Introduction:Sports’ practitioners are vulnerable to dental trauma; if this occurs, the emergency treatment should be fast and efficient. This may be performed by any person at the site of the accident, not only by dental professionals. Physical educators may face dental trauma and should be able to provide proper care. This study had the objective evaluated the knowledge of physical education graduates on dental trauma.Materials and Methods:A questionnaire containing questions on dental trauma was applied to 199 physical education students; after collection of the questionnaires, data were tabulated and processed on the software Epi Info 2000 (Centers for Disease Control and Prevention, 1600 Clifton Rd., Atlanta, GA 30333, USA). As a result, only 36.7% of participants would take the individual suffering trauma to the dental professional, 56.8% believe that the avulsed tooth should be replanted, and 42.2% would replant it. Only 7.5% would store the avulsed tooth in an ideal storage medium for transportation.Conclusion:It was concluded that there is a lack of knowledge on dental trauma among physical education graduates, evidencing the need of public policies to allow education on this issue.

Background/Aim Anti‐allergic drugs can inhibit the hard tissue resorption process, and due to similarities between root resorption and bone mechanisms, it can be inferred that these drugs may also control root resorption. The aim of this study was to analyze the effects of anti‐allergic drugs used systemically on the process of root resorption following delayed tooth replantation. Materials and Methods Thirty‐two maxillary right incisors of rats were extracted and subsequently replanted. Rats were divided into four groups according to the anti‐allergic drug administered: the rats in groups DEX, Q, and MO were treated systemically with dexamethasone phosphate, quercetin, and montelukast, respectively, and no systemic medication was administered to rats in group C. After 60 days, the animals were euthanized, and the specimens were processed for histomorphometric and immunohistochemical analyses. Statistical significance was set at P < .05. Results There were no significant differences between the groups in terms of inflammatory resorption, replacement resorption, or presence of tartrate‐resistant acid phosphatase. In terms of events occurring in the periodontal ligament space, there was a difference between groups Q and MO due to the presence of dental ankylosis and inflammatory connective tissue (P < .05). A difference in inflammatory cells was also observed through CD45 immunolabeling between the DEX and Q groups when compared to the C group (P < .05). Conclusion The systemic administration of anti‐allergic drugs did not have an effect on the process of root resorption following delayed tooth replantation.

To evaluate the influence of bioactive glass and photobiomodulation therapy (PBMT) in calvarial bone repair process in rats submitted to zoledronic acid therapy. Methods: Twenty-four rats were selected and treated with the dose of 0.035 mg/kg of zoledronic acid every two weeks, totalizing eight weeks, to induce osteonecrosis. After the drug therapy, surgical procedure was performed to create 5-mm diameter parietal bone defects in the calvarial region. The rats were then randomly assigned to groups according to the following treatments: AZC: control group, treated with blood clot;

Purpose:This study aimed to quantify, using cone-beam computed tomography (CBCT) in patients who underwent a mandibular advancement surgery associated with genioplasty, three-dimensional changes in airway space and to evaluate whether these changes differ between men and women.Materials and Methods:Preoperative and 8-month postoperative CBCT scans of 38 patients aged 18–45 years of either sex and any ethnicity who underwent mandibular advancement surgery associated with genioplasty were analyzed using the Xoran software (Xoran Technologies, Ann Arbor, MI, USA). The linear distances gonion-gnathion (Go-Gn) and condylion-menton (Co-Me) were obtained. Airway volume was measured using the Dolphin Imaging software, version 11.0. Then, data were tabulated and analyzed using Student's t-test.Results:Mean patient age was 30.3 years; 39.47% were men and 60.63% were women. The mean Go-Gn distance was 72.05 mm before surgery and 78.56 mm after surgery, with a mean gain of 6.51 mm. The mean Co-Me distance was 113.47 mm before surgery and 119.89 mm after surgery, with a mean increase of 6.42 mm. Both differences were statistically significant. The mean volume of airway space was 17,272.92 mm3 before surgery and 24,173.74 mm3 after surgery, with a statistically significant mean increase of 6900.82 mm3. There was no statistically significant difference in mean volumetric gain between men (7566.69 mm3) and women (7456.69 mm3).Conclusion:Mandibular advancement surgery results in significant increase of airway space, and there is no difference in airway volume between men and women.

Objective: Although hallux valgus is a common diagnosis and there are different well-described techniques for its correction, the presence of this deformity associated with a diagnosis of metatarsus adductus is relatively uncommon, and there is no consensus regarding surgical treatment. The objective of this study was to evaluate the preliminary radiographic results of angular corrections obtained in a series of cases of the surgical treatment of severe hallux valgus associated with adduction of the metatarsal bones, following the technique proposed herein. Methods: Retrospective data were collected from the medical records and pre- and postoperative radiographs of patients subjected to Lapidus arthrodesis combined with lateral rotation osteotomy at the bases of the second and third metatarsals. The following angular measurements were performed before and after surgery: hallux valgus angle, intermetatarsal angle, and the degree of adduction of metatarsal bones (measured by Sgarlato’s and Engel’s angles). The mean follow-up period was 18 months (16-24 months). Results: The mean hallux valgus correction angle was 31° (19-53°), and the mean intermetatarsal correction angle was 5.771° (2-9°). Regarding the forefoot adduction, the mean correction angle measured by the Sgarlato technique was 15.57° (12-21°) and by the Engel technique was 15.71° (10-22°). All of the measured angles decreased significantly in the postoperative assessment. Conclusion: Lapidus arthrodesis combined with rotational osteotomy at the bases of the second and third metatarsals proved to be effective for correcting the adduction of the metatarsals, allowing for the alignment of the first metatarsal and consequent correction of the deformity.
