Introduction
Adverse drug reactions (ADRs) are a significant concern in medical and dental practice, affecting patient safety, treatment outcomes, and overall healthcare costs. An ADR is defined as an unintended and harmful response to a drug that occurs at normal doses used for prophylaxis, diagnosis, or therapy.1 In dentistry, ADRs can arise from the use of common medications such as antibiotics, analgesics, and local anesthetics, leading to various clinical complications.2
The prevalence of ADRs in dental practice has been reported to range from 5% to 10% among patients receiving dental care, indicating a considerable impact on clinical outcomes.2 These reactions can manifest in several ways, including allergic reactions, gastrointestinal disturbances, and systemic toxicity. For instance, antibiotics, particularly penicillins, and nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently implicated in dental ADRs.3 The management of these reactions poses challenges for dental practitioners, who must balance effective treatment with minimizing the risk of harm.
Several factors contribute to the occurrence of ADRs in dental settings. Polypharmacy, especially in elderly patients, increases the risk of drug interactions and adverse effects.4 Patient-specific factors such as age, comorbidities, and genetic predispositions further complicate the management of ADRs.4 Moreover, the lack of comprehensive patient history taking and awareness about potential drug interactions among dental practitioners exacerbates the problem.5
The underreporting of ADRs is a pervasive issue that hinders the effective monitoring and management of these reactions. Despite the availability of reporting systems like the FDA's MedWatch and the Yellow Card Scheme in the UK, their utilization in dentistry remains limited.5 Factors such as time constraints, insufficient knowledge about reporting procedures, and the perceived insignificance of certain reactions contribute to the underreporting.5
Addressing these challenges requires a multifaceted approach. Enhancing the education and training of dental practitioners on ADR detection, management, and reporting is crucial. Interdisciplinary collaboration with pharmacists and other healthcare providers can improve patient history taking and drug interaction checks, thereby reducing the risk of ADRs. Additionally, leveraging technology, such as electronic health records (EHRs) with integrated drug interaction alerts and mobile apps for easier ADR reporting, offers significant potential for improving patient safety.
This study aims to investigate the challenges faced by dentists in dealing with ADRs and identify opportunities to enhance patient care through better ADR detection, reporting, and prevention strategies.
Review of Literature
Adverse drug reactions (ADRs) in dental practice are a critical area of study due to their implications for patient safety and treatment efficacy. Understanding the prevalence, causes, types, and management strategies for ADRs can help mitigate their negative impacts. This review of literature synthesizes current knowledge on ADRs in dentistry, examining the frequency of occurrence, common drugs involved, underlying causes, reporting practices, and potential solutions for improving patient care.
Prevalence and types of ADRs in dentistry
The prevalence of ADRs in dentistry is substantial, with various studies indicating a range from 5% to 10% among patients receiving dental care (2). These reactions can manifest in multiple forms, including allergic reactions, gastrointestinal disturbances, and systemic toxicity. Allergic reactions are particularly concerning as they can lead to severe outcomes such as anaphylaxis, which is life-threatening if not managed promptly.3
Antibiotics, especially penicillins, and nonsteroidal anti-inflammatory drugs (NSAIDs) are the most frequently implicated in dental ADRs. Antibiotics are commonly prescribed to prevent or treat infections, but their widespread use has been associated with allergic reactions, gastrointestinal issues, and antibiotic resistance. NSAIDs, often used for pain management, can cause gastrointestinal disturbances, renal toxicity, and cardiovascular risks, particularly in patients with preexisting conditions.6
Causes of ADRs in dentistry
Several factors contribute to the occurrence of ADRs in dental practice. Polypharmacy, especially among elderly patients, increases the likelihood of drug interactions and adverse effects. Berdot et al.4 noted that inappropriate medication use in older adults is a significant risk factor for falls and other adverse outcomes, highlighting the importance of careful drug management in this population.
Patient-specific factors such as age, genetic predispositions, and comorbidities also play a crucial role in ADRs. For instance, genetic variations in drug-metabolizing enzymes can affect individual responses to medications, leading to adverse reactions.7 Additionally, comorbidities such as renal or hepatic impairment can alter drug metabolism and excretion, increasing the risk of toxicity.
Inadequate patient history taking and lack of awareness about potential drug interactions among dental practitioners further exacerbate the problem. A study by Gujral et al.5 found that many healthcare professionals lack sufficient knowledge about ADRs and their reporting mechanisms, contributing to underreporting and inadequate management of these reactions.
Management and Reporting of ADRs
Effective management of ADRs in dental practice requires prompt recognition, appropriate intervention, and thorough documentation. Common management strategies include discontinuing the offending drug, providing symptomatic treatment, and using alternative medications if necessary. However, the success of these strategies depends on the timely identification of ADRs, which can be challenging due to the varied and often non-specific symptoms.8
Despite the importance of reporting ADRs, underreporting remains a significant issue in dentistry. Gujral et al.5 highlighted that factors such as time constraints, insufficient knowledge about reporting procedures, and the perception that certain reactions are not severe enough to report contribute to this problem. Reporting systems like the FDA's MedWatch and the UK's Yellow Card Scheme are crucial for monitoring ADRs, yet their utilization in dental practice is limited.
Strategies for improving ADR management
Enhancing education and training for dental practitioners on ADR detection, management, and reporting is essential for improving patient safety. Continuing education programs and workshops can help keep practitioners updated on the latest guidelines and best practices. Incorporating ADR management into dental curricula can also equip future practitioners with the necessary skills and knowledge.9
Interdisciplinary collaboration with pharmacists and other healthcare providers can significantly improve the management of ADRs. Pharmacists can assist in patient history taking, drug interaction checks, and providing guidance on safe medication use. This collaborative approach can help reduce the risk of ADRs and improve overall patient care. 10
Leveraging technology offers significant potential for enhancing ADR management in dentistry. Electronic health records (EHRs) with integrated drug interaction alerts can help identify potential ADRs before they occur. Additionally, mobile apps and online reporting systems can facilitate easier and more efficient ADR reporting, thereby improving monitoring and response efforts. 11
Case studies and clinical reports
Several case studies and clinical reports have documented the occurrence and management of ADRs in dental practice, providing valuable insights into real-world challenges and solutions. For example, a case report by Kim et al.12 described a patient who developed anaphylaxis following the administration of a local anesthetic. The prompt recognition and management of the reaction, including discontinuation of the drug and administration of epinephrine, were critical in ensuring the patient's safety.
Another case study by Moore et al.6 highlighted the importance of thorough patient history taking in preventing ADRs. The study described a patient with a known allergy to penicillin who was inadvertently prescribed amoxicillin, leading to a severe allergic reaction. This case underscores the need for meticulous documentation and verification of patient allergies and medication histories.
Ongoing research is needed to further understand the mechanisms underlying ADRs and develop more effective strategies for their prevention and management. Pharmacogenomics, the study of how genetic variations affect drug responses, holds promise for personalized medicine approaches in dentistry. By tailoring drug therapies based on individual genetic profiles, it may be possible to reduce the risk of ADRs and optimize treatment outcomes.7
Additionally, more robust reporting systems and databases are needed to capture and analyze data on ADRs in dentistry. Such systems can help identify trends, risk factors, and potential solutions for improving patient safety. Collaborative research efforts involving dental practitioners, pharmacologists, and other healthcare professionals can drive the development of evidence-based guidelines and best practices for ADR management.11

Data collected from 130 dental practitioners revealed that 84.6% encountered ADRs in the past year, with antibiotics (53.8%) and NSAIDs (30.8%) being the most commonly implicated drugs. Allergic reactions were the most frequently reported ADRs (46.2%), followed by gastrointestinal issues (23.1%) and systemic toxicity (15.4%). The primary management strategy was discontinuing the offending drug (53.8%), while barriers to ADR reporting included lack of time (46.2%) and insufficient knowledge (30.8%).
The discussion highlighted the high prevalence of ADRs and the significant role of antibiotics and NSAIDs, aligning with existing literature. The frequent occurrence of allergic reactions underscores the need for vigilant patient history taking. Management practices indicate gaps in knowledge and resources, emphasizing the need for additional training. The identified barriers to ADR reporting point to the necessity for improved education and streamlined reporting systems. A significant association between years of practice and reporting practices suggests that more experienced practitioners are more likely to report ADRs, indicating a need for targeted training for less experienced practitioners. Recommendations include enhancing education, promoting interdisciplinary collaboration, utilizing technology, and educating patients to improve ADR management and reporting in dental practice.
