Purpose: Genetic variants of AMELX gene can affect the protein content, organization of enamel prisms, microstructure and microhardness of the enamel, thus altering the caries susceptibility. The present study aims to assess the association between polymorphisms rs17878486, rs5934997, and rs5933871 of AMELX gene and Early Childhood Caries (ECC).

Materials and methods: This case-control study was conducted on 200 participants, aged 3-6 years, with 100 controls and 100 children with ECC. A questionnaire was used to collect demographic data, birth-weight, type of delivery, oral hygiene practices, feeding history and 24-h diet diary. DNA was isolated from blood and subjected to PCR followed by Sanger sequencing.

Results: The CC genotype of rs17878486 showed an OR of 1.93 (0.34-10.81; P = 0.73). In a recessive model, the CC genotype of rs17878486 reported an OR of 2.04 (0.36-11.40; P = 0.68); rs5593871 reported an OR of 1.00 (0.31-3.21). Statistically significant differences (P ≤ 0.05) between genotype and allele frequencies of rs17878486, rs5934997, and rs5933871 were not observed between children with ECC and the controls.

Conclusion: Polymorphisms of AMELX gene did not show a significant association with ECC in this population. However, documentation of genetic data in a global context of ECC may be essential for the future.

目的:AMELX基因的遗传变异可影响釉质的蛋白质含量、釉棱组织、微结构和微硬度,从而改变龋病的易感性。本研究旨在评估 AMELX 基因多态性 rs17878486、rs5934997 和 rs5933871 与儿童早期龋齿(ECC)之间的关联:这项病例对照研究以 200 名 3-6 岁的参与者为对象,其中包括 100 名对照组和 100 名 ECC 患儿。调查问卷用于收集人口统计学数据、出生体重、分娩类型、口腔卫生习惯、喂养史和 24 小时饮食日记。从血液中分离出DNA,然后进行PCR和Sanger测序:rs17878486的CC基因型的OR值为1.93(0.34-10.81;P = 0.73)。在隐性模型中,rs178486的CC基因型的OR值为2.04(0.36-11.40;P = 0.68);rs5593871的OR值为1.00(0.31-3.21)。rs17878486、rs5934997和rs5933871的基因型和等位基因频率在ECC患儿和对照组之间没有统计学意义上的差异(P≤0.05):结论:在这一人群中,AMELX 基因的多态性与 ECC 没有明显关联。结论:在这一人群中,AMELX 基因的多态性并未显示出与 ECC 的显著关联。然而,在未来,记录 ECC 全球背景下的遗传数据可能是至关重要的。

Purpose: The study aimed to evaluate temporary fillings using Biodentine™ in asymptomatic deep carious lesions after 12, 24, and 36 months in school children from the remote village of Kerung, Nepal.

Methods: From November 2018 to November 2019, 91 temporary fillings were placed using Biodentine™ (a hydraulic calcium silicate cement) in permanent molars with deep carious lesions of schoolchildren in the remote district of Kerung, Nepal. These restorations were performed after selective caries removal in a non-dental setting with hand instruments and cotton roll isolation, as electric motors and saliva ejection systems were unavailable. In total, 78 single-surface and 13 multi-surface fillings were placed. Clinical and radiographic follow-up periods encompassed 12, 21, and 33 months, respectively.

Results: After 12 months, all single-surface fillings (100%) survived, whilst all multi-surface fillings were partially or entirely lost. The survival rate of single-surface restorations after 21 and 33 months was 67.6% and 50%, respectively. Radiographically, no pathology was observed.

Conclusion: This study showed that Biodentine could be used in deep carious lesions as a temporary filling in single-surface lesions for at least up to 1 year and in a substantial number of cases for up to 21 and 33 months.

目的:该研究旨在评估使用 Biodentine™ 对尼泊尔 Kerung 偏远村庄的学龄儿童无症状深龋病变进行临时填充 12、24 和 36 个月后的效果:从 2018 年 11 月到 2019 年 11 月,使用 Biodentine™(一种水性硅酸钙水泥)对尼泊尔 Kerung 偏远地区学龄儿童有深龋病变的恒磨牙进行了 91 次临时补牙。由于没有电动马达和唾液喷射系统,这些修复体是在非牙科环境下使用手工器械和棉卷隔离进行选择性龋齿去除后进行的。总共进行了 78 次单面补牙和 13 次多面补牙。临床和放射学随访期分别为 12 个月、21 个月和 33 个月:12 个月后,所有单面填充物(100%)均存活,而所有多面填充物均部分或全部脱落。21 个月和 33 个月后,单面修复体的存活率分别为 67.6% 和 50%。从影像学角度看,未发现任何病变:这项研究表明,Biodentine 可用于深龋病变的单面临时充填,使用时间至少可达 1 年,相当多的病例可使用 21 个月和 33 个月。

Purpose: To evaluate the volumetric changes of two recently introduced paediatric rotary file systems in comparison with conventional hand file systems in primary maxillary canines using an ultra-high-resolution nano-computed tomography.

Methods: This in vitro study was performed in extracted primary maxillary canines based on certain inclusion and exclusion criteria. Samples were prepared, and working length was determined after the pre-operative scan using a high-resolution nano-CT device (SkyScan 2214, Bruker, Kontich, Belgium). A single well-experienced paediatric dentist prepared the canals using three file systems: Kedo-S plus, Kedo-SG blue and hand K-files. All samples were subjected to post-operative scans performed similar to pre-operative scans. Image reconstruction was performed with NRecon software for 3D volumetric visualisation and analysis of the root canals.

Results: Kedo-SG blue file systems had the highest mean difference in the canal volume (4.05%). Hand K-files had the least difference at (3.71%) of canal volume. Kedo-S plus file system had a moderate mean canal volume difference (3.82%) which is closer to hand K-files. Intergroup comparison between the three groups showed that the mean difference in canal volume was statistically significant between all three file systems (p = 0.000).

Conclusion: Within the limitations of the current study, rotary file systems produced a significant enlargement of canals as compared to hand files. Kedo-SG blue created a uniform preparation of the canal cervico-apically. Kedo-S plus files were prepared more coronally with minimal preparation apically as close to the preparation of hand files.

Oral findings in paediatric patients with severe heart, liver, and kidney failure prior to organ transplantation. 器官移植前严重心、肝、肾功能衰竭儿科患者的口腔检查结果。
IF 2.2 Q2 DENTISTRY, ORAL SURGERY & MEDICINE Pub Date : 2024-04-01 Epub Date: 2024-03-14 DOI: 10.1007/s40368-024-00879-6

Purpose: Organ transplantation is an effective treatment for children with severe heart, liver, and kidney diseases. These patient groups may have more oral and dental diseases than healthy controls. It is important to eliminate oral infection foci before transplantation and to maintain good oral health to avoid potential post-transplant complications. The aim of this study was to describe and compare oral health in Finnish paediatric heart, liver, and kidney transplant recipients prior to organ transplantation.

Methods: Eighty-six children who received a heart (n = 21), liver (n = 19), or kidney (n = 46) transplant in Finland during the years 2014-2018 were included in this study. The inclusion criterion was a pre-transplantation oral examination. Oral hygiene, enamel anomalies, and the number of decayed, missing, and filled teeth (dmft/DMFT) were analyzed retrospectively from medical and dental records and compared between the three patient groups.

Results: Children with liver (p = 0.043) or heart (p = 0.047) disease had higher combined primary and permanent dentition dmft/DMFT scores compared to children with kidney disease. A higher combined dmft/DMFT score was associated with poor oral hygiene (p = 0.005). No significant differences in oral hygiene between the patient groups were found. Furthermore, all patient groups had a high prevalence of developmental dental defects.

Conclusion: Children with liver or heart disease seem to have a higher combined dmft/DMFT score, indicating a higher prevalence of caries compared to children with kidney disease. Prevention of dental caries, along with promoting a good oral hygiene routine and regular check-ups, is suggested in these patient groups.

目的:对于患有严重心脏、肝脏和肾脏疾病的儿童来说,器官移植是一种有效的治疗方法。与健康对照组相比,这些患者群体可能患有更多的口腔和牙科疾病。在移植前消除口腔感染病灶并保持良好的口腔健康以避免移植后可能出现的并发症非常重要。本研究旨在描述和比较芬兰儿科心脏、肝脏和肾脏移植受者在器官移植前的口腔健康状况:本研究纳入了 2014-2018 年间在芬兰接受心脏(21 例)、肝脏(19 例)或肾脏(46 例)移植的 86 名儿童。纳入标准为移植前口腔检查。研究人员根据医疗和牙科记录对口腔卫生、牙釉质异常以及蛀牙、缺失牙和补牙数量(dmft/DMFT)进行了回顾性分析,并对三组患者进行了比较:结果:与患有肾病的儿童相比,患有肝病(p = 0.043)或心脏病(p = 0.047)的儿童原牙和恒牙的dmft/DMFT综合评分更高。较高的dmft/DMFT综合评分与口腔卫生不良有关(p = 0.005)。在口腔卫生方面,各患者组之间没有发现明显差异。此外,所有患者组的牙齿发育缺陷发生率都很高:结论:与患有肾病的儿童相比,患有肝病或心脏病的儿童的 dmft/DMFT 综合评分似乎更高,这表明龋齿患病率更高。建议这些患者群体在预防龋齿的同时,还应促进良好的口腔卫生习惯和定期检查。

The effect of xylitol chewing gums and candies on caries occurrence in children: a systematic review with special reference to caries level at study baseline. 木糖醇口香糖和糖果对儿童龋齿发生率的影响:系统综述,特别参考研究基线时的龋齿水平。
IF 2.2 Q2 DENTISTRY, ORAL SURGERY & MEDICINE Pub Date : 2024-04-01 Epub Date: 2024-03-02 DOI: 10.1007/s40368-024-00875-w

Purpose: A systematic review of published data was carried out to assess the caries-preventive effects of xylitol chewing gums and candies in children.

Methods: Electronic and hand searches were performed to find clinical studies on the effects of xylitol chewing gums and candies on dental caries in children (≤ 18 years). Prospective randomised or controlled clinical trials published before 2023 were included in the review.

Results: The initial search identified 365 titles to be evaluated. After applying inclusion and exclusion criteria, 15 articles with either fair or low quality were reviewed. Nine articles studied chewing gums, five candies, and one both of them. In the ten evaluated xylitol chewing gum studies xylitol consumption significantly reduced caries occurrence when compared with no treatment or a placebo polyol gum. The effect was clinically significant in studies with high or moderate caries level at study baseline. The results also suggested that the caries-reducing effect of xylitol gums may differ from sorbitol/polyol gums. In five of the six heterogenous xylitol candy studies, no caries-reducing effect was found independent of caries level. In addition to caries level, also the daily xylitol dose was a confounding factor.

Conclusion: The present findings suggest that the caries-reducing effect of adding xylitol chewing gum to the daily diet has been well demonstrated in children and adolescents with high or moderate caries level at study baseline. Xylitol gum use could benefit subjects with active incipient caries lesions on smooth tooth surfaces.

目的:对已发表的数据进行系统综述,以评估木糖醇口香糖和糖果对儿童龋齿的预防效果:方法:通过电子和手工检索,查找有关木糖醇口香糖和糖果对儿童(18 岁以下)龋齿影响的临床研究。2023年之前发表的前瞻性随机或对照临床试验被纳入审查范围:初步检索确定了 365 篇待评估的论文。在采用纳入和排除标准后,对15篇质量一般或较低的文章进行了审查。其中九篇研究了口香糖,五篇研究了糖果,一篇研究了两者。在所评估的 10 项木糖醇口香糖研究中,与不进行任何治疗或服用安慰剂多元醇口香糖相比,服用木糖醇能显著减少龋齿的发生。在基线龋齿水平较高或中等的研究中,木糖醇的效果具有临床意义。研究结果还表明,木糖醇口香糖的防龋效果可能不同于山梨醇/多元醇口香糖。在六项异质木糖醇糖果研究中,有五项研究发现,木糖醇糖果的降龋效果与龋齿水平无关。除龋齿水平外,木糖醇的日剂量也是一个干扰因素:本研究结果表明,在日常饮食中添加木糖醇口香糖对研究基线龋齿水平较高或中等的儿童和青少年的防龋效果已得到充分证明。使用木糖醇口香糖对牙齿表面光滑、龋齿初期活跃的受试者有益。

Introduction: A former study on orthopantomograms from young children with abnormal dental development (not canine ectopia) demonstrated that the tooth bud of the mandibular canine, compared to a stable longitudinal canine axis, could be located normally, anteriorly or posteriorly, with close relation to the first premolar.

Aim: The aim of the present study is to analyse on orthopantomograms if the canine axis can demonstrate where the ectopic mandibular canine started tooth formation.

Materials: The material consists of orthopantomograms with ectopic mandibular canines and presence of primary mandibular canines from 47 cases (29 cases 9-21 years old and 18 cases with unknown ages). The primary canines demonstrated from minor apical resorption to more severe apical resorption.

Methods: Based on canine maturity, location of the canine axes and the interrelationships between the roots of the permanent canine and first premolar, the location from where the canine started tooth formation was determined. Canine maturity. Maturity stage below half root length and maturity stage above half root length revealed that 11 ectopic canines had less than half root length and 36 cases more than half root length. Canine axes. The canine axis, through the length of the primary canines Ax, is inserted on drawings of the orthopantomograms using the tracing programme Inkscape®. Interrelationship between roots. By visual inspection, the distance between the canine and first premolar was designated close distance, normal distance and extended distance.

Results: The results are divided into 3 groups. Group 1: The initial site of the permanent ectopic canine is located within the canine axis (6 cases). Group 2: The initial site of the permanent ectopic canine is located posterior to the canine axis (36 cases). Group 3: The initial site of the permanent ectopic canine is located anterior to the canine axis (5 cases).

Conclusion: The study explained that the canine axis could divide cases of ectopic canines into three groups according to the location from where tooth formation starts. For getting closer to the pattern of the ectopic canine eruption, it is necessary to analyse series of orthopantomograms taken from the same individual over several years.

前言以前对牙齿发育异常(非犬齿异位)的幼儿进行的一项正侧位研究表明,与稳定的纵向犬齿轴相比,下颌犬齿的齿芽可以正常地位于前方或后方,与第一前磨牙关系密切:材料:材料包括 47 个病例(29 例 9-21 岁,18 例年龄未知)的下颌异位犬齿和原发性下颌犬齿的正侧位图。原生犬齿表现为轻微的根尖吸收和较严重的根尖吸收:方法:根据犬齿的成熟度、犬齿轴的位置以及恒牙根与第一前磨牙之间的相互关系,确定犬齿开始形成牙齿的位置。犬齿成熟度。低于半根长度的成熟阶段和高于半根长度的成熟阶段显示,11 个异位犬齿的根长低于半根长度,36 个异位犬齿的根长超过半根长度。犬轴。使用 Inkscape® 描图程序在正侧位图上插入通过主犬齿长度 Ax 的犬齿轴。牙根之间的相互关系。通过目测,将犬齿和第一前臼齿之间的距离分为近距离、正常距离和远距离:结果分为三组。第一组:永久异位犬齿的初始部位位于犬齿轴内(6 例)。第二组:永久性异位犬齿的初始部位位于犬轴后方(36 例)。结论:研究表明,根据牙齿形成的起始位置,犬齿轴可将异位犬齿病例分为三组。为了更接近异位犬齿萌出的模式,有必要对同一人数年内拍摄的一系列正畸照片进行分析。

Caries experience in children with molar-incisor hypomineralisation in Fujairah, United Arab Emirates and its association with hypomineralised teeth number. 阿拉伯联合酋长国富查伊拉臼齿-切牙低矿化儿童的龋病经历及其与低矿化牙齿数量的关系。
IF 2.3 Q2 DENTISTRY, ORAL SURGERY & MEDICINE Pub Date : 2024-04-01 Epub Date: 2024-02-27 DOI: 10.1007/s40368-024-00867-w
M Brejawi, A Venkiteswaran, S M O Ergieg, B A Md Sabri

Background: Molar-incisor hypomineralisation (MIH) has been found associated with an increase in dental caries. Studies utilising the recent MIH diagnosis and calibration criteria recommended by the EAPD in 2021 are very scarce. Additionally, the available data in literature about the relationship between the hypomineralised teeth number (HTN) and caries come from only one study.

Purpose: To assess the relationship between MIH and caries experience among children in the city of Fujairah, UAE, utilising the recent criteria recommended by the European Academy of Paediatric Dentistry (EAPD) in 2021, and to assess the relationship between the number of teeth affected with MIH, and dental caries.

Methods: One hundred and sixty-two children were included in this cross-sectional study, aged 7-9 years old. Children were examined for MIH according to Ghanim et al. (Eur Arch Paediatr Dent 16:235-246, 2015. 10.1007/s40368-015-0178-8) criteria and Ghanim et al. (Eur Arch Paediatr Dent 18:225-242. 10.1007/s40368-017-0293-92017) training manual. Caries experience was assessed with decayed, missing, filled (dmft, DMFT) scoring system.

Results: dmft mean was 6.56 (SD ± 3.78) and DMFT mean was 0.91 (SD ± 1.23). Children with MIH had significantly higher dmft (p = 0.003) scores. Children with higher HTN had significantly higher dmft (p = 0.008) scores.

Conclusion: Children in Fujairah have extremely high caries scores. Children with MIH have more decayed, missing and filled teeth. Hypomineralised teeth number was positively associated with caries experience.

背景:研究发现,磨牙-尖牙低矿化(MIH)与龋齿的增加有关。利用欧洲牙科诊所(EAPD)于 2021 年推荐的最新 MIH 诊断和校准标准进行的研究非常少。目的:根据欧洲儿童牙科学会(EAPD)2021年推荐的最新标准,评估阿联酋富查伊拉市儿童MIH与龋齿之间的关系,并评估受MIH影响的牙齿数量与龋齿之间的关系:这项横断面研究共纳入了 162 名 7-9 岁的儿童。根据 Ghanim 等人(Eur Arch Paediatr Dent 16:235-246, 2015. 10.1007/s40368-015-0178-8)的标准和 Ghanim 等人(Eur Arch Paediatr Dent 18:225-242. 10.1007/s40368-017-0293-92017)的培训手册对儿童进行 MIH 检查。结果:dmft平均值为6.56(SD±3.78),DMFT平均值为0.91(SD±1.23)。MIH患儿的dmft评分明显更高(p = 0.003)。患有高血压的儿童的 dmft 分数明显更高(p = 0.008):结论:富查伊拉儿童的龋齿评分极高。结论:富查伊拉儿童的龋齿评分极高,患有MIH的儿童有更多的蛀牙、缺失牙和填充牙。低矿化牙齿的数量与龋齿经历呈正相关。

Purpose: Pulpectomy can be used for the management of deep dentinal carious lesions in primary teeth which can be restored. Mechanical preparation of root canals can be performed using hand or NiTi rotary files. However, this may cause dentinal stress and consequently dentinal microcracks. Hence, the aim was comparative evaluation of hand and rotary file systems on dentinal microcrack formation during pulpectomy procedure in primary teeth.

Methods: 60 extracted primary molar teeth were selected comprising of 80 root canals. Simple random sampling was used to divide root canals into four groups (n = 20): Group A-Hedstrom file, Group B-Pro AF Baby Gold rotary, Group C-ProTaper Next rotary, and Group D-unprepared group. Assessment was conducted on presence or absence of microcracks using Chi square test (p < 0.05).

Results: The total number of microcracks in Group A: one (5%), Group B: four (20%), Group C: nine (45%) and Group D: zero (0%) which was statistically significant (p = 0.002). At cervical third, the number of microcracks seen with Group A: one (5%), Group B: zero (0%), Group C: five (25%) and Group D: zero (0%) (p = 0.005). At the middle third, the number of microcracks seen in Group A: zero (0%), Group B: four (20%), Group C: four (20%) and Group D: zero (0%) (p = 0.029).

Conclusion: The study concluded that dentinal microcracks are formed with both hand and rotary file systems in primary teeth. ProTaper Next showed significantly higher number of microcracks, followed by ProAF Baby Gold and H files.

目的:牙髓切除术可用于治疗可修复的乳牙深层牙髓龋坏。可以使用手工或镍钛旋转锉对根管进行机械预备。然而,这可能会造成牙本质应力,从而导致牙本质微裂缝。因此,该研究旨在比较评估手工锉和旋转锉系统在乳牙牙根管切除术中牙本质微裂纹的形成情况。采用简单随机抽样法将根管分为四组(n = 20):A 组-Hedstrom 锉,B 组-Pro AF Baby Gold 旋转器,C 组-ProTaper Next 旋转器,D 组-未准备组。采用卡方检验(P)对是否存在微裂缝进行评估:A 组微裂缝总数为 1 条(5%),B 组为 4 条(20%),C 组为 9 条(45%),D 组为 0 条(0%),差异有统计学意义(P = 0.002)。在宫颈三分之一处,微裂缝的数量为:A 组 1 条(5%),B 组 0 条(0%),C 组 5 条(25%),D 组 0 条(0%)(P = 0.005)。在中间三分之一处,A 组的微裂纹数量为 0(0%),B 组为 4(20%),C 组为 4(20%),D 组为 0(0%)(p = 0.029):该研究得出的结论是,手工和旋转锉系统都会在基牙上形成牙本质微裂纹。ProTaper Next的微裂纹数量明显较多,其次是ProAF Baby Gold和H锉。
