Explanation:
The internal line angles of cavity preparations for composite resin or amalgam restorations should be rounded to reduce stress concentration, which helps prevent fracture of the restoration and tooth structure.
Explanation:
The geographic tongue presents as multiple smooth, irregular zones of erythema (red patches) surrounded by a white border on the dorsal and lateral ventral surfaces of the tongue. It's a benign condition characterized by transient inflammatory changes in the surface of the tongue.
Explanation:
Flaps in minor oral surgery should have releasing incisions to enhance their mobility and facilitate tension-free closure, which promotes optimal healing and reduces the risk of complications such as flap necrosis.
Explanation:
A dental implant analogue is used in making a master cast, which is a precise replica of the patient's oral structures, including the dental implants. This master cast is essential for fabricating prosthetic restorations that fit accurately onto dental implants.
Explanation:
Naproxene is a non-steroidal anti-inflammatory drug (NSAID) that is effective for managing dental pain associated with inflammation. It helps reduce pain and inflammation by inhibiting prostaglandin synthesis, making it a suitable choice for dental pain relief.
Explanation:
An acetaminophen overdose is most likely to result in hepatotoxicity, which refers to liver damage or toxicity. Acetaminophen is primarily metabolized in the liver, and an overdose can overwhelm the liver's ability to process it, leading to liver damage or failure.
Explanation:
Topical corticosteroids are the most appropriate initial management for multiple aphthous ulcers on the labial mucosa. They help reduce inflammation, pain, and healing time associated with aphthous ulcers.
Explanation:
The most appropriate management for recurrent pericoronitis of a mandibular third molar with inadequate arch space is the extraction of the tooth. Removing the third molar eliminates the source of infection and prevents future episodes of pericoronitis.
Explanation:
Resin-modified glass ionomer cement is commonly used for the cementation of zirconia-based crowns due to its good adhesion to both zirconia and tooth structure, as well as its favorable physical properties and biocompatibility.
Explanation:
Bupivacaine is a long-acting local anesthetic that provides prolonged pain relief, making it suitable for procedures requiring extended duration of anesthesia, such as a pulpectomy for tooth 3.6. The addition of epinephrine helps to prolong the anesthetic effect and minimize bleeding.
Explanation:
The maximum daily analgesic dose of ibuprofen for a healthy adult is typically 2,400 mg, taken in divided doses throughout the day. Exceeding this dosage can increase the risk of adverse effects such as gastrointestinal irritation, renal impairment, and cardiovascular events.
