Running Command

cd /home/daytona/workspace/attachments/fbf4c580-9e1a-40be-8a88-8e6d070ffbc7/ && python3 -c " import pdfplumber with pdfplumber.open('ORAL-PATH-QP.-2011-2025.pdf') as pdf: print(f'Total pages: {len(pdf.pages)}') # Extract first 5 pages to understand structure for i in range(min(5, len(pdf.pages))): print(f'\n=== PAGE {i+1} ===') text = pdf.pages[i].extract_text() print(text[:2000] if text else 'No text') "

The PDF appears to be scanned (image-based). Let me use OCR to extract the text.
Running Command

cd /home/daytona/workspace/attachments/fbf4c580-9e1a-40be-8a88-8e6d070ffbc7/ && python3 -c " import subprocess # Convert PDF pages to images and OCR them result = subprocess.run(['pdftoppm', '-r', '200', '-png', 'ORAL-PATH-QP.-2011-2025.pdf', '/tmp/oral_path_page'], capture_output=True, text=True) print('pdftoppm result:', result.returncode, result.stderr[:200]) import os files = sorted([f for f in os.listdir('/tmp') if f.startswith('oral_path_page')]) print(f'Generated {len(files)} images') print(files[:5]) "

Running Command

python3 -c " import subprocess, os all_text = [] for i in range(1, 31): img = f'/tmp/oral_path_page-{i:02d}.png' result = subprocess.run(['tesseract', img, 'stdout', '--oem', '1', '--psm', '6'], capture_output=True, text=True) text = result.stdout.strip() all_text.append(f'\n=== PAGE {i} ===\n{text}') full_text = '\n'.join(all_text) with open('/tmp/oral_path_ocr.txt', 'w') as f: f.write(full_text) print(f'Total chars: {len(full_text)}') print(full_text[:3000]) "

I can see all 30 pages of question papers from 2011-2025. Now let me read the full OCR text and then use the medical library to provide comprehensive answers. Let me first read all the questions.

Now I have a clear picture of the question papers. This is a comprehensive ORAL PATHOLOGY AND MICROBIOLOGY (3rd BDS) question paper compilation from 2011-2025 from RGUHS. Given my budget constraints, I'll use the medical library to look up key topics and provide comprehensive answers. Let me now compile all unique questions and provide model answers using my medical knowledge and the library.

I now have enough information from the library and my expert medical knowledge to write comprehensive answers. Given the large number of questions across 30 pages, I'll now compose detailed model answers organized by topic. Let me write these out systematically.
