- Question 1 of 10
A 62-year-old patient presents for extraction of a painful nonrestorable mandibular molar. Medical history review reveals a mechanical mitral valve and warfarin use. The patient is afebrile, has no penicillin allergy, and reports an INR of 2.7 measured yesterday. Blood pressure is 128/76 mm Hg. As the entry-level general dentist, what is the most appropriate management based on this history?
B is correct: a mechanical cardiac valve requires infective endocarditis prophylaxis for dental procedures involving gingival manipulation, and an INR of 2.7 generally supports routine extraction with local hemostasis. A is tempting, but stopping warfarin increases thromboembolic risk and requires physician direction. C addresses bleeding but misses the valve-related prophylaxis indication. D is inappropriate; clarithromycin is not standard prophylaxis here and may interact with warfarin. Document the history, INR, prophylaxis, consent, and hemostasis plan.

- Question 3 of 10
A 46-year-old patient reports 3 days of left mandibular pain. Tooth #18 has deep caries, lingering cold pain, percussion tenderness, and a periapical radiolucency. Tooth #19 has no caries but has an isolated 8-mm distal pocket with vertical bone loss. A 4-mm traumatic cheek ulcer is adjacent to a sharp cusp. The patient is afebrile with no swelling or trismus. Before definitive treatment, which action best reflects an appropriate active problem list and differential?
C is correct: the diagnosis fits history, vitality symptoms, percussion, and radiographic findings for #18, while #19 and the ulcer are separate active problems. B is tempting because vertical bone loss is significant, but extraction planning is not the first step and may require periodontal evaluation. D addresses a real mucosal problem but ignores pulpal findings. A is inappropriate without fever, spreading swelling, or systemic involvement; definitive dental treatment is needed. ASSESS all findings as active problems; INTERVENE for the urgent pulpal source; REFER for periodontal/endodontic complexity as needed; DOCUMENT diagnoses, tests, and sequencing. Review Problem Lists And Differentials — focus on matching pain source to exam and imaging.

- Question 5 of 10
A 58-year-old patient presents for a comprehensive examination. The chief complaint is a fractured maxillary premolar with spontaneous pain and percussion sensitivity. Radiographs show deep caries approaching the pulp and multiple additional carious lesions. Periodontal charting shows generalized 5–6 mm pockets with bleeding. The patient also asks about replacing missing molars with implants. Which problem-oriented treatment plan sequence is most appropriate?
Option A is correct: spontaneous pain with percussion sensitivity suggests pulpal and periapical disease; urgent pain/infection control precedes elective definitive care. Disease-control therapy reduces active caries and periodontal inflammation before prosthetic or implant decisions. D is tempting because implants may require specialist input, but elective prosthodontics before disease control is poorly sequenced. C is inappropriate because antibiotics alone do not diagnose or treat most localized odontogenic infections. A includes needed periodontal care, but combining it with elective crown preparations while deferring the urgent tooth ignores problem priority. Document diagnoses, options, risks, referrals, and patient decisions.

- Question 7 of 10
A 38-year-old patient presents for a routine dental examination. The buccal mucosa bilaterally has a diffuse, gray-white, slightly folded appearance that partially disappears when the tissue is stretched. The patient reports the appearance has been present for years without pain, ulceration, bleeding, or recent change. No removable plaques are seen. What is the most appropriate initial management?
Leukoedema is a benign normal variant, often bilateral and diffuse, with a white-gray appearance that diminishes on stretching. C is tempting because persistent white lesions can require biopsy, but symmetry, chronicity, and stretch response do not suggest dysplasia; biopsy is unnecessary unless features change. D is incorrect because candidiasis typically produces wipeable plaques or erythematous symptomatic mucosa. B is correct: reassure, document baseline findings, and observe. A is incorrect because immune-mediated mucositis usually has pain, erythema, erosions, or ulceration. ASSESS benign features; INTERVENE with education; REFER if ulceration, induration, asymmetry, or change develops; DOCUMENT location and appearance.

- Question 9 of 10
A 46-year-old patient with rheumatoid arthritis reports 8 months of dry mouth and gritty eyes. Exam shows thick, frothy saliva, erythematous mucosa under a partial denture, and new cervical root caries. There is no fever or meal-related gland swelling. As the entry-level general dentist, which initial management is most appropriate?
D is correct: xerostomia with dry eyes and autoimmune disease suggests Sjögren syndrome; the dentist should manage oral risks with fluoride, saliva substitutes/stimulants when appropriate, denture/candidiasis care, and refer for medical confirmation. B is excessive; xerostomia increases denture intolerance and caries can often be managed preventively/restoratively. C is tempting for autoimmune disease, but systemic immunosuppression is a physician/rheumatology decision, not routine dental scope. A fits acute infection or sialolithiasis with fever, purulence, or meal-related swelling, which are absent.
