✅ Introduction
Odontogenic pain is frequently associated with inflammation, tissue injury, or post-operative trauma. The rational prescription of analgesics requires a solid understanding of their pharmacological properties. Diclofenac, ibuprofen, and acetaminophen are widely used in dentistry, yet their indications and limitations vary significantly. This article analyzes their mechanisms of action, pharmacological behavior, clinical indications, precautions, and comparative effectiveness in dental practice.

📌 Recommended Article :

Dental Article 🔽 Pediatric Dental Emergencies: How to Face an Urgent Consultation ... Pediatric dental emergencies are critical situations requiring prompt diagnosis, calm communication, and effective intervention to relieve pain, prevent complications, and protect developing teeth.

✅ Mechanism of Action

➤ Ibuprofen
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that non-selectively inhibits cyclooxygenase enzymes (COX-1 and COX-2), reducing prostaglandin synthesis. This results in analgesic, anti-inflammatory, and antipyretic effects.

➤ Diclofenac
Diclofenac is an NSAID with potent inhibition of COX-2 and partial inhibition of COX-1, leading to a strong anti-inflammatory and analgesic effect. It also modulates lipoxygenase pathways and reduces arachidonic acid release.

➤ Acetaminophen (Paracetamol)
Acetaminophen acts primarily at the central nervous system level, inhibiting prostaglandin synthesis in the brain. Unlike NSAIDs, it has minimal peripheral anti-inflammatory activity, but effective analgesic and antipyretic properties.

✅ Can These Analgesics Be Combined in Dental Practice?
The combined use of analgesics in dentistry may be appropriate only when based on pharmacological complementarity and patient safety.
Ibuprofen and acetaminophen can be safely combined, as they have different mechanisms of action and act at distinct sites (peripheral vs. central). This combination has demonstrated superior analgesic efficacy compared to either drug alone, particularly in acute postoperative dental pain, without significantly increasing adverse effects when used at therapeutic doses.
In contrast, diclofenac should not be combined with other NSAIDs such as ibuprofen, due to overlapping mechanisms of action. Concomitant use increases the risk of gastrointestinal bleeding, renal toxicity, and cardiovascular adverse events, without providing additional analgesic benefit.
Acetaminophen may be combined with diclofenac in selected cases; however, this combination should be used cautiously and for short durations, especially in patients with hepatic risk factors.

Key clinical principles:
▪️ Ibuprofen + Acetaminophen: recommended and evidence-based
▪️ Ibuprofen + diclofenac: contraindicated
▪️ Diclofenac + Acetaminophen: possible, but with strict clinical judgment

📌 Recommended Article :

Dental Article 🔽 Pediatric Dental Emergencies: How to Face an Urgent Consultation ... Pediatric dental emergencies are critical situations requiring prompt diagnosis, calm communication, and effective intervention to relieve pain, prevent complications, and protect developing teeth.

✅ Precautions and Safety Considerations

➤ Ibuprofen: gastrointestinal irritation, renal impairment risk, contraindicated in advanced kidney disease.
➤ Diclofenac: higher cardiovascular and gastrointestinal risk with prolonged use.
➤ Acetaminophen: risk of hepatotoxicity in overdose or chronic use, especially in patients with liver disease.

✅ Which Analgesic Has the Broadest Therapeutic Scope?
Ibuprofen has the widest therapeutic applicability in dentistry, due to its balanced analgesic and anti-inflammatory effects, favorable safety profile, and extensive clinical evidence. Diclofenac is more potent but carries higher systemic risks, while acetaminophen is best suited for patients where NSAIDs are contraindicated.
