Oral and Maxillofacial Surgery for BDS

High-yield topics

• Principles of exodontia: indications, contraindications, assessment and the steps of uncomplicated extraction.
• Exodontia armamentarium — forceps and elevators, their parts, principles and identification for spotters.
• Complications of tooth extraction: intraoperative and postoperative, post-extraction haemorrhage and oro-antral communication.
• Impacted teeth and third molar surgery, including Winter's and Pell and Gregory classifications.
• Dry socket: definition, risk factors, diagnosis and management.
• Odontogenic infections and the fascial spaces of the face and neck, including spread to the danger spaces and cavernous sinus.
• Ludwig's angina as an airway emergency: clinical features and management priorities.
• Osteomyelitis of the jaw, proliferative periostitis of Garré, osteoradionecrosis and medication-related osteonecrosis.
• Local anaesthesia in dentistry: agents, maximum doses, injection techniques and systemic toxicity.
• Medical emergencies in the dental clinic — syncope, anaphylaxis, hypoglycaemia, angina, asthma and seizures.
• Maxillofacial trauma: Le Fort classification of maxillary fractures, mandible fracture management and zygomatic complex fractures.
• Biopsy principles and the systematic investigation of an oral lesion, especially the non-healing ulcer.
• Cysts of the jaws versus odontogenic tumours, with ameloblastoma and odontogenic keratocyst in detail.
• Oral cancer and premalignant lesions: leukoplakia, erythroplakia and oral submucous fibrosis.
• Trigeminal neuralgia, TMJ dislocation and TMJ ankylosis, plus basics of dental implants, orthognathic surgery and cleft lip and palate.

How to study Oral Surgery for BDS university exams

Anchor every topic to anatomy, then to a decision. Muscle attachments — buccinator, mylohyoid, masseter, medial pterygoid — explain where infections spread; the course of the inferior alveolar and lingual nerves explains third molar risk; the pillars of the midface explain fracture fixation. Learn each major condition as a five-line frame: definition, classification, clinical features, investigations, treatment, and always be able to give the first step when a patient is in danger, such as securing the airway in Ludwig's angina. Long answers in the university paper follow predictable patterns — aetiology, classification, clinical features, radiology, management, complications — so practise writing these frames against time. Pair every disease with its classical radiograph: the soap-bubble multilocular radiolucency of ameloblastoma, the sequestra of osteomyelitis, the displaced condyle, the step in the infraorbital rim. Revise with your clinical posting log beside you, because examiners increasingly frame theory questions around cases you should have seen.

Practical and viva preparation

The spotters and viva are where marks are won cheaply. Learn the instruments by handling them: identify each forceps by jaw shape and the teeth it is made for, and explain elevators by lever, wedge and wheel-and-axle principles. Rehearse the steps of extraction aloud until they flow — anaesthesia, detachment of the gingival attachment, luxation, delivery, socket care — because the viva examiner asks you to narrate them. Keep a personal radiograph album from postings: orthopantomograms of fractures, impacted third molars and cysts, each labelled with the classical signs. For short cases, practise presenting in a fixed format — history, examination findings, diagnosis, investigations, plan — and know the emergency algorithms cold: the adrenaline dose for anaphylaxis, the position for syncope, the reduction manoeuvre for a dislocated temporomandibular joint. A short log of assisted extractions and observed cases, honestly maintained, gives you authentic material for every viva question.
