Abstract

Aim

The aim of the present study was to assess the clinical accuracy APEX and 0.5 marks of three different apex locators – iPex II, Root ZX, and Apex ID – before and after canal preparation in the mandibular first molar.

Methods

Sixty patients between the ages of 13-60 years participated in the study. After access gaining and canal preparation stages files were inserted with the apex locator clip attached until the electronic apex locators (EALs) shows readings of APEX and 0.5 marks and same is confirmed with periapical radiographs. Eighteen apex locator readings were recorded from each tooth, and 1080 readings were obtained from the 60 patients.

Results

Differences among readings from apex locators and radiographic readings were assessed using paired t test. Only in two patients (1 male and 1 female) were the APEX mark readings different from the radiograph estimation. When the 0.5 mark readings of three different EALs were compared with each other, we could observe that the readings from Root ZX differed significantly (P < 0.05).

Conclusions

In the present study, we observed the negligible differences in readings between the EAL at the APEX mark readings, coinciding with the radiographic observation. Clinically, we recommend the apical foramen be located with the apex locators’ APEX mark readings prior to identifying the apical constriction position.

不可逆性牙髓炎患者下颌第一磨牙牙尖周x线片与三种不同牙尖定位仪测定工作长度的比较:一项随机对照临床试验

目的评价iPex II、Root ZX、APEX ID三种不同的牙尖定位器在下颌第一磨牙根管预备前后的临床准确性。方法选取年龄在13 ~ 60岁之间的60例患者进行研究。在获得通道和根管准备阶段后，插入带有尖定位夹的文件，直到电子尖定位器(EALs)显示apex和0.5分的读数，并与根尖周围x线片确认。每颗牙齿记录了18个顶点定位仪读数，60名患者获得了1080个读数。结果采用配对t检验评估顶点定位仪读数与x线摄影读数之间的差异。只有2例患者(1男1女)的APEX标记读数与x线片估计不同。当比较三种不同EALs的0.5标记读数时，我们可以观察到Root ZX的读数差异显著(P <0.05)。结论在本研究中，我们观察到EAL与APEX标记读数之间的读数差异可以忽略不计，与x线观察相吻合。临床上，我们建议在确定根尖收缩位置之前，先用顶点定位器的顶点标记读数来定位根尖孔。

期刊介绍： Journal of Investigative and Clinical Dentistry (JICD) aims to publish quality, peer reviewed original research and topical reviews on all aspects of investigative and clinical dentistry and craniofacial research, including molecular studies related to oral health and disease. Although international in outlook, the Editor especially encourages papers from the Asia Pacific. The journal also aims to provide clinicians, scientists and students of dentistry with a knowledge transfer platform for rapid publication of reports through an international journal, which will be available free online until 2012. Its scope, therefore, is broad, inclusive and international, but with a particular focus on Asia Pacific. The Editor welcomes manuscripts in the following key thematic areas in oral and maxillofacial sciences: Community Dentistry and Oral Epidemiology, Conservative Dentistry, Dental Biomaterials, Dental Pedagogy, Endodontics and Traumatology, Implant Dentistry, Oral Biosciences, Oral and Maxillofacial Surgery, Oral Medicine, Oral Pathology and Oral Microbiology, Orthodontics, Oral Radiology, Oral Rehabilitation, Paedodontics, Periodontology and Periodontal Medicine.
