Background: The aim of the present study was to investigate qualitatively and quantitatively the elution of substances from polyester-urethane (Invisalign™) aligners and resin composite attachments (Tetric EvoFlow) in vivo.

Methods: Patients (n = 11) treated with the aligners and attachments (16 per patient, without other composite restorations) for an average of 20 months, who were planned for attachment removed were enrolled in the study. Patients were instructed to rinse with 50 mL of distilled water upon entry and the rinsing solution was collected (before removal). Then, the attachments were removed with low-speed tungsten carbide burs for adhesive residue removal, a thorough water rinsing was performed immediately after the grinding process to discard grinding particle residues, and subsequently, after a second water-rinsing the solution was collected for analysis (after removal). The rinsing solutions were analyzed for targeted (LC-MS/MS: Bis-GMA, DCDMA, UDMA, BPA) and untargeted (LC-HRMS: screening of leached species and their degradation products) compounds.

Results: Targeted analysis revealed a significant reduction in BPA after attachment removal (4 times lower). Bis-GMA, DCDMA, UDMA were below the detection limit before removal but were all detectable after removal with Bis-GMA and UDMA at quantifiable levels. Untargeted analysis reviled the presence of mono-methacrylate transformation products of Bis-GMA (Bis-GMA-M1) and UDMA (UDMA-M1), UDMA without methacrylate moieties (UDMA-M2), and 4-(dimethylamino) benzoic acid (DMAB), the degradation product of the photo-initiator ethyl-4-(dimethylamino) benzoate (EDMAB), all after attachment removal. Several amino acids and endogenous metabolites were also found both before and after removal.

Conclusions: Elevated levels of BPA were traced instantaneously in patients treated with Invisalign™ and flowable resin composite attachments for the testing period. BPA was reduced after attachment removal, but residual monomers and resin degradation products were found after removal. Alternative resin formulations and attachment materials may be utilized to reduce eluents.

背景:本研究旨在对聚酯-聚氨酯(Invisalign™)矫治器和树脂复合附着体(Tetric EvoFlow)在体内的物质洗脱进行定性和定量研究:参加研究的患者(n = 11)平均接受了 20 个月的矫正器和附着体治疗(每位患者 16 个,无其他复合修复体),并计划去除附着体。患者在入院时被告知用 50 毫升蒸馏水冲洗,并收集冲洗液(在摘除前)。然后,使用低速碳化钨车针去除粘合剂残留物,磨削过程结束后立即进行彻底的水冲洗以丢弃磨削颗粒残留物,随后,在第二次水冲洗后收集溶液进行分析(去除后)。对漂洗溶液进行了目标化合物(LC-MS/MS:Bis-GMA、DCDMA、UDMA、BPA)和非目标化合物(LC-HRMS:筛选浸出物及其降解产物)分析:结果:靶向分析表明,去除附着物后,双酚 A 的含量明显降低(低 4 倍)。双-GMA、DCDMA 和 UDMA 在去除前低于检测限,但在去除后都能检测到,其中双-GMA 和 UDMA 达到了可量化的水平。非目标分析显示,在去除附着物后,还存在双-GMA(Bis-GMA-M1)和 UDMA(UDMA-M1)的单甲基丙烯酸酯转化产物、不含甲基丙烯酸酯的 UDMA(UDMA-M2)以及光引发剂乙基-4-(二甲基氨基)苯甲酸(EDMAB)的降解产物 4-(二甲基氨基)苯甲酸(DMAB)。在去除附着物前后,还发现了几种氨基酸和内源性代谢物:在使用隐适美™和可流动树脂复合附着体进行治疗的患者中,检测到双酚 A 含量瞬间升高。去除附着物后,双酚 A 的含量有所降低,但去除后仍可发现残留的单体和树脂降解产物。可以使用其他树脂配方和附件材料来减少洗脱物。

Background: Skeletal anterior open bite (SAOB) represents one of the most complex and challenging malocclusions in orthodontics. Orthodontic treatment supported by miniplates enable to reduce the need for orthognathic surgery. Transverse dimension may be affected by intrusion biomechanics. This study aims to assess transverse bone alterations in patients with SAOB who underwent orthodontic treatment with absolute anchorage using four miniplates.

Methods: A total of 32 patients of both sexes, with an average age of 33.8 years, diagnosed with SAOB and treated orthodontically with four miniplates (one in each hemiarch), were selected for this study. Tomographic examinations were performed before (T1) and after (T2) orthodontic treatment. Linear measurements (width of the maxillary base, maxillary alveolar, maxillary root, maxillary dental cusp, mandibular alveolar) and angular measurements (maxillary intermolar angle) were assessed in these images. The Shapiro-Wilks normality tests were applied to verify data distribution, and the paired t-test was used to compare the initial and final measures obtained.

Results: Among the evaluated parameters, the maxillary alveolar width, maxillary dental cusp width, mandibular alveolar cusp width, and intermolar angle showed statistically significant differences between T1 and T2 (p < 0.05). However, maxillary base and maxillary root widths showed no significant difference (p > 0.05).

Conclusions: Intrusion and distalization with miniplates in SAOB therapy may lead to significant expansive changes, due to molars cusps width and buccal inclination increase restricted at the alveolar level.

背景:骨骼前方开放性咬合(SAOB)是正畸学中最复杂、最具挑战性的错颌畸形之一。微型托槽支持的正畸治疗可以减少正颌外科手术的需要。横向尺寸可能会受到入侵生物力学的影响。本研究旨在评估使用四个微型托槽进行绝对固定正畸治疗的 SAOB 患者的横向骨改变情况:本研究共选取了 32 名患者,男女均有,平均年龄 33.8 岁,均被诊断为 SAOB,并接受了四个微型托槽(每个半弓一个)的正畸治疗。在正畸治疗前(T1)和治疗后(T2)分别进行了断层扫描检查。在这些图像中评估了线性测量值(上颌基底宽度、上颌牙槽宽度、上颌牙根宽度、上颌牙尖宽度、下颌牙槽宽度)和角度测量值(上颌磨间角)。采用 Shapiro-Wilks 正态性检验来验证数据分布,并用配对 t 检验来比较初始和最终测量结果:在评估的参数中,上颌牙槽宽度、上颌牙尖宽度、下颌牙槽尖宽度和磨间角在 T1 和 T2 之间存在显著的统计学差异(P 0.05):结论:在SAOB治疗中使用迷你板进行内收和远端化可能会导致明显的扩张性改变,这是因为臼齿尖牙宽度和颊倾角的增加在牙槽水平受到了限制。

Backgrounds and objectives: The present study was designed to define a novel algorithm capable of predicting female adolescents' cervical vertebrae maturation stage with high recall and accuracy.

Methods: A total of 560 female cephalograms were collected, and cephalograms with unclear vertebral shapes and deformed scales were removed. 480 films from female adolescents (mean age: 11.5 years; age range: 6-19 years) were used for the model development phase, and 80 subjects were randomly and stratified allocated to the validation cohort to further assess the model's performance. Derived significant predictive parameters from 15 anatomic points and 25 quantitative parameters of the second to fourth cervical vertebrae (C2-C4) to establish the ordinary logistic regression model. Evaluation metrics including precision, recall, and F1 score are employed to assess the efficacy of the models in each identified cervical vertebrae maturation stage (iCS). In cases of confusion and mispredictions, the model underwent modification to improve consistency.

Results: Four significant parameters, including chronological age, the ratio of D3 to AH3 (D3:AH3), anterosuperior angle of C4 (@4), and distance between C3lp and C4up (C3lp-C4up) were administered into the ordinary regression model. The primary predicting model that implements the novel algorithm was built and the performance evaluation with all stages of 93.96% for accuracy, 93.98% for precision, 93.98% for recall, and 93.95% for F1-score were obtained. Despite the hybrid logistic-based model achieving high accuracy, the unsatisfactory performance of stage estimation was noticed for iCS3 in the primary cohort (89.17%) and validation cohort (85.00%). Through bivariate logistic regression analysis, the posterior height of C4 (PH4) was further selected in the iCS3 to establish a corrected model, thus the evaluation metrics were upgraded to 95.83% and 90.00%, respectively.

Conclusions: An unbiased and objective assessment of the cervical vertebrae maturation (CVM) method can function as a decision-support tool, assisting in the evaluation of the optimal timing for treatment in growing adults. Our novel proposed logistic model yielded individual formulas for each specific CVM stage and attained exceptional performance, indicating the capability to function as a benchmark for maturity evaluation in clinical craniofacial orthopedics for Chinese female adolescents.

背景和目的:本研究旨在确定一种新型算法,该算法能够以较高的回忆率和准确率预测女性青少年的颈椎成熟阶段:方法:共收集了 560 张女性头颅照片,剔除了椎体形状不清晰和刻度变形的头颅照片。模型开发阶段使用了 480 张来自女性青少年(平均年龄:11.5 岁;年龄范围:6-19 岁)的照片,并将 80 名受试者随机分层分配到验证队列中,以进一步评估模型的性能。从第二至第四颈椎(C2-C4)的 15 个解剖点和 25 个定量参数中提取重要的预测参数,建立普通逻辑回归模型。采用包括精确度、召回率和 F1 分数在内的评价指标来评估模型在每个已确定的颈椎成熟阶段(iCS)中的功效。在出现混淆和预测错误的情况下,对模型进行修改以提高一致性:结果:在普通回归模型中加入了四个重要参数,包括实际年龄、D3与AH3的比率(D3:AH3)、C4的前上角(@4)以及C3lp与C4up之间的距离(C3lp-C4up)。建立了采用新算法的主要预测模型,并获得了准确率为 93.96%、精确率为 93.98%、召回率为 93.98%、F1 分数为 93.95%的各阶段性能评估。尽管基于混合逻辑的模型获得了较高的准确率,但 iCS3 在初选队列(89.17%)和验证队列(85.00%)中的阶段估计表现并不令人满意。通过双变量逻辑回归分析,在 iCS3 中进一步选择了 C4 后高度(PH4)来建立修正模型,因此评价指标分别提升至 95.83% 和 90.00%:对颈椎成熟度(CVM)的无偏见客观评估方法可作为决策支持工具,帮助评估生长期成年人的最佳治疗时机。我们提出的新逻辑模型为每个特定的颈椎成熟阶段提供了单独的公式,并取得了优异的成绩,表明该模型能够作为中国女性青少年颅面矫形临床成熟度评估的基准。

Background: Low-intensity electrical stimulation (LIES) is considered a relatively recent technology that has received little attention in orthodontics as a method of acceleration. This study aimed to evaluate patient-reported outcome measures when LIES is used to accelerate the en-masse retraction of the upper anterior teeth.

Materials and methods: The sample consisted of 40 patients (8 males, 32 females; mean age 21.1 ± 2.3 years), with Class II division I malocclusion who required extraction of the first premolars to retract upper anterior teeth. They were randomly assigned to the LIES group (n = 20) and the conventional en-masse retraction group (CER; n = 20). Patient responses regarding pain, discomfort, burning sensation, swelling, chewing difficulty, speech difficulty, and painkillers' consumption were recorded at these nine assessment times: 24 h (T1), 3 days (T2), and 7 days (T3) after force application, then in the second month after 24 h (T4), 3 days (T5), and 7 days (T6) of force re-activation, and finally after 24 h (T7), 3 days (T8), and 7 days (T9) of force re-activation in the third month.

Results: The mean values of pain perception were smaller in the LIES group than those in the CER group at all assessment times with no statistically significant differences between the two groups except during the second and third months (T5, T6, T8, and T9; P < 0.005). However, discomfort mean values were greater in the LIES group with significant differences compared to CER group during the first week of the follow-up only (T1, T2, and T3; P < 0.005). Burning sensation levels were very mild in the LIES group, with significant differences between the two groups at T1 and T2 only (P < 0.001). Speech difficulty was significantly greater in the LIES group compared to CER group at all studied times (P < 0.001). High levels of satisfaction and acceptance were reported in both groups, without any significant difference.

Conclusion: Both the LIES-based acceleration of en-masse retraction of upper anterior teeth and the conventional retraction were accompanied by mild to moderate pain, discomfort, and chewing difficulty on the first day of retraction. These sensations gradually decreased and almost disappeared over a week after force application or re-activation.

Objective: This study aimed to investigate orthodontists' utilization and perceptions of tele-orthodontics.

Materials and methods: A 30-item online survey was distributed to members of the American Association of Orthodontists (AAO). The questionnaire encompassed topics concerning the orthodontists' utilization, perceptions, clinical applications, limitations, and concerns regarding tele-orthodontics. Descriptive statistics were employed, and comparisons between responses from users and non-users were conducted  using Wilcoxon rank-sum tests and Fisher's exact tests.

Results: 152 members completed the survey, (response rate: 2.4%). More than two third of respondents (69.74%) were users of tele-orthodontics. Users were more aligned with the belief that tele-orthodontics facilitates effective communication (mean ± standard deviation (SD) 4.06 ± 0.83 vs. 3.33 ± 0.94, p < 0.001). Both groups agreed on the requirement of patient fees for tele-orthodontic visits (mean ± SD: 3.62 ± 1.11 users vs. 3.74 ± 1.02 non-users, p = 0.659), and on the capability  of the system to reduce unwarranted referrals (p = 0.20). The majority of participants acknowledged  the utility of the system in monitoring aligners' patients (89% in users vs. 61% in non-users, p < 0.001). Non-users expressed greater concerns regarding privacy risks (mean ± SD: 3.06 ± 0.97 users vs. 3.57 ± 0.86 non-users, p = 0.002). Both groups stressed the significance of obtaining informed consent before utilizing tele-orthodontics.

Conclusions: The widespread acceptance of tele-orthodontics among AAO members was apparent, as demonstrated by their recognition of its effectiveness. There was notable variation in how users and non-users perceived tele-orthodontics. The study's results offer valuable insights into both the potential benefits and drawbacks of incorporating this technology into clinical practice from the clincians' perspective.

研究目的本研究旨在调查正畸医生对远程正畸的使用情况和看法:向美国口腔正畸医师协会(AAO)成员发放了一份包含 30 个项目的在线调查问卷。问卷内容包括正畸医生对远程正畸的使用情况、看法、临床应用、局限性和担忧。调查采用了描述性统计方法,并使用 Wilcoxon 秩和检验和费雪精确检验对用户和非用户的回答进行了比较:152 名成员完成了调查(回复率:2.4%)。超过三分之二的受访者(69.74%)是远程正畸的使用者。用户更认同远程正畸有助于有效沟通的观点(平均值±标准差(SD)为 4.06±0.83 vs. 3.33±0.94, p 结论:远程正畸被广泛接受的原因是,远程正畸可以帮助牙科医师与患者进行有效的沟通:AAO成员对远程正畸的广泛接受是显而易见的,他们对其有效性的认可也证明了这一点。用户和非用户对远程正畸的看法存在明显差异。研究结果提供了宝贵的见解,从医生的角度说明了将该技术纳入临床实践的潜在好处和缺点。

This study aims to compare the impact of pain on quality of life and patient satisfaction during treatment with aligners. Ninety-four subjects in active treatment were invited to answer self-reported questions concerning pain severity and duration, occurrence of other signs and symptoms, and level of satisfaction with their treatment. Also, the OHIP-14 questionnaire was applied to assess patients’ OHRQoL. Ninety-four patients (49 women and 45 men) answered the survey. Pain duration of 1–3 days was reported by 69.1% of patients (n = 60). For those who reported pain (n = 84), it was considered mild severity by 42.9% and moderate by 52.4%. Almost sixty-four percent of the sample were very satisfied with the aligner’s aesthetics (n = 60) and forty-nine percent were satisfied with treatment in general (n = 46). Mean OHIP-14 score was 3.36 ± 2.54. OHRQoL was significantly associated with pain severity, whereas patients who reported having experienced moderate pain presented a significantly higher mean OHIP-14 score than those who reported having experienced mild pain (3.92 ± 1.93 and 2.69 ± 2.83, respectively; p = 0.036). The “psychological discomfort” OHIP-14’s domain was the most influenced by the level of pain. Pain severity significantly influenced OHRQoL, in adult patients under treatment with clear aligners. However, high levels of patient satisfaction were reported, regardless of pain duration or severity.
本研究旨在比较矫治器治疗期间疼痛对生活质量和患者满意度的影响。研究邀请了94名正在接受治疗的受试者回答有关疼痛的严重程度和持续时间、其他体征和症状的出现以及对治疗的满意程度等自我报告问题。此外,还采用了 OHIP-14 问卷来评估患者的 OHRQoL。94 名患者(49 名女性和 45 名男性)回答了调查问卷。69.1%的患者(n = 60)报告疼痛持续时间为1-3天。在报告疼痛的患者中(n = 84),42.9% 的患者认为疼痛为轻度,52.4% 的患者认为疼痛为中度。近64%的样本对矫治器的美观度非常满意(60人),49%的样本对总体治疗满意(46人)。OHIP-14平均分为3.36±2.54分。OHRQoL与疼痛严重程度有明显相关性,报告经历过中度疼痛的患者的OHIP-14平均得分明显高于报告经历过轻度疼痛的患者(分别为3.92 ± 1.93和2.69 ± 2.83;P = 0.036)。心理不适 "OHIP-14 领域受疼痛程度的影响最大。在接受透明矫治器治疗的成年患者中,疼痛严重程度对OHRQoL的影响很大。然而,无论疼痛持续时间或严重程度如何,患者的满意度都很高。

External apical root resorption (EARR) is a frequently observed adverse event in patients undergoing fixed appliance therapy. Assessing the patients’ risk during treatment is important, as certain factors are assumed to be associated with an increased likelihood of occurrence. However, their predictive value remains limited, making evidence-based clinical decision-making challenging for orthodontists. To address this issue, the Dutch Association of Orthodontists (NvVO) developed a clinical practice guideline (CPG) for EARR in accordance with the AGREE II instrument (Appraisal of Guidelines for Research and Evaluation II) in 2018. The aim of this study is to get insight into the actual utilization and the practical implementation of the guideline among orthodontists. The hypothesis to be tested was that after its introduction, clinical practice for EARR has changed towards the recommendations in the CPG. To investigate the use of the 2018 clinical practice guidelines for EARR among orthodontists 3 years after its introduction. A questionnaire using a 7-point Likert scale was developed concerning four domains of EARR described in the guideline. The questionnaire was piloted, finalised, and then distributed digitally among Dutch orthodontists. REDCap was used for data collection, starting with an invitation email in June 2021, followed by two reminders. Effect was tested by the Mann–Whitney U test, and the influence of demographic variables was analysed. Questionnaires were sent out to all 275 and completed by 133 (response rate 48%); N = 59 females and N = 73 males were included; 81% had their training in the Netherlands, 89% had ≥ 6 years of work experience, and 89% worked in private orthodontic practice. One hundred thirty orthodontists (98.5%) reported changes in clinical practice. The biggest positive change in clinical behaviour regarding EARR occurred if EARR was diagnosed during treatment. Sex, clinical experience, country of specialist training, and working environment of the respondents did not affect clinical practices regarding EARR. This questionnaire demonstrated that, 3 years after introduction of the guideline, orthodontists improved their self-reported clinical practices to a more standardised management of root resorption. None of the demographic predictors had a significant effect on the results.
外牙根尖吸收(EARR)是接受固定矫治器治疗的患者中经常出现的不良反应。在治疗过程中评估患者的风险非常重要,因为某些因素被认为与发生的可能性增加有关。然而,这些因素的预测价值仍然有限,使得正畸医生在做出循证临床决策时面临挑战。为解决这一问题,荷兰正畸医师协会(NvVO)于2018年根据AGREE II工具(研究与评估指南II)制定了EARR临床实践指南(CPG)。本研究旨在深入了解正畸医生对该指南的实际利用和实际执行情况。要检验的假设是,在该指南推出后,EARR的临床实践已朝着CPG中的建议发生了变化。调查 2018 年 EARR 临床实践指南推出 3 年后,正畸医生对该指南的使用情况。针对指南中描述的 EARR 的四个领域编制了一份采用 7 点李克特量表的调查问卷。问卷经过试用、定稿,然后以数字形式在荷兰正畸医师中分发。数据收集使用了 REDCap,从 2021 年 6 月的一封邀请邮件开始,随后又发出了两封提醒邮件。采用 Mann-Whitney U 检验法检验效果,并分析人口统计学变量的影响。向所有275名正畸医生发送了问卷,其中133人填写了问卷(回复率为48%);其中女性59人,男性73人;81%的正畸医生在荷兰接受过培训,89%的正畸医生拥有≥6年的工作经验,89%的正畸医生在私人正畸诊所工作。130名正畸医生(98.5%)报告了临床实践中的变化。如果在治疗过程中诊断出 EARR,则临床行为对 EARR 的积极改变最大。受访者的性别、临床经验、接受过专业培训的国家和工作环境均不影响有关 EARR 的临床实践。该调查问卷表明,在该指南推出 3 年后,正畸医生自我报告的临床实践有所改善,对牙根吸收的管理更加标准化。人口统计学预测因素均未对结果产生显著影响。

To evaluate the accuracy of a semi-automatic 3D digital setup process in predicting the orthodontic treatment outcome achieved by labial fixed appliances. Twenty-five adult patients (18 to 24 years old) with class I malocclusion and moderate crowding were prospectively enrolled and received treatment on both jaws through the straight-wire technique. Prior to treatment commencement, a semi-automatic digital setup simulating the predicted treatment outcome was performed for each patient through Orthoanalyzer software (3Shape®, Copenhagen, Denmark) to obtain the prediction model. This was compared to the final outcome model through 3D superimposition methods. Metric variables and inspection of color-coded distance maps were used to detect how accurately the digital setup predicts the actual treatment outcome. The mean absolute distances (MAD) between the superimposed dental arches of the predicted and the final models were: 0.77 ± 0.13 mm following superimposition on the palate, 0.52 ± 0.06 mm following superimposition on the maxillary dental arch, and 0.55 ± 0.15 mm following superimposition on the mandibular dental arch. The MAD at the palatal reference area was 0.09 ± 0.04 mm. Visualization of color-coded distance maps indicated that the digital setup accurately predicted the final teeth position in a few cases. Almost half of the cases had posteriorly wider upper and lower dental arches and palatally/lingually positioned or inclined anterior teeth, whereas the rest still showed errors within 2–3 mm, distributed over the entire dental arches with no distinct pattern. The accuracy of semi-automatic prediction of the labial fixed appliance treatment outcome in Class I cases with moderate crowding is not yet sufficient. While average measures showed deviations less than 1 mm, examination of individual color-coded distance maps revealed significant disparities between the simulated and the actual results.
评估半自动三维数字设置过程在预测唇侧固定矫治器矫治效果方面的准确性。25 名患有 I 类错牙合畸形和中度牙齿拥挤的成年患者(18 至 24 岁)被纳入前瞻性研究,并通过直丝技术接受了双颌矫治。治疗开始前,通过 Orthoanalyzer 软件(3Shape®,丹麦哥本哈根)对每位患者进行了预测治疗结果的半自动数字模拟设置,以获得预测模型。通过三维叠加方法将其与最终结果模型进行比较。度量变量和彩色编码距离图检查用于检测数字设置预测实际治疗结果的准确程度。预测模型和最终模型的叠加牙弓之间的平均绝对距离(MAD)分别为叠加到上颚后为 0.77 ± 0.13 毫米,叠加到上颌牙弓后为 0.52 ± 0.06 毫米,叠加到下颌牙弓后为 0.55 ± 0.15 毫米。腭侧参照区的 MAD 为 0.09 ± 0.04 mm。彩色编码距离图的可视化显示,数字设置在少数病例中准确预测了最终的牙齿位置。近一半病例的上下牙弓向后加宽,前牙位于腭/舌侧或倾斜,而其余病例的误差仍在 2-3 毫米以内,分布于整个牙弓,没有明显的规律。对于中度拥挤的 I 类病例,半自动预测唇侧固定矫治器治疗结果的准确性还不够。虽然平均测量结果显示偏差小于 1 毫米,但对单个彩色编码距离图的检查显示,模拟结果与实际结果之间存在显著差异。

Background: There are currently no studies that quantitatively compare the relationship of root resorption to the patient's systemic history or craniofacial and intraoral morphology, especially in relation to possible host factors. Thus, this study aimed to clarify the factors associated with root resorption in retained mandibular second deciduous molars with the congenital absence of second premolars and predict the prognosis of retained mandibular second deciduous molars.

Methods: A cohort of 5547 patients who visited the orthodontic clinic at Tokyo Medical and Dental University Dental Hospital between 2013 and 2022 was screened. Lateral cephalometric radiographs, panoramic radiographs, upper and lower dental models, and orthodontic treatment questionnaires were used as reference materials to apply the inclusion and exclusion criteria. Ultimately, 111 patients were included in the analyses. The patients were divided into two groups based on the root resorption levels of the retained mandibular second deciduous molars. Those with less root resorption were classified under the good condition (GC) group, whereas those with more root resorption were classified under the poor condition (PC) group. Demographic, clinical, and cephalometric parameters were compared between the groups. A multivariate logistic regression model was used to predict the probability of root resorption.

Results: The prevalence of congenitally missing mandibular second premolars with persistent mandibular second deciduous molars was 2.0%. In a total of 111 patients, eighty-three teeth (53.2%) were classified into the GC group, whereas 73 teeth (46.8%) were classified into the PC group. The Frankfort-mandibular plane angle (FMA) [odds ratio (OR): 0.87], Frankfort-mandibular incisor angle (FMIA) (OR: 0.93), overbite (OR: 1.38), adjacent interdental space (OR: 1.46), distance from occlusal plane (OR: 0.80), and caries treatment (OR: 7.05) were significantly associated with the root resorption of the retained mandibular second deciduous molars.

Conclusions: Our findings suggest that skeletal morphology, oral morphological patterns, and history contribute to root resorption in retained mandibular second deciduous teeth with congenital absence of subsequent permanent teeth.

背景:目前还没有研究定量比较牙根吸收与患者的系统病史或颅面和口腔内形态的关系,尤其是与可能的宿主因素的关系。因此,本研究旨在明确先天性无第二前磨牙的下颌第二乳磨牙滞留患者牙根吸收的相关因素,并预测下颌第二乳磨牙滞留的预后:筛选了2013年至2022年间在东京医科齿科大学齿科医院正畸门诊就诊的5547名患者。以头侧X光片、全景X光片、上下牙齿模型和正畸治疗问卷作为参考资料,应用纳入和排除标准。最终,111 名患者被纳入分析。根据滞留的下颌第二乳磨牙的牙根吸收程度将患者分为两组。牙根吸收较少的患者被分为情况良好(GC)组,而牙根吸收较多的患者被分为情况较差(PC)组。对各组的人口统计学、临床和头型测量参数进行了比较。采用多变量逻辑回归模型预测牙根吸收的概率:先天性下颌第二前磨牙缺失伴下颌第二乳磨牙持续存在的发病率为 2.0%。在111名患者中,83颗牙齿(53.2%)被归为GC组,73颗牙齿(46.8%)被归为PC组。法兰克福-下颌平面角(FMA)[几率比(OR):0.87]、法兰克福-下颌切牙角(FMIA)(OR:0.93)、咬合过度(OR:1.38)、邻牙间隙(OR:1.46)、咬合平面距离(OR:0.80)和龋病治疗(OR:7.05)与滞留下颌第二乳磨牙的牙根吸收显著相关:我们的研究结果表明,骨骼形态、口腔形态模式和病史是导致下颌第二乳磨牙滞留并伴有后继恒牙先天缺失的牙根吸收的原因。
