This study aimed to perform clinical and radiographic investigations of the effect of regenerative endodontic procedures (REPs) with and without concentrated growth factor (CGF). Fifty-six non-vital and immature teeth from 56 patients were randomly categorized into two groups. Following chemical and mechanical preparation, REPs with and without CGF as a scaffold was induced in the blood clot (BLC) group and the CGF group. All patients were clinically and radiographically evaluated at 6-month and 12-month intervals to monitor their progress and treatment outcomes. When considering the total number of patients, the follow-up rate was 96.4% (54 out of 56 patients) over a 12-month period. Favorable clinical and radiographic outcomes were observed in 92.6% of patients (25 out of 27) in both the CGF and BLC groups; there were no significant differences between the two groups in these respects (p > 0.05). Notable differences were, however, observed in radiographic measurements relating to the development of root length and radiographic root area when compared between the CGF and BLC groups at both the 6-month and 12-month follow-up intervals (p < 0.05). REPs have been proven to represent a conservative and effective approach for promoting maturogenesis in non-vital and immature teeth. Furthermore, the incorporation of CGF as scaffolds holds promising potential for enhancing the desired biological outcomes of this regenerative technique. These findings highlight the clinical significance and potential benefits of CGF supplementation in REPs, further supporting its application in the field of endodontics.

This study evaluated 10-year secular changes in dental maturity and dental development among Korean children. A retrospective analysis of panoramic radiograph samples from Korean children (4-16 years old) taken in 2010 and 2020 was conducted. The 2010 group consisted of 3491 radiographs (1970 boys and 1521 girls), and the 2020 group included 5133 radiographs (2825 boys and 2308 girls). Using Demirjian's method, dental maturity scores and dental developmental stages were assessed. For intra-observer reliability, Weighted Cohen's kappa was used, and Mann-Whitney U tests were performed to compare the 2020 and 2010 groups. A slight acceleration in dental maturity was observed in both boys and girls, with the difference being more noticeable in boys at an earlier age. Statistically significant differences were noted at ages 4, 5 and 7 for boys, and at age 6 for girls. Despite these differences, the individual dental development stages of 2020 and 2010 showed inconsistent trends with limited differences. Generally, girls demonstrate more advanced dental maturity than boys. A slight acceleration in Korean children's dental maturity was observed over a 10-year period when comparing the 2020 groups to the 2010 groups.

This study aimed to assess the changes in interproximal contacts before and after orthodontic treatment using the OXIS classification. OXIS refers to the types of contacts that is open (O), point contact (X), straight contact (I), and curved contact (S), and thus the acronym "OXIS". Interproximal contact data of 30 orthodontic patients were obtained at three time points: T0, at the beginning of treatment; T1, at the end of fixed appliance treatment; and T2, one-year post-treatment. For the maxillary second molar-first molar contact, the most common contact at T0, was the "S" pattern (41.6%) which increased to 61.6% at T1 and reduced to 48.3% at T2. For the maxillary first molar-second premolar contact, maxillary second premolar-first premolar contact, and maxillary first premolar-canine contact, the most common contact at T0 was the "I" pattern (58.3%, 46.5% and 43.3%, respectively), which increased to 88.3%, 93.3% and 73.3%, respectively at T1 and decreased to 80%, 88.3% and 71.6%, respectively at T2. For the maxillary canine-lateral incisor contact and lateral-central incisor contact, the most common contact at T0 was the "O" pattern (45% and 33.3%) while it was the "X" pattern at T1 (63.3% and 80%) and T2 (58.3% and 80%). A similar observation was made for the posterior mandibular and anterior teeth. There was statistical significance for most of the changes in the mandibular contacts (p ˂ 0.05). Interproximal contacts change significantly from T0 to T1. Broader contacts were normal at T1 and T2 in the posterior segments. At T2, changes in the interproximal contacts were observed in the posterior segments, and substantial evidence was available, particularly for the mandibular arch.

Dental general anaesthesia provides a comfortable treatment modality for children with early childhood caries and children's dental anxiety, but US Food and Drug Administration safety warnings have raised concerns about the neurotoxicity of general anaesthetic drugs. Currently, anaesthetic drugs have been found to impair neurocognitive function in animals, with possible mechanisms including cell damage, cell loss and impaired neuronal network function. The outcomes of clinical studies on the neurocognitive effects of surgical general anaesthesia in children have been inconsistent. However, studies focusing on dental general anaesthesia in children suggest that it does not affect neurocognitive function. In general, a growing number of studies suggest that dental general anaesthesia does not affect neurocognitive development in children. Moreover, dental general anesthesia should be used as normal when other behavioural management is unavailable.

Dental decay is a prevalent bacterial disease affecting a significant percentage of children globally. In paediatric dentistry, various materials are available for restoring deciduous teeth, addressing both functional and aesthetic concerns. However, paediatric dentists encounter challenges related to patient compliance, limited working time, and material handling. This study aims to observe the survival rate of bulk-fill composite restorations in paediatric patients over a five-year follow-up. A total of 198 patients aged 0 to 12 years underwent 673 class II restorations on deciduous first molars (1M) and second molars (2M). All restorations were conducted performed by 1 Pediatric DDS resident students from the Paediatric Dentistry Department (Padova University), utilizing using different isolation techniques. Bulk-fill composite restorations were evaluated over a five-year follow-up, and data were collected by a single investigator. After five years, 177 patients and 611 restorations were assessed. The retention rate was higher in primary second molars than in first molars, with fewer marginal dyschromies and less formation of secondary caries. The overall failure rate was higher in primary first molars and primary lower second molars. Bulk-fill composites demonstrated significantly positive performance in terms of retention, maintenance, and marginal dyschromies. Bulk-fill composites are promising materials of choice in paediatric dentistry due to their easy handling and favorable properties. Further research is necessary to compare high and low viscosity bulk-fill composites and assess the impact of different variables on restoration success.

This study aimed to characterize the anatomical and physiological features of pits and fissures in primary and permanent molars by microtomographic (micro-CT) examination and three-dimensional (3D) printing. The occlusal surfaces of 84 primary molars and 60 permanent third molars were examined. The samples were scanned with micro-CT and the occlusal surface separated. The areas of the crown, its occlusal part, and fissures and pits were calculated. Digital impression of the occlusal surface was created and 3D printed. The frequency of different fissure types was determined by direct observation. Data were subjected to statistical analysis using Mann-Whitney U Test and chi-square test (p < 0.05). There was statistically significant difference between the ratio of occlusal surface and the crown area for the molars in primary and permanent dentitions (24.78% and 28.85% respectively, p < 0.05). In terms of the percentage ratio of the fissure area to the occlusal surface (24.24% and 22.30%) and the fissure area to the crown (6.02% and 6.52%), no significant difference was observed (p > 0.05). V-shaped fissures were predominant in both primary and permanent teeth, with a higher occurrence in primary dentition (59.48%, p < 0.05). Permanent molars exhibited a higher prevalence of I-type and U-type fissure configurations compared to primary molars (p < 0.05), with I-type fissures being the least common in primary molars. In both dentitions there was no statistically significant difference in the prevalence of IK-configuration (p > 0.05). The fissure depth was significantly greater in permanent molars than primary molars (p < 0.05). In conclusion, this study revealed remarkable diversity in fissure morphology among primary and permanent molars.
本研究旨在通过显微层析成像(micro-CT)检查和三维(3D)打印技术,确定基牙和恒磨牙凹陷和裂隙的解剖和生理特征。对 84 颗初级磨牙和 60 颗永久性第三磨牙的咬合面进行了检查。用显微 CT 扫描样本并分离咬合面。计算牙冠、其咬合部分以及裂隙和凹坑的面积。创建并 3D 打印咬合面的数字模型。通过直接观察确定不同裂隙类型的频率。数据采用 Mann-Whitney U 检验和卡方检验进行统计分析(P < 0.05)。基牙和恒牙的磨牙咬合面与牙冠面积的比例差异有统计学意义(分别为 24.78% 和 28.85%,P < 0.05)。在裂隙面积与咬合面的百分比比(24.24% 和 22.30%)和裂隙面积与牙冠的百分比比(6.02% 和 6.52%)方面,没有观察到显著差异(P > 0.05)。基牙和恒牙中均以 V 形窝沟龋为主,其中基牙的发生率更高(59.48%,p < 0.05)。与基牙相比,恒磨牙的 I 型和 U 型窝沟的发生率更高(p < 0.05),其中 I 型窝沟在基牙中最不常见。在这两种牙列中,IK型窝沟的发生率没有明显的统计学差异(p > 0.05)。恒磨牙的裂隙深度明显大于原磨牙(p < 0.05)。总之,这项研究揭示了基牙和恒磨牙裂隙形态的显著多样性。

Mandibular asymmetry refers to dimensional differences between the left and right sides of the mandible in terms of size, form and volume. This condition may result in problems with functionality as well as appearance. Early intervention is often deemed optimal for addressing mandibular asymmetry; however, there is a lack of consensus regarding the diagnostic approach and strategy for identifying asymmetries in developing individuals. The purpose of this narrative review (NR) is to provide a clinician-focused update on the radiographic techniques for identifying mandibular asymmetries in orthodontic patients. Selective database searches were conducted until November 2023 to assess the available literature on mandibular asymmetry diagnosis. A health-sciences librarian developed a search strategy utilizing appropriate terms associated with mandibular asymmetry diagnosis. The databases used were Web of Science, Embase, Scopus, Liliacs and PubMed. Fifty-two studies were included in this review and data regarding the evaluation of mandibular asymmetries were presented with a narrative approach delineating clinical indications based on retrieved findings. There is no unanimous consensus on the method for diagnosing mandibular asymmetries. Cone beam computed tomography emerges as the preferred examination method for diagnosing mandibular asymmetry, thanks to the assessment of a 3D structure with a 3D image. However, the use of only orthopantomography could be advisable as a first-line diagnostic tool in children due to less radiation exposure.
下颌骨不对称是指下颌骨左右两侧在大小、形态和体积方面存在尺寸差异。这种情况可能会导致功能和外观方面的问题。早期干预通常被认为是解决下颌骨不对称问题的最佳方法;然而,对于识别发育中个体下颌骨不对称的诊断方法和策略还缺乏共识。本叙事性综述(NR)的目的是以临床医生为中心,提供有关识别正畸患者下颌不对称的放射学技术的最新信息。为了评估有关下颌不对称诊断的现有文献,我们在 2023 年 11 月之前对数据库进行了选择性检索。一位健康科学图书管理员利用与下颌不对称诊断相关的适当术语制定了检索策略。使用的数据库包括 Web of Science、Embase、Scopus、Liliacs 和 PubMed。本综述共收录了 52 项研究,并根据检索到的结果,以叙述的方式描述了临床适应症,介绍了有关下颌不对称评估的数据。对于下颌骨不对称的诊断方法,目前还没有一致的共识。锥形束计算机断层扫描是诊断下颌骨不对称的首选检查方法,因为它能通过三维图像评估三维结构。不过,由于辐射量较少,仅使用正位断层扫描作为儿童的一线诊断工具也是可取的。

This clinical trial aimed to evaluate and compare the retention and cariostatic effects of hydrophilic and hydrophobic resin-based sealants (RBSs) for sealing pits and fissures in the permanent molars of uncooperative children. A split-mouth and double-blind randomized clinical trial (RCT) was conducted among 6- to 9-year-old uncooperative children. One hundred and four sound mandibular and maxillary first permanent molars were randomly allocated to be sealed with group I (UltraSeal XT® hydro™) or group II (Helioseal-F) in 34 uncooperative children. Clinical evaluation was performed by two investigators using the Color, Coverage and Caries system to assess sealant retention and cariostatic effect at 3-, 6- and 12-month intervals. Data analysis was performed using Friedman's and Mann-Whitney U tests. The final analysis included 31 children with 49 pairs of teeth. No significant differences were observed between the retention and cariostatic effects of hydrophilic and hydrophobic RBSs at the 3-, 6- and 12-month intervals (p = 0.23, p = 0.638, and p = 0.706, respectively) (p = 0.175, p = 0.065, and p = 0.171, respectively). After 12 months of follow-up, the hydrophilic RBSs showed an outcome equivalent to that of conventional hydrophobic RBSs in terms of retention and cariostatic effects. Therefore, hydrophilic RBSs could be considered as the sealing material of choice when isolation is difficult, particularly in uncooperative children.
这项临床试验旨在评估和比较亲水性树脂封闭剂和疏水性树脂封闭剂(RBSs)在封闭不合作儿童恒磨牙凹陷和裂隙时的固位和抗龋效果。我们在 6 至 9 岁不合作的儿童中开展了一项分口双盲随机临床试验(RCT)。在 34 名不合作的儿童中随机分配了 14 颗健全的下颌和上颌第一恒磨牙,分别使用第一组(UltraSeal XT® hydro™)或第二组(Helioseal-F)进行封闭。由两名研究人员使用颜色、覆盖率和龋坏系统进行临床评估,在3个月、6个月和12个月的时间间隔内评估密封剂的保持力和防龋效果。数据分析采用弗里德曼检验和曼-惠特尼 U 检验。最终分析包括 31 名儿童的 49 对牙齿。在 3 个月、6 个月和 12 个月的间隔期内,亲水性和疏水性 RBS 的固位和抗龋效果没有明显差异(分别为 p = 0.23、p = 0.638 和 p = 0.706)(分别为 p = 0.175、p = 0.065 和 p = 0.171)。经过 12 个月的随访,亲水性 RBS 在保留和止血效果方面的结果与传统的疏水性 RBS 相当。因此,亲水性 RBS 可作为隔离困难时的首选密封材料,尤其是对于不合作的儿童。

Zimmermann-Laband Syndrome (ZLS; MIM 135500) is a rare genetic disorder with the main clinical manifestations of gingival fibromatosis and finger/toe nail hypoplasia. KCNH1 (potassium channel, voltage-gated, subfamily H, member-1), KCNN3 (potassium channel, voltage-gated, subfamily H, member-3) and ATP6V1B2 (ATPase H+ transporting V1 subunit B2) genes are considered causative genes for ZLS. However, there are limited reports about the diverse clinical presentation and genetic heterogeneity. Reporting more information on phenotype-genotype correlation and the treatment of ZLS is necessary. This case reported a 2-year-old patient with gingival enlargement that failure of eruption of the deciduous teeth and severe hypoplasia of nails. Based on a systemic examination and a review of the relevant literature, we made an initial clinical diagnosis of ZLS. A novel pathogenic variant in the KCNH1 gene was identified using whole-exome sequencing to substantiate our preliminary diagnosis. The histopathological results were consistent with gingival fibromatosis. Gingivectomy and gingivoplasty were performed under general anesthesia. After surgery, the gingival appearance improved significantly, and the masticatory function of the teeth was restored. After 2-year follow-up, the gingival showed slightly hyperplasia. Systemic examination and gene sequencing firstly contribute to provide information for an early diagnosis for ZLS, then timely removal of the hyperplastic gingival facilitates the establishment of a normal occlusal relationship and improves oral aesthetics.

This study aims to elucidate the clinical efficacy of Mineral Trioxide Aggregate (MTA) and Bioceramic Materials in pulpotomy procedures for early-stage chronic pulpitis in deciduous teeth. The clinical data of 100 children with early chronic pulpitis in deciduous teeth treated at our institution between January 2021 and January 2023 were included retrospectively, which were divided into an experimental group (n = 50) and a control group (n = 50) according to the treatment methods. Experimental group received pulpotomy with Thera Cal LC as bioceramic pulp-capping material versus control group with MTA as pulp-capping agent. Comparative studies were conducted to assess the clinical effectiveness and differences between both pulp-capping techniques. At 12 months postoperatively, the experimental group showed a significantly higher success rate than the control group (96.00% vs. 80.00%, p < 0.05). Post-treatment inflammatory markers (Tumor Necrosis Factor-alpha (TNF-α), Interleukin-6 (IL-6) and Interleukin-8 (IL-8)) were substantially lower in the experimental group (p < 0.05). Furthermore, significantly lower pain scores and higher comfort and satisfaction scores were obtained in the experimental group (p < 0.05). Experimental group adverse reactions were also lower in the experimental group (p < 0.05). TheraCal LC bioceramic material treats early chronic pulpitis in deciduous teeth effectively. Clinically, it is an excellent therapeutic option for emergence of permanent dentition, pain relief, comfort and improvement of patient satisfaction.
