INI-CET MDS study guide
INI-CET MDS · Work through your exam, one topic at a time.
INI-CET MDS is the combined entrance test used by India's Institutes of National Importance - AIIMS campuses, PGIMER Chandigarh, JIPMER and comparable institutes - to rank dental graduates for admission to Master of Dental Surgery programmes. It is a postgraduate admission examination, not a licensing or specialty-board credential: your score decides where, and in which specialty, you can train. The INI-CET MDS study guide has 14 sections and about 5,217 words.
01Dental Anatomy: Numbering, Morphology and Clinical Correlates
Dental Anatomy in INI-CET tests precise morphology, tooth identification across numbering systems, eruption chronology and the clinical consequences of that anatomy - access cavity shape, canal numbers, contact and embrasure design. FDI system: two digits, the first is the quadrant (1–4 permanent, 5–8 primary), the second the tooth position 1–8 counting from the midline.
404 words, about 2 min02Oral Histology and Oral Embryology: Tissues and Their Origins
This domain tests the composition and ultrastructure of dental hard and soft tissues, plus the embryological derivation of oral structures - both are high-yield because they underpin pathology and clinical behaviour. Enamel: about 96% inorganic by weight, formed by ameloblasts; rod direction alternates to form Hunter–Schreger bands; hypocalcified lamellae, tufts and spindles are the classic structural defects; acellular and non-renewable once formed.
396 words, about 2 min03Oral Pathology and Oral Microbiology: Cysts, Tumours and Biofilm Pathogens
INI-CET tests pattern recognition of odontogenic lesions, the biology of potentially malignant disorders, and the specific organisms driving caries and periodontal disease. Radicular cyst is the most common odontogenic cyst, always associated with a non-vital tooth; dentigerous cyst is second and encloses the crown of an impacted tooth; odontogenic keratocyst is characterised by parakeratinised corrugated epithelium with palisaded, hyperchromatic basal cells, satellite cysts and PTCH1 mutation, and is associated with naevoid basal cell carcinoma syndrome.
382 words, about 2 min04Oral Medicine, Oral Radiology and Oral Diagnosis
This domain tests vesiculobullous disease, chronic ulceration, orofacial pain and the radiographic patterns that narrow a differential diagnosis. Recurrent aphthous stomatitis: minor (commonest, heals without scar), major (larger, scarring), herpetiform (multiple small coalescing ulcers).
373 words, about 2 min05Conservative Dentistry and Endodontics
This domain tests caries management philosophy, adhesive dentistry mechanics, and the biological and technical steps of root canal treatment. Critical pH is about 5.5 for enamel and 6.2–6.5 for dentin/cementum; demineralisation is reversible until cavitation, which is the basis of minimal intervention and remineralisation with fluoride, CPP-ACP or silver diamine fluoride.
384 words, about 2 min06Periodontology and Implantology: Classification and Maintenance
This domain tests the 2017 World Workshop classification, the microbial and host basis of periodontal destruction, nonsurgical and surgical therapy, and implant maintenance. Staging describes severity and complexity of management: Stage I CAL 1–2 mm, Stage II CAL 3–4 mm, Stage III CAL ≥5 mm with probing depth ≥6 mm and up to four teeth lost, Stage IV with five or more teeth lost plus complex rehabilitation needs.
376 words, about 2 min07Oral and Maxillofacial Surgery: Anaesthesia, Impactions and Trauma
This domain tests local anaesthetic pharmacology and technique, third molar assessment, odontogenic infection management, maxillofacial trauma patterns and medically complex surgery. Lidocaine 2% = 20 mg/mL; a 1.8 mL cartridge holds 36 mg.
353 words, about 2 min08Prosthodontics and Crown & Bridge: Design Decisions
This domain tests complete denture sequence and occlusion, removable partial denture classification and design, fixed prosthodontic principles, and implant-supported prostheses. Complete denture sequence: primary impression in stock tray, border moulding with modelling compound, wash impression, record bases with wax rims, jaw relation records, try-in, processing, insertion and review.
370 words, about 2 min09Orthodontics and Dentofacial Orthopaedics: Growth, Ceph and Biomechanics
This domain tests cephalometric interpretation, Angle's classification, the biology of tooth movement, anchorage and appliance selection, and retention. Cephalometric norms: SNA 82° ± 2, SNB 80° ± 2, ANB 2° ± 2.
363 words, about 2 min10Pediatric and Preventive Dentistry: Fluorides, Space and Trauma
This domain tests early childhood caries, fluoride vehicles and their concentrations, pulp therapy in primary teeth, space maintenance, behaviour guidance and paediatric trauma. Early childhood caries affects children up to 71 months, typically maxillary incisors first with mandibular incisors spared because of salivary protection.
355 words, about 2 min11Public Health Dentistry: Indices, Epidemiology and Prevention
This domain tests oral health indices, study design and measures of association, screening test performance, levels of prevention and community fluoride policy. DMFT/dmft counts decayed, missing and filled teeth; it is an irreversible index of past and present caries experience.
332 words, about 2 min12General Medicine: Medical Risk in Dental Practice
This domain tests how systemic disease modifies dental treatment planning: glycaemic control, hypertension, cardiac risk and endocarditis prophylaxis, anticoagulation, and endocrine emergencies. Diabetes: HbA1c below 7% indicates good control; poorly controlled diabetes impairs healing and worsens periodontitis.
340 words, about 2 min13General Surgery: Asepsis, Wounds, Biopsy and Neck Pathology
This domain tests surgical principles applied to the head and neck: sterilisation, wound healing, suture choice, biopsy technique, fluid and shock management, and salivary gland and neck swellings. Autoclave sterilisation at 121 °C, 15 psi for 15 minutes; chemical indicators and biological spore testing verify function.
387 words, about 2 min14Basic Sciences: Anatomy, Physiology, Biochemistry and Pharmacology
This domain tests the basic science substrate that explains clinical dentistry: cranial nerve anatomy, calcium homeostasis, collagen biochemistry, and drug mechanisms relevant to dental practice. Trigeminal nerve: ophthalmic (V1), maxillary (V2) and mandibular (V3) divisions; V3 is motor to muscles of mastication and carries the inferior alveolar, lingual and buccal nerves.
