Iran Dental Specialty Board - Periodontics study guide
Iran Dental Specialty Board - Periodontics · Work through your exam, one topic at a time.
The Iranian dental specialty board in periodontics (بورد تخصصی دندانپزشکی – دورهشناسی) is the national credential that marks completion of postgraduate specialist training in periodontics and admits the holder to sit for specialist-level practice and academic posts in Iran. It is aimed at dentists who have finished an accredited Iranian periodontics residency, and at graduates of comparable programs seeking recognition. The Iran Dental Specialty Board - Periodontics study guide has 10 sections and about 2,920 words.
01Periodontal Anatomy, Histology, and Physiology
This domain tests whether histologic fact can be turned into a clinical decision: where the attachment truly lies, what a probing depth measures, and which structures return after surgery. Gingiva comprises marginal (free) gingiva, attached gingiva and interdental papillae; the free gingival groove and mucogingival junction are the surface landmarks.
318 words, about 2 min02Etiology and Pathogenesis of Periodontal Disease
Questions here test the biofilm–host interaction, the evolution of plaque hypotheses, and the risk factors that shift a gingivitis case into progressive periodontitis. Plaque is a structured multi-species biofilm; the ecologic plaque hypothesis (Marsh) frames disease as dysbiosis driven by environmental change, not by a single pathogen.
303 words, about 2 min03Periodontal Diagnosis and Clinical Assessment
This domain tests systematic charting, the 2017 AAP/EFP staging and grading system, and radiographic interpretation. PD, CAL, recession, BOP, plaque indices (O'Leary, Silness–Löe), mobility (Miller 0–3), furcation (Glickman I–IV, Hamp), mucogingival deformities.
265 words, about 1 min04Non-Surgical Periodontal Therapy
The exam tests debridement technique, adjunct selection, and the discipline of reevaluation before surgery. SRP removes biofilm and calculus; it cannot regenerate lost attachment.
296 words, about 1 min05Periodontal Surgical Therapy
Tested here: flap design selection, resective versus regenerative intent, and the contraindications that matter more than the technique. Flap access: modified Widman (tissue conservation, open debridement), papilla-preservation incisions (best for regeneration and esthetics), apically positioned flap (pocket elimination plus keratinized tissue), distal wedge (terminal molars).
287 words, about 1 min06Regenerative and Reconstructive Periodontics
The exam separates what regenerates predictably from what merely fills a space, and tests defect selection. Guided tissue regeneration (Nyman, Karring, Gottlow): a barrier excludes epithelium and gingival connective tissue so PDL and bone cells repopulate the defect.
292 words, about 1 min07Implantology and Peri-Implant Disease
This domain tests surgical positioning, loading decisions, and the mucositis/peri-implantitis distinction with its 2018 case definitions. Osseointegration: direct bone-to-implant contact without intervening soft tissue; primary stability is mechanical, secondary stability biologic (bone remodeling).
287 words, about 1 min08Periodontal Medicine and Systemic Interactions
The exam tests bidirectional relationships and the medication/medical-history decisions that change periodontal care. Diabetes: hyperglycemia amplifies inflammation and bone loss; periodontitis worsens glycemic control.
285 words, about 1 min09Multidisciplinary Treatment Planning
Tested here is sequencing: the exam wants a defensible order of care and an honest prognosis for each tooth. Sequence: emergency care → phase I disease control (oral hygiene, SRP, caries, endodontics, extraction of hopeless teeth) → reevaluation → phase II (surgery, regeneration, implants) → restorative/prosthetic → maintenance.
297 words, about 1 min10Research Methodology, Evidence-Based Practice, and Ethics
This section tests appraisal skills and professional conduct - reading a paper's design, numbers and integrity correctly. Hierarchy: systematic reviews/meta-analyses of RCTs RCTs cohort case-control cross-sectional case reports.
