摘要

背景:据文献报道,强直和替代性吸收(ARR)的发病率差异很大,而且大多数研究的患者人数相对较少。本回顾性研究的目的是根据对撞击牙的计算机断层扫描(CT)/锥形束计算机断层扫描(CBCT)的大量样本,概述 ARR 的患病率、位置和相关风险因素。这些结果应能让临床医生更好地估算撞击牙的 ARR 风险:方法:根据预先确定的资格标准,对中欧某中心 5764 名患者的 CT/CBCT 扫描结果进行筛选。对最终纳入的人群记录了以下参数:性别、年龄、牙齿类型/位置、每位患者的阻生齿数量以及是否存在 ARR。此外,还记录了有 ARR 的牙齿在牙弓中的位置、牙齿角度以及受 ARR 影响的牙齿部位:结果:共纳入了 4142 名患者的 7170 颗阻生牙。在 157 名患者(3.7%)中,有 187 颗阻生牙(2.6%)被确诊为 ARR;其中 58% 的患者为女性,每位患者患有 ARR 的牙齿数量从 1 颗到 10 颗不等。根据牙齿类型的不同,发病率从 0(上第一前磨牙、下中切牙和侧切牙)到 41.2%(上第一磨牙)不等。ARR在牙冠(57.2%)、牙根(32.1%)或两者(10.7%)均可检测到。在对混杂因素进行校正后,随着年龄的增长,ARR 的几率明显增加;此外,门牙和第一/第二磨牙的 ARR 几率最高,而智齿的几率最低。更具体地说,对于 20 岁的患者来说,门牙和第一/第二磨牙受撞击时的 ARR 风险在 7.7%至 10.8%之间,但对于 40 岁的患者来说,风险大约增加了两倍,达到 27.3%至 35.5%。此外,女性患者牙根受 ARR 影响的频率明显较低,而随着年龄的增长,牙根受 ARR 影响的频率明显高于牙冠:结论:影响牙根的 ARR 确实很少见,即在 7170 颗影响牙中,只有 2.6% 的牙根强直并伴有替代吸收的迹象。就患者而言,年龄越大,发生 ARR 的几率越高;就牙齿而言,门牙和第一/第二磨牙发生 ARR 的几率最高,而智齿发生 ARR 的几率最低。

Prevalence and characteristics of and risk factors for impacted teeth with ankylosis and replacement resorption - a retrospective, 3D-radiographic assessment.

Background: Large variation in the prevalence of ankylosis and replacement resorption (ARR) is reported in the literature and most studies have relatively small patient numbers. The present retrospective study aimed to provide an overview on prevalence, location of, and associated risk factors with ARR based on a large sample of computed tomography (CT) / cone beam computed tomography (CBCT) scans of impacted teeth. The results should allow clinicians to better estimate the risk of ARR at impacted teeth.

Methods: The CT/CBCT scans of 5764 patients of a single center in Central Europe were screened with predefined eligibility criteria. The following parameters were recorded for the finally included population: gender, age, tooth type/position, number of impacted teeth per patient, and presence/absence of ARR. For teeth with ARR the tooth location in reference to the dental arch, tooth angulation, and part of the tooth affected by ARR were additionally registered.

Results: Altogether, 4142 patients with 7170 impacted teeth were included. ARR was diagnosed at 187 impacted teeth (2.6%) of 157 patients (3.7%); 58% of these patients were female and the number of teeth with ARR per patient ranged from 1 to 10. Depending on the tooth type the prevalence ranged from 0 (upper first premolars, lower central and lateral incisors) to 41.2% (upper first molars). ARR was detected at the crown (57.2%), root (32.1%), or at both (10.7%). After correcting for confounders, the odds for ARR significantly increased with higher age; further, incisors and first/second molars had the highest odds for ARR, while wisdom teeth had the lowest. More specifically, for 20-year-old patients the risk for ARR at impacted incisors and first/second molars ranged from 7.7 to 10.8%, but it approximately tripled to 27.3-35.5% for 40-year-old patients. In addition, female patients had significantly less often ARR at the root, while with increasing age the root was significantly more often affected by ARR than the crown.

Conclusion: ARR at impacted teeth is indeed a rare event, i.e., only 2.6% of 7170 impacted teeth were ankylosed with signs of replacement resorption. On the patient level, higher age significantly increased the odds for ARR and on the tooth level, incisors and first/second molars had the highest odds for ARR, while wisdom teeth had the lowest.

期刊介绍: Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors. It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas: • Mechanisms to improve orthodontics • Clinical studies and control animal studies • Orthodontics and genetics, genomics • Temporomandibular joint (TMJ) control clinical trials • Efficacy of orthodontic appliances and animal models • Systematic reviews and meta analyses • Mechanisms to speed orthodontic treatment Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be: • Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems • Review articles on current topics • Articles on novel techniques and clinical tools • Articles of contemporary interest
