General Surgery for BDS

Why this subject matters

Dental surgeons deal with wounds, infections, bleeding and swellings every week. The principles taught in General Surgery are the same ones that decide how you handle an extraction socket, an abscess or a medically compromised patient.

The subject also underpins Oral and Maxillofacial Surgery. Facial space infections, head and neck cancer and trauma all rest on the basics of inflammation, healing, shock and oncology learnt here.

How to study this subject

1. Start with the basics. Learn inflammation, healing, infection and shock first, since later chapters keep returning to them.
2. Use a fixed template for every disease. Write down the definition, causes, clinical features, investigations, treatment and complications in the same order each time.
3. Learn classifications and causes as lists. Examiners often ask for these directly, so a clean list scores well in short notes.
4. Link each topic to dentistry. Ask how the topic changes your approach to a patient in the dental chair, for example in bleeding disorders, infections or head and neck swellings.
5. Practise long and short answers. Write diagrams, flowcharts and headings by hand, because presentation affects marks in a theory paper.
6. Prepare for viva. Be ready to describe a swelling, a wound or a suture material aloud in a few clear sentences.

Revision strategy

Plan at least three revision rounds before the examination. In the first, complete each topic in short summary notes. In the second, revise only those notes and mark weak areas. In the third, concentrate on frequently asked questions, classifications and diagrams.

Give extra revision time to the topics that appear again and again in university papers: wound healing, shock, haemorrhage, blood transfusion, infections, tumours and neck swellings. Revise rare topics more lightly.

In the last fortnight, solve previous-year questions from your own university under timed conditions. Review every wrong or incomplete answer and correct it in your notes.
