Philadelphia: Lippincott Williams & Wilkins 2013.īoardVitals NBDE II Question Bank has hundreds of questions targeted to the National Board Dental Exam 2. In: Barash PG, Cullen BF, Stoelting RK, Cahalan MK, Stock MC, Ortega R. Reference: Dahan A, Niesters M, Olofsen E, Smith T, Overdyk F. John’s wort is a CYP3A inducer, and would be less likely to result in decreased metabolism of hepatically-modified opioids.ĭ) Rifampicin is a CYP3A inducer, and would be less likely to result in decreased metabolism of hepatically-modified opioids.Į) Diltiazem is a CYP3A inhibitor, and would be the most likely drug in the given selection to result in decreased metabolism of hepatically-modified opioids. It is important to be aware of common inducers and inhibitors of the cytochrome system, which can decrease and increase duration of action of opioids, respectively.Ī) Carbamazepine is a CYP3A inducer, and would be less likely to result in decreased metabolism of hepatically-modified opioids.ī) Phenytoin is a CYP3A inducer, and would be less likely to result in decreased metabolism of hepatically-modified opioids.Ĭ) St. Some metabolites may have active analgesic activity, similar to their parent drug, and in some situations, with added side effects and toxicities. These reactions produce metabolites that are excreted renally or via the biliary tract. Phase II reactions involve conjugation of the drug to a specific substrate. Phase I reactions involve oxidative and reductive reactions, and are orchestrated by the cytochrome P450 enzyme system. Most opioids undergo hepatic metabolism, via either phase I or phase II reactions. Which of the following drugs is most likely to result in decreased metabolism of opioids that undergo hepatic metabolism? It is asymptomatic, but does NOT generally involve radiographic changes at the apex. This polyp of tissue is indicative of pulpitis in that tooth. This process then creates an opening from the pulp to the oral cavity and the pulp tissue will almost balloon into the opening. Pulp polyps (d) are most often found in young teeth that have had the carious process destroy some of the crown of the tooth. Generally in this condition, radiographic bone changes have not yet occurred because the pulp has not yet become necrotic. Irreversible pulpitis (c) presents with spontaneous, intermittent pain and involved vital pulp tissue slowly dying. The radiolucency would proceed in a coronal to apical direction, rather than from the apex outward. Our practice tests simulate the actual testing experiences by covering the required competencies and incorporating content and the application of skills necessary for you to be ready for. This type of abscess would be visible radiographically, but the focus would be on degeneration of bone at the coronal half of the tooth. We offer 4 NBDE subjects with 20 different exams utilizing 2,000 unique questions specifically designed to help you pass your NBDE certification exam. Another term linked with this would be acute apical abscess.Ĭhronic periodontal abscess (b) is a condition of the periodontium, not the pulp. This condition would result in painful symptoms and sensitivity on biting. When obvious periapical radiolucencies are found on radiographic examination, and there is no recollection of symptoms, the most likely diagnosis is that of chronic apical periodontitis.Īcute suppurative periodontitis (a) involves quick onset of necrotic outflow from the tooth. The necrotic pulp can then exude from the roots and slowly create asymptomatic abscesses. Over time, heavily restored teeth can develop asymptomatic pulpitis leading to pulpal necrosis. What is the most likely diagnosis?Īnswer: E. The patient does not recall any past symptoms. Radiographically, the heavily restored lower right first molar shows apical radiolucencies of both the mesial and distal roots. Sample NBDE II Practice Questions Question 1. Endodontics QID 35150Ī patient presents for routine examination. Free to download, with an in-app purchase.These are free sample practice questions taken from the BoardVitals NBDE II Question Bank. $50. While the ADAnet site doesn’t offer many questions, it is good to get used to the style of the questions that will be on the exam. Starts at $69/month for NBDE I. 1000 questions with detailed explanations used by more institutions than any other NBDE Question Bank. Here is a set of resources that we personally reviewed. DO THEM! Then move onto other question banks. The ASDA sells released examinations with actual questions from the NBDE. Pathology is one of the harder sections for many students, so make sure to allocate sufficient study time there. The questions on the actual NBDE range in difficulty, so make sure to practice on some of the faster questions, as well as the more in-depth Occlusion questions. Take the time to review the material (flashcards and books to cover the basics) and then try to answer as many questions as possible. There is a strong correlation between the number of NBDE practice questions taken and performance on the NBDE exams. Here are the four categories that are on the exam: The NBDE I exam is a review of the many of the basic science fundamentals as well as introductory concepts in Dental Anatomy.
