Electronic Health Records (EHR) are digital versions of patients' medical histories, systematically maintained to enhance healthcare delivery, improve record-keeping, and facilitate data sharing across healthcare settings [1]. 

The integration of EHR systems has transformed the traditional method of managing patient records, replacing paper-based documentation with secure, interoperable digital platforms [2]. These systems store comprehensive patient information, including demographics, medical history, treatment plans, prescriptions, diagnostic reports, and progress notes, enabling healthcare professionals to provide evidence-based care efficiently [3]. The implementation of EHR in healthcare has shown to improve clinical workflows, reduce medical errors, and enhance patient safety by ensuring accurate and timely access to patient data [4]. Additionally, EHR systems support decision-making by integrating artificial intelligence and machine learning algorithms to assist in diagnosis, treatment planning, and risk assessment [5].

Despite these advantages, challenges such as data security, interoperability between different systems, cost of implementation, and user adaptability remain key concerns in the adoption of EHRs worldwide [6]. Regulatory frameworks, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States and the General Data Protection Regulation (GDPR) in Europe, have established standards for data protection and privacy, ensuring ethical handling of patient information [7]. As EHRs continue to evolve, their integration across various medical specialties, including dentistry, is becoming increasingly relevant.

Relevance to Dentistry

In dentistry, accurate record-keeping is crucial for diagnosis, treatment planning, and long-term patient care. The integration of EHRs in dental practice has streamlined patient management, improving communication between dental professionals, specialists, and other healthcare providers [8]. Dental EHRs store a wide range of patient information, including intraoral and extraoral images, radiographs, periodontal charts, and treatment history, facilitating comprehensive treatment planning [9]. The ability to integrate digital imaging, billing, insurance claims, and laboratory communications into a unified system has significantly enhanced efficiency in modern dental practice [10].

EHRs in dentistry also contribute to research and public health initiatives by enabling large-scale data collection and analysis of oral health trends [11]. They assist in monitoring disease patterns, assessing the impact of interventions, and improving the overall quality of dental care services [12]. Additionally, real-time access to patient data allows dentists to provide evidence-based treatments and personalized care, ensuring better treatment outcomes [13]. However, challenges such as the lack of interoperability between dental and general medical records, high implementation costs, and resistance to change among dental practitioners hinder widespread adoption [14].

Need for a Systematic Review

While the adoption of EHRs in general healthcare has been extensively studied, literature on their implementation and effectiveness in dentistry remains fragmented. Many studies focus on specific aspects, such as usability, cost-effectiveness, and security, but there is a lack of a comprehensive synthesis of findings that evaluates the overall impact of EHRs in dental practice [15]. Existing reviews often lack systematic analysis, making it difficult to draw meaningful conclusions on the benefits, challenges, and future directions of dental EHRs [16].

Additionally, technological advancements, such as cloud-based EHRs, artificial intelligence-driven diagnostics, and blockchain technology for data security, are rapidly transforming the field of digital health records [17]. A systematic review is essential to consolidate existing evidence, highlight gaps in research, and provide recommendations for improving EHR adoption in dentistry [18]. Such a review will help policymakers, researchers, and practitioners understand the current landscape and guide future innovations in digital dental record management.
