Question
A 22-year old female presents with pain and inflammation due topericoronitis around a partially erupted lower 3rd molar tooth. Her dentalpractitioner prescribes paracetamol 500 mg to be taken as required.(i) What is the dental approach to treat pericoronitis?(ii) Give your reason(s), with specific reference to the mechanism ofdrug action, why you consider the drug and dosing regimen tobe appropriate or inappropriate?(iii) What drug therapy would you initiate if you consider the above isinappropriate?
Solution
(i) The dental approach to treat pericoronitis typically involves a few steps. Initially, the dentist may clean the area around the tooth to remove any food particles or plaque that may be contributing to the infection. This is often followed by prescribing antibiotics to fight the infection. In severe cases, or if the pericoronitis keeps coming back, the dentist may recommend a procedure to remove the gum tissue over the tooth (operculectomy) or even extraction of the tooth itself.
(ii) Paracetamol (also known as acetaminophen) is a common over-the-counter medication used to relieve pain and reduce fever. It works by inhibiting the production of prostaglandins, substances in the body that cause pain and inflammation. The dosage of 500 mg as required seems appropriate for managing the pain associated with pericoronitis. However, paracetamol does not have any anti-inflammatory properties, nor does it fight the infection causing the pericoronitis. Therefore, while it may help with symptom management, it does not treat the underlying cause.
(iii) If the paracetamol is deemed inappropriate due to its lack of anti-inflammatory and antibacterial properties, a more suitable medication might be a non-steroidal anti-inflammatory drug (NSAID) like ibuprofen, which can reduce both pain and inflammation. Additionally, an antibiotic such as amoxicillin could be prescribed to fight the bacterial infection causing the pericoronitis. As always, the specific drug therapy should be tailored to the individual patient's needs and medical history.
