In today’s fast-paced world, patients are seeking more efficient and convenient ways to schedule appointments with healthcare providers. With the increasing demand for convenient and efficient healthcare services, online appointment booking systems have become essential for dental practices. In response to this need, we have designed and implemented an online dental appointment website using ASP .Net and SQL Server. This paper discusses the features of online appointment booking systems, how they can enhance the overall experience for patients and dental clinics, and the website's design and implementation, including the database schema, user interface, and server-side scripting. The website allows patients to schedule appointments, view their appointment history, view and download their medical reports and update their personal information. Dentists can view their upcoming appointments, update their schedules, generate the patient’s medical reports and manage their patient database.
