    This case report presents the successful management of a four-year-old male patient with pain in the lower right back tooth region. Clinical and radiographic examinations revealed the necessity for extraction of tooth 85 due to persistent infection and bone resorption, necessitating space maintenance. A modified distal shoe space maintainer, incorporating horizontal loops for enhanced adjustability, was utilized postextraction. The appliance was fabricated, cemented, and monitored through follow-up visits. At the 24-month recall, the permanent mandibular first molar (tooth 46) was clinically visible, indicating successful space maintenance. Incorporating horizontal loops into the distal shoe space maintainer represents an innovative approach in pediatric dentistry, offering clinicians a versatile tool for managing space loss and promoting optimal eruptive patterns.

    目的:牙齿萌出是一个动态的过程。牙尖的任何部分通过牙龈出现可能是皮疹的临床标志。早期儿童龋齿(ECC)是全球范围内的公共卫生问题。这项研究旨在评估父母报告的第一颗牙齿出现时间与幼儿ECC之间的关系。
    方法:本研究是对627名幼儿的二次数据分析,涉及儿童睡眠时间喂养的病例对照研究。根据父母报告的第一颗乳牙出现的时间,将儿童分为四组(G1-当第一颗乳牙在6个月大之前出现时,G2-在7至9个月之间;G3-10至12个月和G4-当第一颗乳牙在12个月大时出现)。进行单变量二元逻辑回归分析以评估第一颗牙齿出现的时间与ECC之间的关联。
    结果:儿童的平均年龄为24.4±7.3个月(例,这是ECC-25.4±6.9个月的儿童,controls,即没有ECC-23.6±7.5个月的儿童)。60个孩子,他的第一颗牙齿在6个月大之前就长出了,35例(12%)与25例(8%)对照相比。在这些案件中,男生患龋率高于女生(p<0.05)。前牙,在第一组中,22%的牙齿出现了腐烂,其次是19%,16%和10%,第三和第四组,分别为(p<0.05)。对后牙的分析显示,第一乳牙出现延迟的腐烂牙齿百分比较低(p<0.05)。在6个月大之前出现牙齿的儿童的比值比为3.5(95%CI1.49,8.42)(p=0.004)。
    结论:这项研究得出结论,第一颗乳牙的早期出现,根据父母的报告,与患ECC的风险增加有关。
    OBJECTIVE: Tooth eruption is a dynamic process. Appearance of any part of the cusp through gingiva may be a clinical marker of eruption. Early childhood caries (ECC) is a public health problem globally. This study aimed to assess the relationship between parent-reported timing of first tooth emergence and ECC in toddlers.
    METHODS: This study is a secondary data analysis of 627 toddlers involved in a case-control study on sleep-time feeding practises in children. The children were categorised into four groups based on the parent-reported timing of first primary tooth emergence (G1-when the first primary tooth emerged before 6 months of age, G2-between 7 and 9 months; G3-10 to 12 months and G4-when the first primary tooth emerged after 12 months of age). Univariate binary logistic regression analysis was performed to evaluate the association between timing of first tooth emergence and ECC.
    RESULTS: The mean age of the children was 24.4 ± 7.3 months (cases, that is children with ECC-25.4 ± 6.9 months, controls, that is children without ECC-23.6 ± 7.5 months). Of 60 children, whose first tooth erupted before 6 months of age, 35 (12%) were cases compared to 25(8%) controls. Amongst the cases, boys had more caries than girls (p < 0.05). Of the anterior teeth, 22% of the emerged teeth were decayed in the first group, followed by 19%, 16% and 10% in the second, third and fourth groups, respectively (p < 0.05). Analysis of the posterior teeth showed a lower percentage of decayed teeth with delayed emergence of the first primary tooth (p < 0.05). Children whose teeth emerged before 6 months of age had an odds ratio of 3.5 (95% CI 1.49, 8.42) (p = 0.004).
    CONCLUSIONS: This study concluded that the early emergence of the first primary tooth, as reported by the parent, was associated with an increased risk of developing ECC.

    描述在不使用任何矫治器的情况下,与牙质囊肿相关的未喷发前磨牙的成功喷发。
    炎性牙病囊肿是混合牙列中发生的牙病囊肿的一种变体,由于龋齿的根尖周炎症刺激了发育中的恒牙的牙釉质上皮减少,不重要的落叶前体。袋袋化是保留恒牙的首选治疗方法。
    一位10岁的患者向我们展示了一个明确的,涉及左侧下颌体的嫩肿胀,并伴有颊皮质扩张。成像后,进行有袋化,包括广泛切除覆盖该区域的肺泡粘膜以及囊性衬里。在后续行动中,注意到恒牙自发萌出成咬合。
    这表明沿波峰的有袋化可能允许相关的恒牙成功萌出并解决囊肿。
    沿波峰的有袋化提供了一种保守的选择,允许自发,在炎性牙囊肿的情况下,恒牙的无辅助萌出。必须使用仔细的术前评估来做出治疗决定。恒牙的成功萌出和疾病的总体解决都取决于充分的随访。

    UNASSIGNED: To describe the successful eruption of an unerupted premolar associated with a dentigerous cyst without the use of any appliances.
    UNASSIGNED: Inflammatory dentigerous cyst is a variant of dentigerous cyst occurring in the mixed dentition due to stimulation of the reduced enamel epithelium of a developing permanent tooth by periapical inflammation from its carious, nonvital deciduous precursor. Marsupialization is the preferred treatment to preserve the permanent tooth.
    UNASSIGNED: A 10-year-old patient presented to us with a well-defined, tender swelling involving the left mandibular body with buccal cortical expansion. Following imaging, marsupialization was performed involving wide excision of the alveolar mucosa overlying the region along with the cystic lining. At follow-up, spontaneous eruption of permanent teeth into occlusion was noted.
    UNASSIGNED: This suggests that marsupialization along the crest may allow for successful eruption of the associated permanent teeth with the resolution of the cyst.
    UNASSIGNED: Marsupialization along the crest provides a conservative option that allows spontaneous, unassisted eruption of permanent teeth in cases of inflammatory dentigerous cysts. Careful preoperative assessments must be used to make treatment decisions. The successful eruption of permanent teeth and the total resolution of the disease both depend on adequate follow-up.

    第一永久磨牙的异位喷发是局部喷发干扰。在男孩中,异位爆发的第一永久性磨牙的频率占主导地位,主要影响上颌骨。应尽早开始对不可逆的异位喷发进行拦截治疗,以防止空间损失和第二前磨牙的撞击。在这里,我们报告了一例6岁女孩,双侧下颌第一永久性磨牙不可逆异位喷发,舌弓改良。治疗六个月后,下颌第一恒磨牙成功扩张,一年的随访结果令人满意。改良的舌弓不仅满足临床治疗方面的要求,也满足患者的健康。然而,在混合牙列阶段,舌弓可能会干扰牙齿的萌出。
    Ectopic eruption of the first permanent molars is a local eruption disturbance. The frequency of ectopically erupted first permanent molars is predominant in boys and primarily affects the maxilla. Interceptive treatment for irreversible ectopic eruptions should be initiated early to prevent space loss and the impaction of the second premolars. Herein, we report the case of a six-year-old girl with irreversible ectopic eruption of the bilateral mandibular first permanent molarstreated with a modified lingual arch. The mandibular first permanent molars were successfully distalised after six months of treatment, and one year of follow-up showed a satisfactory outcome. The modified lingual arch satisfies not only the clinical aspects of treatment but also the patient\'s well-being. However, the lingual arch may disturb tooth eruption in the mixed dentition stage.

    Dental complications such as defective alveolar bone development, delayed eruption, and tooth impaction are related to neonatal oral intubation. This case report presents an example of potential complications that occur in children who have undergone oral intubation as neonates. A 20-month-old girl visited our pediatric clinic. We observed delayed, non-erupted teeth #51, #71, and #81 and determined a history of intubation during the neonatal period as a related factor. After 22 months of observation, tooth #71 erupted spontaneously. After 40 months of monitoring, teeth #51 and #81 were extracted surgically, and normal permanent teeth erupted six months later. This study is helpful for pediatric anesthesiologists, pediatricians, and dentists who diagnose and treat eruption disorders of the primary dentition.
