Appointment Synchronization: The dental clinic system synchronizes appointment data across different platforms or devices. This ensures that all appointments made by patients are updated and accessible in real$-$time. For example, if a patient schedules an appointment through the clinic's website, the system will synchronize this information with the clinic's internal scheduling software, allowing dentists and staff to view and manage the appointment details seamlessly.

Patient Record Synchronization: The dental clinic system synchronizes patient records across various modules or databases within the system. This ensures that patient information, such as medical history, treatment plans, and billing details, remains consistent and up$-$to$-$date across different components of the system. For instance, when a dentist updates a patient's treatment plan in the electronic health record module, the system synchronizes this information with the billing module, ensuring accurate invoicing and financial records.
