Question 1: Oral Pathology & Radiology
A panoramic radiograph of an asymptomatic 18-year-old male reveals a large, well-defined, multilocular radiolucency in the posterior mandible, causing displacement of the third molar. The lesion has a “soap bubble” appearance. What is the most likely diagnosis?
- Dentigerous Cyst
- Odontogenic Keratocyst (OKC)
- Ameloblastoma
- Radicular Cyst
Correct Answer: C (Ameloblastoma)
Rationale: The key features described are classic for an ameloblastoma. It is a benign but locally aggressive odontogenic tumor. The classic radiographic presentation is a multilocular (“soap bubble” or “honeycomb”) radiolucency, most commonly found in the posterior mandible of young adults. It often causes significant expansion of the jaw and displacement of teeth, as described in the scenario. While other lesions can be multilocular, this combination of features is most indicative of an ameloblastoma.
Why other options are incorrect:
A: A dentigerous cyst is a unilocular radiolucency that is always associated with the crown of an unerupted tooth.
B: An OKC can be multilocular and is known for its high recurrence rate, but it typically grows along the bone without causing significant expansion, unlike an ameloblastoma.
D: A radicular cyst is the most common odontogenic cyst, but it is always associated with the apex of a non-vital tooth and presents as a unilocular radiolucency.
Question 2: Prosthodontics
When designing a mandibular removable partial denture for a Kennedy Class I arch (bilateral free-end edentulous areas), what is the primary function of the indirect retainer?
- To provide bracing against lateral forces.
- To prevent the denture from moving towards the tissue.
- To prevent the distal extension base from lifting away from the tissue.
- To retain the denture against dislodging forces during mastication.
Correct Answer: C
Rationale: This question tests a fundamental principle of RPD design for distal extension cases. The indirect retainer is a component that rests on a tooth surface (usually a cingulum or mesial occlusal rest) anterior to the fulcrum line. The fulcrum line is an imaginary line connecting the most posterior rests. When sticky foods lift the distal extension base, the denture rotates around this fulcrum line. The indirect retainer engages on the opposite side of the fulcrum, preventing this rotational lifting movement and keeping the denture base seated against the tissue.
Why other options are incorrect:
A: Bracing is provided by components like guide plates and major connectors.
B: Preventing movement towards the tissue is the function of the occlusal rests.
D: Retention against vertical dislodgement is the primary function of the direct retainers (clasps).
Question 3: Periodontics
A patient with generalized chronic periodontitis is undergoing non-surgical periodontal therapy. Which of the following microorganisms is most strongly associated with this condition and is a primary target of the therapy?
- Streptococcus mutans
- Actinomyces viscosus
- Lactobacillus acidophilus
- Porphyromonas gingivalis
Correct Answer: D (Porphyromonas gingivalis)
Rationale: Chronic periodontitis is associated with a specific group of gram-negative anaerobic bacteria. Porphyromonas gingivalis, along with Tannerella forsythia and Treponema denticola, form the “red complex,” which are strongly implicated as the primary pathogens in the progression of periodontal disease. P. gingivalis is a keystone pathogen that orchestrates the dysbiotic inflammatory response leading to pocket formation and bone loss. Therefore, scaling and root planing aims to disrupt the biofilm and reduce the bacterial load of these specific pathogens.
Why other options are incorrect:
A & C: Streptococcus mutans and Lactobacillus acidophilus are gram-positive bacteria that are primary etiologic agents of dental caries, not periodontitis.
B: Actinomyces species are early colonizers in plaque formation but are not considered primary pathogens in chronic periodontitis.
Frequently Asked Questions (FAQs) for the SDLE
The SCFHS uses a scaled scoring system. The SDLE is scored on a scale out of 800, and the official passing score is 500. This is a standardized score, not a percentage, ensuring a consistent level of difficulty across different exam forms.
Candidates are typically allowed four attempts to pass the SDLE. There are specific regulations regarding the time between attempts, so it is essential to consult the official SCFHS website for the most current policies.
Both are comprehensive, case-based exams for general dentists. The core clinical content is very similar, as both are based on international evidence-based standards. The main differences lie in the exact format (number of questions, timing) and the administrative body. A dentist who is well-prepared for the INBDE would have a strong foundation for the SDLE. For more on international standards, you can refer to bodies like the American Dental Association (ADA).
No, the SDLE is a clinical competency exam based on international dental science and best practices. It does not test knowledge of local laws, public health statistics, or administrative policies.
The Primary Source Verification (PSV) by DataFlow is a mandatory credentialing step. You can typically start the process before or after the exam, but you must have a positive DataFlow report before the SCFHS will issue your final Saudi SCFHS license for practice.
The consensus among successful candidates is that the most critical study tool is a high-quality, comprehensive question bank (QBank) that focuses on case-based scenarios and provides detailed rationales. This active learning approach is superior to passive reading for mastering clinical reasoning.
A focused, dedicated study period of 4 to 6 months is generally recommended for most dentists to thoroughly cover the extensive syllabus and complete a large QBank with proper review.
No, the exam uses only generic names for all drugs and generic classifications for all materials (e.g., “glass ionomer cement,” “polyvinyl siloxane”).
Time management is crucial. Use the scheduled break between the two sections to rest and refocus. During each section, aim to pace yourself at just over one minute per question. Use the “flag” feature for questions you are unsure about and return to them at the end of the section if you have time. Do not get stuck on a single difficult question.
Supplement your QBank practice with a good oral radiology textbook or atlas (e.g., White and Pharoah’s Oral Radiology). Practice a systematic approach: look at the teeth, then the periodontal structures, then the surrounding bone. This ensures you don’t miss important findings.
