Application of the Intraoral Scanner in the Diagnosis of Dental Wear: An In Vivo Study of Tooth Wear Analysis

Abstract

In recent years, there has been an increase in the incidence of dental wear; thus, an early diagnosis is important. Conventional methods of diagnosis are based primarily on the visual abilities of the dentist, and therefore the use of new technologies for the detection of dental wear may be very useful. The aim of the study was to analyze the sensitivity and specificity of the intraoral scanner for measuring dental wear, as well as to evaluate patients’ satisfaction with the use of the scanner. The study was conducted with 46 volunteers who underwent three intraoral analyses: a first baseline scanning, a second scanning after 6 months and a final scanning after one year performed by four operators divided into two groups. One of the operators performed the visual analysis of dental wear, and the other performed the analysis using the intraoral scanner 3M™ True Definition intraoral scanner (ESPE, Seefeld, Germany). The data obtained from the intraoral scanner showed levels of specificity and sensitivity that enable the intraoral scanner to be used as a diagnostic tool in the assessment of tooth wear. The participants also showed a high degree of satisfaction with the scanner as a communication tool.

Effect of defect size and tooth anatomy in the measurements of a 3D patient monitoring tool

“…Another investigation evaluated the sensitivity of the IOs for measuring dental wear (6 and 12 months follow-up) as well as the patients' satisfaction with the use of the scanner [ 12 ]. According to their findings, the IOs showed promising levels of sensitivity to be applied as a diagnostic tool for tooth wear assessment, while the patient satisfaction was positive in all cases [ 12 ].…”

According to their findings, the IOs showed promising levels of sensitivity to be applied as a diagnostic tool for tooth wear assessment, while the patient satisfaction was positive in all cases [ 12 ]. As a complementary investigation, the present study corroborates with the literature affirming that the use of IOs is useful and can provide an methodological procedure for the wear assessment in daily clinics [ 10 , 11 , 12 ].…”

“…In addition, these optical devices have been successfully used to screening periodontal issues, caries and even as a complementary tool for diagnostic assessment [ 3 , 10 ]. However, the proper follow-up of tooth wear using IOs is still scarce in literature [ 11 , 12 ].…”

“…Nowadays, with the aid of IOs and patient monitoring software, the assessment of surface changes in the teeth during periodic follow-up seems to be a reliable method in preventive dentistry [ 11 , 12 ]. Basically, to calculate the amount of tooth wear, a baseline digital impression can be compared tooth by tooth (segmenting) with the new digital impression after a period of time.…”

Enamel Wear of Antagonist Tooth Caused by Dental Ceramics: Systematic Review and Meta-Analysis

“…The model or the initial and final images to measure the difference between them vary from study to study [ 24 ]. However, the use of the intraoral scanner is currently being opted for, which helps to obtain the samples directly from a three-dimensional image [ 25 ]. Some researchers [ 4 , 12 , 21 ] used to apply a spray before obtaining the image, which could lead to distortion in the image [ 26 ], as well as data loss when transferring the captured images to STL format [ 27 ].…”
