula T2-T1 expressing the three-volumetric changes of the biomaterials in elapsed time. RESULTS: The resorption rate of autogenous bone graft was -630.699 ± 300.9 mm3; in the ß-TCP group, it was -315.772 ± 125.6 mm3; in the group with ß-TCP + autogenous bone graft 1:1, it was -336.205 ± 195.7 mm3; and in groups with bioactive glass and with the addition of autogenous bone graft 1:1, it was -428.878 ± 311.6 mm3 and -576.917 ± 471.6 mm3, respectively, without statistical difference (p = 0.167). Pearson's correlated test revealed a strong correlation as well as a progressive resorption of the grafts during bone healing. CONCLUSION: The similar outcomes for the three-dimensional volumetric changes using the bone substitutes evaluated after 6 months of bone healing suggest that all these grafts can be performed to maxillary sinus reconstruction.

Management of Unicistic Ameloblastoma in a Young Patient: Reducing Social Consequences.

ABSTRACT: Ameloblastoma is an odontogenic tumor of significant clinical relevance, aggressive and locally invasive. Although the posterior region of the mandible is more frequently affected, lesions observed in the maxilla should receive special attention due to the risk of expansion to the nasal, paranasal and orbital structures. This report shows a successful case of a maxillary ameloblastoma treated by combining therapies in a young patient. The treatment strategy adopted to reduce and redefine the lesion dimensions enabled enucleation in a safe way, without destruction of adjacent noble structures. It also allowed complementary approach with peripheral ostectomy and sclerosing agent, efficiently, without evidence of recurrence or complications after 2 years.

Avaliação do reparo ósseo com Bio-Oss® associado ao raloxifeno em levantamento de seio maxilar de coelhos / Evaluation of bone repair with Bio-Oss® associated with raloxifene in rabbit maxillary sinus lifting

O objetivo deste estudo foi analisar o potencial do Bio-oss® otimizado pelo processamento ultrassônico e associação com o raloxifeno no reparo ósseo em aumento de seio maxilar de coelhos. A associação dos materiais pesquisados foi realizada pelo processamento ultrassônico com 80% de Bio-oss e 20% de Raloxifeno. Para tanto, 8 coelhos (Oryctolagus cunilicus), machos, 6 meses de idade foram submetidos ao levantamento de membrana do seio maxilar bilateralmente, em seguida os seios maxilares foram preenchidos pelos biomateriais, de acordo com o grupo experimetal, sendo 4 animais (8 seios) por grupo: grupo 1 (BS) foi realizada a aplicação do Bio-oss submetido ao processamento ultrassônico sem raloxifeno, nos dois seios. O grupo 2 (BR) foi realizada a aplicação do Bio-oss com processamento ultrassônico juntamente ao raloxifeno, nos dois seios. Foi realizada eutanásia de 2 animais de cada grupo após 2 semanas da enxertia, para análise histométrica de osso neoformado, tecido conjuntivo e material remanescente, e para as reações de imunoistoquímica através do anticorpo primário contra Runx2. Já com 6 semanas, os outros 2 animais de cada grupo foram submetidos a eutanásia para avaliação de parâmetros histométricos (HE) e imunohistoquímicos para OCN, OPG, RANKK-L e TRAP. Os resultados obtidos mostraram superioridade para o grupo BS, que apresentou mais organização tecidual no período de 14 dias, além de maior quantidade de tecido ósseo neoformado aos 14 e 42 dias (p< 0,05). A avaliação imunoistoquímica revelou similaridade entre os escores para ambos os grupos, independente do tempo e proteína analisada. Conclui-se que a adição do raloxifeno, pelo processamento ultrassônico, aumentou reduzindo a quantidade de osso neoformado(AU)

The aim of this study was to analyze the potential of Bio-oss® optimized by the ultrasonic process and association with raloxifene in bone repair in rabbit maxillary sinus augmentation. The association of the researched materials was carried out by the ultrasonic process with 80% Bio-oss and 20% Raloxifene. Eight male rabbits (Oryctolagus cunilicus), six-months of age were subjected to a bilateral maxillary sinus lifting and, they were filled with biomaterials according to two groups, with four animals (eight maxillary sinus) per group: group 1 (BS) Biooss was subjected to ultrasonic process without raloxifene in both sinuses. Group 2 (BR) performed the application of the Bio-osssubjected to ultrasonic process together with raloxifene in both sinuses. The euthanasia of two animals for each group was performed two weeks after grafting, for histometric analysis of newly formed bone, connective tissue, and remaining material, and for immunohistochemical reactions using the primary antibody against Runx2. At 6 weeks, the other two animals for each group were euthanized to evaluate histomorphometric (HE), and immunohistochemical parameters for OCN, OPG, RANK -L, and TRAP. The results obtained showed superiority for the BS group, which presented more tissue organization in the period of 14 days, in addition to a greater amount of new bone tissue at 14-, and 42- days (P< 0.05). The immunohistochemical evaluation revealed a similarity between the scores for both groups, regardless of the time and protein analyzed. It is concluded that the addition of raloxifene, through the ultrasonic process, increases the inflammatory process in the initial period, reducing bone repair(AU)

Lip Synechia Resulting From Toxic Epidermal Necrolysis: A Rare Condition.

Toxic epidermal necrolyses represent a severe epidermolytic reaction characterized by cutaneous erythema and target lesions affecting >30% of the body surface, skin, and mucous membranes. Ulcerative lesions on the labial mucosa may evolve during healing, resulting in rare complications, such as lip adhesions. This report shows the successful treatment of a lip synechia resulting from the healing of mucosal lesions in a patient with toxic epidermal necrolysis caused by the use of Lamotrigine and Ibuprofen. Although the treatment of the presented lip synechia was simple, this sequela can be avoided by measures such as hydration, hygiene and lip lubrication.

Human bone morphogenetic protein-2 (hBMP-2) characterization by physical-chemical, immunological and biological assays.

Commercially available preparations of methionyl-human BMP-2 and CHO-derived hBMP-2, which belongs to the transforming growth factor ß (TGF-ß) superfamily, were used for a complete characterization. This protein is an extremely efficient osteoinductor that plays an important role during bone regeneration and embryonic development. Characterization was carried out via SDS-PAGE and Western blotting, followed by reversed-phase HPLC, size-exclusion HPLC and MALDI-TOF-MS. The classical in vitro bioassay, based on the induction of alkaline phosphatase activity in C2C12 cells, confirmed that hBMP-2 biological activity is mostly related to the dimeric form, being ~ 4-fold higher for the CHO-derived glycosylated form when compared with the E. coli counterpart. The E. coli-derived met-hBMP-2 has shown, by MALDI-TOF-MS, a large presence of the bioactive dimer. A more complex molecular mass (MM) distribution was found for the CHO-derived product, whose exact MM has never been reported because of its variable glycosylation. A method based on RP-HPLC was set up, allowing a quantitative and qualitative hBMP-2 determination even directly on ongoing culture media. Considering that hBMP-2 is highly unstable, presenting moreover an extremely high aggregate value, we believe that these data pave the way to a necessary characterization of this important factor when synthesized by DNA recombinant techniques in different types of hosts.

Strategy for the Treatment of Zygomatic-Coronoid Ankylosis.

Zygomatic-coronoid ankylosis is a rare complication in maxillofacial trauma. Currently, less of 30 cases reported in the literature. The aim of this study was to report a case of zygomatic-coronoid ankylosis after trauma. A 26-year-old male, with zygomatic-coronoid ankylosis after 7 years of facial trauma, was treated by intraoral bilateral coronoidectomy. However, the literature continues to discuss the best approach, intraorally or extraorally. This study observed that the intraoral approach was easily performed and without complications.
