In dental practice, the use of pharmaceuticals, especially antimicrobials and analgesics, is an important part of treating infections and controlling postoperative pain. Regarding dental pharmacology and its indications, analyze the following propositions:

I.Prophylactic antibiotics should be routinely used in all invasive dental procedures to prevent infections, even in patients without systemic risk factors.
II.Analgesics such as paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are commonly prescribed for pain management after dental extractions.
III.Prolonged and indiscriminate use of antimicrobials in dentistry can lead to the development of bacterial resistance, making infections more difficult to treat in the future.

Assinale a alternativa correta:

Cone-beam computed tomography (CBCT) is an advanced imaging technique increasingly used in dental practice due to its ability to provide detailed information on orofacial structures. Regarding the use of CBCT in dentistry, select the correct alternative:

Orthognathic surgery aims not only at aesthetic improvement but also at functional enhancement, requiring detailed planning that involves orthodontic diagnosis and advanced radiographic examinations. Regarding the principles that guide this surgery, analyze the following statements:

I.In patients with mandibular retrognathia, mandibular advancement performed during orthognathic surgery can improve not only occlusion but also the patency of the upper airways, helping in the treatment of obstructive sleep apnea.
II.The use of computed tomography and three-dimensional digital planning is crucial for the accuracy of bone cuts and for predicting final results in orthognathic surgery, being the preferred method for detailed predictions of postoperative occlusion and facial profile. 
III.After orthognathic surgery, the use of fixation devices such as plates and screws is always temporary, and they must be removed after complete bone healing to avoid complications.
