Big Data and Digitalization in Dentistry: A Systematic Review of the Ethical Issues
International journal of environmental research and public health, 2020Co-Authors: Maddalena Favaretto, David Shaw, Eva De Clercq, Tim Joda, Bernice Simone ElgerAbstract:Big Data and Internet and Communication Technologies (ICT) are being increasingly implemented in the healthcare sector. Similarly, research in the field of dental medicine is exploring the potential beneficial uses of Digital data both for dental practice and in research. As Digitalization is raising numerous novel and unpredictable ethical challenges in the biomedical context, our purpose in this study is to map the debate on the currently discussed ethical issues in Digital Dentistry through a systematic review of the literature. Four databases (Web of Science, Pub Med, Scopus, and Cinahl) were systematically searched. The study results highlight how most of the issues discussed by the retrieved literature are in line with the ethical challenges that Digital technologies are introducing in healthcare such as privacy, anonymity, security, and informed consent. In addition, image forgery aimed at scientific misconduct and insurance fraud was frequently reported, together with issues of online professionalism and commercial interests sought through Digital means.

A systematic review about randomized clinical trials on Digital impressions on sound teeth
Journal of Osseointegration, 2019Co-Authors: A. Biagioni, M. Pecciarini, Marco FerrariAbstract:Aim In the dental literature there are a number of studies about Digital impressions. They mainly are focused on the reproducibility of the measurements or on the validity, accuracy, trueness and precision of the scans compared with conventional materials, or on the reaction of patients to these new methods. The purpose of this study was to systematically review existing clinical trials reporting about intra oral scanning procedures on sound teeth. Materials and methods PubMed, Cochrane Library and Web of Science databases were electronically searched and enriched by hand searches. The query terms “randomized clinical trials”, “in vivo study”, “sound teeth”, “intraoral scanner”, “Digital Dentistry” combined with the Boolean operators “OR” and “AND” have been used. No language or time limitation was applied. Selection criteria: oly randomized in vivo studies where sound teeth had been scanned intraorally were considered. Results Twenty-four out of more than three hundred studies were selected for the review. Conclusion In literature there are enough randomized clinical trials about sound teeth. They report about many clinical aspects.

"Digitally Oriented Materials": Focus on Lithium Disilicate Ceramics.
International journal of dentistry, 2016Co-Authors: Fernando Zarone, Marco Ferrari, Francesco Mangano, Renato Leone, Roberto SorrentinoAbstract:The present paper was aimed at reporting the state of the art about lithium disilicate ceramics. The physical, mechanical, and optical properties of this material were reviewed as well as the manufacturing processes, the results of in vitro and in vivo investigations related to survival and success rates over time, and hints for the clinical indications in the light of the latest literature data. Due to excellent optical properties, high mechanical resistance, restorative versatility, and different manufacturing techniques, lithium disilicate can be considered to date one of the most promising dental materials in Digital Dentistry.

Colour stability and surface properties of high-translucency restorative materials for Digital Dentistry after simulated oral rinsing.
European journal of oral sciences, 2020Co-Authors: Jae-hyun Lee, Sung-hun Kim, Hyung-in Yoon, In‐sung L. Yeo, Jung-suk HanAbstract:High-translucency restorative materials are commonly used in the restoration of anterior teeth where aesthetics is a critical factor. In this in vitro study, the impact of mouthwash on the colour stability and surface characteristics of high-translucency computer-aided design and computer-aided manufacturing (CAD-CAM) dental restorative materials was evaluated. Two-hundred specimens were fabricated from five high-translucency CAD-CAM materials: a resin nano ceramic; a polymer-infiltrated ceramic network; a feldspathic ceramic; a lithium disilicate glass ceramic; and high-translucency zirconia. Each group of ceramic specimens was then divided into four subgroups: conventional mouthwash (LISTERINE); whitening mouthwash (LISTERINE Healthy White); chlorhexidine gluconate; and distilled water. Oral rinsing was simulated at 100 rpm for 180 h, representing 15 yr of clinical simulation. The specimens were then evaluated for colour, translucency, gloss, roughness, and surface morphology. Two-way ANOVA and linear mixed models were used for intergroup comparisons (α = 0.05). The polymer-infiltrated ceramic network and feldspathic ceramic became brighter, more opaque, less glossy, and rougher after rinsing with the whitening mouthwash. The long-term use of specific mouthwashes can cause deterioration of the optical and surface properties of high-translucency CAD-CAM dental restorations.

Effects of ultrasonic scaling on the optical properties and surface characteristics of highly translucent CAD/CAM ceramic restorative materials: An in vitro study
Ceramics International, 2019Co-Authors: Jae-hyun Lee, Sung-hun Kim, Jung-suk Han, In-sung Luke Yeo, Hyung-in Yoon, Jungwon LeeAbstract:Abstract Esthetic restorations using highly translucent ceramics powered by chairside Digital Dentistry are becoming popular. The purpose of this in vitro study was to investigate the impact of ultrasonic scaling on the optical and surface properties of highly translucent ceramic materials for Digital Dentistry. A resin nanoceramic (Lava Ultimate; LU), dual-network ceramic (Vita Enamic; VE), feldspathic ceramic (Vitablocs Mark II; VM), lithium disilicate ceramic (IPS e.max CAD; EX), and high-translucency monolithic zirconia (Rainbow Shine-T; MZ) were evaluated. All specimens were subjected to ultrasonic scaling, and the following data were obtained before and after scaling: color change (Δ E 00 ), translucency parameter, surface gloss, surface roughness, and superficial topography. One-way analysis of variance (ANOVA), repeated-measures ANOVA, and two-way ANOVA were used for intergroup comparisons (all α = 0.05). The mean Δ E 00 values were 0.243, 0.48, 1.591, 0.143, and 4.466 for LU, VE, VM, EX, and MZ, respectively, with statistically significant differences among the materials. With regard to Commission Internationale de l'Eclairage (CIE) L* , a* , and b* values, VE, VM, and MZ showed significantly decreased L* values relative to the baseline values. Moreover, MZ showed a significantly increased a* value and a significantly decreased b* value after scaling. Ultrasonic scaling also resulted in significant changes in the surface gloss of the LU, VE, VM, and MZ specimens. Micrographs showed scrapes and surface deterioration after scaling. For all materials, the translucency parameter and the surface roughness showed no significant differences between specimens that were subjected to scaling and those that were not. These findings suggest that ultrasonic scaling MARKEDLY affects the optical properties and surface characteristics of highly translucent computer-aided design and computer-aided manufacturing (CAD/CAM) ceramics. The findings can aid restorative dentists in the selection of appropriate materials and motivate periodontists for performing scaling procedures with due consideration of restorations in esthetically demanding areas.
