Light-Induced Fluorescence-based Device and Hybrid Mobile Application for Oral Hygiene Management at Home: Feasibility Study
ABSTRACT
Background:
Dental diseases can be prevented through the management of dental plaques. The dental plaque is identified by the light-induced fluorescence (LIF) technique that emits light at 405 nm. The LIF technique is more convenient than the commercial technique using the disclosing agent, but the result may vary for each individual as it still requires visual identification.
Objective:
The objective of this study was to develop a LIF system that allows easy identification of dental plaque at home and to confirm its feasibility.
Methods:
We developed a LIF-based system consisting of a device that can visually identify dental plaques and a mobile application that displays the location and area of dental plaques on oral images. The mobile application is programmed to automatically determine the location and distribution of dental plaques through a deep learning-based algorithm and present the results to the user as time series data. In addition, the mobile application was built with the convergence of naive application and web application so that the algorithm is executed on the cloud server to efficiently distribute the computing resources.
Results:
The location and distribution of user’s dental plaques could be identified via the hand-held LIF device or the mobile application. The color correction filter of the device was developed through color mixing technique. The mobile application was built as a hybrid application combining the functionalities of native application and web application. Through the scrollable WebView on the mobile application, changes in the time series of dental plaque could be confirmed. The algorithm for dental plaque detection was implemented to run on the Amazon Web Services for object detection by Single Shot MultiBox Detector and instance segmentation by Mask R-CNN.
Conclusions:
This paper showed that this system can be used as a home oral care product to timely identify and manage the dental plaque. In the future, it is expected to significantly reduce the social costs associated with dental diseases through using these products.
