Developmental Progression of Dental Image-Analysis Applications: From iOralCam to iOralForens and OralCam—A Comparative Review

This review examines the developmental progression of three dental image-analysis applications developed by Tele-Optic Services Pty Ltd: iOralCam, iOralForens, and OralCam. The review evaluates their chronology, platform architecture, image-processing functions, standardization approaches, quantitative analysis, and potential clinical, research, and forensic applications. iOralCam established smartphone-based optical, molecular-related and pixel-processing analysis; iOralForens subsequently introduced a simplified forensic workflow for comparative ante-mortem (AM) and post-mortem (PM) dental image assessment; and OralCam expanded these capabilities into a broader cross-platform system incorporating colour and lighting processing, tooth-shade analysis, and dental image-record functions. For methodological illustration, three 132-observation analytical pathways were considered, including 132 paired AM–PM observations for iOralForens, organized into 11 analytical groups. Simulated datasets were used where empirical measurements were not available. Data were organized and analysed using Microsoft Excel, applying descriptive statistical methods including means, standard deviations, minimum and maximum values, percentage discrepancy, and comparative group summaries. For AM–PM comparison, percentage discrepancy was calculated as |AM−PM|/AM × 100. The simulated iOralForens analysis produced mean group-level discrepancies of approximately 2.42% for LuminosityID% and 2.46% for ColourID%. These findings illustrate the application of quantitative image comparison and reproducibility assessment but do not represent independent clinical or forensic validation. The review demonstrates a progressive transition from specialized optical and molecular-related analysis to forensic image comparison and subsequently to a broader cross-platform dental imaging environment. Standardized image acquisition, reproducibility assessment, independent validation, and professional interpretation remain essential for future clinical and forensic implementation.
