Background: Dental trauma (DT) and falls have shown to be associated. On the other hand, postural balance is associated with falls and depends on the integration of the body's regulatory systems. The aim of this study was to investigate the potential relationship between DT and alteration of orthostatic balance in children.
Methods: This was a population-based case-control study involving 296 six-year-old schoolchildren. The case group included children with previous history of DT. The control group included children with no previous history of DT. Stabilometric measurements were the main exposure of this study. Logistic regression analyzes were performed to estimate potential differences in terms of chance of occurrence.
Results: The cases reviewed showed a 4.37 times chance of reduced balance in the measurement of the anteroposterior trajectory speed of the orthostatic center of pressure (COP), when children had their eyes closed. It also presented a chance of 3.06 times reduced balance in the measurement of the orthostatic center of pressure latero-lateral sway, with children with open eyes and stepping on a foam pad, and 4.00 times of reduced balance in the width of the latero-lateral sway of the orthostatic center of pressure, with children with open eyes and stepping on a foam pad.
Conclusion: Children with previous history of DT showed a higher chance of experiencing a reduced orthostatic balance in different conditions when compared to children without the occurrence of trauma.

Autotransplantation of teeth (ATT) is a viable treatment option for replacing teeth lost due to various reasons. Periodontal ligament (PDL) on the donor tooth is one of the most crucial factors determining the success of ATT. To preserve the PDL during surgery and improve the success rate of ATT, digital dentistry has been applied to ATT. In this article, a digital workflow including surgical simulation, a three-dimensional (3D) replica fabrication, and a novel osteotomy guide design is introduced. Digital simulation of ATT on a patient's integrated model enables visualization of anatomical structures and the 3D position of the donor tooth prior to the actual surgery. The 3D-printed osteotomy guide allows the transfer of the direction and depth of the planned osteotomy into the intraoral environment. The 3D replica helps prepare the recipient site before the actual transplantation, which minimizes the extra-alveolar time of the donor tooth and decreases trauma during the try-in process. The proposed virtual planning and the use of the guide and the 3D replica can facilitate the surgical procedures while minimizing complications.
牙齿自体移植（ATT）是替代因各种原因导致的牙齿缺失的可行治疗方案。供体牙齿上的牙周韧带（PDL）是决定 ATT 成功与否的最关键因素之一。为了在手术过程中保留牙周韧带并提高 ATT 的成功率，数字化牙科技术已被应用于 ATT。本文介绍了一种数字化工作流程，包括手术模拟、三维（3D）复制品制作和新型截骨导板设计。在患者的综合模型上对 ATT 进行数字模拟，可以在实际手术前将解剖结构和供体牙齿的三维位置可视化。三维打印的截骨导板可将计划截骨的方向和深度转移到口腔内环境中。三维复制品有助于在实际移植前准备受体部位，从而最大限度地减少供体牙齿的牙槽外时间，并减少试戴过程中的创伤。拟议中的虚拟规划以及导板和三维复制品的使用可以促进手术过程，同时最大限度地减少并发症。

Alveolar bone process fractures in preschool children are not well documented in the literature. Alveolar process fractures are located very close to primary teeth and permanent tooth germs. This study investigates the risk of healing complications following alveolar process fractures in the primary dentition and potential sequelae in the permanent dentition.
Materials and Methods
A retrospective cohort study was conducted involving 21 patients with 49 primary teeth involved in an alveolar fracture. The follow-up protocol included clinical and radiographic examinations at specified intervals up to the age of 6 years. Healing complications in the primary teeth such as pulp necrosis, pulp canal obliteration, ankylosis, infection-related resorption and premature tooth loss were examined. Sequelae in the permanent dentition was also registered when the permanent incisors had erupted.
Results
Over a 3-year follow-up, the incidence of premature tooth loss was 51.2% [95% CI: 34.1%–68.4%], pulp canal obliteration was 42.5% [95% CI: 27.1%–57.8%], and pulp necrosis was 8.9% [95% CI: 0.6%–17.3%] following an alveolar process fracture. No cases of ankylosis were observed. Sequelae in the permanent dentition primarily included demarcated opacities and hypoplasia with a risk estimated at 24% [95% CI: 13%–39%] and 9% [95% CI: 2%–21%] respectively.
Conclusion
Alveolar process fractures in primary dentition are associated with several healing complications in the primary teeth. Although the likelihood of severe complications in the permanent dentition is low, young children are still susceptible to developing sequelae in their permanent teeth. These results highlight the importance of awareness of dental injuries following alveolar process bone fractures in the primary dentition.

Background/Aim
The association between ear problems and traumatic dental injuries (TDIs) has not been examined in longitudinal cohort studies. The study aimed to estimate the effect of ear problems on TDIs in primary and permanent teeth among Australian Indigenous children.
Methods
The Longitudinal Study of Indigenous Children is a study of two representative cohorts of Indigenous Australian children, aged from 6 months to 2 years (baby cohort) or from 3.5 to 5 years (child cohort) at baseline (2008). The children's mother/primary carer undertook a face-to-face interview in 2008, repeated annually for the next 9 years. Ear problems included runny ears, perforated eardrum, total deafness, deaf in one ear, hearing loss/partially deaf, and other ear problems. TDIs were teeth and oral soft and hard tissue injuries. Multivariate survival analysis using Cox proportional regression models estimated hazards ratio (HR) were used in the analysis.
Results
A total of 870 from baby cohort and 668 from child cohort Indigenous children, who had no TDIs at baseline were included in the analysis. The prevalence of TDIs was 9.2%, 11.1%, and 6.6% in the total, baby, and child cohorts, respectively. Multivariable models for TDIs indicate children with ear problems had nearly four times (total: HR = 3.72, 95% CI: 1.82–6.77), five times (baby cohort: HR = 4.76, 95% CI: 1.59–11.63), and more than 15 times (child cohort: HR = 16.2, 95% CI: 4.78–49.28) the average hazard over time, than those without ear problems. After adjusting for all covariates, children with ear problems had more than 22 times (HR = 22.03, 95% CI: 4.50–87.07) TDIs than those without ear problems in the child cohort. Mothers/primary carers with lower educational level was positively associated with the incidence of TDIs.
Conclusion
Ear problems were a risk indicator for the increased incidence of TDIs in two large cohorts of Indigenous Australian children. Mothers/primary carers' educational level was a significant risk factor for TDIs.

This study explored perceived challenges in the management of traumatic dental injuries (TDI) among general dentists in the public dental service (PDS) of Vestland County in Western Norway and their needs for improving treatment care for TDI patients.
Participants and Methods
This qualitative study conducted three focus group discussions. We recruited a purposive sample of seven general dentists employed in the PDS in Vestland County in Western Norway. The three focus groups consisted of two, two, and three participants, respectively. The focus group discussion took place via the Microsoft electronic platform Teams, and it was visual, and audio recorded. Transcripts of the interviews were analyzed using systematic text condensation.
Results
The general dentists in this study experienced the management of TDI as a set of complex procedures that require good theoretical knowledge, clinical experience, skills, and teamwork. We were able to group these challenges into three results categories: (1) proficiency challenges, (2) the challenge of stress and discomfort during dental procedures, and (3) the challenge of the organization of the PDS. The participants also expressed the need for practical courses, calibration, and refresher courses in dental traumatology. Their needs fell into two categories: (1) regular, clinically relevant continuing professional development and (2) collective efforts in TDI management.
Conclusion
Increasing awareness of the challenges in TDI management and addressing the need for improved dental treatment for TDI patients may lead to targeted programs to enhance dentists' knowledge and skills. There is considerable potential for training dentists in dental traumatology.

Background/Objectives
The use of different models for the fabrication of custom-fit mouthguards (MTGs) can affect their final thickness, adaptation, and shock-absorption properties. This study aimed to evaluate the adaptation, thickness, and shock absorption of ethylene-vinyl acetate (EVA) thermoplastic MTGs produced using conventional plaster or three-dimensional (3D) printed models.
Materials and Methods
A typical model with simulated soft gum tissue was used as the reference model to produce MTGs with the following two different protocols: plast-MTG using a conventional impression and plaster model (n = 10) and 3DPr-MTG using a digital scanning and 3D printed model (n = 10). A custom-fit MTG was fabricated using EVA sheets (Bioart) plasticized over different models. The MTG thickness (mm), internal adaptation (mm) to the typodontic model, and voids in the area (mm2) between the two EVA layers were measured using cone-beam computed tomography images and Mimics software (Materialize). The shock absorption of the MTG was measured using a strain-gauge test with a pendulum impact at 30° with a steel ball over the typodont model with and without MTGs. Data were analyzed using one-way analysis of variance with repeated measurements, followed by Tukey's post hoc tests.
Results
The 3DPr-MTG showed better adaptation than that of the Plast-MTG at the incisal/occlusal and lingual tooth surfaces (p < 0.001). The 3DPr-MTG showed a thickness similar to that of the Plast-MTG, irrespective of the measured location. MTGs produced using both model types significantly reduced the strain values during horizontal impact (3DPr-MTG 86.2% and Plast-MTG 87.0%) compared with the control group without MTG (p < 0.001).
Conclusion
The MTGs showed the required standards regarding thickness, adaptation, and biomechanical performance, suggesting that the number and volume of voids had no significant impact on their functionality. Three-dimensional printed models are a viable alternative for MTG production, providing better adaptation than the Plast-MTG at the incisal/occlusal and lingual tooth surfaces and similar performance as the MTG produced with the conventional protocol.

Aim
To evaluate the impact of acquisition protocols and artifact reduction filters in cone beam computed tomography on diagnosing vertical root fractures in endodontically treated teeth with and without intraradicular posts.
Materials and Methods
We analyzed 480 tomographic images acquired from two J. Morita scanners (0.125- and 0.08-mm voxel sizes protocols), with application of a blooming artifact reduction filter. Three evaluators assessed these images for root fractures using a 5-point Likert scale. Diagnostic accuracy between filters and protocols was determined using generalized linear models with binomial distribution for the outcome, considering protocol, filter, and dental status. Sensitivity, specificity, positive predictive value, and negative predictive value were also estimated for the filters and protocols.
Results
The 0.08-mm voxel size protocol demonstrated a significantly higher percentage of accurate diagnosis compared to the 0.125-mm protocol (p = .001). No statistically significant differences (p ≥ .087) were observed for filter application, interaction between protocol and filter, or dental status. Accuracy, sensitivity, and specificity values were respectively: .93, .87, 1.00 (protocol 1); .99, .99, .99 (protocol 2); .98, .96, .99 (no filter); .95, .90, 1.00 (with filter).
Conclusion
The new findings found for the two J Morita scanners used in our study were that images acquired using the voxel size of 0.08 mm showed an improvement in the diagnosis of root fractures and the filters in these devices have no relevance significant for the diagnosis.

Bodybuilding and cross-training exercises bring health benefits. However, orofacial injuries can occur during practice. This study aimed to map, analyze, interpret, and synthesize data from studies on the main orofacial injuries resulting from bodybuilding and cross-training practices. This scoping review followed the Joanna Briggs Institute and PRISMA-ScR methods, with high-sensitivity searches in PubMed, Web of Science, Scopus, ScienceDirect, Embase, Virtual Health Library and the Google Scholar. Original scientific articles published up to May 2024 were included, which evaluated the presence of self-reported or professionally diagnosed orofacial injuries by bodybuilding and cross-training practitioners aged 18 years or older. Literature reviews, editorials, and guidelines were excluded. Tables and figures were used to map and summarize the results. Out of 30.485 potentially eligible articles, four were included. The main orofacial injuries identified in both bodybuilding and cross-training practitioners were dental damage (n = 4), temporomandibular joint (TMJ) disorders (n = 3), and traumas to oral soft tissues (n = 2) and facial soft tissues (n = 2). Dental damage and TMJ disorders were the most prevalent conditions among bodybuilding and cross-training practitioners. Therefore, dental damage and TMJ disorders were the most prevalent conditions among bodybuilding and cross-training practitioners. However, further prospective studies with more in-depth methodological designs and fewer biases are necessary.
健美运动和交叉训练对健康有益。然而，在练习过程中也可能发生口面部损伤。本研究旨在绘制、分析、解释和综合有关健美和交叉训练导致的主要口面部损伤的研究数据。本次范围界定综述遵循 Joanna Briggs Institute 和 PRISMA-ScR 方法，在 PubMed、Web of Science、Scopus、ScienceDirect、Embase、Virtual Health Library 和 Google Scholar 中进行了高灵敏度检索。收录了截至 2024 年 5 月发表的原创科学文章，这些文章评估了 18 岁或以上健美和交叉训练从业人员自我报告或专业诊断的口面部损伤情况。不包括文献综述、社论和指南。使用表格和图表对结果进行映射和总结。在 30 485 篇可能符合条件的文章中，有 4 篇被收录。在健美和交叉训练从业者中发现的主要口面部损伤是牙齿损伤（4 例）、颞下颌关节（TMJ）疾病（3 例）、口腔软组织创伤（2 例）和面部软组织创伤（2 例）。牙齿损伤和颞下颌关节紊乱是健美和交叉训练从业者中最常见的疾病。因此，牙齿损伤和颞下颌关节紊乱是健美和交叉训练练习者中最常见的病症。不过，有必要进一步开展前瞻性研究，采用更深入的方法设计，减少偏差。

The delayed re-implantation of avulsed teeth results in ankylosis, followed by replacement resorption and eventual loss of the tooth within 2–4 years. To prevent tooth loss, the root surface can be etched with acid to expose the collagen fibers present in the cementum layer. This process facilitates normal reattachment and regeneration of the periodontal ligament. This in-vitro study aimed to assess the viability and number of attached cultured Human Periodontal Ligament Cells (HPLC) on the dehydrated root surface of simulated avulsed teeth treated with citric acid and EDTA solutions.
Materials and Methods
Sound human permanent teeth were included in the study. The root portions of the teeth were sectioned into slices, air-dried for 1 h, and divided into the following three groups: Group A–control; Group B–Citric acid treated for 30 min; Group C–EDTA treated for 5 min. The slices were then placed in cultured HPLC. After a 24-h incubation period, the slices were visualized under the microscope and prepared for reading the viable and dead HPLC using a spectrofluorometer, as well as for counting HPLC in a Neubauer Chamber.
Results
The spectrofluorometer intensity for viable and dead HPLC showed a statistically significant difference (p = .003 and p = .002), with the mean intensity for viable HPLC greater in citric acid group (69.52 ± 74.51), followed by EDTA group (31.39 ± 9.12), and control group (−130.93 ± 30.99). The dead HPLC intensity was greater in the EDTA group (19.43 ± 47.31), followed by the citric acid group (1.28 ± 1.85), and the control group (−2.77 ± 0.76). The total number of cells in the Neubauer chamber showed a statistically significant difference (p < 0.001), with a higher count in the citric acid group (10.83 ± 4.08) followed by EDTA group (2.92 ± 2.92).
Conclusion
The application of citric acid for 30 min on the dehydrated root surface of avulsed teeth demonstrated superior outcomes compared to both EDTA treatment for 5 min and the control group.
