Publication date: July 2018 Source:Journal of Dentistry, Volume 74, Supplement 1 Author(s): Qianqian Pan, Stephen Westland Objectives To review the key concepts of color in the dental domain with specific reference to the use of digital technology to measure color and color appearance. Materials and methods The literature on color assessment in dentistry is considered and methods for assessing whiteness, yellowness and color appearance are collated and described. Results and conclusion A variety of methods for assessing color have been shown to exist and be viable including digital imaging. Equations to predict white...

A practice based longevity study on single-unit crowns
Conclusions Overall, crowns placed by a selected group of dentist showed a good to acceptable success and survival rates, mainly dependent from the practice. The presence of an endodontically treated tooth was a significant risk factor leading to more failures. (Source: Journal of Dentistry)

Automatic detection and classification of dental fluorosis in vivo using white light and fluorescence imaging
Conclusions Assessment of dental fluorosis is typically undertaken by clinical examiners in epidemiological studies. The training and calibration of such examiners is complex and time consuming and the assessments are subject to bias – frequently because of the examiner’s awareness of the water fluoridation status of subjects. The use of remote scoring using photographs has been advocated but still requires trained examiners. This study has shown that image-processing methodologies applied to white light and fluorescent images could automatically score fluorosis and statistically separate fluoridated and non-fluoridate...

Perception of children with visible untreated and treated caries
Conclusions Children with visible treated and untreated caries were differently perceived by laypersons and dental experts than children with healthy teeth. (Source: Journal of Dentistry)

Digital epidemiology – Calibrating readers to score dental images remotely
Conclusion Providing examiners theoretical material and scoring criteria prior to training may be minimally sufficient to calibrate examiners to score digital photographs. There may be some benefit in providing an in-person training to discuss criteria and review previously scored images. Previous experience as a clinical examiner seems to provide a slight advantage at scoring photographs for DI, but minimizing the number of scorers does improve inter-examiner concordance for both DI and TF.

Do traditional techniques produce better conventional complete dentures than simplified techniques? A 10-year follow-up of a randomized clinical trial
Conclusion The results indicate that the simplified method remains more cost-efficient than the traditional method over a 10-year period. (IRB approval: A09-E71-12 B McGill University, trial registry: ClinicalTrial.org; NCT02289443) (Source: Journal of Dentistry)

The digital patient – Imaging science in dentistry
Publication date: July 2018 Source:Journal of Dentistry, Volume 74, Supplement 1 Author(s): Bart Vandenberghe Dental imaging has seen a rapid technological advance over the last several years. Not only has most x-ray based diagnostic technology been digitized, with the possibility of low dose 3D computed tomography imaging, but many novel optical imaging techniques have now also been adopted in a more therapeutic imaging of the dental patient. When combining and manipulating such different digital image data, clinicians can now easily plan and simulate treatments on-screen, use 3D printed models and aids to assist in ac...

The ethics of mHealth: Moving forward
Publication date: July 2018 Source:Journal of Dentistry, Volume 74, Supplement 1 Author(s): Tilda Cvrkel There is great power and promise for mobile health (mHealth) technology in the realms of clinical practice and research. By offering the opportunity to reshape the interaction between clinician and patient or researcher and subject, the introduction of this technology allows clinicians and researchers access to larger quantities of more timely and reliable data. The potential developments are significant, and they are ethically relevant. With all technological developments, however, come new sets of ethical risks. In...

Sealing or infiltrating proximal carious lesions
Conclusions Sealing or infiltration are likely to be more efficacious for arresting early (non-cavitated) proximal lesions than NI. Clinical significance Practitioners should strive to perform micro-invasive treatment instead of NI for early proximal lesions. The decision between sealing or infiltration should be guided by practical concerns beyond efficacy. (Source: Journal of Dentistry)

Re-architecting oral healthcare for the 21st century
Publication date: July 2018 Source:Journal of Dentistry, Volume 74, Supplement 1 Author(s): Vivek Shetty, John Yamamoto, Kenneth Yale The convergent forces of rising costs, growing consumerism, expensive new treatments, sociodemographic shifts and increasing health disparities are exerting intense and unsustainable pressures on healthcare systems. As with the other health domains, these disruptive forces demand new approaches and delivery models for oral healthcare. Technological innovations and practices borrowed from the e-commerce and tech sectors could facilitate the move to a sustainable 21st century oral healthc...

Do HEMA-free adhesive systems have better clinical performance than HEMA-containing systems in noncarious cervical lesions? A systematic review and meta-analysis
Conclusions HEMA-free and HEMA-containing adhesive systems showed a similar clinical performance in NCCL restorations. Clinical significance Only the presence of HEMA does not indicate better clinical performance of adhesive systems. (Source: Journal of Dentistry)

Monitoring the progression of erosive tooth wear (ETW) using BEWE index in casts and their 3D images: A retrospective longitudinal study
Conclusions BEWE index is a suitable tool for the scoring of ETW lesions in 3D images and cast. The combination of both digital 3D records and index, can be used for the monitoring of ETW in a longitudinal approach. The higher sensibility of BEWE index when scoring 3D images might improve the early diagnosis of ETW lesions. Clinical significance The BEWE index combined with digital 3D records of oral conditions might improve the practitioner performance with respect to early diagnosis, monitoring and managing ETW.

Changes in the radicular pulp-dentine complex in healthy intact teeth and in response to deep caries or restorations: a histological and histobacteriological study
Conclusion When challenged by bacteria and bacterial by-products invading dentinal tubules, odontoblasts in the radicular pulp may undergo cell death, possibly by apoptosis. This phenomenon may be caused by progressive root-ward diffusion of bacterial by-products, cytokines or reactive oxygen species through the pulp connective tissue. Clinical Significance Although the vitality of the dental pulp in teeth with deep dentinal caries may be maintained with direct pulp capping or pulpotomy, the repair tissue that is formed resembles mineralised fibrous connective tissues more than true tubular dentine.
