Accuracy of Selective Enamel Etching: A Computer-assisted Imaging Analysis.
Objective: To assess the accuracy of selective enamel etching (SEE) in a laboratory setup simulating clinical conditions.
Methods and materials: A model with permanent human teeth was fabricated. It included a first mandibular molar with a mesio-occlusal-distal inlay preparation, a maxillary central incisor, and a canine with a class IV and class V cavity, respectively. Two dentists (with 1 year and 10 years work experience) repeatedly (n=10 per cavity) performed SEE with a custom gel that had identical rheological properties as a commercially available phosphoric acid etchant. An intraoral scanner was used for image acquisition. To assess the accuracy of SEE, special software was used (OraCheck, Cyfex, Zurich, Switzerland). Two independent investigators analyzed baseline scans and scans taken of the cavities while the gel was in place. The statistical analysis comprised t-tests, Pearson correlation, and analysis of variance (α=0.05).
Results: The level of accuracy, whose average values ranged from 61.1% to 87.0%, showed significant differences between teeth, with the highest level observed in the class V cavity, followed by the class II inlay preparation and the class IV cavity (p<0.001). Across the cavities, no significant correlation was observed between the application time and the accuracy of SEE (p=0.07).
Conclusion: This laboratory study suggests that inadvertent conditioning of dentin adjacent to enamel may be common during SEE. Investigations involving larger samples of dentists are needed to corroborate this finding.
期刊介绍:
Operative Dentistry is a refereed, international journal published bi-monthly and distributed to subscribers in over 50 countries. In 2012, we printed 84 articles (672 pages). Papers were submitted by authors from 45 countries, in the categories of Clinical Research, Laboratory Research, Clinical Techniques/Case Presentations and Invited Papers, as well as Editorials and Abstracts.
One of the strong points of our journal is that our current publication time for accepted manuscripts is 4 to 6 months from the date of submission. Clinical Techniques/Case Presentations have a very quick turnaround time, which allows for very rapid publication of clinical based concepts. We also provide color for those papers that would benefit from its use.
The journal does not accept any advertising but you will find postings for faculty positions. Additionally, the journal also does not rent, sell or otherwise allow its subscriber list to be used by any other entity
