Purpose: The variations in interproximal contact areas have been categorised open (O), point (X), straight (I), and curved contact (S). This is based on their shapes and termed as OXIS classification. The interactive OXIS calibration website was developed to assist researchers seeking appropriate knowledge, minimise the overload of material, optimise efficiency in calibration and, to provide repositories for clinicians, healthcare workers, and policymakers.
Methods: The website was developed in two phases. The first phase of development included expert group discussion, Focus Group Discussion (FGD), and the implementation of FGD recommendations. The second phase emphasised registration and development of the interactive web portal on OXIS classification. The developed website was subjected to user experience testing, functional testing, performance testing, security testing, device, platform testing, and then hosted. Calibrated students and faculties evaluated it with the help of Suitability Assessment of Materials (SAM) and System Usability Scale (SUS). Finally, after amendments, the website was evaluated by non-calibrated researchers and multidisciplinary experts.
Results: The total agreement was 74% for overall SAM category. Pooled mean total score of SUS was 52.7 (SD 7.17; range 45-67.5), indicating an average score.
Conclusion: The content of the developed website has been evaluated as "satisfactory" and its technical quality as "of higher standards".
