Misdiagnosis of periodontal disease across Europe, the Middle East, and Asia is linked to the costly and time-intensive training required for dental specialization. In Europe, the UK’s periodontics residency programs cost around £30,000 annually, with training spanning 3 years. In the Middle East, Saudi Arabia’s residency programs charge up to SAR 180,000 annually over 3-4 years (riyadh.edu.sa), while the UAE’s Mohammed Bin Rashid University costs AED 185,000 annually for a 3-year periodontics program. In Asia, India’s Master of Dental Surgery in Periodontology averages ₹600,000 ($7,200) over 3 years (manipal.edu), and Japan’s postgraduate dental programs can cost up to ¥5 million ($33,000) annually. These financial and time barriers significantly limit access to advanced training, contributing to diagnostic inaccuracies and elevated healthcare burdens.
