Tramadol is an effective alternative local anaesthetic (LA) agent available in dentistry. This review aims to help guide practice by providing clinicians with relevant data regarding adverse effects (AE) associated with locally administered tramadol in the oral environment. A systematic search of three electronic databases was performed to identify relevant studies reporting AE associated with locally administered tramadol in the oral setting. Selected studies were reviewed and included based on inclusion and exclusion criteria. Data collected included: publication year, study design, participant numbers, adverse effects and follow-up duration. Fifteen articles were included comprising of 547 tramadol participants across eight exodontia and seven non-exodontia studies. Thirty-eight associated AE were reported. Nausea was the most commonly reported (4.6%), followed by dizziness (1.3%), vomiting (0.7%) and local erythema (0.4%). No other AE were reported. The prevalence of total AE was similar in ≥ 50 mg tramadol doses (7.2-7.3%); however the total affected number is not dose dependent. The prevalence of AE and affected participants was less when tramadol was used as a sole LA rather than as an adjunct (5.6% vs. 7.9% and 3.4-5.6% vs. 6.3%, respectively). Thus, tramadol is a safe LA agent with a low prevalence of AE when administered in the dental setting.
