Objectives: To quantify the amount of residual monomer released from orthodontic adhesives used in the indirect bonding technique and compare it to a direct bonding composite resin.

Materials and methods: Five hundred stainless steel orthodontic brackets were bonded on bovine incisors using five groups of bonding resins: Transbond XT (TXT), Transbond Supreme LV (SLV), Sondhi Rapid-Set (SRS), Transbond IDB (IDB), and Custom I.Q. (CIQ). Liquid samples were gathered on the first, seventh, 21st, and 35th days. Residual monomer release was measured from the liquid samples with a liquid chromatography device. In addition, the amount and shape of the adhesive between the tooth surface and the bracket base was evaluated using obtained electron microscopy images. The data were analyzed using analysis of variance, and a Tukey post-hoc test was applied.

Results: Hydroxyethylmethacrylate and bisphenol A-glycidyl methacrylate monomers were released by all study groups. Urethane-dimethacrylate was released from the TXT, SLV, IDB, and CIQ groups. Triethylene glycol dimethacrylate was released from TXT, SLV, IDB, and SRS groups. The amount of total monomer release was higher in chemically cured adhesives than in light-cured adhesives. Among the chemically cured adhesives, premix adhesives had the highest amount of total monomer release. The light-cured adhesives had less thickness.

Conclusions: Light-curing adhesives have significantly less monomer release than chemically polymerized adhesives.

目的:量化间接粘接技术中使用的正畸粘合剂释放的残余单体量,并将其与直接粘接复合树脂进行比较。材料和方法:使用Transbond XT(TXT)、Transbond Supreme LV(SLV)、Sondhi Rapid Set(SRS)、Transbond IDB(IDB)和Custom I.Q。在第1天、第7天、第21天和第35天采集液体样本。用液相色谱装置测量液体样品中残留单体的释放。此外,使用获得的电子显微镜图像来评估牙齿表面和托槽基座之间的粘合剂的量和形状。使用方差分析对数据进行分析,并应用Tukey事后检验。结果:所有研究组均释放出甲基丙烯酸羟乙酯和甲基丙烯酸双酚A缩水甘油酯单体。二甲基丙烯酸氨基甲酸乙酯从TXT、SLV、IDB和CIQ组中释放。TXT、SLV、IDB和SRS组释放出三甘醇二甲基丙烯酸酯。化学固化的粘合剂中的总单体释放量高于光固化的粘合剂。在化学固化的胶粘剂中,预混胶粘剂的总单体释放量最高。光固化的粘合剂具有较小的厚度。结论:光固化胶粘剂的单体释放量明显低于化学聚合胶粘剂。

Objectives: To evaluate the outcome of treating deep overbite (OB) using anterior bite elevators concurrently with a pre-adjusted edgewise appliance.

Materials and methods: The Case Western Reserve University (CWRU) cephalometric analysis was used to isolate tipping movement of upper (TUI) and lower incisors (TLI), bodily tooth movement of upper (BUI), and lower incisors (BLI), as well as vertical skeletal changes in the anterior region of the maxilla (MXSK) and mandible (MNSK). Thirty treated subjects were examined at pretreatment (T1) and posttreatment (T2) and compared to an untreated control group matched on age, sex, and Angle malocclusion from the Bolton Brush Growth Study Collection (CWRU, Cleveland, Ohio).

Results: Overbite (OB) in the treated group was decreased significantly (P < .001) (-5.6 mm) compared to controls. Statistically significant (P < .001) changes were found for BUI (-0.7 mm), TUI (0.9 mm), TLI (-1.4 mm), BLI (-1.1 mm), and MNSK (-1.6 mm). Most of the overbite correction was in the lower arch and included tipping and intrusion of the lower incisors along with an increase in lower vertical facial height.

Conclusions: Deep OB correction was achieved efficiently using anterior bite elevators with pre-adjusted edgewise appliance. Correction using bite turbos would be a treatment option for individuals presenting with decreased lower facial height and deep bite.

目的:评价使用前部咬合提升器和预先调整的扁牙矫治器治疗深覆牙(OB)的疗效。材料和方法:凯斯西储大学(CWRU)的头影测量分析用于分离上切牙(TUI)和下切牙(TLI)的倾翻运动、上切牙和下切齿的体牙运动以及上颌骨前部(MXSK)和下颌骨(MNSK)的垂直骨骼变化。30名接受治疗的受试者在治疗前(T1)和治疗后(T2)接受了检查,并与Bolton Brush Growth Study Collection(CWRU,Cleveland,Ohio)中年龄、性别和安氏错牙合角度匹配的未接受治疗的对照组进行了比较。BUI(-0.7 mm)、TUI(0.9 mm)、TLI(-1.4 mm)、BLI(-1.1 mm)和MNSK(-1.6 mm)的变化具有统计学意义(P<.001)。大多数覆牙矫正发生在下牙弓,包括下切牙倾斜和侵入,以及面部垂直高度的增加。结论:使用前牙咬合提升器和预调整的扁立矫治器可以有效地实现深度OB矫正。对于面部高度降低和被深深咬伤的患者,使用大菱鲆进行矫正是一种治疗选择。

Objectives: To investigate the association between the width of keratinized gingiva (WKG), gingival phenotype (GP), and gingival thickness (GT) with craniofacial morphology in sagittal and vertical dimensions.

Materials and methods: WKG, GP, and GT of mandibular anterior teeth in 177 preorthodontic patients (mean age 18.38 ± 5.16 years) were assessed clinically using a periodontal probe, a Colorvue Biotype Probe, and ultrasound by a single examiner. Patients were grouped into skeletal Class I, II, and III and hyperdivergent, normodivergent, and hypodivergent based on ANB and SN-MP angles. Mandibular incisor inclination (L1-NB) was also measured. Clinical and cephalometric measurements were repeated to assess inter- and intraexaminer reproducibility.

Results: A significant association was found between thin GP and skeletal Classes I and III for the left mandibular central incisor (MCI; P = .0183). In skeletal Class III patients, L1-NB angle demonstrated a decreasing trend as phenotype thickness decreased. A significant association was found between thin phenotype and normodivergent and hypodivergent groups for MCIs (left: P = .0009, right: P = .00253). No significant association between WKG or GT and craniofacial morphology was found.

Conclusions: Thin GP is associated with skeletal Class I and III for the left MCI. Thin GP is associated with hypodivergent and normodivergent skeletal patterns for the MCIs. There was no association between WKG and GT and craniofacial morphology in both skeletal and vertical dimensions. Dental compensations that exist due to different craniofacial morphology may influence the GP.

目的:研究角化牙龈宽度(WKG)、牙龈表型(GP)和牙龈厚度(GT)与矢状面和垂直面颅面形态之间的关系。材料和方法:177例牙周前患者(平均年龄18.38±5.16岁)的下颌前牙WKG、GP和GT由一名检查者使用牙周探针、Colorvue生物型探针和超声进行临床评估。根据ANB和SN-MP角度,将患者分为骨骼I、II和III级以及高分化、常分化和低分化。还测量了下颌切牙倾斜度(L1-NB)。重复进行临床和头影测量,以评估检查者之间和检查者内部的再现性。结果:左下颌中切牙(MCI)的薄GP与骨骼类别I和III之间存在显著关联;P=.0183。在骨骼类别III患者中,随着表型厚度的降低,L1-NB角呈下降趋势。薄表型与MCIs的正常分化组和低剂量组之间存在显著关联(左:P=.0009,右:P=.00253)。WKG或GT与颅面形态之间没有发现显著关联。结论:薄GP与左侧MCI的骨骼I级和III级相关。薄GP与MCIs的低剂量和正常分化的骨骼模式有关。在骨骼和垂直维度上,WKG和GT与颅面形态之间没有关联。由于不同的颅面形态而存在的牙齿补偿可能会影响GP。

Objectives: To evaluate the efficacy of chewing gum on the intensity of pain in patients undergoing orthodontic treatment.

Materials and methods: A search strategy that included both a manual search and a search of electronic databases was implemented; the electronic databases included PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), ScienceDirect, Scopus, and EBSCO. Only randomized controlled trials were included in this study. All of the studies were assessed independently and in duplicate in accordance with the exclusion and inclusion criteria. The Cochrane risk of bias tool was used to evaluate the risk of bias within the included studies, and the GRADE approach was used to evaluate the certainty of evidence.

Results: Sixteen RCTs were included in the final analysis. The meta-analysis revealed that chewing gum significantly reduced pain intensity in comparison to pharmacologic agents (mean difference [MD] -0.50 [95% confidence interval {CI} -0.90 to -0.10], P = .01). When compared with a placebo, chewing gum significantly reduced pain intensity (MD -0.60 [95% CI -1.06 to -0.13], P = .01), while bite wafer and chewing gum groups had the same levels of reduction in pain intensity (MD -0.15 [95% CI -0.56 to 0.26], P = .48).

Conclusions: In patients undergoing fixed orthodontic treatment, chewing gum was significantly more effective than both pharmacologic agents and placebo in reducing orthodontic pain 24 hours after the initial placement of the archwire.

目的:评价口香糖对正畸治疗患者疼痛强度的影响。材料和方法:实施了一项搜索战略,包括手动搜索和电子数据库搜索;电子数据库包括PubMed、Cochrane对照试验注册中心(Central)、ScienceDirect、Scopus和EBSCO。本研究仅包括随机对照试验。所有研究均根据排除和纳入标准进行独立评估,一式两份。Cochrane偏倚风险工具用于评估纳入研究中的偏倚风险,GRADE方法用于评估证据的确定性。结果:16项随机对照试验纳入最终分析。荟萃分析显示,与药物相比,口香糖显著降低了疼痛强度(平均差异[MD]-0.50[95%置信区间{CI}-0.90至-0.10],P=0.01)。与安慰剂相比,口香糖明显降低了疼痛程度(MD-0.60[95%可信区间-1.06至-0.13],P=.01),而咬片组和口香糖组的疼痛强度降低程度相同(MD-0.15[95%CI-0.56至0.26],P=.48)。结论:在接受固定正畸治疗的患者中,在最初放置弓丝24小时后,口香糖在减轻正畸疼痛方面明显比药物和安慰剂更有效。

The stomatognathic structures act as a complex and integrated system, thereby accomplishing several essential functions of the body. Aside from participating in food digestion, they are key for respiration and swallowing and play a central role in social interaction and stress management. The lifeworks of Robert M. Ricketts (1920-2003), an American orthodontist, and Rudolf Slavicek (1928-2022), an Austrian prosthodontist, were centered on this understanding. Both were educated in the time of gnathology, functional dentistry, and cephalometry and were ready to challenge conventional knowledge and traditions, leading toward innovation. As untiring clinicians, researchers, and mentors, they were fully invested in the study of the stomatognathic system, considering its morphology, dynamics, growth patterns, evolution, and interactions with the body and mind. Based on their extensive knowledge of the masticatory system, they advanced dentistry both with theoretical notions and by implementing new diagnostic and therapeutic concepts, thus reinforcing the idea of dentistry as a medical discipline requiring interdisciplinary effort. Their heritage is represented by numerous publications, discoveries, and inventions that inspire the dental community to follow their exemplary approach to the individualized care of patients. Their knowledge and passion are further passed on through their students. As part of their legacy, they prepared the ground for new research aimed at fostering advancements in occlusion medicine, hence supporting education in oral health.

口腔颌结构是一个复杂而完整的系统,从而实现身体的几个基本功能。除了参与食物消化,它们还是呼吸和吞咽的关键,在社交和压力管理中发挥着核心作用。美国口腔正畸学家Robert M.Ricketts(1920-2003)和奥地利口腔正畸学家Rudolf Slavicek(1928-2022)的毕生著作都围绕着这一理解展开。两人都接受过口腔学、功能牙科和头影测量学的教育,并准备挑战传统知识和传统,走向创新。作为坚持不懈的临床医生、研究人员和导师,他们充分投入到口腔颌面系统的研究中,考虑到其形态、动力学、生长模式、进化以及与身心的相互作用。基于他们对咀嚼系统的广泛了解,他们通过理论概念和实施新的诊断和治疗概念来推进牙科,从而强化了牙科作为一门需要跨学科努力的医学学科的理念。他们的遗产体现在许多出版物、发现和发明中,这些出版物、发现、发明激励牙科界遵循他们的模范方法对患者进行个性化护理。他们的知识和热情在学生身上得到进一步的传递。作为他们遗产的一部分,他们为旨在促进咬合医学进步的新研究奠定了基础,从而支持口腔健康教育。

Objectives: To investigate aligner treatment protocols among orthodontists in the United States and Canada and assess the factors influencing clinician choices in aligner systems, treatment protocols, and targeted malocclusions for aligners.

Materials and methods: A validated online questionnaire was developed specifically for this research and consisted of three sections. Section 1 evaluated demographics and experience with aligners. Section 2 assessed patient selection and demands and clinician confidence in treating various malocclusions with aligners. Section 3 evaluated treatment protocols used by clinicians. The American Association of Orthodontists Partners in Research Program distributed the survey via e-mail to active members in the United States and Canada.

Results: A total of 160 providers completed the survey. Aligners were used by 65.00% of respondents, with the Invisalign system the most popular (81.25%). Aligners were mostly used for adults (97.50%). Tipping was ranked as the easiest movement (1.79 ± 1.35). Extrusion (4.34 ± 1.53) and root movement (4.31 ± 1.27) were ranked as the most difficult. Most were confident treating mild (98.8%) and moderate (82.5%) crowded cases, spacing (96.9%), and anterior crossbite (85%). Of the providers, 58.12% recommended aligners to be changed weekly. Respondents who were confident addressing some of the severe malocclusions were more likely to use Invisalign.

Conclusions: Invisalign is the most popular aligner system, and clinicians seem to be confident using it. Providers are aware of the pitfalls of aligners; they find it challenging to perform root movement and extrusion, and they seem confident treating mild to moderate malocclusions. They avoid complex cases with impactions and severe skeletal problems.

Objectives: To compare skeletal and dentoalveolar changes of miniscrew-assisted rapid palatal expansion (MARPE) according to the length of the miniscrews.

Materials and methods: This two-arm parallel-randomized controlled trial included 32 adult patients aged 19-35 years who received orthodontic treatment with MARPE. Patients were allocated to two groups, group long (L) and short (S), through block randomization according to the length of the miniscrews installed in MARPE. Cone-beam computed tomography was performed before expansion and after removal of the MARPE; superimposition of the images was conducted. The primary outcome included the amount of bone expansion and the change in the inclination of the anchorage teeth. The secondary outcome included the success rate of midpalatal suture opening and stability of the miniscrews. Blinding was performed during outcome assessment.

Results: The final sample comprised 31 patients. There was no significant difference in patient characteristics between group L (n = 16) and group S (n = 15). The change in the width of the processus zygomaticus (P = .010) and ectocanine (P = .001) was significantly higher in group L. A significantly higher success rate of the posterior miniscrews was seen in group L (P = .024). There was no statistically significant difference in the success rate of suture separation or change in tooth inclination. Notable complications were not reported.

Conclusions: MARPE with longer miniscrews can increase the amount of expansion of the maxillary basal bone and canine alveolar bone. Although it also aided in miniscrew stability, it did not guarantee successful midpalatal suture separation.

目的:比较微钉辅助快速腭扩张术(MARPE)在不同长度微钉辅助快速腭扩张术中骨骼和牙槽牙的变化。材料和方法:本研究纳入32例年龄19-35岁接受MARPE正畸治疗的成人患者。根据MARPE中安装的微型螺钉的长度,通过分组随机将患者分为长组(L)和短组(S)。在扩张前和切除MARPE后分别进行锥束计算机断层扫描;对图像进行叠加。主要结果包括骨扩张量和支抗牙的倾斜度变化。次要结果包括中腭缝线打开的成功率和微型螺钉的稳定性。结果评估时采用盲法。结果:最终样本包括31例患者。L组(n = 16)与S组(n = 15)患者特征无显著差异。L组颧突宽度变化(P = 0.010)和外突宽度变化(P = 0.001)显著高于L组,L组后侧微型螺钉成功率显著高于L组(P = 0.024)。两组间缝线分离成功率及牙倾角变化无统计学差异。未见明显并发症。结论:长钉MARPE可以增加上颌基骨和犬牙槽骨的扩张量。虽然它也有助于微钉的稳定性,但它并不能保证成功的中腭缝线分离。

Objectives: To evaluate the utility and efficiency of four voice-activated, artificial intelligence-based virtual assistants (Alexa, Google Assistant, Siri, and Cortana) in addressing commonly asked patient questions in orthodontic offices.

Materials and methods: Two orthodontists, an orthodontic resident, an oral and maxillofacial radiologist, and a dental student used a standardized list of 12 questions to query and evaluate the four most common commercial virtual assistant devices. A modified Likert scale was used to evaluate their performance.

Results: Google Assistant had the lowest (best) mean score, followed by Siri, Alexa, and Cortana. The score of Google Assistant was significantly lower than Alexa and Cortana. There was significant variablity in virtual assistant response scores among the evaluators, with the exception of Amazon Alexa. Lower scores indicated superior efficiency and utility.

Conclusions: The common commercially available virtual assistants tested in this study showed significant differences in how they responded to users. There were also significant differences in their performance when responding to common orthodontic queries. An intelligent virtual assistant with evidence-based responses specifically curated for orthodontics may be a good solution to address this issue. The investigators in this study agreed that such a device would provide value to patients and clinicians.

目的:评估四种声控、基于人工智能的虚拟助手(Alexa、Google Assistant、Siri和Cortana)在解决正畸诊所患者常见问题方面的效用和效率。材料和方法:两名正畸医生,一名正畸住院医师,一名口腔颌面放射科医生和一名牙科学生使用标准化的12个问题列表来查询和评估四种最常见的商用虚拟助手设备。采用改良李克特量表对其进行评价。结果:谷歌助手的平均得分最低(最好),其次是Siri、Alexa和Cortana。Google Assistant的得分明显低于Alexa和Cortana。除了亚马逊Alexa之外,评估者在虚拟助手的反应得分上存在显著差异。分数越低表明效率和效用越好。结论:在本研究中测试的常见商用虚拟助手在如何响应用户方面显示出显着差异。在回答常见的正畸问题时,他们的表现也有显著差异。一个专门为正畸治疗设计的基于证据的智能虚拟助手可能是解决这一问题的一个很好的解决方案。这项研究的研究人员一致认为,这种设备将为患者和临床医生提供价值。

Objectives: To evaluate the content and quality of information about orthodontic pain on YouTube.

Materials and methods: YouTube was searched using the keywords "orthodontic pain" and "brace pain." A total of 65 videos were chosen for the final analysis. Videos were classified into high- and low-content groups using an eight-point scoring system and reviewed according to selected orthodontic pain-related topics. Video quality was rated by the Video Information and Quality Index (VIQI) and Global Quality Scale (GQS). Statistical data analysis was performed using SPSS 28.0 software, Mann-Whitney U-tests, χ2 tests, and Spearman correlation coefficients.

Results: Most YouTube videos related to orthodontic pain were low content (86.2%), and a few were high content (13.8%). Pharmacological pain relief was the most prevalent topic (50.8%), followed by duration of pain (32.3%) and influence of pain on patient quality of life (29.2%). The least-mentioned topic was possible location of pain (7.7%). Most of the videos were uploaded by laypeople (64.6%). Videos uploaded by dental professionals had significantly higher means of GQS scores (P = .035), flow of information (P < .001), information quality (P = .008), and total VIQI (P < .001). Compared with low-content, high-content videos had a higher mean of flow of information (P = .037). There was a weak correlation between total content and GQS scores and a strong correlation between GQS and VIQI scores (r = 0.740; P < .01).

Conclusions: Overall, YouTube was found to be an inadequate source of information on orthodontic pain.

目的:评价YouTube上正畸疼痛相关信息的内容和质量。材料和方法:在YouTube上搜索关键词“正畸疼痛”和“支具疼痛”。共有65个视频被选中进行最终分析。使用8分评分系统将视频分为高内容组和低内容组,并根据选择的正畸疼痛相关主题进行审查。视频质量由视频信息和质量指数(VIQI)和全球质量量表(GQS)评定。统计资料采用SPSS 28.0软件、Mann-Whitney u检验、χ2检验和Spearman相关系数进行分析。结果:YouTube上与正畸疼痛相关的视频内容以低内容为主(86.2%),高内容占少数(13.8%)。药物缓解疼痛是最普遍的话题(50.8%),其次是疼痛持续时间(32.3%)和疼痛对患者生活质量的影响(29.2%)。最少被提及的话题是疼痛的可能部位(7.7%)。大部分视频是由外行人上传的(64.6%)。牙科专业人员上传的视频在GQS得分(P = 0.035)、信息流(P < 0.001)、信息质量(P = 0.008)和总VIQI (P < 0.001)方面均有显著提高。与低内容视频相比,高内容视频的平均信息流更高(P = 0.037)。总含量与GQS评分呈弱相关,与VIQI评分呈强相关(r = 0.740;P < 0.01)。结论:总的来说,YouTube是一个不充分的正畸疼痛信息来源。

Objectives: To investigate hyoid bone position and airway volume in subjects with adenoid hypertrophy, tonsillar hypertrophy, and adenotonsillar hypertrophy compared to subjects with nonobstructive adenoids or tonsils and to assess the correlation between hyoid bone and airway parameters.

Materials and methods: A total of 121 subjects were grouped based on adenoid or tonsillar hypertrophy into four groups, as follows: (1) control group (C-group), (2) adenoid hypertrophy group (AH-group), (3) adenotonsillar hypertrophy group (ATH-group), and (4) tonsillar hypertrophy group (TH-group). Hyoid bone position and airway volumes were measured. The Kruskal-Wallis test was used for intergroup comparison, followed by pairwise comparison using the Mann-Whitney U-test. Bivariate correlation was conducted using Spearman correlation coefficients. Multiple linear regression was performed to create a model for airway volume based on hyoid bone predictive variables.

Results: No significant difference was found between subjects with isolated adenoid or tonsillar hypertrophy compared to the C-group. However, the ATH-group exhibited a significantly decreased hyoid bone vertical distance (HV), total airway volume (TA volume), and retroglossal airway volume (RG volume) compared to the C-group. HV and age had a high potential in terms of explaining the RG volume, whereas the TA volume and retropalatal airway volume (RP volume) models were not as successful as the RG volume counterpart.

Conclusions: Subjects in ATH-group were characterized by an elevated hyoid bone position and constricted TA volume and RG volume compared to those in the C-group. HV and age were predictor variables that best explained retroglossal airway volume.

目的:研究与非阻塞性腺样体或扁桃体患者相比,腺样体肥大、扁桃体肥大和腺扁桃体肥大患者舌骨位置和气道体积,并评估舌骨与气道参数的相关性。材料与方法:121例受试者根据腺样体或扁桃体肥大情况分为4组:(1)对照组(c组)、(2)腺样体肥大组(ah组)、(3)腺扁桃体肥大组(ath组)、(4)扁桃体肥大组(th组)。测量舌骨位置和气道容积。组间比较采用Kruskal-Wallis检验,两两比较采用Mann-Whitney u检验。采用Spearman相关系数进行双变量相关。采用多元线性回归建立基于舌骨预测变量的气道容积模型。结果:与c组相比,分离性腺样体或扁桃体肥大的受试者之间无显著差异。然而,与c组相比,ath组表现出舌骨垂直距离(HV),气道总容积(TA容积)和舌后气道容积(RG容积)明显减小。HV和年龄在解释RG体积方面具有很高的潜力,而TA体积和腭后气道体积(RP体积)模型不如RG体积模型成功。结论:与c组相比,ath组患者舌骨位置升高,TA体积和RG体积缩小。HV和年龄是最能解释舌后气道容积的预测变量。
