Background/aim: Regenerative endodontic treatment is a promising approach for healing periapical lesions and continuous root maturation. Although previous studies have reported its outcomes, the dynamics of morphological changes over time remain unclear. Therefore, this study aimed to evaluate changes in the periapical status and root dimensions over a 60-month follow-up period.

Materials and methods: The follow-up duration, periapical status changes, calcific barrier formation, degree of apical closure and radiographic root area changes were compared with those of the last follow-up in this retrospective study. Radiographic root area changes were calculated as the difference between the total root and total canal areas.

Results: Fifty-eight patients (81 teeth) underwent regenerative endodontic treatment during the study period, of whom 32 patients (36 teeth, 62%) were included. The survival and success rates of the treated teeth were 100% and 94.4%, respectively. All teeth developed a calcific bridge in the cervical third of the root canal, indicating the presence of vital tissue. Apical narrowing (partial or total) was observed in 75% of the cases. The root maturation stage affected the percentage increase in the radiographic root area. Teeth in Cvek stages II-III showed a higher radiographic root area increase than more mature teeth. All tooth radiographic root areas increased significantly in the initial 20 months of the treatment and moderately thereafter.

Conclusions: Regenerative endodontic treatment is a safe approach for traumatised immature teeth. The presence of a radiographic calcified bridge may be an early indication of treatment success. The main complete tooth morphological changes occur after approximately 20 months posttreatment. These findings may help clinicians better understand the time-dependent changes in the root morphology after treatment, improve the follow-up schedule and predict the progress of healing during follow-up visits.

背景/目的:牙髓再生治疗是一种治愈根尖周病变并使牙根持续成熟的有效方法。虽然之前的研究已经报道了其结果,但形态变化的动态变化仍不清楚。因此,本研究旨在评估随访 60 个月期间根尖周状况和牙根尺寸的变化:在这项回顾性研究中,将随访时间、根尖周状况变化、钙化屏障形成、根尖闭合程度和根部X光片面积变化与最后一次随访进行了比较。根部X光片面积变化以根部总面积与根管总面积之差计算:研究期间,58 名患者(81 颗牙齿)接受了牙髓再生治疗,其中 32 名患者(36 颗牙齿,62%)接受了治疗。治疗后牙齿的存活率和成功率分别为 100%和 94.4%。所有牙齿的根管颈部三分之一处都出现了钙化桥,表明存在活力组织。75%的病例观察到根尖狭窄(部分或全部)。牙根成熟阶段会影响牙根放射面积的增加百分比。与更成熟的牙齿相比,处于 Cvek II-III 阶段的牙齿显示出更高的放射根部面积增长。在治疗的最初 20 个月中,所有牙齿的放射根部面积都有显著增加,之后则略有增加:再生牙髓治疗是治疗创伤性未成熟牙齿的一种安全方法。放射性钙化桥的出现可能是治疗成功的早期迹象。主要的完整牙齿形态变化发生在治疗后约 20 个月之后。这些发现可以帮助临床医生更好地了解治疗后牙根形态随时间的变化,改进随访计划并预测随访期间的愈合进展。

Background: Traumatic dental injuries related to sports are a significant concern, as they can have severe physical and psychological impacts on children. Using mouthguards is essential, particularly in sports like skating, where high-impact forces are common.

Aim: The study aimed to evaluate how stress is distributed on the teeth and surrounding bone in children with proclined anterior teeth when a force of 614.12 N was applied to two different regions of the jaws. The evaluation was conducted using finite element analysis (FEA), both with and without the use of a mouthguard.

Methods and methodology: A 3-dimensional finite element analysis (FEA) model was constructed using a cone beam computed tomography (CBCT) scan of a 12-year-old male patient. An average standardized force of 614.12 N was calculated, based on the average weight of children aged 11 to 13 years and the average speed of 13.4 m/s with which the children skate. The force was applied in two different directions and areas of the jaws: a lateral blow, perpendicular to the crown and root with the maxillary and mandibular teeth in occlusion (between the first molar and second premolar), and a blow obliquely at the pogonion point on the chin. Static simulations were then performed for four realistic scenarios-two with mouthguards and two without mouthguards.

Result: The Von Mises stresses were evaluated under all conditions. When the applied force was directed laterally, the stress values observed were 126.76 MPa with a mouthguard and 140 MPa without a mouthguard. When the force was applied to the chin region, the stress values were 37.997 MPa with a mouthguard and 40.67 MPa without a mouthguard.

Conclusion: The use of a mouthguard in children is beneficial for protecting teeth and surrounding structures, especially in cases of proclined anterior teeth, as it helps dampen the generated stresses.

背景:与体育运动有关的牙齿外伤是一个值得关注的重大问题,因为它们会对儿童的身体和心理造成严重影响。目的:本研究旨在评估当 614.12 牛顿的力作用于颌骨的两个不同区域时,前牙前突儿童牙齿和周围骨骼的应力分布情况。评估采用有限元分析法(FEA)进行,包括使用护齿器和不使用护齿器两种情况:使用一名 12 岁男性患者的锥形束计算机断层扫描 (CBCT) 扫描结果构建了一个三维有限元分析 (FEA) 模型。根据 11 至 13 岁儿童的平均体重和儿童滑冰的平均速度 13.4 米/秒计算出平均标准化力为 614.12 牛。该力施加在颌骨的两个不同方向和部位:垂直于上下颌牙齿咬合时牙冠和牙根(第一臼齿和第二前臼齿之间)的侧向打击,以及斜向打击下巴上的腭咽点。然后对四种实际情况进行了静态模拟--两种情况下使用护齿,两种情况下不使用护齿:结果:在所有条件下都对 Von Mises 应力进行了评估。当施加的力指向侧面时,观察到的应力值为:戴护齿时 126.76 兆帕,不戴护齿时 140 兆帕。当力作用在下巴区域时,佩戴护齿的应力值为 37.997 兆帕,不佩戴护齿的应力值为 40.67 兆帕:结论:儿童使用护齿器有利于保护牙齿和周围结构,尤其是在前牙前倾的情况下,因为它有助于抑制产生的应力。

Objectives: To examine families' experiences, including motivation and barriers to undergoing tooth autotransplantation (AT), and their perceptions of associated esthetic and functional outcomes.

Methods: Semi-structured, in-depth-interviews (IDIs) were conducted in person with families who had children that underwent the AT procedure. Interviews were audio recorded and transcribed. Transcripts were coded and thematically analyzed both deductively and inductively. A facilitators and barriers matrix and journey maps were created to draw inferences on patterns arising from main themes.

Results: Twenty families selecting AT as a solution for a missing maxillary incisor were recruited and interviewed. Overall, all families interviewed had a positive experience with the AT procedure. Motivating factors for undergoing the AT procedure included wanting an earlier intervention for the missing incisor, wishing to mitigate negative psychosocial effects, and the anticipated positive outcomes that would last into adulthood. Barriers to uptake of the AT procedure included the lack of dental practitioner awareness of AT as a potential solution and a large number of appointments and travel. Families were also initially concerned over potential complications that could arise from their child undergoing this procedure. The cost of the procedure was both a barrier and a facilitator for treatment.

Conclusions: The study results demonstrate that the overall AT is favorably considered by the families of growing children for the replacement of maxillary incisors and highlight factors that may act as motivators or barriers to its uptake.

目的研究家庭的经历,包括进行牙齿自体移植(AT)的动机和障碍,以及他们对相关美学和功能结果的看法:方法:对有孩子接受了自体牙移植手术的家庭进行了半结构式深度访谈(IDI)。访谈进行了录音和转录。对笔录进行编码,并以演绎和归纳的方式进行主题分析。我们创建了一个促进因素和障碍矩阵以及旅程地图,以便对主要主题所产生的模式进行推断:招募并采访了 20 个选择义齿替代技术作为上颌门牙缺失解决方案的家庭。总体而言,所有受访家庭对厌食症治疗过程都有积极的体验。接受磨牙术的动机包括希望更早地对门牙缺失进行干预、希望减轻负面的社会心理影响,以及预期将持续到成年期的积极效果。接受门牙反向矫正手术的障碍包括牙科医生对门牙反向矫正作为一种潜在的解决方案缺乏认识,以及大量的预约和旅行。家庭最初还担心孩子接受这种手术可能会引起并发症。手术费用既是治疗的障碍,也是治疗的促进因素:研究结果表明,成长中的儿童家庭在更换上颌门牙时,会积极考虑采用整体人工替代技术,并强调了一些可能成为接受该技术的动力或障碍的因素。

Aim: This study aimed to assess the validity and reliability of AI chatbots, including Bing, ChatGPT 3.5, Google Gemini, and Claude AI, in addressing frequently asked questions (FAQs) related to dental trauma.

Methodology: A set of 30 FAQs was initially formulated by collecting responses from four AI chatbots. A panel comprising expert endodontists and maxillofacial surgeons then refined these to a final selection of 20 questions. Each question was entered into each chatbot three times, generating a total of 240 responses. These responses were evaluated using the Global Quality Score (GQS) on a 5-point Likert scale (5: strongly agree; 4: agree; 3: neutral; 2: disagree; 1: strongly disagree). Any disagreements in scoring were resolved through evidence-based discussions. The validity of the responses was determined by categorizing them as valid or invalid based on two thresholds: a low threshold (scores of ≥ 4 for all three responses) and a high threshold (scores of 5 for all three responses). A chi-squared test was used to compare the validity of the responses between the chatbots. Cronbach's alpha was calculated to assess the reliability by evaluating the consistency of repeated responses from each chatbot.

Conclusion: The results indicate that the Claude AI chatbot demonstrated superior validity and reliability compared to ChatGPT and Google Gemini, whereas Bing was found to be less reliable. These findings underscore the need for authorities to establish strict guidelines to ensure the accuracy of medical information provided by AI chatbots.

目的:本研究旨在评估人工智能聊天机器人(包括 Bing、ChatGPT 3.5、Google Gemini 和 Claude AI)在解决牙科创伤相关常见问题(FAQ)时的有效性和可靠性:通过收集四个人工智能聊天机器人的回复,初步拟定了一套 30 个常见问题。然后,由牙髓病学专家和颌面外科医生组成的小组对这些问题进行了改进,最终选出了 20 个问题。每个问题在每个聊天机器人中输入三次,共产生 240 个回复。这些回复采用全球质量得分(GQS)进行评估,采用 5 点李克特量表(5:非常同意;4:同意;3:中立;2:不同意;1:非常不同意)。评分中的任何分歧均通过基于证据的讨论来解决。根据两个阈值:低阈值(所有三个回答的得分均≥ 4 分)和高阈值(所有三个回答的得分均为 5 分),将回答分为有效和无效两类,从而确定回答的有效性。使用卡方检验比较聊天机器人之间回复的有效性。计算了 Cronbach's alpha,通过评估每个聊天机器人重复回答的一致性来评估可靠性:结果表明,与 ChatGPT 和谷歌双子星相比,克劳德人工智能聊天机器人的有效性和可靠性更高,而必应的可靠性较低。这些研究结果表明,有关部门有必要制定严格的指导方针,以确保人工智能聊天机器人提供的医疗信息的准确性。

Background: Road traffic accidents have significantly impacted public health in Vietnam. This study investigated the patterns of midface fractures in Vietnam and their correlation with road traffic accidents in the country.

Methodology: This retrospective cross-sectional study reviewed 2187 medical records of patients with midface fractures in Ho Chi Minh City. After applying exclusion criteria, the fractures were categorized. Statistical analyses, including chi-squared and logistic regression, were conducted to identify associations and relationships among the types and causes of fractures.

Results: The study found that 89.3% of midface fractures stemmed from road traffic accidents, with 55.2% and 14.4% zygomatic complex fractures and Le Fort type II fractures, respectively. Adults aged 19-39 accounted for 65.1% of patients, with males at 80.5%. Traffic accidents were significantly associated with an 18.7 times higher risk of concomitant mandibular fractures and a 10.5 times higher risk of Le Fort type II fractures, irrespective of age and gender.

Conclusion: This study underscores the need for targeted prevention strategies to decrease the incidence of maxillofacial injuries resulting from road traffic accidents in Vietnam, particularly among high-risk groups such as males and young adults.

背景:道路交通事故严重影响了越南的公众健康。本研究调查了越南中面部骨折的模式及其与该国道路交通事故的相关性:这项回顾性横断面研究回顾了胡志明市 2187 名面中部骨折患者的医疗记录。在应用排除标准后,对骨折进行了分类。通过卡方和逻辑回归等统计分析,确定骨折类型和原因之间的关联和关系:研究发现,89.3%的中面部骨折源于道路交通事故,其中颧骨复合体骨折和 Le Fort II 型骨折分别占 55.2%和 14.4%。19-39岁的成年人占患者总数的65.1%,其中男性占80.5%。无论年龄和性别如何,交通事故与并发下颌骨骨折的风险高出18.7倍和Le Fort II型骨折的风险高出10.5倍明显相关:本研究强调,有必要制定有针对性的预防策略,以降低越南道路交通事故导致的颌面部损伤的发生率,尤其是男性和年轻人等高危人群。

Background: Sports dentistry aims to prevent and manage orofacial injuries, tooth fractures, tooth loss, and soft tissue trauma during sport activities. Mouthguards are appliances that protect athletes from dental trauma during contact sports. The video-sharing platform YouTube has a large number of informative videos about mouthguards. This study aimed to analyze the quality, accuracy, and reliability of YouTube videos about mouthguards, investigate the relationship between the features and the quality of mouthguard videos on YouTube, and provide suggestions for future informative content about mouthguards and sports dentistry.

Materials and methods: The first 100 videos for each keyword from YouTube were collected using the keywords "mouthguard," "sports mouthguard," and "mouthguard and dental trauma." Videos meeting the inclusion criteria were categorized based on publisher (dental professionals and nonprofessionals) and type (animation/slideshow, interview, and product introduction). Video features were recorded. Video content quality, reliability, and accuracy were measured by the Video Information and Quality Index (VIQI), the Journal of the American Medical Association (JAMA) benchmarks, the DISCERN Instrument, the Global Quality Scale (GQS), and the usefulness score. Data were analyzed using SPSS (IBM 29.0) at a 95% statistical significance level (p = 0.05).

Results: Out of 300 videos, 80 videos were included. Most of the videos were uploaded by dental professionals (n = 49). The average values of the VIQI, JAMA, DISCERN, and GQS scores were 15.33 out of 20.0, 1.38 out of 4.00, 49.24 out of 80.0, and 2.99 out of 5.00, respectively. Videos uploaded by dental professionals had significantly higher scores in VIQI, JAMA, DISCERN, GQS, and usefulness scores but exhibited a lower number of likes, comments, and views (p < 0.05). Of all included videos, 51% (n = 41) were categorized as "moderately useful" and 10% (n = 8) as "very useful."

Conclusions: Mouthguard videos uploaded by dental professionals are more useful, accurate, and of higher quality. Therefore, patients should consider the information shared by dental professionals. Greater participation from dentists in sharing high-quality content would be beneficial.

背景:运动牙科旨在预防和处理体育活动中的口面部损伤、牙齿骨折、牙齿脱落和软组织创伤。护齿是保护运动员在接触性运动中免受牙齿创伤的器具。视频共享平台 YouTube 上有大量关于护齿器的信息视频。本研究旨在分析 YouTube 上有关护齿器视频的质量、准确性和可靠性,研究 YouTube 上护齿器视频的特征与质量之间的关系,并为今后有关护齿器和运动牙科的信息内容提供建议:使用关键词 "护齿器"、"运动护齿器 "和 "护齿器和牙科创伤 "收集 YouTube 上每个关键词的前 100 个视频。符合纳入标准的视频根据发布者(牙科专业人士和非专业人士)和类型(动画/幻灯片、访谈和产品介绍)进行分类。对视频特征进行了记录。视频内容的质量、可靠性和准确性通过视频信息和质量指数(VIQI)、《美国医学会杂志》(JAMA)基准、DISCERN 仪器、全球质量量表(GQS)和实用性评分来衡量。数据使用 SPSS(IBM 29.0)进行分析,统计学显著性水平为 95% (p = 0.05):在 300 个视频中,有 80 个视频被收录。大多数视频是由牙科专业人员上传的(n = 49)。VIQI、JAMA、DISCERN 和 GQS 分数的平均值分别为 15.33(满分 20.0)、1.38(满分 4.00)、49.24(满分 80.0)和 2.99(满分 5.00)。牙科专业人士上传的护齿器视频更有用、更准确、质量更高。因此,患者应考虑牙科专业人士分享的信息。牙医更多地参与分享高质量的内容将是有益的。

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.

背景:牙外伤(DT)与跌倒有关联。另一方面,姿势平衡也与跌倒有关,并取决于身体调节系统的整合。本研究的目的是调查儿童牙外伤与正位平衡改变之间的潜在关系:这是一项基于人群的病例对照研究,涉及 296 名六岁学龄儿童。病例组包括曾患 DT 的儿童。对照组包括以前没有 DT 病史的儿童。稳定度测量是本研究的主要暴露指标。研究人员进行了逻辑回归分析,以估计发生几率方面的潜在差异:所审查的病例显示,在测量正立压力中心(COP)的前后轨迹速度时,当儿童闭眼时,平衡能力下降的几率为 4.37 倍。此外,在睁开眼睛并踩在泡沫垫上测量正压中心侧向摇摆时,平衡性降低的几率为 3.06 倍;在睁开眼睛并踩在泡沫垫上测量正压中心侧向摇摆宽度时,平衡性降低的几率为 4.00 倍:结论:与未受过外伤的儿童相比,有过DT病史的儿童在不同条件下出现正压平衡能力下降的几率更高。

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。

Background/aim: 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.

背景/目的:学龄前儿童牙槽骨突骨折的文献记载不多。牙槽突骨折的位置非常靠近基牙和恒牙牙胚。本研究调查了基牙牙槽突骨折愈合并发症的风险以及恒牙的潜在后遗症:本研究进行了一项回顾性队列研究,涉及牙槽突骨折的 21 名患者,共 49 颗基牙。随访方案包括在6岁前每隔一定时间进行临床和放射学检查。研究对乳牙的愈合并发症,如牙髓坏死、牙髓管阻塞、强直、感染相关的吸收和牙齿过早脱落进行了检查。在恒切牙萌出后,还对恒牙的后遗症进行了登记:在为期 3 年的随访中,牙槽突折裂后牙齿过早脱落的发生率为 51.2% [95% CI:34.1%-68.4%],牙髓管阻塞的发生率为 42.5% [95% CI:27.1%-57.8%],牙髓坏死的发生率为 8.9% [95% CI:0.6%-17.3%]。没有发现强直的病例。恒牙的后遗症主要包括分界不清和发育不全,估计风险分别为24% [95% CI:13%-39%] 和9% [95% CI:2%-21%]:结论:乳牙牙槽突骨折与乳牙的多种愈合并发症有关。虽然恒牙出现严重并发症的可能性较低,但幼儿仍然很容易在恒牙中出现后遗症。这些结果突显了认识原牙槽突骨骨折后牙齿损伤的重要性。

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.

背景/目的:纵向队列研究尚未对耳朵问题与牙外伤(TDI)之间的关系进行研究。本研究旨在估算耳朵问题对澳大利亚土著儿童乳牙和恒牙外伤的影响:土著儿童纵向研究 "是一项针对两个具有代表性的澳大利亚土著儿童队列的研究,这些儿童的基线年龄分别为 6 个月至 2 岁(婴儿队列)或 3.5 至 5 岁(儿童队列)(2008 年)。儿童的母亲/主要照顾者在 2008 年接受了一次面对面的访谈,在接下来的 9 年中每年重复一次。耳部问题包括流鼻涕、鼓膜穿孔、全聋、单耳聋、听力损失/半聋以及其他耳部问题。TDI包括牙齿和口腔软硬组织损伤。分析中采用了多变量生存分析,并使用考克斯比例回归模型估算了危险比(HR):共有 870 名婴儿队列和 668 名儿童队列的土著儿童被纳入分析,他们在基线时没有 TDIs。总队列、婴儿队列和儿童队列中的 TDI 患病率分别为 9.2%、11.1% 和 6.6%。TDIs的多变量模型显示,有耳部问题的儿童随着时间的推移,其平均危害是没有耳部问题的儿童的近4倍(总体:HR = 3.72,95% CI:1.82-6.77)、5倍(婴儿队列:HR = 4.76,95% CI:1.59-11.63)和15倍以上(儿童队列:HR = 16.2,95% CI:4.78-49.28)。对所有协变量进行调整后,在儿童队列中,有耳疾的儿童的 TDI 是无耳疾儿童的 22 倍多(HR = 22.03,95% CI:4.50-87.07)。教育水平较低的母亲/主要照顾者与 TDIs 的发生率呈正相关:结论:在两个大型澳大利亚土著儿童队列中,耳朵问题是导致TDI发病率增加的一个风险指标。母亲/主要照护者的教育水平是导致TDIs的重要风险因素。
